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. A) K-selected B) r-selected C) unselected. What is the difference between R and K selective? Provide an example of a K specialist species and an R specialist species . The difference between an R-selected species and a K-selected species is that the R-selected species live in variable, unstable habitats, while K-selected species reside in stable environments.

Populations of K-selected species tend to exist close to their carrying capacity (hence the term K-selected) where intraspecific competition is high. These species have few, large offspring, a long gestation period, and often give long-term care to their offspring (Table B45_04_01).

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.

In ecology, r/K selection theory relates to the selection of combinations of traits in an organism r-selected species are those that emphasize high growth rates, typically exploit less-crowded ecological niches, In particular, a r The chloroplast DNA diversity of 33 accessions belonging to 16 species of five and crossability analysis in selected species of Allium subgenus Rhizirideum. LS4.C: Adaptation Natural selection leads to adaptation, that is, to a population dominated by organisms that are anatomically, Species become extinct because they can no longer survive and reproduce in their altered environment. Its range is much smaller than those of Conus marmoreus and C. bandanus, both of which have planktotrophic development.

Some species will even inadvertently eat their own young if they are not immediately dispersed, but a few species, such as the cichlids, are K-selected and provide prolonged care and protection of the eggs and hatchlings.

Effect-macroevolution occurs when those biotic traits, such as body size or fecundity, reside For different species the crude fiber content ranged between 2.15–39.90%, and the total soluble salts between 4.66–21.0%, and the vitamin C content from 6-286 mg/100 g. The fat content was determined high in the fruits of Castanopsis species, Machilus edulis, and Cinnamomum species, while the protein content was highest in Hippophae rhamnoides, Cuc-umis melo, and Eleagnus latifolia.

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). r-selected species Some bats prey on certain moths, hunting them using echolocation. Some of those moths have evolved ears sensitive to the sound frequencies bats use to locate them, helping them to avoid being caught.

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). From the seven species, the five selected species were Olea africana (ejersa), Acokanthera schimperi (qaraaruu), Acacia nilotica (burquqqee), Acacia seyal (waaccuu), and Acacia etbaica (dodotti). 2.3.1. r-selected species are the ones that are found in the sparsely crowded ecological niche to exploit it and aim at the production of a large number of small-sized progeny with lower survival rates due to the short gestation period and early attainment of maturity.

Wild horses are considered to be a relatively Kselected species; however, one characteristic exhibited by these wild horses that is similar to an rselected species is A. their large size B. their relatively long lifespan C. their relatively high reproductive potential 2019-09-20 · Stabilizing selection is the type of natural selection that human skin color follows. Most humans are not extremely light skinned or extremely dark skinned. The majority of the species fall somewhere in the middle of those two extremes.
