title: Data from: Social and nutritional factors shape larval aggregation, foraging, and body mass in a polyphagous fly

description: The majority of insect species have a clearly defined larval stage during
 development. Larval nutrition is crucial for individuals’ growth and
 development, and larval foraging success often depends on both resource
 availability and competition for those resources. To date, however, little
 is known about how these factors interact to shape larval development and
 behaviour. Here we manipulated the density of larvae of the polyphagous
 fruit fly pest Bactrocera tryoni (‘Queensland fruit fly’), and the diet
 concentration of patches in a foraging arena to address this gap. Using
 advanced statistical methods of machine learning and linear regression
 models, we showed that high larval density results in overall high larval
 aggregation across all diets except in extreme diet dilutions. Larval
 aggregation was positively associated with larval body mass across all
 diet concentrations except in extreme diet dilutions where this
 relationship was reversed. Over time, larvae in low-density arenas also
 tended to aggregate while those in high-density arenas tended to disperse,
 an effect that was observed for all diet concentrations. Furthermore,
 larvae in high-density arenas displayed significant avoidance of low
 concentration diets – a behaviour that was not observed amongst larvae in
 low-density arenas. Thus, aggregation can help, rather than hinder, larval
 growth in high-density environments, and larvae may be better able to
 explore available nutrition when at high-density than when at low-density.

title: Data from: Combined observational and experimental data provide limited support for facilitation in lichens

description: It is increasingly recognized that facilitative interactions can shape
 communities. One of the mechanisms through which facilitation may operate
 is when one species facilitates the colonization of another through the
 exchange of shared symbionts. Lichens are symbiotic associations composed
 of a mycobiont (lichenised-fungus) and one or two photobionts (algae or
 cyanobacteria). Different lichen species may have overlapping specificity
 for photobionts, creating the possibility that facilitation drives lichen
 community assembly. To investigate whether facilitation occurs in lichens,
 we combined an observational study (a) with a manipulative field
 experiment (b). For (a), we quantified the effect of local patch
 conditions, facilitation and the size of the surrounding metapopulation on
 colonizations of an epixylic lichen species (Cladonia botrytes) in an area
 of managed boreal forest. This was done by twice surveying lichens on 293
 stumps, located in stands of three age classes. For (b), we treated
 unoccupied surfaces of 56 cut stumps with algal mixtures of an
 Asterochloris photobiont and recorded C. botrytes colonizations over three
 years. In (a), colonization rates of C. botrytes increased with increasing
 abundance of other lichen species with specificity for Asterochloris
 photobionts, consistent with an effect of facilitation. However, in the
 field experiment (b), colonizations of the focal species did not provide
 support for facilitation. We conclude that our study provides limited
 support for facilitation in green-algal lichens, underscoring the
 importance of combining observational studies with experiments when
 studying species interactions.

title: Data from: Developmental temperature affects the expression of ejaculatory traits and the outcome of sperm competition in Callosobruchus maculatus

description: The outcome of post-copulatory sexual selection is determined by a complex
 set of interactions between the primary reproductive traits of two or more
 males and their interactions with the reproductive traits of the female.
 Recently a number of studies have shown the primary reproductive traits of
 both males and females express phenotypic plasticity in response to the
 thermal environment experienced during ontogeny. However, how plasticity
 in these traits affects the dynamics of sperm competition remains largely
 unknown. Here we demonstrate plasticity in testes size, sperm size and
 sperm number in response to developmental temperature in the bruchid
 beetle Callosobruchus maculatus. Males reared at the highest temperature
 eclosed at the smallest body size and had the smallest absolute and
 relative testes size. Males reared at both the high and low temperature
 extremes produced both fewer and smaller sperm than males reared at
 intermediate temperatures. In the absence of sperm competition
 developmental temperature had no effect on male fertility. However, under
 conditions of sperm competition, males reared at either temperature
 extreme were less competitive in terms of sperm offence (P2), whilst those
 reared at the lowest temperature were less competitive in terms of sperm
 defence (P1). This suggests the developmental pathways that regulate the
 phenotypic expression of these ejaculatory traits are subject to both
 natural and sexual selection: natural selection in the pre-ejaculatory
 environment and sexual selection in the post-ejaculatory environment. In
 nature, thermal heterogeneity during development is commonplace.
 Therefore, we suggest the interplay between ecology and development
 represents an important, yet hitherto underestimated component of male
 fitness via post-copulatory sexual selection.

