R- And K-Selection And Microbial Ecology



Abstract. The essence of the concept of r – and K-selection is that organisms strive to maximize their fitness for survival in either uncrowded ( r -selection) or crowded (K-selection) environments.Fitness is defined following ecological convention as the proportion of genes left in the population gene pool (Pianka, 1983, p. 10).

7/1/2009  · Abstract. Increased root exudation under elevated atmospheric CO 2 and the contrasting environments in soil macro- and microaggregates could affect microbial growth strategies. We investigated the effect of elevated CO 2 on the contribution of fast- ( r -strategists) and slow-growing ( K-strategists) microorganisms in soil macro- and microaggregates.We fractionated the bulk soil from the …

The terms r -selection and K-selection have also been used by ecologists to describe the growth and reproductive strategies of various organisms. Permissions … City of Microbes, Watnick and Kolter have referred to the biofilms as “ microbial cities” and the planktonic cells as pioneers or explorers whose primary function is the …

high competitive ability. These populations are also called r -strategists and K-strategists, respectively. Andrews and Harris (5) provided a framework to apply the concept of r – and K-selection to microbial ecology . Due to the problem of identi-fying populations in natural bacterial communities, life strate-, The contribution by T. Fenchel discusses the ecology of heterotrophic microflagellates. J. H. Andrews and R . F. Harris present the concept of r – and K-selection and its relevance to microbial ecology .
