Crustaceans are major constituents to aquatic ecosystems that provide a variety of
ecological and economic services. Individual crustacean species are adept at occupying …

Endocrine disrupting chemicals (EDCs) are found in every environmental medium and are
chemically diverse. Their presence in water resources can negatively impact the health of …

We describe the draft genome of the microcrustacean Daphnia pulex, which is only 200
megabases and contains at least 30,907 genes. The high gene count is a consequence of …

Research into the lives of animals in their natural environments has revealed a rich tapestry
of complex social relationships and previously unsuspected social and mating systems. The …

Sex-determining mechanisms are diverse among animal lineages and can be broadly
divided into two major categories: genetic and environmental. In contrast to genetic sex …

Vitellogenesis in crustaceans is an energy-consuming process. Though the underlying
mechanisms of ovarian maturation in decapod Crustacea are still unclear, evidence …

The water flea Daphnia magna reproduces primarily by cyclic parthenogenesis.
Environmental stimuli that signal a change to adverse conditions induce the organisms to …

Methyl farnesoate (MF) is a unepoxidated form of insect juvenile hormone (JH) III that is
secreted by the mandibular organ (MO) in several crustaceans. MF was first isolated from …

The issue of endocrine disruption (ED) in invertebrates has generated remarkably little
interest in the past compared to research with aquatic vertebrates in this area. However, with …

Juvenile hormone is an essential regulator of major developmental and life history events in
arthropods. Most of the insects use juvenile hormone III as the innate juvenile hormone …
