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..
What are examples of R selected species?
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.
What are the characteristics 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.
Are dogs k selected species?
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.
Are Lions K-selected?
Common examples of k-strategists species include humans, lions and whales.
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.
What are 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.
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 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 Wolves K strategist?
Potential for Infestation: Gray wolves exhibit the typical reproductive strategy of K-strategists. They are among the largest and longest lived canids with moderate litter size and significant parental/pack investment in raising the young.
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.
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.
What are the six characteristics of an R selected species?
These characteristics describe R-selected species perfectly:Rapid development.High reproductive rate.Early reproductive age.Small body size.One reproductive cycle.Short lifespan.Poor competitive ability.High mortality of offspring.More items…
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.
Why are invasive species R-selected?
Biologists characterize most invasive species as r-selected. … R-selected species often grow quickly and mature rapidly. Combined with their explosive reproductive potential, their quick growth and maturation allow them to colonize disturbed and early successional habitats remarkably well.
