Anurans in forests near cities in Peninsular Malaysia and Malaysian Borneo reflect the impact of 47 years of habitat disturbance on species’ diversity and relative fitness
Description
The datasets include species occurrence and biodiversity data of anuran records from two geographically distinct forests: Ayer Hitam Forest Reserve (AHFR) in Peninsular Malaysia and Universiti Putra Malaysia Bintulu Campus (UPMBC) in Malaysian Borneo.This datasets provides valuable insights into species distribution, habitat preferences, and the effects of human disturbance on anuran populations in both forest near cities. 1. A total of 466 individuals from 39 species (6 families) in AHFR and 95 individuals from 24 species (7 families) in UPMBC. 2. Long-term species records: Historical data (1975–1999) integrated with multi-year surveys (2015–2019) in AHFR and a four-year survey (2005–2009) in UPMBC. 3. Sampling and environmental data included zones in AHFR categorized by disturbance level: protected, minimally disturbed, controlled, moderately disturbed, and disturbed. The UPMBC sampling zones categorised by planted forest, Nirwana Reserve Forest and campus forest. 4. methods of surveys for anurans within both forests using nocturnal line transect surveys along trails and streams and quadrat sampling for forest floor species inventory. 5. Morphometric dataset composed of measurements of snout-vent length (SVL), tibia length (TL), and body condition index (BCI) for various species. 6. Comparative analysis of body size and condition between disturbed and protected zones in AHFR. 7. Interspecific comparisons of morphometric traits, focusing on Limnonectes ibanorum populations in AHFR and UPMBC. 8. Statistical and analytical methods include: (i) PCA (Principal Component Analysis) for morphological trait correlations. (ii) Regression-based body condition index calculation due to missing weight data. (iii) Diversity indices to assess species richness, evenness, and abundance across zones.
