81Lithoautotroph — A lithoautotroph is a microbe which derives energy from reduced compounds of mineral origin. They may also be referred to as chemolithoautotrophs, a type of lithotrophs, reflecting their autotrophic metabolic pathways. Lithoautotrophs are… …
82Species 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… …
83Cline (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… …
84Interspecific competition — Interspecific competition, in ecology, is a form of competition in which individuals of different species compete for the same resource in an ecosystem (e.g. food or living space). The other form of competition is intraspecific competition, which …
85Mixotroph — A mixotroph is a microorganism that can use a mix of different sources of energy and carbon. Possible are alternations between photo and chemotrophy, between litho and organotrophy, between auto and heterotrophy or a combination of it. Mixotrophs …
86Microbial 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… …
87Mesopredator release hypothesis — Raccoons (Procyon lotor) and skunks (Mephitis mephitis) are mesopredators, here they share cat food in a suburban backyard. The mesopredator release hypothesis is a relatively new hypothesis from 1988[1] which describes the …
88Patch dynamics — For the use of the term in physics, see Patch dynamics (physics). Patch dynamics is a conceptual approach to ecosystem and habitat analysis that emphasizes dynamics of heterogeneity within a system (i.e. that each area of an ecosystem is made up… …
89Occupancy-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… …
90Mesotrophic soil — Mesotrophic soils are soils with a moderate inherent fertility. An indicator of soil fertility is its base status, which is expressed as a ratio relating the major nutrient cations (calcium, magnesium, potassium and sodium) found there to the… …
