title: Data from: Novel sources of (co)variation in nestling begging behavior and hunger at different biological levels of analysis

description: Biological hypotheses predicting patterns of offspring begging typically
 concern the covariance with hunger and/or development at specific
 hierarchical levels. For example, hunger drives within-individual patterns
 of begging, but begging also drives food intake among individuals within
 broods, and begging and food intake can covary positively or negatively
 among genotypes or broods. Testing biological phenomena that occur at
 multiple levels therefore requires the partitioning of covariance between
 traits of interest to ensure that each level-specific relationship is
 appropriately assessed. We performed a partial cross-fostering study on a
 wild population of great tits (Parus major), then used multivariate
 mixed-models to partition variation and covariation in nestling begging
 effort and two metrics of nestling hunger within versus among individual
 nestlings and broods. At the within-individual level, we found that
 nestlings begged more intensely when hungrier (positive correlation
 between begging and hunger). However, among individuals, nestlings that
 were fed more frequently also begged more intensely on average (negative
 correlation between begging and hunger). Variation in nestling mass did
 not give rise to the negative correlation between begging and hunger among
 nestlings, but we did find that lighter nestlings begged more intensely
 than their heavier biological siblings, suggesting that this effect may be
 driven by a genetic component linked to offspring size. Our study
 illustrates how patterns of covariance can differ across biological levels
 of analysis and addresses biological mechanisms that could produce these
 previously obscured patterns.

title: Bayesian total-evidence inference resolves the position of the ant genus Phaulomyrma (Hymenoptera, Formicidae)

description: Although molecular data have proven indispensable in confidently resolving
 the phylogeny of many clades across the tree of life, these data may be
 inaccessible for certain taxa. The resolution of taxonomy in the ant
 subfamily Leptanillinae is made problematic by the absence of DNA sequence
 data for leptanilline taxa that are known only from male specimens,
 including the monotypic genus Phaulomyrma Wheeler & Wheeler.
 Focusing upon the considerable diversity of undescribed male leptanilline
 morphospecies, the phylogeny of 34 putative morphospecies sampled from
 across the Leptanillinae, plus an outgroup, is inferred from 11 nuclear
 loci and 41 discrete male morphological characters using a Bayesian
 total-evidence framework, with Phaulomyrma represented by morphological
 data only. Based upon the results of this analysis Phaulomyrma is
 synonymized with Leptanilla Emery, and male-based diagnoses for Leptanilla
 that are grounded in phylogeny are provided, under both broad and narrow
 circumscriptions of that genus. This demonstrates the potential utility of
 a total-evidence approach in inferring the phylogeny of rare extant taxa
 for which molecular data are unavailable and begins a long-overdue
 systematic revision of the Leptanillinae that is focused on male material.
description: Part of this dataset was derived from phylogenomic data obtained
 with the <em>hym-v2</em> ultra-conserved element probe set of
 Branstetter <em>et al.</em> (2017), with exons for 11 loci
 from <em>Leptanilla </em>GR02
 (ANT-exon-sequences-40-taxa-reduced.fasta) being used analogously to UCE
 probes in a modified <em>phyluce</em> workflow (Faircloth
 2016). For loci and taxa for which UCE enrichment was unsuccessful, the
 needed data were derived from a version of the 7,451-bp alignment of
 Borowiec <em>et al. </em>(2019), obtained via Sanger
 sequencing, that contains autapomorphic indels and introns (11,090
 bp). The concatenated alignment (9,351 bp) was then
 partitioned according to intronic/exonic nature and codon position, as was
 a 9,062-bp legacy-locus alignment was created that includes only those
 data published prior to this study (Ward & Sumnicht 2012; Borowiec
 <i>et al. </i>2019), with 20 terminals. These partitions were
 either used as an <em>ad hoc </em>partitioning scheme or input
 into PartitionFinder2 as character subsets.

