Abstract Several African mammals exhibit a phylogeographic pattern where closely related taxa are split between West/Central and East/Southern Africa, but their evolutionary relationships histories remain controversial. Bushpigs ( Potamochoerus larvatus ) red river hogs P. porcus recognised as separate species due to morphological distinctions, perceived lack of interbreeding at contact, putatively old divergence times, historically, they were considered conspecific. Moreover, the presence...

Societal Impact Statement To better understand the impact of human settlement on vegetation distribution and disturbance regimes in Madagascar, 2021 Malagasy Grassy Biomes Workshop called for an examination role extinct megafauna determining historic habitat mosaics across regions that are today dominated by vast treeless grasslands. A systematic literature review facilitated reconstruction evaluation giant tortoise habitat, feeding habitats, diets Aldabrachelys impacts regimes. In...
SUMMARY Newcastle disease (ND) is one of the most important poultry diseases worldwide and can lead to annual losses up 80% backyard chickens in Africa. All bird species are considered susceptible ND virus (NDV) infection but little known about role that wild birds play epidemiology virus. We present a long-term monitoring 9000 four African countries. Overall, 3·06% were PCR-positive for NDV infection, with prevalence ranging from 0% 10% depending on season, site considered. Our study shows...
To date, infectious bronchitis virus (IBV) is potentially found in wild birds of different species. This work reports the survey coronaviruses from Madagascar based on targeting a conserved genome sequence among groups CoVs. Phylogenetic analyses revealed presence gammacoronaviruses species Gruiformes, Passeriformes, Ciconiiformes, Anseriformes, and Charadriiformes. Furthermore, some sequences were related to various IBV strains. Aquatic migratory may play an important role maintenance...
Abstract Madagascar is recognized both for its unparalleled biodiversity and the high level of threat suffered by this biodiversity, associated in particular with anthropogenic deforestation. Despite sustained efforts to fight poverty curb deforestation, forest cover rapidly decreasing. To try explain why it so difficult stop deforestation Madagascar, we analysed recent process Western through satellite image analysis field surveys. We show that has increased from less than 0.9%/yr on...
From January 2005 to December 2007 field surveys were conducted in the Central Highlands region of Vietnam assess status banteng Bos javanicus birmanicus. The population was estimated be 74–103. It has declined by at least 50% since mid- 1990s and species is likely go extinct near future. Remaining herds are small, although recruitment still exists. Large portions species' range early no longer occupied maximum area occupancy c. 2,670 km2. Only five disconnected populations persist. most...
The geographical distribution and impact on animal human health of both West Nile Usutu viruses, two flaviviruses the Japanese encephalitis complex, have been increasing during past decades. Both viruses circulate in Europe Africa within a natural cycle between wild birds mosquitoes, mainly from Culex genus. We retrospectively analyzed sera domestic sampled 2008 wetlands, namely Inner Niger Delta, Mali, Lake Alaotra area, Madagascar. Sera were first tested using commercial ID Screen...
As the biodiversity crisis accelerates, stakes are higher for threatened plants and animals. Rebuilding health of our planet will require addressing underlying threats at many scales, including habitat loss climate change. Conservation interventions such as protection, management, restoration, predator control, translocation, genetic rescue, biological control have potential to help or endangered species avert extinction. These existing, well-tested methods can be complemented augmented by...
Abstract Evidence from DNA phylogeny, Plio‐Pleistocene ocean currents, giant tortoise dispersal, evolution of plant defences, radiocarbon dates and archaeology indicates that the endemic tortoises on Mascarenes Seychelles colonized naturally were not translocated there by humans.
Recent growth in industrialization and the modernization of agricultural activities, combined with human population growth, has greatly modified China’s natural environment, particularly vicinity large cities. We compared avifauna checklists made between 1877 1938 current to determine extent local bird extinctions during last century greater Beijing area. Our study shows that 411 species recorded from 1877–1938, 45 (10.9%) were no longer 2004–2006. Birds as ‘rare’ more likely have...
The island of Madagascar, situated off the southeast coast Africa, shows first evidence human presence ~ 10,000 years ago; however, other archaeological data indicates a settlement modern peoples distinctly more recent, perhaps > 1500 ago. Bushpigs genus Potamochoerus (family Suidae), are today widely distributed in Madagascar and presumed to have been introduced from Africa at some stage by immigrants island. However, disparities about their origins presented literature, including...
Conservation strategies of Malagasy turtles and tortoises are based principally on the captive - breeding these species, with ultimate aim their possible reintroduction in wild. Given current precarious conservation status endemic turtle tortoise it is clear that this approach has been a failure. Instead being used to complement situ approaches for number years efforts have as an alternative. It essential develop species empirical data, not only subjective vision NGOs strong interest ex...
Pyxis arachnoides is a Critically Endangered Malagasy tortoise for which little data about its natural history and genetic variation are available. This lack of knowledge complicates undertaking conservation measures considering diversity. Here, we describe six new microsatellites from wild specimens several localities, the cross amplification two Astrochelys radiata microsatellites. Of these microsatellites, monomorphic among three distinct subspecies closely related species, while...
