title: Data from: Difference in parenting in two species of burying beetle, Nicrophorus orbicollis and Nicrophorus vespilloides

description: Burying beetles (Nicrophorus) are model parents among insects, with all
 studied species known to regurgitate flesh from vertebrate carcasses to
 their offspring. However, most studies focus on a very few species, yet
 the interpretation of the function and importance of care is typically
 generalized to all burying beetles. Here we characterize subtle variation
 within and between individuals and sexes, and how this variation differs
 between two species of burying beetle. We find that Nicrophorus orbicollis
 exhibits low variance, with a normal distribution of parental care
 provided during peak care periods. In N. vespilloides, however, the
 distribution is more uniform as values of care are spread across the
 possible phenotypic spectrum. This suggests that there is stabilizing
 selection on care in N. orbicollis, but relaxed or disruptive selection in
 N. vespilloides. Although repeatability was similar between both species,
 transitions from other care behaviors into feeding were more common in N.
 orbicollis than N. vespilloides. Thus, while parenting is coarsely similar
 across the genus, variation in its expression should not be extrapolated
 to all Nicrophorus. We suggest that subtle variation both within and among
 species merits greater attention, and could inform us about the factors
 that lead to different distributions of care.

title: Data from: Birds in space & time: genetic changes accompanying anthropogenic habitat fragmentation in the endangered black-capped vireo (Vireo atricapilla)

description: Anthropogenic alterations of the natural environment can be a potent
 evolutionary force. For species that have specific habitat requirements,
 habitat loss can result in substantial genetic effects, potentially
 impeding future adaptability and evolution. The endangered black-capped
 vireo (Vireo atricapilla) suffered a substantial contraction of breeding
 habitat and population size during much of the 20th century. In a previous
 study we reported significant differentiation between remnant populations,
 but failed to recover a strong genetic signal of bottlenecks. In this
 study, we used a combination of historical and contemporary sampling from
 Oklahoma and Texas to i) determine if population structure and genetic
 diversity have changed over time, and ii) evaluate alternate demographic
 hypotheses using Approximate Bayesian Computation (ABC). We found lower
 genetic diversity and increased differentiation in contemporary samples
 compared to historical samples –indicating non-trivial impacts of
 fragmentation. ABC analysis suggests a bottleneck having occurred in the
 early part of the 20th century, resulting in a magnitude decline in
 effective population size. Genetic monitoring with temporally spaced
 samples, such as used in this present study, can be highly informative for
 assessing the genetic impacts of anthropogenic fragmentation on threatened
 or endangered species, as well as revealing the dynamics of small
 populations over time.

title: Data from: Realized niche and microhabitat selection of the eastern green lizard (Lacerta viridis) at the core and periphery of its distribution range

description: The available range of habitats and suitable abiotic conditions like
 temperature and radiation tend to be narrower towards the periphery of the
 distribution range of species. Peripheral populations of generalist
 species could then be more specialized and have a smaller and
 differentiated realized niche (habitat niche in our study) compared to
 populations at the core. Likewise, patterns of microhabitat selection can
 differ between periphery and core. In our study we compared niche size and
 microhabitat selection among core (Bulgaria) and northern peripheral
 (Germany, Czech Republic) populations of Lacerta viridis and estimated
 niche differentiation among regions. We collected data on vegetation
 structure and abiotic parameters at the microhabitat scale in each region.
 In order to compare niche size among regions and estimate niche
 differentiation we built multidimensional niche hypervolumes. We applied
 generalized linear mixed models and model averaging, accounting for
 spatial autocorrelation when necessary, to analyze microhabitat
 differences among regions and microhabitat selection in each region.
 Peripheral populations were more specialized, having a smaller niche than
 core ones, and their niche differed from that in the core (Sørensen
 overlap in all comparisons &lt; 0.3). Microhabitats at the periphery
 had lower radiation and soil compaction and less structured vegetation.
 Microhabitat selection at the core depended solely on abiotic parameters,
 while at the periphery it was defined by only vegetation structure (Czech
 Republic) or a combination of both, vegetation structure and abiotic
 factors (Germany). Thus, peripheral populations seem to compensate for
 overall harsher climatic conditions by responding to different parameters
 of the microhabitat compared to core populations. We suggest specific
 conservation measures for L. virids in each studied region and point out
 the general implications of a higher specialization degree of peripheral
 populations in relation to climate change and habitat fragmentation.

