This volume of Transforming Institutions follows from and builds on its predecessor of five years ago (Weaver et al., 2015) with a mix of case studies, models, and analyses. The authors and editors provide key perspectives for advancing change initiatives in higher education and STEM education. The Transforming Institutions conferences and book series began with the first convening in 2011 at Purdue University, organized by the Discovery Learning Research Center (DLRC), and continues with the...
Habitat transitions alter the adaptive landscape and shape phenotypic evolution in needlefishes (Belonidae)Matthew Kolmann, Michael D. Burns, Justin Y. K. Ng, Nathan R. Lovjoy & Devin D. Bloom
Habitat occupancy can have a profound influence on macroevolutionary dynamics, and a switch in major habitat type may alter the evolutionary trajectory of a lineage. In this study we investigate how evolutionary transitions between marine and freshwater habitats affect macroevolutionary adaptive landscapes, using needlefishes (Belonidae) as a model system. We examined the evolution of body shape and size in marine and freshwater needlefishes and tested for phenotypic change in response to transitions between habitats. Using...
In the first 20 orbits of the Juno spacecraft around Jupiter, we have identified a variety of wave-like features in images made by its public-outreach camera, JunoCam. Because of Juno’s unprecedented and repeated proximity to Jupiter’s cloud tops during its close approaches, JunoCam has detected more wave structures than any previous surveys. Most of the waves appear in long wave packets, oriented east-west and populated by narrow wave crests. Spacing between crests were measured as...
Data from: Patterns of parasite community dissimilarity: the significant role of land use and lack of distance-decay in a bat—helminth systemElizabeth M. Warburton, Steven L. Kohler & Maarten J. Vonhof
Increasing community dissimilarity across geographic distance has been described for a wide variety of organisms and understanding its underlying causes is key to understanding mechanisms driving patterns of biodiversity. Both niche-based and neutral processes may produce a distance decay relationship; however, disentangling their relative influence requires simultaneous examination of multiple potential drivers. Parasites represent a unique opportunity in which to study distance decay because community dissimilarity may depend on environmental requirements and dispersal capability of...
Data from: Host association influences variation at salivary protein genes in the bat ectoparasite Cimex adjunctusBenoit Talbot, Maarten J. Vonhof, Hugh G. Broders, Brock Fenton & Nusha Keyghobadi
Parasite-host relationships create strong selection pressures that can lead to adaptation and increasing specialization of parasites to their hosts. Even in relatively loose host-parasite relationships, such as between generalist ectoparasites and their hosts, we may observe some degree of specialization of parasite populations to one of the multiple potential hosts. Salivary proteins are used by blood-feeding ectoparasites to prevent hemostasis in the host and maximize energy intake. We investigated the influence of association with specific...
Overview This directory was developed to provide discovery information for anyone looking for publicly accessible repositories that house geological materials in the U.S. and Canada. In addition, this resource is intended to be a tool to facilitate a community of practice. The need for the directory was identified during planning for and follow-up from a drill core repository webinar series in Spring 2020 for public repository curators and staff in the U.S. and Canada hosted...
Data from: Genetic structure of little brown bats (Myotis lucifugus) corresponds with spread of white-nose syndrome among hibernaculaCassandra M. Miller-Butterworth, Maarten J. Vonhof, Joel Rosenstern, Gregory G. Turner & Amy L. Russell
Until recently, the little brown bat (Myotis lucifugus) was one of the most common bat species in North America. However, this species currently faces a significant threat from the emerging fungal disease white-nose syndrome (WNS). The aims of this study were to examine the population genetic structure of M. lucifugus hibernating colonies in Pennsylvania (PA) and West Virginia (WV), and to determine whether that population structure may have influenced the pattern of spread of WNS....
Data from: A century of intermittent eco-evolutionary feedbacks resulted in novel trait combinations in invasive great lakes Alewives (Alosa pseudoharengus)Shelby Smith, Eric Palkovacs, Brian Weidel, David Bunnell, Andrew Jones & Devin Bloom
Species introductions provide opportunities to quantify rates and patterns of evolutionary change in response to novel environments. Alewives (Alosa pseudoharengus) are native to the East Coast of North America where they ascend coastal rivers to spawn in lakes, and then return to the ocean. Some populations have become landlocked within the last 350 years and diverged phenotypically from their ancestral marine population. More recently alewives were introduced to the Laurentian Great Lakes (~150 years ago),...
Animals select and use habitats based on environmental features relevant to their ecology and behavior. For animals that use acoustic communication, the sound environment itself may be a critical feature, yet acoustic characteristics are not commonly measured when describing habitats and as a result, how habitats vary acoustically over space and time is poorly known. Such considerations are timely, given worldwide increases in anthropogenic noise combined with rapidly accumulating evidence that noise hampers the ability...
Data from: When genes move farther than offspring: gene flow by male gamete dispersal in the highly philopatric bat species Thyroptera tricolorMichael R. Buchalski, Gloriana Chaverri & Maarten J. Vonhof
For species characterized by philopatry of both sexes, mate selection represents an important behavior for inbreeding avoidance, yet the implications for gene flow are rarely quantified. Here we present evidence of male gamete mediated gene flow resulting from extra-group mating in Spix’s disk-winged bat, Thyroptera tricolor, a species which demonstrates all-offspring philopatry. We used microsatellite and capture-recapture data to characterize social group structure and the distribution of mated pairs at two sites in southwestern Costa...
Selection against migrants is key to maintaining genetic differences between populations linked by dispersal. However, migrants may mitigate fitness costs by proactively choosing among available habitats, or by phenotypic plasticity. We previously reported that a reciprocal transplant of lake and stream stickleback (Gasterosteus aculeatus) found little support for divergent selection. Here, we revisit that experiment to test whether phenotypic plasticity in gene expression may have helped migrants adjust to unfamiliar habitats. We measured gene expression...
Data from: Social context and noise affect within and between-male song adjustments in a common passerineErin Grabarczyk, Maarten Vonhof & Sharon Gill
Across populations, animals that inhabit areas with high anthropogenic noise produce vocalizations that differ from those inhabiting less noisy environments. Such patterns may be due to individuals rapidly adjusting their songs in response to changing noise, but individual variation is seldom explored. We tested the hypothesis that male house wrens (Troglodytes aedon) immediately adjust their songs according to changing noise, and that social context further modifies responses. We recorded songs, quantified noise, and defined social...
