Student Name: SCIN 401 Mammalogy Case Study Assignment Week 7: Home Range Calculations Read the following information about home ranges and the case example. Follow the directions for the calculations. Answer the essay question completely using thoughtful ideas, the course text, and outside reference sources. Proofread answers for potential writing errors. Part A. Background on Home Ranges Intraspecific competition for resources and other behavioral interactions can drive territoriality and establishment of home ranges. Many mammal species exhibit forms of territoriality that result in home ranges.A home range is defined by Burt (1943) as “that area traversed by the individual in its normal activities of food gathering, mating, and caring for young.” Mammals known to exhibit territoriality occur in the orders Perissodactyla, Carnivora, Lagomorpha, Rodentia, Primates, Chiroptera, and Socicomorpha (Vaughan et al. 2011). Study of home ranges can increase knowledge about the species ecology, including habitat quality, and behavior. Calculation of home ranges from raw location data is beyond the scope of this case study; however, it is valuable to know in general terms how home ranges are calculated. Generally individuals are marked and then location data is gathered by capture-recapture, observation capture, radio-telemetry, and/or satellite data (e.g., collars with GPS transmitters have been used on large species like polar bears [http://alaska.usgs.gov/science/biology/polar_bears/tracking.html]). Location data is graphed usually with the aid of mapping software like ArcGIS (http://www.esri.com/software/arcgis/index.html) or even Google Earth Pro (Taulman, 2010). Statistical techniques are used to calculate and analyze home ranges such as minimum convex polygons, bivariate ellipses, adaptive and fixed kernels, and even a Brownian bridge technique (Mitchell, 2006). Home ranges can be overlayed with other GIS data layers (e.g., habitat cover type, elevation, water sources, etc.), to create powerful analyses and hypotheses for further research.

Genotyping an invasive vine
The climbing vine kudzu, a member of the leguminous
pea family (Fabaceae), was introduced into the USA
from its native Asia in the 1800s. It was initially lauded
for efficacy in erosion control along highways and as a
high-quality grazing crop for livestock. P. montana var.
lobata has since become a truculent invasive, spreading
via vegetative runners and seed dispersal. Seven
million acres of the American southeast are now
plagued by this vine.

Population Projection of Bald Eagles
This document compares different techniques for projecting the population of bald eagles using historical count data from 1957 to 1987. It finds that the population projections differ significantly depending on which counting method is used, with the Fawks study predicting a growth rate that differs statistically from current known population sizes. Different growth models are best fits for the data from each counting method. The document cautions that not all population models are literally true, but some can still be useful for management purposes like determining when a species might be delisted.

This study examined how the space-use patterns of golden jackals are affected by proximity to human villages in Israel. The researchers radio-tracked 16 jackals, 8 near villages and 8 further away. They found that jackals near villages had smaller home ranges and core areas than those further away. Jackals near villages also moved less during the day than those in more natural areas. However, nighttime movement did not differ between the two groups, though jackals near villages moved in a less directional manner. The presence of abundant, predictable food sources from human villages compressed jackal space use and altered their movement patterns.

Randomized government safety inspections of workplaces in California were found to reduce worker injury rates and costs with no detectable negative effects on employment, sales, credit ratings, or business survival. Compared to similar uncontrolled workplaces, randomly inspected establishments experienced a 9.4% decline in injury rates and a 26% reduction in injury costs. The study analyzed data from 409 randomly inspected workplaces matched with 409 similar uncontrolled workplaces, finding that improved safety inspections can achieve their goal of protecting workers without harming businesses.

This study examined spatial correlation of wildlife-friendly landscaping features between neighboring properties in residential transects near forest preserves in Chicago. Yard surveys were conducted on properties in 26 transects to assess vegetation layers and wildlife features. Mantel tests found low overall correlation between neighboring yards, though some transects like Wilmette showed higher similarity over longer distances. Front yards tended to be more alike between neighbors than back yards. While wildlife features showed some localized correlation, levels dropped off rapidly with distance. The results suggest neighbors primarily influence only immediate adjacent properties in their landscaping choices.

