In contrast to the majority of primates, which exhibit dedicated diurnality or nocturnality, all species of Eulemur are cathemeral. Color vision, in particular, is strongly affected by the spectral composition and intensity of ambient light, and the impact of activity period on the evolution of primate color vision is actively debated. We studied three groups of wild brown lemurs (Eulemur fulvus) in Ankarafantsika National Park, Madagascar over a one-year span. We also used non-invasive fecal...

Data from: Mind the gap: genetic manipulation of basicranial growth within synchondroses modulates calvarial and facial shape in mice through epigenetic interactions

Trish E. Parsons, Charlene M. Downey, Frank R. Jirik, Benedikt Hallgrimsson & Heather A. Jamniczky
Phenotypic integration patterns in the mammalian skull have long been a focus of intense interest as a result of their suspected influence on the trajectory of hominid evolution. Here we test the hypothesis that perturbation of cartilage growth, which directly affects only the chondrocranium during development, will produce coordinated shape changes in the adult calvarium and face regardless of mechanism. Using two murine models of cartilage undergrowth that target two very different mechanisms, we show...

Data from: Targeted capture and resequencing of 1040 genes reveal environmentally driven functional variation in gray wolves

Rena M. Schweizer, Jacqueline Robinson, Ryan Harrigan, Pedro Silva, Marco Galaverni, Marco Musiani, Richard E. Green, John Novembre & Robert K. Wayne
In an era of ever-increasing amounts of whole genome sequence data for individuals and populations, the utility of traditional single nucleotide polymorphisms (SNPs) array-based genome scans is uncertain. We previously performed a SNP array-based genome scan to identify candidate genes under selection in six distinct gray wolf (Canis lupus) ecotypes. Using this information, we designed a targeted capture array for 1040 genes, including all exons and flanking regions, as well as 5000 1 kb non-genic...

Data from: Phylogeography of the prickly sculpin (Cottus asper) in north-western North America reveals parallel phenotypic evolution across multiple coastal–inland colonizations

Stefan Dennenmoser, Arne W. Nolte, Steven M. Vamosi & Sean M. Rogers
Aim: Glacial cycles during the Pleistocene may have frequently contributed to parallel evolution of phenotypes across independently evolving genetic lineages associated with separate glacial refugia. Previous studies based on morphology suggested that the prickly sculpin (Cottus asper) survived the Last Glacial Maximum (LGM) in southern coastal and inland refugia, favouring allopatric divergence between coastal and inland prickling phenotypes, which vary in the degree to which spine-like scales cover the body of the fish. Herein, we...

Data from: Genetic subdivision and candidate genes under selection in North American gray wolves

Rena M. Schweizer, Bridgett M. VonHoldt, Ryan Harrigan, James C. Knowles, Marco Musiani, David Coltman, John Novembre & Robert K. Wayne
Previous genetic studies of the highly mobile gray wolf (Canis lupus) found population structure that coincides with habitat and phenotype differences. We hypothesized that these ecologically distinct populations (ecotypes) should exhibit signatures of selection in genes related to morphology, coat color, and metabolism. To test these predictions, we quantified population structure related to habitat using a genotyping array to assess variation in 42,036 SNPs in 111 North American gray wolves. Using these SNP data and...

Data from: Transcriptome analysis of 20 taxonomically related benzylisoquinoline alkaloid-producing plants

Jillian M. Hagel, Jeremy S. Morris, Eun-Jeong Lee, Isabel Desgagné-Penix, Crystal D. Bross, Limei Chang, Xue Chen, Scott C. Farrow, Ye Zhang, Jung Soh, Christoph W. Sensen & Peter J. Facchini
Background: Benzylisoquinoline alkaloids (BIAs) represent a diverse class of plant specialized metabolites sharing a common biosynthetic origin beginning with tyrosine. Many BIAs have potent pharmacological activities, and plants accumulating them boast long histories of use in traditional medicine and cultural practices. The decades-long focus on a select number of plant species as model systems has allowed near or full elucidation of major BIA pathways, including those of morphine, sanguinarine and berberine. However, this focus has...

Data from: Dioecy does not consistently accelerate or slow lineage diversification across multiple genera of angiosperms

Niv Sabath, Emma E. Goldberg, Lior Glick, Moshe Einhorn, Tia-Lynn Ashman, Ray Ming, Sarah P. Otto, Jana Vamosi, Itay Mayrose & Jana C. Vamosi
Dioecy, the sexual system in which male and female organs are found in separate individuals, allows greater specialization for sex-specific functions and can be advantageous under various ecological and environmental conditions. However, dioecy is rare among flowering plants. Previous studies identified contradictory trends regarding the relative diversification rates of dioecious lineages vs their nondioecious counterparts, depending on the methods and data used. We gathered detailed species-level data for dozens of genera that contain both dioecious...

Data from: The extended Price equation quantifies species selection on mammalian body size across the Palaeocene/Eocene Thermal Maximum

Brian D. Rankin, Jeremy W. Fox, Christian R. Barrón-Ortiz, Amy E. Chew, Patricia A. Holroyd, Joshua A. Ludtke, Xingkai Yang & Jessica M. Theodor
Species selection, covariation of species’ traits with their net diversification rates, is an important component of macroevolution. Most studies have relied on indirect evidence for its operation and have not quantified its strength relative to other macroevolutionary forces. We use an extension of the Price equation to quantify the mechanisms of body size macroevolution in mammals from the latest Palaeocene and earliest Eocene of the Bighorn and Clarks Fork Basins of Wyoming. Dwarfing of mammalian...

