title: Data from: Snap-jaw morphology is specialized for high-speed power amplification in the Dracula ant, Mystrium camillae

description: What is the limit of animal speed and what mechanisms produce the fastest
 movements? More than natural history trivia, the answer provides key
 insight into the form-function relationship of musculoskeletal movement
 and can determine the outcome of predator-prey interactions. The fastest
 known animal movements belong to arthropods, including trap-jaw ants,
 mantis shrimp, and froghoppers, that have incorporated latches and springs
 into their appendage systems to overcome the limits of muscle power. In
 contrast to these examples of power amplification, where separate
 structures act as latch and spring to accelerate an appendage, some
 animals use a “snap-jaw” mechanism that incorporates the latch and spring
 on the accelerating appendage itself. We examined the kinematics and
 functional morphology of the Dracula ant, Mystrium camillae, who use a
 snap-jaw mechanism to quickly slide their mandibles across each other
 similar to a finger snap. Kinematic analysis of high-speed video revealed
 that snap-jaw ant mandibles complete their strike in as little as 23 μsec
 and reaching peak velocities of 90 m s-1, making them the fastest known
 animal appendage. Finite element analysis demonstrated that snap-jaw
 mandibles were less stiff than biting non-power-amplified mandibles,
 consistent with their use as a flexible spring. These results extend our
 understanding of animal speed and demonstrate how small changes in
 morphology can result in dramatic differences in performance.

title: Data from: Genetic architecture and genomic patterns of gene flow between hybridizing species of Picea

description: Hybrid zones provide an opportunity to study the effects of selection and
 gene flow in natural settings. We employed nuclear microsatellites (single
 sequence repeat (SSR)) and candidate gene single-nucleotide polymorphism
 markers (SNPs) to characterize the genetic architecture and patterns of
 interspecific gene flow in the Picea glauca × P. engelmannii hybrid zone
 across a broad latitudinal (40–60 degrees) and elevational (350–3500 m)
 range in western North America. Our results revealed a wide and complex
 hybrid zone with broad ancestry levels and low interspecific
 heterozygosity, shaped by asymmetric advanced-generation introgression,
 and low reproductive barriers between parental species. The clinal
 variation based on geographic variables, lack of concordance in clines
 among loci and the width of the hybrid zone points towards the maintenance
 of species integrity through environmental selection. Congruency between
 geographic and genomic clines suggests that loci with narrow clines are
 under strong selection, favoring either one parental species (directional
 selection) or their hybrids (overdominance) as a result of strong
 associations with climatic variables such as precipitation as snow and
 mean annual temperature. Cline movement due to past demographic events
 (evidenced by allelic richness and heterozygosity shifts from the average
 cline center) may explain the asymmetry in introgression and predominance
 of P. engelmannii found in this study. These results provide insights into
 the genetic architecture and fine-scale patterns of admixture, and
 identify loci that may be involved in reproductive barriers between the
 species.

title: Data from: Vitamin D status among Thai school children and the association with 1,25-dihydroxyvitamin D and parathyroid hormone levels

description: In several low latitude countries, vitamin D deficiency is emerging as a
 public health issue. Adequate vitamin D is essential for bone health in
 rapidly growing children. In the Thai population, little is known about
 serum 25-hydroxyvitamin D [25(OH)D] status of infants and children.
 Moreover, the association between 25(OH)D and the biological active form
 of 1,25-dihydroxyvitamin D [1,25(OH)]2D is not clear. The specific aims of
 this study were to characterize circulating serum 25(OH)D, 1,25(OH)2D and
 their determinants including parathyroid hormone (PTH), age, sex, height
 and body mass index (BMI) in 529 school-aged Thai children aged 6–14 y.
 Adjusted linear regression analysis was performed to examine the impact of
 age and BMI, and its interaction with sex, on serum 25(OH)D concentrations
 and 1,25(OH)2D concentrations. Serum 25(OH)D, 1,25(OH)2D and PTH
 concentrations (geometric mean ± geometric SD) were 72.7±1.2 nmol/L,
 199.1±1.3 pmol/L and 35.0±1.5 ng/L, respectively. Only 4% (21 of 529)
 participants had a serum 25(OH)D level below 50 nmol/L. There was
 statistically significant evidence for an interaction between sex and age
 with regard to 25(OH)D concentrations. Specifically, 25(OH)D
 concentrations were 19% higher in males. Moreover, females experienced a
 statistically significant 4% decline in serum 25(OH)D levels for each
 increasing year of age (P = 0.001); no decline was seen in male
 participants with increasing age (P = 0.93). When BMI, age, sex, height
 and serum 25(OH)D were individually regressed on 1,25(OH)2D, height and
 sex were associated with 1,25(OH)2D with females exhibiting statistically
 significantly higher serum 1,25(OH)2D levels compared with males
 (P&lt;0.001). Serum 1,25(OH)2D among our sample of children exhibiting
 fairly sufficient vitamin D status were higher than previous reports
 suggesting an adaptive mechanism to maximize calcium absorption.

