Water fleas of the genus Daphnia have been a model system for hundreds of years and is
among the best studied ecological model organisms to date. Daphnia are planktonic …

Daphnia offer a variety of benefits for the study of epigenetics. Daphnia's parthenogenetic
life cycle allows the study of epigenetic effects in the absence of confounding genetic …

The question of why organisms reproduce sexually is still a matter of controversy. In this
account, Professor Maynard Smith considers the selective forces responsible for the origin …

Allozyme studies of Daphnia pulex populations in southern Ontario revealed marked Hardy–
Weinberg deviations, complete gametic phase imbalance, and high heterozygosity values …

1. The conditions required to initiate development of resting eggs of thirty‐six clones of
Daphnia representing seven species were investigated. 2. The temperature of both dark …

Ploidy-level variation among asexual clones of Daphnia pulex showed a clear latitudinal
pattern. Only a single diploid clone was identified at the high-arctic Igloolik site, and it …

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 …

In this review we consider sexual dimorphism in copepods, cladocerans, and rotifers. All
three groups may be common components of freshwater and sometimes estuarine …

By allowing mutations to accumulate spontaneously in different lines derived from a single
female of an obligately parthenogenetic Daphnia, it has become possible to estimate the …

Most daphnid species adopt parthenogenesis and sexual reproduction differentially in
response to varied environmental cues, resulting in the production of diploid progenies in …