title: Density dependence mediates the ecological impact of an invasive fish

description: Aim: The way in which habitat heterogeneity and predator density affect
 predator-prey dynamics, space use, and prey risk are understudied aspects
 of foraging ecology, particularly for invasive species. Likewise, how an
 invasive species’ impact scales with its abundance is poorly understood.
 We used a model invasive species, lionfish (Pterois volitans), to
 understand effects of multiple predators on consumption rate and prey
 mortality risk, foraging among multiple patches. Location Florida, USA
 Methods We considered effects of both predator and prey abundance on
 density-dependent impact. We used functional response methodology to
 quantify the per-capita effect of P. volitans, assessing concomitant
 influences of prey refuge (3 levels) and predator density (3 levels) on
 predator-prey space use and predation efficiency across increasing prey
 densities (7 levels). We then assessed intraspecific interaction outcomes
 by comparing observed per-capita effects with predicted estimates based on
 consumption rates of individual predators. This allowed us to detect the
 presence of emergent multiple predator effects (MPEs) and tease apart
 density-dependent impacts. Results Lionfish predatory impact was mediated
 by predator and prey density but unaffected by refugia. We detected
 non-linear scaling of impact with increasing predator abundance. Pairs of
 lionfish had the greatest per-capita effect, whose cumulative impact on
 prey matched that expected of independently foraging predators. At the
 highest predator density (four fish) antagonistic multiple predator
 effects precipitated prey risk reduction, in which we observed the lowest
 per-capita effect. Across predator abundance, prey mortality rates were
 inversely density-dependent. Despite incongruent patch preferences between
 predators and their prey, predator impacts were context-independent. Main
 conclusions Quantifying non-independent consumptive effects of multiple
 conspecific predators across levels of prey abundance can inform better
 prediction and understanding of invasive species' density-dependent
 effects. Additionally, consideration of heterogeneity-mediated FRs and
 predator-prey spatial distributions may facilitate more precise and
 realistic predictions of invader impact across their invaded range.

title: Seasonal changes in mixed-species bird flocks and anti-predator information

description: Animals acquire information produced by other species to reduce
 uncertainty and avoid predators. Mixed-species flocks (MSFs) of birds are
 ubiquitous in forest ecosystems and structured, in part, around
 interspecific information transfer, with ‘nuclear’ species providing
 information that other species eavesdrop on. We hypothesized that in a
 seasonal tropical forest, the amount of information produced by birds
 about predation would be dynamic, and particularly would decrease inside
 MSFs when the nuclear species leave MSFs to breed. We obtained baseline
 information on MSF encounter rate and species composition along
 established sampling routes over nine months near the Sino-Vietnamese
 border. We also conducted three experiments to quantify information
 produced by different species in response to typical predator encounters,
 including a moving predator stimulus presented inside of MSFs, and a
 stationary predator model presented both inside and outside of MSFs. MSFs
 were much less frequent in the breeding season with fewer individuals of
 the nuclear species, David’s Fulvetta (Alcippe davidi), participating,
 though the diversity of other species remained stable. Fulvettas were the
 dominant producer of alarm-related information both to the moving and
 stationary stimuli in MSFs, and were also among the most active mobbers to
 stimuli presented outside of MSFs. In the breeding season they tended to
 call less to the moving stimulus, and substantially fewer individuals
 responded to the in-flock stationary stimulus. Other species increased
 their own information production at stationary predator stimuli (inside
 and outside of MSFs) during the breeding season, perhaps due to their
 increased investment in offspring during this time. Yet even during the
 breeding season, David’s Fulvetta remained the highest producer of
 information about predators in MSFs. Hence, while we show that information
 production in MSFs can be somewhat dynamic, we describe a continually
 asymmetric communication system, in which a nuclear species is important
 to the whole community.

title: Social rank modulates how environmental quality influences cooperation and conflict within animal societies

description: Although dominance hierarchies occur in most societies, our understanding
 of how these power structures influence individual investment in
 cooperative and competitive behaviors remains elusive. Both conflict and
 cooperation in animal societies are often environmentally-regulated, yet
 how individuals alter their cooperative and competitive investments as
 environmental quality changes remains unclear. Using game theoretic
 modeling, we predict that individuals of all ranks will invest more in
 cooperation and less in social conflict in harsh environments than
 individuals of the same ranks in benign environments. Counterintuitively,
 low ranking subordinates should increase their investment in cooperation
 proportionally more than high ranking dominants, suggesting that
 subordinates contribute relatively more when facing environmental
 challenges. We then test and confirm these predictions experimentally
 using the Asian burying beetle Nicrophorus nepalensis. Ultimately, we
 demonstrate how social rank modulates the relationships between
 environmental quality and cooperative and competitive behaviours, a topic
 crucial for understanding the evolution of complex societies.

