This document summarizes the effects of invasive species on native flora and fauna. It discusses how some non-native species introduced by humans become established and negatively impact biodiversity by outcompeting native plants and animals for resources. Specific examples are given of how invasive plants like Japanese honeysuckle and gamba grass can inhibit the reproduction of native species, increase fuel loads and fire intensity, and alter ecosystem properties by increasing soil nitrogen. The economic and ecological impacts of invasive species like rhododendron and Himalayan balsam are also discussed.

Endangered species are at risk of extinction due to threats like habitat loss, hunting, and climate change. Conservation aims to protect biodiversity by preserving habitats, restoring degraded areas, and protecting species. Some common conservation actions include habitat preservation, restoration, captive breeding programs, anti-poaching measures, and wildlife corridors. Individuals can help endangered species by reducing their environmental impact, supporting conservation organizations, and volunteering.
Invasive species finished_epic
Non-native species that are introduced to areas outside of their natural habitat can have negative environmental, economic, and ecological impacts if they disrupt the native ecosystem. They may compete with native species for resources, prey on native species, spread diseases, or cause native species to decline or go extinct. Some invasive species that are discussed include the coypu which has damaged riverbanks in Italy, and the Asian tiger mosquito which can transmit diseases and displace other mosquito species. Efforts to prevent, control, and eradicate invasive species face challenges due to their ability to spread widely.

This document discusses several ways that humans negatively impact the environment, including habitat destruction, invasive species, population growth, pollution, and overuse of resources. It provides examples of each using the cheetah as a mascot species. Habitat destruction from deforestation, development, and fragmentation has reduced areas cheetahs can live. Invasive species like humans threaten cheetahs through conflicts and poaching. Large human populations stress resources and contribute to other issues like pollution. The examples show how climate change, water and air pollution, and over-hunting of cheetah prey due to human overuse of resources all threaten cheetah survival.

Invasive species are often introduced by human actions and can harm ecosystems by disrupting native species, altering processes, and introducing diseases. They can also negatively impact economies by reducing land values and causing economic losses. Prevention efforts include restricting intentional introductions and early detection of new invaders.
Invasive impact of prosopis juliflora on wildlife conservation and livelihoods
Impact of Prosopis julifora on Conservation of Biodiversity and Livelihoods.
Invasive species are flora and fauna whose introduction into a habitat disrupts the native eco-system. P. juliflora is a shrub or small tree native to Mexico, Central and northern South America. It has shown itself to be a very competitive invader, notably in frost-free arid and semi-arid natural grasslands, both in its native country and in particular, where it is introduced. Prosopis as a genus is treated as one of the world's most detrimental invasive plant species, and P. juliflora is by far the common invasive species. This has led to the proclamation of P. juliflora as an invasive and/or deleterious weed in many African countries notably Ethiopia and Sudan, Pakistan and other Asian countries, Australia and also in South Africa. In further sub-tropical regions such as in Australia and southern Africa, however, it is much less prevalent than additional invasive Prosopis species such as P. glandulosa and P. velutina (the Invasive Species Compendium, also P. pallida with which P. juliflora is often confused). P. juliflora was extensively introduced and planted as a fuel and fodder species, particular during fuelwood programmes in the 1980s, and the seed is spread widely by grazing, wild animals and humans too.
An analysis of the International Union for the Conservation of Nature Red List refers to invasive species as the second most common threat associated with species that have gone completely extinct, and are the most common threat associated with extinctions of amphibians, reptiles and mammals. Majority of endangered wild animals risk projected extinction in coming years through adverse effects caused by Prosopis juliflora. It is a nitrogen-fixing and very drought and salt-tolerant species, which can rapidly out-compete other vegetation. The thorniness and bushy habit of P. juliflora enable it to quickly block paths and make whole areas impenetrable. The specie poses diverse adverse effects to animals as well as endangered wildlife, and sensitization about conservation should be enacted.
Edangered species
An endangered species is a species facing a high risk of extinction. There are currently over 3070 endangered animal species and 2655 endangered plant species worldwide. The main cause of species endangerment and extinction is habitat destruction and fragmentation due to human activities like pollution, deforestation, and destruction of coral reefs. When a species goes extinct it can disrupt the balance of the entire ecosystem. International efforts aim to protect endangered species through conservation programs and biodiversity action plans.

