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.

Abstract

The Minnow Trap is a simple sampling gear, efficient, easy to operate, affordable, easy to make, and has been used in research in the fisheries and aquatic ecology for more than 90 years. The brightness, color, and visual obstruction of fishing gear or fish traps affect the behavioral response of target fish, considering that each fish has a specific level of color sensitivity. The color effectiveness test of fishing gear is an important prerequisite for the use of sampling tools, and it needs to be evaluated to understand the gear performance and avoid potential sampling bias. The purpose of this study was to test the color effect of the minnow trap on diurnal fish in the Gajah Mungkur Reservoir waters. The research was carried out in Gajah Mungkur Reservoir, Wonogiri Regency, at two stations. The sampling conducted at 09.00 - 11.00 and 13.00 - 15.00 Indonesian West Time, where the initial survey is estimated to be the highest time for diurnal fish activity. The minnow trap used in this study is four colors vinyl-painted double funnel cylindrical minnow trap with a 5x5 millimeter mesh size and a conventional umbrella minnow trap used as control. The sampling results are then recorded on the datasheet and analyzed using Microsoft Excel. CPUE (Catch Per Effort Unit) of each unit is then calculated and statistically analyzed by Kruskal-Wallis test and Kolmogorov-Smirnov normality test through SPSS 25.0 software. The test result of five unit minnow traps from 40 installations and two hours of deployment time, 80 individuals were captured, consisted of seven species of freshwater fish. CPUE values ranking consecutively from the highest from silver units (1.375), black (1.25), green (1.125), red (0.9375), and control (0.3125). The Kruskal-Wallis analysis showed that all tested units do not have a significant difference. Keywords: Color, catch per unit effort, fish, minnow trap.

Abstract

The diversity of Butterfly in Coban Rais is one of the potential resources for tourism product diversification and development. The aims of this paper are to determine the magnitude of the butterfly potential as a form of tourism products diversification and development in a sustainable tourism industry. There are 107 species of butterfly that come from six families was found in Coban Rais waterfall. Some species have a very large population in a specified activity, such as mud-puddling and mating. Udara akasa has the highest potential to make colony and Cyrestis lutea is a species that have the potential as a major attraction in the mud-puddling activity. Sector 3, the location of riparian with sand and gravel, is the site of the largest butterfly visits. The dry season is the highlight of a butterfly visit in Coban Rais. Development of human resources is important for the tourism products diversification in Coban Rais, i.e. the butterflies observer and visitors services. We recommend establishing a breeding center for butterfly population recovery and educational goals for visitors.Keywords: butterflies, Coban Rais, product diversification.

Abstract

The remaining tropical forest on the south coast of the Malang region is one of the secluded areas that served as an important habitat for its biodiversity, particularly for avians. Nevertheless, the presence of the road structure that crosses over the forest might impact avian communities, which needs to be investigated. The avian survey was conducted to investigate the diversity, community profiles, abundance, and feeding guild based on two different ecosystem patches (on the roads versus outside the road structures) during January–April 2022. The audiovisual encounter methods were performed during the surveys on a total of ten sampling points. Avian species were identified using field guides where the conservation status was based on the national regulation (P106 KLHK), CITES, and IUCN Redlist. The comparison through the avian community based on species richness was analyzed using Venn Diagrams and predicted using rarefaction and interpolation curves on INEXT packages. Additionally, the comparison of sizes of avian abundance was investigated using the α-diversity parameter index, and the feeding guild was determined by five diet guilds. In total, 2536 individuals from 67 species, 34 families, and 13 orders were found during the survey. The avian communities were richer outside the road structure, but their abundance qualitatively reveals that both different ecosystem patches showed relatively good condition. Overall, road structures generate both positive (unique habitat patches) and negative (physical barriers that could disrupt natural ecological processes) impacts on avian diversity. In light of these, sustainable management and conservation action plans were urgently needed to prevent the negative effects on avian communities posed by the road structure.

