Are humans R or K?
Both across and within species, r and K strategists differ in a suite of correlated characteristics.
Humans are the most K of all.
K’s supposedly have a longer gestation period, a higher birthweight, a more delayed sexual maturation, a lower sex drive, and a longer life..
Are cats K strategists?
Animals such as fish and frogs that lay hundreds of eggs at a time are R-strategists, animals such as humans, puffins and the majority of other organisms are K-strategists. The image shown shows a cat, an example of a organisms that produces few long living organisms.
Are dogs K or R strategists?
Indeed, one can think of a given organism as an “r-strategist” or a “K-strategist” only relative to some other organism; thus statements about r and K selection are invariably comparative. Cats and dogs are r-selected compared to humans, but K-selected compared to mice and rats.
What are the differences between R selected and K selected species?
r-selected babies grow rapidly, and tend to be found in less competitive, low quality environments. … K-selected species produce offspring that each have a higher probability of survival to maturity.
What is a feature of R selected species?
The production of numerous small offspring followed by exponential population growth is the defining characteristic of r-selected species. They require short gestation periods, mature quickly (and thus require little or no parental care), and possess short life spans.
Why are humans K selected species?
K-selected species possess relatively stable populations fluctuating near the carrying capacity of the environment. These species are characterized by having only a few offspring but investing high amounts of parental care. Elephants, humans, and bison are all k-selected species.
Is yeast an R selected or K selected species?
Expert Answer Yeast is an r-selected because they indicate high biotic factor and produce many offspring within a short time.
What is the difference between a K and R strategist species quizlet?
r-selected species are more common in this environment, along with disturbed communities. K-selected species are more common in this environment. Largest number of individuals of a population that an environment can support.
What is K strategist?
K-selected species, also called K-strategist, species whose populations fluctuate at or near the carrying capacity (K) of the environment in which they reside. … Such species produce a few large young instead of many small young.
Are K selected species generalists or specialists?
When environmental conditions change, generalists are able to adapt, but specialists tend to fall victim to extinction much more easily. K-Selected species are species that have a low intrinsic growth rate, which causes the population to increase slowly until it reaches the carrying capacity of the environment.
What is the difference between R and K selective provide an example of AK specialist species and an R specialist species?
The difference between R and K selective is the R selected species live in populations that are highly variable. K selected species live in populations that are at or near equilibrium for long periods of times. An example of a K selective species would be a Lion or Bear and a R selective species would be a fish.
Are trees R or K strategists?
For instance, trees have traits such as longevity and strong competitiveness that characterise them as K-strategists. In reproduction, however, trees typically produce thousands of offspring and disperse them widely, traits characteristic of r-strategists.
Are frogs K strategists?
Frogs produce many eggs, and a fraction live to reproduce themselves. They are an example of r-strategists. “r and K selection.” University of Miami: Department of Biology.
What animals are r-strategists?
Typical examples of r-species are mice, rabbits, weeds and bacteria, which have a lot of offspring, but a short life expectancy. Examples of organisms undergoing K-selection are tortoises, elephants, people, and sequoia trees: their offspring are few but long-lived.
Why r selected species tend to be opportunists?
Why do r-selected species tend to be opportunists? They reproduce and disperse rapidly when conditions are favorable or when disturbance opens up and a new habitat or niche for invasion. … They tend to reproduce later in life and have a small number of offspring with fairly long life spans.