Ecological succession is the process by which the species composition or community structure of an ecosystem changes over time. There are two main types of succession - primary and secondary. Primary succession occurs on new surfaces without soil, such as after a volcanic eruption. Secondary succession occurs in areas that were previously inhabited but have been disturbed. Succession proceeds from simple to more complex communities and ends with a stable climax community. Factors that threaten biodiversity include habitat loss, poaching, human-wildlife conflict, invasive species, and climate change. Conservation efforts include protected areas for in-situ conservation and zoos/botanical gardens for ex-situ conservation.
Biodiversity presentation on conservation of nature and natural resoures
Habitat destruction, invasive species, overexploitation, and climate change are major threats to biodiversity. Habitat destruction occurs through direct destruction of habitats by human activities like bulldozing, as well as fragmentation and degradation of habitats. Invasive species harm native ecosystems through competition, predation, and disease. Overexploitation of resources like forests and fish stocks can diminish populations. Climate change is altering ecosystems and causing many species to become extinct as they struggle to adapt to new conditions. Collectively, these human-driven changes are occurring at a rate that is 100 times greater than normal background rates of extinction.

En danger and treatened
This document discusses endangered and threatened species in the Philippines. It outlines several major threats to biodiversity like habitat loss, introduction of invasive species, overhunting, climate change, and more. Certain characteristics make species more vulnerable to endangerment, like large size, specialized diets/habitats, low reproduction rates, and small population sizes. Endemic and rare species are at high risk due to limited distributions. The document reviews criteria used by IUCN to evaluate endangered species status and lists numbers of threatened species in the Philippines according to these criteria.
Departmental endangered species
1) An endangered species is a group of animals, plants, or other organisms that is at high risk of extinction due to factors such as hunting, habitat loss, climate change, and pollution.
2) Many medicinal plants in India have become endangered due to overcollection for domestic and international markets. The IUCN added 44 Indian medicinal plants to its Red List in 2015, with 18 classified as vulnerable, 16 as endangered, and 10 as critically endangered.
3) Key reasons for threats to these medicinal plants include habitat loss and degradation, illegal trade, overexploitation, overgrazing, human settlements, and climate disasters. Conservation efforts are needed like sustainable collection practices, habitat management, and monitoring populations

Threats to biodiversity
1) Estimates of total global biodiversity vary considerably due to limitations in scientific research, but the current rate of species loss is far greater than historically due to human activities like habitat destruction and pollution.
2) Key drivers of species extinction include habitat loss, invasive species, pollution, overharvesting, and human-caused climate change. Tropical regions face particular threats due to conflicts between conservation and economic development.
3) Maintaining biodiversity requires preserving complex, functioning ecosystems and limiting human-driven factors like the introduction of diseases, agricultural practices, overpopulation and overexploitation of natural resources.
Biodiversity 2009
Biodiversity and sustainable development are interdependent. Biodiversity refers to the variety of life on Earth at genetic, species, and ecosystem levels. It is being lost at an unprecedented rate due to factors like poverty, population growth, poor agricultural practices, pollution, and energy crises. Key threats in Tanzania include ecological isolation of protected areas, habitat fragmentation, unsustainable food and timber production, and invasion by exotic species. Conservation efforts aim to protect biodiversity hotspots with high numbers of endemic and threatened species through establishing protected areas and alternative livelihood programs.
genitics of antibody diversity
This document discusses the genetics of antibody diversity. It describes three main mechanisms that generate antibody diversity: somatic recombination, somatic hypermutation, and class switching. Somatic recombination involves randomly combining variable, diversity, and joining gene segments to generate a wide variety of antibody sequences. Somatic hypermutation further introduces random mutations during B cell activation, allowing higher affinity antibodies to be selected. Class switching changes the constant region of the antibody to alter effector functions. These three processes together allow the immune system to generate a vast repertoire of antibodies with unique specificities.

Indian philosophy posits three states of consciousness: waking, dreaming, and deep sleep. These states correspond to the gross, subtle, and causal bodies respectively. Several ancient Upanishads discuss states of consciousness including awake, dream-filled sleep, deep sleep, and beyond deep sleep. There are four types of brain waves - beta, alpha, theta, and delta - which occur during different stages of wakefulness and sleep. Sleep stages progress from light to deep sleep, consisting of NREM stages 1-3 and REM sleep. Neurotransmitters like acetylcholine and hormones like melatonin regulate the sleep-wake cycle which is controlled by the circadian rhythm in the hypothalamus. DNA repair occurs more during sleep, reducing

