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...

Pollution associated with marine debris is of global ecological concern, as it threatens wildlife and local economies. Submerged alters benthic species composition community characteristics. The study site Jaguri, Jeju Island, where a variety submerged was found, used to investigate the impact on macrobenthic fauna sandy rocky substrates. dominant macrobenthos taxon differed by sediment type; p...

In shallow lakes, floating-leaved plants can produce dense lakebeds that dramatically alter freshwater ecosystems and impact macrobenthic communities. Shorebirds are morphologically diverse utilize different foraging strategies; they partition food resources to achieve coexistence due differences in availability. this study, we defined shorebird guilds using a principal component analysis expla...

A general study with the objective to classify ecotoxicity status of macrobenthose associated with dominant toxic zoanthids in Hormuz Island is presented. Hence, a novel model based on hard bottom macrobenthos and the related substrate composition was suggested to be used for testing the accumulated palytoxin (PTX) in macrobenthose exposed to Zoanthus sansibaricus. Direct and rapid assessment i...

The growing development of offshore wind energy installations across the North Sea is producing new hard anthropogenic structures in the natural soft sediments, causing changes to the surrounding macrobenthos. The extent of modification in permeable sediments around a gravity based wind turbine in the Belgian part of the North Sea was investigated in the period 2011-2012, along four gradients (...

Biological diversity examines to study the habitats of the earth and marine environment which has a greater extent covers the oceans and soft sediment habitats. It helps us to find the associated terrestrial systems, and knowledge of marine biodiversity. Habitats are holding an assorted arrangement of macrobenthic communities which plays important roles in ecosystem processes like reprocess the...
