Document Summary

Ecology is just the study without the attachment of acting out on the case. Could have an evil ecologist use their knowledge to destroy the environment so its just a study without the attachment of activism. Ecological role or function some are redundant if you took one out, it would still function and look the same. Therefore every species doesn t necessarily play a role. Trade offs because of genetic/energy strains you can excel in one area but there will be a trade off with a downfall in another area good at one thing, bad at another. When we look at larger landscapes different ways at looking at problems scale influence observations. Embedded in the system are microorganisms which we can t see. Birds that migrate in and out of the system. (community consider all species) Landscapes areas that are different from each other forests/grasslands/streams throughout a forest or a desert. If you have predators will have a response (prey)

Prompt #3: Please provide very detailed information. Thank you.

Plants and animals do not operate independently of one another. In fact, it is how these organisms interact that often defines form and function. Ecology is the branch of biology that focuses on these species interactions with each other in the habitats that they live. In light of the many human-induced changes to the environment, it would be impossible to study ecology without accounting for anthropogenic effects. Assume you are an ecologist studying local flora and fauna in San Diego. Describe the effects of human development in a local habitat (e.g. coastal, desert, chaparral, grassland, wetland, etc.). How will continued global climate change effect species adapted to a specific environment? What conservation and management measures could be implemented to protect native species in San Diego?

Please Help. Thank you very much.

Ecology is the study of how organisms interact with their environment. Thus, a central question in ecology concerns how organisms respond to environmental variation. The flip side of this question is to ask whether the variation in characteristics of organisms is the result of variation in features of the environment. This variation can occur in space or through time.

1. Make a list of all the environmental variables that you can think of that are likely to be important to organisms. Think about plants and microbes as well as animals.

1A. One environmental change of great concern to us is climate change, specifically the prospect of human-caused global warming, a topic to which we will return. How do organisms respond to this spatial and temporal variability in the environment?

human activities are causing global climate change and human initiatives are needed to control it.the study of global climate change therefore belongs to the field of....because climate change......
a) ecology;is related to the locations of biogeographic regions
b)ecology;affects both land masses and oceans
c) environmentalism; involves scientific,ethical and policy issues
e) environmentalism;affects humans more than any other species
