Are Plants R or K strategists?
Even plants are capable of r- and K-selected reproductive strategies.
Wind pollinated species produce much more pollin that insect pollinated ones, for example, because the pollin has to be carried at random by the wind to a receptive female flower.
Eggs too, can be r- or K-selected..
Are bacteria R-selected?
R-selected organisms, those emphasizing a fast growth rate, high number of offspring, include rabbits, bacteria, salmon, plants such as weeds and grasses, etc.
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.
Are oak trees K-selected?
Oak trees produce many offspring that do not receive parental care, but are considered K-selected species based on longevity and late maturation.
Are trees R-selected or K-selected?
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 rabbits K-selected species?
And yes rabbits. So if someone says a family breeds like rabbits that would be a “r” strategy – except in scientific terms people are K strategists. Conversely, K-selected species live in densities close to carrying capacity and are strong competitors with greater ability to be successful in adulthood.
What r-selected species?
R-selected species, also called r-strategist, species whose populations are governed by their biotic potential (maximum reproductive capacity, r). … Wilson; K-selected species—that is, species whose population sizes fluctuate at or near their carrying capacity (K)—make up the second strategy.
Are jellyfish R-selected?
r-selected species Animals that are r-selected do not give long-term parental care and the offspring are relatively mature and self-sufficient at birth. Examples of r-selected species are marine invertebrates, such as jellyfish, and plants, such as the dandelion.
Are Squirrels K-selected or R-selected?
Tree squirrels are K-selected compared to ground squirrels but rodents are r-selected compared to elephants, etc.
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.
Why are dandelions r-selected species?
Lesson Summary The R in R-selected represents population growth rate. Dandelions are particularly good examples of R-selected traits because they have several of the physical characteristics associated with R-selected traits including: rapid development, small size, and short lifespan.
Are tortoises k-selected?
Examples of organisms undergoing K-selection are tortoises, elephants, people, and sequoia trees: their offspring are few but long-lived. … K-selection, therefore, is selection for increasing control over the environment, whereas r-selection is caused by an environment that is intrinsically difficult to control.
Are oak trees R or K strategists?
This oak tree near my house is classified as a k-strategist because of it’s species survival strategies. The oak tree, like other k-strategists, develop in stable environments where their species population remains at stable numbers.
What are examples of K-selected species?
Examples of K-selected species include birds, larger mammals (such as elephants, horses, and primates), and larger plants.
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 Lions K-selected?
Common examples of k-strategists species include humans, lions and whales.
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.
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 trees K-selected?
K-selected species While larger in size when born, the offspring are relatively helpless and immature at birth. … Examples of K-selected species are primates including humans, other mammals such as elephants, and plants such as oak trees.
