Jalthal Forest (. km ) is a remnant forest patch of a once continuous, lush and dense area of sal Shorea robusta and mixed deciduous vegetation in eastern lowland Nepal that is now surrounded by a dense human population. The forest is one of the last remnants of suitable habitat for the Critically Endangered yellow-headed tortoise Indotestudo e...

Colonial nesting waterbirds in agricultural landscapes have historically received limited research attention, especially in South Asia. For example, the Asian openbill (Anastomus oscitans) is a colonial species that extensively utilizes agricultural landscapes, yet there is a notable lack of substantial studies despite increasing urbanization acros...

Simple Summary The taxonomy of the sinica group of macaques has been unresolved due to inconsistencies between their physical traits and genetic relationships. To clarify this taxonomic issue, we analyzed DNA from previously unsampled populations of the macaques in the Himalayas. Our results revealed that the sinica group consists of seven distinct...

Globally, urban expansion has led to habitat fragmentation and altered resource availability, thus posing significant challenges for wildlife. The Chinese pangolin (Manis pentadactyla) is a critically endangered species experiencing population decline due to illegal trade and habitat degradation. This study analyzed variables affecting habitat occu...

Once widespread throughout the tropical forests of the Indian Subcontinent, the sloth bears have suffered a rapid range collapse and local extirpations in the recent decades. A significant portion of their current distribution range is situated outside of the protected areas (PAs). These unprotected sloth bear populations are under tremendous human...

This booklet provides an introduction to the turtles and tortoises of Nepal. It includes information on their general evolutionary history, distribution, ecology, and conservation challenges, highlighting 12 species in the Nepali language. The aim of the booklet is to provide general information about turtles, their ecological role, and the necessi...

The Indian flying fox, Pteropus medius is a fruit bat that contributes significantly to seed dispersal and pollination services. These bats face serious threats from the loss of roosting trees due to urbanization and deforestation. This study aimed to assess the roost characteristics of Indian flying foxes and the effects of anthropogenic noise on...

The Assamese macaque (Macaca assamensis) population in Nepal is one of the least studied mammals. It is legally protected by the National Parks and Wildlife Conservation Act 1973; however, its population status, distribution and conservation threats are ill-documented. The species is thought to have a disjunct distribution having limited informatio...

The non-native vermiculated sailfin catfish Pterygoplichthys disjunctivus (Weber, 1991) is recorded for the first time in eastern Nepal's aquatic systems. Native to South America, the first reports of P. disjunctivus in Asia were recorded in India, with subsequent reports from Bangladesh, Hongkong, Indonesia, Malaysia, Singapore, Thailand and Vietn...

The Stinging catfish (Heteropnuestes nani) was described in 2013 from the Noakhali of Bangladesh through detailed morphological characterization. They differ significantly from their congeners based on small size, completely separated pectoral spine from rays bearing 9–10 serrae along the inner edge and united anal-caudal fin. In Nepal, only one sp...

Nutrition plays a crucial role in avian development, growth, and health. Inadequate nutrition can have an impact on immune systems and increase susceptibility to diseases. However, there is a paucity of studies that quantify the nutrition provided to young birds. We studied the nutrients delivered to six nests, especially to the hatchling and nestl...

Monitoring the impact of fishing pressure on the Singhiya River is critical for resource development and sustainability, and the present situation is alarming and causing critical concern among the public. This study aimed to identify fish community trends over time and space in the river, and to investigate the impact of environmental variables on...

In 2016, Amblyceps waikhomi from the Brahmaputra drainage of Arunachal Pradesh, India, was described. Based on morphometric and meristic characteristics, we report the frst-ever sighting of A. waikhomi from the Singhiya River in Morang district. A deeper body depth at the anus sets the A. waikhomi apart from its congeners. Te river systems of Nepal...

Amidst its successes on various fronts of forest management, there are still concerns about overall biodiversity outcomes in community forests (CFs) of Nepal. The potential for biodiversity conservation is undermined by an orthodox focus of conservation efforts on protected areas and charismatic species, and the prevalence of management activities...

Understanding habitat characteristics and utilization patterns of Chinese Pangolins (Manis pentadactyla) in urban environments are critical for instigating strategic conservation efforts. As pangolins are among the most trafficked mammal in Nepal with very scarce knowledge on their ecology and distribution: this study aims to identify habitat use a...

Proper understanding regarding the status and threats to avian diversity is a key to formulating an effective conservation-dependent species management strategy. This study aims to assess the bird species status, distribution, and associated threats in East Nepal’s Dharan sub-metropolitan city. Based on habitat suitability, vegetation, altitude, an...

The present study was conducted in 28 spots of 10 sampling sites including forest and urban areas of northern part of Dharan, Sunsari District (26.7944° N, 87.2817° E, 349 m msl) and its vicinities in the Province No. 1 of Nepal. The scan sampling method was applied to count the monkey population and their menace was surveyed through the questionna...

The large wading colonial breeder bird, the Asian Openbill is considered as a nationally vulnerable species and only a few studies regarding the population distribution of Asian Openbill have been studied so far. The main aim of this research is to address the population status and nesting habitat selection of Asian Openbill in the lowlands of east...

Santhal or Satar community is a unique ethnic group of eastern Nepal. Despite the small population (0.19 % of the total population of the country), they have rich cultural and hunting practices. This study conducted in Jhapa district, which lies in Province No. 1 of eastern Nepal. The present study helps to describe the traditional hunting tools wi...
