benthic organisms have been studied in past to assess the health of an aquatic ecosystem. moreover, being sedentary forms they have been used as indicator organisms. in the present study, an attempt has been made to study the distribution and assemblage of major macrobenthic forms occurring in ponnani estuary. a total of 23 genera of benthic invertebrate fauna belonging to 6 groups viz., polych...

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...
