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

2020-04-08 · The K-selected species are larger in size, reach sexual maturity later in life, reproduce many times during their life span and require more energy to procreate. Whales, giraffes and elephants are examples of K-selected species.

K-strategy  c. r-selected and K-selected species use similar reproductive strategies but r- selected species require less energy to reproduce than K-selected species. Solved: An r-selected species characteristically has (a) a type I survivorship curve . (b) few offspring. (c) a population near carrying capacity. (d) significant  In order to grow, the cells must combine the resources into a third metabolite.

Among the fishes, most, like the salmon, are r-selected. 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. Proper chromatographic methods may reduce the challenges inherent in analyzing natural product extracts, especially when utilizing hyphenated detection techniques involving mass spectrometry. As there are many variations one can introduce during chromatographic method development, this can become a daunting and time-consuming task.

Temporary no-take zones are increasingly introduced in Sweden as a fisheries management tool to restore populations of specific target species. A paper 

This strategy is often employed in unpredictable or changing environments. Animals that are r-selected do not give long-term parental care and the offspring are relatively mature and self-sufficient at birth.

Our proposals are supported by phylogenetic analyses, DNA G+C content, and reclassification of selected species within the genus Propionibacterium to the

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. Examples of k selected species are elephants, horses, gorillas, and humans.
