Intersexuality in aquatic invertebrates: Prevalence and causes

Science of the Total Environment, 2017
This review is the first assembling information on intersexuality in aquatic invertebrates, from freshwater to estuarine and marine environments. Intersex is a condition whereby an individual of a gonochorist (separate sexes) species has oocytes or distinct stages of spermatogonia, at varying degrees of development, within the normal gonad of the ...

A review of environmental epigenetics in aquatic invertebrates

Marine Pollution Bulletin
Aquatic ecosystems face significant challenges due to increasing human-induced environmental stressors. Recent studies emphasize the role of epigenetic mechanisms in the stress responses and adaptations of organisms to those stressors. Epigenetics influences gene expression, enabling phenotypic plasticity and transgenerational effects.

Steroids in aquatic invertebrates

Ecotoxicology, 2007
Steroid molecules are present in all invertebrates, and some of them have established hormonal roles: this is the case for ecdysteroids in arthropods and, to a lesser extent, for vertebrate-type steroids in molluscs. Steroids are not only hormones, they may also fulfill many other functions in chemical communication, chemical defense or even digestive ...

The tolerance of oxygen by aquatic invertebrates

Proceedings of the Royal Society of London. Series B - Biological Sciences, 1955
Abstract Aquatic invertebrates were found to be affected to very different extents by water saturated with oxygen; some species were quickly killed, others were slowly injured, while yet others showed no ill effects in the course of weeks.

Aquatic Invertebrates

1997
The aquatic invertebrates of Amazonian floodplains can be divided into three large communities: the zooplankton, the benthos and the perizoon. Most studies deal with zooplankton, concentrating on taxonomic aspects and on community structure during the hydrological cycle.

Chemoreception in Aquatic Invertebrates

2020
This chapter focuses on chemoreception in aquatic invertebrates, animals that, by the nature of their habitat, sense molecules in solution, as is typical of vertebrate taste. Many aquatic invertebrates have a well-developed chemical sense that enables the animals to monitor changes in the chemical composition of the aqueous environment in which they ...