This document provides an introduction and methods for collecting vegetation plot data using the relevé method in Minnesota. It defines a relevé as a delimited vegetation plot with a list of plant species and their cover, along with site data. Over 9,000 relevés have been collected in Minnesota and are stored in a database. The handbook establishes standards for collecting relevés to describe and classify native plant communities and provides guidance on plot size, location, and data collection and recording.

This study examined how habitat complexity affects brain structure in the lesser earless lizard. It found that lizards living in the more complex Chihuahuan Desert habitat had larger medial cortices, the brain region responsible for spatial memory and navigation, compared to those in the less complex White Sands habitat. Additionally, in the more complex desert habitat, male lizards had larger medial cortices than females, likely due to males' greater range of movement. The results support the hypotheses that habitat complexity is positively correlated with medial cortex size, and that sex differences exist in brain structure.
hummingbirds
Male Anna's hummingbirds were tested on their ability to remember the location of a rewarding food source over multiple trials. Larger crown size was positively correlated with total errors made and improvement in performance over trials, suggesting larger crowns are less efficient. Smaller crowns and more red-colored gorgets were correlated with better performance, making fewer errors. The results indicate plumage ornamentation may reveal cognitive abilities important for foraging, with females benefitting from selecting males with traits signaling better learning and memory.

This document describes a study that evaluates different metrics for quantifying the amount of spatial information encoded by neurons. The researchers simulated neurons with various spatial firing properties and measured three information metrics: bits per spike (Ispike), bits per second (Isec), and mutual information (MI). They found Ispike and Isec did not always correlate well with decoding performance, whereas MI did. The researchers then proposed normalizing the metrics using surrogate analyses to better estimate the true spatial information. Analysis of real neuron data supported the findings from simulations.

1. The document discusses three main questions regarding human evolutionary genetics: the debate between hybridization models vs. the Southern dispersal route out of Africa, the coevolution of cultural and biological diversity, and challenges to the persistence of racial paradigms given genomic data.
2. Regarding the first question, the author notes several problems with hybridization hypotheses and presents evidence supporting an earlier dispersal of modern humans out of Africa via a Southern route, avoiding contact with Neanderthals.
3. For the second question, the author reviews evidence that increases in brain size did not necessarily correlate with genes associated with cognitive functions, and that cultural and linguistic changes likely evolved in parallel with biological changes.

A new species of porcupine, Coendou speratus, has been discovered in the Atlantic forest of northeastern Brazil. C. speratus is smaller than the similar species C. prehensilis and C. nycthemera. It has tricolored dorsal quills with brownish red tips, unlike the bicolored quills of C. nycthemera. Molecular and morphological analyses distinguish C. speratus as a unique species within the genus Coendou. The discovery adds to knowledge of the biodiversity of the important but threatened Atlantic forest ecosystem.

This document discusses challenges and opportunities for discovering and documenting biodiversity in the current information age. It argues that current taxonomic processes are too slow and that new approaches are needed to integrate distributed data sources and leverage community contributions. Specifically, it proposes:
1) Publishing new biodiversity data prior to formal documentation to accelerate discovery.
2) Developing automated workflows and online workspaces to integrate phylogenetic, distribution, and trait data.
3) Enabling community participation through open data sharing and collaborative annotation platforms.

Lab evolution
This document provides instructions for a laboratory activity on evolution. The activity has two parts: (1) distinguishing heritable and non-heritable traits within populations using published data on different species, and (2) simulating natural selection on a population of sticks of different colors scattered in different environments. Students are asked to record data on initial and final population counts and proportions, perform statistical tests to analyze changes, and answer questions about heritability of traits, natural selection, and fitness of different individuals.

