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...

Supplementary material for: Neural effects of oxytocin and mimicry in frontotemporal dementia: A randomized cross-over study

Lindsay Oliver, Chloe Stewart, Kristy Coleman, James Kryklywy, Robert Bartha, Derek Mitchell & Elizabeth Finger
OBJECTIVE: Reduced empathy is one of the hallmark and untreatable symptoms of frontotemporal dementia (FTD). The objective of this study was to determine whether intranasal oxytocin, alone or in combination with instructed mimicry of facial expressions, would augment neural activity in patients with FTD in brain regions associated with empathy, emotion processing and the simulation network, as indexed by blood-oxygen-level dependent (BOLD) signal during functional magnetic resonance imaging (fMRI). METHODS: In a placebo-controlled, randomized cross-over...

Dormancy in laboratory-reared Asian longhorned beetles, Anoplophora glabripennis

Alex Torson, Meng Lei Zhang, Adam Smith, Lamees Mohammad, Kevin Ong, Daniel Doucet, Amanda Roe & Brent Sinclair
An insect’s capacity to survive winter is critical for range expansion in temperate regions. The Asian longhorned beetle (Anoplophora glabripennis) is a polyphagous wood-boring insect native to China and the Korean peninsula and poses a high risk of invasion in North America and Europe. It is unclear whether A. glabripennis enters diapause, which means that diapause cannot be included in assessments of the risk of this species invading forests in temperate regions. Using a laboratory...

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...

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...

Ecological and evolutionary drivers of hemoplasma infection and genotype sharing in a Neotropical bat community

Daniel Becker, Kelly Speer, Alexis Brown, Alex Washburne, Brock Fenton, Sonia Altizer, Daniel Streicker, Raina Plowright, Vladimir Chizhikov, Nancy Simmons & Dmitriy Volokhov
Most emerging pathogens can infect multiple species, underscoring the importance of understanding the ecological and evolutionary factors that allow some hosts to harbor greater infection prevalence and share pathogens with other species. However, our understanding of pathogen jumps is primarily based around viruses, despite bacteria accounting for the greatest proportion of zoonoses. Because bacterial pathogens in bats (Order: Chiroptera) can have conservation and human health consequences, studies that examine the ecological and evolutionary drivers of...

Responses of White-throated sparrows to simulated winter storm cues

Scott MacDougall-Shackleton & Andrea Boyer
These data were used in the publication "Increased frequency of exposure to simulated winter storm cues negatively affects white-throated sparrows (Zonotrichia albicollis)" Front. Ecol. Evol. | doi: 10.3389/fevo.2020.00222 Climate change is causing changes in weather patterns and more frequent extreme weather events. Although birds are often able to cope with and respond to inclement weather with physiological and behavioral responses, as weather events become more severe or frequent the adaptive coping responses of many species...

Supplementary Documentation - Epilepsy risk among survivors of intensive care unit hospitalization for sepsis

Tresah Antaya, Britney Allen, Lucie Richard, Salimah Shariff, Gustavo Saposnik & Jorge Burneo
Objective Our objectives were to determine if survivors of intensive care unit (ICU) hospitalizations with sepsis experience higher epilepsy risk than survivors of ICU hospitalizations without sepsis, and to identify sepsis survivors at highest risk. Methods We used linked, administrative healthcare databases to conduct a population-based, retrospective matched cohort study of adult Ontario residents discharged from an ICU between January 1, 2010 and December 31, 2015, identified using the Discharge Abstract Database. We used propensity...

Data from: Complex interactions between temperature, sexual signals, and mate choice in a desert-dwelling jumping spider

Erin Brandt, Malcolm Rosenthal & Damian Elias
Environmental context is a crucial factor that influences sexual communication systems. Particularly in ectotherms, which cannot metabolically regulate their body temperature, temperature has an outsized effect on these intraspecific interactions. Using a desert-dwelling jumping spider Habronattus clypeatus, we assessed how temperature impacts various parts of the male signal and female mate choice for the signal. These spiders have multimodal, temporally-structured courtship displays that begin with visual-only “sidling” displays and proceed to multimodal visual and vibratory...

