This study attempts to evaluate the effect of different socio-environmental variables on the proliferation of rats and Leptospira in suburban areas of Dungun, Terengganu, Malaysia. We performed ten trapping sessions between April 2021 and January 2022, and captured 89 rodents from five species during the study. We tested the captured animals forLeptospira bacteria using PCR detection

Biodiversitas 23: 5574-5584. Malaysia has various ecosystems, including mangrove forests, that can support a rich number of amphibians and reptiles. However, amphibians and reptiles remain understudied, especially in mangrove forests. The main objective of this study was to determine the diversity of amphibians and reptiles in the mangrove forest of Sungai Kerteh. The sampling was conducted from 19th until 21st August 2019 by using the Visual Encounter Survey (VES) method along 2 km2 area of Sungai Kerteh. A total of 53 individuals were recorded belonging to 12 species (5 amphibian species and 7 reptile species). For amphibians, three families were recorded, with the family Dicroglossidae being the most abundant, with 13 individuals. For reptiles, eight families were recorded with the family Agamidae being the most abundant with 18 individuals. Fejervarya cancrivora (11 individuals; Family Dicroglossidae) was the most abundant amphibian species, while Leiolepis belliana (14 individuals; Family Agamidae) was the most abundant reptile species. There was no significant difference between the diversity of reptiles (H’: 1.6975) and amphibians (H’: 1.2643) (t: -1.6835, p>0.05). This study provides the first checklist of amphibians and reptiles species that will be helpful in identifying existing herpetofauna species and possible endangered or rare species in the Sungai Kerteh mangrove forest, which will help contribute to the conservation efforts of the herpetofauna in this area.

This data article presents the composition of selected physico-chemical water parameters, phytoplankton, flora and fauna in Sungai Kertih, Terengganu, Malaysia. Sungai Kertih is surrounded by mangrove forest and located nearby to a coastal hill namely Bukit Labohan that supports vast biological resources to its adjacent inhabitants. Therefore, a biodiversity and environmental assessment was conducted in Sungai Kertih from 19-21 August 2019 to document the biodiversity and physico-chemical water parameters of the river. The dataset show that Sungai Kertih is occupied by 14 tree mangrove species, 43 phytoplankton species, 21 bivalve species, 10 crustacean species, five amphibian species and eight reptilian species. The obtained physico-chemicals water parameters data were the value of pH, total dissolved solids, dissolved oxygen, temperature, salinity and electrical conductivity. Understanding the influence of physical and chemical properties on biological resources in coastal ecosystem is one of important in river conservation and management practices. Thus, this baseline dataset can be utilized for further reference and monitoring the health of the environment in the mangrove ecosystem.
