Abstract. Hendrayana Y, Sudiana E, Adhya I, Ismail AY. 2022. Bird diversity in three Ficus species in the Kuningan Lowland Forest, West Java, Indonesia. Biodiversitas 23: 2255-2261. Frugivorous birds are an important group in tropical forests, as they promote a wide diversity of plant species and animal communities via tree seed dispersal. The presence of these avifauna depends on food, such as fruits provided by Ficus spp. This study examined the diversity of birds in three species of fruiting Ficus trees located in a secondary, natural lowland forest in Mount Tilu, Kuningan, West Java, Indonesia. Bird numbers in Ficus benjamina L., Ficus sinuata Thunb., and Ficus kurzii King were determined using the concentration count method. The data were analyzed using the Shannon–Wiener diversity index (H?), evenness index (E), and dominance index (Simpson’s D). The results showed diversity index values of H´ = 2.255, E = 0.353, and D = 0.8342 for F. benjamina; H? = 2.305, E = 0.5014, and D = 0.8376 for F. sinuata; and H? = 2.305, E = 0.5014, and D = 0.8694 for F. kurzii. The bird species with the highest number of individuals was Pycnonotus simplex Lesson, 1839 (378 individuals, 20.8%), followed by Megalaima australis (Horsfield, 1821) (320, 17.7%), Pericrocotus flammeus (J.R.Forster, 1781) (203, 11.2%), Dicaeum trigonostigma (Scopoli, 1786) (116, 6.4%) and Pycnonotus melanicterus (Gmelin, 1789) (109, 6,01%). By (Horsfield, 1821) knowing the important role of ficus trees as a source of food for various species of birds, this information becomes important and can be used by forest managers to support biodiversity conservation, especially bird conservation.

Abstract. Herlina N, Widhiono I, Proklamaningsih E, Sudiana E, Nasihin I, Nurdin. 2025. Forest edge effects on medicinal plants diversity in lowland forest in Gunung Tilu, West Java, Indonesia. Biodiversitas 26: 2873-2881. Forest edge effect is an ecological phenomenon that affects diversity of medicinal plants in the border area between forest edge and the interior. Gunung Tilu in West Java, Indonesia, is a lowland forest area with abundant natural resource potential, but the surrounding communities often use various resources in the form of wood and non-wood forest products, specifically medicinal plants which might cause edge effect. This study aims to analyze the diversity of medicinal plants and determine the effect of forest edges on the diversity of medicinal plants on the northern slopes and western slopes in the Gunung Tilu forest area. Line transect method was used to collect medicinal plant data. Sampling was done by making plots to analyze the composition, dominant species, diversity index, evenness index, and community similarity index. Furthermore, environmental variables such as temperature, humidity, sunlight intensity and soil pH were analyzed using the Spearman correlation test. The results showed that there were 89 species of medicinal plants classified into 41 families. The families with the largest number of medicinal plants came from the Asteraceae and Moraceae families. On the western slope, the understory, seedling, pole, and tree levels did not experience significant composition at various distance, but at the sapling level, changes occurred at a distance of 260 meters. On the northern slope, there were different variations in edge depth at each growth level where in understory, seedlings, and saplings, the edge depth reached up to 260 meters, while at the pole level, changes occurred at a distance of 240 meters and trees at 120 meters. This shows that tree communities adapt more quickly to environmental condition in the forest compared to other stages.
