Abstract

Bondowoso located in a valley of Raung mountain roots in East Java, Indonesia. The eruption of Mt. Raung in 2015 not only cause loss of life, but also underlining the fact of unusual Snake Bite Cases (SBC), as recorded in the dr. Koesnadi Hospital. We conducted a thorough analysis of the SBC in 2015 along with the survey on all the incident location in January to March 2016. This study represented an improvement on the population of venomous snake in the agriculture area, and reached the highest peak before the eruption. The presence of continuous vegetation at the edge of watersheds become green corridor that functioned as the movement track for snakes in order to avoid the volcano effect.

Abstract

Indonesia is known as one of the highest supplier on animal illegal trading, especially reptile. The objectives of this study are to reveal the preparation proccess of reptiles in the wholesaler and the flow of illegal trade through deep interview and observation in Kebumen Regency, Central Java, Indonesia. The results showed that wholesaler did some specific processes towards reptile. As much as 289 reptiles were observed to be traded in various conditions. Dry season affect the amount of animal sold. Chinese Ratsnake (Ptyas korros) and Reticulated Python (Malayopython reticulatis) became the most traded commodity within reptile trading, and is reported to be exported to other countries. Trafficking of adult reptiles could threaten their wild population, yet the level of exploration and monitoring toward reptile’s wild population are still low.Keywords: Kebumen, reptile, trade, population, wholesaler

Abstract

The habitat destruction and land-use changes caused the decline of animal composition in many tropical regions. Here, we study the diversity of herpetofauna in the lowland areas in Sumatera Barat, a midwestern province in Sumatera island, using a visual encounter survey method. The surveyed habitat included rubber plantations, streams, paddy fields, and peat swamps. We observed 338 individuals representing 44 species from 14 families of herpetofauna with almost 90% individuals were amphibians. Overall, the rubber plantations contained a higher number of species than other types of habitat. For amphibians, Ranidae and Dicroglossidae represented the first and the second highest both in the species and individual number. For reptiles, Agamidae and Colubridae or Gekkonidae accounted for the first and the second highest in the individual number while Colubridae and Scincidae consisted of the highest species number. Our data showed that the diversity index was mostly in moderate level except in paddy field. The species composition in rubber plantations were more similar to those of streams rather than paddy field or peat swamp Sago habitat.

Abstract

This paper discusses a predator-prey stage structure model for two predators and two preys with Monod Haldane and cannibalism response functions that describe the interactions between populations of young prey, adult prey, young predator, and adult predator. In this model it is assumed that only adult predators are capable of attacking to consume young predators, only adult prey are capable of reproduction, there is a Monod-Haldane effect describing the phenomenon of group defense where predation is reduced, or even prevented altogether, because the ability increases from prey for further defense or camouflage when their numbers are large enough. Dynamic analysis is carried out by determining the equilibrium point and its existence conditions and analyzing the local stability of the equilibrium point. The predator-prey model has three equilibrium points, namely the trivial equilibrium point, the prey free equilibrium point and an interior point that exists under certain conditions. The equilibrium points is locally asymptotically stable under certain conditions. The results of the numerical simulations show suitability with the results of dynamic analysis.

Abstract

Gunung Sigogor Nature Reserve is a conservation forest administratively located in Ngebel District, Ponorogo Regency, East Java, Indonesia. The dragonfly and damselfly community structure, which includes diversity, abundance, evenness and dominance, can be used as an early indicator of changes in environmental conditions, especially in aquatic ecosystems. This study aimed to determine dragonfly and damselfly’s community structure, diversity, evenness, dominance, and habitat preference. This study uses the Visual Encounter Survey (VES) observation and transect methods. This method is carried out by tracing all predetermined observation stations by recording the diversity of dragonfly species and counting the number of individuals. The study conducted in the Gunung Sigogor Nature Reserve area showed 15 species from 8 families consisting of 9 species of Suborder Anisoptera and six species of Suborder Zygoptera. In the results, the highest diversity index value was in the Small Stream (S3) with H'= 1.84. The evenness index, Goa Jepang Stream (S5), has the highest value with a value of E=0.9, and the dominance index of Watu Bandar Stream (S6) location has the highest value with a value of C=1.

Abstract

Gunung Picis and Gunung Sigogor nature reserves, located in the Wilis mountain range of East Java, were established in 1924 and 1936, respectively. These areas are critical for biodiversity preservation as mandated by Indonesia's Law No. 5 of 1990 on Conservation of Biological Resources and Ecosystems. Despite previous surveys documenting various mammals, birds, reptiles, and amphibians data remain limited. Herpetofauna, particularly amphibians, are vital bio-indicators due to their sensitivity to environmental changes, but they face significant threats from habitat loss and exploitation. This study, conducted in November 2020 using Visual Encounter Surveys and opportunistic searches, aimed to catalog herpetofauna diversity in these reserves. The survey identified 29 herpetofauna species, with Nyctixalus margaritifer rediscovered at a new site. Most species were classified as Least Concern (LC), except for the Gonocephalus kuhlii (Vulnerable/VU), indicating potential habitat threats. Analysis of species distribution highlighted "Wates stream" as the most diverse habitat. These findings provide a critical foundation for future conservation efforts, emphasizing the need for targeted strategies to protect amphibian and reptile species in Gunung Picis and Gunung Sigogor nature reserve.

Abstract

Bird vocalizations are crucial for communication and adaptation to environmental changes. As forests are converted to agriculture, agroforestry plays a key role in conserving biodiversity. This study examines vocal bandwidth variations in four bird species-Common Tailorbird (Orthotomus sutorius), Sooty-headed Bulbul (Pycnonotus aurigaster), Olive-backed Sunbird (Cinnyris jugularis), and Small Minivet (Pericrocotus cinnamomeus)-across three coffee agroforestry sites in Jember, Indonesia: Silo, Kluncing, and Kaliwining. The study explores how vegetation structure influences vocal adaptations using sound recordings, vegetation surveys, the Kruskal-Wallis test, and Pearson correlation analysis. Results show significant vocal bandwidth differences in Common Tailorbird and Sooty-headed Bulbul. Common Tailorbird exhibited the highest bandwidth variation in Silo (2.85 kHz), followed by Kluncing (2.30 kHz) and Kaliwining (1.10 kHz) (p<0.001). Similarly, Sooty-headed Bulbul showed significant variation, with the highest bandwidth in Silo (3.1 kHz), Kaliwining (3.5 kHz), and Kluncing (2.7 kHz) (p<0.001). However, bandwidth variation in Olive-backed Sunbird (p = 0.12) and Small Minivet (p = 0.0014) was not significant. Pearson correlation analysis indicated a strong but non-significant relationship between vegetation structure (Importance Value Index) and Sooty-headed Bulbul presence (R² = 0.8999, p = 0.059). These findings suggest that while vegetation influences some species, other factors like resource availability or human activity may also shape vocal adaptations. This study enhances understanding of bird communication in agroforestry, supporting biodiversity conservation and sustainable land management.

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.
