Are deer K-strategists?
Are deer K-strategists?
White-tailed deer show k-strategist characteristics because they have few young, compared to r-strategist, and they do provide parental care for the first year or so.
What animals are both R and K-selected?
For example, elephants are highly K-selected, whereas mice are much more r-selected. Among the fishes, most, like the salmon, are r-selected….r- and K-selection.
| Characteristic | r | K |
|---|---|---|
| Independence at birth | early | late |
| Ability to learn | low | high |
| Lifespan | short | long |
| Early mortality | high | low |
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 animals are r selected?
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 primates K selected or R selected?
Examples of K-selected species include birds, larger mammals (such as elephants, horses, and primates), and larger plants.
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.
Are turtles R or K-selected?
Many insects are r-selected. For example, ants can be considered r-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.
Are primates K-selected or r-selected?
What are the differences between r-selected and K-selected species?
The r selected species live in populations that are highly variable. The fittest individuals in these environments have many offspring and reproduce early. K selected species tend to have fewer offspring, so their populations cannot recover as fast from a disturbance such as over hunting or fire.
Are turtles R or K selected?
What is a 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.
