Abundance (ecology)

from Wikipedia, the free encyclopedia

The abundance (from Latin abundantia = abundance, adjective abundant ), also density , frequency or degree of quantity , describes in ecology the number of individuals of a species , based on their habitat . You can be in absolute number of there settled or residing mean species. The population density can be equated with the abundance as soon as the considered area or spatial unit corresponds to the settlement area.

The abundance rule states that in ecosystems with a wide range of features, the species with a large response range achieve the greatest abundance. In contrast, in poorly equipped ecosystems, species that have a smaller, but more specific response range, achieve a lower abundance.
