Microscopy is the technical field of using microscopes to view objects and areas that cannot be seen with the naked eye. There are several types of microscopes, including optical microscopes, electron microscopes, and scanning probe microscopes. Optical microscopes use lenses to magnify objects using visible light, while electron microscopes use electron beams which have much shorter wavelengths allowing for higher resolution images. Scanning probe microscopes use a physical probe that scans over a sample to characterize topography and other properties. Sample preparation and different imaging modes are used to reveal microstructural features for analysis.

This document discusses biomass power plants and provides calculations to determine the amount of biomass needed to generate 1 megawatt hour (MWh) of electricity. It explains that biomass is considered carbon neutral, as long as it is replanted and harvested sustainably. Common sources of biomass for fuel are then outlined, along with their composition and heating values. A simple calculation is presented that determines about 0.72 kilograms of biomass on a moisture-and-ash-free basis is needed to generate 1 MWh, with adjustments made depending on the biomass moisture content and ash percentage. Annual biomass requirements are estimated for a sample 5 megawatt biomass power plant.
The document discusses microscopy and the light microscope. It describes the basic components of a microscope, including a light source, specimen, and lens system to magnify the image. There are two main types: the simple microscope, which uses a single lens, and the compound microscope, which has multiple lenses for greater magnification and resolving power. The compound microscope typically has an objective lens, ocular lens, mechanical stage, light source, and focus knobs. It forms a real, inverted image with the objective and a further magnified virtual image with the ocular lens. Microscopes are widely used in biology and medicine to view specimens that are too small to see with the naked eye.
The document discusses transmission electron microscopy (TEM) and tissue sample preparation for TEM analysis. TEM uses electron beams instead of light for higher magnification imaging. Tissue must be carefully prepared through chemical fixation, dehydration, resin infiltration and sectioning. Samples are fixed in chemicals like glutaraldehyde and osmium tetroxide to preserve structures. They are then dehydrated in ethanol, infiltrated with resin for embedding, and ultrathin sections are cut and stained for viewing under the TEM. This allows high resolution imaging of cell and tissue structures down to the nanometer level.

The scanning transmission electron microscope (STEM) uses a finely focused electron beam that scans across the sample in a raster pattern. The STEM provides atomic resolution imaging and analysis through detectors like the EELS spectrometer, bright-field detector, and annular dark-field detector. Scan coils are used to scan the beam across the sample, while the condenser lens demagnifies the electron crossover point for high magnification imaging. The STEM has various applications in materials science and biology for characterizing nano- and atomic-scale structures.

This document discusses biomass and biogas. It defines biomass as plant matter created through photosynthesis. Biomass includes terrestrial and aquatic plants, crop residues, and organic waste. Biogas is produced through the anaerobic digestion of biomass by bacteria. It is composed primarily of methane and carbon dioxide. The document outlines the three stages of biogas production and describes common types of biogas digesters, including floating dome, fixed dome, Janata, and Deenbandhu models. It discusses the applications of biogas for lighting, cooking, and electricity generation.
Biogas is a renewable energy source produced through the anaerobic digestion of organic matter such as manure, sewage, and crops. It primarily consists of methane and carbon dioxide, which can be captured in a biogas plant and used for heating, power generation, as a vehicle fuel, or injected into gas networks, providing environmental and economic benefits.

The document discusses how plant phenology, the timing of recurring life cycle events, is affected by climate change. As temperatures increase, many plant species are flowering and undergoing other phenological events earlier in the spring. However, some late summer species may shift to later dates. This divergence could impact species interactions and ecosystem functioning. Process-based models are useful tools to project future phenology under climate change scenarios, though more data is needed to improve their accuracy, especially regarding responses to additional factors like drought and frost damage.

