This article reviews the production of different phenotypes from the same genotype in the
same environment by stochastic cellular events, nonlinear mechanisms during patterning …

Discussions that are aimed at understanding the maintenance of sexual reproduction are in
a bit of a quagmire owing to the many competing theories that have been proposed. Also …

The consequences of variable rates of clonal reproduction on the population genetics of
neutral markers are explored in diploid organisms within a subdivided population (island …

Numerous theories have been proposed to explain the advantages of sexual recombination—
the exchange of hereditary material between different genomes or homologous …

Ancient asexuals–organisms that have lived without sex for millions of years–offer unique
opportunities for discriminating among the various theories of the maintenance of sex. The …

Recently, we briefly reported on the first case of parthenogenesis in the decapod Crustacea
which was found in the Marmorkrebs or marbled crayfish, a cambarid species of unknown …

Adaptation of reef corals to climate change is an issue of much debate, and often viewed as
too slow a process to be of relevance over decadal time scales. This notion is based on the …

Despite the enormous theoretical attention given to the evolutionary consequences of
sexual reproduction, the validity of the key assumptions on which the theory depends rarely …

Neutral models characterize evolutionary or ecological patterns expected in the absence of
specific causal processes, such as natural selection or ecological interactions. In this study …

There is a close association between parthenogenesis and polyploidy. For this reason, we
undertook a karyological analysis to test whether the parthenogenetic Marmorkrebs …
