Abstract Population declines may promote interspecific hybridization due to the shortage of conspecific mates (Hubb’s ‘desperation’ hypothesis), thus greatly increasing risk species extinction. Yet, confirming this process in wild has proved elusive. Here we combine camera-trapping and molecular surveys over seven years document demographic processes associated with introgressive between critically endangered giant sable antelope ( Hippotragus niger variani ) naturally sympatric roan H....
A new species of red toad, from the previously monotypic genus Schismaderma, is described. The was found in Malanje Province, and seems endemic to central Angola, occurring approximately 500 km west closest known records Schismaderma carens. Unusual adult colouration geographical distance remaining S. carens populations suggested specific differentiation. In an integrative approach, we compared toads Angola with across entire range, including molecular data, morphology adults tadpoles, male...
The global environmental crisis has reinforced the importance of improving documentation geographical distributions extant species. With this aim, species inventories specific locations or regions are a high priority, especially so in poorly explored areas. Cabinda Province, an Angolan enclave located between Republic Congo and Democratic (DRC), represents one most enigmatic areas Africa. No detailed within its protected (namely, Mayombe National Park) exist. Furthermore, region presents...
Angola has experienced an incredible increase of the knowledge its herpetofauna over past decade. However, accurate biodiversity inventories remain deficient for certain regions particular conservation interest. We therefore provide updated checklist Iona National Park’s herpetofauna, with 75 recorded species, including five amphibians and 70 reptiles, 40 these first time in Park. These species comprise ~80% reptile diversity Namibe Province. Therefore, this work recognises Park as...
Abstract We developed a biogeographical regionalization of Angolan mammals based on data collected before major declines occurred during the civil war (1975–2002). In terms its biodiversity, A ngola is one least known all African countries. used 9880 grid records 140 species (rodents, ungulates and carnivores) mainly in 1930–80, at quarter degree cell resolution. Biogeographical regions were identified by using cluster analysis, β sim dissimilarity matrices hierarchical classification Ward's...
Genome-wide assessment of genetic diversity has the potential to increase ability understand admixture, inbreeding, kinship and erosion affecting both captive (ex situ) wild (in populations threatened species. The sable antelope (Hippotragus niger), native savannah woodlands sub-Saharan Africa, is a species that being managed ex situ in public (zoo) private (ranch) collections United States. Our objective was develop whole genome sequence resources will serve as foundation for characterizing...
Abstract The evolutionary history of African ungulates has been explained largely in the light Pleistocene climatic oscillations and way these influenced distribution vegetation types, leading to range expansions and/or isolation refugia. In contrast, comparatively fewer studies have addressed continent’s environmental heterogeneity role played by its geomorphological barriers. this study, we performed a range‐wide analysis complete mitogenomes sable antelope ( Hippotragus niger ) explore...
A new species of limestone-dwelling Bent-toed gecko (genus Cyrtodactylus) is described from Nino Konis Santana National Park in the far-east region Timor-Leste. Both genetic and morphological data strongly support evolutionary distinctness species, which we describe herein as Cyrtodactylussantanasp. nov. Phylogenetic analysis based on ND2 mitochondrial gene inferred part C.darmandvillei group with close affinities to C.batucolus, C.seribuatensis, C.petani, C.sadleiri, two undescribed...
The suggestion that the summer distribution of Red‐legged Partridges Alectoris rufa in Mediterranean region is determined by availability surface water was examined on agricultural farm, Alto Alentejo, southern Portugal. Partridge coveys were surveyed between 15 July and August 1993 1994. Using a vector‐based Geographic Information System, we assessed, for each covey location locations double number random points, distance to nearest point, field boundaries, lines land use classes....
The genus Lygodactylus Gray is a species-rich group of small, diurnal geckos distributed in Africa, Madagascar, and South America. divided into several species groups based on morphological characters, biogeographical affinities and/or phylogenetic investigations. To date, some these still contain candidate species. One species, provisionally designed as L. sp. B (a single female from Cameroon), had been placed phylogenetically within the East African scheffleri-group. Furthermore, it shares...
An omnibus procedure for Alectoris partridges density estimation is still lacking. The suitability of driven line and strip transect sampling estimating red‐legged partridge rufa densities on mixed farmland, in southern Portugal, March, May July 1993 1994 was evaluated. Driven counts along a grid dirt tracks were performed compared to early spring territory mapping counts. Distance data sets exhibited prominent peaks near the origin, apparently caused by attraction birds tracks;...
Abstract The giant sable antelope ( H ippotragus niger variani ) is a critically endangered subspecies with range restricted to small area in the A ngolan plateau. It known display geophagic behaviour, eating soil of some M acrotermes termitaria. aim this study was understand importance behaviour for and other ungulates sharing its range. We identified termite mounds used geophagy based on local information confirmed by self‐triggering cameras. collected analysed samples seven termitaria...
In 1944 Loveridge described two new geckos from Angola Afroedura karroica bogerti and Pachydactylus scutatus angolensis. The descriptions of both species have vague confusing type localities refinements are suggested based on early expedition reports historical accounts the region a review cartographic material. Numerous distribution records reported for expeditions undertaken 1956–2016 by authors or their colleagues. taxonomic status has changed but material diverse habitats altitudes...
Abstract Lygodactylus is the most speciose gekkonid group in Africa, with several additional, candidate species already identified from previous studies. However, mainland groups remain only partially resolved, and there are taxonomic inconsistencies. gutturalis was described Guinea-Bissau 1870s since then, has been recorded West to East it widely distributed through different biomes ecoregions. this taxon never studied detail. In work, we use an integrative approach, including molecular...
Secondary sympatry amongst sister lineages is strongly associated with genetic and ecological divergence. This pattern suggests that for closely related species to coexist in secondary sympatry, they must accumulate differences traits mediate and/or reproductive isolation. Here, we characterized inter- intraspecific divergence three giant tree frog whose distributions stretch across West Central Africa. Using genome-wide single-nucleotide polymorphism data, demonstrated species-level...
Kassinula is a monotypic genus of small frog in the family Hyperoliidae, only represented by wittei. This species morphologically resembles both Kassina Girard, 1853 and Afrixalus Laurent, 1944, its taxonomic status has been debated for decades. It previously subsumed within Kassina, currently placed as sister to Afrixalus, although it not included any phylogenetic studies until now. poorly museum collections known from fewer than 35 specimens southern Democratic Republic Congo adjacent...
