Document Summary

In the news: emperor penguins in adelie land, antarctica, have been declining in numbers for the last 50 years. They are now about half as abundant as they were in the 1960s. Like all scientists, ecologists begin with observations in this case annual counts of penguins in one colony for 50 years. Next, ecologists suggest ideas to explain the observations and look for additional data to see if these ideas are correct. 1. 1 interaction between species determine where organisms live and how many live there: ecology scientific study of the interactions that determine the distribution and abundance of organisms some interactions are between diff species. Other interactions are between organisms and factors in the physical environment, including temp and precipitation: distribution where organisms are found, abundance how many organisms live in a given place. Distribution and abundance of many species vary in space: ecology and environmentalism. We are constrained by principles of ecology when we alter the environment.
