No evidence for future planning in Canada Jays (Perisoreus canadensis)

Robert Martin, Glynis Martin, William Roberts & David Sherry
In the past 20 years, research in animal cognition has challenged the belief that complex cognitive processes are uniquely human. At the forefront of these challenges has been research on mental time travel and future planning in jays. We tested whether Canada Jays (Perisoreus canadensis) demonstrated future planning, using a procedure that had previously produced evidence of future planning in California Scrub-Jays (Aphelocoma californica). Future planning in this procedure is caching in locations where the...

Rapid recovery by fat- and muscle-depleted Blackpoll Warblers following trans-oceanic migration is driven by time-minimization

Nicholas J. Bayly, Kenneth V. Rosenberg, Ryan Norris, Philip D. Taylor & Keith A. Hobson
Non-stop endurance flights are a defining characteristic of many long-distance migratory birds but subsequent recovery phases are not typically distinguished from fueling phases (collectively ‘stopovers’), despite endurance flights inducing marked physiological changes including flight muscle atrophy and gastrointestinal tract reductions. Here, we hypothesize that recovery requires unique behavioral adaptations, leading to departures from the predictions of optimal migration theory for time-minimizing migrants. We predict that recovering birds will 1) select (moist) food-rich habitats on arrival;...

Chinook salmon environmental data and allele frequency matrix

Yara Alshwairikh, Rebekah Horn, Travis Seaborn, Shawn Narum, Lisette Waits, William Swain, Steve Stephens-Cardenas, Jenny Olsson & Shayla Kroeze
Many species that undergo long breeding migrations, such as anadromous fishes, face highly heterogeneous environments along their migration corridors and at their spawning sites. These environmental challenges encountered at different life stages may act as strong selective pressures and drive local adaptation. However, the relative influence of environmental conditions along the migration corridor compared to the conditions at spawning sites on driving selection is still unknown. In this study, we performed genome-environment associations (GEA) to...

Cold tolerance of laboratory-reared Asian longhorned beetles

Alex Torson, Meng Lei Zhang, Kevin Ong, Lamees Mohammad, Adam Smith, Daniel Doucet, Amanda Roe & Brent Sinclair
Low winter temperatures in temperate climates can limit the success of non-native species. The Asian longhorned beetle, Anoplophora glabripennis, is an invasive wood-boring pest of hardwood trees in North America and Europe. Native A. glabripennis populations are spread across several climate zones in China and the Korean Peninsula and are likely to encounter low temperatures in at least some of this range. Understanding the lethal limits of the overwintering life stages of A. glabripennis is...
