title: Data from: Incipient radiation within the dominant Hawaiian tree Metrosideros polymorpha

description: Although trees comprise a primary component of terrestrial species
 richness, the drivers and temporal scale of divergence in trees remain
 poorly understood. We examined the landscape-dominant tree, Metrosideros
 polymorpha, for variation at nine microsatellite loci across 23
 populations on young Hawai’i Island, sampling each of the island’s five
 varieties throughout its full geographic range. For four varieties,
 principal coordinate analysis revealed strong clustering of populations by
 variety across the 10 430 km island, indicating partitioning of the
 species into multiple evolutionarily significant units. The single
 island-endemic form, riparian var. newellii, showed especially strong
 differentiation from other varieties despite occurring in sympatry with
 other varieties and likely evolved from a bog form on the oldest volcano,
 Kohala, within the past 500 000 years. Along with comparable riparian
 forms on other Pacific Islands, var. newellii appears to represent
 parallel incipient ecological speciation within Metrosideros. Greater
 genetic distance among the more common varieties on the oldest volcano and
 an inverse relationship between allelic diversity and substrate age appear
 consistent with colonization of Hawai’i Island by older, partially
 diverged varieties followed by increased hybridization among varieties on
 younger volcanoes. This study demonstrates that broad population-level
 sampling is required to uncover patterns of diversification within a
 ubiquitous and long-lived tree species. Hawaiian Metrosideros appears to
 be a case of incipient radiation in trees and thus should be useful for
 studies of divergence and the evolution of reproductive isolating barriers
 at the early stages of speciation.

title: Data from: Parasitoid wasps influence where aphids die via an inter-specific indirect genetic effect

description: Host–parasite interactions are a key paradigm for understanding the
 process of coevolution. Central to coevolution is how genetic variation in
 interacting species allows parasites to evolve manipulative strategies.
 However, genetic variation in the parasite may also be associated with
 host phenotype changes, thereby changing the selection on both species.
 For instance, parasites often induce changes in the behaviour of their
 host to maximize their own fitness, yet the quantitative genetic basis for
 behavioural manipulation has not been fully demonstrated. Here, we show
 that the genotype of the parasitoid wasp Aphidius ervi has a significant
 effect on where its aphid host Acyrthosiphon pisum moves to die following
 parasitism, including the likelihood that the aphid abandons the plant.
 These results provide a clear example of an interspecific indirect genetic
 effect whereby the genetics of one species influences the expression of a
 specific behavioural trait in another.

title: Data from: Sleeping with the ‘enemy’ - Hybridization of an endangered tree weta

description: While hybridization is an important part of the evolutionary process, for
 rare species mating with more common species hybridization can increase
 the risks of extinction. By mating with heterospecifics rare species waste
 valuable reproductive resources and as a result population sizes may
 decline. If introgression occurs, the rare species can become genetically
 swamped by alleles from the more common species, rendering it effectively
 extinct. As a consequence of these risks, hybridization with the more
 common species Hemideina femorata (Canterbury tree weta) may lead to the
 extinction of the range restricted species H. ricta (Banks Peninsula tree
 weta) on Banks Peninsula. The current study uses spatial interpolation to
 model the distribution of each species and the potential sympatric zone to
 guide sampling efforts. Polymorphic microsatellite markers and
 mitochondrial sequence data were used to determine the extent of
 hybridization between H. ricta and H. femorata. The results confirm that
 hybridization is possible between these species. However, hybrids and
 introgression appear to be very rare, suggesting that reproductive
 isolating barriers are present but incomplete. The threat of extinction to
 H. ricta via hybridization with H. femorata is low but extreme loss of
 habitat may cause changes to population densities that could increase the
 risks of hybridization. Therefore, landowners should be encouraged to
 conserve native bush.

