Evaluating the use of hair as a non-invasive indicator of trace mineral status in woodland caribou (Rangifer tarandus caribou)

Naima Jutha, Claire Jardine, Helen Schwantje, Jesper Mosbacher, David Kinniburgh & Susan Kutz
Trace mineral imbalances can have significant effects on animal health, reproductive success, and survival. Monitoring their status in wildlife populations is, therefore, important for management and conservation. Typically, livers and kidneys are sampled to measure mineral status, but biopsies and lethal-sampling are not always possible, particularly for Species at Risk. We aimed to: 1) determine baseline mineral levels in Northern Mountain caribou (Rangifer tarandus caribou; Gmelin, 1788) in northwestern British Columbia, Canada, and 2) determine...

Data from: Flowering overlap and floral trait similarity help explain the structure of pollination network

Víctor Parra-Tabla, Alexander Suárez-Mariño, Gerardo Arceo-Gómez & Cristopher Albor
Co-flowering communities are usually characterized by high plant generalization but knowledge of the underlying factors leading to high levels of generalization and pollinator sharing, and how these may contribute to network structure is still limited. Flowering phenology and floral trait similarity are considered among the most important factors determining plant generalization and pollinator sharing. However, these have been evaluated independently even though they can act in concert with each other. Moreover, the importance of flowering...

Foraging behaviour data for sympatric Ateles geoffroyi, Alouatta palliata, and Cebus imitator

Carrie Veilleux, Amanda Melin, Chihiro Hiramatsu, Karem Sánchez‐Solano, Shasta Webb, Rachel Williamson, Megan Mah, Evin Murillo-Chacon, Colleen Schaffner, Laura Hernández‐Salazar, Filippo Aureli & Shoji Kawamura
Senses form the interface between animals and environments, and their form and function provide a window into the ecology of past and present species. However, research on the senses used during foraging (e.g. smell, vision, touch, taste) by wild terrestrial frugivores is sparse. Here, we combine 26,094 fruit foraging sequences recorded from three wild, sympatric primates (Cebus imitator, Ateles geoffroyi, Alouatta palliata) with data on within- and between-species variation in colour vision, olfaction, taste, and...

Data from: Landscape complementation is a driver of bumble bee (Bombus sp.) abundance in the Canadian Rocky Mountains

Danielle Clake, Sean Rogers & Paul Galpern
Context: Land use change is a major factor influencing biodiversity, but the mechanisms that drive species losses require further examination. Habitat loss often reduces biodiversity, but habitat fragmentation can increase biodiversity when examined independently. Processes driving this pattern remain largely unclear. Objectives: We aimed to determine the effects of habitat fragmentation on bumble bee populations after controlling for habitat amount, and to examine possible mechanisms behind observed effects. Methods: We sampled 22 species of bumble...

On the genetic architecture of rapidly adapting and convergent life history traits in guppies

James Whiting, Josephine Paris, Paul Parsons, Sophie Matthews, Yuridia Reynoso, Kimberly Hughes, David Reznick & Bonnie Fraser
The genetic basis of traits shapes and constrains how adaptation proceeds in nature; rapid adaptation can be facilitated by polygenic traits, which subsequently provide multiple, redundant, genetic routes to adaptive phenotypes, reducing re-use of the same genes (genetic convergence). Guppy life history traits evolve rapidly and convergently among natural high- (HP) and low-predation (LP) environments in northern Trinidad. This system has been studied extensively at the phenotypic level, but little is known about the underlying...

A deglacial hazard cascade exemplified by the landslide, tsunami and outburst flood at Elliot Creek, Southern Coast Mountains, British Columbia, Canada

Marten Geertsema, Brian Menounos, Gemma Bullard, Jonathan Carrivick, John Clague, Chunli Dai, Davide Donati, Goran Ekstrom, Jennifer Jackson, Patrick Lynett, Manuele Pichierri, Andy Pon, Dan Shugar, Doug Stead, Justin Del Bel Belluz, Pierre Friele, Ian Giesbrecht, Derek Heathfield, Tom Millard, Sasha Nasonova, Andrew Schaeffer, Brent Ward, Darren Blaney, Erik Blaney, Camille Brillon … & Meghan Sharp
We describe and model the evolution of a recent landslide and outburst flood in the southern Coast Mountains, British Columbia, Canada. About 18 Mm3 of rock descended 1000 m from a steep valley wall and traveled across the toe of a glacier before entering a 0.6 km2 glacier lake and producing a >100-m high wave. Water overtopped the lake outlet and scoured a 10-km long channel before depositing debris on a 2 km2 fan below...

TRPM8 thermosensation in ectotherms mediates both skin colour and locomotor performance responses to cold temperature

Gabriel Bertolesi, Hannan Malik & Sarah McFarlane
Thermoregulation is a homeostatic process to maintain an organism’s internal temperature within a physiological range compatible with life. In ectotherms, body temperature fluctuates with that of the environment, with both physiological and behavioral responses employed to modify body temperature. Changing skin colour/reflectance and locomotor activity are both well-recognized temperature regulatory mechanisms, but little is known of the participating thermosensor/s. We find that Xenopus laevis tadpoles put in the cold exhibit a temperature-dependent and rapid melanosome...

Rhesus macaque cone ratio heritability

Rachel A. Munds, Eve Cooper, Mareike C. Janiak, Linh Gia Lam, Alex DeCasien, Sam Baumann Surratt, Mike Montague, Melween Martinez, Shoji Kawamura, James P. Higham & Amanda D. Melin
A defining feature of catarrhine primates is uniform trichromacy – the ability to distinguish red (long; L), green (medium; M), and blue (short; S) wavelengths of light. While the tuning of photoreceptors is conserved, the ratio of L:M cones in the retina is variable within and between species, with human cone ratios differing from other catarrhines. Yet, the sources and structure of variation in cone ratios are poorly understood, precluding a broader understanding of color...

