title: Data from: Size-mediated priority and temperature effects on intra-cohort competition and cannibalism in a damselfly

description: 1. A shift in the relative arrival of offspring, e.g., a shift in hatching
 time, can affect competition at the intraspecific level through
 size-mediated priority effects, where the larger individuals gain more
 resources. These priority effects are likely to be affected by climate
 warming and the rate of intraspecific predation, i.e., cannibalism. 2. In
 a laboratory experiment, we examined size-mediated priority effects in
 larvae of the univoltine damselfly, Lestes sponsa, at two different
 temperatures (21°C and 23°C). We created three size groups of larvae by
 manipulating hatching time: early hatched with a large size
 (extra-advanced), intermediate hatched with an intermediate size
 (advanced) and late hatched with a small size (non-advanced). Thereafter
 we reared the larvae from these groups in non-mixed and mixed groups of 12
 larvae. 3. We found strong priority and temperature effects. First,
 extra-advanced larvae most often had higher survival, growth and
 development rates than non-advanced larvae in mixed groups, compared to
 groups that consisted of only extra-advanced larvae. Second, temperature
 increased growth and development rates and cannibalism. 4. However, the
 strength of priority effects did not differ between the two experimental
 temperatures, because there was no statistical interaction between
 temperature and treatments. That is, the mixed and non-mixed groups of
 non-advanced, advanced and extra-advanced larvae showed the same relative
 change in life history traits across the two temperatures. 5. Non-advanced
 and advanced larvae had similar or higher growth rate and mass in mixed
 groups compared to non-mixed groups, suggesting that predation from
 advanced larvae in the mixed group released resources for the non-advanced
 and advanced larvae that survived despite cannibalism risk. Thus, a
 thinning effect occurred due to cannibalism caused by priority effects. 6.
 The results suggest that a shift in the relative arrival of offspring can
 cause temperature-dependent priority effects, mediated through
 cannibalism, growth and development, which may change the size
 distribution and abundance of emerging aquatic insects.

title: Data from: Population variation, environmental gradients, and the evolutionary ecology of plant defense against herbivory

description: A central tenet of plant defense theory is that adaptation to the abiotic
 environment sets the template for defense strategies, imposing a tradeoff
 between plant growth and defense. Yet, this tradeoff, commonly found among
 species occupying divergent resource environments, may not occur across
 populations of single species. We hypothesized that more favorable
 climates and higher levels of herbivory would lead to increases in growth
 and defense across plant populations. We evaluated whether plant growth
 and defense traits co-varied across 18 populations of showy milkweed
 (Asclepias speciosa) inhabiting an east-west climate gradient, spanning
 25° of longitude. A suite of traits impacting defense (e.g., latex,
 cardenolides), growth (e.g., size), or both (e.g., SLA, trichomes) were
 measured in natural populations and in a common garden, allowing us to
 evaluate plastic and genetically based variation in these traits. In
 natural populations, herbivore pressure increased towards warmer sites
 with longer growing seasons. Growth and defense traits showed strong
 clinal patterns and were positively correlated. In a common garden, clines
 with climatic origin were only recapitulated for defense traits.
 Correlations between growth and defense traits were also weaker and more
 negative in the common garden compared to the natural populations. Thus,
 our data suggest that climatically favorable sites likely facilitate the
 evolution of greater defense at minimal costs to growth, likely because of
 increased resource acquisition.

title: Data from: Population biology of establishment in New Zealand hedgehogs inferred from genetic and historical data: conflict or compromise?

description: The crucial steps in biological invasions, related to the shaping of
 genetic architecture and the current evolution of adaptations to a novel
 environment, usually occur in small populations during the phases of
 introduction and establishment. However, these processes are difficult to
 track in nature due to invasion lag, large geographic and temporal scales
 compared with human observation capabilities, the frequent depletion of
 genetic variance, admixture and other phenomena. In this study, we
 compared genetic and historical evidence related to the invasion of the
 West European hedgehog to New Zealand to infer details about the
 introduction and establishment. Historical information indicates that the
 species was initially established on the South Island. A molecular assay
 of populations from Great Britain and New Zealand using mitochondrial
 sequences and nuclear microsatellite loci was performed based on a set of
 analyses including approximate Bayesian computation, a powerful approach
 for disentangling complex population demographies. According to these
 analyses, the population of the North Island was most similar to that of
 the native area and showed greatest reduction in genetic variation caused
 by founder demography and/or drift. This evidence indicated the location
 of the establishment phase. The hypothesis was corroborated by data on
 climate and urbanization. We discuss the contrasting results obtained by
 the molecular and historical approaches in the light of their different
 explanatory power and the possible biases influencing the description of
 particular aspects of invasions, and we advocate the integration of the
 two types of approaches in invasion biology.

