Bacteremia in free-ranging Hawaiian green turtles, Chelonia mydas, with fibropapillomatosis Bacteremia in free-ranging Hawaiian green turtles, Chelonia mydas, with fibropapillomatosis

Past studies of free-ranging green turtles Chelonia mydas with fibropapillomatosis (FP) in Hawaii have shown that animals become immunosuppressed with increasing severity of this disease. Additionally, preliminary clinical examination of moribund turtles with FP revealed that some animals were also bacteraemic. We tested the hypothesis that bacteraemia in sea turtles is associated with...

Sporulation and survival of Toxoplasma gondii oocysts in seawater Sporulation and survival of Toxoplasma gondii oocysts in seawater

We have been collaborating since 1992 in studies on southern sea otters (Enhdyra lutris nereis) as part of a program to define factors, which may be responsible for limiting the growth of the southern sea otter population. We previously demonstrated Toxoplasma gondii in sea otiers. We postulated that cat feces containing oocysts could be entering the marine environment through storm run...

Elemental chemistry of four lichen species from the Apostle Islands, Wisconsin, 1987, 1995 and 2001 Elemental chemistry of four lichen species from the Apostle Islands, Wisconsin, 1987, 1995 and 2001

Four lichen species sampled three times over a 15-year time span at four of the Apostle Islands, Wisconsin were analyzed for 16 chemical elements in order to determine time trends and spatial patterns. Factor analyses of the data revealed that elements associated with soils (Al, Cr, Fe, Na, Ni and S) have increased over the study period, while nutrient and pollutant elements (Cu, K, P...

Protozoal and epitheliocystis-like infections in the introduced bluestripe snapper (Lutjanus kasmira) in Hawaii Protozoal and epitheliocystis-like infections in the introduced bluestripe snapper (Lutjanus kasmira) in Hawaii

The bluestripe snapper, or taape, was introduced into Hawaii in the 1950s and has since become very abundant throughout the archipelago. As part of a health survey of reef fish in Hawaii, we necropsied 120 taape collected from various coastal areas south of Oahu and examined fish histology for extraintestinal organisms. Forty-seven percent of taape were infected with an apicomplexan...

Avian cholera in Southern Great Petrel (Macronectes giganteus) from Antarctica Avian cholera in Southern Great Petrel (Macronectes giganteus) from Antarctica

A southern giant petrel (Macronectes giganteus) was found dead at Potter Peninsula, King George Island, South Shetland, Antarctica. The adult male was discovered approximately 48 hr after death. Macroscopic and microscopic lesions were compatible with avian cholera and the bacterium Pasteurella multocida subsp. gallicida, serotype A1 was isolated from lung, heart, liver, pericardial sac...

Science for avian conservation: Priorities for the new millennium Science for avian conservation: Priorities for the new millennium

Over the past decade, bird conservation activities have become the preeminent natural resource conservation effort in North America. Maturation of the North American Waterfowl Management Plan (NAWMP), establishment of Partners in Flight (PIF), and creation of comprehensive colonial waterbird and shorebird conservation plans have stimulated unprecedented interest in, and funding for, bird
