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.

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.

Agroforestry is a cultivation system that integrates crops like coffee with various vegetation, as applied in the Kalibaru District. The local community utilizes an agroforestry system by combining shade and undercover plants that can be utilized as food. The objective of this study was to collect a diversity of edible vegetation and investigate the local utilization. Data was collected by vegetation analysis and ethnobotanical studies related to their use. The result showed that 22 species of shade plants and 22 species of undercover plants were edible. The highest use value of shade species in coffee agroforestry are Leucaena leucocephala, Musa paradisiaca, Syzygium aromaticum, Carica papaya, and Artocarpus heterophyllus. Meanwhile, the highest use values in undercover species are Capsicum frutescens, Manihot esculenta, Colocasia esculenta, and Maranta arundinacea. The highest index of cultural significance for shade species is shown in Carica papaya, Leucaena leucocephala, Parkia speciosa, and Musa paradisiaca. Meanwhile, the highest index of cultural significance for undercover species is C. frutescens, L. esculentum, P. amarylifolius, and C. longa. This area can support local food resources and serve as a means of cultural preservation.