Perception of shapes targeting local and global

Background: Several researchers have found evidence for impaired global processing in the dorsal
visual stream in individuals with autism spectrum disorders (ASDs). However, support for a similar
pattern of visual processing in the ventral visual stream is less consistent. Critical to resolving the
inconsistency is the assessment of local and global form processing ability. Methods: Within the visual
domain, radial frequency (RF) patterns – shapes formed by sinusoidally varying the radius of a circle to
add ‘bumps’ of a certain number to a circle – can be used to examine local and global form perception.
Typically developing children and children with an ASD discriminated between circles and RF patterns
that are processed either locally (RF24) or globally (RF3). Results: Children with an ASD required
greater shape deformation to identify RF3 shapes compared to typically developing children, consistent
with difficulty in global processing in the ventral stream. No group difference was observed for RF24
shapes, suggesting intact local ventral-stream processing. Conclusions: These outcomes support the
position that a deficit in global visual processing is present in ASDs, consistent with the notion of Weak
Central Coherence. Keywords: Autism, local processing, global processing, ventral visual pathway,
radial frequency patterns. Abbreviations: ASD, autism spectrum disorder; TD, typically developing;
WCC, Weak Central Coherence; EPF, Enhanced Perceptual Functioning; RF, radial frequency; ADI-R,
Autism Diagnostic Interview – Revised.
Over the past three decades, several research groups
have proposed that the cognitive profile in autism
spectrum disorders (ASDs) is characterised by diffi-
culties in complex information processing (Bertone,
Mottron, Jelenic, & Faubert, 2005; Frith, 1989;
Minshew, Goldstein, & Siegal, 1997). In particular,
Weak Central Coherence (WCC) theory suggests that
individuals with an ASD demonstrate a relative fail-
ure to extract overall meaning, resulting in a reduced
awareness of the global aspects of stimuli in con-
junction with a relatively heightened awareness of
the details or parts of stimuli (Frith, 1989; Happé,
1999). Several studies have shown, however, that
integration abilities might be intact in ASDs (Mot-
tron, Burack, Stauder, & Robaey, 1999; Ozonoff,
Strayer, McMahon, & Filloux, 1994; Plaisted, Swet-
tenham, & Rees, 1999). To account for these data,
others have proposed, amongst several other
hypotheses, that individuals with an ASD show
‘Enhanced.

This document summarizes a study examining the geographic distribution of cytotypes (ploidy levels) in the grass Andropogon gerardii across North America. The study analyzed 352 individuals from 32 populations using flow cytometry to estimate ploidy. It found the two main cytotypes were hexaploid (6x) and enneaploid (9x). Enneaploids were more common in southern regions with reduced summer precipitation and greater temperature variation, while hexaploids dominated in northern areas. Nearly half of populations contained both cytotypes. The results suggest cytotype distribution is nonrandom and associated with environmental variables, and mixed-ploidy populations may be maintained by recurrent polyploid formation

Mantel tests found low overall correlation between neighboring yards, though some transects like Wilmette showed higher similarity over longer distances. Front yards tended to be more alike between neighbors than back yards. While wildlife features showed some localized correlation, levels dropped off rapidly with distance. The results suggest neighbors primarily influence only immediate adjacent properties in their landscaping choices.

This document provides an introduction and methods for collecting vegetation plot data using the relevé method in Minnesota. It defines a relevé as a delimited vegetation plot with a list of plant species and their cover, along with site data. Over 9,000 relevés have been collected in Minnesota and are stored in a database. The handbook establishes standards for collecting relevés to describe and classify native plant communities and provides guidance on plot size, location, and data collection and recording.

This study examined how habitat complexity affects brain structure in the lesser earless lizard. It found that lizards living in the more complex Chihuahuan Desert habitat had larger medial cortices, the brain region responsible for spatial memory and navigation, compared to those in the less complex White Sands habitat. Additionally, in the more complex desert habitat, male lizards had larger medial cortices than females, likely due to males' greater range of movement. The results support the hypotheses that habitat complexity is positively correlated with medial cortex size, and that sex differences exist in brain structure.
hummingbirds
Male Anna's hummingbirds were tested on their ability to remember the location of a rewarding food source over multiple trials. Larger crown size was positively correlated with total errors made and improvement in performance over trials, suggesting larger crowns are less efficient. Smaller crowns and more red-colored gorgets were correlated with better performance, making fewer errors. The results indicate plumage ornamentation may reveal cognitive abilities important for foraging, with females benefitting from selecting males with traits signaling better learning and memory.

