Brucellosis in Marine Mammals
Last Updated: July 28, 2009 Importance Brucella infections have recently been recognized in seals, sea lions, walruses, dolphins, porpoises, whales and an otter. This organism appears to be widespread in marine mammals, and has probably been endemic in these populations for a long time. The clinical significance is uncertain. A few infections have been associated with placentitis/abortions, neo...

متن کاملPutting Energy Back in Control
Energy is one of the fundamental concepts in science and engineering practice, where it is common to view dynamical systems as energy-transformation devices. This perspective is particularly useful in studying complex nonlinear systems by decomposing them into simpler subsystems that, upon interconnection, add up their energies to determine the full system’s behavior. The action of a controller...
متن کاملOsmoregulation in marine mammals.
Osmoregulation in marine mammals has been investigated for over a century; however, a review of recent advances in our understanding of water and electrolyte balance and of renal function in marine mammals is warranted. The following topics are discussed: (i) kidney structure and urine concentrating ability, (ii) sources of water, (iii) the effects of feeding, fasting and diving, (iv) the renal...
متن کاملCommunication in Marine Mammals
Communication is a process by which a sender produces a signal, which alters the probability of a subsequent behav ior in a receiver(s). Often, but not always, communication facilitates social behavior. Given the highly social behavior found in many marine mammals, the study of communicative behavior is essential to understanding the role that signaling plays in regulating social interactions ...
