North American Hard Yellow Liver Disease: An Old Problem Readdressed

Bryan L. Stegelmeier, Meredyth Jones, Christopher P. Womack, T. Zane Davis & Dale R. Gardner
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,...

Data from: Ionome and elemental transport kinetics shaped by parallel evolution in threespine stickleback

Seth M. Rudman, Jared M. Goos, Joseph B. Burant, Kevin V. Brix, Taylor C. Gibbons, Colin J. Brauner & Punidan D. Jeyasingh
Evidence that organisms evolve rapidly enough to alter ecological dynamics necessitates investigation of the reciprocal links between ecology and evolution. Data that link genotype to phenotype to ecology are needed to understand both the process and ecological consequences of rapid evolution. Here we quantified the suite of elements in individuals (i.e., ionome) and the fluxes of key nutrients across populations of threespine stickleback. We find that allelic variation associated with freshwater adaptation that controls bony...

Differential Proteomic Expression of Equine Cardiac and Lamellar Tissue During Insulin-Induced Laminitis

Allison Campolo, Matthew Frantz, Melody De Laat, Steven Hartson, Martin Furr & Veronique Lacombe
Endocrinopathic laminitis is pathologically similar to the multi-organ dysfunction and peripheral neuropathy found in human patients with metabolic syndrome. Similarly, endocrinopathic laminitis has been shown to partially result from vascular dysfunction. However, despite extensive research, the pathogenesis of this disease is not well elucidated and laminitis remains without an effective treatment. Here, we sought to identify novel proteins and pathways underlying the development of equine endocrinopathic laminitis. Healthy Standardbred horses (n=4/group) were either given an...

Data from: Disrupting information alters the response to a signal trait in both sexes of Nicrophorus beetles

Jillian D. Wormington & Barney Luttbeg
Effective signals transfer information in a way that enhances the fitness of the sender. Signal traits are often sexually dimorphic. However, in some species males and females display similar signals, and these mutual signals are less often studied. Competition for resources occurs in both males and females, and mate choice is likely to occur whenever mates vary in quality and reproductive investment is high. Nicrophorus burying beetles compete intrasexually over the carrion resources on which...

Data from: An empirical assessment of a single family-wide hybrid capture locus set at multiple evolutionary timescales in Asteraceae

Katy E Jones, Tomáš Fér, Roswitha E Schmickl, Rebecca B Dikow, Vicki A Funk, Sonia Herrando-Moraira, Norbert Kilian, Carolina M Siniscalchi, Alfonso Susanna, Marek Slovák, Ramhari Thapa, Linda E Watson & Jennifer R Mandel
Premise of the study: Hybrid capture with high-throughput sequencing (Hyb-Seq) is a powerful tool for evolutionary studies. The applicability of an Asteraceae family-specific Hyb-Seq method and the outcomes of different phylogenetic analyses are assessed. Methods: Hyb-Seq data from 112 Asteraceae samples were organized into groups at different taxonomic levels (tribe, genus, and species). For each group, datasets of non-paralogous loci were built and proportions of parsimony informative characters estimated. The impacts of the analyzing alternative...

Data from: Safety cues can give prey more valuable information than danger cues

Barney Luttbeg, Maud C O Ferrari, Daniel T Blumstein & Douglas P Chivers
The ability of prey to assess predation risk is fundamental to their success. It is routinely assumed predator cues do not vary in reliability across levels of predation risk. We propose that cues can differ in how precisely they indicate different levels of predation risk. What we call danger cues precisely indicate high risk levels, while safety cues precisely indicate low risk levels. Using optimality modeling, we find that prey fitness is increased when prey...

Building façade-level correlates of bird-window collisions in a small urban area

Scott R. Loss, Corey S. Riding & Timothy J. O'Connell
Urbanization increasingly exposes birds to multiple sources of direct anthropogenic mortality. Collisions with buildings, and windows in particular, are a top bird mortality source, annually causing 365-988 million fatalities in the United States. Correlates of window collision rates have been studied at the scale of entire buildings and in relation to the surrounding landscape, and most studies have only assessed correlates for all birds combined without considering season- and species-specific risk factors. In Stillwater, Oklahoma,...

Spatial sampling bias and model complexity in stream-based species distribution models: a case study of Paddlefish (Polyodon spathula) in the Arkansas River basin, U.S.A.

Andrew Taylor, Thomas Hafen, Colt Holley, Alin González & James Long
Leveraging existing presence records and geospatial datasets, species distribution modeling has been widely applied to informing species conservation and restoration efforts. Maxent is one of the most popular modeling algorithms, yet recent research has demonstrated Maxent models are vulnerable to prediction errors related to spatial sampling bias and model complexity. Despite elevated rates of biodiversity imperilment in stream systems, the application of Maxent models to stream networks has lagged, as has the availability of tools...

Data from: Integrated metabolic strategy: a framework for predicting the evolution of carbon-water tradeoffs within plant clades

Ellie M. Goud, Jed P. Sparks, Mark Fishbein & Anurag A. Agrawal
1. The fundamental tradeoff between carbon gain and water loss has long been predicted as an evolutionary driver of plant strategies across environments. Nonetheless, challenges in measuring carbon gain and water loss in ways that integrate over leaf lifetime have limited our understanding of the variation in and mechanistic bases of this tradeoff. Furthermore, the microevolution of plant traits within species versus the macroevolution of strategies among closely related species may not be same, and...