Ecological Genetics: Adaptation and Natural Selection Jaycris Agnes
The document discusses ecological genetics and natural selection. It defines key terms like genetic variation, mutation, genetic recombination, and sources of genetic variation. It describes Darwin's theory of natural selection as the differential survival and reproduction of individuals based on heritable traits that provide advantages in their environment. The document provides examples of natural selection including directional, stabilizing, and disruptive selection. It also discusses evolution as a change in gene frequencies over time due to factors like natural selection, genetic drift, and mutations. Adaptive radiation is defined as the process by which one species diversifies into multiple species occupying different ecological niches.
Essential Biology 4.3 Theoretical GeneticsStephen Taylor
The document provides a series of questions on genetics and heredity for students to answer. It includes questions about genotypes and phenotypes, Mendelian inheritance patterns such as dominant/recessive and codominant alleles, monohybrid and test crosses, pedigree charts, sex-linked traits and disorders like hemophilia and color blindness. Students are asked to complete tables, diagrams, calculations and explain concepts. Sources should be cited using CSE style and relevant terms highlighted before and after class.
Lee Kuan Yew was born in 1923 in Singapore to a middle-class family. He helped found the People's Action Party in 1954 and led them to victory in 1959, becoming Singapore's first prime minister. As prime minister, Lee transformed Singapore's economy and established it as a modern, wealthy nation. However, tensions caused Singapore to leave Malaysia in 1965. Lee remained an influential figure, resigning as prime minister in 1990 but continuing to offer advice. He worked tirelessly to build Singapore until his death in 2015.
This document provides information about population genetics and the Hardy-Weinberg principle of genetic equilibrium. It defines key population genetics concepts such as gene pool, allele frequencies, and genotypes. It describes the five conditions required for Hardy-Weinberg equilibrium: large population size, random mating, no mutations, no migration, and no natural selection. Examples are provided to demonstrate how to calculate allele and genotype frequencies using the Hardy-Weinberg equation.
Population Genetics 2015 03-20 (AGB 32012)Suvanthinis
The document discusses Hardy-Weinberg equilibrium, which states that allele and genotype frequencies in a population will remain constant from one generation to the next if the population is large, randomly mating, and not experiencing mutation, immigration, emigration or natural selection. It defines key population genetics terms like population, gene pool, allele frequency. It outlines the five conditions for Hardy-Weinberg equilibrium and provides an example calculation of genotype frequencies given allele frequencies in a population of cats. Factors that can disrupt Hardy-Weinberg equilibrium include small population size, non-random mating, mutation, migration, and natural selection.
Population genetics is the study of genetic variation within populations. A population's gene pool contains all the alleles of all individuals. Under Hardy-Weinberg equilibrium, allele frequencies remain constant between generations if there is no mutation, migration, genetic drift, or natural selection. Five agents cause evolution: mutation, gene flow, genetic drift, nonrandom mating, and natural selection, which is the only mechanism that leads to adaptation. Natural selection maintains genetic variation and can preserve polymorphisms through mechanisms like heterozygote advantage.
This document discusses factors that affect genetic variation and change in populations, including evolution, natural selection, mutations, migration, and genetic drift. It provides details on each factor and how they influence allele frequencies in a gene pool over multiple generations, leading to evolution and potentially new species. Examples are given to illustrate concepts like founder effects and bottleneck effects on small populations.
This document discusses key concepts in population genetics, including defining a population as a group of the same species living in a specific area. It provides an example of studying the genetics of a population of racers lizards, looking at the frequency of dominant and recessive alleles for stripe color. The values for p (frequency of dominant allele) and q (frequency of recessive allele) are calculated based on observing 110 lizards with the dominant white stripe allele out of 200 total alleles observed. This yields values of p=0.55 and q=0.45 for this population.
XIII World Forestry Congress, Buenos Aires, Argentina 2009Dr. Amalesh Dhar
The document summarizes research on the biodiversity and genetic structure of English yew (Taxus baccata L.) populations in Austria. Regeneration was found to be limited by browsing and lack of light. Pole stand health varied between sites, with differences in diameter distribution. Genetic analysis found moderate genetic variation and inbreeding within populations. Monitoring, thinning, and protection from browsing were recommended to improve regeneration and conservation status.
Current applications of biotechnology to forestry are modest, especially when compared to agriculture or pharmaceuticals. However, the potential for application of biotechnology to forestry and forest plantations is great.
1st European Congress of Conservation Biology, Hungary 2006Dr. Amalesh Dhar
This document evaluates six management strategies for an endangered population of Taxus baccata (English yew) in Austria using population viability risk management (PVRM) and the analytical hierarchy process (AHP). Strategy IV was found to best maintain viability by enhancing genetic variation, improving light availability, and reducing browsing pressure through fencing. A sensitivity analysis showed strategy IV had the highest priority across different scenarios, making it the overall best compromise solution.
This document provides a preliminary proposal to study polypore fungi in forests on Haida Gwaii. The proposal involves studying polypore biodiversity and abundance across forest stands of different ages and management regimes using GPS-linked photography. It also proposes investigating nutrient transfer between polypore mycelia and ectomycorrhizal fungi using isotope labeling in laboratory microcosms. The proposal notes that polypores play an important role in forest ecology and many have medicinal properties, but they remain understudied.
This document discusses how research can contribute to future resilient landscapes based on case studies of woodland habitats. It begins by outlining the structure of the talk and then discusses primary research on tree pathogens, dependent species, and habitat configuration. It next discusses synthesizing research findings through data collation and meta-analyses to assess impacts on dependent species, alternative host trees, and climate change. The document concludes by recommending simplified databases, woodland management guidance, and spatial modeling to inform management decisions and aid the persistence of biodiversity dependent on trees under threat.
