Dietary composition and fatty acid content of giant salmonflies (Pteronarcys californica) in two Rocky Mountain rivers

Michelle Briggs, Lindsey Albertson, Zach Maguire, Sophia Swart, Wyatt Cross, Cornelia Twining, Jeff Wesner, Colden Baxter & David Walters
Many aquatic invertebrates are declining or facing extinction from stressors that compromise physiology, resource consumption, reproduction, and phenology. However, the influence of these common stressors specifically on consumer-resource interactions for aquatic invertebrate consumers is only beginning to be understood. We conducted a field study to investigate Pteronarcys californica (i.e., the ‘giant salmonfly’), a large-bodied insect that is ecologically and culturally significant to rivers throughout the western U.S. We sampled gut contents and polyunsaturated fatty acid...

An early dog from Southeast Alaska supports a coastal route for the first dog migration into the Americas

Flavio Augusto Da Silva Coelho, Stephanie Gill, Crystal Tomlin, Timothy Heaton & Charlotte Lindqvist
The oldest confirmed remains of domestic dogs in North America are from mid-continent archeological sites dated ~9,900 calibrated years before present (cal BP). Although this date suggests that dogs may not have arrived alongside the first Native Americans, the timing and routes for the entrance of New World dogs are unclear. Here, we present a complete mitochondrial genome of a dog from Southeast Alaska, dated to 10,150 ± 260 cal BP. We compared this high-coverage...

Urban rooftop-nesting Common Nighthawk chicks tolerate high temperatures by hyperthermia with relatively low rates of evaporative water loss

Gretchen Newberry
Heat tolerance for many birds under climate and land use change scenarios could be compromised in the future. Common Nighthawks (Chordeiles minor) belong to the Caprimulgiformes, a generally heat-tolerant order, but few studies have assessed heat tolerance in Caprimulgiform chicks, which might be particularly susceptible to heat stress. In the Midwestern U.S., nighthawks primarily nest on flat graveled rooftops in urban areas, as natural nesting habitats are limited. Urban rooftop-nesting nighthawks are likely exposed to...
