Data from: Metabolic recovery from drowning by insect pupae

H. Arthur Woods & Steven J. Lane
Many terrestrial insects live in environments that flood intermittently, and some life stages may spend days underwater without access to oxygen. We tested the hypothesis that terrestrial insects with underground pupae show respiratory adaptations for surviving anoxia and subsequently reestablishing normal patterns of respiration. Pupae of Manduca sexta were experimentally immersed in water for between 0 and 13 days. All pupae survived up to 5 days of immersion regardless of whether the water was aerated...

Data from: Vive la résistance: genome-wide selection against introduced alleles in invasive hybrid zones

Ryan P. Kovach, Brian K. Hand, Paul A. Hohenlohe, Ted F. Cosart, Matthew C. Boyer, Helen H. Neville, Clint C. Muhlfeld, Stephen J. Amish, Kellie Carim, Shawn R. Narum, Winsor H. Lowe, Fred W. Allendorf & Gordon Luikart
Evolutionary and ecological consequences of hybridization between native and invasive species are notoriously complicated because patterns of selection acting on non-native alleles can vary throughout the genome and across environments. Rapid advances in genomics now make it feasible to assess locus-specific and genome-wide patterns of natural selection acting on invasive introgression within and among natural populations occupying diverse environments. We quantified genome-wide patterns of admixture across multiple independent hybrid zones of native westslope cutthroat trout...

Data from: Three-dimensional simulation for fast forward flight of a calliope hummingbird

Jialei Song, Bret W. Tobalske, Donald R. Powers, Tyson L. Hedrick & Haoxiang Luo
We present a computational study of flapping-wing aerodynamics of a calliope hummingbird (Selasphorus calliope) during fast forward flight. Three-dimensional wing kinematics were incorporated into the model by extracting time-dependent wing position from high-speed videos of the bird flying in a wind tunnel at 8.3 m s−1. The advance ratio, i.e. the ratio between flight speed and average wingtip speed, is around one. An immersed-boundary method was used to simulate flow around the wings and bird...

Data from: Linking landscape-scale differences in forage to ungulate nutritional ecology

Kelly M. Proffitt, Mark Hebblewhite, Wibke Peters, Nicole Hupp & Julee Shamhart
Understanding how habitat and nutritional condition affect ungulate populations is necessary for informing management, particularly in areas experiencing carnivore recovery and declining ungulate population trends. Variations in forage species availability, plant phenological stage, and the abundance of forage make it challenging to understand landscape-level effects of nutrition on ungulates. We developed an integrated spatial modeling approach to estimate landscape-level elk (Cervus elaphus) nutritional resources in two adjacent study areas that differed in coarse measures of...

Data from: Camera-based occupancy monitoring at large scales: power to detect trends in grizzly bears across the Canadian Rockies

Robin Steenweg, Mark Hebblewhite & Paul M. Lukacs
Monitoring carnivores is critical for conservation, yet challenging because they are rare and elusive. Few methods exist for monitoring wide-ranging species over large spatial and sufficiently long temporal scales to detect trends. Remote cameras are an emerging technology for monitoring large carnivores around the world because of their low cost, non-invasive methodology, and their ability to capture pictures of species of concern that are difficult to monitor. For species without uniquely identifiable spots, stripes, or...

Data from: Climatic thresholds shape northern high-latitude fire regimes and imply vulnerability to future climate change

Adam M. Young, Philip E. Higuera, Paul A. Duffy & Feng Sheng Hu
Boreal forests and arctic tundra cover 33% of global land area and store an estimated 50% of total soil carbon. Because wildfire is a key driver of terrestrial carbon cycling, increasing fire activity in these ecosystems would likely have global implications. To anticipate potential spatiotemporal variability in fire-regime shifts, we modeled the spatially explicit 30-yr probability of fire occurrence as a function of climate and landscape features (i.e. vegetation and topography) across Alaska. Boosted regression...

Data from: The importance of factors controlling species abundance and distribution varies in native and non-native species.

