Perfluorooctane sulfonate (PFOS) is a perfluorinated molecule that has recently been identified in the sera of nonindustrially exposed humans. In this study, 247 tissue samples from 15 species marine mammals collected Florida, California, and Alaskan coastal waters; northern Baltic Sea; Arctic (Spitsbergen); Sable Island Canada were analyzed for PFOS. PFOS was detected liver blood most locations including those waters. The greatest concentrations found 1520 ng/g wet wt bottlenose dolphin...
Escherichia albertii has been associated with diarrhea in humans but not disease or infection animals. However, December 2004, E. was found, by biochemical and genetic methods, to be the probable cause of death for redpoll finches (Carduelis flammea) Alaska. Subsequent investigation found this organism dead subclinically infected birds other species from North America Australia. Isolates Scotland, previously identified as coli O86:K61, also were shown albertii. Similar isolates humans,...
Abstract We studied moose ( Alces alces ) survival, physical condition, and abundance in a 3‐predator system western Interior Alaska, USA, during 2001–2007. Our objective was to quantify the effects of predator treatments on population dynamics by investigating changes survival while evaluating contribution potentially confounding covariates. In May 2003 2004, we reduced black bear Ursus americanus brown U. arctos numbers translocating bears ≥240 km from study area. Aircraft‐assisted take...
Abstract This article describes the first detections of disease due to natural infection with highly pathogenic avian influenza virus (HPAIv) H5N1 Eurasian lineage goose/Guangdong clade 2.3.4.4b in wild terrestrial mammals throughout United States during 2021-2022. Affected mammalian species include 50 red foxes ( Vulpes vulpes ), 6 striped skunks Mephitis mephitis 4 raccoons Procyon lotor 2 bobcats Lynx rufus Virginia opossums Didelphis virginiana 1 coyote Canis latrans fisher Pekania...
During 2010-2016, tick specimens were solicited from veterinarians, biologists, and members of the public in Alaska. Eight species ticks recorded domestic dogs. Some collected dogs with recent travel histories to other countries or U.S. states, which appears explain records not native Alaska such as Amblyomma americanum (L.) (lone star tick), Ixodes scapularis (Say) (blacklegged ricinus (L.). However, we Dermacentor variabilis (American dog tick) (and humans) both without history, suggesting...
The ongoing panzootic of highly pathogenic H5 clade 2.3.4.4b avian influenza (HPAI) spread to North America in late 2021, with detections HPAI viruses Alaska beginning April 2022. have since across the state, affecting many species wild birds as well domestic poultry and mammals. To better understand dissemination spatiotemporally among hosts adjacent regions, we compared genomes 177 confirmed detected during April-December Results suggest multiple viral introductions into between November...
ABSTRACT Understanding the drivers influencing ungulate population dynamics is crucial for developing conservation and management strategies to support wildlife health. Trace macro elements are vital growth, reproduction survival. Thus, trajectory of populations may be associated with element imbalances. Element concentrations can measured in hair, an increasingly recognised bio‐monitoring tool. However, a better understanding relevance wild needed. This study aimed assess if profiles hair...
Serologic data were examined to determine whether infectious disease may have played a role in the decline of Steller sea lions (Eumetopias jubatus) Gulf Alaska and Aleutian Islands, USA. Available published data, unpublished recent collections (1997–2000) compared reviewed. Data stratified by geography compare declining western Alaskan population Islands through eastern Prince William Sound increasing southeastern Alaska. Prevalences antibodies from 1970s early 1990s noted for Leptospira...
Fecal samples are often the only feasible means to assess diversity of parasites in wildlife; however, definitive identification egg or larval stages feces by morphology is rarely possible. We determined partial sequences from second internal transcribed spacer region (ITS-2) nuclear ribosomal DNA for first-stage, dorsal-spined larvae (DSL) caribou ( Rangifer tarandus (L., 1758), (Gmelin, 1788), grantii (Allen, 1902)), muskoxen Ovibos moschatus (Zimmermann, 1780), wardi Lydekker, 1900),...
Free-ranging caribou and moose populations in some regions of Alaska undergo periodic declines numbers. Caribou are managed by the state as valuable resources for not only sustenance subsistence, but also cultural heritage. Incidence prevalence diseases that may impact herd health recruitment from year to relevant management decisions aimed protect long-term viability these herds. Neospora caninum Toxoplasma gondii two apicomplexan parasites can cause neurologic disease abortions their...
Abstract Biting dog lice ( Trichodectes canis ) were first detected on wolves Canis lupus in Southcentral Alaska (USA) 1981 introduced via domestic dogs. Lice infestation expanded north wolf dispersal to the Tanana Flats of Interior December 2003. Effects this ectoparasite persistent with moderate severe clinical signs pediculosis lasting multiple generations. Our objectives evaluate extent within and develop a management program that limited further transmission. We implemented treatment...
From 1984 through 1992, staff at The Marine Mammal Center (TMMC, Sausalito, California, USA) examined 207 northern elephant seals (Mirounga angustirostris) with a condition of unknown etiology called seal skin disease (NESSD). lesions were characterized by patchy to extensive alopecia and hyperpigmentation, punctate or coalescing epidermal ulceration, occasionally, massive necrosis. Microscopic included ulcerative dermatitis hyperkeratosis, squamous metaplasia atrophy sebaceous glands. All...
