Implantation of Subcutaneous Radio Transmitters in the Harbor Seal (Phoca vitulina)

Radio telemetry has become a standard tool for studying the behavior, physiology, life history traits, and population dynamics of marine mammals. Radio transmitters typically are attached to the hind flippers of pinnipeds or glued to the fur using marine epoxy or other cyanocrylare adhesives (Fedak et al. 1983, Bengtson 1993, Jeffries et al. 1993). Longterm data acquisition is difficult, however, because radio-flipper transmitters commonly tear from the webbing of the flipper and instruments that are glued to the fur are shed during the seasonal molt.

Politics and Trade in the Former Soviet Union

Fifteen independent countries emerged from the collapse of the Soviet Union in 1989-91. Aside from the Russian Federation, the former Soviet Republics lie in four geographic regions: the Caucasus (Armenia, Azerbaijan, Georgia); Central Asia (Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan, and Uzbekistan); the Baltics (Estonia, Latvia, Lithuania); and Eastern Europe (Belarus, Moldova, Ukraine).
