What are the differences between R and K strategists?
The key difference between r strategist and K strategist is that the r strategist lives in unstable and unpredictable environments while the K strategist lives in more stable environment.
Because of this environmental conditions, the r strategists produce many offspring while the K strategists produce few offsprings..
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 K-selected species opportunists?
Explanation: R-selected or opportunistic species are species that have high growth rates, produce many offspring, and have low survival odds for those many offspring. … Examples of k-selected species include mammals such as humans, dolphins, and rhinos.
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.
Why are rabbits R-selected?
So this begs the question are rabbits truly prolific, and why? In Page 2 the 1960s two ecologists came up with r/K selection theory. It relates to parental investment and reproductive strategies adopted by species in order to advance its kind into the future. … And they have the ability to reproduce rapidly.
Are Lions R or K selected?
Common examples of k-strategists species include humans, lions and whales.
Are humans R or K strategists?
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.
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.
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.
Why are endangered species k selected?
Endangered species are likely to be K-selected species because they produce fewer offspring and breed less frequently. They also have a later reproductive age and a low population growth rate.
Are cats R strategists?
r selected species are also known as r strategists and opportunistic species. They practice big-bang reproduction, AKA semelparity. … Cats are r-selected compared to humans, and K-selected compared to cockroaches.
Are birds r-selected species?
In this equation N is the number of individuals in the population, t is time, and r is the biotic potential. Examples of K-selected species include birds, larger mammals (such as elephants, horses, and primates), and larger plants.
Why are r-selected species 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.
Are weeds R-selected?
Examples of r-selected species include pest organisms, such as rodents, insects, and weeds.
What are 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.
What are some r selected species?
r-selected species are those that emphasize high growth rates, typically exploit less-crowded ecological niches, and produce many offspring, each of which has a relatively low probability of surviving to adulthood (i.e., high r, low K). A typical r species is the dandelion (genus Taraxacum).
Are turtles R or K-selected?
Plants such as dandelions are another good example of an r-selected species. … Sea turtles are a good example of a species that fits somewhere in the middle. The produce many eggs and do not care for their offspring once the eggs have been laid, but turtles live very long lives.