title: Data from: A generalist brood parasite modifies use of a host in response to reproductive success

description: Avian obligate brood parasites, which rely solely on hosts to raise their
 young, should choose the highest quality hosts to maximize reproductive
 output. Brown-headed cowbirds (Molothrus ater) are extreme host
 generalists, yet female cowbirds could use information based on past
 reproductive outcomes to make egg-laying decisions thus minimizing fitness
 costs associated with parasitizing low-quality hosts. We use a long-term
 (21 years) nest-box study of a single host, the prothonotary warbler
 (Protonotaria citrea), to show that local cowbird reproductive success,
 but not host reproductive success, was positively correlated with the
 probability of parasitism the following year. Experimental manipulations
 of cowbird success corroborated that female cowbirds make future decisions
 about which hosts to use based on information pertaining to past cowbird
 success, both within and between years. The within-year pattern, in
 particular, points to local cowbird females selecting hosts based on past
 reproductive outcomes. This, coupled with high site fidelity of female
 cowbirds between years, points to information use, rather than cowbird
 natal returns alone, increasing parasitism rates on highly productive
 sites between years.

title: Data from: Humidity levels drive reproductive modes and phylogenetic diversity of amphibians in the Brazilian Atlantic Forest

description: AIM: The diversity of reproductive modes among amphibians provides a
 striking example of how differences in the biology of species furnish can
 provide important explanations for species distribution patterns on a
 broad scale. We hypothesized that sites with a higher humidity level will
 support more different modes of reproduction than drier sites and will
 consequently exhibit a higher phylogenetic diversity. Furthermore, we
 predict that if there is a gradient in the tolerance of reproductive modes
 to desiccation, there will be a nested pattern in the composition of
 reproductive modes among sites. LOCATION: Twenty-seven forest sites in the
 Brazilian Atlantic Forest. METHODS: Through a path analysis approach, we
 evaluated the direct and indirect effects of the humidity level on the
 number of reproductive modes as well as the relative importance of both
 variables on amphibian phylogenetic diversity. A nestedness analysis was
 used to quantify the extent to which the composition of both species and
 reproductive modes in drier sites correspond to non-random subsets of
 those in sites with higher annual precipitation. RESULTS: We found that
 the reproductive modes present in drier sites are non-random subsets of
 those present in sites with higher humidity levels. Because reproductive
 modes are phylogenetically conserved among amphibians, sites with a
 greater number of reproductive modes supported greater phylogenetic
 diversity. Sites with high precipitation throughout the year provided
 adequate environmental conditions for a larger number of reproductive
 modes, whereas sites with low precipitation and typical seasonal climates
 supported only those reproductive modes specialized to resist desiccation.
 MAIN CONCLUSIONS: Our results show that humidity-related variables are key
 environmental factors related to both the richness of reproductive modes
 and phylogenetic diversity. We hypothesized that the higher phylogenetic
 diversity found in moister sites reflects differences in the tolerance to
 desiccation among different reproductive modes. Given that reproductive
 modes are associated with susceptibility to desiccation, their
 incorporation into explanatory models may trigger a great advance in the
 understanding of the mechanisms regulating the species richness and
 composition of amphibian communities.

title: Data from: Shifts and disruptions in resource-use trait syndromes during the evolution of herbaceous crops

description: Trait-based ecology predicts that evolution in high-resource agricultural
 environments should select for suites of traits that enable fast resource
 acquisition and rapid canopy closure. However, crop breeding targets
 specific agronomic attributes rather than broad trait syndromes. Breeding
 for specific traits, together with evolution in high-resource
 environments, might lead to reduced phenotypic integration, according to
 predictions from the ecological literature. We provide the first
 comprehensive test of these hypotheses, based on a trait-screening
 programme of 30 herbaceous crops and their wild progenitors. During crop
 evolution plants became larger, which enabled them to compete more
 effectively for light, but they had poorly integrated phenotypes. In a
 subset of six herbaceous crop species investigated in greater depth,
 competitiveness for light increased during early plant domestication,
 whereas diminished phenotypic integration occurred later during crop
 improvement. Mass-specific leaf and root traits relevant to resource-use
 strategies (e.g. specific leaf area or tissue density of fine roots)
 changed during crop evolution, but in diverse and contrasting directions
 and magnitudes, depending on the crop species. Reductions in phenotypic
 integration and overinvestment in traits involved in competition for light
 may affect the chances of upgrading modern herbaceous crops to face
 current climatic and food security challenges.

title: Data from: Major histocompatability complex variation in insular populations of the Egyptian vulture: inferences about the roles of genetic drift and selection

description: Insular populations have attracted the attention of evolutionary
 biologists because of their morphological and ecological peculiarities
 with respect to their mainland counterparts. Founder effects and genetic
 drift are known to distribute neutral genetic variability in these demes.
 However, elucidating whether these evolutionary forces have also shaped
 adaptive variation is crucial to evaluate the real impact of reduced
 genetic variation in small populations. Genes of the Major
 Histocompatibility Complex (MHC) are classical examples of evolutionarily
 relevant loci because of their well-known role in pathogen confrontation
 and clearance. In this study, we aim to disentangle the partial roles of
 genetic drift and natural selection in the spatial distribution of MHC
 variation in insular populations. To this end, we integrate the study of
 neutral (22 microsatellites and one mtDNA locus) and MHC class II
 variation in one mainland (Iberia) and two insular populations
 (Fuerteventura and Menorca) of the endangered Egyptian vulture (Neophron
 percnopterus). Overall, the distribution of the frequencies of individual
 MHC alleles (N=17 alleles from two class II B loci) does not significantly
 depart from neutral expectations, which indicates a prominent role for
 genetic drift over selection. However, our results point towards an
 interesting co-evolution of gene duplicates that maintains different pairs
 of divergent alleles in strong linkage disequilibrium on islands. We
 hypothesize that the co-evolution of genes may counteract the loss of
 genetic diversity in insular demes, maximize antigen recognition
 capabilities when gene diversity is reduced, and promote the
 co-segregation of the most efficient allele combinations to cope with
 local pathogen communities.