title: Historical translocations and stocking alter the genetic structure of a Mediterranean lobster fishery

description: Stocking is often used to supplement wild populations that are
 overexploited or have collapsed, yet it is unclear how this affects the
 genetic diversity of marine invertebrate populations. During the 1970s, a
 lobster stock enhancement programme was carried out around the island of
 Corsica in the Mediterranean using individuals translocated from the
 Atlantic coast of France. This included the release of thousands of
 hatchery-reared post-larval lobsters and several adult individuals, but no
 monitoring plan was established to assess whether these animals survived
 and recruited to the population. In this study, we sampled European
 lobster (Homarus gammarus) individuals caught around Corsica and tested
 whether they showed Atlantic ancestry. Due to a natural marked
 phylogeographic break between Atlantic and Mediterranean lobsters, we
 hypothesised that lobsters with dominant (&gt;0.50) Atlantic ancestry
 were descended from historical stocking releases. Twenty Corsican lobsters
 were genotyped at 79 single nucleotide polymorphisms and assignment
 analysis showed that the majority (13) had dominant Atlantic ancestry.
 This suggests that the hatchery stocking programme carried out in Corsica
 during the 1970s, using individuals translocated from the Atlantic coast
 of France, has likely augmented local recruitment but at a cost of
 altering the genetic structure of the Corsican lobster population.

title: Data from: Spatiotemporally precise optogenetic activation of sensory neurons in freely walking Drosophila

description: Previous work has characterized how walking Drosophila coordinate the
 movements of individual limbs (DeAngelis, Zavatone-Veth, and Clark, 2019).
 To understand the circuit basis of this coordination, one must
 characterize how sensory feedback from each limb affects walking behavior.
 However, it has remained difficult to manipulate neural activity in
 individual limbs of freely moving animals. Here, we demonstrate a simple
 method for optogenetic stimulation with body side-, body segment-, and
 limb-specificity that does not require real-time tracking. Instead, we
 activate at random, precise locations in time and space and use post hoc
 analysis to determine behavioral responses to specific activations. Using
 this method, we have characterized limb coordination and walking behavior
 in response to transient activation of mechanosensitive bristle neurons
 and sweet-sensing chemoreceptor neurons. Our findings reveal that
 activating these neurons has opposite effects on turning, and that
 activations in different limbs and body regions produce distinct
 behaviors.

title: Strong species differences in life-history do not predict oxidative stress physiology or sensitivity to an environmental oxidant

description: 1. Species typically align along a fast-slow life-history continuum, yet
 it is not clear to what extent oxidative stress physiology can be
 integrated with this continuum to form a ‘pace-of-life syndrome’,
 especially so in invertebrates. This is important, given the assumed role
 of oxidative stress in mediating life-history trade-offs, and the
 prediction that species with a faster pace should be more vulnerable to
 oxidative stress. 2. We tested whether a species’ life-history pace, here
 represented by its growth rate, can predict species-level differentiation
 in physiology and sensitivity to oxidative stress. Therefore, we exposed
 four species of Ischnura damselflies that strongly align along a fast-slow
 life-history continuum to different levels of ultraviolet (UV) radiation.
 We measured an extended set of physiological traits linked to the
 pace-of-life: standard metabolic rate (SMR), oxidative stress physiology
 (antioxidant enzymes and oxidative damage), and defence/condition traits
 (investment in immune function, energy storage, and structural defence).
 3. Despite strong species differences in growth rate and physiology,
 growth rate did not predict species-level differentiation in physiology.
 Hence there was no support for the integration of metabolic rate,
 oxidative stress physiology or defence/condition traits into a
 species-level syndrome. 4. UV exposure affected nearly all traits: it
 reduced growth rate and increased metabolic rate, affected all oxidative
 stress physiology traits and increased the two defence traits (immune
 function, and melanin content). Nevertheless, the pace-of-life based on
 growth rate did not predict sensitivity to UV. Instead, the observed
 pattern of investment in structural UV defence (melanin) might have
 reduced the need for enzymatic antioxidant defence, this way potentially
 decoupling the covariation between the life-history pace and oxidative
 stress physiology. 5. The absence of an integrated axis of life-history
 and physiological variation indicates no major constraints for the
 evolution of these traits among the studied damselfly species. Our study
 highlights that ecological differences between species may decouple
 covariation between species’ life-history pace and their physiology, as
 well as their sensitivity to environmental stressors. 30-Mar-2020

title: Data from: Geographic variation in adult and embryonic desiccation tolerance in a terrestrial-breeding frog

