Competition is an interaction between organisms or species in which both require one or more resources that are in limited supply (such as food, water, or territory). [1] Competition lowers the fitness of both organisms involved since the presence of one of the organisms always reduces the amount of the resource available to the other. [2]
In another example, competition between sugarbeet root aphid stem mothers for galling sites on the leaves of Populus angustifolia has also been shown to generally follow the Ideal Free Distribution. After hatching in the spring, female aphids compete with each other for galling sites closest to the stems of the largest leaves.
Ecological micro-succession and the competition-colonization trade-off in a bacterial meta-community on-chip.(A) sketch of a micron-scale structured bacterial environment based on microfluidics technology; (B) Fluorescent microscopy image of Escherichia coli (magenta) and Pseudomonas aeruginosa (green) inhabiting a device of the type depicted in A and which has been wettened with growth media ...
Competition is often for a resource such as food, water, or territory in limited supply, or for access to females for reproduction. [18] Competition among members of the same species is known as intraspecific competition , while competition between individuals of different species is known as interspecific competition .
Competition within, between, and among species is one of the most important forces in biology, especially in the field of ecology. [5]Competition between members of a species ("intraspecific") for resources such as food, water, territory, and sunlight may result in an increase in the frequency of a variant of the species best suited for survival and reproduction until its fixation within a ...
Developmental psychobiology posed this question since the lack of knowledge about the precise coordination of all cells, even those not related anatomically, in space and time during the embryonic period does not allow us to understand what forces at the cellular level coordinate four very general classes of tissue deformation, namely: tissue ...
For example, Trump’s EU trade threats resulted in the loss of hundreds of billions in U.S. agricultural exports from mid-2018 through the end of 2019, which necessitated government bailouts of ...
Scramble competition also exists in lepidopterans. For example, male mourning cloak butterflies will fly around in search for widely dispersed females. [12] Another example of scramble competition exists in Lactrodectus hesperus, the western black widow spider. There is a male-bias or skew within the sexually active population of this species ...
