Motivation: DNA methylation plays a crucial role in gene regulation and epigenetic inheritance, making it essential information for studies of genotype-environment interactions. As whole genome sequencing analysis is still expensive at the population level, focus on regions interest. However, data matrices may contain missing some individuals, which can hamper analyses. Here, several methods imputing were evaluated targeted two species. Results: We compare seven different imputation obtained...
The Karoo region of South Africa is a unique and sensitive ecosystem which facing pressure for development due to economic incentives such as mining, farming shale gas exploration. species diversity many taxa in the area largely unknown. A phylogenetic analysis cork-lid trapdoor spider genus, Stasimopus (Stasimopidae) was undertaken order gain insight into relationships between that may be present area. within are challenging identify define using traditional morphological methods high...
Abstract The identification of Stasimopus Simon, 1892 species as well mygalomorph has been a long-standing challenge. This is due to their conservative morphologies the lack quantifiable characters. Ocular patterns have historically used aid in identification, but largely vague and subjective. study was first test for phylogenetic signal this character validate its use description viability it morphospecies identification. results show significant ocular both sexes, validating use. display...
Aim: The genus Stasimopus is endemic to South Africa but has never undergone a phylogeographic review. This study aims unravel the patterns and history of many species which occur in greater Karoo region. Location: region, Time period: 2017-2018 Major taxa studied: Cork-lid trapdoor spider, (15 species). Methods: A fossil-calibrated phylogeny was produced based on three gene regions (CO1, 16S EF-1ɣ) for specimens collected infer dates origin diversification. Demographic analyses were...
The genus Stasimopus is endemic to South Africa but has never undergone a phylogeographic review. This study aims unravel the patterns and history of many species which occur in greater Karoo region. A fossil-calibrated phylogeny was produced based on three gene regions (CO1, 16S EF-1ɣ) for (Cor-k-lid trapdoor spiders) specimens collected region, infer dates origin diversification. Demographic analyses were performed with sufficient sample sizes (> 4). Haplotype networks constructed each...
The genus Stasimopus Simon 1892 is endemic to Southern Africa, but historically largely understudied. This paper provides a taxonomic revision for the species of Karoo region South Africa and includes description nine new (S. dylani sp. nov., S. finni hamartia ignis karooensis malesociatus tera theaei nov. venterstadensis nov.). A genetically matched maraisi Hewitt 1914 male provided. original designated its own An identification key provided occurring in region. first integrative taxonomy...
