Different habitat structures occupies different composition of anurans species which can be useful in determining their specific habitat requirements and preferences. The study assessed anurans species composition and diversity along an elevational gradient of Balinsasayao Twin Lakes Natural Park, Negros Oriental, Philippines. A line transect (1km)...

... corrugatus ( Fig. 2A) and Platymantis hazelae (Fig. 2F) found in the submontane along the lake were bigger compared to the same species found in the other sites (Table 2). This could probably be that the species was affected by the change in temperature between sites that considerably altered the microhabitat of the anurans. ...Citations
... This study focuses on the Negros region, home to some island endemic tetrigids (Hebard 1923;Cigliano et al. 2017). One of the important protected forest and mountainous areas in Negros Island is the Balinsasayao Twin Lakes Natural Park (BTLNP) -a declared protected area due to its many endemic and threatened species of flora and fauna (Dolino et al. 2004;Aureo et al. 2019Aureo et al. , 2021. BTLNP is one of the Philippines' long-term ecological research sites (LTERs). ...
Paraspartolus Günther, 1939 is a monotypic genus endemic to the Philippines. Its only species-P. curiosus Günther, 1939-has been known only from Cape Engaño, Santa Ana, Cagayan, Luzon Island. Even though the species was described more than 80 years ago, only three specimens have been known, and nothing about the species' coloration, variability, or ecology was noted. In this study, we provide live photographs of the species for the first time from Negros Island-some 1000 km away from the type locality. We present detailed measurements of the collected male and female specimens and describe the species' color variations and microhabitats, including their bryophyte associates. We provide comments on the distribution of the species and identify problems with the higher classification.
Balinsasayao Twin Lakes Natural Park (BTLNP) is one of the protected areas on the Island of Negros Oriental which is enormously rich in biodiversity due to different Lowland types formed along its elevation gradient. This study was conducted to better understand the composition and diversity of plant species in the natural park to improve conservation and management efforts of these remaining forests which are currently under threat from eco-tourism and other anthropomorphic influences. Within the 18 randomly distributed nested plots, a total of 351 species of plants were recorded. Of these, 183 species were trees, 54 herbs, 51 shrubs, 41 pteridophytes and 22 vines. The result of hierarchical cluster analysis showed differences in plant composition along the elevation gradient. There were 30 (9%) threatened species (vulnerable, endangered and critically endangered) and most of which were found in the submontane Lowland. Furthermore, the species diversity increases from lowland to sub-montane and eventually decreases towards montane Lowland. These results not only indicate the importance of BTLNP, but also highlights the submontane as a special area of concern due to the higher concentration of threatened and endemic species.
