Primary fungal diseases in marine mammals are rare. Mucormycosis, a disease caused by fungi of the order Mucorales, has been documented few cetaceans and pinnipeds. In 2012, first case mucormycosis Pacific Northwest was dead stranded harbor porpoise (Phocoena phocoena) Washington state. Since then, detected total 21 mammals; fifteen porpoises, five seals (Phoca vitulina), one southern resident killer whale (Orcinus orca). Infected animals were predominately found inland waters British...
The harbor seal (Phoca vitulina richardii) population in the Salish Sea has been at equilibrium since mid-1990s. This stable of marine mammals resides relatively close to shore near a large human and offers novel opportunity evaluate whether disease acts density-dependent manner limit growth. We conducted retrospective analysis stranding necropsy findings San Juan Islands sub-population assess age-related trends causes mortality. Between January 1, 2002 December 31, 2018, we detected 882...
Abstract Spatial analyses of marine mammal stranding data can be used to identify patterns and improve surveillance monitoring. Using ArcGIS SaTScan, we analyzed 12 years (2002–2014) dead beachcast mammals from San Juan County, Washington, better understand carcass deposition. We plotted the locations for 631 aggregated strandings into 1,000 m segments shoreline. “Hot spots” included beach with significantly higher deposition according Getis‐Ord Gi* statistic in or that were encompassed by...
The pervasive use of antibiotics in human medicine, veterinary and agriculture can result a significant increase the spread environmental persistence antibiotic resistance marine ecosystems. This study describes presence distribution antibiotic-resistant bacteria Salish Sea harbor seals (Phoca vitulina) porpoises (Phocoena phocoena) evaluates species, age class, geographic differences patterns. Isolates from 95 dead-stranded animals (74 seals/21 porpoises) were tested for to suite 15...
Studying patterns in marine mammal stranding cases can provide insight into changes population health, abundance, and distribution. Cetaceans along the United States West coast strand for a wide variety of reasons, including disease, injury, poor nutritional status, all which may be caused by both natural anthropogenic factors. Examining potential drivers these reveal how populations respond to their habitat, notably oceanographic variability activities. In this study, we aim synthesize...
The prevalence of Type 1 Diabetes (T1D) among youth is increasing worldwide. Mobile phones, particularly mHealth applications, can potentially improve youth's management this chronic condition. However, the design these services rarely accounts for users in low and middle-income countries (LMICs). In paper, we investigate factors that influence use mobile phones managing T1D rural urban Kenya. Our analysis draws from 58 interviews conducted with (between ages 11 18 years old), their...
Approximately 5,000 Pacific harbor seals (Phoca vitulina richardii) reside year-round in San Juan County (SJC), Washington (US) the center of binational Salish Sea. We retrospectively analyzed total cadmium (Cd), copper (Cu), iron (Fe), mercury (Hg), magnesium (Mg), manganese (Mn), lead (Pb), selenium (Se), and zinc (Zn) livers dead stranded (n=57) collected SJC between 2009 2012 to identify age-related regional patterns trace element exposure. Consistent with prior studies contaminants...
Abstract Endangered Southern Resident killer whales ( Orcinus orca ) are fish‐eaters that preferentially prey on adult Chinook salmon Oncorhynchus tshawytscha ). Despite being specialists, individuals from all three whale pods (J, K, L) have been observed harassing and killing porpoises (family Phocoenidae) without consuming them. Retrospectively, we identified analyzed 78 episodes of between 1962 2020, which 28 resulted in the porpoise's death (“phocoenacide”). Fifty‐six involved harbor...
Postmortem data for harbor seals (Phoca vitulina richardsii) in the Salish Sea were analyzed epidemiologic trends congenital diseases. Cleft palate, cleft lips, or both (n=8) and cardiac defects (n=5) most common abnormalities, followed by cases with multiple (n=4). No temporal spatial clusters of seen from 2003 to 2019, during which time monitoring effort was consistent. Cases could not be linked specific causes such as environmental contamination maternal malnutrition. Our study suggests...
The Salish Sea supports several baleen whale species, including humpback ( Megaptera novaeangliae ), gray Eschrichtius robustus ) and minke whales (Balaenoptera acutorostrata ). With the exception of whales, these species were decimated by commercial whaling in 1900s. Because recovery populations is monitored on broad spatial scales determined stocks or populations, their use ecosystem not well documented understood. We collated 17,436 opportunistic sighting reports to assess patterns...
Increased exposure to anthropogenic activities often results in animals developing higher tolerance that would otherwise disturb them. Although this response is sometimes viewed as a beneficial survival mechanism, habituation human may lead negative consequences, such decreased predator aversion. Due their healthy population status, the numerous and varied locations of haul-out sites anti-predatory bald eagles, harbor seals Salish Sea are an ideal study system answer questions concerning...
Documenting human impacts on marine mammals is critical for understanding and mitigating harm. Although propeller strike injuries in small are often debilitating fatal, little known about the occurrence or demographics of these types pinniped populations. Using data stranded harbor seals (Phoca vitulina) Salish Sea from 2002–19, we identified 27 cases fatal strikes. Weaned pups were most frequently affected (64% cases) with a much higher rate strikes than expected age class. they do...
A single incident of attempted predation a Harbor Seal (Phoca vitulina) pup by an American Mink (Neovision vision) was observed on Blakely Island, Washington in 2015. San Juan County Marine Mammal Stranding Network members responded, investigated the event, and performed necropsy seal. Predation is most parsimonious explanation for attack due to Mink's opportunistic predatory tendencies vulnerability moribund Seal. With both populations documented as abundant or at carrying capacity,...