MEMORY.pptx
Memory is the faculty of encoding, storing, and retrieving information over time. There are three main stages of memory: sensory memory (lasting seconds), short-term memory (lasting minutes), and long-term memory (lasting a lifetime). Information moves from sensory to short-term memory and can be consolidated into long-term memory through rehearsal. There are two main types of long-term memory: declarative memory involving facts and episodic memory involving personal experiences. Memory disorders like amnesia can cause inability to form new memories or recall past events due to brain injury, disease, or other causes.
Social Behaviour of Insects - Archit KS@DEI.pptx
The document discusses the social behavior of insects. It provides examples of different types of social behaviors seen in insects, from solitary and aggregating behaviors to highly advanced eusocial behaviors with division of labor. Specific behaviors discussed include cooperative hunting, trophallaxis, altruism, nest construction, and more. Examples are given of advanced eusocial insect societies like ants, bees, and termites that live in colonies with castes and cooperative care of young.
muscle7-smoothmuscle-180414110808.pptx
- Smooth muscle fibers are much smaller in diameter and length compared to skeletal muscle fibers. Smooth muscle lacks striations and is located within organs like the intestines and blood vessels.
- Smooth muscle contraction is initiated by an increase in intracellular calcium ions which can be triggered by nerve stimulation, hormones, stretch of the fiber, or chemical changes. Calcium then binds to calmodulin instead of troponin to drive contraction.
- Smooth muscle exhibits a slow cycling of myosin cross-bridges, requiring less energy for sustained contraction compared to skeletal muscle. Its contraction and relaxation is also slower than skeletal muscle.
Protein protein interactions.pptx
Protein-protein interactions (PPIs) are physical contacts between two or more proteins that allow them to perform biological functions. PPIs are stabilized by covalent or non-covalent forces and often involve proteins with specific quaternary structures. Examples of PPIs include muscle contraction mediated by actin, myosin, and other proteins, as well as biosignaling pathways. PPIs can be studied experimentally using methods like yeast two-hybrid systems, fluorescence resonance energy transfer, and affinity chromatography, or computationally using protein interaction databases. Understanding PPIs is important for developing new drugs that target protein interactions.
chemical capturing anisha.pptx
This document summarizes methods for capturing wild animals, including physical restraint and chemical immobilization. Physical restraint involves traps, nets, and snares, but requires extensive planning and can stress animals. Chemical immobilization uses anesthetic drugs administered remotely via darts or jab sticks. It allows targeting specific animals and is cheaper than physical restraint. Factors like species, age, weight, sex affect drug doses. Common drugs are tranquilizers, sedatives, and CNS depressants. Routes include oral, injection via syringe or dart. The shoulder and hindquarters are preferred darting sites. Proper drug doses require knowing the animal's weight, drug concentration, and recommended dosage.
indudsrtial solvent.pptx
Industrial solvents are chemicals that dissolve other substances without chemically changing them. They are widely used to remove solids, grease, and other materials. Solvents can be organic, containing carbon, or non-organic. Common industrial solvents include alcohols, chlorinated hydrocarbons, and hydrocarbons. They are used in applications like pharmaceuticals, cosmetics, agrochemicals, paints, cleaners, and inks. Proper ventilation and protective equipment are important when working with solvents due to their toxicity.
thecausesofclimatechange-141020085111-conversion-gate02 (2).pptx
This document discusses both human and natural causes of climate change. On the human side, it outlines how increased population leads to more methane from livestock and more carbon dioxide from burning fossil fuels for energy and from deforestation. Volcanic eruptions and variations in the sun's output are presented as natural influences on climate. The effects of climate change are explained as occurring across short, medium, and long timescales.
uv visible spectroscopy.pptx
UV-visible spectroscopy involves measuring the absorption of electromagnetic radiation in the ultraviolet-visible spectral region. It works on the principle that molecules undergo electronic transitions when exposed to UV-visible light, absorbing different wavelengths depending on their structure. The absorbed wavelengths are recorded as peaks in a spectrum, which can be used to identify molecules. Common applications include quantitative and qualitative analysis of samples, determination of molecular structure, and measurement of reaction kinetics.
mi%20rna%20%20FINAL.pptx
This document discusses microRNAs (miRNAs), which are small non-coding RNA molecules involved in post-transcriptional gene regulation. It describes the history of miRNA discovery, their location in plants, animals and some viruses. The structure and biogenesis of miRNAs is explained, from transcription of miRNA genes, nuclear processing to form hairpin pre-miRNAs, export from the nucleus, cytoplasmic processing by the enzyme Dicer, and loading into the RNA-induced silencing complex (RISC) where they regulate mRNAs.
centrifugation.pptx
Centrifugation uses centrifugal force to separate particles in a solution based on properties like size, shape, density. During centrifugation, a centrifuge spins the samples at high speeds, applying centrifugal force that causes more dense components to sediment away from the axis of rotation while less dense components migrate towards the axis. Different types of centrifuges exist for various applications, utilizing rotors that hold sample tubes at fixed angles or allow swinging buckets. Centrifugation is used across industries and in research/medical labs for tasks like separating blood components, purifying proteins and organelles, and producing density gradients for analytical separations.