This document summarizes a study that screened 12 cultivars from three ornamental Tagetes species (T. patula, T. tenuifolia, and T. erecta) for drought tolerance. Plants were subjected to a 3-week drought stress treatment by stopping watering. Various plant growth parameters, photosynthetic pigments, osmolytes, oxidative stress markers, and antioxidants were then measured and compared between stressed and unstressed plants. On average, T. erecta proved more drought tolerant than the other two species, though tolerance varied within each species. Principal component analysis identified the traits most associated with drought tolerance and the most tolerant cultivars. The results indicate drought tolerant Tagetes
This document summarizes a study that evaluated the risk of plant species introduced into botanical gardens becoming invasive weeds using a Weed Risk Assessment (WRA). The study analyzed data on plant introductions at two botanical gardens to compare risk scores between conservation species and horticultural introductions. It found conservation species had significantly lower and less variable risk scores than horticultural species. No species scored above the threshold for high risk of invasiveness. The study concludes the WRA is an effective tool for evaluating managed relocations of plant species into botanical gardens, especially when uncertainty exists about a species' risk of becoming invasive.
Tree regeneration, Fenner School July 2009joernfischer
The document summarizes research on tree regeneration in Australia's temperate grazing zone. It finds that under current grazing practices, trees are not regenerating at most sites due to lack of seedlings. If practices do not change, millions of hectares currently supporting tens of millions of trees could become treeless. The research identifies grazing regime, tree density, and soil nutrients as factors influencing regeneration, finding that ungrazed areas and fast livestock rotation support more regeneration than continuous grazing.
The Designation & Management of Threatened Species: is there any point?Mario Balzan
The management of threatened species is an important practical way in which conservationists can intervene with extinction process and reduce the loss of biodiversity by ensuring some (high) probability of long-term species survival (Young, 1994; Norris, 2004). Though maintaining the whole ecosystem is often the target of conservationists, if a population is severely threatened this may not be sufficient. A more direct population management may be required (Hunter, 1996). To conserve such rare species there is a critical need to assess the impacts of threats on the long term survival of an individual population. This requires detailed information about the biology of the species concerned, the habitat it prefers, and the factors that might affect both of these (Root, 1998). Natural resource agencies worldwide develop species recovery plans that specify threats, propose targets required for recovery, and evaluate the extent to which habitat alteration and restoration may influence species decline and recovery (Good et al. 2003)
Eriophyoid Mites as Weed Biological Control Agenteidmk230
Eriophyoid mites have potential as biological control agents for invasive weeds. Several species of eriophyoid mites have been successfully introduced and established to control various weed species. Examples discussed include Aceria chondrillae, which forms galls on Chondrilla juncea (skeleton weed) in Australia, reducing its growth and reproduction. Aceria malherbae also forms galls on Convolvulus arvensis (bindweed), limiting its flowering and seed production. Eriophyoid mites have advantages as biological control agents, including high host specificity, ability to reduce plant fitness, and rapid reproduction. However, their effectiveness can be impacted by environmental conditions, host plant resistance,
Eriophyoid Mites as Weed Biological Control Agenteidmk230
This document summarizes research on using eriophyoid mites as biological control agents for weeds. It discusses how eriophyoid mites can reduce weed fitness and competitiveness with crops. Several species of eriophyoid mites have been released and established to control specific weed targets, including Aceria chondrillae for skeleton weed, Aceria malherbae for field bindweed, and Aculus hyperici for St. John's wort. Factors that influence the potential of eriophyoid mites as biological control agents are also reviewed, as well as prospects for future research on identifying new mite species that could help control problematic native and invasive weeds.
This article examines how climate and herbivory have influenced the evolution of Senecio pterophorus, a plant native to South Africa that has invaded other regions. The study conducted a common garden experiment with populations from throughout the plant's native and introduced ranges, subjecting them to different watering treatments. It found that plants from introduced regions grew smaller and reproduced less than native plants, indicating genetic divergence related to climate differences rather than herbivory. Specifically, introduced plants adapted traits similar to native plants experiencing comparable drought conditions. The results suggest climate, not herbivory, has been the main driver of rapid evolution in S. pterophorus after invasion.
This document summarizes a credit seminar given by Zahid Abass Wazir on ecological engineering as a new direction for agricultural pest management. The seminar discusses ecological engineering as a habitat manipulation technique that focuses on reducing mortality of natural enemies to provide resources like nectar and pollen. It presents the advisory committee for Wazir's PhD, then introduces ecological engineering and its advantages over chemical pesticides. Mechanisms of top-down and bottom-up control are described, as well as ways to enhance natural diversity and design pest-stable agroecosystems through practices like increasing species and genetic diversity. Case studies demonstrating habitat manipulation techniques are also summarized.
This document summarizes a study on barriers to seedling regeneration in fire-damaged tropical peatlands in Brunei Darussalam. The study found that [1] competition from ferns and grasses, [2] lack of available seeds due to fire destruction, and [3] limited seed dispersal due to few resources attracting dispersers like birds and mammals were the main factors inhibiting natural regeneration. Controlling ferns and grasses through weeding, planting trees to attract dispersers, and applying assisted natural regeneration techniques can help overcome these barriers and accelerate the recovery of the native plant communities.