Abstract

Land cover heterogeneity can affect the structure of biodiversity in the supplied niche, so it is necessary to know the taxa community. This study aimed to understand the effect of land cover variation on the diversity and community structure of soil arthropods. The types of habitats used include urban areas, agroforestry, gardens, and natural forests which are determined in the Malang Region, East Java, Indonesia. Hand sorting and hay bait traps were applied in this study to obtain a variety of arthropod soils and the Berlese-Tullgren funnel was used to extract them. As a result, there are 25 families from 15 orders collected based on their ecological roles. The abundance of Philoscidae in sites S1 and S2 (urban green space), Talitridae in site S6 (agroforestry), and Isotomidae in sites S3, S4, and S5 (highland mixed forest) was highest and dominant. Site S7 has the highest diversity (H' = 2.56; 1-D = 0.90; J' = 0.76) even though its family richness is lower. The site S3 counter-site had relatively high taxa richness (TR = 13), but low diversity (H' = 1.02; 1-D = 0.39; J' = 0.16). Based on clustering analysis and NMDS ordination, 3 classifications of habitat types were obtained, namely I (S6 & S7), II (S3, S4 & S5), and III (S1 & S2). Mixed forest habitats contain a more complex diversity of soil arthropods, which can serve as a model for improving the fertility of disturbed ecosystems.

Abstract

The distribution of the Reinwardt's Gliding Frog, Rhacophorus reinwardtii (Schlegel, 1840), was recently thought to be restricted in Java. Furthermore, the constant and rapid deforestation in Java highlight the significance of the frog's habitat requirements in establishing the accurate species' conservation status. This study aims to predict the suitable habitat for this species in Java and to identify the habitat characteristics in Malang Region-East Java. Using the Maximum Entropy (MaxEnt) approach, we modelled the distribution of species and examined numerous types of breeding sites in Malang Region. Our findings revealed that the species inhabits a much more restricted and fragmented habitat in Java, where it inhabits both forest and agroforestry areas.

Abstract

We found an active nest of endangered Brown-cheeked Bulbul (Alophoixus bres) with two chicks in nest-adoption program at Jatimulyo village, Yogyakarta province, Indonesia on 19 December 2021. It was placed on the lateral branch of apus bamboo (Gigantochloa apus) 1.5 m high. The nest was cup-shaped, with outer diameter of ± 8 cm, inner diameter of ± 6 cm, and depth of ± 3 cm. It was made of living non-vascular plants and plant fragments. Our observation revealed that the food of the chicks was primarily comprised of insects (in the morning) and fruits (at midday). The insect preys include caterpillars, Lepidoptera, Coleoptera, Orthoptera and Diptera. The fruits were mangir, lempeni, and senggani.

Abstract

Marine plastic debris that enters the sea can be fragmented by physical and chemical factors, then float in the water column or accumulate in sediments, which have the potential to be ingested by marine biota, causing digestive system disorders, fecundity, eating capacity, reproduction, and death. This study aimed to identify the accumulation of microplastics in water and sediments in Outer Ambon Bay using a purposive sampling method and descriptive analysis for data related to microplastics' type, color, and size, as well as follow-up tests of the least significant difference. The results show that the waters of Outer Ambon Bay have been polluted by microplastics. The number of microplastic particles found in water samples at three different depths (0, 50, and 100 cm) was 201 particles L-1, and in sediment samples, it was 325 particles g-1. It is supported by the fact that the type of fiber has a thin shape and size and can float on the surface of the water and by the existence of beaches where there are fishing activities, boat ports, rivers, and densely populated areas, as well as sandy and muddy sediments that can trap more microplastics during the tidal period. Therefore, it is necessary to prevent the waste problem in the waters of Ambon Bay. Keywords: Identification, Marine Pollution, Microplastics, Outer Ambon Bay.

Abstract

Barramundi fish is one of the most important aquaculture commodities, with cultivation challenges closely related to its survival and growth. There is still a lack of information on digestive enzymatic activity profiles and larval growth, and the use of Australian brooders rather than Indonesian brooders is still frequent. This study aims to investigate digestive enzymatic activity profiles and their correlation to the growth performance of barramundi larvae, Lates calcarifer (Bloch, 1790), originating from Indonesia and Australia. The digestive enzyme activity profile was evaluated using real-time quantitative polymerase chain reaction (RT-qPCR). First, larvae were reared in captivity till day 20 (20 dah). During this rearing, measurements of length and weight growth were done every day. Experiment data shows Australian fish larvae were greater than that of the Indonesian. Their digestive enzyme activity also confirmed that Australian larvae had more activity than Indonesian larvae.
