K-selected species? Explore survivorship curves, showing how certain species differ The opposite of an r-selected species is known as a K-selected species. K- strategy organisms produce very few young, but they protect and nurture them so that a Apr 24, 2014 Disturbance is a key factor shaping species abundance and diversity in plant communities. Here, we use a mechanistic model of vegetation tions of the r- and K-selection theory is that competition for food is more intense for K- avoids the issue of whether r-selected species are regu- lated by When something like climate change causes heavier selection on species, is it possible for some species that have r-selected characteristics to … Feb 18, 2018 R-selected species are those that favor a large number of offspring. This includes animals like insects, amphibians, many fish, and reptiles.

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.

Completing Linnaeus's inventory of the Swedish insect fauna
There are also animals that have the R-selected characteristics. A good way of thinking about K selected species is to think of a mature forest tree. It exists in non disturbed native forest habitats. Forest trees grow slowly and reach reproductive age late, having to devote much energy to growth and maintenance.

However they have a Type 3 survival curve which means that most of the offspring die off during their early ages and the few live to their old age. K-selected species possess relatively stable populations fluctuating near the carrying capacity of the environment.
