The linkages in a food web illustrate the feeding pathways, such as where heterotrophs obtain organic matter by feeding on autotrophs and other heterotrophs. The food web is a simplified illustration of the various methods of feeding that link an ecosystem into a unified system of exchange.
The relationship between ecosystem complexity and stability is a major topic of interest in ecology.Use of ecological networks makes it possible to analyze the effects of the network properties described above on the stability of an ecosystem.
A mechanical linkage is an assembly of systems connected so as to manage forces and movement. The movement of a body, or link, is studied using geometry so the link is considered to be rigid. [1] The connections between links are modeled as providing ideal movement, pure rotation or sliding for example, and are called
Food chain in a Swedish lake. Osprey feed on northern pike, which in turn feed on perch which eat bleak which eat crustaceans.. A food chain is a linear network of links in a food web, often starting with an autotroph (such as grass or algae), also called a producer, and typically ending at an apex predator (such as grizzly bears or killer whales), detritivore (such as earthworms and woodlice ...
In that example, cosegregation is being used to describe the linkage of data to each other in terms of the distance between specific windows in a genome. The values in the cosegregation matrix were found using the formula above. Comparing windows A and B, the formula seeks to find the intersection of Nuclear Profiles between the respective ...
In the context of genetic interaction networks, a genetic interaction is defined as "the difference between an experimentally measured double-mutant phenotype and an expected double-mutant phenotype, the latter of which is predicted from the combination of the single-mutant effects, assuming the mutations act independently. [1]"
Network science is an academic field which studies complex networks such as telecommunication networks, computer networks, biological networks, cognitive and semantic networks, and social networks, considering distinct elements or actors represented by nodes (or vertices) and the connections between the elements or actors as links (or edges).
In genetics, association mapping, also known as "linkage disequilibrium mapping", is a method of mapping quantitative trait loci (QTLs) that takes advantage of historic linkage disequilibrium to link phenotypes (observable characteristics) to genotypes (the genetic constitution of organisms), uncovering genetic associations.