This document describes a study that evaluates different metrics for quantifying the amount of spatial information encoded by neurons. The researchers simulated neurons with various spatial firing properties and measured three information metrics: bits per spike (Ispike), bits per second (Isec), and mutual information (MI). They found Ispike and Isec did not always correlate well with decoding performance, whereas MI did. The researchers then proposed normalizing the metrics using surrogate analyses to better estimate the true spatial information. Analysis of real neuron data supported the findings from simulations.

1. The document discusses three main questions regarding human evolutionary genetics: the debate between hybridization models vs. the Southern dispersal route out of Africa, the coevolution of cultural and biological diversity, and challenges to the persistence of racial paradigms given genomic data.
2. Regarding the first question, the author notes several problems with hybridization hypotheses and presents evidence supporting an earlier dispersal of modern humans out of Africa via a Southern route, avoiding contact with Neanderthals.
3. For the second question, the author reviews evidence that increases in brain size did not necessarily correlate with genes associated with cognitive functions, and that cultural and linguistic changes likely evolved in parallel with biological changes.

A new species of porcupine, Coendou speratus, has been discovered in the Atlantic forest of northeastern Brazil. C. speratus is smaller than the similar species C. prehensilis and C. nycthemera. It has tricolored dorsal quills with brownish red tips, unlike the bicolored quills of C. nycthemera. Molecular and morphological analyses distinguish C. speratus as a unique species within the genus Coendou. The discovery adds to knowledge of the biodiversity of the important but threatened Atlantic forest ecosystem.

This document discusses challenges and opportunities for discovering and documenting biodiversity in the current information age. It argues that current taxonomic processes are too slow and that new approaches are needed to integrate distributed data sources and leverage community contributions. Specifically, it proposes:
1) Publishing new biodiversity data prior to formal documentation to accelerate discovery.
2) Developing automated workflows and online workspaces to integrate phylogenetic, distribution, and trait data.
3) Enabling community participation through open data sharing and collaborative annotation platforms.

Perception of shapes targeting local and global
processes in autism spectrum disorders

Background: Several researchers have found evidence for impaired global processing in the dorsal
visual stream in individuals with autism spectrum disorders (ASDs). However, support for a similar
pattern of visual processing in the ventral visual stream is less consistent. Critical to resolving the
inconsistency is the assessment of local and global form processing ability. Methods: Within the visual
domain, radial frequency (RF) patterns – shapes formed by sinusoidally varying the radius of a circle to
add ‘bumps’ of a certain number to a circle – can be used to examine local and global form perception.
Typically developing children and children with an ASD discriminated between circles and RF patterns
that are processed either locally (RF24) or globally (RF3). Results: Children with an ASD required
greater shape deformation to identify RF3 shapes compared to typically developing children, consistent
with difficulty in global processing in the ventral stream. No group difference was observed for RF24
shapes, suggesting intact local ventral-stream processing. Conclusions: These outcomes support the
position that a deficit in global visual processing is present in ASDs, consistent with the notion of Weak
Central Coherence. Keywords: Autism, local processing, global processing, ventral visual pathway,
radial frequency patterns. Abbreviations: ASD, autism spectrum disorder; TD, typically developing;
WCC, Weak Central Coherence; EPF, Enhanced Perceptual Functioning; RF, radial frequency; ADI-R,
Autism Diagnostic Interview – Revised.
Over the past three decades, several research groups
have proposed that the cognitive profile in autism
spectrum disorders (ASDs) is characterised by diffi-
culties in complex information processing (Bertone,
Mottron, Jelenic, & Faubert, 2005; Frith, 1989;
Minshew, Goldstein, & Siegal, 1997). In particular,
Weak Central Coherence (WCC) theory suggests that
individuals with an ASD demonstrate a relative fail-
ure to extract overall meaning, resulting in a reduced
awareness of the global aspects of stimuli in con-
junction with a relatively heightened awareness of
the details or parts of stimuli (Frith, 1989; Happé,
1999). Several studies have shown, however, that
integration abilities might be intact in ASDs (Mot-
tron, Burack, Stauder, & Robaey, 1999; Ozonoff,
Strayer, McMahon, & Filloux, 1994; Plaisted, Swet-
tenham, & Rees, 1999). To account for these data,
others have proposed, amongst several other
hypotheses, that individuals with an ASD show

