title: Data from: Risk of cache pilferage determines hoarding behavior of rodents and seed fate

description: Cache pilferage by competitors is thought to drive the evolution of
 hoarding behavior in animals, which plays significant roles in tree
 regeneration and formation of mutualisms between trees and animals.
 However, little is known how cache pilferage risk among seeds of different
 tree species or years affects hoarding behavior and seed dispersal by
 animals. We hypothesized that scatter-hoarding rodents could adjust
 hoarding behavior according to variation in cache pilferage risk among
 seeds and years to minimize cache pilferage, by investigating the
 relationship between cache pilferage risk and seed dispersal of seven tree
 species over three years in tropical forest in southwest China. Among
 years, high pilferage risk was related to high probability of
 larder-hoarding and short periods of scatter-hoarding; whereas, the
 probability of scatter-hoarding was higher in intermediate pilferage year
 than in both low and high pilferage years. Among seeds, high pilferage
 risk was related to low probability and short periods of scatter-hoarding.
 Our results indicated that cache pilferage risk significantly affected
 hoarding behaviors and seed dispersal by scatter-hoarding rodents as well
 as seed fates. Cache pilferage risk was a reliable explanatory factor for
 variation in seed dispersal, and it might be an important driving force in
 the evolution of rodent hoarding behaviors and seed characteristics.

title: Data from: The shape of success in a turbulent world: wave exposure filtering of coral reef herbivory

description: While environmental filters are well-known factors influencing community
 assembly, the extent to which these modify species functions, and entire
 ecosystem processes, is poorly understood. Focusing on a high-diversity
 system, we ask whether environmental filtering has ecosystem-wide effects
 beyond community assembly. We characterise a coral reef herbivorous fish
 community for swimming performance based on ten functional traits derived
 from fish morphology. We then investigate whether wave exposure modifies
 the functional make-up of herbivory, and the absolute and relative feeding
 frequency of distinct feeding functional groups. Herbivorous fish species
 conformed to either laterally compressed or fusiform body plans, which
 differ in their morphological design to minimise drag. High wave exposure
 selectively limited the feeding function of the deepest body shapes with
 highest caudal thrust efficiency, and favoured fusiform bodies
 irrespective of pectoral fin shape. Traditionally recognised herbivore
 feeding functional groups (i.e. grazers–detritivores and scrapers–small
 excavators) differed in swimming performance, and in their capacity to
 feed consistently across levels of wave exposure. We therefore emphasise
 the distinctness of their ecological niche and functional complementarity.
 Species within the same feeding functional group also had contrasting
 responses to wave exposure. We thereby reveal a further ecological
 dimension of niche partitioning, and reiterate the risk of assuming
 functional redundancy among species with a common feeding mode.
 Contrasting responses of species within feeding functional roles (i.e.
 response diversity) allowed the preservation of critical trophic functions
 throughout the gradient (e.g. macroalgal browsing), and likely explained
 why overall levels of herbivory were robust to filtering. Whether
 ecosystem functioning will remain robust under the additive effects of
 environmental stress and human-induced disturbances remains to be tested.

title: Data from: Return of a giant: DNA from archival museum samples helps to identify a unique cutthroat trout lineage formerly thought to be extinct

description: Currently one small, native population of the culturally and ecologically
 important Lahontan cutthroat trout (Oncorhynchus clarkii henshawi, LCT,
 Federally listed) remains in the Truckee River watershed of northwestern
 Nevada and northeastern California. The majority of populations in this
 watershed were extirpated in the 1940’s due to invasive species,
 overharvest, anthropogenic water consumption and changing precipitation
 regimes. In 1977, a population of cutthroat trout discovered in the Pilot
 Peak Mountains in the Bonneville basin of Utah, was putatively identified
 as the extirpated LCT lacustrine lineage native to Pyramid Lake in the
 Truckee River basin based upon morphological and meristic characters. Our
 phylogenetic and Bayesian genotype clustering analyses of museum specimens
 collected from the large lakes (1872-1913) and contemporary samples
 collected from populations throughout the extant range provide evidence in
 support of a genetically distinct Truckee River basin origin for this
 population. Analysis of museum samples alone identified three distinct
 genotype clusters and historical connectivity among water bodies within
 the Truckee River basin. Baseline data from museum collections indicate
 that the extant Pilot Peak strain represents a remnant of the extirpated
 lacustrine lineage. Given the limitations on high quality data when
 working with a sparse number of preserved museum samples, we acknowledge
 that, in the end, this may be a more complicated story. However, the
 paucity of remnant populations in the Truckee River watershed in
 combination with data on the distribution of morphological, meristic and
 genetic data for Lahontan cutthroat trout, suggest that recovery
 strategies, particularly in the large lacustrine habitats should consider
 this lineage as an important part of the genetic legacy of this species.

