title: Data from: Female Salix viminalis are more severely infected by Melampsora spp. but neither sex experiences associational effects

description: Associational effects of plant genotype or species on plant biotic
 interactions are common, not least for disease spread, but associational
 effects of plant sex on interactions have largely been ignored. Sex in
 dioecious plants can affect biotic interactions with herbivores and
 pollinators; however, its effects on plant–pathogen interactions are
 understudied and associational effects are unknown. In a replicated field
 experiment, we assessed Melampsora spp. leaf rust infection in monosexual
 and mixed sex plots of dioecious Salix viminalis L. to determine whether
 plant sex has either direct or associational effects on infection
 severity. We found no differences in Melampsora spp. infection severity
 among sexual monocultures and mixtures in our field experiment. However,
 female plants were overall more severely infected. In addition, we
 surveyed previous studies of infection in S. viminalis clones and
 reevaluated the studies after we assigned sex to the clones. We found that
 females were generally more severely infected, as in our field study.
 Similarly, in a survey of studies on sex-biased infection in dioecious
 plants, we found more female-biased infections in plant–pathogen pairs. We
 conclude that there was no evidence for associational plant sex effects of
 neighboring conspecifics for either females or males on infection
 severity. Instead, plant sex effects on infection act at an individual
 plant level. Our findings also suggest that female plants may in general
 be more severely affected by fungal pathogens than males.

title: Data from: Demographic drivers of age-dependent sexual selection

description: Sexual selection has a critical role in evolution, and it is fundamental
 to identify what ecological factors drive its variation. Disentangling the
 ecological correlates of sexual selection over the long term, however, is
 challenging and has rarely been done in nature. We sought to assess how
 demographic changes influenced the intensity, direction and form of sexual
 selection and whether selective pressures varied with age. We tested
 whether breeder sex ratio, number of competitors and age structure
 influenced selection differentials on horn length of wild bighorn rams
 (Ovis canadensis) of different age classes on Ram Mountain, Alberta. We
 used 21 years of data including a detailed pedigree, demographic
 parameters and repeated morphological measurements. Sexual selection on
 horn length of males of all ages was directional and positive. Selection
 intensity increased with the number of competitors, reflecting male–male
 encounter rate during the rut, but was independent of breeder sex ratio or
 age structure. This result can also be linked to changes in population
 size because the number of competitors was highly correlated to total
 number of sheep. This demographic effect likely arises from age-dependent
 mating tactics. Males aged 2–4 years are weakly competitive and
 experienced stronger sexual selection as they accounted for a greater
 proportion of all males. Selection experienced by mature males appeared
 independent of demography. Our study provides a rare description of the
 demographic determinants of sexual selection in nature.

title: Data from: Quantifying Susceptibility of Marine Invertebrate Biocomposites to Dissolution in Reduced pH

description: Ocean acidification threatens many ecologically and economically important
 marine calcifiers. The increase in shell dissolution under the resulting
 reduced pH is an important and increasingly recognised threat. The
 biocomposites that make up calcified hardparts have a range of
 taxon-specific compositions and microstructures, and it is evident that
 these may influence susceptibilities to dissolution. Here, we show how
 dissolution (thickness loss) under both ambient and predicted end-century
 pH (≈7.6) varies between seven different bivalve mollusc and one
 crustacean biocomposite and investigate how this relates to details of
 their microstructure and composition. Over 100 days the dissolution of all
 microstructures was greater under the lower pH in the end-century
 conditions. Dissolution of lobster cuticle was greater than for any
 bivalve microstructure, despite its calcite mineralogy, showing the
 importance of other microstructural characteristics besides carbonate
 polymorph. Organic content had the strongest positive correlation with
 dissolution when all microstructures were considered, and together with
 Mg/Ca ratio, explained 80-90% of the variance in dissolution. Organic
 content, Mg/Ca ratio, crystal density and mineralogy were all required to
 explain the maximum variance in dissolution within only bivalve
 microstructures, but still only explained 50-60% of the variation in
 dissolution.

title: Data from: Acceptance threshold theory can explain occurrence of homosexual behaviour

description: Same-sex sexual behaviour (SSB) has been documented in a wide range of
 animals, but its evolutionary causes are not well understood. Here, we
 investigated SSB in the light of Reeve's acceptance threshold theory.
 When recognition is not error-proof, the acceptance threshold used by
 males to recognize potential mating partners should be flexibly adjusted
 to maximize the fitness pay-off between the costs of erroneously accepting
 males and the benefits of accepting females. By manipulating male burying
 beetles' search time for females and their reproductive potential, we
 influenced their perceived costs of making an acceptance or rejection
 error. As predicted, when the costs of rejecting females increased, males
 exhibited more permissive discrimination decisions and showed high levels
 of SSB; when the costs of accepting males increased, males were more
 restrictive and showed low levels of SSB. Our results support the idea
 that in animal species, in which the recognition cues of females and males
 overlap to a certain degree, SSB is a consequence of an adaptive
 discrimination strategy to avoid the costs of making rejection errors.