This document summarizes a study examining the geographic distribution of cytotypes (ploidy levels) in the grass Andropogon gerardii across North America. The study analyzed 352 individuals from 32 populations using flow cytometry to estimate ploidy. It found the two main cytotypes were hexaploid (6x) and enneaploid (9x). Enneaploids were more common in southern regions with reduced summer precipitation and greater temperature variation, while hexaploids dominated in northern areas. Nearly half of populations contained both cytotypes. The results suggest cytotype distribution is nonrandom and associated with environmental variables, and mixed-ploidy populations may be maintained by recurrent polyploid formation

The case of Welcome Israel provides another opportunity to analyze individual and organizational approach to change(s) and the impact of those changes. The case provides a synopsis with Ofra Sherman and Glaxo’s situations as the change was unfolding between these two firms. As you reflect on the change in this case study, respond to the following prompts as you prepare your DB thread for this assignment:
What did Glaxo-Welcome do? What should they have done?
Did Ofra Sherman do the right thing? What would you have done?
What was Ofra Sherman’s predicament? How did she get into it?
How do you evaluate her actions as described in the case?
RESPOND TO THIS POST FROM FERGUSON
Wellcome Israel is a pharmaceutical company operating in Israel. Wellcome is being acquired by Glaxo and soon will become Wellcome-Glaxo. This appears to be a hostile bid type takeover to create a large pharmaceutical company. All employees and management were extremely surprised by the takeover and are having a hard time processing it. The main them and problem that will be noted in this post is the lack of communication, direction and vision.
Glaxo-Wellcome is on the way to becoming one of the largest pharmaceutical companies in the world. There is an apparent hostile takeover in progress that no one including Wellcome management is aware of. As with any change there are periods of uncertainty, fear, and anxiety. The main focus is a general manager Ofra Sherman and her team who works for Wellcome Israel through Promedico. This takeover was done in a manner that is very disturbing in the fact that there was no communication and very little guidance throughout the entire process.
What they should have done is really quite simple and that is communicate. As I mentioned before change is a very anxious time and can lead to stress and poor work performance for those involved. “Good communication throughout every stage of the change process is vital to keep everyone informed and motivation levels high.” (Kirke 2012) This takeover shouldn’t have been a surprise to Wellcome and they should have been upfront with employees about what was going to occur and then once the takeover by Glaxo started the communication should have ramped up. I think one of the best ways to have handled this would have been to have teams from both companies setting up meetings so there was a continuous flow of information.
Ofra Sherman in my mind was in a very tough spot once again a lack of communication between all the parties really left her between a rock and a .

