Three pleurobranch species; Berthellina citrina (Ruppel and Leuckart, 1828), Pleurobranchus grandis (Pease, 1868) and Pleurobranchus albiguttatus (Bergh, 1905) were collected from seven sites in the upper intertidal zone, on the North Western Coast of the Red Sea; Egypt. They inhabit the lower surfaces of medium sized stones in pools containing wat...

Abstract: The unionid freshwater mussel Nitia teretiuscula (Philippi, 1847) was collected from the River Nile at Sohag Governorate. Both the spatial and temporal distributions were investigated using a systematic sampling technique. In addition, the inter-relationships between the abundance of the studied species and some measured environmental fac...

This study gives highlights on the biodiversity of spiders in an olive trees orchard, a lemon trees orchard, and webs of Cyrtophora citricola at Jazirat Shandweel District, Sohag Governorate, Egypt. In addition, it gives a preliminary list of spiders based on the main taxonomic characters. The sampling was carried out weekly or monthly during the p...

Abstract: Spiders have an important role in the agroecosystems. They are effective in suppressing the pest populations as biological controllers. This study aimed to study the abundance, temporal distribution and diversity of spiders in an agriculture research site at Jazirat Shandweel, Sohag District, Sohag Governorate, Egypt. The sampling was car...

The present study dealt with the description of the reproductive and gametogenic cycles and the embryonic development of the freshwater mussel Nitia teretiuscula from the River Nile. Macro and micro-anatomy showed that the present species is dioceous and gonadosomatic indices showed that the species is semiannual and had two gonadal growth periods,...

Berthellina citrina (Rüppell and Leuckart, 1828) is a common Pleurobranchid gastropod in the intertidal area of the Red Sea. It has distinct color pattern variation from pale yellow, orange to red. The present study aimed to evaluate whether the variation of these color patterns are due to polymorphism, or may be speciation. Anatomically, the three...

The present work aims to study the spatial and temporal variation in the distribution and abundance of Leptochelia erythraea that were collected seasonally during the period July 2006 to April 2008 and the relationships between their abundance and the environmental variables in an intertidal flat on the NorthWestern Coast of the Red Sea, Egypt.