Data from: Toward the genetic origins of a potentially non-native population of threespine stickleback (Gasterosteus aculeatus) in Alberta

Andrew M. Rezansoff, Erika Crispo, Christopher Blair, Edward Cruz, Jun Kitano, Steven M. Vamosi & Sean M. Rogers
Disentangling the origin of putatively introduced/invasive species is of increasing priority in conservation biology. The presence of a previously undocumented species may be due to an undetected recent population or range expansion associated with environmental change, or due to an introduction by humans. We used molecular tools to address the origin of a population of threespine stickleback (Gasterosteus aculeatus) first identified in central Alberta, Canada in 1980 from a single lake. We characterized this inland,...

Data from: Ectoparasites and fitness of female Columbian ground squirrels

Shirley Raveh, Peter Neuhaus & F. Stephen Dobson
Parasites play an important role in the evolution of host traits via natural selection, coevolution and sexually selected ornaments used in mate choice. These evolutionary scenarios assume fitness costs for hosts. To test this assumption, we conducted an ectoparasite removal experiment in free-living Columbian ground squirrels (Urocittelus columbianus) in four populations over three years. Adult females were randomly chosen to be either experimentally treated with anti-parasite treatments (spot-on solution and flea powder, N = 61)...

Data from: Climate change impacts on bumblebees converge across continents

Jeremy T. Kerr, Alana Pindar, Paul Galpern, Laurence Packer, Stuart M. Roberts, Pierre Rasmont, Oliver Schweiger, Sheila R. Colla, Leif L. Richardson, David L. Wagner, Lawrence F. Gall, Derek S. Sikes & Alberto Pantoja
For many species, geographical ranges are expanding toward the poles in response to climate change, while remaining stable along range edges nearest the equator. Using long-term observations across Europe and North America over 110 years, we tested for climate change–related range shifts in bumblebee species across the full extents of their latitudinal and thermal limits and movements along elevation gradients. We found cross-continentally consistent trends in failures to track warming through time at species’ northern...

Data from: Fine-scale ecological and genetic population structure of two whitefish (Coregoninae) species in the vicinity of industrial thermal emissions

Thermal pollution from industrial processes can have negative impacts on the spawning and development of cold-water fish. Point sources of thermal effluent may need to be managed to avoid affecting discrete populations. Correspondingly, we examined fine-scale ecological and genetic population structure of two whitefish species (Coregonus clupeaformis and Prosopium cylindraceum) on Lake Huron, Canada, in the immediate vicinity of thermal effluent from nuclear power generation. Niche metrics using δ13C and δ15N stable isotopes showed high...

Data from: Impacts of degraded DNA on restriction enzyme associated DNA sequencing (RADSeq)

Carly F. Graham, Travis C. Glenn, Andrew G. McArthur, Douglas R. Boreham, Troy Kieran, Stacey Lance, Richard G. Manzon, Jessica A. Martino, Todd Pierson, Sean M. Rogers, Joanna Y. Wilson & Christopher M. Somers
Degraded DNA from suboptimal field sampling is common in molecular ecology. However, its impact on techniques that use restriction site associated next-generation DNA sequencing (RADSeq, GBS) is unknown. We experimentally examined the effects of in situDNA degradation on data generation for a modified double-digest RADSeq approach (3RAD). We generated libraries using genomic DNA serially extracted from the muscle tissue of 8 individual lake whitefish (Coregonus clupeaformis) following 0-, 12-, 48- and 96-h incubation at room...

Data from: Feather corticosterone reveals stress associated with dietary changes in a breeding seabird

Alexis P. Will, Yutaka Watanuki, Dale M. Kikuchi, Nobuhiko Sato, Motohiro Ito, Matt Callahan, Katherine Wynne-Edwards, Scott Hatch, Kyle H. Elliott, Leslie Slater, Akinori Takahashi, Alexander S. Kitaysky, Kyle Elliott, Alexis Will & Alexander Kitaysky
Changes in climate and anthropogenic pressures might affect the composition and abundance of forage fish in the world's oceans. The junk-food hypothesis posits that dietary shifts that affect the quality (e.g., energy content) of food available to marine predators may impact their physiological state and consequently affect their fitness. Previously, we experimentally validated that deposition of the adrenocortical hormone, corticosterone, in feathers is a sensitive measure of nutritional stress in seabirds. Here, we use this...

Data from: Assessing individual patterns of Echinococcus multilocularis infection in urban coyotes: non-invasive genetic sampling as epidemiological tool

Stefano Liccioli, Sean Rogers, Claudia Greco, Susan J. Kutz, Florence Chan, Kathreen E. Ruckstuhl & Alessandro Massolo
1. In epidemiological studies of wildlife parasites, faecal genotyping has been introduced to prevent bias in estimates of parasite prevalence from faecal samples collected in the field. Such an approach could be particularly relevant in the study of Echinococcus multilocularis transmission in urban settings, where estimates of prevalence and patterns of infection in wild canid hosts are key parameters used in zoonotic risk assessment and management. However, no previous study has evaluated the reliability of...
