Chapter 54 - Community Ecology

Community ecology

________ provides a framework for identifying important species interactions associated with such diseases, as well as for tracking and controlling their spread.

Mutualism

________ is a + /+ relationship since both species rely on one other for life and reproduction.

Disturbance

________ has an impact on species diversity and composition.

Climate

________ has an impact on the diversity gradient via energy (heat and light) and water.

exclusion states

Competitive ________ that two species vying for the same resource can not live in the same location indefinitely.

Pathogens

________ change the structure of communities both locally and internationally.

Biological communities

________ are distinguished by their diversity and trophic structure.

series of community

The ________ and ecosystem changes following a disturbance is referred to as ecological succession.

Commensalism

________ refers to a relationship between species that benefits one but neither damages nor helps the other (+ /0)

trophic structure

The ________ is an important aspect of community dynamics.

Zoonotic pathogens

________ are infections that spread from animals to people and are responsible for the majority of developing human illnesses.

Interspecific interactions

________ have an impact on survival as well as the reproduction of the species that participate in them.

Geospiza fuliginosa

________ and Geospiza fortis allopatric populations on Los Hermanos and Daphne Islands exhibit comparable beak morphology (top two graphs) and probably consume similarly sized seeds.

Keystone species

________ are often low- abundance species that have a disproportionate impact on community structure.

mutualism

Commensalisms, like ________, are widespread in nature.

Pathogens

________ have an important influence on the structure of terrestrial and marine ecosystems, according to recent research.
