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.
Is an iguana r selected Or k selected?
k selected
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
Are whales r selected organisms?
no
Is a sperm whale r-selected or k-selected species?
K-selected
What is the difference between r selected and K selected species populations?
r-selected species have a high reproductive rate, producing many offspring with little parental care in unstable or unpredictable environments. K-selected species have a low reproductive rate, producing few offspring with high parental care in stable environments. r-selected species often have a quick maturation and short lifespan, while K-selected species have a slower maturation and longer lifespan.
Are grasshopper r-selected organism?
Grasshoppers are R-selected organisms. R-selected organisms are said to have a high ability to reproduce. They should also have a small body size, early maturity, a short generation time, and a wide offspring dispersion.
What is the difference between r-species and k-species?
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 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.
What are the differences between the K-selected and r-selected reproductive strategies in terms of their impact on population growth and survival?
K-selected and r-selected reproductive strategies differ in their impact on population growth and survival. K-selected species have fewer offspring but invest more resources in each individual, leading to slower population growth but higher survival rates. In contrast, r-selected species produce many offspring with minimal parental care, resulting in rapid population growth but lower individual survival rates.
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)?
