Abstract

Meru Betiri National Park (MBNP) is a conservation area located in East Java that has a diversity of flora and fauna. However, the information about entirety diversity in this area is still uncleared, due to limited scientific research, one of which is amphibians. So, the aim of this study is to explore the diversity of amphibian species (order Anura) in Bandealit Resort, MBNP. Data collection was carried out on January 6-8, 2023 in four representative habitat types i.e., terrestrial, arboreal, semi-aquatic, and aquatic. The data collection method was using Visual Encounter Surveys (VES) on each observation line with a length of 300m. The ecological data collected included the species names of amphibians (Anura) and the number of individuals of each species. Furthermore, data analysis was using species composition and species diversity using the Shannon-Wiener index (H'). Based on the results, six species of Anura were found (Fejervarya cancrivora, F. limnocharis, Leptobrachium hasseltii, Kaloula baleata, Hylarana chalconota, and Polypedates leucomystax) belonging to five families (Dicroglossidae, Megophryidae, Microhylidae, Ranidae and Rhacophoridae). Species P. leucomystax was found with the highest number of individuals (eight individuals) and occupied arboreal, terrestrial, and semi-aquatic habitat types. Based on the Shannon-Wiener index, the species diversity value of the order Anura amphibians was obtained in the moderate category (H'=1.47). This shows that the Bandealit Resort in MBNP provides an important habitat for several species of the order Anura amphibians. Furthermore, the results of this study also provide updated data regarding the existence of amphibian species of the order Anura in MBNP, especially Bandealit Resort.

Abstract

The Long-Tailed Macaque (LTM) (Macaca fascicularis Raffles, 1821) is a member of the Cercopithecidae which is included in the Vulnerable status. Information on the habitat characteristics of these species is needed to support in-situ conservation efforts. This study aims to determine the habitat characteristics of LTM in Kucur Resort at Alas Purwo National Park (APNP) based on the forest strata occupied by the LTM, Normalizes Difference Vegetation Index (NDVI), and river distance. The research procedure begins with a preliminary survey to determine the six lines of observation. The data used are primary data (LTM encounter points, forest strata they occupy, and data on tree species where they meet) and secondary data (NDVI variables and river distance). Both data were analyzed using a Geographic Information System (GIS) approach. The results showed that the LTM at Resort Kucur TNAP was found in four different groups. The results of data analysis show that the habitat characteristics of the LTM in Kucur Resort based on the forest strata it occupies are at a tree height level of 0-30 meters (strata E-B) which has branches, canopies, and produces young leaves and fruits. Furthermore, the LTM habitat has vegetation characteristics with medium density and cover which has an NDVI value of 0.3-0.5. This indicates the character of this habitat is used as a place to rest, socialize, and avoid from predators. Based on the distance of the river, the habitat characteristics are the location which is quite far from the river, which is > 300 meters. Based on the data on the habitat characteristics of LTM, it shows that Kucur Resort provides a fairly good habitat for the LTM.

Abstract

Grasshoppers (Caelifera) are herbivorous insects that act as first consumers in the food chain. Grasshoppers can detect the presence or absence of plants as a source of food and a place to live, as well as being an indicator of environmental recovery. This study aims to determine the diversity of grasshopper species in the rehabilitation zone of Bonangan Block, Resort Wonoasri Meru Betiri National Park. The sampling method used a structured roaming technique. The results obtained nine types of grasshoppers covering seven genera with a total of 228 individuals. The diversity index value obtained is 1.86. The conclusion of this study was that the composition of grasshoppers included nine types of grasshoppers found, namely Oxya sp., Catantops sp., Trilophidia sp. (1), Trilophidia sp. (2), Schistocerca sp., Acrida sp., Phlaeoba sp., Atractomorpha sp. (1) and Atractomorpha sp. (2). The value of the diversity index of grasshoppers is in the medium category with the diversity index value of 1.86.
