Jan 6, 2021 Thus, K-selected individuals have been favored for their ability to make a large proportional contribution to a population that remains near that 

K-selected species have a few offspring that have a long life expectancy. For example, elephants are highly K-selected, whereas mice are much more r-selected. 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.

r- selected. An r-strategy is the strategy of an animal which breeds fast and produces numerous small offspring, but does not care for its offspring.

2020-04-23 The two evolutionary "strategies" are termed r-selection, for those species that produce many "cheap" offspring and live in unstable environments and K-selection for those species that produce few "expensive" offspring and live in stable environments. Their reproductive strategy is to grow slowly, live close to the carrying capacity of their habitat and produce a few progeny each with a high probability of survival.

Through this tutorial, you will use the Travel ti R-selected organisms, those emphasizing a fast growth rate, high number of offspring, include rabbits, bacteria, salmon, plants such as weeds and grasses, etc. The strategy for R-selected organisms includes producing a lot of offspring, producing them often, and having a relatively short lifespan. R-selected species usually don't care for offspring, whereas k-selected species such as 2017-11-06 · R-selected species can include mosquitos, mice, and bacteria. In terms of the American bison as a k-selected species, the gestation period for bison is 9.5 months or roughly 285 days---only five days longer than the gestation period for humans. Select vs.
