Migration of Aquatic Invertebrates
2004Aquatic invertebrates are dependent on dispersion and migration for sustainable populations. Especially in running waters, these processes play a dominant role. Ephemeral water bodies have probably triggered dispersion phenomena in the evolutionary past.

The involvement of metallothionein in the development of aquatic invertebrate
Aquatic Toxicology, 2012The many documents on metallothioneins (MTs) in aquatic organisms focus especially on their use as biomarkers in environmental monitoring programs, but there are a few papers that summarize the physiological role of MTs in aquatic organisms especially in their development.

Infertility in male aquatic invertebrates: A review
Aquatic Toxicology, 2012As a result of endocrine disruptor studies, there are numerous examples of male related reproductive abnormalities observed in vertebrates. Contrastingly, within the invertebrates there have been considerably less examples both from laboratory and field investigations.

Uptake and depuration of pharmaceuticals in aquatic invertebrates
Environmental Pollution, 2012The uptake and depuration of a range of pharmaceuticals in the freshwater shrimp (Gammarus pulex) and the water boatman (Notonecta glauca) was studied. For one compound, studies were also done using the freshwater snail Planobarius corneus. In G. pulex, bioconcentration factors (BCFs) ranged from 4.6 to 185,900 and increased in the order moclobemide ...

Ecotoxicology, aquatic invertebrates
Global chemical pollution is recognized as a major threat to marine and freshwater environments. The huge biodiversity of aquatic invertebrates, their key position in ecosystem functioning, their suitability for field and laboratory experimental approaches, the existing knowledge on their ecology, along with growing genomic resources made invertebratesChaumot, Arnaud +3 more

Pesticide Residues in Fish and Aquatic Invertebrates
1983Over the past 6 years a great number of fish and aquatic invertebrates from experimental and commercial fishponds have been analyzed for the presence of organochlorine insecticides and polychlorinated biphenyls (PCBs). Invariably, all specimens contained DDE and PCBs and in many instances also DDT, DDD and BHC isomers.

As pointed out by the editors of several recent books (Barnes and Minshall 1983, Resh and Rosenberg 1984; Merritt and Cummins 1984), the freshwater biology literature, especially that concerned with stream ecology and aquatic invertebrates, has expanded enormously in the last 15 years. Research at Coweeta follows this worldwide trend.

Sponges are classified as the simplest metazoan phylum of the animal kingdom. They have a hollow circular body that filters out the water of the environment, retaining the food. Spongin is a protein that is the main part of the body and a “skeleton” of spikes consisting of calcium carbonate and silica hardens it.
