Quick Answer: Are Mammals K-Selected?

Are elephants K strategists?

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.

Elephants are classic examples of K-selected species—that is, species characterized by relatively stable populations..

Are Grizzly Bears K-selected?

The grizzly bear (Ursus arctos ssp.) Elephants and bears though, also take K-selection reproduction very seriously. … Because of the immense dedication mother’s provide for their cubs, many of a bear’s advantageous traits are attributable to this K-selection type reproduction style.

Why are elephants K-selected species?

(a) Elephants are considered K-selected species as they live long, mature late, and provide long-term parental care to few offspring. Oak trees produce many offspring that do not receive parental care, but are considered K-selected species based on longevity and late maturation.

Are humans K selected species?

Elephants, humans, and bison are all k-selected species. … These species often have short life expectancies, produce as many offspring as they can, and invest very low amounts of parental care. R-selected species can include mosquitos, mice, and bacteria.

Are Tigers k selected?

Tigers are more K-selected when compared to leopards31 and should exhibit slower life history traits manifesting in slower population growth when compared to leopards.

Are deer K selected or R selected?

K- selected species are adapted to live in relatively stable habitats at or near carrying capacity (K) which is defined as the population size where births are exactly matched by deaths. … White-tailed deer are a K- selected species and most insects are r-selected species.

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 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 does R stand for in ecology?

The first variable is r (the intrinsic rate of natural increase in population size, density independent) and the second variable is K (the carrying capacity of a population, density dependent).

Are Lions R or K-selected?

Common examples of k-strategists species include humans, lions and whales.

What is 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 animals are K strategists?

Organisms whose life history is subject to K-selection are often referred to as K-strategists or K-selected. Organisms with K-selected traits include large organisms such as elephants, humans, and whales, but also smaller long-lived organisms such as Arctic terns, parrots and eagles.

Are cats r selected species?

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 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.

Why are rabbits r-selected species?

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.
