title: Data from: Modification of sperm quality after sexual abstinence in Seba's short-tailed bat, Carollia perspicillata.

description: In polygynous mating systems, few males have stable access to sexual
 mates. With an expected higher copulation rate, harem males may deplete
 seminal fluids or increase epididymal sperm maturation, generating poor
 sperm quality. In a first study, we reported a higher sperm quality in
 sneaker males of Carollia perspicillata. To test whether the lower sperm
 quality observed in harem males was generated by an elevated copulation
 rate, we temporarily removed males of both social statuses from the
 colony. We thus assessed status-related changes of sperm quality resulting
 from sexual abstinence. Moreover, released from territory and female
 guarding, harem males were expected to show a reduction in somatic costs.
 On the basis of sperm competition models, we predicted a higher resource
 investment in the ejaculate with the reduction of pre-copulatory efforts.
 In line with our predictions, sperm quality of harem males improved
 significantly in contrast to sneaker males, whose sperm quality did not
 change. Without an increase in ejaculate lipid peroxidation, our results
 also provide evidence that the duration of sexual abstinence was not
 sufficient to generate sperm oxidative damage through senescence. Harem
 males did not show a reduction in blood lipid peroxidation or in the ratio
 of oxidized to reduced glutathione. In line with the maintenance of these
 somatic costs, harem males did not invest more superoxide dismutase to the
 ejaculate to maintain sperm quality. Our results suggest that a difference
 in copulation rate rather than an adaptation to sperm competition provides
 sneaker males with higher sperm quality in C. perspicillata.

title: Data from: Landscape-specific thresholds in the relationship between species richness and natural land cover

description: 1. Thresholds in the relationship between species richness and natural
 land cover can inform landscape-level vegetation protection and
 restoration targets. However, landscapes differ considerably in
 composition and other environmental attributes. If the effect of natural
 land cover on species richness depends on (i.e. interacts with) these
 attributes, and this affects the value of thresholds in this relationship,
 such dependencies must be considered when using thresholds to guide
 landscape management. 2. We hypothesised that the amount of natural land
 cover at which a threshold occurs would differ in predictable ways with
 particular anthropogenic, abiotic and biotic attributes of landscapes. To
 test this, we related woodland bird species richness in 251 landscapes,
 each 100 km 2, to natural land cover in south-east Australia. We compared
 the fit of exponential and threshold models of the richness-natural land
 cover relationship, focussing on the extent of natural land cover at which
 thresholds presented among landscapes that differed in matrix land use
 intensity, heterogeneity, productivity and the prevalence of strong biotic
 interactors. We used linear mixed modelling to examine how interactions
 between natural land cover and the various landscape attributes affected
 the fit of models of species richness. 3. Threshold models of the
 richness-natural land cover relationship were always a better fit than
 exponential models. Threshold values did not vary consistently with
 specific landscape attributes, with the exception of landscapes that were
 classified by the prevalence of strong biotic interactors
 (hypercompetitive native birds of the genus Manorina). 4. Natural land
 cover had a more positive effect on species richness in landscapes when
 Manorina prevalence was higher. This positive interaction provided the
 biggest improvement in explanatory power of models of species richness. 5.
 Synthesis and applications. While we detected an interaction between
 Manorina prevalence and the area of natural land cover, generalities
 relating to the underlying nature of thresholds in the richness-natural
 land cover relationship remain elusive. Complex interactions, relating to
 various landscape attributes and associated ecological processes, likely
 underpin variation in threshold values. Until these complexities are
 better understood, the use of thresholds for informing landscape
 management and conservation target setting should be approached with
 caution.

title: Data from: Oxidative damage increases with reproductive energy expenditure and is reduced by food-supplementation

description: A central principle in life-history theory is that reproductive effort
 negatively affects survival. Costs of reproduction are thought to be
 physiologically-based, but the underlying mechanisms remain poorly
 understood. Using female North American red squirrels (Tamiasciurus
 hudsonicus), we test the hypothesis that energetic investment in
 reproduction overwhelms investment in antioxidant protection, leading to
 oxidative damage. In support of this hypothesis we found that the highest
 levels of plasma protein oxidative damage in squirrels occurred during the
 energetically-demanding period of lactation. Moreover, plasma protein
 oxidative damage was also elevated in squirrels that expended the most
 energy and had the lowest antioxidant protection. Finally, we found that
 squirrels that were food-supplemented during lactation and winter had
 increased antioxidant protection and reduced plasma protein oxidative
 damage providing the first experimental evidence in the wild that access
 to abundant resources can reduce this physiological cost.

