A comparative study of the chromosomes from five species of the genus Rana

Creator:: Haertel, John David
Abstract:: The karyotypes of five species of ranid frogs were determined from metaphase plates of bone marrow cells. The colchicine, hypotonic- citrate, blaze-dry technique was used to obtain the plates. Morphometric datawere obtained from the karyotypes and compared with other species of the genus Rana. Like most other members of the...

Morphological variations in populations of Lacerta from islands in the Adriatic Sea

Creator:: Clover, Robert C.
Abstract:: Phenetic relationships in insular populations of Lacerta sicula and L. melisellensis correspond to geologic ages of the islands in two regions of the Adriatic Sea. Populations of L. melisellensis on older islands are more similar to populations of L. sicula than are L. melisellensis from younger islands, and examination of...
