title: 16S rRNA V4 gut microbiome of Leptonycteris yerbabuenae in Mexico

description: Migratory animals live in a world of constant change. Animals undergo many
 physiological changes preparing themselves for the migration. Although
 this field has been extensively studied over the last decades, we know
 relatively little about the seasonal changes that occur in the microbial
 communities that these animals carry in their guts. Here we assessed the
 V4 region of the 16S rRNA high-throughput sequencing data as a proxy to
 estimate microbiome diversity of Tequila Bats from fecal pellets and
 evaluate how the natural process of migration shapes the microbiome
 composition, and diversity. We collected samples from individual bats at
 two localities in the Dry Forest biome (Chamela and Coquimatlán) and one
 site at the end point of the migration in the Sonoran Desert (Pinacate).
 We found that the gut microbiome of the Tequila bats is largely dominated
 by Firmicutes and Proteobacteria. Our data also provide insights on how
 microbiome diversity shifts at the same site in consecutive years. Our
 study has demonstrated that both locality and year-to-year variation
 contribute to shaping the composition, overall diversity, and the
 'uniqueness' of the gut microbiome of migratory nectar-feeding
 female bats with localities from the dry forest biome looking more like
 each other when compared to the desert biome. In terms of beta diversity,
 our data show a stratified effect in which the samples locality was the
 strongest factor influencing the gut microbiome, but with significant
 variation between consecutive years at the same locality.

title: Population dynamics of the sea snake Emydocephalus annulatus

description: For sea snakes as for many types of animals, long-term studies on
 population biology are rare and hence, we do not understand the degree to
 which annual variation in population sizes is driven by density-dependent
 regulation versus by stochastic abiotic factors. We monitored three
 populations of turtle-headed sea snakes (Emydocephalus annulatus) in New
 Caledonia over an 18-year period. Annual recruitment (% change in numbers)
 showed negative density-dependence: that is, recruitment increased when
 population densities were low, and decreased when densities were high.
 Windy weather during winter increased survival of neonates, perhaps by
 shielding them from predation; but those same weather conditions reduced
 body condition and the reproductive output of adult snakes. The role for
 density-dependence in annual dynamics of these populations is consistent
 with the slow, K-selected life-history attributes of the species; and the
 influence of weather conditions on reproductive output suggests that
 females adjust their allocation to reproduction based on food availability
 during vitellogenesis.

title: Data from: Equivalent learning, but unequal participation: male bumble bees learn comparably to females, but participate in cognitive assessments at lower rates

description: Sex-specific cognitive abilities are well documented. These can occur when
 sexes engage in different ecological contexts. Less known is whether
 different ecological contexts can also drive sex-specific participation
 rates in behavioral tests. Here, we explore this question in bumble bees,
 a group of eusocial insects where worker females and males exhibit stark
 socioecological differences. Among myriad colony maintenance tasks,
 workers forage for themselves and developing brood, while males forage
 only for themselves while mate-searching. Following upon previous studies
 suggesting no sex differences in bumble bee learning, we test the
 hypothesis that despite having equivalent associative learning abilities,
 males participate in cognitive assessments offering nutritional rewards at
 lower rates. Testing &gt;500 bees from nine colonies in a differential
 conditioning protocol, we find support for our hypothesis. An equivalent
 proportion of workers and males successfully completed our cognitive
 assessment, while a significantly lower proportion of males participated
 in the entire protocol. Unequal participation is a perennial issue in the
 behavioral sciences, limiting sample size and potentially biasing results.
 Our results suggest that to understand the true range of variation in
 cognition, sex-differences in participation must be accounted for.

title: Abundance of lungworm parasites in invasive cane toads from burned and unburned sites

description: The frequency and severity of wildfires are increasing due to
 anthropogenic modifications to habitats and to climate. Post-fire
 landscapes may advantage invasive species via multiple mechanisms,
 including changes to host-parasite interactions. We surveyed the incidence
 of endoparasitic lungworms (Rhabdias pseudosphaerocephala) in invasive
 cane toads (Rhinella marina) in near-coastal sites of eastern Australia, a
 year after extensive fires in this region. Both the prevalence of
 infection, and number of worms in infected toads, increased with toad body
 size in unburned areas. In contrast, parasite load decreased rather than
 increased with toad body size in burned areas. By killing
 moisture-dependent free-living lungworm larvae, the intense fires may have
 liberated adult cane toads from a parasite that can substantially reduce
 the viability of its host. Smaller toads, which are restricted to moist
 environments, did not receive this benefit from fires.
description: Toads were collected by community volunteers, humanely
 euthanased, and dissected to count lungworms.