Strong acid versus strong base titration and weak acid versus strong base titration
http://group.chem.iastate.edu/Greenbowe/sections/projectfolder/flashfiles/stoichiometry/a_b_phtitr.html
First read the following article about pH indicators:
http://chemwiki.ucdavis.edu/Physical_Chemistry/Acids_and_Bases/Case_Studies/Acid_and_Base_Indicators
In this experiment you will be analyzing the neutralization between a strong acid and a strong base. According to the Arrhenius Acid-base Theory, when dissolved in water, an acid raises the concentration of hydrogen ion, H
+
while a base increases the hydroxide ion, OH
-
concentration. When reacted together the acid and base will neutralize each other according to the net ionic equation (1).
H
+
(aq) + OH
‐
(aq) → H
2
O(l) (1)
An acid is considered to be strong if it completely ionizes in water. In this lab, you will be using the strong acid, hydrochloric acid, HCl, to neutralize the strong base, sodium hydroxide, NaOH, according to the neutralization reaction below.
HCl(aq) + NaOH(aq) → NaCl(aq) + H
2
O(l) (2)
The progression of the reaction will be observed using a pH meter and a titration curve will be created using the experimental data. You will start with a sample containing only the acid and indicator and slowly add your standardized base. A titration curve is simply a plot of the pH of an acid versus the volume of base added, or vice versa. The titration curve gives a good description of how an acid-base reaction proceeds. The pH will start out low and acidic, then increase as it approaches the equivalence point, where the concentration of acid equals that of the base. Then as the solution becomes more basic, it will slowly rise and level off as an excess amount of base is added. Note that the equivalence point is slightly different from the endpoint of a titration. The endpoint is when the indicator changes color. This does not always correspond to the equivalence point.
As pre-laboratory preparation it is critical that you review the ideas on strong acid-strong base titration presented in your class readings.
Strong acid versus strong base
With your first sample, select an indicator from the two options and do a quick titration by adding 1 mL increments until you reach pH 2.5; then dropwise increments until you reach pH 10.7; after that add 1 mL increments until pH 11.5. Record your buret readings after the addition of each increment. Allow time for the reaction vessel to become equilibrated and for the pH reading to become stabilized and then record the pH value in your notebook alongside the buret reading. Leave an empty column between the buret reading and the pH in which to place the volume of NaOH added (difference between present buret reading and initial buret reading). Stop the titration when you have reach.

SEC450 ACL Tutorial
This document highlights the most important concepts on Access Control List (ACL) that
you need to learn in order to configure ACL in CLI. This tutorial does not intend by any
mean to cover all ACL applications, but only those scenarios used in then SEC450
iLabs.
Introduction to Access Control List
A host-based firewall essentially works closing and/or opening ports in a
computer. The engine behind firewalls is built with Access Control Lists (ACL).
Network-based firewalls are implemented in device-specific appliances and
routers. Basically, firewalls in routers filter packets through interfaces to permit
or deny them.
Ports are layer-4 address specified in TCP/IP protocol suit that identify
networking processes running in clients and servers.
ACLs are configured using shell-specific commands. In Cisco IOS, CLI
commands.

Student Name Brief #5 Use of Audit Software: Review and Survey Date
Central Message: Auditing has had to change from “around the computer” to “through the
computer” due to sources only being available in electronic form. CAATs and CAATTs improve
efficiency and effectiveness of audits. A variety of standards and statements were issued because
new guidance was necessary once the growth of IT affected the nature, timing, and extent of audit
procedures. Continuous auditing is the key to improving the efficiency and effectiveness of audits.
Author’s Theme: Auditors are advised to use CAATs to gather evidence so that they can increase
the efficiency of inspection and analytical review. One of the many statements released on IT, SAS
94, stressed that IT’s impact on internal control is a result of the nature and extent of the system’s
complexity rather than the size of the firm, which is why auditing through the computer is
important when testing controls. Auditors can pinpoint the risk areas and thus have a better idea of
what to inquire when questioning management; improving the quality of the evidence and thus the
audit. Importance: Advancement in information technology has a direct impact on business
processes and the audit. Increasingly, auditors are required to perform audits in computerized
environments; therefore, additional standards are required to ensure that financial statements
auditors continue to perform high quality audits. Conclusion/Opinions: (1) The author concludes
that auditing through the computer is important when testing controls because of the impact IT has
on internal control. GAAS field work #2 supports this because the IT system is a part of the entity’s
environment, and especially, when it is complex, the auditor must audit through the computer to
adequately assess internal control risk. (2) Using CAATs can increase the efficiency of audit
procedures. SAS No. 106 indicates that CAATs allow auditors to inspect electronic evidence directly.
(3) Auditors should use data analysis from audit software in order to pinpoint the risk areas and
gain a better idea of what to ask management. AS # 5 states that risk assessment underlies the
entire audit process, including the determination of significant accounts and relevant assertions,
selecting controls to test, and determining the evidence necessary.