Late Ordovician brachiopods from east-central Alaska, northwestern margin of Laurentia

Jisuo Jin & Robert Blodgett
A Late Ordovician brachiopod fauna from the Black River quadrangle (D-1 1:63,360 scale) of east-central Alaska comprises taxa typical of the Late Ordovician brachiopod fauna in the pericratonic epeiric seas of Laurentia, including Hesperorthis pyramidalis, Plaesiomys occidentalis, Eoplectodonta sp., Holtehdalina sp., Leptaena sp., Brevilamnulella minuta n. sp., Tcherskidium tenuicostatum n. sp., Rhynchotrema iowense, and Whitfieldella sp. The presence of Plaesiomys occidentalis and Tcherskidium tenuicostata n. sp. indicates a latest Katian age by correlation with similar...

Luciano Sposato, Sebastian Fridman, Maria Bres Bullrich, Amado Jimenez-Ruiz, Pablo Costantini, Palak Shah, Caroline Just, Daniel Vela-Duarte, Italo Linfante, Athena Sharifi-Razavi, Narges Karimi, Rodrigo Bagur, Derek Debicki, Teneille Emma Gofton & David A Steven
Objectives: To investigate the hypothesis that strokes occurring in patients with COVID-19 have distinctive features, we investigated stroke risk, clinical phenotypes, and outcomes in this population. Methods: We performed a systematic search resulting in 10 studies reporting stroke frequency among COVID-19 patients, which were pooled with one unpublished series from Canada. We applied random-effects meta-analyses to estimate the proportion of stroke among COVID-19. We performed an additional systematic search for cases series of stroke in...

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...

Data from: It’s not all about temperature: breeding success also affects nest design

Sophie Edwards, Tanya Shoot, Robert Martin, David Sherry & Susan Healy
There are numerous observational studies on intra-specific variation in avian nest building and a single experimental manipulation. The general consensus is that birds build nests in response to environmental conditions, but it is not clear whether such flexibility in nest building is reproductively advantageous. To test the relationship between building flexibility and reproductive success, we allowed captive zebra finches to build their first nest, using string, and to breed in temperature-controlled rooms held at 14oC...

Evening locomotor activity during stopover differs on pre-departure and departure days in free-living songbirds

Yolanda Morbey, Andrew Beauchamp, Simon Bonner & Gregory Mitchell
The length of time songbirds remain at a migratory stopover site is likely regulated by a daily stay/go decision informed by fat stores and weather conditions, but the finer-scale timing of this decision and associated pre-departure behaviours are still poorly understood. Using automated radiotelemetry of free-living songbirds captured at a migratory stopover site in spring, we tested whether individuals change their locomotor activity near sunset on their migratory departure day compared to their non-departure days....

Snow bunting respirometry data

Ryan O'Connor, Audrey Le Pogam, Kevin Young, Francis Robitaille, Emily Choy, Oliver Love, Kyle Elliott, Anna Hargreaves, Dominique Berteaux, Andrew Tam & François Vézina
1. Arctic animals inhabit some of the coldest environments on the planet and have evolved physiological mechanisms for minimizing heat loss under extreme cold. However, the Arctic is warming faster than the global average and how well Arctic animals tolerate even moderately high air temperatures (Ta) is unknown. 2. Using flow-through respirometry we investigated the heat tolerance and evaporative cooling capacity of snow buntings (Plectrophenax nivalis; ≈ 31g, N = 42), a cold specialist, Arctic...

Disentangling interactions among mercury, immunity, and infection in a Neotropical bat community

Daniel Becker, Kelly Speer, Jennifer Korstian, Dmitriy Volokhov, Hannah Droke, Alexis Brown, Catherene Baijnauth, Ticha Padgett-Stewart, Hugh Broders, Raina Plowright, Thomas Rainwater, Brock Fenton, Nancy Simmons & Matthew Chumchal
Contaminants such as mercury are pervasive and can have immunosuppressive effects on wildlife. Impaired immunity could be important for forecasting pathogen spillover risks, as many land-use changes that generate mercury contamination also bring wildlife into close contact with humans and domestic animals. However, the interactions among contaminants, immunity, and infection are difficult to study in natural systems, and empirical tests of possible directional relationships remain rare. We capitalized on extreme mercury variation in a diverse...