The document summarizes a study examining the impact of variable broadleaf density on spruce growth in northern British Columbia. The study established permanent and temporary sample plots across different sites to measure spruce growth under different broadleaf densities. Results showed that broadleaf competition was not as severe as previously thought, with spruce diameter and growth unaffected across a wide range of broadleaf densities. Higher broadleaf densities were found to provide structural diversity without significantly reducing spruce growth. The study concludes that current policies of removing broadleaf species are unnecessary and may reduce forest productivity and diversity.

This document summarizes a study on the impacts of chemical brushing (herbicide treatment) for forest vegetation management in British Columbia. The study examined effects on tree species diversity, growth, and white pine weevil attack. Key findings included higher stocking and growth of spruce trees in treated areas compared to untreated areas. Treated areas also experienced significantly greater white pine weevil attack. Species diversity of understory vegetation declined more over time in treated areas compared to untreated areas.
EcoSummit: Ecological Complexity and Sustainability, China 2007 Dr. Amalesh Dhar
The document compares the structural diversity and population characteristics of two English yew populations in Austrian gene conservation forests. It finds that population B has smaller and younger yews than population A, but with better overall vitality. Higher interspecific competition is associated with lower vitality for individual yews. Management recommendations include reducing interspecific competition through selective thinning to improve yew population viability long-term.
9th Student Conference for Conservation Science, UK 2008Dr. Amalesh Dhar
The document summarizes a study on the genetic structure of an Austrian relict population of English yew (Taxus baccata L.). A total of 2236 individual yews were observed with an average diameter at breast height of 8.8 cm. Isozyme analysis of 10 gene loci found 36 alleles and high genetic diversity, with an average of 3.4 alleles per locus and 90% polymorphic loci. Genetic parameters like expected and observed heterozygosity were estimated for the overall population and across different treatments, sexes, and other studies, showing generally high genetic variation in the population.

THE SACRIFICE HOW PRO-PALESTINE PROTESTS STUDENTS ARE SACRIFICING TO CHANGE T...indexPub
The recent surge in pro-Palestine student activism has prompted significant responses from universities, ranging from negotiations and divestment commitments to increased transparency about investments in companies supporting the war on Gaza. This activism has led to the cessation of student encampments but also highlighted the substantial sacrifices made by students, including academic disruptions and personal risks. The primary drivers of these protests are poor university administration, lack of transparency, and inadequate communication between officials and students. This study examines the profound emotional, psychological, and professional impacts on students engaged in pro-Palestine protests, focusing on Generation Z's (Gen-Z) activism dynamics. This paper explores the significant sacrifices made by these students and even the professors supporting the pro-Palestine movement, with a focus on recent global movements. Through an in-depth analysis of printed and electronic media, the study examines the impacts of these sacrifices on the academic and personal lives of those involved. The paper highlights examples from various universities, demonstrating student activism's long-term and short-term effects, including disciplinary actions, social backlash, and career implications. The researchers also explore the broader implications of student sacrifices. The findings reveal that these sacrifices are driven by a profound commitment to justice and human rights, and are influenced by the increasing availability of information, peer interactions, and personal convictions. The study also discusses the broader implications of this activism, comparing it to historical precedents and assessing its potential to influence policy and public opinion. The emotional and psychological toll on student activists is significant, but their sense of purpose and community support mitigates some of these challenges. However, the researchers call for acknowledging the broader Impact of these sacrifices on the future global movement of FreePalestine.