title: Data from: Aging alters interspecific competition between two sympatric insect-parasitic nematode species

description: Interspecific competition can vary depending on the stage, age, or
 physiological state of the competitors. Competitive ability often
 increases with age or size; alternatively, senescence can lead to a loss
 of viability and reduced competitive success. Differences between species
 in their age-specific competitive abilities can promote coexistence in the
 face of substantial niche overlap. We examined two sympatric species of
 nematodes (genus Steinernema) to determine whether their competitive
 relationship changes as a function of age. These obligately killing insect
 parasites are known for their broad host ranges and are transmitted from
 insect to insect via a juvenile stage propagule that is free-living in the
 soil. Here, we tested whether the two species differed in the effects of
 age by examining the mortality of insect hosts infected with young or old
 transmission stage nematodes of each species. We also performed mixed
 infections, where an equal ratio of both species was simultaneously
 exposed to a host, to determine the effect of age on competitiveness. One
 species showed reduced performance with age, as older propagules were
 slower at inducing host mortality. In contrast, the other species
 increased in killing speed with age. In competition, insect mortality rate
 was predictive of competitive outcome, such that if one species induced
 considerably faster host death in a single-species infection, it was
 competitively dominant in the coinfection. Accordingly, we found a shift
 in the competitive relationship between the two species with age. Our work
 demonstrates that species differences in the effects of aging can lead to
 dramatic shifts in reproductive success. As these effects are realized
 solely in a competitive environment, both spatial patchiness and temporal
 niche partitioning may be important for promoting coexistence.

title: Data from: Cascading effects of thermally-induced anemone bleaching on associated anemonefish hormonal stress response and reproduction

description: Organisms can behaviorally, physiologically, and morphologically adjust to
 environmental variation via integrative hormonal mechanisms, ultimately
 allowing animals to cope with environmental change. The stress response to
 environmental and social changes commonly promotes survival at the expense
 of reproduction. However, despite climate change impacts on population
 declines and diversity loss, few studies have attributed hormonal stress
 responses, or their regulatory effects, to climate change in the wild.
 Here, we report hormonal and fitness responses of individual wild fish to
 a recent large-scale sea warming event that caused widespread bleaching on
 coral reefs. This 14-month monitoring study shows a strong correlation
 between anemone bleaching (zooxanthellae loss), anemonefish stress
 response, and reproductive hormones that decreased fecundity by 73%. These
 findings suggest that hormone stress responses play a crucial role in
 changes to population demography following climate change and plasticity
 in hormonal responsiveness may be a key mechanism enabling individual
 acclimation to climate change.

title: Data from: Polyandry and the decrease of a selfish genetic element in a wild house mouse population

description: Despite deleterious effects on individuals, the t haplotype is a selfish
 genetic element present in many house mouse populations. By distorting the
 transmission ratio, +/t males transmit the t haplotype to up to 90% of
 their offspring. However, t/t individuals perish in utero. Theoretical
 models based on these properties predict a much higher t frequency than
 observed, leading to the t paradox. Here, we use empirical field data and
 theoretical approaches to investigate whether polyandry is a female
 counterstrategy against the negative fitness consequences of such
 distorters. We found a significant decrease of the t frequency over a
 period of 5.5 years that cannot be explained by the effect of transmission
 ratio distortion and recessive lethals, despite significantly higher life
 expectancy of +/t females compared to +/+ females. We quantified life
 history data and homozygous and heterozygous fitness effects. Population
 subdivision and inbreeding were excluded as evolutionary force influencing
 the t system. The possible influence of polyandry on the t system was then
 investigated by applying a stochastic model to this situation. Simulations
 show that polyandry can explain the observed t dynamics, making it a
 biologically plausible explanation for low t frequencies in natural
 populations in general.

title: Data from: Genetic divergence for physiological response to temperature between populations of a C3-C4 intermediate annual

description: Premise of research. Local adaptation ultimately arises as a result of
 adaptive divergence in phenotypic characters. Within a species, a large
 portion of the phenotypic traits that confer local adaptation must be
 physiological characters. Yet few studies consider adaptive divergence in
 physiological characters or estimate genetic variation within populations
 for physiological traits that may confer local adaptation. Here I test the
 hypothesis that there is genetic variation within and between populations
 of a C3-C4 intermediate for the CO2 compensation point (Γ) and other
 photosynthetic traits. In addition to local adaptation, population-level
 variation in photosynthetic characters of C3-C4 intermediates reflects the
 potential for evolution of more C4-like photosynthesis. Methodology. I
 chose two populations of Mollugo verticillata, one from a relatively cool
 climate and one from a warm climate. I quantified variation within and
 between populations by measuring photosynthetic physiology at 24° and
 35°C, temperatures that match the average maximums during the growing
 season at the populations’ native sites. Pivotal results. I detected
 little evidence of genetic variation within populations for Γ and
 carboxylation efficiency, but there was temperature-dependent population
 variation for Γ, where the population from the cool climate had a lower
 average Γ at 24°C. Apparent chlorophyll concentration was also greater in
 this population at both temperatures. Conclusions. The results demonstrate
 that there has been divergence among populations in Γ. Interestingly, the
 population from the cooler climate had lower Γ at 24°C. There is little
 evidence of adaptive evolutionary potential within populations; estimates
 of broad-sense heritability were not significant even when pooling samples
 from both populations to increase the overall sample size. Adaptation of
 more C4-like photosynthesis may proceed through the evolution of other
 physiological characters not directly related to concentrating carbon.

