“…This also elucidates their absence in hilly regions where the stream beds consist mostly of pebbles and rocks that possibly will not serve as good refuge grounds. Hossain et al (2008) reported that marshlands and agricultural fields were the most preferred habitats of L. punctata, followed by ponds, streams, and lakes. On the contrary, M. trijuga preferred streams (30.11%), agricultural lands (26.7%), and ponds (22.16%) followed by wetlands (6.81%), rivers (5.68%), drainages (2.84%), and gardens (1.14%).…”

Freshwater turtles symbolize a key component of biodiversity in aquatic ecosystems. Of the 356 living species of turtles and tortoises in the world, 34 species are recorded from India. The number of freshwater turtle and tortoise species found in the state of Goa, however, is debatable. No study specific to the Goa region has been carried out on freshwater turtles. Therefore, baseline data on diversity and distribution of freshwater turtles is scanty. The present study was conducted to address this lacuna in knowledge, which will further aid in identifying threats to the population of freshwater turtles and in devising appropriate methods for their conservation. The diversity and distribution of freshwater turtles was investigated in 186 sites in Goa from June 2012 to May 2015. A total of 337 specimens of two native and one introduced species of freshwater turtles belonging to three families—Trionychidae (Indian Flap-shell Turtle Lissemys puncata), Geomydidae (Indian Black Turtle Melanochelys trijuga) and Emydidae (Red-eared Slider Trachemys scripta elegans)— were identified. Melanochelys trijuga (52.23%) was the most widely and abundantly distributed species, and was recorded from 132 sites. L. punctata (46.88%) was recorded from 113 sites, while T. scripta elegans (0.89%) was rare and was recorded from only two sites. While Melanochelys trijuga is generalized in habitat selection, making it the widely distributed species in the State of Goa, L. punctata is more specific in habitat selection thus restricting its range to coastal, middle-level plateau and the foothills of Western Ghats.

“…The Indian Flapshell Turtle (Lissemys punctata) is a softshelled turtle that is widely distributed across the Indian Subcontinent, where it inhabits habitats that include metropolitan, agricultural, and natural aquatic systems (Das 1991;Moll and Moll 2004;Hossain et al 2008;Krishnakumar et al 2009). Lissemys punctata is known to move through terrestrial areas during drought conditions and monsoons due to suboptimal water levels (Bhupathy et al 2014).…”

“…Freshwater turtles in muddy environments, medium-size rivers, dams, and ponds are considered as water purifiers as it contributes to the reduction of algal bloom and are indicators of pollution [4, 23,28,36]. Soft-shell turtles are a useful source of protein [11,17,37] and used for purifying blood and cure respiratory diseases and intestinal disorders [13,24]. Several factors such as habitat fragmentation, pollution, introduction of exotic species, hunting, and global climate change affect the biodiversity of turtle fauna [5,9,19,21,22].…”

Background: The turtle population plays an important role in sustaining the water ecosystem by minimizing pollution from water. The identification and molecular investigation of freshwater fauna is essential for conservation of the species that are near to extinction. The quality of water, type of flora, fauna, and environmental condition are the major factors that directly affect the distribution of freshwater turtles. Studies on the species diversity and habitat of freshwater turtle have not been focused previously in the region. The present study was the first conducted to estimate the habitat and genetic diversity of freshwater turtles using 12S rRNA (ribosomal RNA) gene in Pakistan.Materials, Methods & Results: A total of 26 samples were collected from various localities using hand net, cast net, gills net, steel hooks, thick chemical wire, using chicken intestine and small fishes. The collected turtle specimens were morpho-taxonomically categorized into two genera, Lissemys punctata andersoni (n=13, 50%) and Nilssonia gangetica (n=13, 50%). The collected species showed an aggressive and active behavior in captivity during summer. Genomic DNA was extracted from collected specimens and used in PCR reaction by using specific primers for the amplification of short fragments of 12S rRNA gene. Analysis of generated sequences confirmed the existence of L. p. andersoni in the region. The generated sequences of L. p. andersoni correspond to Clad A and showed a close resemblance among different species of the genus Lissemys.Discussion: This study is the first investigation about the habitat and of the endemic turtle species L. p. andersoni and N. gangetica in Pakistan. The genetic identification followed by phylogenetic analysis based on 12S rRNA partial genes revealed a closest similarity with the sequences generated for the same species from the neighboring countries. This study provided information to conduct further molecular studies that are essential to provide significant genetic data about turtle species.Keywords: turtle, ecology, diversity, phylogeny, Pakistan.
