This study investigates the impact of human-modified habitats on anxiety and stress-related behaviors in Trachypithecus pileatus (capped langur) in Bangladesh. Behavioral indicators such as self-directed behaviors (scratching, self-grooming, body shaking) and vigilance types (induced and routine) were analyzed. Results suggest that while some behav...

Bangladesh shelters a very rich and diverse avifauna. Anthropogenic activities have a global impact on avifauna, particularly in Bangladesh, where human disturbances and unplanned urbanization can lead to the decline of this particular taxon. A direct observation-based study was conducted to investigate the avian community structure in Daudkandi Up...

Nowadays urbanization continues and poses a serious threat to wildlife globally. A survey-based study on wildlife was conducted for three years from March 2017 to February 2020 in Dhaka University campus. Data was collected through direct visual encounter observations. A total of 94 species of wildlife under 20 orders and 52 families were observed....

Species diversity is an important parameter for monitoring ecology that can accelerate conservation planning. A study on the diversity, composition, and distribution of the herpetofauna in four districts of northwestern Bangladesh was conducted through direct field observations and plot counting during day and night from April 2017 to March 2018. A...

People from different socioeconomic status show different attitudes toward herpetofauna. A study was conducted to investigate local people's perceptions and attitudes toward herpetofauna in four northwestern districts of Bangladesh. Data were collected through a structured questionnaire survey among 236 randomly selected people. Animals were divide...

Urban environments harbour many species of wildlife. Such environments may provide a wide range of benefits, although these species could also face more threats in them than outside of the cities, without proper consideration. A comprehensive study of the wildlife in Dhaka, a megacity of Bangladesh, was conducted from September 2015 to November 201...

We studied the feeding ecology of hatchling and juvenile Northern River Terrapin (Batagur baska) from April 2017 to April 2018 in captivity in Bangladesh. We made direct observations daily after providing foods in the late morning around 0930. We weighed food before and after the feeding season to measure the amount of food intake. We also obtained...

Global amphibian populations are facing a novel threat, chytridiomycosis, caused by the fungus Batrachochytrium dendrobatidis (Bd), which is responsible for the severe decline of a number of species across several continents. Chytridiomycosis in Asia is a relatively recent discovery yet there have been no reports on Bd-presence in Bangladeshi amphi...

Volume 30 (April 2020), 99-111 Published by the British Herpetological Society We conducted a systematic review to evaluate the knowledge base for amphibian chytrid Batrachochytrium dendrobatidis (Bd) infection in the continent of Asia. Despite an indication of geographic bias in terms of studying chytrid fungus distribution in Asia, 167 amphibian...

Herpetofaunal species in Bangladesh are getting attention nowadays focusing conservation mainly in protected areas. Most of the recent herpetofaunal discovery is from non-protected areas of Bangladesh but management and conservation approaches are ignored in these areas. Therefore, a study was conducted on diversity, composition and distribution of...

Hemidactylus is a taxonomically complex genus and little is known about its feeding and breeding behavior in Bangladesh. Most of the species of this genus have a preference to live within human habitations, and play an important role in ecosystem, controlling insect pest population. Their breeding strategy is almost similar with each other and asso...

Amphibians, like some animals and plants, defend themselves against various pathogenic organisms by producing and secreting various peptides and small molecules from granular skin glands. In this study, we evaluated for the first time, the antibiotic activity of the skin secretions of 8 different frog species (Euphlyctis cyanophlyctis, E. hexadacty...

An unusual gynandromorphic individual of Neurothemis tullia is reported from Faridpur District in Bangladesh. The head and thorax, including wings, are clearly bilaterally gynandromorphic. The abdomen is entirely pruinose androchromic with very few light spots left, however the abdominal tip bears female appendages. This unusual combination of gyna...

Wildlife diversity (amphibians, reptiles, birds and mammals) of Kashimpur Union in Gazipur Sadar Upazila under Gazipur district was studied from May, 2015 to March, 2016. A total of 110 species of wildlife belonging to 58 families under 19 orders were recorded. Among them, 6 (5.45%) species were amphibians, 14 (12.72%) reptiles, 72 (65.45%) birds a...

Uperodon globulosus (Günther, 1864) has so far been recorded from 6 localities in Bangladesh over the past 3 decades. In June 2017, we found an adult female in a courtyard of a house in Jonail village (Natore district, Rajshahi division, Ban-gladesh), which is approximately 102 km southwest of the previous nearest previously known occurrence of thi...

The Northern Plains sacred langurs are characterized by their ability to adapt to a variety of habitats. We compared activity budgets of two langur groups, one living in the rural area and the other in the center of Keshabpur town. Data was collected from September, 2012 to August, 2013 through continuous focal animal sampling. Types of different f...

Substrate utilization by Bengal sacred langur (Semnopithecus entellus) was studied from September, 2012 to August, 2013 in Jessore, Bangladesh. The study was based on direct observation from dawn to dusk and data was collected using focal animal sampling. The results showed that Bengal sacred langur is not totally arboreal or ground dwellers but th...

An extensive study was conducted on food consumption and feeding behavior of saltwater crocodile (Crocodylus porosus) in the Reptiles Farm Ltd. (RFL) located at Hatiber village, Bhaluka, Mymensingh. The study was mainly based on direct observation and previous data collected by the technicians of the RFL. Average temperature (0C) in the farm area w...

The study was carried out through direct field observation by plot counting; transect line method and interviewing the local people from September 2011 to March 2012. A total of 83 species of wildlife belonging to 18 orders, 34 families and 64 genera was recorded. Of them, 4 (4.82%) species were amphibians, 17 (20.48%) reptiles, 55 (66.27%) birds a...