title: Nonlinear time series analysis of the interaction between the citrus whitefly and the whitefly-specialist ladybird

description: A comprehensive understanding of the top-down effects of natural enemies
 on agricultural pests is essential for achieving effective biological
 control in integrated pest management. However, it is typically difficult
 to identify causal effects between the interacting species from time
 series data, which have often been monitored for pest forecasting purposes
 in agricultural ecosystems, as it is likely to involve nonlinear
 (state-dependent) population dynamics. In this study, we applied a
 recently developed framework of nonlinear time series analysis (empirical
 dynamic modeling) to determine top-down and bottom-up effects between the
 citrus whitefly Dialeurodes citri and the whitefly-specialist ladybird
 Serangium japonicum. We used weekly monitoring data for the two
 species collected over 4 years in pesticide-free citrus groves located in
 Shizuoka Prefecture, central Japan. Although we were able to identify
 time-delayed positive effects of D. citri abundance on S. japonicum
 abundance, we failed to detect any significant causal effects of S.
 japonicum abundance on D. citri abundance. Moreover, weather variables
 (temperature and rainfall) were found to have only a negligible effect on
 the population dynamics of the two species. Our findings indicate that
 bottom-up rather than top-down effects predominate in the weekly dynamics
 of this predator–prey system. On the basis of these observations, we
 discuss whether S. japonicum would be an effective agent for the
 biological control of D. citri in open field systems.

title: Data from: Axes of multivariate sexual signal divergence among incipient species: concordance with selection, genetic variation, and phenotypic plasticity

description: Sexual signaling traits are often observed to diverge rapidly among
 populations, thereby playing a potentially key early role in the evolution
 of reproductive isolation. While often assumed to reflect divergent sexual
 selection among populations, patterns of sexual trait diversification
 might sometimes be biased along axes of standing additive genetic
 variation and covariation among trait components. Additionally, theory
 predicts that environmentally-induced phenotypic variation might
 facilitate rapid trait evolution, suggesting that patterns of divergence
 between populations should mirror phenotypic plasticity within
 populations. Here we evaluate the concordance between observed axes of
 multivariate sexual trait divergence and predicted divergence based on (1)
 interpopulation variation in sexual selection, (2) additive genetic
 variances, and (3) temperature-related phenotypic plasticity in male
 courtship song among geographically isolated populations of the Hawaiian
 swordtail cricket, Laupala cerasina, which exhibit sexual isolation due
 sexual signaling traits. The major axis of multivariate divergence, dmax,
 accounted for 76% of variation among population male song trait means, and
 was moderately correlated with interpopulation differences in directional
 sexual selection based on female preferences. However, the majority of
 additive genetic variance was largely oriented away from the direction of
 divergence, suggesting that standing genetic variation may not play a
 dominant role in the patterning of signal divergence. In contrast, the
 axis of phenotypic plasticity strongly mirrored patterns of
 interpopulation phenotypic divergence, which is consistent with a role for
 temperature-related plasticity in facilitating instead of inhibiting male
 song evolution and sexual isolation in these incipient species. We propose
 potential mechanisms by which sexual selection might interact with
 phenotypic plasticity to facilitate the rapid acoustic diversification
 observed in this species and clade.

title: Data from: Early snowmelt by an extreme warm event affects understory more than overstory trees in Japanese temperate forests

description: We conducted a warming experiment (four 20 m by 20 m plots) in temperate
 forests of Japan to determine the effects of earlier snowmelt on both
 understory dwarf bamboo plants and overstory birch trees. Our experimental
 treatment advanced snowmelt by about 10 days and increased soil
 temperatures that were associated with increased rates of soil nitrogen
 (N) mineralization and nitrification. Furthermore, these changes led to
 lower C:N ratios of leaves together with the greater growth of understory
 bamboo vegetation, with no changes in leaf C:N or growth rates of
 overstory birch trees. Together, our results demonstrate that advancing
 snowmelt by an extreme warm event in temperate forests
 is likely to affect N cycling and will benefit understory vegetation
 without a commensurate change in overstory vegetation, likely due to the
 increase in available soil N. This is the dataset of plant
 growth, soil N properties, and plamnt leaf traits obtained by the field
 snowmelt manipulation experiment.

 experiment in cool-temperate forests of northern Japan.

