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.

Abstract

Cyprinidae is a group of freshwater fish families that has more than 2,420 species that are widespread throughout the world, especially in Central Kalimantan, Indonesia. Wide distribution and the presence of geographic barriers are thought to have an impact on morphological variations in species of the Cyprinidae family. In this study we will provide information on morphological characters on three species of the Cyprinidae family (Osteocillus vittatus, Barbonymus schwanenfeldii, Labiobarbus ocellatus) originating from Central Kalimantan. Data was taken from 3 locations originating from the Kahayan and Rungan river basins, Central Kalimantan. Morphometric measurements were carried out on 14 characters which included total length, head length, tail peduncle length, head length in front of the eyes, standard length, caudal fin length, tail peduncle height, dorsal fin height, body width, eye width and mouth opening width and meristrik in 5 characters which include the number of dorsal fin rays, cloacal fins, ventral fins, pectoral fins and caudal fins. Data analysis was carried out using the Principal Component Analysis (PCA) approach using PAST software. Based on the analysis results, it shows that the three species are morphometrically significantly separated based on the characters that have been measured. This is shown by the location of the species in each quadrant because they have significant differences in character. However, every individual in each species is in the same quadrant because they have similar characters.

Abstract

Butterflies are part of biodiversity that is important to be preserved because the presence of butterflies in an ecosystem, especially forests, is very important, both as part of the food chain, pollinators, and food for other animals. This study aims to analyze the species diversity and abundance of butterflies (Lepidoptera) in the habitat of Tahawa Village Forest Area, Pulang Pisau Regency. The research method used an exploratory survey method with a sweeping technique following a transect line and then calculated Shannon-Wiener Diversity Index (H'), Evenness Index (E), and Species Richness Index (R1). Butterflies found in the Tahawa Village Forest Area consisted of 6 families divided into 15 species with a total of 63 individuals. The most species found came from the Pieridae family and the least from the Geometridae family. The Diversity Index (H') obtained a value of 2.38, classified as moderate diversity. The Evenness Index (E) is in the high category with 0.88, while the Richness Index (R1) is at 3.38 which is still classified as low.

Abstract

Assistance activities for the community, especially the protection and security section of the Tuwung LPHD area, provide a strong basis for improving village forest management, by identifying problems and challenges faced before and after activities, as well as real data on regional potential including fauna inventory and existing management practices. The evaluation shows a good understanding of the area management section, which contributes to the development of superior human resources for fauna management at LPHD Tuwung. Data from the protection and security section of the Tuwung LPHD area, regarding the role of the area management section, can continue to be improved through training approaches to management and maintenance of fauna, as well as community awareness and development. Management of fauna in village forest areas needs to be carried out wisely and sustainably. Training on management and maintenance of fauna in the LPHD environment for village communities is very necessary as an effort to increase competence in maintaining the sustainability of forest ecosystems, including efforts to increase community awareness about the need to preserve fauna in village forests. The policy implications of this activity emphasize the importance of developing policies that support training and education of village communities in the management and maintenance of fauna. Such policies should include the provision of adequate resources and technical support to ensure the implementation of sustainable and effective forest management practices, as well as understanding the regulatory framework that strengthens the protection of village forest fauna and ecosystems through active community participation.

Abstract

The examination on variations of morphological characters among 35 specimens of Calloselasma rhodostoma (Kuhl, 1824) from four different populations in Indonesia has been completed in this study. Univariate and multivariate analyzes allowed us to recognize the clustering of four populations through morphological diagnosis. The results of the average body size (Total Length) showed that the largest male is from Kangean Island (579.33 mm), while the largest female is from Java (841.07 mm). Comparison of meristic analysis represented three clusters from Principal Component Analysis (PCA) which is considered to be independent population. Here we also described three types of cephalic scalation variation that called small accessories scales and their distribution in Indonesia.  Keywords: C. rhodostoma, Indonesia, Meristic, Morphometry, Viperidae.
