Article Reference Octet Stream Miscellanea Herpetologica Gabonica XX
We present new Gabonese locality records for Mecistops leptorhynchus, Osteolaemus tetraspis (Crocodylidae), Ichnotropis bivittata (Lacertidae), Lacertaspis reichenowii (Scincidae), Varanus ornatus (Varanidae), Dipsadoboa weileri, Grayia ornata (first record from Gabon of the striped form), Philothamnus hughesi, Thelotornis kirtlandii, Toxicodryas blandingii (Colubridae), Dendroaspis jamesoni jamesoni, Naja annulata (Elapidae), Bothrolycus ater, Hormonotus modestus, Mehelya poensis (Lamprophiidae), Prosymna ambigua (first documented record for Gabon) (Prosymnidae), Python sebae (Pythonidae), Bitis arietans and B. nasicornis (tenth reptile species recorded from a cave in Gabon) (Viperidae). One species is newly recorded from Loango National Park, three from Haut-Ogooué Province, and one from Nyanga Province. We report a fatal envenomation presumably due to Dendroaspis jamesoni jamesoni in Ogooué-Ivindo Province. We reject a record of Grayia ornata from Mount Kupe, Cameroon.

We present new Gabonese locality records for Kinixys erosa (Testudinidae), Trioceros camerunensis and T. oweni (Chamaeleonidae), Hemidactylus coalescens (Gekkonidae), Holaspis guentheri (Lacertidae), Mochlus striatus, Panaspis breviceps (Scincidae), Dipsadoboa weileri, Grayia ornata, Thelotornis kirtlandii, Thrasops flavigularis, Toxicodryas adamantea (Colubridae), Atractaspis corpulenta corpulenta, Boaedon virgatus, Bothrolycus ater, Hormonotus modestus, Lycophidion laterale, Mehelya stenophthalmus (Lamprophiidae) and Hydraethiops melanogaster (Natricidae). Four species are recorded for the first time from Ngounié Province, one from Estuaire Province, two from Moyen-Ogooué Province, one from Arboretum Raponda-Walker, and five for Crystal Mounts National Park. We report several new records of foraging heights in trees.

Article Reference Mitochondrial DNA diversity and evolution of the Pleistocene cave bear complex
Cave bears are among the most well known extinct Pleistocene mammals. Their biogeography and taxonomy, along with the factors that led to their extinction, have been subject to long-standing controversy. Here, we reconstruct the phylogeography as well as the temporal and spatial population dynamics of cave bears across their range using mitochondrial DNA control region sequences from 77 published as well as 65 new cave bear samples, Our analyses reveal a dramatic loss of genetic diversity in cave bear populations after 30,000 years before present and provide evidence for a range decline from east to west towards the onset of the last glacial maximum. Our results also suggest that the three major haplogroups within cave bears, which may correspond to distinct species, were previously more widespread, with relict populations in remote and alpine areas still harbouring haplotypes that have disappeared from most of their previous range. Applying a phylogenetic dating approach, we estimated the age of the oldest of our samples, originating from the Yana River region in north-eastern Siberia, to be around 178,000 years, which confirms a previous estimate of a Middle Pleistocene age based on its stratigraphic position. Our results extend our knowledge about the evolutionary history of cave bears, but they also show that to unravel the complexities of cave bear evolution future ancient DNA studies on this Pleistocene species will need to go beyond short mitochondrial DNA fragments, including full mitochondrial genomes as well as nuclear DNA sequences.

Article Reference Mitogenomics reveals high synteny and long evolutionary histories of sympatric cryptic nematode species
Species with seemingly identical morphology but with distinct genetic differences are abundant in the marine environment and frequently co-occur in the same habitat. Such cryptic species are typically delineated using a limited number of mitochondrial and/or nuclear marker genes, which do not yield information on gene order and gene content of the genomes under consideration. We used next-generation sequencing to study the composition of the mitochondrial genomes of four sympatrically distributed cryptic species of the Litoditis marina species complex (PmI, PmII, PmIII, and PmIV). The ecology, biology, and natural occurrence of these four species are well known, but the evolutionary processes behind this cryptic speciation remain largely unknown. The gene order of the mitochondrial genomes of the four species was conserved, but differences in genome length, gene length, and codon usage were observed. The atp8 gene was lacking in all four species. Phylogenetic analyses confirm that PmI and PmIV are sister species and that PmIII diverged earliest. The most recent common ancestor of the four cryptic species was estimated to have diverged 16 MYA. Synonymous mutations outnumbered nonsynonymous changes in all protein-encoding genes, with the Complex IV genes (coxI-III) experiencing the strongest purifying selection. Our mitogenomic results show that morphologically similar species can have long evolutionary histories and that PmIII has several differences in genetic makeup compared to the three other species, which may explain why it is better adapted to higher temperatures than the other species.
