Perched on the Plateau: Speciation in a Cape Fold Mountain Velvet Worm Clade, With the Description of Seven New Species (Onychophora: Peripatopsidae: Peripatopsis) From South Afric...
प्रकाशित 2025-04-01“…Divergence time estimations indicated that the Miocene epochs was a major period of cladogenesis. The seven novel velvet worm species, P. barnardi sp. nov., P. fernkloofi sp. nov., P. jonkershoeki sp. nov., P. kogelbergi sp. nov., P. landroskoppie sp. nov., P. limietbergi sp. nov., and P. palmeri sp. nov., are herein described.…”ABSTRACT During the present study, we re‐examined species boundaries in three mountain‐dwelling velvet worm species complexes (Peripatopsis balfouri s.l., P. bolandi s.l. and P. purpureus s.l.) along the Cape Fold Mountains of South Africa. We obtained DNA sequence data for both the mitochondrial cy...

New evidence for the co-occurrence of two genera of Paleoparadoxiidae (Mammalia, Desmostylia) from the Middle Miocene of Japan: insights into taxonomic status and paleodiversity in...
प्रकाशित 2025-07-01“…This represents the first record of two genera of Paleoparadoxiidae in the same locality and horizon, with the potential to provide valuable insights into cladogenesis and morphological diversification within this family. …”Desmostylia, an extinct order of marine mammals, includes two major families: Paleoparadoxiidae and Desmostylidae. Within Paleoparadoxiidae, three genera—Archaeoparadoxia, Paleoparadoxia, and Neoparadoxia—have been identified, with Paleoparadoxia being the only genus found on both coasts of the Nort...

Timing and directionality of Triatominae (Hemiptera, Reduviidae) lineage dispersals in the Neotropics
प्रकाशित 2025-07-01“…Using a time-calibrated phylogeny derived from genomic data and fossil evidence, anagenetic dispersals were modeled by the dispersal-extinction-cladogenesis (DEC) model followed by biogeographic stochastic mappings (BSM). …”Triatominae , commonly known as kissing bugs, are hematophagous insects of significant epidemiological concern due to their role as vectors for Trypanosoma cruzi, the causative agent of Chagas disease. Their widespread distribution across the Americas is a result of complex evolutionary and bio...

Discordant population structure inferred from male- and female-type mtDNAs from Macoma balthica, a bivalve species characterized by doubly uniparental inheritance of mitochondria
प्रकाशित 2025-03-01“…Both genes supported a scenario of cladogenesis of M.b. rubra clades prior to the last glacial maximum. …”Doubly Uniparental Inheritance (DUI) of mitochondria is a remarkable exception to the Strictly Maternal Inheritance (SMI) in metazoans. In species characterized by DUI — almost exclusively gonochoric bivalve mollusks — females (F) transmit mitochondria to offspring of both sexes, while males (M) pas...
