Article
Full-text available
Interspecific hybridization occurs almost in all major primate radiations. Intermediate phenotypes, sometimes seen in mixed-species groups, are often the first indications of hybridization. Beyond natural hybridization, human activities, such as habitat fragmentation or population depletion, can be important drivers for initiating or intensifying t...
Article
Full-text available
Diet and home range use patterns provide information on the needs of species faced with changing forest quality. Many primates have diets and foraging strategies that maximize nutrient uptake and minimize energy expenditure, resulting in well-defined home ranges. Primates use their home range in varying ways depending on the spatial distribution of...

Accurately estimating population sizes for free-ranging animals through noninvasive methods, such as camera trap images, remains particularly limited by small datasets. To overcome this, we developed a flexible model for estimating upper limit populations and exemplified it by studying a group-living synanthrope, the long-tailed macaque ( Macaca fa...
Poster
Empirical research indicated that, unlike species with specialized resource requirements, generalist species could potentially experience advantages from habitat destruction and human presence. To understand the impact of such disturbances on habitat generalist and specialized species in a deciduous forest ecosystem, we studied diurnal primate popu...

The Endangered Bengal slow loris, Nycticebus bengalensis is the only nocturnal primate in Bangladesh. Some traditional practices are a major threat to lorisids throughout their range. In Bangladesh, information regarding the interactions between Bengal slow loris and humans is scarce. Using questionnaires, we interviewed 27 individuals in five ethn...
Article
Phayre’s langur (Trachypithecus phayrei) is one of the least-studied Asian colobines. We reviewed a wide range of published and unpublished literature to gather existing information on their taxonomy, distribution, natural history, behavioral ecology, population status, associated threats, extirpations, and knowledge gaps for conservation. This pre...

Full-text available
Agricultural expansion has had a detrimental effect on tropical forests and the animal communities that depend on them. Agroforestry systems, however, with their more complex tree and plant communities, have been shown to be important habitats for a range of globally threatened species, including nocturnal animals. Here, we present novel data on th...

Venomous snakes are one of the most dreadful animals globally that kill their victims by injecting venoms (toxic substances) using fangs. However, snakes are being used for numerous vital life-saving purposes, including antivenom and traditional medicines, pain killers, cancer treatment, cardiac arrest, paralysis, arthritis, anti-ageing, and cosmet...

Tropical forests are threatened worldwide due to deforestation. In South and Southeast Asia, gibbons (Hylobatidae) are important to seed dispersal and forest regeneration. Most gibbons are threatened due to deforestation. We studied the western hoolock gibbon (Hoolock hoolock) in Bangla-desh to determine population size and extent of suitable habit...

Infanticide, the intentional killing of conspecific infants, has been observed widely in mammals, including squirrels. Several ground squirrels revealed this behavioral anomaly, yet no report has been published on the flying squirrels. We report an observation of killing an infant of the particolored flying squirrel (Hylopetes alboniger) by a consp...
Preprint
Tropical forests harbor complex communities that are linked together by biotic relationships. Asian forests in particular have lost many apex predators due to habitat loss. We studied a small forest patch in northeastern Bangladesh, Satchari National Park, to determine density and diversity of nocturnal mammals and evaluate their relationships. Tra...

Bangladeshi chiropteran fauna is poorly studied and there is a lack of complete inventories. A total of 39 species of bats have been reported to occur in the country. Great Woolly Horseshoe Bat Rhinolophus luctus, (Temmick 1834) has been expected to occur in northeast Bangladesh based on its presence in north-eastern India and adjoining areas. Howe...

Raorchestes is a genus of small bush frog characterized by an absence of vomerine teeth, direct development without free swimming larvae, and a transparent gular pouch while calling. During a larger study on canopy fauna in the northeastern region of Bangladesh, five specimens of a small bush frog were collected from Satchari National Park in June...

There is no precise estimation of globally endangered Phayre’s Langur (Trachypithecus phayrei) population in Bangladesh. Published reports revealed a sharp decline of more than 80% population in Bangladesh during the last three generations. So, we surveyed the Langur population in five northeastern forests of Bangladesh since March 2018 to Septembe...

A study entitled ‘Home range and habitat characteristics of Western Hoolock Gibbon (Hoolock hoolock) in Lawachara National Park, Bangladesh’ was conducted from April 2019 to October 2019. A group of Hoolock Gibbon was selected to observe using scan sampling method. Scans were followed at 5 minutes interval to determine the home range size and forag...

Western Hoolock Gibbon (Hoolock hoolock, Harlan, 1834) is the only lesser ape found in Bangladesh that is classified as critically endangered by the IUCN. Their population is declining due to habitat destruction, fragmentation, disturbance, and hunting. We observed a group of gibbons with 4 individuals in Lawachara National Park in northeastern Ban...

Phayre’s Langur (Trachypithecus phayrei) is a globally endangered primate, distributing to south and south-east Asian countries. Fragmentation and destruction of habitats, hunting, inbreeding and local trading are known causes to decline its population. The existing population was reported to be less than 100 individuals in Bangladesh and a decline...

Butterflies are well known to mud-puddle under sunlight.Mud-puddling behavior of butterflies at night was not known. Here, we report an opportunistic observation of mud-puddling behavior of Lethe mekara and Halpe porus butterflies at midnight in a semi-evergreen forest of northeast Bangladesh.This observation is noteworthy enlightening a secret sid...
