Climate-related drivers of migratory bird health in the south-central USA. [PDF]
ABSTRACT Migratory birds are species of concern that play important ecological roles while also supporting recreational opportunities for the hunting and birdwatching public. Direct and indirect effects of climate variability, extremes, and change on migratory bird health manifest at the individual, population, species, and community levels.

Maximizing the potential for living cell banks to contribute to global conservation priorities
A lack of standardized information on the species represented in global cryobanks, and inconsistent prioritization of species for future sampling, hinder the conservation potential of cryobanking. Here we show that 965 species, including 5% of all International Union for Conservation of Nature Red List “Threatened” amphibians, birds, mammals, and ...

Mechanisms of group‐hunting in vertebrates
ABSTRACT Group‐hunting is ubiquitous across animal taxa and has received considerable attention in the context of its functions. By contrast much less is known about the mechanisms by which grouping predators hunt their prey. This is primarily due to a lack of experimental manipulation alongside logistical difficulties quantifying the behaviour of ...

Abstract Bolbophorus damnificus is a digenetic trematode causing significant economic losses within the United States commercial catfish industry. The indirect life cycle is complex, requiring piscivorous birds, aquatic snails, and fish to complete.

Feather function and the evolution of birds
ABSTRACT The ability of feathers to perform many functions either simultaneously or at different times throughout the year or life of a bird is integral to the evolutionary history of birds. Many studies focus on single functions of feathers, but any given feather performs many functions over its lifetime. These functions necessarily interact with each

Respiration and energetics of embryonic development in a large altricial bird, the Australian pelican (Pelecanus conspicillatus) [PDF]
We examined whether the previously reported low cost of embryonic development in pelicans could be attributed to a more efficient conversion of egg energy to hatchling tissues as a result of high initial egg water content, low embryonic metabolic rate ...

Cost of regulations on US catfish farms
Abstract Understanding the economic effects of regulations on US aquaculture farms provides insights into which compliance costs create the greatest compliance burden on farms. This can further guide strategies to improve the efficiency of regulatory frameworks and potentially reduce on‐farm compliance costs while maintaining adequate oversight.

Integrating data types to estimate spatial patterns of avian migration across the Western Hemisphere
Abstract For many avian species, spatial migration patterns remain largely undescribed, especially across hemispheric extents. Recent advancements in tracking technologies and high‐resolution species distribution models (i.e., eBird Status and Trends products) provide new insights into migratory bird movements and offer a promising opportunity for ...

Surveillance for West Nile Virus in American White Pelicans, Montana, USA, 2006–2007
West Nile virus (WNV)–associated deaths of American white pelican (Pelecanus erythrorhynchos) chicks have been recognized at various nesting colonies in the United States since 2002. We evaluated American white pelican nesting colonies in Sheridan County,