title: Data from: Optimization of parameters in cylindrical and surface grinding for improved surface finish

description: Surface integrity has attracted attention of the researchers for improving
 the functional performance of the engineering products. Improvement in
 surface finish, one of the important parameters in surface integrity, has
 been attempted by researchers through different processes. Grinding has
 been widely used for final machining of components requiring smooth
 surfaces coupled with precise tolerances. Proper selection of grinding
 wheel material and grade with grinding parameters can result in improved
 surface finish improved surface characteristics. Present work reports the
 study of the effect of grinding parameters on surface finish of EN8 steel.
 Experiments were performed on surface grinding and cylindrical attachment
 for optimization of grinding process parameters for improved surface
 finish. Grinding wheel speed, depth of cut, table feed, grinding wheel
 material and table travel speed for surface grinding operation and work
 speed for cylindrical grinding operation were taken as the input
 parameters with four types of grinding wheels (Al2O3 of grade K and L, and
 white alumina of grade J and K). The surface roughness was taken as output
 parameter for experimentation. The grinding wheel material and grade have
 been observed as the most significant variables for both the cylindrical
 grinding and surface of grinding. Surface roughness in case of surface
 grinding is better compared to cylindrical grinding which can be
 attributed to vibrations produced in the cylindrical grinding attachment.
 Surface roughness (Ra) value of 0.757 µm in cylindrical grinding and 0.66
 µm in surface grinding has been achieved.

title: Data from: Establishing a community-wide DNA barcode library as a new tool for arctic research

description: DNA sequences offer powerful tools for describing the members and
 interactions of natural communities. In this study, we establish the
 to-date most comprehensive library of DNA barcodes for a terrestrial site,
 including all known macroscopic animals and vascular plants of an
 intensively studied area of the High Arctic, the Zackenberg Valley in
 Northeast Greenland. To demonstrate its utility, we apply the library to
 identify nearly 20 000 arthropod individuals from two Malaise traps, each
 operated for two summers. Drawing on this material, we estimate the
 coverage of previous morphology-based species inventories, derive a
 snapshot of faunal turnover in space and time and describe the abundance
 and phenology of species in the rapidly changing arctic environment.
 Overall, 403 terrestrial animal and 160 vascular plant species were
 recorded by morphology-based techniques. DNA barcodes (CO1) offered high
 resolution in discriminating among the local animal taxa, with 92% of
 morphologically distinguishable taxa assigned to unique Barcode Index
 Numbers (BINs) and 93% to monophyletic clusters. For vascular plants,
 resolution was lower, with 54% of species forming monophyletic clusters
 based on barcode regions rbcLa and ITS2. Malaise catches revealed 122 BINs
 not detected by previous sampling and DNA barcoding. The insect community
 was dominated by a few highly abundant taxa. Even closely related taxa
 differed in phenology, emphasizing the need for species-level resolution
 when describing ongoing shifts in arctic communities and ecosystems. The
 DNA barcode library now established for Zackenberg offers new scope for
 such explorations, and for the detailed dissection of interspecific
 interactions throughout the community.

title: Data from: The metabolic costs of sexual signalling in the chirping katydid Plangia graminea (Serville) (Orthoptera: Tettigoniidae) are context dependent: cumulative costs add up fast

