Conservation landmarks: bureau of biological survey and national biological service Conservation landmarks: bureau of biological survey and national biological service

A century separates the recent development of the National Biological Service (NBS) and an early predecessor, the Bureau of Biological Survey (BBS). Both organizations were established at critical crossroads for the conservation of the nation's living biological resources and are conservation landmarks of their times. The BBS of the 192()'s was described as 'a government Bureau of the...

Probable epizootic chlamydiosis in wild California (Larus californicus) and ring-billed (Larus delawarensis) gulls in North Dakota Probable epizootic chlamydiosis in wild California (Larus californicus) and ring-billed (Larus delawarensis) gulls in North Dakota

During the summer of 1986, more than 400 California gulls (Larus californicus) and ring-billed gulls (Larvus delawarensis), primarily fledglings, died on an island in Lake Sakakawea near New Town, North Dakota (USA). Mortality was attributed largely to chlamydiosis. Necropsy findings in nine carcasses included splenomegaly (n = 9), hepatomegaly (n = 4), and pericarditis (n = 1). Livers...

Waterfowl diseases: Causes, prevention, and control Waterfowl diseases: Causes, prevention, and control

Preventing and controlling disease in waterfowl is a difficult job. Few tools are available to deal with disease in highly mobile, unconfined animal populations, and few managers are trained and experienced in the prevention and control of avian diseases. Furthermore, the geographic distribution, frequency of occurrence, magnitude of losses, and causes of diseases in waterfowl, as in...

First record of an hypopus (Acari: Hypoderatidae) from a jaeger (Aves: Charadriiformes: Stercorariidae) First record of an hypopus (Acari: Hypoderatidae) from a jaeger (Aves: Charadriiformes: Stercorariidae)

Thalassornectes (Alcidectes) aukletae, originally described from two species of auklets (Charadriiformes: Alcidae) from maritime eastern Russia, is reported from a third species of pelagic charadriiform (Stercorariidae), the pomarine jaeger, Stercorarius poinarinus (Temminck), from Florida. The specimens from the jaeger are slightly smaller, the genital apodeme is more heavily...

Abnormal chemical element concentrations in lichens of Isle Royale National Park Abnormal chemical element concentrations in lichens of Isle Royale National Park

Lichens have been used for many years to monitor changes in deposited airborne chemical elements in many areas, but few studies have focused on areas suspected of experiencing slightly elevated pollution. Detection of subtle patterns of slightly elevated pollutants calls for developing several lines of evidence as opposed to single line studies used in heavily polluted areas. This study...