title: Data from: Plant nitrogen and phosphorus utilization under invasive pressure in a montane ecosystem of tropical China

description: 1. Exotic plant invasion has been changing the vegetation composition and
 function of terrestrial ecosystems. Nitrogen (N) and phosphorus (P) are
 often the limiting nutrients for terrestrial plants. However, under
 invasive pressure, in-situ plant N and P use mechanisms remain poorly
 understood but is pivotal for a better understanding of plant invasion and
 coexistence in invaded ecosystems. 2. Nitrogen and P concentrations,
 natural 15N abundance (δ15N values) were investigated in leaves and soils
 under different invasive pressures (here expressed as the biomass
 percentages of invasive plants in each plot) for two invasive species
 (Chromolaena odorata and Ageratina adenophora) in Xishuangbanna in
 tropical China. 3. Soil N and P concentrations revealed the relatively
 N-rich but P-poor status of our study site. Under invasion, soil inorganic
 N (dominated by ammonium) and available P increased. The leaf N and P of
 invasive plants also increased, while leaf N increased but P decreased for
 native species. Natural δ15N mass balance between leaves and soil
 inorganic N sources revealed that ammonium dominated N utilization in both
 natives and invaders. Invasive plants showed ammonium preference with
 increasing leaf N levels, while native plants under no invasion showed
 nitrate preference with increasing leaf N levels. 4. Synthesis. Increased
 soil ammonium availability contributed to preferential ammonium
 utilization by invasive plants and elevated ammonium utilization in
 natives, but the P competition of natives decreased in invaded ecosystems.
 These novel insights into nutrients dynamics in invaded ecosystems enhance
 our understanding of plant invasion and coexistence mechanisms.

title: Data from: Occurrence of canine parvovirus in dogs from Henan province of China in 2009–2014

description: Background There is no information concerning the genotype of Canine
 parvovirus (CPV) currently circulating in Henan province, China.
 Therefore, the aim of the present study was to provide insights into the
 epidemiology and molecular characterization of CPV circulating in Henan
 province from 2009 to 2014. Results Nineteen thousand nine hundred seven
 dogs from pet hospitals in the cities of Luoyang, Anyang, Jiaozuo,
 Sanmenxia, Xinxiang, Zhengzhou in Henan province between 2009 and 2014
 were investigated. Over the 6-year period, 1169 CPV-positive cases were
 identified and the morbidity of CPV infection ranged from 4.16 to 8.06 %,
 although morbidity was not significant (P &gt; 0.05) between 2009 and
 2014. Factors associated with morbidity included sampling season, dog age,
 breed, vaccination status, and sex. CPV co-infection with coccidium (10.00
 %), canine distemper virus (4.79 %), hookworm (2.40 %), canine coronavirus
 (1.11 %), roundworm (1.03 %), tapeworm (0.17 %) and Babesia spp. (0.09 %)
 were observed. The new CPV-2a variant was more prevalent than the new
 CPV-2b variant in Henan province. CPV 2c was not observed in this study.
 Conclusions The epidemiology of CPV infection and identification of the
 circulating genotypes in Henan province, China from 2009 to 2014
 determined that the new CPV-2a variant was more prevalent.

