Question: Are Dandelions K-Selected Species?

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.