title: Data from: Mate competition and resource competition are inter-related in sexual selection

description: Sexual selection can be affected by the competition for limited breeding
 resources and/or the competition for limited mates. Although there is
 ample evidence for each type of competition by itself, little is known
 about their relative importance and interaction. To address these
 questions, we established 48 experimental breeding populations of the
 two-spotted goby (Gobiusculus flavescens), a substrate-breeding fish with
 paternal care. In three experimental treatments, males were limited in the
 access to either nest sites or mates or were provided with both nests and
 mates in excess. We quantified male competition behaviour (agonistic and
 courtship), the opportunity for selection and selection on male body size.
 Limited access to nests and mates produced similar opportunities for
 selection, but only limited access to mates increased male competitive
 behaviours and caused positive selection on male body size. Selection on
 body size in the mate-limited treatment was due both to larger males being
 more likely to take up nests and to larger males being more likely to mate
 once they had a nest. These findings demonstrate that resource and mate
 limitation can differ in their effects on sexual selection. The results
 also reveal that resource and mating competition can be highly
 inter-related and not always separated in time, implying that methods to
 disentangle the two processes must be chosen with care. Future research
 should consider experimental and analytical approaches similar to those of
 the present study in attempts to elucidate the interaction of resource and
 mating competition in animals.

title: Data from: Radiating despite a lack of character: ecological divergence among closely related, morphologically similar honeyeaters (Aves: Meliphagidae) co-occurring in arid Australian environments

description: Quantifying the relationship between form and function can inform use of
 morphology as a surrogate for ecology. How the strength of this
 relationship varies continentally can inform understanding of evolutionary
 radiations; for example, does the relationship break down when certain
 lineages invade and diversify in novel habitats? The 75 species of
 Australian honeyeaters (Meliphagidae) are morphologically and ecologically
 diverse, with species feeding on nectar, insects, fruit, and other
 resources. We investigated Meliphagidae ecomorphology and community
 structure by (1) quantifying the concordance between morphology and
 ecology (foraging behavior), (2) estimating rates of trait evolution in
 relation to the packing of ecological space, and (3) comparing
 phylogenetic and trait community structure across the broad environmental
 gradients of the continent. We found that morphology explained 37% of the
 variance in ecology (and 62% vice versa), and we uncovered well-known
 bivariate relationships among the multivariate ecomorphological data.
 Ecological trait diversity declined less rapidly than phylogenetic
 diversity along a gradient of decreasing precipitation. We employ a new
 method (trait fields) and extend another (phylogenetic fields) to show
 that while species in phylogenetically clustered, arid-environment
 assemblages are similar morphologically, they are as varied in foraging
 behavior as those from more diverse assemblages. Thus, although closely
 related and similar morphologically, these arid-adapted species have
 diverged in ecological space to a similar degree as their mesic
 counterparts.

title: Data from: Influence of interspecific competitors on behavioral thermoregulation: developmental or acute plasticity?

description: Many ectotherms reduce their exposure to changing thermal conditions using
 behavioral thermoregulation. The effectiveness of behavioral
 thermoregulation in maintaining ectotherm body temperatures within the
 target range is influenced not only by environmental (operative)
 temperatures but also by the presence of other con- and heterospecific
 individuals. How species’ interactions affect behavioral thermoregulation
 is largely unknown. Theory predicts that species’ interactions could
 affect the plasticity of behavioral thermoregulation in two ways, i.e. by
 developmental plasticity of a preferred temperature range or by an acute
 shift in body temperatures. Empirical tests of these predictions are
 scarce. We examined the developmental and acute effects of heterospecific
 social interactions on the accuracy and effectiveness of thermoregulation
 in larvae of two competing species, Ichthyosaura alpestris and Lissotriton
 vulgaris. The presence of heterospecifics during larval development had no
 effect on preferred body temperatures but it modified later acute
 thermoregulatory responses to heterospecifics. Ichthyosaura alpestris
 larvae from heterospecific tanks increased their thermoregulatory accuracy
 and effectiveness, while L. vulgaris larvae from conspecific tanks relaxed
 their thermoregulatory efforts. The thermal dependence of somatic growth
 suggests that modified behavioral thermoregulation has the potential to
 accelerate growth in competitively dominant I. alpestris. Acute
 thermoregulatory responses are affected by heterospecific social
 interactions in newt larvae, but not conspecific. A developmental plastic
 response modified body temperatures not the target thermoregulatory range,
 which shows that the influence of heterospecific social interactions is
 more complex than predicted by theory. Species interactions complicate
 estimating an ectotherm’s vulnerability to ongoing climate change.

title: Data from: Sexual conflict in action: an antagonistic relationship between maternal and paternal sex allocation in the tammar wallaby, Notamacropus eugenii

description: Sex ratio biases are often inconsistent, both among and within species and
 populations. While some of these inconsistencies may be due to
 experimental design, much of the variation remains inexplicable. Recent
 research suggests that an exclusive focus on mothers may account for some
 of the inconsistency, with an increasing number of studies showing
 variation in sperm sex ratios and seminal fluids. Using fluorescent
 in-situ hybridization we show a significant population level Y-chromosome
 bias in the spermatozoa of wild tammar wallabies, but with significant
 intra-individual variation between males. We also show a population-level
 birth sex ratio trend in the same direction towards male offspring, but a
 weaning sex ratio that is significantly female biased, indicating that
 males are disproportionately lost during lactation. We hypothesise that
 sexual conflict between parents may cause mothers to adjust offspring sex
 ratios after birth, through abandonment of male pouch young and
 reactivation of diapaused embryos. Further research is required in a
 captive, controlled setting to understand what is driving and
 mechanistically controlling sperm sex ratio and offspring sex ratio
 biases, and to understand the sexually antagonistic relationship between
 mothers and fathers over offspring sex. These results extend beyond sex
 allocation, as they question studies of population processes that assume
 equal input of sex chromosomes from fathers, and will also assist with
 future reproduction studies for management and conservation of marsupials.