description: Katydids produce acoustic signals via stridulation which they use to
 attract conspecific females for mating. However, direct estimates of the
 metabolic costs of calling to date have produced diverse cost estimates
 and are limited to only a handful of insect species. In this study, we
 therefore investigated the metabolic cost of calling in a unstudied
 sub-Saharan katydid, Plangia graminea. Using wild-caught animals, we
 measured katydid metabolic rate using standard flow-through respirometry
 while simultaneously recording the number of calls produced. Overall, the
 metabolic rate during calling in P. graminea males was 59% higher than the
 resting metabolic rate (0.443±0.056 vs. 0.279±0.028 CO2 ml g−1 h−1)
 although highly variable among individuals. While individual call costs
 were relatively inexpensive (ranging from 0.02–5.4% increase in metabolic
 rate per call) the individuals with cheaper calls called more often and
 for longer than those with expensive calls resulting in the former group
 having significantly greater cumulative costs over a standard amount of
 time (9.5 h). The metabolic costs of calling are however context dependent
 since the amount of time spent calling greatly influenced these costs in
 our trials. A power law function described this relationship between
 cumulative cost and percentage increase per call (y=130.21x−1.068,
 R2=0.858); where y=cumulative cost, and x=percentage increase per call.
 The choice of metric employed for estimating energy costs (i.e. how costs
 are expressed) also affects the outcome and any interpretation of costs of
 sexual signalling. For example, the absolute, relative and cumulative
 metabolic costs of calling yield strongly divergent estimates and any
 fitness implications depend on the organism's energy budget and the
 potential trade-offs in allocation of resources that are made as a direct
 consequence of increased calling effort.

title: Data from: Effects of temperature on consumer-resource interactions

description: 1. Understanding how temperature variation influences the negative (e.g.,
 self-limitation) and positive feedback (e.g., saturating functional
 responses) processes that characterize consumer-resource interactions is
 an important research priority. Previous work on this topic has yielded
 conflicting outcomes with some studies predicting that warming should
 increase consumer-resource oscillations and others predicting that warming
 should decrease consumer-resource oscillations. 2. Here I develop a
 consumer-resource model that both synthesizes previous findings in a
 common framework and yields novel insights about temperature effects on
 consumer-resource dynamics. I report three key findings. First, when the
 resource species' birth rate exhibits a unimodal temperature
 response, as demonstrated by a large number of empirical studies, the
 temperature range over which the consumer-resource interaction can persist
 is determined by the lower and upper temperature limits to the resource
 species' reproduction. This contrasts with the predictions of
 previous studies, which assume that the birth rate exhibits a monotonic
 temperature response, predict that consumer extinction is determined by
 temperature effects on consumer species' traits, rather than the
 resource species' traits. 3. Second, the comparative analysis I have
 conducted shows that whether warming leads to an increase or decrease in
 consumer-resource oscillations depends on the manner in which temperature
 affects intra-specific competition. When the strength of self-limitation
 increases monotonically with temperature, warming causes a decrease in
 consumer-resource oscillations. However, if self-limitation is strongest
 at temperatures physiologically optimal for reproduction, a scenario
 previously unanalyzed by theory but amply substantiated by empirical data,
 warming can cause an increase in consumer-resource oscillations. 4. Third,
 the model yields testable comparative predictions about consumer-resource
 dynamics under alternative hypotheses for how temperature affects
 competitive and resource acquisition traits. Importantly, it does so
 through empirically quantifiable metrics for predicting temperature
 effects on consumer viability and consumer-resource oscillations, which
 obviates the need for parameterizing complex dynamical models. Tests of
 these metrics with empirical data on a host-parasitoid interaction yield
 realistic estimates of temperature limits for consumer persistence and the
 propensity for consumer-resource oscillations, highlighting their utility
 in predicting temperature effects, particularly warming, on
 consumer-resource interactions in both natural and agricultural settings.

title: Data from: Relationships between invasion success and colony breeding structure in a subterranean termite

description: Factors promoting the establishment and colonization success of introduced
 populations in new environments constitute an important issue in
 biological invasions. In this context, the respective role of
 pre-adaptation and evolutionary changes during the invasion process is a
 key question that requires particular attention. This study compared the
 colony breeding structure (i.e. number and relatedness among reproductives
 within colonies) in native and introduced populations of the subterranean
 pest termite, Reticulitermes flavipes. We generated and analysed a data
 set of both microsatellite and mtDNA loci on termite samples collected in
 three introduced populations, one in France and two in Chile, and in the
 putative source population of French and Chilean infestations that has
 recently been identified in New Orleans, LA. We also provided a synthesis
 combining our results with those of previous studies to obtain a global
 picture of the variation in breeding structure in this species. Whereas
 most native US populations are mainly composed of colonies headed by
 monogamous pairs of primary reproductives, all introduced populations
 exhibit a particular colony breeding structure that is characterized by
 hundreds of inbreeding reproductives (neotenics) and by a propensity of
 colonies to fuse, a pattern shared uniquely with the population of New
 Orleans. These characteristics are comparable to those of many invasive
 ants and are discussed to play an important role during the invasion
 process. Our finding that the New Orleans population exhibits the same
 breeding structure as its related introduced populations suggests that
 this native population is pre-adapted to invade new ranges.