title: Data from: Ecological drift and the distribution of species diversity

description: Ecological drift causes species abundances to fluctuate randomly, lowering
 diversity within communities and increasing differences among otherwise
 equivalent communities. Despite broad interest in ecological drift,
 ecologists have little experimental evidence of its consequences in
 nature, where competitive forces modulate species abundances. We
 manipulated drift by imposing 40-fold variation in the size of
 experimentally assembled annual plant communities and holding their
 edge-to-interior ratios comparable. Drift over three generations was
 greater than predicted by neutral models, causing high extinction rates
 and fast divergence in composition among smaller communities. Competitive
 asymmetries drove populations of most species to small enough sizes that
 demographic stochasticity could markedly influence dynamics, increasing
 the importance of drift in communities. The strong effects of drift
 occurred despite stabilizing niche differences, which cause species to
 have greater population growth rates when at low local abundance. Overall,
 the importance of ecological drift appears greater in non-neutral
 communities than previously recognized, and varies with community size and
 the type and strength of density dependence.

title: Data from: Positive effects of non-native grasses on the growth of a native annual in a southern California ecosystem

description: Fire disturbance is considered a major factor in the promotion of
 non-native plant species. Non-native grasses are adapted to fire and can
 alter environmental conditions and reduce resource availability in native
 coastal sage scrub and chaparral communities of southern California. In
 these communities persistence of non-native grasses following fire can
 inhibit establishment and growth of woody species. This may allow certain
 native herbaceous species to colonize and persist beneath gaps in the
 canopy. A field manipulative experiment with control, litter, and bare
 ground treatments was used to examine the impact of non-native grasses on
 growth and establishment of a native herbaceous species, Cryptantha
 muricata. C. muricata seedling survival, growth, and reproduction were
 greatest in the control treatment where non-native grasses were present.
 C. muricata plants growing in the presence of non-native grasses produced
 more than twice the number of flowers and more than twice the reproductive
 biomass of plants growing in the treatments where non-native grasses were
 removed. Total biomass and number of fruits were also greater in the
 plants growing in the presence of non-native grasses. Total biomass and
 reproductive biomass was also greater in late germinants than early
 germinants growing in the presence of non-native grasses. This study
 suggests a potential positive effect of non-native grasses on the
 performance of a particular native annual in a southern California
 ecosystem.

title: Data from: Clinical and metabolic characteristics among Mexican children with different types of diabetes mellitus

description: Background: Current classification of diabetes mellitus (DM) is based on
 etiology and includes type 1 (T1DM), type 2 (T2DM), gestational, and
 other. Clinical and pathophysiological characteristics of T1DM and T2DM in
 the same patient have been designated as type 1.5 DM (T1.5DM). Objectives:
 The aim of this study was to classify pediatric patients with DM based on
 pancreatic autoimmunity and the presence or absence of overweight/obesity,
 and to compare the clinical, anthropometric, and biochemical
 characteristics between children in the different classes of DM. Methods:
 A sample of 185 patients, recruited (March 2008-April 2015) as part of the
 Cohort of Mexican Children with DM (CMC-DM); ClinicalTrials.gov,
 identifier: NCT02722655. The DM classification was made considering
 pancreatic autoimmunity (via antibodies GAD-65, IAA, and AICA) and the
 presence or absence of overweight/obesity. Clinical, anthropometric and
 biochemical variables, grouped by type of DM were compared (Kruskal-Wallis
 or chi-squared test). Results: The final analysis included 140 children;
 18.57% T1ADM, 46.43% T1BDM, 12.14% T1.5DM, and 22.86% T2DM. Fasting
 C-Peptide (FCP), and hs-CRP levels were higher in T1.5DM and T2DM, and the
 greatest levels were observed in T1.5DM (p&lt;0.001 and 0.024
 respectively). Conclusions: We clearly identified that the etiologic
 mechanisms of T1DM and T2DM are not mutually exclusive, and we detailed
 why FCP levels are not critical for the classification system of DM in
 children. The findings of this study suggest that T1.5DM should be
 considered during the classification of pediatric DM and might facilitate
 more tailored approaches to treatment, clinical care and follow-up.

title: Data from: Sexual selection shapes development and maturation rates in Drosophila

description: Explanations for the evolution of delayed maturity usually invoke
 trade-offs mediated by growth, but processes of reproductive maturation
 often continue long after growth has ceased. Here, we tested whether
 sexual selection shapes the rate of post-eclosion maturation in the fruit
 fly Drosophila melanogaster. We found that populations maintained for more
 than 100 generations under a short generation time and polygamous mating
 system evolved faster post-eclosion maturation and faster egg-to-adult
 development of males, when compared to populations kept under short
 generations and randomized monogamy that eliminated sexual selection. An
 independent assay demonstrated that more mature males have higher fitness
 under polygamy, but this advantage disappears under monogamy. In contrast,
 for females greater maturity was equally advantageous under polygamy and
 monogamy. Furthermore, monogamous populations evolved faster development
 and maturation of females relative to polygamous populations, with no
 detectable trade-offs with adult size or egg-to-adult survival. These
 results suggest that a major aspect of male maturation involves developing
 traits that increase success in sexual competition, whereas female
 maturation is not limited by investment in traits involved in mate choice
 or defense against male antagonism. Moreover, rates of juvenile
 development and adult maturation can readily evolve in opposite directions
 in the two sexes, possibly implicating polymorphisms with sexually
 antagonistic pleiotropy.

