The Amphibians and Reptiles of Costa Rica
World-renowned for its biological diversity and model conservation system, Costa Rica is home to a wide variety of amphibians and reptiles, from the golden toad to the scorpion lizard to the black-headed bushmaster. Jay M. Savage has studied these fascinating creatures for more than forty years, and in The Amphibians and Reptiles of Costa Rica he provides the most comprehensive, up-to-date treatment of their biology and evolution ever produced. Costa Rica has played, and continues to play, a pivotal role in the study of tropical biology as well as the development of ecotourism and ecoprospecting, in part because more than half of the amphibians and reptiles in Costa Rica are also found elsew...
Studies on Selected Myxobacteria Pathogenic for Fishes and on Bacterial Gill Disease in Hatchery-reared Salmonids
Morphological, physiological, and serological studies on 55 myxobacteria isolated principally from gill disease, tail rot, and other myxobacterial infections showed that a variety of myxobacteria occur in these infections. Athought there were different morphological types of myxobacteria, all strains from freshwater and estuarine sources were physiologically similar. Isolates from marine sources were physiologically less active than the other test organisms.

Efficacy, Toxicity, and Residues of Nifurpirinol in Salmonids
Nifurpirinol (NFP), also know by code name P-7138, was tested for control of furunculosis, myxobacterioses, and vibriosis, and for effects on rainbow trout, coho, and chinook salmon under various conditions. Further tests are needed to verify the use of NFP for control of other bacterial diseases.
Studies of Estuarine Dependence of Atlantic Coastal Fishes
In 1965 the Sandy Hook Marine Laboratory began research on the extent to which migratory fishes of the Atlantic coast depend on estuaries during the early period of their lives.
