81Metapopulation — A metapopulation consists of a group of spatially separated populations of the same species which interact at some level. The term metapopulation was coined by Richard Levins in 1970 to describe a model of population dynamics of insect pests in… …
82Detritus — For other uses, see Detritus (disambiguation). In biology, detritus is non living particulate organic material (as opposed to dissolved organic material). It typically includes the bodies or fragments of dead organisms as well as fecal material.… …
83Optimal foraging theory — Ants dismember a larger insect. Optimal foraging theory predicts these insects will forage in such a way as to maximize their colony s energy intake per unit time. Optimal foraging theory is an idea in ecology based on the study of foraging… …
84Plant defense against herbivory — Poison ivy produces urushiol to protect the plant from herbivores. In humans this chemical produces an allergic skin rash, known as urushiol induced contact dermatitis …
85Microbial loop — The microbial loop describes a trophic pathway in the marine microbial food web where dissolved organic carbon (DOC) is returned to higher trophic levels via the incorporation into bacterial biomass, and coupled with the classic food chain formed …
86Occupancy-abundance relationship — In macroecology, the occupancy abundance (O A) relationship is the relationship between the abundance of species and the size of their ranges within a region. This relationship is perhaps one of the most well documented relationships in… …
87Marine habitats — Coral reefs provide marine habitats for tube sponges, which in turn become marine habitats for fishes Littoral zone …
88Trophic level — First trophic level The plants in this image, and the algae and phytoplankton in the lake, are primary producers. They take nutrients from the soil or the water, and manufacture their own food by photosynthesis, using energy from the sun. The… …
89Niche apportionment models — Mechanistic models for niche apportionment are biological models used to explain relative species abundance distributions. These models describe how species break up resource pool in multi dimensional space, determining the distribution of… …
90Microbial cooperation — Microorganisms engage in a wide variety of social interactions, including cooperation. A cooperative behavior is one that benefits an individual (the recipient) other than the one performing the behavior (the actor).[1] This article outlines the… …