title: Data from: Can the source-sink hypothesis explain macrofaunal abundance patterns in the abyss? A modeling test

description: Low food availability is a major structuring force in deep-sea benthic
 communities, sustaining only very low densities of organisms in parts of
 the abyss. These low population densities may result in an Allee effect,
 whereby local reproductive success is inhibited, and populations are
 maintained by larval dispersal from bathyal slopes. This slope–abyss
 source–sink (SASS) hypothesis suggests that the abyssal seafloor
 constitutes a vast sink habitat with macrofaunal populations sustained
 only by an influx of larval ‘refugees' from source areas on
 continental slopes, where higher productivity sustains greater population
 densities. Abyssal macrofaunal population densities would thus be directly
 related to larval inputs from bathyal source populations. We evaluate
 three predictions derived from the SASS hypothesis: (i) slope-derived
 larvae can be passively transported to central abyssal regions within a
 single larval period, (ii) projected larval export from slopes to the
 abyss reproduces global patterns of macrofaunal abundance and (iii)
 macrofaunal abundance decreases with distance from the continental slope.
 We find that abyssal macrofaunal populations are unlikely to be sustained
 solely through influx of larvae from slope sources. Rather, local
 reproduction probably sustains macrofaunal populations in relatively
 high-productivity abyssal areas, which must also be considered as
 potential larval source areas for more food-poor abyssal regions.

title: Data from: Geckos as springs: mechanics explain across-species scaling of adhesion

description: One of the central controversies regarding the evolution of adhesion
 concerns how adhesive force scales as animals change in size, either among
 or within species. A widely held view is that as animals become larger,
 the primary mechanism that enables them to climb is increasing pad area.
 However, prior studies show that much of the variation in maximum adhesive
 force remains unexplained, even when area is accounted for. We tested the
 hypothesis that maximum adhesive force among pad-bearing gecko species is
 not solely dictated by toepad area, but also depends on the ratio of
 toepad area to gecko adhesive system compliance in the loading direction,
 where compliance (C) is the change in extension (Δ) relative to a change
 in force (F) while loading a gecko’s adhesive system (C = dΔ/dF). Geckos
 are well-known for their ability to climb on a range of vertical and
 overhanging surfaces, and range in mass from several grams to over 300
 grams, yet little is understood of the factors that enable adhesion to
 scale with body size. We examined the maximum adhesive force of six gecko
 species that vary in body size (~2–100 g). We also examined changes
 between juveniles and adults within a single species (Phelsuma grandis).
 We found that maximum adhesive force and toepad area increased with
 increasing gecko size, and that as gecko species become larger, their
 adhesive systems become significantly less compliant. Additionally, our
 hypothesis was supported, as the best predictor of maximum adhesive force
 was not toepad area or compliance alone, but the ratio of toepad area to
 compliance. We verified this result using a synthetic “model gecko” system
 comprised of synthetic adhesive pads attached to a glass substrate and a
 synthetic tendon (mechanical spring) of finite stiffness. Our data
 indicate that increases in toepad area as geckos become larger cannot
 fully account for increased adhesive abilities, and decreased compliance
 must be included to explain the scaling of adhesion in animals with dry
 adhesion systems.

title: Data from: Microsatellite evolutionary rate and pattern in Schistocerca gregaria inferred from direct observation of germline mutations

description: Unravelling variation among taxonomic orders regarding the rate of
 evolution in microsatellites is crucial for evolutionary biology and
 population genetics research. The mean mutation rate of microsatellites
 tends to be lower in arthropods than in vertebrates, but data are scarce
 and mostly concern accumulation of mutations in model species. Based on
 parent-offspring segregations and a hierarchical Bayesian model, the mean
 rate of mutation in the orthopteran insect Schistocerca gregaria was
 estimated at 2.1e-4 per generation per untranscribed dinucleotide locus.
 This is close to vertebrate estimates and one order of magnitude higher
 than estimates from species of other arthropod orders, such as Drosophila
 melanogaster and Daphnia pulex. We also found evidence of a directional
 bias towards expansions even for long alleles and exceptionally large
 ranges of allele sizes. Finally, at transcribed microsatellites, the mean
 rate of mutation was half the rate found at untranscribed loci and the
 mutational model deviated from that usually considered, with most
 mutations involving multistep changes that avoid disrupting the reading
 frame. Our direct estimates of mutation rate were discussed in the light
 of peculiar biological and genomic features of S. gregaria, including
 specificities in mismatch repair and the dependence of its activity to
 allele length. Shedding new light on the mutational dynamics of
 grasshopper microsatellites is of critical importance for a number of
 research fields. As an illustration, we showed how our findings improve
 microsatellite application in population genetics, by obtaining a more
 precise estimation of S. gregaria effective population size from a
 published data set based on the same microsatellites.