title: Data from: Fenced and fragmented: conservation value of managed metapopulations

description: Population fragmentation is threatening biodiversity worldwide. Species
 that once roamed vast areas are increasingly being conserved in small,
 isolated areas. Modern management approaches must adapt to ensure the
 continued survival and conservation value of these populations. In South
 Africa, a managed metapopulation approach has been adopted for several
 large carnivore species, all protected in isolated, relatively small,
 reserves that are fenced. As far as possible these approaches are based on
 natural metapopulation structures. In this network, over the past 25
 years, African lions (Panthera leo) were reintroduced into 44 fenced
 reserves with little attention given to maintaining genetic diversity. To
 examine the situation, we investigated the current genetic provenance and
 diversity of these lions. We found that overall genetic diversity was
 similar to that in a large national park, and included a mixture of four
 different southern African evolutionarily significant units (ESUs). This
 mixing of ESUs, while not ideal, provides a unique opportunity to study
 the impact of mixing ESUs over the long term. We propose a strategic
 managed metapopulation plan to ensure the maintenance of genetic diversity
 and improve the long-term conservation value of these lions. This managed
 metapopulation approach could be applied to other species under similar
 ecological constraints around the globe.

title: Data from: Geographic variation of parasitic and predatory traces on mollusks in the northern Adriatic Sea, Italy: implications for the stratigraphic paleobiology of biotic interactions

description: Parasitic trematode worms leave characteristic pits in their bivalve
 mollusk hosts and represent an ideal system for analyzing parasite-host
 interactions through space and time with statistically meaningful sample
 sizes. Previous work in Late Pleistocene–Holocene sequences from the Po
 plain revealed significant long-term fluctuations in trematode prevalence
 values: higher prevalence in retrogradational environments (TST) and
 negligible prevalence in progradational environments (HST). Here we expand
 upon this work by investigating traces of parasitism, kleptoparasitism,
 and predation on mollusk death assemblages from two domains along the
 northern Adriatic coastline. The domain north of the Po delta (TST-like)
 and the southern domain (including the Po delta; HST-like) comprise
 environments comparable to those recovered in late Holocene (&lt;6
 Kyr) subsurface progradational deposits. We collected 17,299 specimens
 representing 111 species from 11 locations on the northern Adriatic coast
 of Italy. Our results reveal high predation pressure, a high diversity of
 host taxa, and widespread presence of trematode infestation in starved,
 oligotrophic, environmentally more stable (i.e., TST-like) settings north
 of the Po delta. Immediately south of the Po delta, in settings with
 strong and variable sedimentary input, almost no infestation is recorded.
 The reappearance of infestation is evident in the southern portion of the
 study area (i.e., Cattolica-Montemarciano), relatively far from the highly
 stressed environments south of the Po River. There is no significant
 difference in trematode prevalence values between fossil and modern
 samples. The distribution of spionid traces (an indicator of stressed
 environments) was nearly the opposite of that displayed by trematodes.
 Drilling frequency is highest in TST-like environments and is not
 correlated with diversity indices. These results suggest that temporal
 trends of trematode prevalence (and possibly also other biotic
 interactions) in sedimentary successions are controlled by environmental
 changes driven by glacio-eustatic dynamics, and reaffirm the importance of
 interpreting temporal trends in the context of spatial variation.

title: Data from: No evidence of sibling cooperation in the absence of parental care in Nicrophorus vespilloides

description: Interactions among siblings fall on a continuum with competition and
 cooperation at opposite ends of the spectrum. Prior work on the burying
 beetle Nicrophorus vespilloides suggests that parental care shifts the
 balance between competition and cooperation by masking a density-dependent
 shift from cooperation to competition. However, these results should be
 interpreted with caution because they were based on correlational evidence
 for an association between larval density at dispersal and mean larval
 mass at dispersal. Here we test for a causal effect of the initial number
 of larvae in a brood on the larvae’s subsequent performance (i.e.,
 survival and mass) in the absence of care. We find no effect of the
 initial larval density on mean larval mass. Thus, our results provide no
 evidence for sibling cooperation in the absence of care in this species.
 However, using larval density at dispersal as a predictor of mean larval
 mass at dispersal, there was a significant correlation between larval
 density and mean larval mass. Our study highlights the importance of using
 experimental designs that exclude confounding effects due to shared
 environmental conditions that otherwise could be misinterpreted as
 evidence for sibling cooperation.

