Document Summary

Spatial scale (site to global) - the distance between habitat patches. Temporal scale (event to evolution) - habitat lifespan relative to the generation. Ecological time - a time scale (measuring changing environments) that we can directly observe. Ecosystem - species interacting in a given environment at given scale; at defined scale and scope. Impact on resources = per capita resource use x population size. Land transformation - we are approaching 50% land transformation on the planet. There is no place on the planet that is not affected by humans. Impact to biodiversity - we are in the driver"s seat" in changing the planet. Humans have impact on environment no matter what - we should try our best to minimize our impact. Sustainability - having enough resources to provide for our present needs and the needs of future generations. Underground economy - unrecorded and untaxed by government. Public sector - things that don"t make profit; infrastructure.

How does demographic and spatial structure modify the effects of the environmental stochasiticity on population dynamics?

How do spatial and temporal environmental heterogeneity influence diversity of all scales?

To what extent does diversity among primary producers drive diversity of the wider community?

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 Population Growth and Environmental Stability:

a) How does population size affect the resources used by a country?

b) How does population size affect other environmental conditions?

c) Are there other factors besides population size that can have an impact on resource consumption and environmental conditions in a country?
