Summary of "Caddisfly Assemblages in Metal Contaminated Rivers of the Tikhaya Basin, East Kazakhstan."

The Ulba river basin is one of the most industrialized regions of Kazakhstan. The development of mining and metallurgical industries has increased pollution of the basin's surface waters by heavy metals, primarily zinc and copper. The taxonomical structure of Trichoptera was studied in reference and impacted reaches of the river basin. A significant decrease in Trichoptera species richness was recorded in the most polluted areas. A total of 35 species were identified at the reference site of the Breksa River, but only 14 in the impacted sites. Ceratopsyche newae, Dicosmoecus palatus, Glossosoma altaicum and Rhyacophila sibirica showed a significant reduction at sites with high heavy metal concentrations.

Medical and Biotech [MESH] Definitions

The genomic analysis of assemblages of organisms.

Neutral or negatively charged ligands bonded to metal cations or neutral atoms. The number of ligand atoms to which the metal center is directly bonded is the metal cation's coordination number, and this number is always greater than the regular valence or oxidation number of the metal. A coordination complex can be negative, neutral, or positively charged.

Proteases which use a metal, normally ZINC, in the catalytic mechanism. This group of enzymes is inactivated by metal CHELATORS.

The technique of washing tissue specimens with a concentrated solution of a heavy metal salt and letting it dry. The specimen will be covered with a very thin layer of the metal salt, being excluded in areas where an adsorbed macromolecule is present. The macromolecules allow electrons from the beam of an electron microscope to pass much more readily than the heavy metal; thus, a reversed or negative image of the molecule is created.

A family of soluble metal binding proteins that are involved in the intracellular transport of specific metal ions and their transfer to the appropriate metalloprotein precursor.