title: Data from: Phylogenetic signal, feeding behaviour, and brain volume in Neotropical bats

description: Comparative correlational studies of brain size and ecological traits
 (e.g. feeding habits and habitat complexity) have increased our knowledge
 about the selective pressures on brain evolution. Studies conducted in
 bats as a model system assume that shared evolutionary history has a
 maximum effect on the traits. However, this effect has not been
 quantified. In addition, the effect of levels of diet specialization on
 brain size remains unclear. We examined the role of diet on the evolution
 of brain size in Mormoopidae and Phyllostomidae using two comparative
 methods. Body mass explained 89% of the variance in brain volume. The
 effect of feeding behaviour (either characterized as feeding habits, as
 levels of specialization on a type of item or as handling behaviour) on
 brain volume was also significant albeit not consistent after controlling
 for body mass and the strength of the phylogenetic signal (λ). Although
 the strength of the phylogenetic signal of brain volume and body mass was
 high when tested individually, λ values in phylogenetic generalized least
 squares models were significantly different from 1. This suggests that
 phylogenetic independent contrasts models are not always the best approach
 for the study of ecological correlates of brain size in New World bats.

title: Data from: Scale dependence of the diversity–stability relationship in a temperate grassland

description: 1. A positive relationship between biodiversity and ecosystem stability
 has been reported in many ecosystems; however, it has yet to be determined
 whether and how spatial scale affects this relationship. Here, for the
 first time, we assessed the effects of alpha, beta and gamma diversity on
 ecosystem stability and the scale dependence of the slope of the
 diversity–stability relationship. 2. By employing a long-term (33 years)
 dataset from a temperate grassland, northern China, we calculated the all
 possible spatial scales with the complete combination from the basic 1-m2
 plots. 3. Species richness was positively associated with ecosystem
 stability through species asynchrony and overyielding at all spatial
 scales (1, 2, 3, 4, and 5 m2). Both alpha and beta diversity were
 positively associated with gamma stability. 4. Moreover, the slope of the
 diversity–area relationship was significantly higher than that of the
 stability–area relationship, resulting in a decline of the slope of the
 diversity–stability relationship with increasing area. 5. Synthesis. With
 the positive species diversity effect on ecosystem stability from small to
 large spatial scales, our findings demonstrate the need to maintain a high
 biodiversity and biotic heterogeneity as insurance against the risks
 incurred by ecosystems in the face of global environmental changes.

title: Data from: Plasma dipeptidyl peptidase IV activity and measures of body composition in apparently healthy people

description: Aim: Based on its regulatory action on glucagon-like peptide 1, dipeptidyl
 peptidase IV (DPP-IV) has increasingly been linked to Type 2 diabetes.
 However, there is no evidence as to how this normal modulatory enzyme
 leads to pathology. It is thought that DPP-IV is affected by the
 development of obesity, which is a common precursor to Type 2 diabetes.
 Little is known about the relationship between DPP-IV activity in plasma
 and specific body composition measures. Main methods: In the current
 study, plasma DPP-IV activity and body composition measures were collected
 from 111 healthy subjects between the ages of 19 and 70 years old for
 analysis. Key findings: The mean plasma DPP-IV activity was 35.9U/L ±
 12.3, falling within normal reference value range presented by Durinx et
 al. DPP-IV activity was negatively correlated with absolute body fat mass,
 but absolute lean mass was positively correlated. Consistent with the
 findings, DPP-IV activity was also negatively correlated with absolute
 gynoid fat (p = 0.0047). DPP-IV activity did not have a significant
 correlation with absolute android fat mass, visceral adipose tissue, BMI,
 and age. Significance: From these results, it can be concluded that high
 activity of DPP-IV is not indicative of pathology, and specific body
 composition components may influence soluble DPP-IV activity in the blood.

