Is Miami blue butterfly K-selected or R-selected?
K selected
What is the difference between r selected and k selected species?
R- Selected species have high population densities while k-selected species have lower population densities
Is a sperm whale r-selected or k-selected species?
K-selected
Are vultures r selected or k selected?
Vultures are k-selected organisms because they only have a few offspring, they take care of their offspring, and they do not reproduce quickly.
How can a stressful environment alter the standard r-selection and k-selection?
1. What is the difference between r-selected and k-selected organism? Which strategy would you expect to be more prevalent in unpredictable environments (high stochastic variation in conditions)?
What is the difference between r selected and K selected species populations?
Those are reproductive strategies that identify certain species. R-selected are those that reproduce rapidly and produce a lot of progeny; bacteria are an example. K-selected are those that reproduce very slowly and are slow to mature; humans are a k-selected species. Population density is the number of organisms per unit area. Some organisms don' t like to be crowded, so the density can affect the population size. Also, some limiting factors are density-dependent, like food or living space.
Are frogs r or K selected organisms?
frogs are r-selected because they produce many offspring but only a few of them survive. There is no parental investment and they become reproductively active early in their life cycle.
What do you mean by 'r' and 'k' selection differentiate?
The r and K selection theory refers to two different reproductive strategies in ecology. r-selected species typically have many offspring, grow quickly, and have a high reproductive rate. K-selected species have fewer offspring, invest more resources in each offspring, and have a lower reproductive rate. These strategies are shaped by different environmental conditions and life history traits.
What are the are characteristics of K-selected species?
K-selected species are present in environments that are predictable and where resources aren't necessarily fought over. A k-selected species will produce less frequently and with few children than an R (or S) selected species. It's the concept of quality over quantity. K-selected species are typically bigger, take longer to reach maturity, and live longer.
Are snakes r selected species or k selected species?
Snakes display both r and K traits. They are much longer lived, produce a moderate number of eggs (some species far fewer than others). The issue with the r/K equation is that there are too many species that have the characteristics of both the r and K types which renders the information either obvious...like humans being a definite K to some frogs that are definitely r...or with some calculated value that is essentially too general for use.
When was Selected Stories of Philip K. Dick created?
Selected Stories of Philip K. Dick was created in 2002.
Are lizards r strategists or k strategists?
R-selected. They produce many offspring, are weak competitors in crowded niches, and are usually of small body size. There are several species of lizard (such as the komodo dragon) that could qualify as k-strategists within their environment.
