title: Data for: Timing and order of exposure to two echinostome species affect patterns of infection in larval amphibians

description: &lt;p&gt;The study of priority effects with respect to coinfections is still in its infancy. Moreover, existing coinfection studies typically focus on infection outcomes associated with exposure to distinct sets of parasite species, despite that functionally and morphologically similar parasite species commonly coexist in nature. Therefore, it is important to understand how interactions between similar parasites influence infection outcomes. Surveys at seven ponds in northwest Pennsylvania found that multiple species of echinostomes commonly co-occur. Using a larval anuran host (Rana pipiens) and the two most commonly identified echinostome species from our field surveys (Echinostoma trivolvis and Echinoparyphium lineage 3), we examined how species composition and timing of exposure affect patterns of infection. When tadpoles were exposed to both parasites simultaneously, infection loads were higher than when exposed to Echinoparyphium alone but similar to being exposed to Echinostoma alone. When tadpoles were sequentially exposed to the parasite species, tadpoles first exposed to Echinoparyphium had 23% lower infection loads than tadpoles first exposed to Echinostoma. These findings demonstrate that exposure timing and order, even with similar parasites, can influence coinfection outcomes, and emphasize the importance of using molecular methods to identify parasites for ecological studies.&lt;/p&gt;

title: Estimated land cover properties for hydrologic modeling in Arequipa, Peru

description: &lt;p&gt;This dataset contains estimated land cover properties required for the Soil and Water Assessment Tool (SWAT) hydrologic modeling in the Arequipa department of Peru. In a two-step process, first, SWAT equivalent land covers to local land cover types were identified and their properties were used as the base for the database development. Then parameters that control the seasonal growth cycle were modified to better reflect the characteristics of local vegetation. The resulting database and raster land cover map are provided in a format suitable for SWAT model development.&lt;/p&gt;

title: Metabolic Source Isotopic Pair Labeling and Genome-Wide Association Are Complementary Tools for the Identification of Metabolite-Gene Associations in Plants

description: &lt;p&gt;The optimal extraction of information from untargeted metabolomics analyses is a continuing challenge. Here we describe an approach that combines stable isotope labeling, LC-MS, and a computational pipeline to automatically identify metabolites produced from a selected metabolic precursor. We identified the subset of the soluble metabolome generated from phenylalanine in &lt;em&gt;Arabidopsis thaliana&lt;/em&gt;, which we refer to as the phenylalanine-derived metabolome (FDM) In addition to identifying Phe-derived metabolites present in a single wild-type reference accession, the FDM was established in nine enzymatic and regulatory mutants in the phenylpropanoid pathway. To identify genes associated with variation in Phe-derived metabolites in Arabidopsis, MS features collected by untargeted metabolite profiling of an Arabidopsis diversity panel were retrospectively annotated to the FDM and natural genetic variants responsible for differences in accumulation of FDM features were identified by genome-wide association. Large differences in Phe-derived metabolite accumulation and presence/absence variation of abundant metabolites were observed in the nine mutants as well as between accessions from the diversity panel. Many Phe-derived metabolites that accumulated in mutants also accumulated in non-Col-0 accessions and was associated to genes with known or suspected functions in the phenylpropanoid pathway as well as genes with no known functions. Overall, we show that cataloguing a biochemical pathway&rsquo;s products through isotopic labeling across genetic variants can substantially contribute to the identification of metabolites and genes associated with their biosynthesis.&lt;/p&gt;

title: Population-specific brain atlases for early-to-middle adolescent collision-sport athletes

description: &lt;p&gt;This repository present population-specific brain atlases for early-to-middle adolescent (ages 13-19) collision-sport athletes, based on the MRI scans from the longitudinal database of Purdue Neurotrauma Group. The brain atlases were developed in an effort to facilitate multimodal neuroimaging studies, specifically to minimize bias introduced in spatial normalization, improve sensitivity of voxel-wise statistical analysis, and therefore better clarify the mechanisms that lead to traumatic brain injury in adolescent athletes, which is one of our long-term commitments to this vulnerable population. Image processing software including &lt;em&gt;FSL,&lt;/em&gt; &lt;em&gt;ANTs&lt;/em&gt;, and &lt;em&gt;FreeSurfer&lt;/em&gt; were used to create the templates (T1-weighted and DTI) and semantic labels (cortical and white matter parcellations). To scale and speed up the atlas creation, we established a high-throughput high-performance computing workflow which integrated Open Science Grid and Purdue Community Clusters.&lt;/p&gt;

title: A Rainfall-based, Sequential Depression-filling Algorithm and Applications on a Watershed in Northeastern Indiana, USA

description: &lt;p&gt;The landscapes across much of the Midwestern United States are characterized by glacial activity that left water-holding kettles, depressions, and potholes. Until recently, traditional watershed algorithms assumed these depressions to be errors in the elevation data and filled them as a means of correction, when, in reality, many of these features may rarely fill and have the potential to dramatically affect surface flow patterns. These depressions play an important role in hydrology, water management, site planning, and agronomy.&lt;/p&gt;
&lt;p&gt;An optimized sequential depression-filling algorithm (sdfa) was developed which fills these water-holding features sequentially based on their respective retention capacity and contributing area. Outputs reflect the state of connectivity following the application of a user-specified amount of rainfall excess (i.e., in excess of infiltration); depressions that have not been filled will remain as their own hydrologically common subcatchments. A performant algorithm is integral to future delivery and utilization by practitioners both in the office and in the field. The optimal set of subroutines were able to fill all of the depressions in a 239 km&lt;sup&gt;2&lt;/sup&gt; watershed in northeastern Indiana in 42 seconds and 1.5 hours on a consumer desktop computer for digital elevation models (DEMs) at 30-meter and 3-meter resolutions, respectively (O(n&lt;sup&gt;2&lt;/sup&gt;) overall performance).&lt;/p&gt;

title: Dry Matter Intake and Beta-Hydroxybutyrate Response in a GTT in Phase Shifted Dairy Cows

description: &lt;p&gt;Supplemental figures from paper published in Journal of Dairy Science &lt;/p&gt;

