“…Sampling was carried out in both the core and buffer areas of DTR between July 2020 and November 2022. Extensive surveys were carried out in different seasons and habitat types using multiple approaches such as trail walks, line transect surveys and road surveys by a group of two-four individual researchers (Prasad et al 2018). Different gradients of fallow lands and secondary forested areas (community forest) were also surveyed.…”

Herpetofauna is an important group of vertebrates with key functions in ecosystem sustenance. Nonetheless, with ever-increasing anthropogenic activities and lack of evidence-based studies, about 80% of the herpetofauna diversity of southern Asian region is threatened. Our study reports 80 herpetofauna species distributed across different habitat types in Dampa Tiger Reserve (DTR), Mizoram. We revise the amphibian list of DTR throughthe addition of seven species and establish the identity of cryptic species such as Microhyla ornata which is actually two distinct species,i.e., M. mukhlesuri and M. mymensinghensis. Through the questionnaire survey, it was found that 90% of the respondents depended on varied forms of forest resources. Herpetofaunal species account for 30% of the faunal resources with Varanus bengalensis, Ophiophagus hannah, and Python bivittatus being the most consumed reptile species. All chelonians and some amphibians like Duttaphrynus melanostictus, Pterorana khare, Hoplobatrachus tigerinus, Hoplobatrachus litoralis, Hydrophylax leptoglossa, Minervarya asmati, Polypedates teraiensis, and Sylvirana lacrima were also found to be consumed and used for their presumed medicinal values. In addition to hunting, road-kills, use of chemical pesticides, and habitat alteration were recorded to be the prominent threats in the region. The land use and land cover (LULC) data shows a steady recovery of dense forest and a better forest fire scenario as over 90% of the DTR core region falls in the ‘low severity’ and ‘unburned’ category. With continuous alteration in forested areas, the present study will not only provide a fundamental baseline for the conservation of herpetofauna and better management of protected areas but also stimulate future herpetological-based research.

“…Delhi, the national capital territory of India is the second most populated city in the world and is known for its greenery with around 22% green cover 12 . It is surrounded by agricultural farms, ridges, and other green areas and experiences regular snake occurrences in residential, recreational, educational, and industrial areas 10 . Unfortunately, snakes in Delhi have never received priority as compared to the other groups like mammals and avian fauna, therefore, no significant studies have been published on the occurrence of snakes in Delhi 13 .…”

Delhi, the capital city of India is, highly urbanized and surrounded by remnant forest, farms, ridges, and other green areas experience regular snake encounters in and around residential, institutional, and industrial areas. A total of 41 months of sampling from January 2019 to May 2022 was conducted wherein we, studied the snake assemblage in Delhi to determine the species composition, encounter frequency, seasonal activity patterns, and probable encounter sites in an urban setup. We documented 372 individuals belonging to 15 species from seven families out of 23 species found in Delhi. Snakes were found inside forests, public parks, homes, drain networks, streets, office buildings, and even in school-college buildings. The most recorded species being Ptyas mucosa (37.37%, n = 139), Naja naja (19.62%, n = 73), and Lycodon aulicus (13.44%, n = 50). The highest numbers of incidents were reported in the month of July (22.04%, n = 82) and August (19.89%, n = 74) during the peak monsoon season, for identifying high encounter sites, we used a geostatistical modeling tool, Ordinary kriging to identify places having more snake occurrences. We further used a statistical spatial method called average nearest neighbor distance to detect the pattern distribution of snake species. Spatial interpolation done through Ordinary kriging highlighted two areas having concentrated snake encounters. The results of the average nearest neighbor distance analysis showed three species having clustered and two species having dispersed distribution. The incidence of snake encounters was found to be highly seasonal and appeared to be associated mainly with monthly rainfall, temperature, and humidity. The findings of this study on snakes’ distribution patterns provide valuable insights into the conservation of these species. Understanding their habitat preferences and spatial distribution is crucial for the implementation of effective conservation strategies.

“…Ecuador is home to a particular diversity of amphibians and reptiles and is intersected by two pivotal biodiversity hotspots in South America: the Tumbes-Chocó-Magdalena and Tropical Andes regions, fostering elevated levels of diversity and endemism (Myers et al 2000). Amphibians and reptiles serve as crucial ecosystem health indicators, reflecting environmental stressors and playing fundamental roles in the food chain, bridging aquatic and terrestrial ecosystems (Steinke 2016;Prasad et al 2018).…”

We present notable distributional updates for 13 species from western Ecuador (six anfibians and seven reptiles). Our findings include the northernmost confirmed sighting of Pristimantis kuri (Yánez-Muñoz et al. 2016) and the southernmost documented appearance of Imantodes inornatus (Boulenger 1896) and Lepidoblepharis buchwaldi (Werner 1910). Additionally, we document new records and notes of distribution range of Agalychnis spurrelli (Boulenger 1913), Hyloscirtus alytolylax (Duellman 1972), Engystomops montubio (Ron et al. 2004), Pristimantis nyctophylax (Lynch 1976), Pristimantis walkeri (Lynch 1974), Chironius flavopictus (Werner 1909), Chironius grandisquamis (Peters 1869), Dendrophidion graciliverpa (Cadle 2012), Ninia atrata (Hallowell 1845), and Urotheca fulviceps (Cope 1886). These observations significantly contribute to filling information gaps in our understanding of these species’ distributions. The data, derived from samples collected across diverse forested areas in the western region of Ecuador (provinces of Cañar, Guayas, El Oro, and Los Rios), provide valuable insights into the ecology and conservation of these species.
