Epizootiologic studies of avian vacuolar myelinopathy in waterbirds Epizootiologic studies of avian vacuolar myelinopathy in waterbirds

Epizootic avian vacuolar myelinopathy (AVM) was first recognized as a neurologic disease in bald eagles (Haliaeetus leucocephalus) and American coots (Fulica americana) in Arkansas, USA in 1994 and 1996, respectively, but attempts to identify the etiology of the disease have been unsuccessful to date. Between 1998 and 2001, wing clipped sentinel birds (wild American coots and game farm...

Toxoplasmosis in three species of native and introduced Hawaiian birds Toxoplasmosis in three species of native and introduced Hawaiian birds

Toxoplasma gondii was found in endemic Hawaiian birds, including 2 nene geese (Nesochen sandvicensis), 1 red-footed booby (Sula sula), and an introduced bird, the Erckels francolin (Francolinus erckelii). All 4 birds died of disseminated toxoplasmosis; the parasite was found in sections of many organs, and the diagnosis was confirmed by immunohistochemical staining with anti–T. gondii...

Epizootiology of sixty-four amphibian morbidity and mortality events in the USA, 1996-2001 Epizootiology of sixty-four amphibian morbidity and mortality events in the USA, 1996-2001

A total of 44 amphibian mortality events and 20 morbidity events were reviewed retrospectively. The most common cause of amphibian mortality events was infection by ranaviruses (Family: Iridoviridae). Ranavirus epizootics have abrupt onset and affect late-stage larvae and recent metamorphs. Mortality events due to ranavirus infections affected only widespread and abundant amphibian...

Application of diagnostic tests for mycoplasmal infections of desert and gopher tortoises with management recommendations Application of diagnostic tests for mycoplasmal infections of desert and gopher tortoises with management recommendations

Mycoplasmosis is a transmissible upper respiratory tract disease that has affected plans for management and conservation of wild desert and gopher tortoises in the United States. Although impact of mycoplasmosis on populations of desert and gopher tortoises is unknown, increased prevalence of seropositive animals as well as field observations of clinically ill tortoises have occurred in

Patterns of lichen diversity in Yellowstone National Park Patterns of lichen diversity in Yellowstone National Park

We here report 359 species in 103 genera from Yellowstone National Park. We found 71.3% of the total number of species in Picea engelmannii forests and 57.4% of the total number in Pseudotsuga menziesii stands. This compares to 42.3% of the species in Pinus contorta and 37.0% of the species in Pinus contorta/Pinus albicaulis stands. The presence of old Pseudotsuga menziesii and mature...

Wildlife disease in the Colorado Delta as an indicator of ecosystem health Wildlife disease in the Colorado Delta as an indicator of ecosystem health

Ecosystem health and management are relatively new paradigms for environmental management (Costanza et al., 1992) and will be continually redefined and reevaluated relative to their purpose and utility in serving human society (Costanza et al., 1992; Sutter, 1993; Grumbine, 1994; Lackey, 1998, 1999). The stimulus for ecosystem management is often associated with sustaining or restoring...

Preface Preface

This issue of Hydrobiologia brings together a series of papers resulting from an intensified effort to describe the current status of the physical and biological conditions present at California's Salton Sea. Most of the studies were contract investigations that were part of a project initiated in January 1998 to pursue the improvement of environmental conditions at the Salton Sea. The...
