Abstract

The population of herpetofauna (Class: Reptilia, Amphibia) is continuously declining throughout the world. Moreover, habitat changes such deforestation drive rapidly to declining process. Human communities play an important role in conserving the herpetofauna by maintaining and improving the harmonious relationship between human and environment. Therefore, these association will strongly support the conservation of herpetofauna and their habitats. This study is aimed to survey the herpetofauna communities, explore the local people perspective on herpetofauna, and the relationship between human and herpetofauna. We found 12 species observed in this survey that included to 3 order of herpetofauna: anura, squamata and testudines. Local people recognized herpetofauna species around them well and do not harm them because of their roles, such as part of nature (39%), bioindicator (33%), myth (17%), and economic value (11%). We also revealed the local knowledge on herpetofauna, as 14 local names and their roles. Despite Kuala Tungkal is a strategic area for the national port development that probably impacts herpetofauna microhabitat, it needs serious attention on herpetofaunal issues.

Abstract

This study investigates the role of coffee agroforestry in sustaining biodiversity and ecosystem functions in Kluncing, Ijen, Indonesia. By quantifying bird, butterfly, and coffee insect diversity using the Shannon-Wiener index, it evaluates ecological dynamics and their implications for sustainable land management. Bird communities demonstrated the highest diversity (2.911), indicating ecosystem stability, while butterflies (2.481) and coffee insects (1.841) exhibited lower diversity, reflecting habitat and resource limitations. Trophic network modeling using NetworkX identified keystone species like Collocalia linchi (21.9% relative abundance) among birds and the Formicidae family (29.8% relative abundance) among coffee insects, emphasizing their critical roles in ecosystem balance. Canonical Correspondence Analysis (CCA) highlighted the influence of environmental factors on species distribution. Species such as Ariadne ariadne and Delias belisama were sensitive to humidity and temperature, while Collocalia linchi favored areas with higher light intensity. The findings underscore the importance of tailored management practices to address species-specific responses to microclimatic variations. Sustainable agroforestry management is vital for preserving biodiversity, maintaining ecosystem stability, and ensuring agricultural productivity. This study also highlights challenges posed by habitat degradation and climate change, emphasizing the need for adaptive strategies to safeguard this unique agroforestry landscape.

Abstract

The fanged frog, Limnonectes kuhlii, exemplifies the complexity of cryptic species. Though originally described from Java, subsequent studies indicate that L. kuhlii encompasses multiple lineages, suggesting the presence of several undescribed species. Suspecting the existence of multiple undescribed species within the L. kuhlii complex in Sumatra, we collected 17 specimens from Java and Sumatra. We extracted the 12S, tRNAval, and 16S mitochondrial DNA from these specimens for phylogenetic analysis using Maximum Likelihood and Bayesian Inference methods and for estimating time divergence. Our findings uncovered two novel diversity within the L. kuhlii complex both in Sumatra and Java. Furthermore, our estimation of time divergence suggests that the diversification of L. kuhlii in Java and Sumatra was influenced by geological and climatic events, including landmass emergence and sea-level fluctuations. In conclusion, our research provides critical insights into the evolutionary complexity and diversity of the L. kuhlii complex in Sumatra and Java. While our molecular evidence suggests novel diversity, further comprehensive morphological studies are imperative to confirm and describe these potential new species. Furthermore, additional sampling across its range and deeper investigations integrating both molecular and morphological data are crucial. Keywords: fanged frogs, Limnonectes kuhlii, Limnonectes sisikdagu, phylogenetics.
