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;...

Data from: Stopover refueling, movement, and departure decisions in the White-throated Sparrow: the influence of intrinsic and extrinsic factors during spring migration

Andrew T. Beauchamp, Christopher G. Guglielmo & Yolanda E. Morbey
1. Differential migration timing between sex or age classes are examples of how migratory movement strategies can differ among sub-groups within a population. However, in songbirds, evidence for intrinsic differences in en route migratory behavior is often mixed, suggesting that the local environmental context may play a role in accentuating or diminishing patterns. 2. We evaluated how multiple intrinsic and extrinsic variables influenced refueling rates, local movement behavior, and departure decisions in the White-throated Sparrow...

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...

Exploring the inclusion of dental providers on interprofessional healthcare teams treating patients with chronic obstructive pulmonary disease: a rapid review

Navia Novosel, Greta Fratarcangeli, Jasdip Randhawa, Olivia Novosel & Shannon Sibbald
Chronic obstructive pulmonary disease (COPD) is the third leading cause of death in the world. Emerging concepts like One Health, integrated models for COPD, and associations between oral and respiratory health are innovative ways to approach COPD treatment. This study explored contemporary evidence on the inclusion of dental providers on interprofessional healthcare teams treating patients with COPD. The first objective was to explore the current state of interprofessional care for COPD treatment, and the second...

Data from: Neotropical migratory and resident birds occurring in sympatry during winter have distinct haemosporidian parasite assemblages

Leticia Soares, Steven. Latta & Robert. E. Ricklefs
Aim: We compared the parasite assemblages of over-wintering migratory birds and permanent residents on the wintering grounds. We determined whether parasite sharing between migratory and resident birds is influenced by host phylogenetic relatedness. We then inferred whether migratory birds transport haemosporidian parasite lineages between the breeding and wintering grounds. Location: Sierra de Bahoruco National Park, Dominican Republic, Hispaniola Taxa: Migratory and resident birds (primarily Aves: Passeriformes) and their haemosporidian parasites (order Haemosporida, Plasmodium, Haemoproteus and...

Data from: Mallard resource selection trade‐offs in a heterogeneous environment during autumn and winter

Matthew D. Palumbo, Scott A. Petrie, Michael Schummer, Benjamin D. Rubin & Simon Bonner
Animals select resources to maximize fitness but associated costs and benefits are spatially and temporally variable. Differences in wetland management influence resource availability for ducks and mortality risk from duck hunting. The local distribution of the Mallard (Anas platyrhynchos) is affected by this resource heterogeneity and variable risk from hunting. Regional conservation strategies primarily focus on how waterfowl distributions are affected by food resources during the nonbreeding season. To test if Mallard resource selection was...

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...

Metabolic cost of freeze-thaw and source of CO2 production in the freeze-tolerant cricket Gryllus veletis

Adam Smith, Kurtis Turnbull, Julian Moulton & Brent Sinclair
Freeze-tolerant insects can survive the conversion of a substantial portion of their body water to ice. While the process of freezing induces active responses from some organisms, these responses appear absent from freeze-tolerant insects. Recovery from freezing likely requires energy expenditure to repair tissues and re-establish homeostasis, which should be evident as elevations in metabolic rate after thaw. We measured carbon dioxide (CO2) production in the spring field cricket (Gryllus veletis) as a proxy for...

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...