title: Deer GPS and animal-borne camera data showing effects of gray wolves on niche overlap between mule and white-tailed deer in eastern Washington state

description: Predators may alter niche overlap between prey species by eliciting
 divergent anti-predator behavior. Accordingly, we exploited heterogeneous
 gray wolf (Canis lupus) presence in Washington, USA, to contrast patterns
 of resource and dietary overlap between mule (Odocoileus hemionus) and
 white-tailed deer (O. virginianus) at sites with and without resident
 packs. Mule deer run (stot) in a way that is less effective as a means of
 fleeing from predators than the galloping gait of white-tailed deer.
 Consequently, mule deer manage risk from coursing predators like wolves by
 avoiding encounters, whereas white-tailed deer respond to such predators
 by exploiting areas where they are most likely to escape pursuit. Thus,
 under the “refuge partitioning hypothesis” whereby predators reduce prey
 niche overlap by eliciting use of different refugia, we predicted wolf
 exposure to (i) decrease resource and dietary overlap between these
 ungulates, and (ii) induce segregation consistent with each species using
 different parts of the landscape to reduce their wolf risk. At the home
 range scale, the ways in which resource overlap diminished in the wolf
 areas were consistent with the prey species reducing their respective
 risks, particularly with respect to slope, with mule deer separating from
 white-tailed deer by seeking steeper areas where wolf encounters are less
 likely. At the within-home range scale, the manner in which spatial
 overlap decreased in relation to forest cover was consistent with
 species-specific risk management, with mule deer avoiding wolf encounters
 by shifting toward this resource. Reduced resource overlap between the
 deer in areas occupied by wolves did not correspond with dietary
 divergence. Our findings suggest that wolf risk mediates spatial but not
 necessarily dietary overlap between sympatric ungulates, divergent
 anti-predator behavior is a non-consumptive pathway by which predators can
 reduce interspecific competition among prey, and use of disparate refugia
 by prey may not result in dietary divergence.

 adult mule and white-tailed deer equipped with radio-collars (or
 cameras) in north-central Washington, USA, from 2013-2016. The GPS were
 used in this paper to quantify patterns of interspecific resource overlap
 between the two deer species, whereas the video data from the cameras were
 used to explore dietary overlap.

title: The effect of body size on co-occurrence patterns within an African carnivore guild

description: Intraguild interactions among mammalian carnivores are important in
 shaping carnivore guild composition. Competing species may inhabit
 different areas and/or being active during different times to reduce the
 risk of aggressive interactions, but the role of body size in intraguild
 interactions within carnivore guilds remains largely unknown. We
 determined spatial and temporal co-occurrence of small,
 medium-sized and large carnivores of the carnivore guild in central Tuli,
 Botswana: lion Panthera leo, leopard Panthera
 pardus, spotted hyena Crocuta crocuta, brown
 hyena Parahyaena brunnea, black-backed jackal Canis
 mesomelas, bat-eared fox Otocyon megalotis, African
 wildcat Felis sylvestris lybica, African
 civet Civettictis civetta, honey badger Mellivora
 capensis and small-spotted genet Genetta genetta. We
 used camera trap data over a 2-year period and quantified the degree of
 temporal and spatial overlap by comparing activity patterns and
 calculating Pianka’s index respectively. Our results showed that temporal
 overlap in activity between all carnivore species was high, but complete
 overlap was possibly reduced by differences in peak activity periods. In
 addition, low to moderate levels of spatial overlap were found between the
 different carnivore species, supporting the idea that small carnivore
 species inhabit different areas than large species to
 reduce the risk of interference competition. Due to the possible
 strong competition amongst sympatric carnivores there is a need for more
 knowledge on co-existence patterns for successful management and
 conservation of carnivore species, for example when carnivore species are
 (re)introduced in an area.

title: Strong genotype-by-genotype interactions between aphid-defensive symbionts and parasitoids persist across different biotic environments

description: The dynamics of coevolution between hosts and parasites are influenced by
 their genetic interactions. Highly specific interactions, where the
 outcome of an infection depends on the precise combination of host and
 parasite genotypes (G × G interactions), have the
 potential to maintain genetic variation by inducing negative
 frequency-dependent selection. The importance of this effect also rests on
 whether such interactions are consistent across different environments or
 modified by environmental variation
 (G × G × E interaction). In the black
 bean aphid, Aphis fabae, resistance to its
 parasitoid Lysiphlebus fabarum is largely determined by
 the possession of a heritable bacterial
 endosymbiont, Hamiltonella defensa, with strong
 G × G interactions
 between H. defensa and L. fabarum. A key environmental factor in this system is the host plant on which the aphid feeds. Here, we exposed genetically identical aphids harbouring three different strains of H. defensa to three asexual genotypes of L. fabarum and measured parasitism success on three common host plants of A. fabae, namely Vicia faba, Chenopodium album and Beta vulgaris. As expected, we observed the pervasive G × G interaction between H. defensa and L. fabarum, but despite strong main effects of the host plants on average rates of parasitism, this interaction was not altered significantly by the host plant environment (no G × G × E interaction). The symbiont-conferred specificity of resistance is thus likely to mediate the coevolution of A. fabae and L. fabarum, even when played out across diverse host plants of the aphid.

