Data from: Genomic footprint of cladogenesis revealed through RADseq and Sanger sequencing demonstrates congruent patterns in the velvet worm Peripatopsis sedgwicki species complex (Onychophora: Peripatopsidae)
<p>In the present study, first generation DNA sequencing (mitochondrial cytochrome c oxidase subunit one, <em>COI</em>) and reduced-representative genomic RADseq data were used to understand the patterns and processes of diversification of the velvet worm, <em>Peripatopsis sedgwicki</em> species complex across its distribution range in South Africa. For the RADseq data, three datasets (two primary and one supplementary) were generated corresponding to 1259 - 11,468 SNPs, in order to assess the species diversity and phylogeographic of the species complex. Tree topologies for the two primary datasets were inferred using maximum likelihood and Bayesian inferences methods. Phylogenetic analyses using the <em>COI </em>datasets retrieved four distinct, statistically well-supported clades within the species complex. Five species delimitation methods applied to the <em>COI </em>data (ASAP, bPTP, bGMYC, STACEY, and iBPP) all showed support for the distinction of the Fort Fordyce Nature Reserve specimens. In the main <em>P. sedgwicki </em>species complex, the species delimitation methods revealed a variable number of operational taxonomic units and overestimated the number of putative taxa. Divergence time estimates coupled with the geographic exclusivity of species and phylogeographic results suggest recent cladogenesis during the Plio/Pleistocene. The RADseq were subjected to a principal components analysis and a discriminant analysis of principal components, under a maximum-likelihood framework. The latter results corroborate the four main clades observed using the <em>COI</em> data, however, applying additional filtering revealed additional diversity. The high overall congruence observed between the RADseq and <em>COI </em>data suggests that first generation sequence data remain a cheap and effective method for evolutionary studies, although RADseq does provide a far greater resolution of contemporary temporo-spatial patterns. </p>

Data from: Exploring the impact of habitat size on phylogeographic patterning in the Overberg velvet worm Peripatopsis overbergiensis (Onychophora: Peripatopsidae)
Evolutionary relationships in the velvet worm species, Peripatopsis overbergiensis, were examined in 3 forest areas in the Overberg region of South Africa to explore the impact of historical habitat fragmentation on the population genetic structure of the species. We collected 84 P. overbergiensis specimens from Grootvadersbosch, Koppie Alleen, and Marloth Nature Reserves and sequenced all these specimens for the cytochrome c oxidase subunit I (COI) locus, whereas a subset of 13 specimens were also sequenced for the 18S rRNA locus. Phylogenetic analyses of the 20 unique COI haplotypes revealed 4 genetically distinct clades, a result that is corroborated by the haplotype network. A hierarchical analysis of genetic variation was performed on the COI haplotype data within the 2 large forested areas, Grootvadersbosch and Marloth Nature Reserves, and across all 3 of the sample localities. These results revealed low haplotypic and nucleotide diversity within the largest Grootvadersbosch Nature Reserve forest and high haplotypic and nucleotide diversity within the fragmented Marloth Nature Reserve forest, whereas Koppie Alleen had the lowest haplotypic and nucleotide diversity. Across all 3 main localities statistically significant F ST values were found, together with the absence of shared haplotypes indicating the absence of maternal gene flow. Divergence time estimations based on the 20 COI haplotypes calculated in BEAST suggest a Pleistocene/Holocene divergence between the 4 clades as a result of habitat fragmentation and the aridification of the region. Our results indicate that conservation efforts should also prioritize linked, smaller fragmented habitats together with continuous habitats to maximize the genetic diversity of saproxylic fauna.
