An example of what a community ecologist would study is _____.
the interactions among several species of fish, the aquatic vegetation, and other animal species in the environment
Long-term data are valuable in assessing the health and stability of a community. Conservation biologists look for changes in a community over time to alert them to the fact that something is wrong with the community and that potential threats need to be assessed. Of particular importance to understanding community stability is the change in the ______.
number of species and their relative abundances in the community over multiple years
Disturbances to most communities, whether windstorms, floods, or the introduction of a new predator, are not uncommon. Community stability implies not so much the lack of change as the result of a disturbance, but rather the likelihood or ability to rebound from the disturbance. The disturbance-stability hypothesis states that species-rich communities will be more stable than species-poor communities because _______.
species-rich communities are more likely to have disturbance-resistant species that will increase in numbers in the face of a disturbance, compensating for disturbance-sensitive species that might decline in numbers temporarily
Whittaker concluded that most communities:
grade into each other continously.
_______ viewed communities as superorganisms.
Which of the following best describes a community?
an assemblage of many populations that live in the same place at the same time
