<div><p><em>The estuaine environment are dynamic and they are  the intermediate zone between the marine and fresh water regions.  This makes the estuarine  region  more dynamic  in physical and chemical characteristic. These regions serves as a passage for  the continental  materials reach the marine environment.  Because of the influence of fresh water and marine water this regions the depositional systems are dynamic and complex in nature. Despite the complexity of the of the environment, the textural analsysis and interpretation of the same provides insight into the prevailing deposition environment.  The present study are carried out in the Uppar Estuary which joins with Bay of Bengal on the east coast of India. The Sedimentological analysis indicates that sediments  most of the locations the sediments are very poorly to well sorted  with mean size ranging from 1.03 to 5.97φ. The skewness value  ranged from  -0.09 to 0.48. The kurtosis varies form 0.94 to 1.54 The seasonal variations  within the station are conspicuous. This indicates the sediment distribution pattern in controlled by the  marine  as well monsoon rainfall  in this region.</em></p></div>

1. Two batches of diamondback terrapins have been kept for a whole year, one in sea water the other in tap water, and seasonal variations have been recorded in the composition and osmotic pressure of the blood plasma. 2. All year round the sea-water animals have a higher osmotic pressure and higher concentrations of Na, K, Cl and urea than fresh-water animals. It is in July, however, that these differences are the least marked. 3. The seasonal variations recorded are linked in particular to the conditions of osmotic stress imposed by the environment. 4. The results are discussed within the framework of hibernation and of the evolution among chelonians from fresh water to sea water.

Polyacrylamide gel electrophoretic (PAGE) technique was used to examine the esterase pattern of Ctenidia, Hepatopancreas, Hemolymph, Intestine, Mantle. Foot of the Lamellidens corrianus. The zymograms revealed the varied pattern of esterase both in number and type. This varied pattern suggested several roles for these enzymes present in different tissues.

Course Of Study

The present study was carried out to assess the planktonic diversity and seasonal variations in the physic-chemical characteristics of Pohra, Wadali and Chhatri surface water reservoirs around Amravati during June 2014 to May 2015. During the course of study the zooplankton in the reservoir under investigation is represented by five major groups i.e. Ostracoda, Rotifera, Cladocera, Protozoa and Copepoda.  Among phytoplankton a total of 28 algal species were recorded from all the reservoirs under study with 14 taxa from Chlorophyceae, 9 taxa from Bacillariophyceae and 8 from Cyanophyceae. The Chhatri reservoir was found to contain most of the pollution indicator species. Wadali reservoir also exhibited few pollution tolerant species. The water in all the reservoirs was found to be eutrophic in the order of Pohra > Wadali > Chhatri.
