R-selected organisms, those emphasizing a fast growth rate, high number of offspring, include rabbits, bacteria, salmon, plants such as weeds and grasses, etc. The strategy for R-selected organisms includes producing a lot of offspring, producing them often, and having a relatively short lifespan. R-selected species usually don't care for offspring, whereas k-selected species such as

Many r-selected species tend to be opportunists, meaning that they reproduce and disperse rapidly when conditions are favorable or when a disturbance opens up a new habitat or niche for invasion. This could occur in the early stages of ecological succession. Once their There's another possibility, although it's hard to tell without a reprex: filter and select could be masked by another package.Whenever I have errors I can't work out with those two, I check my packages immediately Items ordered from K-Selected US may be subject to tax in certain states, based on the state to which the order is shipped. If an item is subject to sales tax, in accordance with state tax laws, the tax is generally calculated on the total selling price of each individual item, including shipping and handling charges, gift-wrap charges and other service charges, less any applicable discounts. r/K selection theory describes the combination of traits in a living organism that alternatingly emphasizes quality and quantity of offspring.

R selected vs k selected

r-selected species? K-selected species generally produce fewer offspring. K-selected species generally show traits that improve ability to compete for resources. K-selected species generally show greater parental care. K- and r- selected species: (A) Elephants are considered K-selected species as they live long, mature late, and provide long-term parental care to few offspring.
