Faecal samples are of great value as a non-invasive means to gather information on the genetics, distribution, demography, diet and parasite infestation of endangered species. Direct shotgun sequencing of faecal DNA could give information on these simultaneously, but this approach is largely untested. Here, we used two faecal samples to characterize the(More)
Rapid habitat loss and degradation are responsible for population decline in a growing number of species. Understanding the natural history of these species is important for designing conservation strategies, such as habitat enhancements or ex-situ conservation. The acquisition of observational data may be difficult for rare and declining species, but(More)
Previous studies of meta-analyses found significantly positive correlations between primate species richness and rainfall for Africa, Madagascar and the Neotropics, with the exception of Asia, leaving the open question whether that anomaly is the result of sampling bias, biogeography, or some other factor. This study re-examines the question using modelled(More)
Characterizing trophic networks is fundamental to many questions in ecology, but this typically requires painstaking efforts, especially to identify the diet of small generalist predators. Several attempts have been devoted to develop suitable molecular tools to determine predatory trophic interactions through gut content analysis, and the challenge has(More)
We here test the proposition that changes in the barcoding region of COI are commonly involved in speciation through intergenomic conflict. We demonstrate that this is unlikely given that even with incomplete taxon sampling, 78-90% of closely-related animal species have identical COI amino acid sequences. In addition, in those cases where amino acid(More)
The Tonkin snub-nosed monkey (Rhinopithecus avunculus) with a global population of <250 is listed as critically endangered. It is endemic to northeastern Vietnam and was feared extinct until its rediscovery in 1989. The largest single population of R. avunculus consists of 125–130 individuals in an area of forest called Khau Ca in Ha Giang Province. We used(More)
Freshwater habitats are of high conservation value and provide a wide range of ecosystem services. Effective management requires regular monitoring. However, conventional methods based on direct observation or specimen collection are so invasive, expensive and labour-intensive that frequent monitoring is uncommon. Here, we test whether the evaluation of(More)