Flower color and flowering phenology mediate plant-pollinator interaction assembly in a diverse co-flowering community

Gerardo Arceo-Gomez, Cristopher Albor-Pinto, Tia-Lynn Ashman, Amber Stanley & Carlos Martel
Uncovering the role of competition and facilitation in community assembly is central for developing a predictive understanding of the forces that organize biodiversity. Standard trait-based approaches however rely on detection of only one assembly mechanism (competition or facilitation) along a single trait even though pollinator-mediated plant-plant interactions can be structured along multiple phenotypic, phenological and ecological traits. We evaluated plant species distribution along multiple phenotypic and ecological traits (flower color, flowering time, pollinator sharing) and...

Hemotological and morphometric measurements from geladas

Kenneth L. Chiou, Mareike C. Janiak, India A. Schneider-Crease, Sharmi Sen, Ferehiwot Ayele, Idrissa S. Chuma, Sascha Knauf, Alemayehu Lemma, Anthony V. Signore, Anthony M. D’Ippolito, Belayneh Abebe, Abebaw Azanaw Haile, Fanuel Kebede, Peter J. Fashing, Nga Nguyen, Colleen McCann, Marlys L. Houck, Jeffrey D. Wall, Andrew S. Burrell, Christina M. Bergey, Jeffrey Rogers, Jane E. Phillips-Conroy, Clifford J. Jolly, Amanda D. Melin, Jay F. Storz … & Noah Snyder-Mackler
Primates have adapted to numerous environments and lifestyles but very few species are native to high elevations. Here, we investigated high-altitude adaptations in the gelada (Theropithecus gelada), a monkey endemic to the Ethiopian Plateau. We examined genome-wide variation in conjunction with measurements of haematological and morphological traits. Our new gelada reference genome is highly intact and assembled at chromosome-length levels. Unexpectedly, we identified a chromosomal polymorphism in geladas that could potentially contribute to reproductive barriers...

Decline effects are rare in ecology: a meta-meta-analysis

Jeremy Fox & Laura Costello
The scientific evidence base on any given topic changes over time as more studies are published. Currently, there is widespread concern about non-random, directional changes over time in the scientific evidence base associated with many topics. In particular, if studies finding large effects (e.g., large differences between treatment and control means) tend to get published quickly, while small effect sizes tend to get published slowly, the net result will be a decrease over time in...

Evolution of thermal physiology alters the projected range of threespine stickleback under climate change

Sara Wuitchik, Stephanie Mogensen, Tegan Barry, Antoine Paccard, Heather Jamniczky, Rowan Barrett & Sean Rogers
Species distribution models (SDMs) are widely used to predict range shifts but could be unreliable under climate change scenarios because they do not account for evolution. The thermal physiology of a species is a key determinant of range and thus incorporating thermal trait evolution into SDMs might be expected to alter projected ranges. We identified a genetic basis for physiological and behavioural traits that evolve in response to temperature change in natural populations of threespine...

Data from: Targeted genome-wide SNP genotyping in feral horses using non-invasive fecal swabs

Stefan Gavriliuc, Salman Reza, Chanwoori Jeong, Philip McLoughlin & Jocelyn Poissant
The development of high-throughput sequencing has prompted a transition in wildlife genetics from using microsatellites toward sets of Single Nucleotide Polymorphisms (SNPs). However, genotyping large numbers of targeted SNPs using non-invasive samples remains challenging due to relatively large DNA input requirements. Recently, target enrichment has emerged as a promising approach requiring little template DNA. We assessed the efficacy of Tecan Genomics’ Allegro Targeted Genotyping (ATG) for generating genome-wide SNP data in feral horses using DNA...

Supporting CT Data for: Two exceptionally preserved juvenile specimens of Gorgosaurus libratus (Tyrannosauridae, Albertosaurinae) provide new insight into the timing of ontogenetic changes in tyrannosaurids

Jared Voris, Darla Zelenitsky, Francois Therrien, Ryan Ridgely, Philip Currie & Lawrence Witmer
Known from dozens of specimens discovered since the early 20th century, Gorgosaurus libratus has arguably contributed more than any other taxon to our understanding of the life history of tyrannosaurids. However, juvenile material for this taxon is rare. Here, we describe two small, articulated Gorgosaurus specimens (skull lengths of ~500 mm) that help advance our knowledge of the anatomy and ontogeny of this taxon and of tyrannosaurids in general. The new specimens exhibit hallmark juvenile...

Specimen list and landmark coordinates for the palate of early salamanders

Jia Jia, Guangzhao Li & Ke-Qin Gao
Ecological preferences and life history strategies have enormous impacts on the evolution and phenotypic diversity of salamanders, but the yet established reliable ecological indicators hinder investigations on the paleobiology of early salamanders. Here we statistically demonstrate using geometric morphometric analysis that both the shape of the palate and many non-shape variables particularly associated with vomerine teeth are ecologically informative in early stem- and basal crown-group salamanders. The morphology of the palate is heavily impacted by...

Commodity canola insect visitation

Samuel Robinson, Shelley Hoover, Stephen Pernal & Ralph Cartar
These data were used in a simulation study to examine how honey bees distribute themselves across foraging landscapes. The ideal-free distribution and central-place foraging are important ecological models that can explain the distribution of foraging organisms in their environment. However, this model ignores distance-based foraging costs from a central place (hive, nest), while central-place foraging ignores competition. Different foraging currencies and cooperation between foragers also create different optimal distributions of foragers, but are limited to...
