Characteristics of qualitative and quantitative composition benthos organisms on littoral spring spawning grounds Kurile Lake was given for the first time in 1974. Grounds typically consist intermiting plots pebble or gravel (clean covered by biocrust) with permanent sand component, sometime silty. The silt component rivers Srednaya Kirushutk is more impressive comparing to lake grounds. Chiron...

ated with transitions to benthic communities dominated by noncalcareous benthos (4, 8). The results of Kayanne et al. (1) reveal metabolic measures to be sensitive indicators of reef health (9), but the findings more likely reflect the condition of the local sampling site than the normal behavior of healthy reef communities.

The purpose of this study was to document existing benthic organisms of the lower West River in New Haven and West Haven, Connecticut, in order to enable monitoring of salt marsh restoration. Seventeen sites were sampled between the Chapel Street Bridge and the mouth of the West River during the month of July 1995. All sites contained polychaete worms and other organisms typical of estuarine sy...

Organisms living in or on the sediment layer of water bodies constitute the benthos fauna, which is known to harbour a large number of species of diverse taxonomic groups. The benthos plays a significant role in the nutrient cycle and it is, therefore, of high ecological relevance. Here, we have explored a DNA-taxonomic approach to access the meiobenthic organismic diversity, by focusing on obt...

Key to understand predator choice is the relationship between predator and prey abundance. There are few studies related to prey selection and availability. Such an approach is still current, because the ability to predict aspects of the diet in response to changes in prey availability is one of the major problems of trophic ecology. The general objective of this study was to evaluate prey sele...

macrobentos frequency and biomass was investigated in the gorgan bay in 2011. five sampling sites were chosen to collect benthos and sediment from the bay using a van veen grab sampler. samples were collected seasonally. macrobenthos were indentified and their biomass was recorded. sediment heavy metals concentration were measured using atomic absorption spectroscopy. a total of 11 families bel...

Persistent organic pollutants (POPs) have been at the forefront of environmental contamination research even before their ban in 2001 Stockholm Convention. Their relation to different compartments environment (biotic and abiotic) has thoroughly investigated. This article aims identify whether benthos could represent a reliable indicator with POPs highlight its potential transfer role between ab...

Water is a source of life that plays an important role for all living things. Rivers are one the water sources vulnerable to pollution. This study aimed evaluate quality Way Napal river based on diversity plankton and benthos. The research was conducted from November 2020 March 2021. Sampling analysis were performed by field technicians SEAMEO BIOTROP Environmental Laboratory. Plankton calculat...
