Summary The concept of biodiversity conservation relies primarily on protected areas. Yet, areas are influenced by the surrounding anthropogenic matrix as degradation landscapes used humans also has negative consequences species within adjacent protected, non‐degraded ecosystems. Increasing heterogeneity landscape potential to promote in and non‐protected sites. To find options for reconciling land use conservation, we evaluated reptile diversity two Both contained three types habitat:...
Abstract Aim We studied the gecko genus Ebenavia to reconstruct its colonization history, test for anthropogenic versus natural dispersal out of Madagascar, and correlate divergence date estimates our phylogeny with geological age islands in region. Location Madagascar surrounding Western Indian Ocean (Comoros, Mayotte, Mauritius, Pemba). Methods reconstructed covering entire geographical range using a molecular data set three mitochondrial two nuclear markers. estimated times based on...
We provide an updated molecular phylogenetic analysis of global diversity typhlopid and xenotyphlopid blindsnakes, adding a set Madagascan samples sequences additional mitochondrial gene to existing supermatrix nuclear segments. Our data suggest monophyly typhlopids, exclusive introduced Indotyphlops braminus. The Madagascar-endemic clade includes two species previously assigned the genus Lemuriatyphlops (in subfamily Asiatyphlopinae), which were not each others closest relatives. This...
West African torrent-frogs of the genus Odontobatrachus currently belong to a single species: natator (Boulenger, 1905). Recently, molecular results and biogeographic separation led recognition five Operational Taxonomic Units (OTUs) thus identifying species-complex. Based on these insights, morphological analyses more than 150 adult specimens, covering entire distribution family all OTUs, were carried out. Despite strong congruence, combinations characters made differentiation OTUs...
Astylosternus laticephalus sp. nov. Rödel, Hillers, Leaché, Kouamé, Ofori-Boateng, Diaz & Sandberger is described fromeastern Ivory Coast and western central Ghana, compared to occidentalis Parker, 1931 from thewestern part of the Upper Guinea forest zone (western Coast, Liberia, Sierra Leone). Based on a com-prehensive sample, including specimens entire range, latter species re-described. The new char-acterized by body shape typical for frogs genus Astylosternus, but has an...

Agricultural expansions and unsustainable resource extraction increasingly threaten biodiversity worldwide. Thus, knowledge on landscape management opportunities that contribute to conservation provide the necessary natural resources is urgently needed. Community-based can be one solution achieve sustainable provisioning conservation. However, evidence effectiveness of transfers local communities for scarce. We use a case study from south-western Madagascar discuss integration...
Intact soil food webs are pivotal to maintaining essential functions, such as carbon recycling, sequestering, and biomass production. Although the functional role of micro- (e.g., bacteria fungi) macrofauna earthworms) is comparatively well established, importance mesofauna community abundance diversity Acari Collembola) in functionality less clear. We investigated this question a six-month field experiment arable by actively manipulating biodiversity through application two legacy...
Arthroleptis langeri Rödel, Doumbia, Johnson & Hillers 2009 is a genetically and morphologically distinct West African squeaker frog species. It was described based on one individual from forest at 567 m a.s.l. in the East Nimba National Forest, Liberia. However, it believed to be potentially more widespread Western Guinean rainforest ecoregion (Rödel et al. 2009). We herein report additional specimens of this Three frogs were discovered collection Museum d’Histoire Naturelle, Paris...
Wild birds and mammals that feed in agricultural habitats are potentially exposed to pesticides through various routes. The European Food Safety Authority (EFSA) recently published a statement which concluded the current EFSA risk assessment scheme for does not adequately cover bats (Chiroptera). In present study, we take more detailed look at assumptions made regarding direct (dermal) indirect (dietary) exposure of terms their realism potential implications outcomes. Regarding dietary...
