Document Summary

The study of how organisms interact with each other and with their environment. Organismal: the study of individual organisms and their interaction with their environment (biotic and abiotic) Population: interactions between members of the same species with each other and their environment. Ecosystem: how communities interact with each other; how the system uses energy and recycles resources; interactions between communities and the climatic conditions of an entire region. Landscape: purposeful manipulation of landscape to provide organisms; effects of spatial distributions in an area that can affect a species. The environment: biotic components (the living portion, abiotic components (non-living portion, sunlight, temperature, rainfall (water), soil conditions, geography What is a population: three key characteristics, range geography/location, spacing pattern dispersion patterns, changes in size over time demography and population growth. Checks on populations: density independent factors, drought, freezes, floods, forest fires, storms, etc, pollution, rapid habitat loss, density dependent factors, disease, competition for resources, intraspecific and interspecific, predation, parasitism.

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?
