population ecologyPopulationsökologie (ger.)

  • The study of the interaction of a particular species or genus population (or sometimes of a higher taxon) with its environment. (Oxford Dict. of Zoology 2009)

    The survival of adult bed-bugs, which had been fed once as adults and then set aside and starved, presents some interesting physiological problems partiularly those related to water loss and the role of water in the blood-meal. Such problems […] have no immediate bearing on the problems of population ecology.

    The population adds a level of complexity above that represented by the organism. Since it is composed of many organisms, it seems to follow that a population has certainorganismic attributes. In addition, however, it has a series of unique features, which emerge because it is a group-unit reacting as a whole within its effective en- vironment. It is this latter phase that particularly interests the student of population ecology.

    Both biometry and human demography have contributedsubstantially to population ecology.

    One special group of cases, where all the organisms are of one species, and all the organizing relations are intraspecific, can be abstracted from the community. These cases have proved to be of particular importance. The study of this group of cases is often referred to as population ecology
