Data from: Explosion-generated infrasound recorded on ground and airborne microbarometers at regional distances

Eliot F. Young, Daniel C. Bowman, Jonathan M. Lees, Viliam Klein, Steven J. Arrowsmith & Courtney Ballard
Recent work in deploying infrasound (low frequency sound) sensors on aerostats and free flying balloons has shown them to be viable alternatives to ground stations. However, no study to date has compared the performance of surface and free floating infrasound microbarometers with respect to acoustic events at regional (100s of kilometers) range. The prospect of enhanced detection of aerial explosions at similar ranges, such as those from bolides, has not been investigated either. We examined...

Data from: Genomic differentiation during speciation-with-gene-flow: comparing geographic and host-related variation in divergent life history adaptation in Rhagoletis pomonella

A major goal of evolutionary biology is to understand how variation within populations gets partitioned into differences between reproductively isolated species. Here, we examine the degree to which diapause life history timing, a critical adaptation promoting population divergence, explains geographic and host-related genetic variation in ancestral hawthorn and recently derived apple-infesting races of Rhagoletis pomonella. Our strategy involved combining experiments on two different aspects of diapause (initial diapause intensity and adult eclosion time) with a...

Data from: Information-theoretic analysis of realistic odor plumes: what cues are useful for determining location?

Sebastian D. Boie, Erin G. Connor, Margaret McHugh, Katherine I. Nagel, G. Bard Ermentrout, John P. Crimaldi & Jonathan D. Victor
Many species rely on olfaction to navigate towards food sources or mates. Olfactory navigation is a challenging task since odor environments are typically turbulent. While time-averaged odor concentration varies smoothly with the distance to the source, instaneous concentrations are intermittent and obtaining stable averages takes longer than the typical intervals between animals’ navigation decisions. How to effectively sample from the odor distribution to determine sampling location is the focus on this article. To investigate which...

Data from: FEATHER: automated analysis of force spectroscopy unbinding and unfolding data via a Bayesian algorithm

Patrick R. Heenan & Thomas T. Perkins
Single-molecule force spectroscopy (SMFS) provides a powerful tool to explore the dynamics and energetics of individual proteins, protein-ligand interactions, and nucleic acid structures. In the canonical assay, a force probe is retracted at constant velocity to induce a mechanical unfolding/unbinding event. Next, two energy landscape parameters, the zero-force dissociation rate constant (ko) and the distance to the transition state (Δx‡), are deduced by analyzing the most probable rupture force as a function of the loading...

Data from: Disease and climate effects on individuals drive post-reintroduction population dynamics of an endangered amphibian

Maxwell B. Joseph & Roland A. Knapp
The emergence of novel pathogens often has dramatic negative effects on previously unexposed host populations. Subsequent disease can drive populations and even species to extinction. After establishment in populations, pathogens can continue to affect host dynamics, influencing the success or failure of species recovery efforts. However, quantifying the effect of pathogens on host populations in the wild is challenging because individual hosts and their pathogens are difficult to observe. Here we use long-term mark-recapture data...

Data from: Experimental habitat fragmentation disrupts nematode infections in Australian skinks

Julian Resasco, Matthew E. Bitters, Saul A. Cunningham, Hugh I. Jones, Valerie J. McKenzie & Kendi F. Davies
Habitat conversion and fragmentation threaten biodiversity and disrupt species interactions. While parasites are recognized as ecologically important, the impacts of fragmentation on parasitism are poorly understood relative to other species interactions. This lack of understanding is in part due to confounding landscape factors that accompany fragmentation. Fragmentation experiments provide the opportunity to fill this knowledge gap by mechanistically testing how fragmentation affects parasitism while controlling landscape factors. In a large-scale, long-term experiment, we asked how...

Data from: Multiple mechanisms confer stability to isolated populations of a rare endemic plant

Reilly R. Dibner, Megan L. Peterson, Allison M. Louthan & Daniel F. Doak
The persistence of small populations remains a puzzle for ecology and conservation. Especially interesting is how naturally small, isolated populations are able to persist in the face of multiple environmental forces that create fluctuating conditions and should, theory predicts, lead to high probabilities of extirpation. We used a combination of long term census data and a five-year demographic study of a naturally rare, endemic plant, Yermo xanthocephalus, to evaluate the importance of several possible mechanisms...