title: Data from: Biparental chloroplast inheritance leads to rescue from cytonuclear incompatibility

description: Although organelle inheritance is predominantly maternal across animals
 and plants, biparental chloroplast inheritance has arisen multiple times
 in the angiosperms. Biparental inheritance has the potential to impact the
 evolutionary dynamics of cytonuclear incompatibility, interactions between
 nuclear and organelle genomes that are proposed to be among the earliest
 types of genetic incompatibility to arise in speciation. We examine the
 interplay between biparental inheritance and cytonuclear incompatibility
 in Campanulastrum americanum, a plant species exhibiting both traits. We
 first determine patterns of chloroplast inheritance in genetically similar
 and divergent crosses, and then associate inheritance with hybrid survival
 across multiple generations. There is substantial biparental inheritance
 in C. americanum. The frequency of biparental inheritance is greater in
 divergent crosses and in the presence of cytonuclear incompatibility.
 Biparental inheritance helps to mitigate cytonuclear incompatibility,
 leading to increased fitness of F1 hybrids and recovery in the F2
 generation. This study demonstrates the potential for biparental
 chloroplast inheritance to rescue cytonuclear compatibility, reducing
 cytonuclear incompatibility's contribution to reproductive isolation
 and potentially slowing speciation. The efficacy of rescue depended upon
 the strength of incompatibility, with a greater persistence of weak
 incompatibilities in later generations. These findings suggest that
 incompatible plastids may lead to selection for biparental inheritance.

title: Data from: Prudent behavior rather than chemical deception enables a parasite to exploit its ant host

description: Many parasites display complex strategies to evade host detection. The
 principal view is that parasites of social insects deceive their host by
 means of advanced chemical adaptations such as mimicking the cuticular
 host recognition cues, being chemically odorless, or emitting manipulative
 volatiles. Apart from these chemical adaptations, parasites of social
 insects may also use simpler behavioral strategies to evade host
 detection. As yet, such behavior has rarely been studied. Here we tested
 which chemical and behavioral strategies the unspecialized parasitic rove
 beetle Thiasophila angulata uses to avoid detection by its aggressive
 Formica rufa red wood ant host. Chemical comparisons of the beetle’s and
 the host ants’ cuticular hydrocarbons showed that the beetle carried an
 idiosyncratic cuticular profile that was clearly different from that of
 its host. Beetles that were isolated from their host or were placed in the
 nests of another Formica species perfectly retained their original
 cuticular profiles and provoked equal levels of aggression. These results
 suggest that the beetles do not avoid host detection through chemical
 deception. In contrast, the beetle adapted its behavior to avoid
 aggression by the ants. In the presence of ants, the beetle behaved much
 more prudently by hiding more frequently and engaging in less risky runs.
 Overall, these results highlight that for relatively unspecialized
 parasites, general strategies such as prudent behavior can be equally
 effective as more specialized deception strategies to evade host
 detection.

title: Data from: Farmer preferences for conservation incentives that promote voluntary phosphorus abatement in agricultural watersheds

description: Financial incentives are commonly used to promote voluntary adoption of
 agricultural best management practices (BMPs), but little is known about
 farmer preferences among alternative incentives. Using experimental
 procurement auctions, we evaluate how different conservation incentives
 affect farmer willingness to adopt BMPs that reduce phosphorus (P) runoff,
 a major driver of harmful algal blooms in Lake Erie. We rank incentives
 (e.g., payment, BMP insurance, tax credit, and certification price
 premium) by the cost per pound of P runoff reduction. Payments and tax
 credits that target high impact areas of the watershed are more
 cost-effective than untargeted price premiums for product certification.
 Farmers demand higher payments for contracts offering BMP insurance (i.e.,
 protection against yield loss from BMP use) due to uncertainty about how
 the program will be implemented and the reliability of indemnities, as
 well as anticipated transaction costs associated with the program.
 Understanding farmer preferences for different types of conservation
 incentives is critical to design agri-environmental programs that engage
 more farmers and cost-effectively enhance ecosystem services.

title: Data from: Glaciations, gradients, and geography: multiple drivers of diversification of bush frogs in the Western Ghats Escarpment

description: The historical processes underlying high diversity in tropical
 biodiversity hotspots like the Western Ghats of Peninsular India remain
 poorly understood. We sampled bush frogs on 13 massifs across the Western
 Ghats Escarpment and examined the relative influence of Quaternary
 glaciations, ecological gradients and geological processes on the spatial
 patterns of lineage and clade diversification. The results reveal a large
 in situ radiation (more than 60 lineages), exhibiting geographical
 structure and clade-level endemism, with two deeply divergent sister
 clades, North and South, highlighting the biogeographic significance of an
 ancient valley, the Palghat Gap. A majority of the bush frog sister
 lineages were isolated on adjacent massifs, and signatures of range stasis
 provide support for the dominance of geological processes in allopatric
 speciation. In situ diversification events within the montane zones (more
 than 1800 m) of the two highest massifs suggest a role for
 climate-mediated forest-grassland persistence. Independent transitions
 along elevational gradients among sub-clades during the Miocene point to
 diversification along the elevational gradient. The study highlights the
 evolutionary significance of massifs in the Western Ghats with the high
 elevations acting as centres of lineage diversification and the low- and
 mid-elevations of the southern regions, with deeply divergent lineages,
 serving as museums.