description: Intra-specific variation in the ability of individuals to tolerate
 environmental perturbations is often neglected when considering the
 impacts of climate change. Yet this information is potentially crucial for
 mitigating deleterious effects of climate change on threatened species.
 Here we assessed patterns of intra-specific variation in desiccation
 tolerance in the frog Pseudophryne guentheri, a terrestrial-breeding
 species experiencing a drying climate. Adult frogs were collected from six
 populations across a rainfall gradient and their dehydration and
 rehydration rates were assessed. We also compared desiccation tolerance of
 embryos and hatchlings originating from within-population parental crosses
 from four of the populations. Embryos were reared on soil at three
 soil-water potentials and their desiccation tolerance was assessed across
 a range of traits. We found significant and strong patterns of
 intra-specific variation in almost all traits, both in adults and
 first-generation offspring. Adult frogs exhibited clinal variation in
 their water balance responses, with populations from drier sites both
 dehydrating and rehydrating more slowly compared to frogs from more mesic
 sites. Similarly, desiccation tolerance of first-generation offspring was
 significantly greater in populations from xeric sites. Our findings
 suggest that populations within this species will respond differently to
 the regional reduction in rainfall predicted by climate change models.

title: Effects of nutrient limitation on the synthesis of N-rich phytoplankton toxins: a meta-analysis

description: Eutrophication has played a major role in the worldwide increase of
 harmful algal blooms (HABs). Higher input of key nutrients, such as
 nitrogen (N) and phosphorus (P), can stimulate the growth of harmful algal
 species in freshwater, estuarine, and coastal marine ecosystems. Some
 HAB-forming taxa, particularly several cyanobacteria and dinoflagellate
 species, are harmful through the production of N-rich toxins that have
 detrimental effects on the environment and human health. Here, we test how
 changes in nutrient availability affect N-rich toxin synthesis in
 cyanobacteria and dinoflagellates using a meta-analysis approach. Overall,
 N-rich toxin content showed an increase with P limitation, while it tended
 to decrease with N limitation, but we also observed substantial variation
 in responses both within and across genera and toxin groups. For instance,
 in response to N limitation, microcystin content varied from a 297%
 decrease up to a 273% increase, and paralytic shellfish poisoning (PSP)
 toxin content varied from a 204% decrease to an 82% increase.
 Cylindrospermopsin, produced by N2-fixing cyanobacteria, showed no clear
 direction in response to nutrient limitation, and cellular contents of
 this compound may thus vary independently of nutrient fluctuations. Our
 results confirm earlier reported stoichiometric regulation of N-rich
 phytoplankton toxins, showing increased toxin content with an increase in
 cellular N:P ratios, and vice versa. Thus, changes in N-rich toxin content
 largely follow the changes in relative cellular N content. Consequently,
 although nutrient limitation may limit bloom biomass and thereby bloom
 toxicity, our results warn that P limitation can cause accumulation of
 cellular toxins and thus lead to unexpected increases in bloom toxicity.

title: Biosynthesis, Characterization and Anti-dengue vector activity of Silver Nanoparticles prepared by Azadirachta indica and Citrullus colocynthis

description: Here, we report biosynthesis of silver nanoparticles (AgNPs) using aqueous
 extracts of (i) Azadirachta indica leaves and (ii) Citrullus colocynthis
 fruit and their larvicidal activity against Aedes aegypti. The Uv-Vis
 spectroscopy absorption peaks occurred in range 412-416 nm for A. indica
 AgNPs and 416-431nm for C. colocynthis AgNPs indicating the silver nature
 of prepared colloidal samples. The Scanning electron microscopy
 examination revealed the spherical morphology of both types of NPs with
 average size of 17±4 nm (A. indica AgNPs) and 26±5 nm (C. colocynthis
 AgNPs). The x-ray diffraction pattern confirmed the face centred cubic
 (FCC) structure with crystallite size of 11±1 nm (A. indica AgNPs) and
 15±1 nm (C. colocynthis AgNPs) while characteristic peaks appearing in
 Fourier transform infrared spectroscopy analysis indicated the attachment
 of different biomolecules on AgNPs.. The larvicidal activity at different
 concentrations of synthesized AgNPs (1-20 mg/L) and extracts (0.5 % - 1.5
 %) against Aedes aegypti was examined for 24 h. A concentration dependent
 larvicidal potential of both types of AgNPs was observed. The LC50 values
 were found to be 0.3 mg/L and 1.25 mg/L for C. colocynthis AgNPs and A.
 indica AgNPs respectively. However, extracts did not exhibit any notable
 larvicidal activity.