title: The multidimensional (and contrasting) effects of environmental warming on a group of montane tropical lizards: Lizard and plant data

description: 1. Mountains are cradles for biodiversity and crucibles for climate-driven
 species loss, particularly for tropical ectotherms. Constriction on
 activity and amplified heat stress are two key sources of warming-driven
 vulnerability in tropical montane ectotherms. These threats, however,
 might be counterbalanced if rising temperatures also release organisms
 from limits on activity induced by cold stress. 2. We used biophysical
 modeling to estimate activity patterns and thermal stress under warming in
 a group of summit-dwelling Anolis lizards (A. armouri and A. shrevei)
 endemic to the Caribbean island of Hispaniola. Activity is currently
 constrained by the prevalence of temperatures too cold for activity. Under
 warming, our models predict expanded hours of potential activity and
 reduced cold stress, especially under a high emission scenario. Crucially,
 release from cold stress does not come at the expense of heightened
 exposure to heat stress. This result arises from a steep mismatch between
 these species’ warm-adapted ecology and the surprisingly cold environments
 they occupy. 3. Yet, resilience in some dimensions belies vulnerability
 along others, particularly with regards to critical macrohabitat. We
 capitalized on a long-term monitoring dataset to predict forest
 distributions under warming. Our models predict upslope shifts in montane
 cloud forests that may constrict the high-elevation pine forests to which
 these lizards are inexorably linked. Warming-driven macrohabitat loss can
 ‘pin’ the montane endemics into progressively shrinking ranges, especially
 since a rising cloud forest also facilitates upslope transport of a close
 relative, A. cybotes (a species associated with broadleaf forests). 4.
 Many tropical ectotherms (including these anoles) are adapted to forest
 edges, a feature often associated with a relatively warm-adapted
 ecophysiology. When such species are also found in cool environments, such
 as those found on mountaintops, warming-amplified thermal stress is
 surprisingly limited. Therefore, the direct effects of warming on tropical
 ectotherms are quite broad, and can even include potential benefits to
 fitness-based activities. 5. Rising temperatures may often present a
 dual-edged sword: warming simultaneously releases these organisms from
 constraints on activity while exposing them to other threats. Whether due
 to the direct or indirect effects of climate warming, exceptional
 vulnerability may indeed reside where biodiversity is highest.

title: Louisiana mottled duck telemetry summer survival data 2018-2020 and water level data from Hurricane Laura surge

description: Tropical cyclones are the most powerful storms on earth, causing
 catastrophic damage to human lives and infrastructure. Hurricanes
 also cause wildlife mortality when they make landfall, but the severity of
 these effects is difficult to quantify because data collection is either
 logistically impossible or deprioritized in the wake of human
 tragedy. On 27 August 2020, Hurricane Laura made landfall in
 southwestern Louisiana with maximum sustained winds of 241 kph (150 mph),
 making it one of the most powerful storms to strike the mainland United
 States. Hurricane Laura passed directly over the core breeding
 range of the Western Gulf Coast population of Mottled Duck (Anas
 fulvigula), during a time when many adult birds were undergoing a
 simultaneous wing feather molt and were flightless. We used GPS-GSM
 telemetry data to evaluate survival rates of adult female Mottled Ducks in
 late summer 2020 (bracketing 27 August by one month on either side)
 relative to the same period in 2018 and 2019. Mortality was lower
 in 2018 (12 out of 29; 41%) and 2019 (8 out of 28; 29%) than in 2020 (12
 out of 18; 67%), and 7 out of 12 mortalities documented in 2020 occurred
 when Hurricane Laura made landfall. Survival analyses in Program
 MARK confirmed lower survival probability in 2020, but there was overlap
 in 85% confidence intervals in all years. This single storm
 resulted in the death of ~40% of all marked birds in our sample,
 suggesting that hurricanes have the potential to influence population
 demographics. In addition, Hurricane Laura resulted in widespread
 habitat loss and degradation that has reduced available nesting habitat in
 2021, and possibly for years to come. The acute and chronic
 effects of hurricanes may exacerbate Mottled Duck population declines,
 which may worsen in the face of increasingly frequent and more severe
 tropical storms.