title: Data from: Maternal effects are long lasting and influence female offspring’s reproductive strategy in the swordtail fish Xiphophorus multilineatus

description: The adaptive benefits of maternal investment into individual offspring
 (inherited environmental effects) will be shaped by selection on mothers
 as well as their offspring, often across variable environments. We
 examined how a mother’s nutritional environment interacted with her
 offspring’s nutritional and social environment in Xiphophorus
 multilineatus, a livebearing fish. Fry from mothers reared on two
 different nutritional diets (HQ = high quality, and LQ = low quality) were
 all reared on a LQ diet in addition to being split between two social
 treatments: exposed to a large adult male during development, and not
 exposed. Mothers raised on a HQ diet produce offspring that were not only
 initially larger (at 14 days of age), but grew faster, and were larger at
 sexual maturity, suggesting that the fry produced by mothers on LQ diets
 were at a disadvantage. Male offspring from mothers raised on both diets
 responded to the exposure to courter males by growing faster, however the
 response of their sisters varied with mother’s diet; Females from HQ
 mothers reduced growth if exposed to a courter male, while females from LQ
 mothers increased growth. Therefore, we detected variation in maternal
 investment depending on female size and diet, and the effects of this
 variation on offspring were long-lasting and sex specific. Our results
 support the maternal stress hypothesis, with selection on mothers to
 reduce investment in low quality environments that was not beneficial to
 the offspring. In addition, the interaction we detected between the
 mother’s nutritional environment and the female offspring’s social
 environment suggests that female offspring adopted different reproductive
 strategies depending on maternal investment.

title: Data from: Do soil biota influence the outcome of novel interactions between plant competitors?

description: 1. Species are shifting their ranges, for example to higher elevations, in
 response to climate change. Different plant species and soil microbiota
 will likely shift their ranges at different rates, giving rise to novel
 communities of plants and soil organisms. However, the ecological
 consequences of such novel plant-soil interactions are poorly understood.
 We experimentally simulated scenarios for novel interactions arising
 between high- and low elevation plants and soil biota following
 asynchronous climate change range shifts, asking to what extent the
 ability of plants to coexist depends on the origin of the soil biota. 2.
 In a greenhouse experiment, we grew pairs of low- (Poa trivialis and
 Plantago lanceolata) and high- (Poa alpina and Plantago alpina) elevation
 plant species alone and against a density gradient of con- or
 heterospecific neighbours. Plants grew on sterilized field soil that was
 inoculated with a soil community sampled from either low- or high
 elevation in the western Swiss Alps. We used the experiment to
 parameterize competition models, from which we predicted the
 population-level outcomes of competition in the presence of the different
 soil biota. 3. In the absence of neighbours, three of the four species
 produced more biomass with the low elevation soil biota. As a result of
 generally similar responses across plant species, soil biota tended not to
 affect plant interaction outcomes, with the low elevation species
 generally predicted to competitively exclude high elevation species
 irrespective of the soil biota origin. However, the low elevation grass
 Poa trivialis was only able to invade communities of Poa alpina in the
 presence of a low elevation soil biota. This suggests that, at least in
 some cases, the outcome of novel competitive interactions following
 climate change will depend on whether shifts in the distribution of plant
 and soil organisms are asynchronous. 4. Synthesis. Our results indicate
 that the changing soil communities that plants encounter during range
 expansion can influence plant performance. However, this is only likely to
 alter our expectations for the ability of plants to coexist following
 climate change if plant species respond differently to the change in the
 soil community.

description: Based on Landsat MSS/TM/OLI optical satellite remote sensing data from 1981 to 2020, visual interpretation was used to extract glacier and glacial lake boundaries in the Bugyai Kangri every ~5 years. Glacier area and length, as well as glacial lake area, were extracted at different times based on glacier/glacial lake boundaries. The vector layers of glacier and glacial lake boundaries are unified in the WGS1984 coordinate system and stored in ESRI Shape format; the attribute information such as glacier and glacial lake area is projected onto the UTM-Zone_46N coordinate system, and stored in MS Excel format. The area error of glaciers and glacial lakes was estimated using the pixel buffer method. Based on the 1980 Chinese historical topographic map, the 2000 SRTM DEM, and the 2014 and 2020 TanDEM data, the changes in glacier mass in Bugyai Kangri were calculated using geodetic methods. Before extracting changes in glacier mass, different DEM data were unified to a spatial resolution of 30 m and coordinate system UTM-Zone_46N, and spatial matching errors were corrected based on terrain factors. SRTM X-band data was used to exclude the influence of C-band radar snow penetration on the data results. Finally, the accuracy of glacier mass change was evaluated using the mean square error in glacier-free areas.