title: Data from: Weak coordination between leaf structure and function among closely related tomato species

description: Theory predicts that natural selection should favor coordination between
 leaf physiology, biochemistry and anatomical structure along a functional
 trait spectrum from fast, resource-acquisitive syndromes to slow,
 resource-conservative syndromes. However, the coordination hypothesis has
 rarely been tested at a phylogenetic scale most relevant for understanding
 rapid adaptation in the recent past or for the prediction of evolutionary
 trajectories in response to climate change. We used a common garden to
 examine genetically based coordination between leaf traits across 19 wild
 and cultivated tomato taxa. We found weak integration between leaf
 structure (e.g. leaf mass per area) and physiological function
 (photosynthetic rate, biochemical capacity and CO2 diffusion), even though
 all were arrayed in the predicted direction along a ‘fast–slow’ spectrum.
 This suggests considerable scope for unique trait combinations to evolve
 in response to new environments or in crop breeding. In particular, we
 found that partially independent variation in stomatal and mesophyll
 conductance may allow a plant to improve water-use efficiency without
 necessarily sacrificing maximum photosynthetic rates. Our study does not
 imply that functional trait spectra, such as the leaf economics spectrum,
 are unimportant, but that many important axes of variation within a
 taxonomic group may be unique and not generalizable to other taxa.

title: Data from: The first iguanian lizard from the Mesozoic of Africa

description: The fossil record shows that iguanian lizards were widely distributed
 during the Late Cretaceous. However, the biogeographic history and early
 evolution of one of its most diverse and peculiar clades (acrodontans)
 remain poorly known. Here, we present the first Mesozoic acrodontan from
 Africa, which also represents the oldest iguanian lizard from that
 continent. The new taxon comes from the Kem Kem Beds in Morocco
 (Cenomanian, Late Cretaceous) and is based on a partial lower jaw. The new
 taxon presents a number of features that are found only among acrodontan
 lizards and shares greatest similarities with uromastycines, specifically.
 In a combined evidence phylogenetic dataset comprehensive of all major
 acrodontan lineages using multiple tree inference methods (traditional and
 implied weighting maximum-parsimony, and Bayesian inference), we found
 support for the placement of the new species within uromastycines, along
 with Gueragama sulamericana (Late Cretaceous of Brazil). The new fossil
 supports the previously hypothesized widespread geographical distribution
 of acrodontans in Gondwana during the Mesozoic. Additionally, it provides
 the first fossil evidence of uromastycines in the Cretaceous, and the
 ancestry of acrodontan iguanians in Africa.

title: Data from: Mating system variability in a mouthbrooding cichlid fish from a tropical lake

description: Intraspecific variability in mating behavior and disparities between
 social and reproductive behavior add complexity to the description of
 animal mating systems. A previously published field study on a population
 of the maternally mouthbrooding cichlid fish Ctenochromis horei in the
 north of Lake Tanganyika suggested mate monopolization by the most
 dominant male. In the present study, genetic reconstructions of paternity
 in a population in the south of the lake provided no evidence for male
 mate monopolization, as none of the inferred sires had offspring in more
 than one brood. The ability to reconstruct sire genotypes from offspring
 alleles was confirmed by computer simulations. Multiple paternity occurred
 in several broods and was significantly more frequent in the sample taken
 in the rainy season than in the dry season sample (100% of broods versus
 12.5%, respectively; p = 0.0014). The data suggest geographic and temporal
 variation in the mating behavior of C. horei despite its continuous
 year-round reproduction, invariable brood care behavior and
 habitat-specific distribution in the relatively constant and confined
 environment of a tropical lake. Moreover, our data show that inferences on
 the distribution of male reproductive success, if based on each
 geographical or temporal data set alone, would fail to describe the
 potential for sexual selection in this species.

