The conversion of land functions can result in a decrease of environmental quality, which can reduce the diversity of butterflies. This study aimed to determine the diversity level and to find the most abundant and less abundant butterfly species around campus 4 UAD. The sampling was done at campus area, vacant land, rice fields and housing sites. Each of these sites had 2 plots and consisted of 5 subplots, respectively. Sampling was carried out four times, which was done in the morning at 08.00 - 11.00 and in the afternoon at 15.00 - 17.00. Butterflies caught using a sweep net. The data were analyzed by inferential analysis, namely Pearson correlation test. The calculation of the diversity level of butterflies was carried out by calculating the importance value index, the diversity Shannon-Wiener index, and the Simpson dominance index. The results showed that the diversity level of Shannon Wiener index of butterflies around the campus 4 UAD showed a low level (0.67). The species of butterflies found around campus 4 UAD were Acraea violae, Aphrissa statira, Appias libythea, Appias olferna, Catopsilia pyranthe, Catopsilia Scylla, Danaus Chrysippus, Elymnias hypermnestra, Junonia almana, and Junonia atlites. The most abundant butterfly was C. pyranthe with 125 individuals whereas the least abundant was A. libythea with 1 individual. This suggested that the ecosystem around campus 4 UAD is disturbed category; causing instability of the diversity that exists, including butterflies.

The detailed causal factors of flood have not been established, whether because of the damage of upper watershed, sedimentation resulting in shallow river, forest conversion, the decrease in abundance and structure or high rainfall. The study aimed at finding out the species diversity and structure of the limited production forest (LPF) from the seedling to the tree stage of Arui watershed in Manokwari district. The species diversity was determined based on Shannon-Wiener index, while vegetation structure was determined based on Importance Value Index. There were totally 92 plots of samples drawn using systematic sampling. The results of vegetation analysis showed that there were 174 species of 43 families with the species diversity of 1.5-1.8 that was categorized as moderate. The four dominant species that were always found in seedling, sapling, pole and tree stages included: Pometia pinnata, Teijsmanniodendron bogoriense, Chisocheton ceramicus, and Horsfieldia irya. The conversion of the LPF into non-forestry sector for the purpose of accelerating development must be reviewed by considering hydrology, land, biodiversity, and social and regional aspects in order to prevent and to reduce flood in the coming days.

Palasari Reservoir is the largest reservoir on the Bali island that serves as a water provider to meet the surrounding community's needs. The condition of the reservoir directly adjacent to the Palasari Forest makes the vegetation area around the reservoir play an essential role in maintaining groundwater reserves and reducing erosion in the reservoir area. This study aims to analyze the structure of vegetation and diversity and conservation efforts in the Palasari Reservoir green belt area. The method used is the density index, Shannon-Wiener index, the Simpson index, and the importance value index (INP) to determine plants' ecological position in a community. The results showed that the plants that had a role in the Palasari Reservoir green belt community included bananas, mahogany, and spathodea, which were demonstrated by the highest INP's ranging from 20.83%, 20.24%, and 19.80%. These three types of plants are adaptive and can reduce erosion. The value of plant diversity in the study area is moderate, with the dominance of species diversity at the tree level. Efforts to conserve green belts sustainably need to be done by increasing the number of endemic plants in reservoir areas such as pulai and bayur. Every element of society needs to watch out for it to maintain the regional identity.

Aim of study: We evaluate palm and tree species diversity in a floodplain forest and the changes affecting the plots subjected to different intensities of selective logging.Area of study: The western alluvial plains of Venezuela.Materials and Methods: A randomized complete blocks design was established 25 years ago with three felling treatments (trees with diameter greater than 20 cm, 40 cm and 60 cm). Each treatment had three replications, using 1 ha permanent plots. We have measured all trees and palms bigger than over 10 cm in diameter. The data set was used to calculate the Importance Value Index of each species, the Shannon-Wiener index, the Hill Numbers and the Chao-Sørensen index.Main results: Disturbance increases the importance value index of pioneer species like Cecropia peltata, Ochroma pyramidale and Triplaris americana. All treatments produce changes on the floristic diversity but most of them are not significant. Only the high impact treatment causes a decrease in the species richness, but after 5 year of recovery this parameter is close to its previous levels (N0= 43.5). In logged forests, species loss (9.2%) is lower than in the control plots (11.7%) and is also lower than the rate of occurrence of species input (14.6%).Research highlights: In these logged forests restoration of diversity is acceptable because is higher than 91% (Chao-Sørensen index). Selective logging, with low and medium intensity, is a disturbance that works in a similar way to natural disturbances. All the diversity indexes recovered the pre-harvest level values.Keywords: Caparo - Venezuela; ecological restoration; forest dynamics; forest management; forest succession; Intermediate Disturbance Hypothesis; permanent plots.

Butterflies (Papilionoidea) are Lepidoptera which have various ecological roles in maintaining the balance of the ecosystem and can be found in various types of habitats ranging from forest to urban areas. This research was conducted from March to June 2020 in four types of habitat, namely, rubber gardens, secondary forest, agroecosystem hatchery, and swamp forest using the Pollard transect method and the sweeping net technique for five days in each habitat type. The relationships between environmental factors and the number of species and individuals were analyzed with the Pearson correlation test. The number of individual butterflies obtained was 913 butterflies of 27 species from five families (Nymphalidae, Pieridae, Lycaenidae, Hesperidae, and Riodinidae). The highest diversity was found in rubber gardens (19 species) followed by secondary forest (17 species), swamp forest (12 species) and agroecosystem hatchery (10 species). The highest species diversity index was found in swamp forests, while the lowest was in the agroecosystem hatchery habitat. The types of butterflies found in all habitats are Eurema sari, Mycalesis horsfieldi and M. mineus. The most abundant butterfly family is Nymphalidae. The Pearson correlation test analysis results showed a relationship between environmental factors and the number of species and individuals found.Keywords: Diversity, butterflies, Papilionoidea, habitat ABSTRAKInventarisasi jenis kupu-kupu (Lepidoptera: Papilionoidea) di beberapa tipe habitat di Universitas Bangka Belitung Kupu-kupu (Papilionoidea) merupakan Lepidoptera yang memiliki berbagai peran ekologis dalam menjaga keseimbangan ekosistem serta dapat ditemukan di berbagai macam tipe habitat mulai dari kawasan hutan hingga perkotaan.