title: Data from: Challenging the inbreeding hypothesis in a eusocial mammal: population genetics of the naked mole-rat, Heterocephalus glaber.

description: The role of genetic relatedness in the evolution of eusociality has been
 the topic of much debate, especially when contrasting eusocial insects
 with vertebrates displaying reproductive altruism. The naked mole-rat,
 Heterocephalus glaber, was the first described eusocial mammal. Although
 this discovery was based on an ecological constraints model of eusocial
 evolution, early genetic studies reported high levels of relatedness in
 naked mole-rats, providing a compelling argument that low dispersal rates
 and consanguineous mating (inbreeding as a mating system) are the driving
 forces for the evolution of this eusocial species. One caveat to accepting
 this long-held view is that the original genetic studies were based on
 limited sampling from the species’ geographic distribution. A growing body
 of evidence supports a contrary view, with the original samples not
 representative of the species—rather reflecting a single founder event,
 establishing a small population south of the Athi River. Our study is the
 first to address these competing hypotheses by examining patterns of
 molecular variation in colonies sampled from north and south of the Athi
 and Tana rivers, which based on our results, serve to isolate genetically
 distinct populations of naked mole-rats. Although colonies south of the
 Athi River share a single mtDNA haplotype and are fixed at most
 microsatellite loci, populations north of the Athi River are considerably
 more variable. Our findings support the position that the low variation
 observed in naked mole-rat populations south of the Athi River reflects a
 founder event, rather than a consequence of this species’ unusual mating
 system.

title: Data from: Interspecific aggression, not interspecific mating, drives character displacement in the wing colouration of male rubyspot damselflies (Hetaerina)

description: Traits that mediate intraspecific social interactions may overlap in
 closely related sympatric species, resulting in costly between-species
 interactions. Such interactions have principally interested investigators
 studying the evolution of reproductive isolation via reproductive
 character displacement (RCD) or reinforcement, yet in addition to
 reproductive interference, interspecific trait overlap can lead to costly
 between-species aggression. Previous research on rubyspot damselflies
 (Hetaerina spp.) demonstrated that sympatric shifts in male wing colour
 patterns and competitor recognition reduce interspecific aggression,
 supporting the hypothesis that agonistic character displacement (ACD)
 drove trait shifts. However, a recent theoretical model shows that RCD
 overshadows ACD if the same male trait is used for both female mate
 recognition and male competitor recognition. To determine whether female
 mate recognition is based on male wing coloration in Hetaerina, we
 conducted a phenotype manipulation experiment. Compared to control males,
 male H. americana with wings manipulated to resemble a sympatric congener
 (H. titia) suffered no reduction in mating success. Thus, female mate
 recognition is not based on species differences in male wing coloration.
 Experimental males did, however, experience higher interspecific fighting
 rates and reduced survival compared to controls. These results greatly
 strengthen the case for ACD and highlight the mechanistic distinction
 between ACD and RCD.

title: Data from: Translocation strategies for multiple species depend on interspecific interaction type

description: Conservation translocations – anthropogenic movements of species to
 prevent their extinction – have increased substantially over the last few
 decades. Although multiple species are frequently moved to the same
 location, current translocation guidelines consider species in isolation.
 This practice ignores important interspecific interactions, and thereby
 risks translocation failure. We model three different two-species systems
 to illustrate the inherent complexity of multi-species translocations, and
 to assess the influence of different interaction types (consumer-resource,
 mutualism, and competition) on translocation strategies. We focus on how
 these different interaction types influence the optimal founder population
 sizes for successful translocations, and the order in which the species
 are moved (simultaneous or sequential). Further, we assess the effect of
 interaction strength in simultaneous translocations, and the time delay
 between translocations when moving two species sequentially. Our results
 show that translocation decisions need to reflect the type of interaction.
 While all translocations of interacting species require a minimum founder
 population size, which is demarked by an “extinction boundary”,
 consumer-resource translocations also have a maximum founder population
 limit. Above the minimum founder size, increasing the number of
 translocated individuals leads to a substantial increase in the extinction
 boundary of competitors and consumers, but not of mutualists. Competitive
 and consumer-resource systems benefit from sequential translocations; but
 the order of translocations does not change the outcomes for mutualistic
 interaction partners noticeably. Interspecific interactions are important
 processes that shape population dynamics, and should therefore be
 incorporated into the quantitative planning of multispecies
 translocations. Our findings apply whenever interacting species are moved,
 for example, in reintroductions, conservation introductions, biological
 control or ecosystem restoration.