14. Materials and Methods – PVRM, Development of Management Strategies 16/04/10 Dhar et al. 2008 ecophysiological characteristics of yew commentes influence on disposition slow growth The slow growth of yew reduces the capabilities to compete with other neighbouring tree species for resources which suppress the overall growth and development (Thomas and Polwart 2003). ↑↑↑ vegetative regeneration- c apacity A high vegetative regeneration capacity helps yew to survive after severe damages of trunk and crown and increases the overall chances for natural recruitment as well (Suszka 1978, Dhar et al. 2006). ↓↓ hard resistant wood Yew is slight susceptibility against wood rottenness after stem damages ↓ weak needles The needles of yew are intolerant to severe and prolonged frost (Skorupski and Luxton 1998) and icy wind (Bugala 1978) and do not protect against high transpiration rates (Leuthold 1980, Zoller 1981). ↑↑ shade tolerance of juvenile plants Seedlings can survive in low light intensity up to few years after germination, but light is an important factor for its growth and survival in the years to follow (Krol 1978, Boratynski et al. 1997, Thomas and Polwart 2003, Iszkulo et al. 2005, Iszkulo and Boratynski, 2006)) ↓ shade tolerance of adult plants An adult yew can survive in unfavourable light conditions for a long time (Lilpop 1931, Krol 1978, Brzeziecki and Kienast 1994). ↓↓ resistance to fire and abiotic damages A high resistance to fire and the high vegetative regeneration-capacity allows yew to survive intensive abiotic damages (Gilman and Watson 1994) ↓ high drought tolerance The high drought tolerance allows yew to overcome severe shortcomings in water availability (Gilman and Watson 1994, Thomas and Polwart 2003) ↓ dioecious sexual system The major advantage of a dioecious sexual system is the reduction of the inbreeding depression (Darwin, 1876). High levels of heterozygoty might be found even in small populations. Disadvantages are the loss of fitness via one or other sex function and the lack of mobility which can lead to extinction of small populations on the other hand (Charlesworth, 2001). ↑ susceptibility to diseases, pest and biotic damages Diseases are not a major concern although yew is notably susceptible to Phytopthera sp. root diseases (Strouts 1993) and ramorum dieback ( P. ramorum ) (Lane et al. 2004). Thomas and Polwart 2003 noted that big bud mite ( Cecidophyopsis psilaspis Nalepa: Eriophyidae) considered as a serious pest of yew in northern and central Europe. However, Taxus mealybug, black vine weevil, Taxus scale and can cause some damages (Gilman and Watson 1994). ↑ wide physiological amplitude Yew has a wide physiological amplitude which allows yew to spread out on a wide range of sites (Thomas and Polwart 2003) ↓↓ susceptibility to browsing and grazing Kelly (1981) ,Haeggström (1990), Mysterud and Østbye (2004) and Dhar et al. (2006) reported that yew is very susceptible to browsing and Watt (1926) pointed out that grazing can drastically affect the net growth rates which leads to strong negative effects on recruitment and adult survival in deer populated areas. ↑↑↑ General Importance of Ecophysiological characterstics of English yew with regards to risk suceptibility and viability of a population ( ↑ ) increase disposition (risk of extinction) ; ( ↓ ) decrease disposition (risk of extinction)

A multi level approach is required to meet the demands of sustainable conservation strategies for yew populations in Austria During conservation planning an active participatory multi institutional involvement is needed to support local organizations in the implementation of forest conservation activities Public awareness programmes are needed to enhance the knowledge about the ecological importance of yew Continuous selective thinning will enhance the light availability which improves the population health condition for both pole stand and seedlings. Sound and professional harvesting operations is recommended which can reduce stem damages during tree felling The establishment of a fence in the studied gene conservation forests will help to observe the impacts of browsing on the regeneration. For studying natural population dynamics and long-term evolution the reproduction rate and sex ratio of the mature yew individuals has to be monitored More attention is needed for a better documentation of the role of birds and mammals that are responsible for seed dispersal T he regeneration status and the survival rate of yew individuals needs to be evalutated in 5-10 years cycles to allow sound recommendations for future conservation activities Further investigations are needed in other gene conservation forests in order to find the appropriate ecological requirements for the viability of yew populations in Austria It is necessary to investigate the optimum requirement of solar radiation for the seedling establishment which help to adapt the thinning activities accordingly . The Soil water relation is another important factor for reducing the survival rate of seedlings . So it should be checked. Investigations need to be extended in other gene conservation forests for assessing the regeneration status of yew all over the Austria. This will help to find out the actual causes about the shortcomings of certain height classes of seedlings. F urther investigations regarding the genetic structure are needed and more attention should be put on the number of samples as well as the sampling design Further investigations related to the possible impacts of climate change on different yew populations in Austria can help to enhance our understanding about the adaptation of the proper management activities for conserving the species
