Underwater hearing in sea ducks with applications for reducing gillnet bycatch through acoustic deterrence Underwater hearing in sea ducks with applications for reducing gillnet bycatch through acoustic deterrence
As diving foragers, sea ducks are vulnerable to underwater anthropogenic activity, including ships, underwater construction, seismic surveys and gillnet fisheries. Bycatch in gillnets is a contributing source of mortality for sea ducks, killing hundreds of thousands of individuals annually. We researched underwater hearing in sea duck species to increase knowledge of underwater avian...

Towards critical white ice conditions in lakes under global warming Towards critical white ice conditions in lakes under global warming
The quality of lake ice is of uppermost importance for ice safety and under-ice ecology, but its temporal and spatial variability is largely unknown. Here we conducted a coordinated lake ice quality sampling campaign across the Northern Hemisphere during one of the warmest winters since 1880 and show that lake ice during 2020/2021 commonly consisted of unstable white ice, at times...

Review of harmful algal blooms effects on birds with implications for avian wildlife in the Chesapeake Bay region Review of harmful algal blooms effects on birds with implications for avian wildlife in the Chesapeake Bay region
The Chesapeake Bay, along the mid-Atlantic coast of North America, is the largest estuary in the United States and provides critical habitat for wildlife. In contrast to point and non-point source release of pesticides, metals, and industrial, personal care and household use chemicals on biota in this watershed, there has only been scant attention to potential exposure and effects of...

Level and pattern of overstory retention shape the abundance and long-term dynamics of natural and created snags Level and pattern of overstory retention shape the abundance and long-term dynamics of natural and created snags
Standing dead trees, or snags, serve myriad functions in natural forests, but are often scarce in forests managed for timber production. Variable retention (VR), the retention of live and dead trees through harvest, has been adopted globally as a less intensive form of regeneration harvest. In this study, we explore how two key elements of VR systems — level (amount) and spatial pattern...

Demographic and environmental correlates of home ranges and long-distance movements of Mohave ground squirrels Demographic and environmental correlates of home ranges and long-distance movements of Mohave ground squirrels
Space use by mammals can differ among age-classes, sexes, or seasons, and these processes are recognized as adaptive behavioral strategies. Semi-fossorial ground squirrels, in particular, have shown age- and sex-specific patterns in their aboveground movement behaviors. We studied space use of Mohave ground squirrels (Xerospermophilus mohavensis) at the Freeman Gulch study site in the...

A serological survey of Francisella tularensis exposure in wildlife on the Arctic Coastal Plain of Alaska A serological survey of Francisella tularensis exposure in wildlife on the Arctic Coastal Plain of Alaska
Tularemia is an infectious zoonotic disease caused by one of several subspecies of Francisella tularensis bacteria. Infections by F. tularensis are common throughout the northern hemisphere and have been detected in more than 250 wildlife species. In Alaska, US, where the pathogen was first identified in 1938, studies have identified F. tularensis antibodies in a diverse suite of taxa...

Diet composition and overlap of larval pallid sturgeon and shovelnose sturgeon from the upper Missouri River, USA Diet composition and overlap of larval pallid sturgeon and shovelnose sturgeon from the upper Missouri River, USA
Early life stages of pallid sturgeon Scaphirhynchus albus are rarely collected, and thus information on their biology and ecology is extremely limited. We sampled 75 larval pallid sturgeon (25-110 mm) and 148 larval shovelnose sturgeon S. platorynchus (15-95 mm) by trawl from the upper Missouri River (USA) in 2019. Stomach contents were identified to compare food use and diet overlap...

Getting ahead of flash drought: From early warning to early action Getting ahead of flash drought: From early warning to early action
Flash droughts, characterized by their unusually rapid intensification, have garnered increasing attention within the weather, climate, agriculture, and ecological communities in recent years due to their large environmental and socioeconomic impacts. Because flash droughts intensify quickly, they require different early warning capabilities and management approaches than are typically...

Autumn precipitation: The competition with Santa Ana winds in determining fire outcomes in southern California Autumn precipitation: The competition with Santa Ana winds in determining fire outcomes in southern California
Background: California’s South Coast has experienced peak burned area in autumn. Following typically dry, warm summers, precipitation events and Santa Ana winds (SAWs) each occur with increasing frequency from autumn to winter and may affect fire outcomes. Aims: We investigate historical records to understand how these counteracting influences have affected fires. Methods: We defined...

Actionable social science can guide community level wildfire solutions. An illustration from North Central Washington, US Actionable social science can guide community level wildfire solutions. An illustration from North Central Washington, US
In this study we illustrate the value of social data compiled at the community scale to guide a local wildfire mitigation and education effort. The four contiguous fire-prone study communities in North Central Washington, US, fall within the same jurisdictional fire service boundary and within one US census block group. Across the four communities, similar attitudes toward wildfire were...

Microbiomes associated with avian malaria survival differ between susceptible Hawaiian honeycreepers and sympatric malaria-resistant introduced birds Microbiomes associated with avian malaria survival differ between susceptible Hawaiian honeycreepers and sympatric malaria-resistant introduced birds
Of the estimated 55 Hawaiian honeycreepers (subfamily Carduelinae) only 17 species remain, nine of which the International Union for Conservation of Nature considers endangered. Among the most pressing threats to honeycreeper survival is avian malaria, caused by the introduced blood parasite Plasmodium relictum, which is increasing in distribution in Hawaiʻi as a result of climate change

The first assessment of the genetic diversity and structure of the endangered West Indian manatee in Cuba The first assessment of the genetic diversity and structure of the endangered West Indian manatee in Cuba
The coastal waters of Cuba are home to a small, endangered population of West Indian manatee, which would benefit from a comprehensive characterization of the population’s genetic variation. We conducted the first genetic assessment of Cuban manatees to determine the extent of the population's genetic structure and characterize the neutral genetic diversity among regions within the...
