Are Lions K-selected?
Common examples of k-strategists species include humans, lions and whales..
Are humans K strategists?
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.
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.
Are humans specialists or generalists?
While H. sapiens are often highlighted as a classic example of a generalist species in this regard, local populations of our species are also able to specialize in the use of different food webs through time; hence, the generalist specialist.
Are pandas K-selected species?
Pandas fit the defining characteristics of a K-selected, or equilibrium, species. Female pandas carry their young for approximately 135 days, and only one or two panda cubs are born to a mother each year. … Pandas are usually solitary creatures, though their home ranges can overlap with one another.
Are K-selected species generalists or specialists?
When environmental conditions change, generalists are able to adapt, but specialists tend to fall victim to extinction much more easily. K-Selected species are species that have a low intrinsic growth rate, which causes the population to increase slowly until it reaches the carrying capacity of the environment.
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.
Are birds K strategists?
Examples of K-selected species include birds, larger mammals (such as elephants, horses, and primates), and larger plants.
What does R and K mean for population growth?
r, which is the growth rate of the population (how quickly or slowly it changes size) N, which is the number of individuals in that population; and finally. K, which is the carrying capacity, the maximum number of individuals that can be supported by the resources in a given area.
Are rabbits 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 K and R-selected species?
r-selection: On one extreme are the species that are highly r-selected. r is for reproduction. Such a species puts only a small investment of resources into each offspring, but produces many such low effort babies….r- and K-selection.CharacteristicrKLifespanshortlongEarly mortalityhighlow6 more rows
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 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.
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 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 song sparrows K strategists?
Song sparrows reproduce multiple times in a year and have limited parental care, traits of r-strategists. Generalists can live in a variety of habitats and have diverse diets.
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.
Why are endangered species k-selected?
Endangered species are likely to be K-selected species because they produce fewer offspring and breed less frequently. They also have a later reproductive age and a low population growth rate.
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.
Are Snakes r-selected species?
Despite having characteristics of both R and K strategists, Eastern Milk Snakes are R strategists. Mainly because of the fact that they do not care for their young, but also because the baby snakes mature fairly quickly.
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.
