Under the surface of most streams a strange world exists, made up hundreds small critters called aquatic invertebrates. “Aquatic” means they live in water and “invertebrate” have no backbones or even skeletons. Some body parts that look like came from an alien planet. slippery bodies adapted to rushing stream water. These organisms play many important roles. for 7 years others as little 2 weeks...

The current decline of invertebrates worldwide is alarming. Several potential causes have been proposed but metal pollutants, while being widespread in the air, soils and water, so far largely overlooked. Here, we reviewed results 527 observations effects arsenic, cadmium, lead mercury on terrestrial invertebrates. These four well-studied metals are considered as priorities for public health wh...

This study examined whether the diversity and relative abundance of ground-dwelling invertebrates changed in relation to type of vegetation cover. Invertebrate taxon diversity and relative abundance were assessed with pitfall traps placed under the native shrubs Olearia bullata and Coprosma propinqua, and in surrounding patches of exotic pasture. A total of 1935 invertebrates and at least 152 i...

Why don’t we see more invertebrates playing? Play may have arisen in vertebrate lineages as a by-product of traits associated with the complex behaviours and cognitive abilities, in turn associated with increased brain size. Although we know that invertebrates are far from the mindless machines they were once considered to be, it might be that the neural architecture available to add new levels...

The diversity and habitat requirements of invertebrates associated with dead wood have been the subjects of hundreds of studies in recent years but we still know very little about the ecological or economic importance of these organisms. The purpose of this review is to examine whether, how and to what extent invertebrates affect wood decomposition in terrestrial ecosystems. Three broad conclus...

Marine invertebrates, such as oysters, mussels, clams, scallop, jellyfishes, squids, prawns, sea cucumbers and sea squirts, are consumed as foods. These edible marine invertebrates are sources of potent bioactive peptides. The last two decades have seen a surge of interest in the discovery of antioxidant peptides from edible marine invertebrates. Enzymatic hydrolysis is an efficient strategy co...

The food habits of Trachinotus paitensis, in San Ignacio Lagoon B.C.S., Mexico, were investigated. We observed that T. paitensis is carnivorous, feeding mainly on benthic invertebrates (the gastropods Anachis spp., Bittium spp., and the crustacean larvae). We concluded that T. paitensis is an opportunist predator that impacts mainly on epibenthic invertebrates.

The study is focused on the bio monitoring of Kukatpally IDL Lake using Benthic Macro invertebrates. It is a special way of assessing the water quality using Macro invertebrates (Bio-monitoring Working Party) as indicators of pollution. The results have been expressed as Bio-Mapping which denotes visually the level of pollution at different points.