Transmission Unaccomplished, John Authers September 24
th
2010 Financial Times Page 12
2. Article Summary:
“Transmission Unaccomplished” written in the Lex section of Friday’s Financial Times
offers an interesting and simplified perspective of the complex and sophisticated purpose and
workings of monetary policy. At a time when the world is reeling from the effects of
misunderstood monetary policy in the United States and other nations around the globe, this
article clearly cuts to the heart of the matter, provides a simple, easy to understand analogy
relating monetary policy to an automobile. The authors describe the key moving parts of the
economy as they correlate to their counterparts in an automobile. While he labor and
resources constitute the fuel of the economy, technology and institutions correspond to the
engine, and commerce is depicted as wheels. The financial system is the transmission,
responsible for moving the power and energy created by the fuel and engine to the wheels.
This simple analogy helps frame the context for the reason why central bankers – the
transmission mechanics – were facing increasing difficulty. In particular, the 1.6 % drop in
the dollar’s value, the lack of real economic turn-around, and the lagging increase in GDPs
around the world. The authors seem to think the US, despite an increasing saving rate and
10% deleveraging, still has long ways to go on the road to recovery, and the automobile
analogy suggests, is in need of significant repairs and rebuilding before it is truly road worthy.
3. How is the article is related to the readings and class discussions?
The concepts in the article mesh with the readings in chapters 3 – 5 as a current, real world
depiction of how monetary policy influences decisions in economics. The article highlights the
need for central bankers to properly manage monetary policy in order to maintain the
transmission of the vehicle, and keep the proper amount of power moving from the motor to the
wheels. It questions the true value of quantitative easing, and highlights the ramifications of
pursuing excessive QE as a policy. Just as was discussed in the first five chapters of the text
book, monetary policy involves a delicate balance of adjusting interest rates, setting currency
value, and establishing guidelines that enable prosperity and growth. The article also identifies
too much intervention as a possible means for enhancing the problems we face, rather than
ameliorating the problems.
4. What did I learn from this article?
This article certainly helped put monetary policy, something I seem to be familiar with only
through studying politics and economics, into a very concise, easy to understand framework that
enables a deeper understanding of greater associated issues. I learned that the US liabilities are

This Dissertation explores the particular circumstances of Mirzapur, a region located in the
core of India. Mirzapur, with its varied terrains and abundant biodiversity, offers an optimal
environment for investigating the changes in vegetation cover dynamics. Our study utilizes
advanced technologies such as GIS (Geographic Information Systems) and Remote sensing to
analyze the transformations that have taken place over the course of a decade.
The complex relationship between human activities and the environment has been the focus
of extensive research and worry. As the global community grapples with swift urbanization,
population expansion, and economic progress, the effects on natural ecosystems are becoming
more evident. A crucial element of this impact is the alteration of vegetation cover, which plays a
significant role in maintaining the ecological equilibrium of our planet.Land serves as the foundation for all human activities and provides the necessary materials for
these activities. As the most crucial natural resource, its utilization by humans results in different
'Land uses,' which are determined by both human activities and the physical characteristics of the
land.
The utilization of land is impacted by human needs and environmental factors. In countries
like India, rapid population growth and the emphasis on extensive resource exploitation can lead
to significant land degradation, adversely affecting the region's land cover.
Therefore, human intervention has significantly influenced land use patterns over many
centuries, evolving its structure over time and space. In the present era, these changes have
accelerated due to factors such as agriculture and urbanization. Information regarding land use and
cover is essential for various planning and management tasks related to the Earth's surface,
providing crucial environmental data for scientific, resource management, policy purposes, and
diverse human activities.
Accurate understanding of land use and cover is imperative for the development planning
of any area. Consequently, a wide range of professionals, including earth system scientists, land
and water managers, and urban planners, are interested in obtaining data on land use and cover
changes, conversion trends, and other related patterns. The spatial dimensions of land use and
cover support policymakers and scientists in making well-informed decisions, as alterations in
these patterns indicate shifts in economic and social conditions. Monitoring such changes with the
help of Advanced technologies like Remote Sensing and Geographic Information Systems is
crucial for coordinated efforts across different administrative levels. Advanced technologies like
Remote Sensing and Geographic Information Systems