title: Data from: Broad and flexible stable isotope niches in invasive non-native Rattus spp. in anthropogenic and natural habitats of central eastern Madagascar

description: Background: Rodents of the genus Rattus are among the most pervasive and
 successful invasive species, causing major vicissitudes in native
 ecological communities. A broad and flexible generalist diet has been
 suggested as key to the invasion success of Rattus spp. Here, we use an
 indirect approach to better understand foraging niche width, plasticity,
 and overlap within and between introduced Rattus spp. in anthropogenic
 habitats and natural humid forests of Madagascar. Results: Based on stable
 carbon and nitrogen isotope values measured in hair samples of 565
 individual rodents, we found that R. rattus had an extremely wide foraging
 niche, encompassing the isotopic space covered by a complete endemic
 forest-dwelling Malagasy small mammal community. Comparisons of Bayesian
 standard ellipses, as well as (multivariate) mixed-modeling analyses,
 revealed that the stable isotope niche of R. rattus tended to change
 seasonally and differed between natural forests and anthropogenic
 habitats, indicating plasticity in feeding niches. In co-occurrence, R.
 rattus and R. norvegicus partitioned feeding niches. Isotopic mismatch of
 signatures of individual R. rattus and the habitat in which they were
 captured, indicate frequent dispersal movements for this species between
 natural forest and anthropogenic habitats. Conclusions: Since R. rattus
 are known to transmit a number of zoonoses, potentially affecting
 communities of endemic small mammals, as well as humans, these movements
 presumably increase transmission potential. Our results suggest that due
 to their generalist diet and potential movement between natural forest and
 anthropogenic habitats, Rattus spp. might affect native forest-dependent
 Malagasy rodents as competitors, predators, and disease vectors. The
 combination of these effects helps explain the invasion success of Rattus
 spp. and the detrimental effects of this genus on the endemic Malagasy
 rodent fauna.

title: Data from: Evolutionary dynamics of quantitative variation in an adaptive trait at the regional scale: the case of zinc hyperaccumulation in Arabidopsis halleri

description: Metal hyperaccumulation in plants is an ecological trait whose biological
 significance remains debated, in particular because the selective
 pressures that govern its evolutionary dynamics are complex. One of the
 possible causes of quantitative variation in hyperaccumulation may be
 local adaptation to metalliferous soils. Here we explored the population
 genetic structure of Arabidopsis halleri at fourteen metalliferous and
 non-metalliferous sampling sites in Southern Poland. The results were
 integrated with a quantitative assessment of variation in zinc
 hyperaccumulation to trace local adaptation. We identified a clear
 hierarchical structure with two distinct genetic groups at the upper level
 of clustering. Interestingly, these groups corresponded to different
 geographic sub-regions, rather than to ecological types (i.e.
 metallicolous vs non-metallicolous). Also, approximate Bayesian
 computation analyses suggested that the current distribution of A. halleri
 in Southern Poland could be relictual as a result of habitat fragmentation
 caused by climatic shifts during the Holocene, rather than due to recent
 colonization of industrially polluted sites. In addition, we find evidence
 that some non-metallicolous lowland populations may have actually derived
 from metallicolous populations. Meanwhile, the distribution of
 quantitative variation in zinc hyperaccumulation did separate
 metallicolous and non-metallicolous accessions, indicating more recent
 adaptive evolution and diversifying selection between metalliferous and
 non-metalliferous habitats. This suggests that zinc hyperaccumulation
 evolves both ways – towards higher levels at non-metalliferous sites and
 lower levels at metalliferous sites. Our results open a new perspective on
 possible evolutionary relationships between A. halleri edaphic types that
 may inspire future genetic studies of quantitative variation in metal
 hyperaccumulation.

