Abstract

The Saurashtra Peninsula, the largest geographical region of Gujarat state, is a prominent place for herpetofauna in the state and recent herpetological explorations have uncovered three new reptilian species from this region. However, fine scale information on the distribution status of amphibians and reptiles, and baseline information about the regional herpetological diversity of many areas of Saurashtra is still lacking. In an attempt to fill the gaps in information, we surveyed the Girnar hill complex of Gujarat state for its herpetofaunal diversity from September, 2016 to August, 2018. In all, 56 species, comprising 10 species of amphibians belonging to 7 genera and 3 families and 46 species of reptiles, belonging to 31 genera and 15 families were recorded; of which, 2 unidentified frog and 2 unidentified lizard species need further taxonomic attention.

Abstract

We re-address the findings of recent publications on herpetofaunal diversity of certain urban areas of Gujarat, India, in which, authors have claimed to report nine frogs and two lizard species for the first time from the State, without any morphological data and/or voucher specimens. We present our critique and comments, with the known distributional ranges of these species and on these erroneous records. We also advocate removal of such species from the faunal list of Gujarat until confirmed reports, based on correctly identified vouchers, are presented. We recommend here that identification of a species should be done following standard protocols and by facilitating the deposition of voucher specimen/s in responsible public repositories for studies involving taxonomy, morphology and range extension.

Abstract

Dinagat Islands hold most of the mineral deposits in the Philippines and have been among the largest mining contributors in the country since 1939. Aside from a massive mining industry, logging is also intensive in this group of islands potentially imperiling its remaining biodiversity. This study primarily aims to determine the species composition of terrestrial vertebrates (amphibians, reptiles, birds, mammals) in two study areas categorized as modified habitats (mining area and logging area) in the Dinagat Islands. These wildlife species are important bio-indicators as they show sensitivity of the species to anthropogenic disturbances. Suitable field survey methods were conducted for the taxa established and a quantitative analysis was performed to determine the diversity and similarity of the species between the study areas. A total of 65 species were identified in the two study areas: 33 species were exclusively identified in the mining area, 49 species were exclusively identified in the logging area, and 17 species were found in both study areas. It should be noted that among the 65 species, 41 species are either endemic to Mindanao and/or the Philippines, and two species were endemic to Dinagat Islands. This study also recorded the newly described coral snake endemic to the island, Calliophis salitan Brown, Smart, Leviton and Smith. This study indicates that although Dinagat Islands is modified by anthropogenic activities, the terrestrial vertebrate species are thriving. Intensive survey in other modified habitats in Dinagat Islands is the next-step forward to take into account existing wildlife to improve conservation decisions, planning and management on the islands.

Abstract

The freshwater ecosystems in Gujarat State, in the western part of India, are important habitats for various freshwater turtles. Due to the lack of information on survival and the morality of the freshwater turtles, we present new information on threats to the the Indian Flap-shelled turtle Lissemys punctata (Bonnaterre) and species mass mortalities observed in some water bodies of the Gujarat State. Approximately 1071 specimens of L. punctata and three specimens of the Ganges Soft-shelled turtle Nilssonia gangetica (Cuvier), along with large numbers of many other species of reptiles and fishes were recorded dead within a span of five years from January 2016 to December 2020. In some of the cases, the circumstantial evidence suggests that entanglement and trapping in fish nets could have been the reason, but large number of the deaths remained mysterious. This mysterious sudden death of aquatic reptiles in various water bodies of the state is of serious concern. We also discuss the possible explanation for these mysterious deaths.

Abstract

A comprehensive record of reptiles found in the Moyar River Valley Landscape (MRVL) is presented in this manuscript. The observations did not adhere to standardized survey methods, and are based on opportunistic encounters during our vegetation survey in different habitats of the MRVL between December 2017 and December 2019. A total of 135 live individuals and 31 road-killed specimens, representing 37 species of reptiles were recorded of which two species are Vulnerable, 13 are Least Concern and 22 species are Not Evaluated in accordance with the criteria of the IUCN Red List of Threatened Species. The recorded species belonged to six families of lizards (Agamidae, Chamaeleonidae, Gekkonidae, Lacertidae, Scincidae, and Varanidae), six families of snakes (Colubridae, Elapidae, Erycidae, Pythonidae, Typhlopidae, and Viperidae), two families of chelonians (Geoemydidae, and Testudinidae), and one family of Crocodylia (Crocodylidae,). The road-killed specimens were recorded between the year 2018 and 2020 and come under Indian Wildlife Protection Act, 1972. Though the present work did not follow a specific survey method, the contribution provides baseline information on the reptile diversity of the MRVL and presents interesting findings from the Sathyamangalam and Mudumalai Tiger Reserves in north-western Tamil Nadu, India.
