81Species-area curve — The species area relationship for a contiguous habitat In ecology, a species area curve is a relationship between the area of a habitat, or of part of a habitat, and the number of species found within that area. Larger areas tend to contain… …
82Microbial intelligence — (popularly known as bacterial intelligence) is the intelligence shown by microorganisms. The concept encompasses complex adaptive behaviour shown by single cells, and altruistic and/or cooperative behavior in populations of like or unlike cells… …
83Species distribution — A species range maps represents the geographical region where individuals of a species can be found. This is a range map of Juniperus communis, the common juniper. Species distribution is the manner in which a biological taxon is spatially… …
84Cline (biology) — In biology, an ecocline or simply cline (Greek: κλίνω = to possess or exhibit gradient, to lean) describes an ecotone in which a series of biocommunities display continuous gradient.[1] The term was coined by the English evolutionary biologist… …
85Microbial food web — The microbial food web refers the combined trophic interactions among microbes in aquatic environments. These microbes include viruses, bacteria, algae, heterotrophic protists (such as ciliates and flagellates). In aquatic environments, microbes… …
86Trophic state index — The quantities of nitrogen, phosphorus, and other biologically useful nutrients are the primary determinants of a body of water s trophic state index (TSI). Nutrients such as nitrogen and phosphorus tend to be limiting resources in standing water …

89Environmental niche modelling — Environmental niche modelling, alternatively known as species distribution modelling, (ecological) niche modelling, and climate envelope modelling refers to the process of using computer algorithms to predict the distribution of species in… …
90Commensalism — A titan triggerfish (Balistoides viridescens) creates feeding opportunities for smaller fish by moving large rocks too big for them to shift themselves. In ecology, commensalism is a class of relationship between two organisms where one organism… …
