Soil bacteria produce a diverse array of antibiotics, yet our understanding of the specific roles of antibiotics in the ecological and evolutionary dynamics of microbial interactions in natural ...

The process of speciation allows a single species to diverge into two. Dive into the different versions of this process, including “allopatric speciation” and “sympatric speciation,” and discover how ...

Two semiarboreal skinks (Mabuya) are narrowly sympatric in the Kalahari desert, whereas two terrestrial species are broadly sympatric both with one another and with the semiarboreal species. We ...

Three models for sympatric and alleged sympatric speciation are known in evolutionary research. The first model, the most "pure form" of sympatric speciation, describes the development of two species ...

This is a preview. Log in through your library . Abstract A literature survey reveals many problems with the use of 1.3 as an ecological constant. To date, much of the empirical support for the ...

The Midas cichlid fish from the crater lakes of Nicaragua are one of the the best known examples for sympatric speciation. They evolved from a source population into a variety of independent species ...
