91Mycotroph — A mycotroph is a plant that gets all or part of its carbon, water, and/or nutrient supply through symbiotic association with fungi. The term can refer to plants that engage in either of two distinct symbioses with fungi: Many mycotrophs have a… …
92Microbial metabolism — is the means by which a microbe obtains the energy and nutrients (e.g. carbon) it needs to live and reproduce. Microbes use many different types of metabolic strategies and species can often be differentiated from each other based on metabolic… …
93Lithoautotroph — 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… …
94Interspecific 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 …
95Mixotroph — 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 …
96Microbial 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… …
97Patch 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… …
98Mesotrophic 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… …
99Trophic 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 …
100Animal coloration — Chapman s Zebras in Botswana, displaying their outline disrupting camouflage Animal coloration has been a topic of interest and research in biology for well over a century. According to Charles Darwin s 1859 theory of natural selection,[1 …
