Data from: The phylogeographic history of Megistostegium (Malvaceae) in the dry, spiny thickets of southwestern Madagascar using RAD-seq data and ecological niche modeling.
<p class="MsoCommentText">The spiny thicket of southwestern Madagascar represents an extreme and ancient landscape with extraordinary levels of biodiversity and endemism. Few hypotheses exist for explaining speciation in the region and few plant studies have explored hypotheses for species diversification. Here we investigate three species in the endemic genus <i>Megistostegium </i>(Malvaceae) to evaluate phylogeographic structure and explore the roles of climate, soil and paleoclimate oscillations on population divergence and speciation throughout the region. We combine phylogenetic and phylogeographic inference of RADseq data with ecological niche modeling across space and time. Population structure is concurrent with major rivers in the region and we identify a new, potentially important biogeographic break coincident with several landscape features. Our data further suggests that niches occupied by species and populations differ substantially across their distribution. Paleodistribution modelling provide evidence that past climatic change could be responsible for the current distribution, population structure and maintenance of species in <i>Megistostegium.</i></p>

Data for: Sexual dimorphism in ichneumonine parasitic wasps (Hymenoptera: Ichneumonidae: Ichneumoninae) and the neglected influence of the ecological niche
<p>Sexual dimorphism is a ubiquitous phenomenon, but its ecological role and evolutionary significance are still poorly understood in many hyperdiverse lineages. We used geometric morphometrics to characterize and quantify sexual dimorphism in the head and mesosoma of 24 species in the wasp subfamily Ichneumoninae (Hymenoptera: Ichneumonidae). Our results show that sexual dimorphism varies substantially among species but is generally more pronounced on the head, with males occupying a noticeably smaller region of the morphospace than females. Phenotypic trajectory analyses showed a trend towards conserved trajectories in the difference between males and females, indicating that dimorphism seems to manifest as predictable shape changes across species. Species parasitizing pupae, particularly in concealed substrates, were found to have higher sexual dimorphism for the head than species parasitizing more exposed hosts such as larvae. For the mesosoma, this difference was not significant, with the degree of sexual dimorphism more influenced by phylogenetic history. We hypothesize that female head shape has adapted to the demands related to finding hosts in concealed habitats, whereas species that attack exposed or weakly concealed hosts have kept a generalized head shape in both sexes. These results highlight the importance of investigating intersex ecological differences as drivers of sexual dimorphism.</p>
Data for: Functional response metrics explain and predict high but differing ecological impacts of juvenile and adult lionfish
<p>Recent accumulation of evidence across taxa indicates that the ecological impacts of invasive alien species are predictable from their Functional Response (FR; e.g. the maximum feeding rate) and Functional Response Ratio (FRR; the FR attack rate/handling time ratio). Here, we experimentally derive these metrics to predict the ecological impacts of both juvenile and adult lionfish (<em>Pterois volitans</em>), one of the world's most damaging invaders, across representative and likely future prey types. Potentially prey-population destabilising Type II FRs were exhibited by both life stages of lionfish towards four prey species: <em>Artemia salina</em>, <em>Gammarus oceanicus</em>, <em>Palaemonetes varians</em> and <em>Nephrops norvegicus</em>. FR magnitudes revealed ontogenetic shifts in lionfish impacts, while lionfish FRR values were substantially higher than mean FRR values across known damaging invasive taxa. Thus, both life stages of lionfish are predicted to contribute to differing but high ecological impacts across prey communities, including commercially important species. With lionfish invasion ranges currently expanding across multiple regions globally, efforts to reduce lionfish numbers and population size structure, and provision of prey refugia through habitat complexity, might reduce their impacts. However, early detection and complete eradication of individuals located in new regions is advised.</p>
Data from: The ecology of hybrid incompatibilities
<p><span></span></p> <p>Ecologically-mediated selection against hybrids, caused by hybrid phenotypes fitting poorly into available niches, is typically viewed as distinct from selection caused by epistatic Dobzhansky-Muller hybrid incompatibilities. Here, we illustrate how selection against transgressive phenotypes in hybrids manifests as incompatibility. After outlining our logic, we summarize current approaches for studying ecology-based selection on hybrids. We then quantitatively review QTL-mapping studies and find traits differing between parent taxa are typically polygenic. Next, we describe how verbal models of selection on hybrids translate to phenotypic and genetic fitness landscapes, highlighting emerging approaches for detecting polygenic incompatibilities. Finally, in a synthesis of published data, we report that trait transgression—and thus possibly extrinsic hybrid incompatibility—in hybrids escalates with the phenotypic divergence between parents. We discuss conceptual implications and conclude that studying the ecological basis of hybrid incompatibility will facilitate new discoveries about mechanisms of speciation.</p>