José L. Hierro, Liana Khetsuriani, Krikor Andonian, Özkan Eren, Diego Villarreal, Grigor Janoian, Kurt O. Reinhart & Ragan M. Callaway
How variation in factors controlling species abundance and distribution between native and non-native ranges compares to that within ranges remains poorly understood. We used a globally distributed ruderal, Centaurea solstitialis (Centaurea), to explore the possibility that the importance of those factors exhibits great variation between and within ranges. To test our hypothesis, we established seed addition experiments with soil disturbance (turnover and control) and biocide (fungicides, insecticide, and control) treatments in two regions within native...

Data from: SNP discovery in candidate adaptive genes using exon capture in a free-ranging alpine ungulate

Gretchen H. Roffler, Stephen J. Amish, Seth Smith, Ted Cosart, Marty Kardos, Michael K. Schwartz & Gordon Luikart
Identification of genes underlying genomic signatures of natural selection is key to understanding adaptation to local conditions. We used targeted resequencing to identify SNP markers in 5,321 candidate adaptive genes associated with known immunological, metabolic, and growth functions in ovids and other ungulates. We selectively targeted 8,161 exons in protein-coding and nearby 5′ and 3′ untranslated regions of chosen candidate genes. Targeted sequences were taken from bighorn sheep (O. canadensis) exon capture data and directly...

Data from: Candidate adaptive genes associated with lineage divergence: identifying SNPs via next-generation targeted resequencing in mule deer (Odocoileus hemionus)

John H. Powell, Stephen J. Amish, Gwilym D. Haynes, Gordon Luikart & Emily K. Latch
Mule deer (Odocoileus hemionus) are an excellent nonmodel species for empirically testing hypotheses in landscape and population genomics due to their large population sizes (low genetic drift), relatively continuous distribution, diversity of occupied habitats and phenotypic variation. Because few genomic resources are currently available for this species, we used exon data from a cattle (Bos taurus) reference genome to direct targeted resequencing of 5935 genes in mule deer. We sequenced approximately 3.75 Mbp at minimum...

Data from: Using camera trapping and hierarchical occupancy modelling to evaluate the spatial ecology of an African mammal community

Lindsey N. Rich, David A. W. Miller, Hugh S. Robinson, J. Weldon McNutt & Marcella J. Kelly
Emerging conservation paradigms have shifted from single to multi-species approaches focused on sustaining biodiversity. Multi-species hierarchical occupancy modelling provides a method for assessing biodiversity while accounting for multiple sources of uncertainty. We analysed camera trapping data with multi-species models using a Bayesian approach to estimate the distributions of a terrestrial mammal community in northern Botswana and evaluate community, group, and species-specific responses to human disturbance and environmental variables. Groupings were based on two life-history traits:...

Data from: Working with what you've got: unattractive males show greater mate-guarding effort in a duetting songbird

Jenélle Dowling & Michael S. Webster
When mates are limited, individuals should allocate resources to mating tactics that maximize fitness. In species with extra-pair paternity (EPP), males can invest in mate guarding, or, alternatively, in seeking EPP. Males should optimize fitness by adjusting investment according to their attractiveness to females, such that attractive males seek EPP, and unattractive males guard mates. This theory has received little empirical testing, leaving our understanding of the evolution of mating tactics incomplete; it is unclear...

Data from: Cats, connectivity and conservation: incorporating datasets and integrating scales for wildlife management

Ross T. Pitman, Julien Fattebert, Samual T. Williams, Kathryn S. Williams, Russell A. Hill, Luke T. B. Hunter, Hugh Robinson, John Power, Lourens Swanepoel, Rob Slotow & Guy A. Balme
Understanding resource selection and quantifying habitat connectivity are fundamental to conservation planning for both land-use and species management plans. However, datasets available to management authorities for resource selection and connectivity analyses are often highly limited and fragmentary. As a result, measuring connectivity is challenging, and often poorly integrated within conservation planning and wildlife management. To exacerbate the challenge, scale-dependent resource use makes inference across scales problematic, resource use is often modelled in areas where the...