&lt;p&gt;Circadian and metabolic systems are interlocked and reciprocally regulated. To determine if the circadian system regulates glucose homeostasis and mammary development, the function of the circadian system was disrupted by exposing cattle to chronic light-dark cycle phase shifts from five wk before expected calving (BEC) to parturition. Multiparous Holstein cows were exposed to 16 h of light and 8 h of dark (CON, n=8) or phase shifting (PS, n=8) the light cycle 6 h every 3 d beginning 35 d BEC. After calving, both treatments were exposed to control lighting. Intravenous glucose tolerance test (IVGTT) was performed at 14 d BEC and 7 DIM by administering 50% dextrose. Blood &beta;-hydroxybutyrate (BHB) was consequently measured over 3 h. Additionally, dry matter intake (DMI) was recorded for all cows between 35 d BEC through 21 DIM. At 14 d BEC and 7 DIM there were no treatment differences in BHB concentrations. Additionally, there was no difference in DMI between the treatments. Thereby indicating that light shifting circadian disruptions do not impact cattle BHB concentrations during an IVGTT or feed intake.&lt;/p&gt;
description: Circadian disruptions in dairy cattle did not affect BHB concentrations in response to an IVGTT at 14 days before expected calving and 7 days in milk. Additionally, there was no effect of disruptions on dry matter intake

title: Seasonal variation in abundance and diversity of eavesdropping frog‐biting midges (Diptera, Corethrellidae) in a neotropical rainforest

description: &lt;p&gt;In the tropics, precipitation patterns result in seasonal fluctuations in the abundance and distribution of plant and animal species. Tropical predators and parasites are therefore faced with seasonal changes in prey and host availability. This study investigates the seasonal interaction among a specialised ectoparasite, eavesdropping frog‐biting midges (Corethrella spp.), and their anuran hosts, examining how the abundance and diversity of the frog‐biting midge community fluctuate between the rainy (host abundant) and dry (host sparse) seasons. Midges were captured in both the rainy and dry seasons using acoustic playbacks of calls from a common frog species that breeds during the rainy season, the t&uacute;ngara frog (Engystomops, Physalaemus, pustulosus). During the dry season t&uacute;ngara frog choruses are absent. To explore seasonal shifts in host preference or changes in the midge community due to host specificity, midges were also captured using playbacks of calls from a frog that breeds during the dry season, the pug‐nosed tree frog (Smilisca sila). While the overall abundance of midges decreased in the dry season, only slight differences in the relative abundance between midge species were found. These results suggest that midge populations can shift between hosts as they become available across seasons, allowing adult populations of frog‐biting midges to persist year‐round. To overcome the challenge of detecting and localising different host species, it is proposed that frog‐biting midges have evolved a generalised acoustic template, allowing them to respond to a broad range of available hosts, regardless of seasonal host composition.&lt;/p&gt;

title: Synchronized mating signals in a communication network: the challenge of avoiding predators while attracting mates

description: &lt;p&gt;Conspicuous mating signals attract mates but also expose signallers to predators and parasites. Signal evolution, therefore, is driven by conflicting selective pressures from multiple receivers, both target and non-target. Synchronization of mating signals, for example, is an evolutionary puzzle, given the assumed high cost of reduced female attraction when signals overlap. Synchronization may be beneficial, however, if overlapping signals reduce attraction of non-target receivers. We investigate how signal synchronization is shaped by the trade-off between natural and sexual selection in two anuran species: pug-nosed tree frogs (&lt;i&gt;Smilisca sila&lt;/i&gt;), in which males produce mating calls in near-perfect synchrony, and t&uacute;ngara frogs (&lt;i&gt;Engystomops pustulosus&lt;/i&gt;), in which males alternate their calls. To examine the trade-off imposed by signal synchronization, we conducted field and laboratory playback experiments on eavesdropping enemies (bats and midges) and target receivers (female frogs). Our results suggest that, while synchronization can be a general strategy for signallers to reduce their exposure to eavesdroppers, relaxed selection by females for unsynchronized calls is key to the evolution and maintenance of signal synchrony. This study highlights the role of relaxed selection in our understanding of the origin of mating signals and displays.&lt;/p&gt;
description: We investigate how signal synchronization is shaped by natural and sexual selection in two frog species. Our results show that synchronization reduces exposure to eavesdroppers and relaxed selection by females is likely important.

title: Prey exploits the auditory illusions of eavesdropping predators

description: &lt;p&gt;Mating signals have evolved to attract target receivers, even to the point of exploiting receivers through perceptual manipulation. Signals, however, can also expose signalers to nontarget receivers, including predators and parasites, and thus have also evolved to decrease enemy attraction. Here we show that male tree frogs (&lt;i&gt;Smilisca sila&lt;/i&gt;) reduce their attractiveness to eavesdropping enemies (bats and midges) by overlapping their calls at near-perfect synchrony with the calls of neighboring conspecifics. By producing calls that closely follow those of other males, synchronizing &lt;i&gt;S. sila&lt;/i&gt; take advantage of an auditory illusion where enemies are more attracted to the leading call. Female &lt;i&gt;S. sila&lt;/i&gt;, however, are less susceptible to this illusion. Thus, synchronization among signaling males can result in acoustic crypsis from predators without affecting female attraction. Given the widespread use of conspicuous mating signals and eavesdropping enemies, perceptual exploitation of eavesdroppers is likely a common driver of signal evolution.&lt;/p&gt;
