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 ...
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]
The best-known example is the so-called "paradox of the plankton". [6] All plankton species live on a very limited number of resources, primarily solar energy and minerals dissolved in the water. According to the competitive exclusion principle, only a small number of plankton species should be able to coexist on these resources.
A free market does not directly require the existence of competition; however, it does require a framework that freely allows new market entrants. Hence, competition in a free market is a consequence of the conditions of a free market, including that market participants not be obstructed from following their profit motive .
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 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 ...
Example: Let α −2 = 0.451, α −1 = 0.5, and α 2 = 0.237. If α 1 = 0.5 then all eigenvalues are negative and the only attractor is a fixed point. If α 1 = 0.852 then the real part of one of the complex eigenvalue pair becomes positive and there is a strange attractor. The disappearance of this Lyapunov function coincides with a Hopf ...
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 ...
