Abstract The underrepresentation of non-Europeans in human genetic studies so far has limited the diversity individuals genomic datasets and led to reduced medical relevance for a large proportion world’s population. Population-specific reference genome as well genome-wide association diverse populations are needed address this issue. Here we describe pilot phase GenomeAsia 100K Project. This includes whole-genome sequencing dataset from 1,739 219 population groups 64 countries across Asia....
Long-tailed macaques (Macaca fascicularis) are an important model species in biomedical research and reliable knowledge about their evolutionary history is essential for inferences. Ten subspecies have been recognized, of which most restricted to small islands Southeast Asia. In contrast, the common long-tailed macaque (M. f. distributed over large parts Asian mainland Sundaland region. To shed more light on phylogeny M. fascicularis, we sequenced complete mitochondrial (mtDNA) genomes 40...
The Malayan tiger (Pantheratigrisjacksoni) is a critically endangered species native to the Malaysian Peninsula. To imitate wild conditions where tigers do not hunt every day, numerous wildlife sanctuaries feed their daily. However, effects of fasting on gut microbiota captive remains unknown. This study aimed characterise by comparing microbial communities during versus normal feeding conditions. was conducted at Melaka Zoo, Peninsula and involved fasted Monday. In total, ten faecal samples...
Understanding dietary diversity is a fundamental task in the study of stump-tailed macaque, Macaca arctoides its natural habitat. However, direct feeding observation and morphological identification using fecal samples are not effective nearly impossible to obtain habitats because this species sensitive human presence. As ecological methods challenging time-consuming, DNA metabarcoding offers more powerful assessment diet. We used chloroplast tRNL approach identify plants consumed by...
Genetic analysis of historical museum collections presents an opportunity to clarify the evolutionary history understudied primate groups, improve taxonomic inferences, and inform conservation efforts. Among most slow pygmy lorises (genera Nycticebus Xanthonycticebus) are nocturnal strepsirrhines found in South Southeast Asia. Previous molecular studies have supported five species, but using morphological data suggest existence at least nine species. We sequenced four mitochondrial loci,...

Flying fox (Pteropushypomelanus) belongs to the frugivorous bats, which play a crucial role in maintaining proper functioning of an ecosystem and conservation environment. Bats are well-known carriers pathogenic viruses, such as BatCov RaTG13 from coronavirus family that share 90.55% with SARS-CoV-2, pathogen causing recent global pandemic disease 19 (COVID-19). However, bats' possible carrier bacteria is less explored. Here, using metabarcoding analysis through high-throughput sequencing,...
Human–elephant conflict (HEC) contributes to the increasing death of Asian elephants due road accidents, retaliatory killings and fatal infections from being trapped in snares. Understanding diet throughout Peninsular Malaysia remains crucial improve their habitat quality reduce scenarios HEC. DNA metabarcoding allows investigating animals without direct observation, especially risky areas. The aim this study was determine: i) wild HEC areas using ii) influence distinct environmental...
The world's largest terrestrial mammal, Asian elephants, are known to have enormous feeding needs. Several factors such as season, sex, age, and daily activities influence the amount of food required by an individual. Generally, captive elephants a limited choice on basis compared with that in wild. Elephants captivity fed according prepared schedule, whereas wild free choose type plants they consume their natural habitat. In past, ecological observations been widely used determine diet...
Siamangs ( Symphalangus syndactylus ) are native to Peninsular Malaysia, Sumatra and southern Thailand their taxonomical classification at subspecies level remains unclear. Morphologically, two were proposed as early 1908 by Thomas namely s. continentis. Thus, this study aims clarify the Siamang status, based on mtDNA D -loop sequences. Faecal samples collected from wild populations different localities in Malaysia. A 600-bp sequence of mitochondrial region was amplified faecal DNA extracts...
