1) Climate change will affect on extinction of some species those are endemic, means those species that cannot accommodate the new environmental condition. In our ancient past dinosaurs like species got extinct because of climate change, so if such big species can get extinct then why not we.
2) Extinction will affect the food Web. Because in a food Web all are dependent on each other. If one will get affected then the other will also get affected. That's why the ecosystem can't be maintained and leading to the major extinction. Suppose due to climate change the plant community got extinct, that it will affect the herbivores animals.
Species extinction and habitat loss! Explain how Climate Change impads vulnerable species results in the spread...
Please answer all the questions not partly Q. 1 The number of species on the planet could be estimated by: Question 1 options choose one contrasting the background extinction rate to the modern extinction rate counting the number of dispersal and vicariance events comparing speciation rates to extinction rates considering the mutation rate and extent of genetic drift Q 2 All of the following are likely to cause mass extinction EXCEPT: Question 2 options:choose one many volcanoes erupt over a...
To determine how climate change and habitat loss will influence Antarctic species, baseline estimates of population sizes and distributions are needed. To this end, a group of researchers estimated the population sizes of all breeding colonies of emperor penguins (Aptenodytes fosteri) along Antarctic coastlines using satellite imagery (Fretwell et al., 2012). For each breeding colony encountered, the researchers determined the latitude, longitude, and area (m2) of the colony, and estimated the total number of emperor penguins present. Then, they compared...
Select a human-caused environmental issue (for example, climate change, species extinction, etc.) and research it further. Find a reliable, useful website that discusses the human impacts to the environment caused by this issue. Share the website by writing a full paragraph summary (150 words minimum) of what you have learned or have found particularly helpful when reviewing the website. This blog should be written in your own words. Include a link to the website.
Explain the problem of zebra mussels, and invasive species (see Case Study 11.1 in Natural Resource Conservation). Describe their spread in North America. Explain the environmental and economic problems associated with zebra mussels. What are some methods that are being used to control them? Identify a pathogen that has a significant impact on human health. What are its health effects? How is it spread? How might climate change or increased global connectivity (such as international travel) affect the spread of...
Explain how the concepts of social distancing and immunization are expected to influence the spread of COVID-19 and other infectious diseases, and how these processes help protect the vulnerable members of society. Explain how lack of participation by some members of society could affect these efforts.
Question 64. Earth has experienced five previous mass extinction events Many ecologists now believe we are experiencing a sixth mass extinction. How does this current mass extinction differ from previous extinction events? The background extinction rate now is much higher now than in previous a. extinction events b. The background rate of extinction is higher now than the rate of biodiversity so the current extinction event is more pronounced than previous ones. There are no differences in the previous and...
Please select a certain wetland type and based on your knowledge of climate change, what are the expected negative and positive changes to that wetland in regards to either #1 changes in vegetation, #2 hydrology and changes to flooding regime, #3 biogeochemical cycles or carbon storage, #4 changes in suitability as habitat for one rare animal species (e.g. lowland rattlesnakes in fens). PICK JUST 2 OF THESE 4 OPTIONS TO TALK ABOUT
Air pollution, Climate Change and Regulation [25] 1. Explain how climate change is related to air pollution? (5) 2. Why is air pollution metrology important and how is it used? (5) 3. Several laws and standards related to air pollution were provided in the presentation that address air pollution in various areas in the world. Discuss the relevance and context of air pollution and air quality standards in Namibia; also the effectiveness in addressing air pollution problems in Namibia (15)

Explain in one short paragraph how less reliable climate change forecasts of what will happen in the future cause less effort to reduce the impacts of climate change. 2. 3. Consider the impacts of using land for fruits and berries rather than a park. Turning the land into a park would lower benefits of these healthy foods for consumers by $10 million per year and that impact would last forever. (Assume farmers and other businesses would make equal profit...
Organism Consumer (1°or 2°) or Producer Herbivore, Omnivore, Carnivore, or Autotroph Bear Bison Camel Cat Cow Donkey Elephant Goat Hippo Horse Lion Rhino Tiger Great Goldfish Low Shrubs Verdigrass Dry Goatweed Plains Bushtail Grass Indigo Waterweed 1. How might the extinction of the dry goatweed cause a decline in the tiger population? 2. A pesticide is slowly leaked into the plains region. The plains bushgrass survives but contains trace amounts of the pesticide within it. Scientists find that the pesticide...
