Article Reference Miscellanea Herpetologica Gabonica VII
We present new Gabonese locality records, ecological data or unpublished museum material for Crocodylus niloticus (Crocodylidae), Trionyx triunguis (Trionychidae), Agama lebretoni (Agamidae), Hemidactylus fasciatus and H. mabouia (Gekkonidae), Gastropholis echinata (Lacertidae), Trachylepis albilabris (Scincidae), Afrotyphlops angolensis (Typhlopidae), Dipsadoboa viridis, Hapsidophrys smaragdinus, Toxicodryas pulverulenta (Colubridae), Naja melanoleuca (Elapidae), Lamprophis olivaceus, Psammophis cf. phillipsii (Lamprophiidae), Natriciteres fuliginoides (Natricidae), Causus lichtensteinii and C. maculatus (Viperidae). We document predation cases by Hapsidophrys smaragdinus on Hemidactylus mabouia and Trachylepis albilabris, by Naja melanoleuca on Sclerophrys regularis (Anura: Bufonidae) and by Psammophis cf. phillipsii on Phrynobatrachus auritus (Anura: Phrynobatrachidae), and consumption of Arius latiscutatus (Siluriformes: Ariidae) and Tragelaphus spekii (Cetartiodactyla: Bovidae) by Crocodylus niloticus. We add one, two and one snake species, respectively, to Estuaire, Moyen-Ogooué and Nyanga provinces’ reptile lists. We add four reptile species to the list for Wonga-Wongué Presidential Reserve. We refer all records of Agama agama in Gabon to A. picticauda.

Article Reference Miscellanea Herpetologica Gabonica XV
We present new Gabonese locality records, ecological and morphological data and unpublished material for Pelusios gabonensis (Pelomedusidae), Kinixys erosa (Testudinidae), Hemidactylus mabouia (Gekkonidae), Lepidothyris striatus, Trachylepis affinis (Scincidae), Crotaphopeltis hotamboeia, Dipsadoboa underwoodi and D. viridis (Colubridae), Dendroaspis jamesoni, Naja annulata annulata, N. melanoleuca and N. nigricollis (Elapidae), Atractaspis boulengeri, Limaformosa savorgnani, Polemon fulvicollis, Psammophis mossambicus (Lamprophiidae) and Natriciteres fuliginoides (Natricidae). One skink and two snake species are newly recorded from Haut-Ogooué and Ngounié provinces, respectively. We attribute all records of Psammophis spp. in Gabon to P. mossambicus. We report a case of predation by a Common chimpanzee (Pan troglodytes) on Kinixys erosa in Lopé National Park, by Crotaphopeltis hotamboeia on the Cameroon toad Sclerophrys camerunensis (Anura: Bufonidae), and by a Naja annulata annulata on Thollon's robber tetra Brycinus tholloni (Characiformes: Alestidae).

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.