title: Data from: Structural complexity of hunting habitat and territoriality increase the reversed sexual size dimorphism in diurnal raptors

description: Despite numerous efforts and many hypotheses to explain the selective
 pressures that may have favoured reversed sexual dimorphism (RSD) in
 raptors ‐ i.e. that the female is larger than the male ‐ some drivers of
 RSD are still unknown. Here we analyse how much variation in RSD is
 explained by hunting habitat structure, territoriality or territory size.
 We do so using data on diurnal raptors from the New World and the Western
 Palearctic – i.e. Cathartidae, Pandionidae, Accipitridae and Falconidae,
 the largest bird group showing RSD ‐ taking into account the phylogenetic
 relationships among species. Our results identify the type of the main
 prey as a major factor explaining RSD in raptors. We also found RSD to
 increase with increasing structural complexity in the hunting habitat from
 open or semi‐open habitats to forest interior. RSD also increased with
 increasing degree of territoriality of the species (non‐territorial
 &lt; facultative &lt; territorial). Finally, for territorial
 species RSD increased with increasing size of nesting territory. A model
 comprising only three predictor variables (prey type, structural
 complexity of hunting habitat and territoriality) explained up to 50% of
 the variation in RSD of European and American diurnal raptor species, and
 up to 40% of the variation in RSD when only territorial species were
 considered. Our results highlight the relevance of spatial facets of the
 niche – e.g. hunting habitat, territoriality and territory size ‐ in
 exerting selective pressures on the body size of diurnal raptors. These
 selective pressures, joint with already known trophic factors – e.g. diet
 ‐ are decisive for the evolution of the RSD, a key trait in the functional
 ecology of raptors. Our findings open up new perspectives in the study of
 sexual size divergence in birds.

title: Data from: Habitat connectivity is determined by the scale of habitat loss and dispersal strategy

description: Understanding factors that ameliorate the impact of habitat loss is a
 major focus of conservation research. One key factor influencing species
 persistence and evolution is the ability to disperse across increasingly
 patchy landscapes. Here we ask whether interpatch distance (a proxy for
 habitat loss) and dispersal strategy can interact to form thresholds where
 connectivity breaks down. We assayed dispersal across a range of
 interpatch distances in fruit flies carrying allelic variants of a gene
 known to underlie differences in dispersal strategy. Dispersal-limited
 flies experienced a distinct negative threshold in connectivity at greater
 interpatch distances, and this was not observed in more dispersive flies.
 Consequently, this differential response of dispersal-limited and more
 dispersive flies to decreasing connectivity suggests that habitat loss
 could have important implications on the evolution and maintenance of
 genetic variation underlying dispersal strategy.

title: Data from: Australian house geckos are more aggressive than a globally successful invasive Asian house gecko

description: Invasive species are implicated in native species declines globally, but
 predicting the effect of specific invaders on a given native species
 remains difficult. Many successful invaders are highly aggressive, while
 others are not. The highly successful invasive Asian house gecko,
 Hemidactylus frenatus, has achieved a pan-tropical distribution. We
 investigated direct interactions between H. frenatus and a sympatric
 native Australian house gecko (Gehyra dubia) to determine the strength and
 nature of aggressive exclusion, and which species may be competitively
 superior. Intraspecific aggression was strong in the native, and
 individuals were more aggressive as residents than as intruders,
 suggesting this species shows site defence. In contrast, the invasive
 species displayed little aggression in intraspecific encounters. Overall,
 residents of the native species were more aggressive than residents of the
 invasive species. Aggression in the native species was influenced by the
 degree of aggression of the intruding gecko, but not by the species of
 intruder. Aggression from invasive residents was low and was not
 influenced by either the intruder's species or their behavior. Our
 study suggests that native Australian house geckos (Gehyra dubia) are
 unlikely to be directly displaced by invasive H. frenatus, but rather that
 this native gecko will aggressively defend its resources when necessary.
 In this case, the tolerance of the invasive species for others in close
 proximity may contribute to its success.

