Infectious and parasitic diseases of the gray wolf and their potential effects on wolf populations in North America

Numerous infections and parasitic diseases have been reported for the gray wolf, including more than 10 viral, bacterial, and mycotic disease and more than 70 species of helminths and ectoparasites. However, few studies have documented the role of diseases in population dynamics. Disease can affect wolf populations directly by causing mortality or indirectly by affecting physiological and homeosta

Seasonal ingestion of toxic and nontoxic shot by Canada geese

We used rates of ingested shot and elevated blood-lead levels (≥0.18 ppm) to estimate the proportion of Canada geese (Branta canadensis) exposed to lead on 3 study areas in Manitoba, Minnesota, and Missouri. Lead exposure was prevalent on all areas and was common after the hunting season closed, when up to 15% of geese could have been exposed to lead shot. However, the proportion of steel shot ing

Wildlife disease and conservation in Hawaii: pathogenicity of avian malaria (Plasmodium relictum) in experimentally infected Iiwi (Vestiaria coccinea)

Native Hawaiian forest birds are facing a major extinction crisis with more than 75% of species recorded in historical times either extinct or endangered. Reasons for this catastrophe include habitat destruction, competition with non-native species, and introduction of predators and avian diseases. We tested susceptibility of Iiwi (Vestiaria coccinea), a declining native species, and Nutmeg Mannik

Hypopi (Acari: Hypoderatidae) of the wood stork (Aves: Ciconiiformes: Ciconiidae)

A new species is described and additional host records are presented for 2 other species of deutonymphs of the family Hypoderatidae from the subcutaneous adipose tissues of the wood stork, Mycteria americana L. Phalacrodectes (Phalacrodectes) mycteria n. sp. appears to share affinities with species from both pelicaniform and ciconiiform hosts, but it most closely resembles P. (P.) punctatissimus (

Heavy metals in seaducks and mussels from Misty Fjords National Monument in southeast Alaska

Quartz Hill, in Misty Fjords National Monument near Ketchikan, Alaska, is the site of a proposed molybdenum-producing mine. To provide baseline data for use in post-development comparisons, we analyzed tissues of Barrow's goldeneyes (Bucephala islandica), common mergansers (Mergus merganser), and blue mussels (Mytilus edulis) for seven heavy metals that could potentially be released into the envir

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 other life fo