title: Data from: Reproductive interference explains persistence of aggression between species

description: Interspecific territoriality occurs when individuals of different species
 fight over space, and may arise spontaneously when populations of closely
 related territorial species first come into contact. But defence of space
 is costly, and unless the benefits of excluding heterospecifics exceed the
 costs, natural selection should favour divergence in competitor
 recognition until the species no longer interact aggressively. Ordinarily
 males of different species do not compete for mates, but when males cannot
 distinguish females of sympatric species, females may effectively become a
 shared resource. We model how reproductive interference caused by
 undiscriminating males can prevent interspecific divergence, or even cause
 convergence, in traits used to recognize competitors. We then test the
 model in a genus of visually orienting insects and show that, as predicted
 by the model, differences between species pairs in the level of
 reproductive interference, which is causally related to species
 differences in female coloration, are strongly predictive of the current
 level of interspecific aggression. Interspecific reproductive interference
 is very common and we discuss how it may account for the persistence of
 interspecific aggression in many taxonomic groups.

title: Data from: Bottom-up effects of host-plant species diversity and top-down effects of ants interactively increase plant performance

description: While plant diversity is well known to increase primary productivity,
 whether these bottom-up effects are enhanced by reciprocal top-down
 effects from the third trophic level is unknown. We studied whether pine
 tree species diversity, aphid-tending ants and their interaction
 determined plant performance and arthropod community structure. Plant
 diversity had a positive effect on aphids, but only in the presence of
 mutualistic ants, leading to threefold greater number of both groups in
 the tri-specific cultures than in monocultures. Plant diversity increased
 ant abundance not only by increasing aphid number, but also by increasing
 ant recruitment per aphid. The positive effect of diversity on ants in
 turn cascaded down to increase plant performance; diversity increased
 plant growth (but not biomass), and this effect was stronger in the
 presence of ants. Consequently, bottom-up effects of diversity within the
 same genus and guild of plants and top-down effects from the third trophic
 level (predatory ants) interactively increased plant performance.

title: Data from: Phylogenetic diversity reveals hidden patterns related to population source and species pools during restoration

description: A phylogenetic perspective of community assembly can reveal new insights
 into how variation within dominant species interacts with the local
 species pool to influence the structure of restored plant communities.
 Many studies have examined the effect of dominant species in structuring
 plant communities, but few have investigated their effect on phylogenetic
 diversity (PD). We established grassland in a post-agricultural field
 using two population sources (cultivars and local ecotypes) of three
 dominant grasses (Sorghastrum nutans, Andropogon gerardii and
 Schizachyrium scoparium) with three unique pools of subordinate species
 that varied in PD but not taxonomic or life-form diversity. We tested the
 effect of the population source treatment on two metrics of community PD
 (net relatedness index [NRI] and nearest taxon index [NTI]) during the
 first 4 years of restoration. The NRI measures the overall pairwise
 phylogenetic distance between all pairs of taxa in a community. By
 contrast, NTI measures the pairwise distance between closely related taxa
 in a community. Population sources had a transitory effect on community
 phylogenetic structure over time. Local ecotypes decreased the abundance
 of closely related eudicots, monocots (low +NRI and +NTI values) and
 volunteer species (−NTI) more than cultivars. However, population sources
 did not affect ecologically conservative species (i.e. species with
 intermediate-to-poor ecological tolerance and a high degree of fidelity to
 prairie habitats). Thus, cultivars might have a positive effect on
 community phylogenetic diversity more than local ecotypes by decreasing
 the abundance of a phylogenetically diverse community of less closely
 related volunteer species. Differences in PD of seed mixes were maintained
 in the community of high-fidelity species, but did not affect PD of the
 unsown (volunteer) species in the assembling community. Synthesis and
 applications. This is the first experiment to show consequences of using
 different seed sources on phylogenetic diversity (PD) in grassland
 restoration. Phylogenetics can reveal the effects of population sources on
 the abundance of volunteer species not evident through traditional
 analyses of species diversity. The PD of seed mixes or establishing
 communities, or other assessments of phylogenetic relationships, by
 restoration practitioners is recommended as a metric to allow consequences
 of the evolutionary patterns among species to be included in conservation
 planning. Increased accessibility of phylogenetic tools will allow the
 application of PD in restoration monitoring.
