Species selection in the broad sense—also termed species sorting—shapes evolutionary patterns through differences in speciation and extinction rates (and their net outcome, often termed the emergent fitness of clades) that arise by interaction of intrinsic biological traits with the environment. Effect-macroevolution occurs when those biotic traits, such as body size or fecundity, reside

Assessment of MPs in Oysters and Selected Species of Fish Adult slipper-shaped oysters, Crassostrea iredalei (locally called talaba), were obtained from an oyster hatchery located downstream of the Bombong estuary. These were cleaned on-site to remove debris and mud, wrapped in a cotton cloth, and carefully placed in Ziploc bags to prevent

parasites data and host genetic structure in the frame of a holistic approach for stock identification of selected Mediterranean Sea fish species - Volume 142 Issue 1 Species - Species - Speciation: Subspecies are groups at the first stage of speciation; individuals of different subspecies sometimes interbreed, but they produce many sterile male offspring. At the second stage are incipient species, or semispecies; individuals of these groups rarely interbreed, and all their male offspring are sterile. Natural selection separates incipient species into 2019-06-28 · Anthracnose of chili (Capsicum spp.) causes major production losses throughout Asia where chili plants are grown. A total of 260 Colletotrichum isolates, associated with necrotic lesions of chili leaves and fruit were collected from chili producing areas of Indonesia, Malaysia, Sri Lanka, Thailand and Taiwan. Colletotrichum truncatum was the most commonly isolated species from infected chili Sulaiman C T., Gopalakrishnan V K. Spectrophotometric determination of antioxidant potential of selected acacia species.

C selected species

A unit of selection is a biological entity within the hierarchy of biological organization that is subject to natural selection. There is debate among evolutionary biologists about the extent to which evolution has been shaped by selective pressures acting at these different levels. There is debate over the relative importance of the units themselves. For instance, is it group or individual selection that has driven the evolution of altruism? Where altruism reduces the fitness of Elephants are the classic example of a K-selected species and are joined in this classification by most other mammals, as well as most birds, some reptiles, and various hardwood trees. Mammalian MSC from selected species: Features and applications Cytometry A. 2018 Jan;93(1):32-49.

K-selected species tend to live in stable environments. They produce few offspring, that develop slowly and require a lot of care. They also tend to have long life spans. Also known as equilibrium species, or K-strategist. Compare this reproduction strategy to r-selected species, (AKA big bang reproduction and opportunistic species).

The key idea of r/K selection theory is that evolutionary pressures tend to drive animals in one of two directions — towards quickly reproducing animals whose specialty is to adopt as many niches as possible using simple strategies, and slowly rep The species that come under the class of K-selected species are called "K-strategists", and they can also be called K-selected. The examples of K-selected species are humans, elephants, whales, and trees. Organisms are generally distinguished as an R-selected species or a K-selected species.
