These cases all illustrate how different personality types of predators can select for . Biologists are often faced with the grim task of documenting the cascade effects of what happens when a species is removed from an ecosystem, by local extirpation or even extinction. Java Finch Nest Box, The designation "experimental wolves"* gives the people who manage wolf populations more freedom in decision making and gives the wolves less protection.

A keystone species is a species which has a disproportionately large effect on its natural environment relative to its abundance, a concept introduced in 1969 by the zoologist Robert T.

One very important phenomenon of trophic ecology is known as a trophic cascade, which describes the indirect control that a top predator exerts on species at lower, nonadjacent trophic levels. The organisms of a chain are classified into these levels on the basis of their feeding behaviour. Know the importance of food webs (predictive, describes trophic relations, illustrates effects on a population), and know the defenses and responses amongst plants and animals. The "top-down" or "bottom-up" refers to the ecological pyramid describing trophic levels. Diasend Clinic Sta len prepoji uvatesk et DEXCOM s pouvateskm tom Diasend, viac v nvode.
