Data from: Influence of drift and admixture on population structure of American black bears (Ursus americanus) in the Central Interior Highlands, U.S.A. 50 years after translocationEmily E. Puckett, Thea V. Kristensen, Clay M. Wilton, Sara B. Lyda, Karen V. Noyce, Paula M. Holahan, , Jeff Beringer, Jerrold L. Belant, , Lori S. Eggert & David M. Leslie
Bottlenecks, founder events, and genetic drift often result in decreased genetic diversity and increased population differentiation. These events may follow abundance declines due to natural or anthropogenic perturbations, where translocations may be an effective conservation strategy to increase population size. American black bears (Ursus americanus) were nearly extirpated from the Central Interior Highlands, USA by 1920. In an effort to restore bears, 254 individuals were translocated from Minnesota, USA and Manitoba, Canada, into the Ouachita...
Grasslands world-wide provide a host of ecosystem services. In particular, these grasslands serve as biodiversity repositories for a myriad of imperilled animal species. One such group is grassland birds, which have experienced significant declines, predominantly caused by extensive loss and degradation of native grasslands. Rangeland management that promotes increasing and sustaining livestock production through reducing the inherent, disturbance-driven variability that historically occurred in grasslands is considered a major contributing factor to these declines. An alternative...
Data from: Immunoglobulin detection in wild birds: effectiveness of three secondary anti-avian IgY antibodies in direct ELISAs in 41 avian speciesCarol A. Fassbinder-Orth, Travis E. Wilcoxen, Tiffany Tran, Raoul K. Boughton, Jeanne M. Fair, Erik K. Hofmeister, Jennifer L. Grindstaff & Jen C. Owen
1.Immunological reagents for wild, non-model species are limited or often non-existent for many species. 2. In this study, we compare the reactivity of a new anti-passerine IgY secondary antibody with existing secondary antibodies developed for use with birds. Samples from 41 species from the following six avian orders were analysed: Anseriformes (1 family, 1 species), Columbiformes (1 family, 2 species), Galliformes (1 family, 1 species), Passeriformes (16 families, 34 species), Piciformes (1 family, 2 species)...
Plants form belowground associations with mycorrhizal fungi in one of the most common symbioses on Earth. However, few large-scale generalizations exist for the structure and function of mycorrhizal symbioses, as the nature of this relationship varies from mutualistic to parasitic and is largely context-dependent. We announce the public release of MycoDB, a database of 4,010 studies (from 438 unique publications) to aid in multi-factor meta-analyses elucidating the ecological and evolutionary context in which mycorrhizal fungi...
Data from: Invasion facilitates hybridization with introgression in the Rattus rattus species complexJustin B. Lack, Daniel U. Greene, Chris John Conroy, Meredith J. Hamilton, Janet K. Braun, Michael A. Mares & Ronald A. Van Den Bussche
Biological invasions result in novel species interactions, which can have significant evolutionary impacts on both native and invading taxa. One evolutionary concern with invasions is hybridization among lineages that were previously isolated, but make secondary contact in their invaded range(s). Black rats, consisting of several morphologically very similar but genetically distinct taxa that collectively have invaded six continents, are arguably the most successful mammalian invaders on the planet. We used mitochondrial cytochrome b sequences, two...
Data from: Evolution in extreme environments: replicated phenotypic differentiation in livebearing fish inhabiting sulfidic springsMichael Tobler, Maura Palacios, Lauren J Chapman, Igor Mitrofanov, David Bierbach, Martin Plath, Lenin Arias-Rodriguez, Francisco J García De León & Mariana Mateos
We investigated replicated ecological speciation in the livebearing fishes Poecilia mexicana and P. sulphuraria (Poeciliidae), which inhabit freshwater habitats and have also colonized multiple sulfidic springs in southern Mexico. These springs exhibit extreme hypoxia and high concentrations of hydrogen sulfide, which is lethal to most metazoans. We used phylogenetic analyses to test whether springs were independently colonized, performed phenotypic assessments of body and gill morphology variation to identify convergent patterns of trait differentiation, and conducted...
