Data from: Tracing the patterns of non-marine turtle richness from Triassic–Palaeogene: from origin through global spread
<p>Turtles are key components of modern vertebrate faunas and it is predicted that their diversity and distributions will be affected by anthropogenic climate change. Despite this, few studies have attempted to provide baseline data on turtle taxonomic richness through time or assess their past responses to global environmental change. We used the extensive Triassic–Palaeogene (252–23 Ma) fossil record of terrestrial and freshwater turtles to investigate diversity patterns, finding substantial variation in richness through time and between continents. Subsampled turtle richness was low globally from their Triassic origin until the Late Jurassic. There is strong evidence for high richness in the earliest Cretaceous of Europe. Richness was especially high following the Cretaceous Thermal Maximum and declined in all continents by the end-Cretaceous. At the K-Pg boundary, South American richness levels changed little while North American richness increased. Subsampled North American turtle richness was very high during the earliest Palaeogene (Danian) while South American richness was low; informative data on earliest Palaeogene turtle richness are lacking elsewhere. However, the Selandian–Thanetian interval, approximately 5 million years after the K-Pg mass extinction, shows low turtle richness in Asia, Europe and South America. This suggests the occurrence of exceptional turtle richness in the post-extinction Paleocene fauna of North America is not globally representative. Richness decreased over the Eocene–Oligocene boundary in North America but increased to its greatest known level for Europe, implying very different responses to dramatic Eocene–Oligocene climatic shifts. Time series regressions suggest number of formations sampled and palaeotemperature are the primary influencers of face-value richness counts, but additional factors not tested here may also be involved.</p>

Data from: Patterns of colonization and spread in the fungal spruce pathogen Onnia tomentosa
The basidiomycetous fungus Onnia tomentosa is one of the most widespread root rot pathogens in North America. Although the disease is more severe on spruce and pine trees, this pathogen can infect several coniferous species. In order to study the population structure of O. tomentosa, we harvested 180 basidiocarps in a 45-year-old white spruce plantation in western Quebec in autumn 1997, and extracted DNA directly from individual basidiocarps. Using a combination of spatial coordinates and molecular data based on the analysis of two mitochondrial and three nuclear loci, we measured the average genet size and molecular diversity and assessed the relative contribution of basidiospores and vegetative growth to the stand colonization. Most of the sampled basidiocarps that clustered spatially belonged to the same genet. A total of thirty-seven discrete multilocus genets of an average size of 3.42 m were obtained. The genet size distribution was skewed toward smaller genets (< 3 m) that displayed higher diversity than the larger genets (> 3 m). The nuclear loci were in Hardy-Weinberg equilibrium in the larger genets, but not in the smaller genets, which displayed a deficiency of heterozygotes. This suggests a Wahlund effect, whereby different colonization events resulted in expected heterozygosity higher than observed heterozygosity. Using an estimate of the growth rate of the fungus, only a few of the largest genets were approximately the age of the plantation. These observations are consistent with the colonization by basidiospores subsequent to site preparation and tree planting followed by secondary colonization events and vegetative spread.
Data from: Latitudinal divergence in a wide-spread amphibian: contrasting patterns of neutral and adaptive genomic variation
Stochastic effects from demographic processes and selection are expected to shape the distribution of genetic variation in spatially heterogeneous environments. As the amount of genetic variation is central for long-term persistence of populations, understanding how these processes affect variation over large-scale geographic gradients is pivotal. We investigated the distribution of neutral and putatively adaptive genetic variation, and reconstructed demographic history in the moor frog (Rana arvalis) using 136 individuals from 15 populations along a 1700 km latitudinal gradient from northern Germany to northern Sweden. Using ddRAD-seq we obtained 27590 SNPs, and identified differentiation outliers and SNPs associated with growing season length. Populations grouped into a southern and a northern cluster, representing two phylogeographical lineages from different post-glacial colonization routes. Hybrid index estimation and demographic model selection showed strong support for a southern and northern lineage and evidence of gene flow between regions located on each side of a contact zone. However, patterns of past gene flow over the contact zone differed between neutral and putatively adaptive SNPs. While neutral nucleotide diversity was higher along the southern than the northern part of the gradient, nucleotide diversity in differentiation outliers showed the opposite pattern suggesting differences in the relative strength of selection and drift along the gradient. Variation associated with growing season length decreased with latitude along the southern part of the gradient, but not along the northern part where variation was lower, suggesting stronger climate-mediated selection in the north. Outlier SNPs included loci involved in immunity and developmental processes.