title: Data from: A newly identified left–right asymmetry in larval sea urchins

description: Directional asymmetry (DA) in body form is a widespread phenomenon in
 animals and plants alike, and a functional understanding of such
 asymmetries can offer insights into the ways in which ecology and
 development interface to drive evolution. Echinoids (sea urchins, sand
 dollars and their kin) with planktotrophic development have a bilaterally
 symmetrical feeding pluteus larva that undergoes a dramatic metamorphosis
 into a pentameral juvenile that enters the benthos at settlement. The
 earliest stage of this transformation involves a DA: a left-side
 invagination in mid-stage larvae leads to the formation of the oral field
 of the juvenile via a directionally asymmetric structure called the
 echinus rudiment. Here, we show for the first time in two echinoid species
 that there is a corresponding DA in the overall shape of the larva:
 late-stage plutei have consistently shorter arms specifically on the
 rudiment (left) side. We then demonstrate a mechanistic connection between
 the rudiment and arm length asymmetries by examining rare, anomalous
 purple urchin larvae that have rudiments on both the left and the right
 side. Our data suggest that this asymmetry is probably a broadly shared
 feature characterizing ontogeny in the class Echinoidea. We propose
 several functional hypotheses—including developmental constraints and
 water column stability—to account for this newly identified asymmetry.

title: Data from: Sources of variance in a female fertility signal: exaggerated estrous swellings in a natural population of baboons

description: Signals of fertility in female animals are of increasing interest to
 evolutionary biologists, a development that coincides with increasing
 interest in male mate choice and the potential for female traits to evolve
 under sexual selection. We characterized variation in size of an
 exaggerated female fertility signal in baboons and investigated the
 sources of that variance. The number of sexual cycles that a female had
 experienced after her most recent pregnancy (“cycles since resumption”)
 was the strongest predictor of swelling size. Furthermore, the
 relationship between cycles since resumption and swelling size was most
 evident during rainy periods and was not evident during times of drought.
 Finally, we found significant differences in swelling size between
 individual females; these differences endured across cycles (i.e., were
 not explained by variation within individuals) and persisted in spite of
 ecological effects. This study is the first to provide conclusive evidence
 of significant variation in swelling size between female primates
 (controlling for cycles since resumption) and to demonstrate that
 ecological constraints influence variation in this signal of fertility.

title: Data from: Evaluating the potential for pre-zygotic isolation and hybridization between landlocked and anadromous alewife (Alosa pseudoharengus) following secondary contact

description: The recent increase of river restoration projects is altering habitat
 connectivity for many aquatic species, increasing the chance that
 previously isolated populations will come into secondary contact.
 Anadromous and landlocked alewife (Alosa pseudoharengus) are currently
 undergoing secondary contact as a result of a fishway installation at
 Rogers Lake in Old Lyme, Connecticut. To determine the degree of
 pre-zygotic isolation and potential for hybridization between alewife life
 history forms, we constructed spawning time distributions for two
 anadromous and three landlocked alewife populations using otolith derived
 age estimates. In addition, we analyzed long-term data from anadromous
 alewife migratory spawning runs to look for trends in arrival date and
 spawning time. Our results indicated that anadromous alewife spawned
 earlier and over a shorter duration than landlocked alewife, but 3% to 13%
 of landlocked alewife spawning overlapped with the anadromous alewife
 spawning period. The degree of spawning time overlap was primarily driven
 by annual and population level variation in the timing of spawning by
 landlocked alewife, whereas the timing and duration of spawning for
 anadromous alewife was found to be relatively invariant among years in our
 study system. For alewife and many other anadromous fish species, the
 increase in fish passage river restoration projects in the coming decades
 will re-establish habitat connectivity and may bring isolated populations
 into contact. Hybridization between life history forms may occur when
 pre-zygotic isolating mechanisms are minimal, leading to potentially rapid
 ecological and evolutionary changes in restored habitats.
