Abstract. Hendrayana Y, Widodo P, Kusmana C, Widhiono I. 2019. Short Communication: Diversity and distribution of figs (Ficus spp.) across altitudes in Gunung Tilu, Kuningan, West Java, Indonesia. Biodiversitas 20: 1568-1574. The genus of Ficus is significant component in tropical rainforest ecosystem, consisting of large number of species and spreading across altitudes. This research was aimed to examine the diversity and distribution of species belong to Ficus genus in Gunung Tilu, Kuningan District, West Java as a basis for building conservation strategies. There were 12 species of Ficus found from the altitudes of 600 to 1000 m asl. The highest number of species was found at the altitudes of 600 - 700 m above sea level with 10 species, while the lowest number of species were found at the altitudes above 1000 m asl with only two species. The highest individual density was found at an altitude of 600 m asl, while the lowest density was at the altitude of 1000 m asl. The distribution pattern of Ficus spreads throughout the region of Gunung Tilu, Kuningan.

Abstract. Adhya I, Widodo P, Kusmana C, Sudiana E, Widhiono I, Supartono T. 2020. Short Communication: Population structure and habitat characteristics of Goniothalamus macrophyllus in Bukit Pembarisan forest, West Java, Indonesia. Biodiversitas 21: 1130-1135. Goniothalamus macrophyllus (Blume) Hook.f. & Thomson is a forest species with important medicinal value and widely used by many local communities. Excessive harvesting of this species has led to population decline and may lead to extinction. The aims of this research was to investigate population structure, habitat characteristics and environmental factors affecting local densities of G. macrophyllus in Bukit Pembarisan forest, Kuningan District, West Java, Indonesia. Purposive sampling was conducted at 17 locations during November 2017 to March 2018. The result showed that the population structure in the study area was dominated by seedlings (95% of the total number of individuals), followed by saplings (4%) and poles (0.1%). Seedlings, saplings, and poles were found growing across a wide elevational range (432-1,273 m asl.), at temperatures of 19-25°C, relative humidity of 80-90%, and soil pH of 4.61-6.46. The multiple regression analysis showed that soil nitrogen and soil pH affected seedling density, whereas soil clay content affected pole density. Our findings indicate that G. macrophyllus preferred acidic soils with high nitrogen and high clay content. We therefore recommend that future conservation efforts include the maintenance of existing poles, a prohibition on bark harvesting, and encouraging use of the leaves, rather than bark, for medicinal applications among consumers of G. macrophyllus.
