Effect of Environmental Variations on Macro-benthos Occurrence and Abundance of the Red Sea Coast of Egypt

Abstract

Benthic communities vary according to changes in the environmental factors in addition to human impacts. The present study aimed to investigate the changes of macro-benthos community in three sites at the Red Sea Coast of Egypt during summer (2019) and winter (2020). Benthic communities were studied at five sampling groups (Hs: El-Hamrawen summer, Ms: Sedy Malek summer, Hw: El-Hamrawen winter, Mw: Sedy Malek winter, Pw: Porto Ghalb winter). The results indicated that dissolved oxygen is the most Extensive plasticity of a Sea over a strong latitudinal temperature gradient limited acclimatization potential
