Amphibian chytridiomycosis has caused precipitous declines in hundreds of species worldwide. By tracking mountain chicken (Leptodactylus fallax) populations before, during and after the emergence of chytridiomycosis, we quantified the real-time species level impacts of this disease. We report a range-wide species decline amongst the fastest ever recorded, with a loss of over 85% of the population in fewer than 18 months on Dominica and near extinction on Montserrat. Genetic diversity declined in the wild, but emergency measures to establish a captive assurance population captured a representative sample of genetic diversity from Montserrat. If the Convention on Biological Diversity’s targets are to be met, it is important to evaluate the reasons why they appear consistently unattainable. The emergence of chytridiomycosis in the mountain chicken was predictable, but the decline could not be prevented. There is an urgent need to build mitigation capacity where amphibians are at risk from chytridiomycosis.

During a recent biodiversity survey in Djibouti, nineteen small mammal species were collected, including six bats and three rodents not previously recorded from the country. Records of a further three species, based on specimens from the zoological collections of the Museum National d'Histoire Naturelle, Paris, are published for the first time. A second record of Lophiomys imhausii is included, based on a photograph. The thirty-nine species of Insectivora, Macroscelidea, Chiroptera, Hyracoidea, and Rodentia now known from the country are listed. Brief descriptions and measurements, where available, of twenty-one species are given together with notes on their distribution, ecological parameters, and conservation status. Previous publications on the mammal fauna of Djibouti are reviewed.Resume. -Au cours d'une recente exploration de la biodiversite a Djibouti, 19 especes de petits mammiferes ont ete collectees, parmi lesquelles 6 chauves-souris et 3 rongeurs nouveaux pour la region. Trois autres especes, d'apres les collections du MNHN, Paris, sont publiees pour la premiere fois. La seconde observation de Lophiomys imhausii est incluse d'apres une photographic. Les 39 especes d'Insectivores, Macroscelides, Chiropteres, Hyraco'ides, et Rongeurs actuellement connus de ce pays sont cites.De breves descriptions et des mensurations de 21 especes sont donnees, avec des notes sur leur repartition, des parametres ecologiques et leur Statut de conservation. Les precedentes publications sur la faune de Djibouti sont passees en revue.