Data from: Mismatch between dietary requirements for lipid by a predator and availability of lipid in preyWill D. Wiggins & Shawn M. Wilder
Growth is an important factor in predicting an organism's overall success as an adult. Understanding how abiotic and biotic factors influence body size is key to predicting how environmental changes will impact organisms and predicting optimal behaviors under varying conditions. Food items can vary widely in nutrient content and this variation can affect growth. We tested how the quantity and macronutrient content of live prey affected the growth of juvenile jumping spiders, Phiddipus audax, using...
Data from: Asymmetric energetic costs in reciprocal-cross hybrids between carnivorous mice (Onychomys)J. Ryan Shipley, Polly Campbell, Jeremy B. Searle & Bret Pasch
Aerobic respiration is a fundamental physiological trait dependent on coordinated interactions between gene products of the mitochondrial and nuclear genomes. Mitonuclear mismatch in interspecific hybrids may contribute to reproductive isolation by inducing reduced viability (or even complete inviability) due to increased metabolic costs. However, few studies have tested for effects of mitonuclear mismatch on respiration at the whole organism level. We explored how hybridization affects metabolic rates in closely related species of grasshopper mice (genus...

Hard yellow liver disease or fatty cirrhosis periodically affects cattle, sheep, goats, pronghorn antelope (Antilocapra americana) and whitetail deer (Odocoileus virginianus texanus) within several Texas counties in the United States. Clinically it presents as chronic liver disease with progressive hepatic necrosis and fibrosis, icterus and liver failure. The damaged livers are yellow and many have multiple firm, often gritty foci that are scattered throughout all lobes. Early investigations included feeding studies using potential toxic plants,...
Territorial animals often learn to distinguish their neighbors from unfamiliar conspecifics. This cognitive ability facilitates the dear enemy effect, where individuals respond less aggressively to neighbors than to other individuals, and is hypothesized to be adaptive by reducing unnecessary aggressive interactions with individuals that are not a threat to territory ownership. A key prediction of this hypothesis, that individuals with better ability to learn to recognize neighbors should have higher fitness, has never been tested....
Speed-accuracy tradeoffs – being fast at the risk of being wrong – are fundamental to many decisions and natural selection is expected to resolve these tradeoffs according to the costs and benefits of behavior. We here test the prediction that females and males should integrate information from courtship signals differently because they experience different payoffs along the speed-accuracy continuum. We fitted a neural model of decision making (a drift-diffusion model of integration to threshold) to...
Conventional wisdom holds that carefully designed exterior louver systems tuned to a building’s earth latitude and its glass wall’s compass orientations do a better job of regulating sunlight than interior louver systems due to the intuition-friendly observation that exterior systems reflect or shade the sunlight before it ever enters the building. A multi-criteria, multi-variable analysis performed on a 3600 SF multipurpose space came to different conclusions. The results showed that when accounting for such design...
This study reviews whether check-in/check-out intervention is effective at increasing on-task behavior among attention problem students in the high-school. Also, this study examines whether there is an effectiveness difference between utilizing and not utilizing CICO intervention among the attention problem students.
Here we apply the principles of Hamilton's rule (rB>C) to explore the circumstances under which individuals decide to share with/help others at some cost to oneself. Specifically, we explore helping intentions.
Data for: PickMe: sample selection for species tree reconstruction using coalescent weighted quartetsJoseph Rusinko, Yu Cai, Allison Doherty, Katherine Thompson, Julien Boutte, Mark Fishbein & Shannon Straub
After collecting large data sets of many genes for many species for phylogenomics studies, researchers may make ad hoc decisions about which genes or samples to include in a species tree reconstruction analysis based on various parameters, including the amount of missing data. Optimally, sampling would be maximized, but it can be difficult for empiricists to determine where to draw the line for sample inclusion when data sets are incomplete. Under the multispecies coalescent model,...