EWOCS-I: The catalog of X-ray sources in Westerlund 1 from the Extended Weste...
Context. With a mass exceeding several 104 M⊙ and a rich and dense population of massive stars, supermassive young star clusters
represent the most massive star-forming environment that is dominated by the feedback from massive stars and gravitational interactions
among stars.
Aims. In this paper we present the Extended Westerlund 1 and 2 Open Clusters Survey (EWOCS) project, which aims to investigate
the influence of the starburst environment on the formation of stars and planets, and on the evolution of both low and high mass stars.
The primary targets of this project are Westerlund 1 and 2, the closest supermassive star clusters to the Sun.
Methods. The project is based primarily on recent observations conducted with the Chandra and JWST observatories. Specifically,
the Chandra survey of Westerlund 1 consists of 36 new ACIS-I observations, nearly co-pointed, for a total exposure time of 1 Msec.
Additionally, we included 8 archival Chandra/ACIS-S observations. This paper presents the resulting catalog of X-ray sources within
and around Westerlund 1. Sources were detected by combining various existing methods, and photon extraction and source validation
were carried out using the ACIS-Extract software.
Results. The EWOCS X-ray catalog comprises 5963 validated sources out of the 9420 initially provided to ACIS-Extract, reaching a
photon flux threshold of approximately 2 × 10−8 photons cm−2
s
−1
. The X-ray sources exhibit a highly concentrated spatial distribution,
with 1075 sources located within the central 1 arcmin. We have successfully detected X-ray emissions from 126 out of the 166 known
massive stars of the cluster, and we have collected over 71 000 photons from the magnetar CXO J164710.20-455217.

The technology uses reclaimed CO₂ as the dyeing medium in a closed loop process. When pressurized, CO₂ becomes supercritical (SC-CO₂). In this state CO₂ has a very high solvent power, allowing the dye to dissolve easily.
The binding of cosmological structures by massless topological defects
Assuming spherical symmetry and weak field, it is shown that if one solves the Poisson equation or the Einstein field
equations sourced by a topological defect, i.e. a singularity of a very specific form, the result is a localized gravitational
field capable of driving flat rotation (i.e. Keplerian circular orbits at a constant speed for all radii) of test masses on a thin
spherical shell without any underlying mass. Moreover, a large-scale structure which exploits this solution by assembling
concentrically a number of such topological defects can establish a flat stellar or galactic rotation curve, and can also deflect
light in the same manner as an equipotential (isothermal) sphere. Thus, the need for dark matter or modified gravity theory is
mitigated, at least in part.

- 1. Effect of Invasive species on Flora and Fauna. Presented By-Anjali Rajput M.Sc.(ZOO) 2204633 Seminar / (G.D.) Presentation on Zom801- Wildlife Techniques
- 2. What is the issue? ● Alien or non-native or invasive species are animals, plants or other organisms introduced by humans and other means, either intentionally or accidentally, into areas outside their natural range. ● Some of these species become established and negatively impact native biodiversity.
- 3. Introduction ● Plasticity and local adaptation leads to greater invasiveness.
- 4. Outline of Effect of invasive species
- 5. Effect on Species and Communities ● Lonicera japonica (Japanese honeysuckle) inhibited the reproduction of dominant forest trees such as Liriodendron tulipifera (tulip poplar), Prunus serotina (wild black cherry)
- 6. Effect on Ecosystem Properties ● In the Wildman Reserve in northern Australia, invasion of Andropogon gayanus (gamba grass) increased fuels loads by up to seven times, and increased fire intensity by up to eight times compared to areas with native grasses
- 7. Effect on Biogeochemistry and Ecosystem Dynamics ● In Hawaii Volcanoes NP, nitrogen-fixing species (Morella faya and M. cereifera) significantly increase soil nitrogen availability, by up to 400 %. These changes resulted in altered succession trajectories
- 8. Effect on Ecosystem Services ● Under Millennium Ecosystem Assessment :- ● Provisioning - genetic resources ● Regulating- governing functions ● Cultural services.--cultural heritage, recreation/tourism, aesthetic values,
- 9. Effect on Economic Impact ● The costs of controlling Rhododendron ponticum (rhododendron) invasion in the Snowdonia NP, Wales, was estimated to be £45 million . ● Impatiens glandulifera (Himalayan balsam) is an annual plant native to Asia currently invasive in many protected areas in Europe Introduced as a garden ornamental and still frequently planted, it spreads into semi-natural plant communities along water courses.
- 10. Other impacts :- ● Resource competition– with introduced water hyacinth from S. America ● Predation– introduced Nile perch drove hundreds of cichlid fishes extinct ● Parasitism– South Pacific snail Partula turigida driven extinct following infection with microsporidian parasite called Steinhausia. ● Disease transmission– Dutch elm disease (beetle transmitted fungus Ophiostoma ulmi, that kills American elm) ● HIV in humans. Etc
