The Scope of Ecological Research Ecologists work at levels ranging from individual organisms to the planet Questions asked by Ecologist Why are orangutans restricted to forests in Borneo and why are they rapidly declining? How to create a mathematical model to predict how HIV virus will increase in India? How long will it take for the current human population of 6.6 billion to double? what are the best policies for managing our environmental support systems -- our watersheds, agricultural lands, wetlands

Organismal Ecology Organismal ecologists explore the morphological, physiological, and behavioral adaptations that allow individual organisms to live successfully in a particular area.

Organismal ecologists study morphological, physiological, and behavioral adaptations a. Behavioral studies can reveal how an individual responds to stimuli in its environment. b. Physiological studies can reveal how individuals thrive in the changing conditions of their environment. An example of Organismal ecology: Sockeye Salmon breeding Scientists are interested in studying Salmon breeding habits, traits that make them reproductively successful, and this information will help them survive the changing environment

Population Ecology A population is a group of individuals of the same species that lives in the same area at the same time. Focus is on processes of birth and death, immigration and emigration , influenced by: the physical environment interactions with other populations •What environmental factors affect the reproductive rate of wild bison?
