R represents the population growth rate. K represents the carrying capacity, which is the number of individuals of a species that the resources in a habitat can support. The term selected refers to r-selection r -selected species are those that emphasize high growth rates, typically exploit less-crowded ecological niches, and produce many offspring, each of which has a relatively low probability of surviving to adulthood (i.e., high r, low K). A typical r species is the dandelion (genus Taraxacum). R-selected species exhibits comparability. R-selected species can be compared to the things which differ from it.

R-Selected Species in Temperate Deciduous Forest Characteristics: density-independent: many offspring for better chance of survival, low energy investment in offspring, small young Examples: White Tailed Squirrel, Eastern Chipmunk, Carpenter Bees (Xylocopa) Those organisms described as r-strategists typically live in unstable, unpredictable environments.

Completing Linnaeus's inventory of the Swedish insect fauna

Slide 12 of 52 The r selected species live in populations that are highly variable. The fittest individuals in these environments have many offspring and reproduce early. Examples: Oysters, Insects- Mosquitos, Daphnia, Goldenrod K selected species live in populations that are at or near equilibrium conditions for long periods of time. Competitive for limited Start studying R and K Selected Species. Learn vocabulary, terms, and more with flashcards, games, and other study tools. ERT-3.B.2: r-selected species tend to be small, have many offspring, expend or invest minimal energy for each offspring, mature early, have short life spans, and may reproduce only once in their lifetime. Competition for resources in r-selected species' habitats is typically relatively low.