title: Data from: The indicator side of tree microhabitats: a multi-taxon approach based on bats, birds and saproxylic beetles

description: 1. National and international forest biodiversity assessments largely rely
 on indirect indicators, based on elements of forest structure that are
 used as surrogates for species diversity. These proxies are reputedly
 easier and cheaper to assess than biodiversity. Tree microhabitats –
 tree-borne singularities such as cavities, conks of fungi or bark
 characteristics – have gained attention as potential forest biodiversity
 indicators. However, as with most biodiversity indicators, there is a lack
 of scientific evidence documenting their quantitative link with the
 biodiversity they are supposed to assess. 2. We explored the link between
 microhabitat indices and the richness and abundance of three taxonomic
 groups: bats, birds, and saproxylic beetles. Using a nation-wide
 multi-taxon sampling design in France, we compared 213 plots located
 inside and outside strict forest reserves. We hypothesized that the
 positive effect setting aside forest reserves has on biodiversity
 conservation is indirectly due to an increase in the proportion of large
 structural elements (e.g. living trees, standing and lying deadwood).
 These, in turn, are likely to favour the quantity and diversity of
 microhabitats. We analysed the relationship between the abundance and
 species richness of different groups and guilds (e.g. red-listed species,
 forest specialists, cavity dwellers) and microhabitat density and
 diversity. We then used confirmatory structural equation models to assess
 the direct and indirect effects of management abandonment, large
 structural elements and microhabitats on the biodiversity of the target
 species. 3. For several groups of birds and bats, the indirect effect of
 management abandonment and large structural elements on biodiversity was
 mediated by microhabitats. However, the magnitude of the link between
 microhabitat indices and biodiversity was moderate. In particular,
 saproxylic beetles’ biodiversity was poorly explained by microhabitats,
 large structural elements or management abandonment. 4. Synthesis and
 applications: Tree microhabitats may serve as indicators for bats and
 birds, but they are not a universal biodiversity indicator. Rather,
 compared to large structural elements, they most likely have a
 complementary role to biodiversity. In terms of forest management and
 conservation, preserving diversity of microhabitats at the local scale
 benefits several groups of both bats and birds.

title: Data from: Interacting with the enemy: indirect effects of personality on conspecific aggression in crickets

description: In animal contests, individuals respond plastically to the phenotypes of
 the opponents that they confront. These “opponent”—or “indirect”—effects
 are often repeatable, for example, certain opponents consistently elicit
 more or less aggressiveness in others. “Personality” (repeatable
 among-individual variation in behavior) has been proposed as an important
 source of indirect effects. Here, we repeatedly assayed aggressiveness of
 wild-caught adult male field crickets Gryllus campestris in staged dyadic
 fights, measuring aggressiveness of both contestants. Measurements of
 their personality in nonsocial contexts (activity and exploration
 behavior) enabled us to ask whether personality caused indirect effects on
 aggressiveness. Activity, exploration, and aggressiveness were positively
 associated into a behavioral syndrome eliciting aggressiveness in
 conspecifics, providing direct evidence for the role of personality in
 causing indirect effects. Our findings imply that a multivariate view of
 phenotypes that includes indirect effects greatly improves our ability to
 understand the ecology and evolution of behavior.

title: Data from: Socially selected ornaments and fitness: signals of fighting ability in paper wasps are positively associated with survival, reproductive success, and rank

description: Many animals have ornaments that mediate choice and competition in social
 and sexual contexts. Individuals with elaborate sexual ornaments typically
 have higher fitness than those with less elaborate ornaments, but less is
 known about whether socially selected ornaments are associated with
 fitness. Here, we test the relationship between fitness and facial
 patterns that are a socially-selected signal of fighting ability in
 Polistes dominula wasps. We found wasps that signal higher fighting
 ability have larger nests, are more likely to survive harsh winters, and
 obtain higher dominance rank than wasps that signal lower fighting
 ability. In comparison, body weight was not associated with fitness.
 Larger wasps were dominant over smaller wasps, but showed no difference
 nest size or survival. Overall, the positive relationship between wasp
 facial patterns and fitness indicates that receivers can obtain diverse
 information about a signaler's phenotypic quality by paying attention
 to socially selected ornaments. Therefore, there are surprisingly strong
 parallels between the information conveyed by socially and sexually
 selected signals. Similar fitness relationships in social and sexually
 selected signals may be one reason it can be difficult to distinguish the
 role of social versus sexual selection in ornament evolution.
