The research has been conducted in 3 biggest cemeteries of Chisinau city: Central (“Armenian”), “Saint Lazarus” (“Doina”) and Jewish. We found 9 species of small mammals (7 species of rodents and 2 shrews). Species of rodents were Clethrionomys glareolus, Microtus rossiaemeridionalis, Apodemus flavicollis, A. sylvaticus, A. uralensis, Rattus norvegicus and Mus musculus and 2 shrew species – Sorex araneus and Crocidura suaveolens. A.sylvaticus was dominant species, followed by M. rossiaemeridionalis and A. flavicollis.

Fingernail Clams

Fingernail clams (Muscu1ium transversum) are dominant bottom-dwelling animals in some waters of the midwest U.S. These organisms are key links in food chains leading from nutrients in water and mud to fish and ducks which are utilized by man. In the mid-1950’s, fingernail clams disappeared from a 100-mile section of the Illinois R., a tributary of the Mississippi R. Some factor(s) in the river and/or sediment currently prevent clams from recolonizing areas where they were formerly abundant. Recently, clams developed shell deformities and died without reproducing. The greatest mortality and highest incidence of shell deformities appeared in test chambers containing the highest proportion of river water to well water. The molluscan shell consists of CaCO3, and the tissue concerned in its secretion is the mantle. The source of the carbonate is probably from metabolic CO2 and the maintenance of ionized Ca concentration in the mantle is controlled by carbonic anhydrase. The Ca is stored in extracellular concentric spherical granules(0.6-5.5μm) which represent a large amount of inertCa in the mantle. The purpose of this investigation was to examine the role of raw river water and well water on shell formation in the fingernail clam.