Changes in vegetation cover refer to variations in the distribution, composition, and overall
structure of plant communities across different temporal and spatial scales. These changes can

Student Name SCIN 401 MammalogyCase Study Assignment Wee.docx
- 1. Student Name: SCIN 401 Mammalogy Case Study Assignment Week 7: Home Range Calculations Read the following information about home ranges and the case example. Follow the directions for the calculations. Answer the essay question completely using thoughtful ideas, the course text, and outside reference sources. Proofread answers for potential writing errors. Part A. Background on Home Ranges Intraspecific competition for resources and other behavioral interactions can drive territoriality and establishment of home ranges. Many mammal species exhibit forms of territoriality that result in home ranges.A home range is defined by Burt (1943) as “that area traversed by the individual in its normal activities of food gathering, mating, and caring for young.” Mammals known to exhibit territoriality occur in the orders Perissodactyla, Carnivora, Lagomorpha, Rodentia, Primates, Chiroptera, and Socicomorpha (Vaughan et al. 2011). Study of home ranges can increase knowledge about the species ecology, including habitat quality, and behavior. Calculation of home ranges from raw location data is beyond the scope of this case study; however, it is valuable to know in general terms how home ranges are calculated. Generally individuals are marked and then location data is gathered by capture-recapture, observation capture, radio-telemetry, and/or satellite data (e.g., collars with GPS transmitters have been used on large species like polar bears [http://alaska.usgs.gov/science/biology/polar_bears/tracking.ht ml]). Location data is graphed usually with the aid of mapping software like ArcGIS (http://www.esri.com/software/arcgis/index.html) or even Google Earth Pro (Taulman, 2010). Statistical techniques are used to calculate and analyze home ranges such as minimum convex polygons, bivariate ellipses, adaptive and fixed kernels,
- 2. and even a Brownian bridge technique (Mitchell, 2006). Home ranges can be overlayed with other GIS data layers (e.g., habitat cover type, elevation, water sources, etc.), to create powerful analyses and hypotheses for further research.

Mammalogy(course text), Jones & Bartlett, Sudbury MAPart B. Case Example ( Photo Credit: Sally King, U.S. National Park Service )In this case example, three populations of Abert Squirrel (Sciurusaberti) also called the tassel-eared squirrelwere studied. Sciurusaberti is found in ponderosa (Pinuspondersa) forests inWyoming, Colorado, New Mexico, Arizona, Utah, and northern Mexico(Mejia, 1999).There are up to eight recognized subspecies that are distinct due to geographic isolation and discontinuous ponderosa forest distribution (Lamb et al. 1997). They have an integrated ecology with ponderosa pine which they rely on for feeding, nesting, and cover(Grotheret al. 2005). Optimal habitat for Sciurusabertiis late successional mixed age ponderosa pine forests. A combination of management practices such as logging, grazing, and wildfire suppression haveresulted in homogenous even age stands that are suboptimal squirrel habitat (Grotheret al. 2005). In this case example, home range distributions of three isolated populations of Sciurusaberti in
- 3. Colorado were measured by radio telemetry and observation catching. Data was analyzed using ArcGIS software with resulting average home range sizes for radio tagged individuals.

Home Range Calculation For this case study use the data for each population to calculate the average (mean) home range and standard deviation. Calculations can be done manually or by Excel (use Summary Statistics). An arithmetic mean is calculated by the sum of the elements divided by the total number of elements. In this assignment take each home range size for each individual and sum then divide the sum by the number of home ranges. The standard deviation is a measure of central tendency or variation in the data. Standard deviation is calculated as the difference of each element from the mean: Results

Home Range Conclusions and Analysis Utilizing and specifically citing the data and results of home range data and compare and contrast the three populations. Propose at least two alternative hypotheses (reasons) for the differences in the data.Propose how each hypothesis could be tested. Discussion should be a minimum of 300 words and contain significant thought and analysis and utilize at least two reference sources in APA. Some questions you should answer include: · What could cause the spatial pattern observed in each population? · What could cause the difference in the average home range size? · What data would you collect to test your hypothesis?
