Are Turtles K-Selected?

Are turtles K selected species?

It’s also important to note that not all K-selected species will have all the traits.

Sea turtles, for example, have long lifespans and slow development but produce and abandon many offspring, of which few survive.

In general, if a species demonstrates most of the traits, it can be classified as K-selected..

Are sea turtles R or K strategists?

Green Sea Turtles are both r and k strategists. They are k strategists because they live for a really long time and they are r strategists because they have a ton of babies then don’t stick around to take care of them.

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 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.

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?

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.

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.

Are rabbits R or K strategists?

In r and K selection theory, the rabbit is known as an r-strategist. R-strategists often live in unstable environments, so there’s little chance that their offspring would survive into adulthood.

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.

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.

What are K species?

K-selected species are characterized by long gestation periods lasting several months, slow maturation (and thus extended parental care), and long life spans. … Examples of K-selected species include birds, larger mammals (such as elephants, horses, and primates), and larger plants.

Which one is a K selected species?

Elephants, humans, and bison are all k-selected species. On the other hand, r-selected species often inhabit unstable environments and are completely density independent. These species often have short life expectancies, produce as many offspring as they can, and invest very low amounts of parental care.

What are K selected and R 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.

Are dandelions K-selected species?

Plants such as dandelions are another good example of an r-selected species. The r/k selection theory should be thought of as a spectrum. Some organisms may produce a medium number of offspring but those offspring still grow quickly and the parents provide little care.

Are Lions K-selected?

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

What animals are r strategists?

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.

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.