title: Data from: Antibiotics and the risk of community-associated Clostridium difficile infection (CDI): a meta-analysis

description: The rising incidence of Clostridium difficile infection (CDI) could be
 reduced by lowering exposures to high risk antibiotics. The objective of
 this study was to determine the association between antibiotic class and
 the risk of CDI in the community setting. EMBASE and PubMed were queried
 without restriction to date or language. Comparative observational studies
 and RCTs considering the impact of antibiotic exposures on CDI risk among
 non-hospitalized populations were considered. We estimated pooled odds
 ratios (OR) for antibiotic classes using random effects meta-analysis. Our
 search criteria identified 465 articles, of which 7 met inclusion
 criteria; all were observational studies. Five studies considered
 antibiotic risk relative to no antibiotic exposure: clindamycin (OR=16.80,
 95% confidence interval [CI]: 7.48-37.76), fluoroquinolones (OR=5.50, 95%
 CI: 4.26-7.11) and cephalosporins, monobactams and carbapenems (CMCs,
 OR=5.68, 95% CI: 2.12-15.23) had the largest effects, while macrolides
 (OR=2.65, 95% CI: 1.92-3.64), sulfonamides and trimethoprim (OR=1.81, 95%
 CI: 1.34-2.43) and penicillins (OR=2.71, 95% CI: 1.75-4.21) had lesser
 associations with CDI. We noted no effect of tetracyclines on CDI risk
 (OR=0.92, 95% CI: 0.61-1.40). In the community setting, there is
 substantial variation in risk of CDI associated with different
 antimicrobial classes. Avoidance of high risk antibiotics (such as
 clindamycin, CMCs and fluoroquinolones) in favor of lower risk antibiotics
 (such as penicillins, macrolides and tetracyclines) may help reduce the
 incidence of CDI.

title: Data from: The impact of artificial light at night on nocturnal insects: a review and synthesis

description: In recent decades, advances in lighting technology have precipitated
 exponential increases in night sky brightness worldwide, raising concerns
 in the scientific community about the impact of artificial light at night
 (ALAN) on crepuscular and nocturnal biodiversity. Long-term records show
 that insect abundance has declined significantly over this time, with
 worrying implications for terrestrial ecosystems. The majority of
 investigations into the vulnerability of nocturnal insects to artificial
 light have focused on the flight-to-light behavior exhibited by select
 insect families. However, ALAN can affect insects in other ways as well.
 This review proposes five categories of ALAN impact on nocturnal insects,
 highlighting past research and identifying key knowledge gaps. We conclude
 with a summary of relevant literature on bioluminescent fireflies, which
 emphasizes the unique vulnerability of terrestrial light-based
 communication systems to artificial illumination. Comprehensive
 understanding of the ecological impacts of ALAN on diverse nocturnal
 insect taxa will enable researchers to seek out methods whereby fireflies,
 moths, and other essential members of the nocturnal ecosystem can coexist
 with humans on an increasingly urbanized planet.
description: Effect
 sizeData used to calculate
 effect size (Glass's Δ) of five studies on the impact of artificial
 light at night (ALAN) on firefly occurrence and/or courtship. Values were
 obtained published figures by means of WebPlotDigitizer
 (https://apps.automeris.io/wpd/). Because all studies involve comparison
 of groups of the same size (e.g. firefly populations before and after ALAN
 exposure), Glass’s Δ is an appropriate estimate of effect size, as it uses
 only the standard deviation of the control group (Kline
 2013).

title: Data from: Accuracy of a prey-specific DNA assay and a generic prey-immunomarking assay for detecting predation

description: Predator gut examinations are useful for detecting arthropod predation
 events. The accuracy and reproducibility of two different gut assays are
 tested on various predator species that consumed Chrysoperla carnea
 (Stephens), that was externally labelled with rabbit immunoglobulin (IgG).
 Each predator homogenate was examined in triplicate for prey remains by
 both a conventional PCR assay to detect for C. carnea DNA and a generic
 ELISA to detect for rabbit IgG marked prey. The ability of each method to
 detect predation over time was compared among predators and between assay
 types were determined using a novel three-dimensional contingency table
 approach. Both assays reliably detected prior predation (e.g., at least
 one of the three sub-samples yielded a positive reaction) for 6 to 12 h
 after feeding. However, the generic ELISA was more reproducible (e.g., all
 three sub-samples yielded the same outcome) than the PCR. This shows that
 it was important to assay the predators in triplicate by PCR to avoid a
 high occurrence of false negative reactions. Conversely, reproducible
 results from the ELISA procedure were not dependent on duplicate
 sub-samples. Overall, the generic immunomarking gut assay procedure proved
 an effective method to assess predation.
