Scarification is widely conducted in northern Japan to remove understory dwarf bamboo species in degraded forests for replacement with tree species. To explore ways to enhance species diversity and restoration of mixed forest at the treated site, we clarified the mechanisms that lead to compositional heterogeneity of plant species. We evaluated the relative importance of environmental factors (scarification properties, soil properties, light conditions, litter cover, and presence of canopy trees) for the demography of tall tree species (emergence, mortality, and growth) and whole vegetation structure (species diversity and composition) over the two growing seasons immediately following scarification. Of tall tree species, Betula spp. were dominant (60% in total density), followed by Abies sachalinensis (Fr. Schm.) Masters, Acer mono Maxim., and Phellodendron amurense Rupr. Light intensity was an important factor, having mostly negative effects on the demography of these species. Soil factors (e.g., nitrogen content, moisture) affected the demography mainly of shade-intolerant or hygrophilous species. In general, extreme environmental conditions led to the dominance of grasses, forbs, and lianas rather than tall trees. Maintenance of canopy cover, which limits light and supplies seeds as well as litter, proved to be most important in promoting plant species diversification on the scarification site.

A study was carried out to find the butterfly species diversity and abundance in Putalibazar Municipality, Syangja, Gandaki, Nepal, from June 2019 to July 2020. Pollard walk method was used for data collection in three different habitat types: forest, agricultural land, and settlement area. The study was performed in all seasons: pre-monsoon, monsoon, post monsoon and winter. A total of 180 butterfly species from 108 genera and six families were recorded. The overall Shannon-Wiener diversity index (H) was 4.48. The highest diversity was represented by the Nymphalidae with 67 species (H= 3.79). Butterfly diversity and species abundance was highest in the forest area (147 species, 1199 individuals; H= 4.47). The highest species richness (109 species) was observed in the monsoon season.

Research on Diversity and distribution of butterflies, was held at the Campus Indralaya Sriwijaya University of South Sumatra. The purpose of this study was to obtain information species diversity of butterflies at the Sriwijaya University of Inderalaya and distribution of species of butterflies in several different habitat types in the campus area Unsri Indralaya. The study used purposive and collection methods in November 2014-january 2015. Sampling sites were divided into five locations: Arboretum, Science Faculty, Faculty of Law, Faculty of Agriculture and Swamp Cape Disconnect. The parameters used are the index of species diversity, dominance index, and evenness index. The results showed that the diversity of butterflies in the region is classified as moderate. Overall found as many as 40 species of butterflies with a number of 609 individuals consisting of 5 the Papilionidae, Nymphalidae, Pieridae, Lycaenidae, and Hesperiidae. Regions Sriwijaya University has a diversity of butterflies that were moderate with criteria (H'1≤H'≤3), in each different habitat types, and not found butterfly species that dominate in every type of habitat in this Unsri region. Distribution of butterflies found in the campus area Unsri Indralaya categorized fairly evenly with a range of values from 0.58 to 0.68.Keywords: Butterflies,  Diversity,  Distribution , Sriwijaya University of Indralaya

The present study was carried out to reveal the butterfly species diversity in the Jabalpur City, Madhya Pradesh, India.  Study was carried out from January 2008 to 2018. A total of 112 species were recorded, with an addition of 41 new species for Jabalpur district and one species for the state of Madhya Pradesh.  Of the total, 42 species were very common, five were frequent common, 18 were rare, and four were very rare. Nymphalidae was dominant with 39 species, followed by Lycaenidae with 38, Pieridae with 15 species, Hesperiidae with 14, Papilionidae with eight and Riodinidae with one species.  About six species of the recorded ones come under the protection category of the Indian Wildlife (Protection) Act, 1972.  The study illustrated the value of Jabalpur City area in hosting valuable resources for butterflies.

Abundance And Diversity

Frugivorous butterflies were studied in a set of forested islands (0.1 to 1.15 ha) in a reservoir in eastern Venezuela to investigate the effects of fragmentation and the resulting isolation on their abundance, diversity and species composition. While some islands showed reduced abundance and species diversity in comparison to unfragmented (or control) sites, others did not. Isolation status affected both butterfly abundance and diversity. Islands located close to their colonizing sources (0.1–1 km) tended to support similar densities of butterflies but lower numbers of species in comparison to control sites. Far fragments (1–3 km from their colonizing sources) tended to harbour lower butterfly densities in comparison to control sites but undiminished numbers of species. Species composition varied significantly between control sites and islands and amongst control sites, near islands and far islands. Interspecific differences were observed in species' responses to fragmentation. Charaxines, medium-sized satyrines, morphines and brassolines may be vulnerable to extinction after habitat fragmentation while small-sized satyrines may be relatively resistant. Observations during the dry season indicate that butterfly species may exist as mainland-island metapopulations in Lago Guri, in which small habitat fragments require recolonization every year from source populations in large islands and mainland habitat.

Observation Method

Butterflies are one type of insect found in the green open space of Pontianak City. Butterflies can be used as bioindicators of environmental changes because butterflies are very sensitive to biotic and abiotic factors (Rizal, 2007). This study aims to obtain data and analyze the diversity of butterfly species in the green open space of Pontianak City. The study used a field observation method with sweeping net techniques and explored areas in three habitats namely Sylva Untan Arboretum, Untan S1 Forestry Campus and West Kalimantan Governor's Hall Pavilion. The three green open spaces were chosen based on the density and diversity of the vegetation. The results of the study found 22 types of butterflies. The same six types are found in three different types of open green space, namely Leptosia nina, Agamemnon Graphium, Papilio polytes, Hipolimnas bolina, Eurema hecabe, and Appias lybithea. The species diversity index at the Arboretum has a value of 2.74, Campus S1 Forestry Untan with a value of 2.19 and Pendopo Park with a value of 2.02. This value indicates that species diversity in green open space is classified as medium.Keywords: butterfly diversity, green open space, bioindicator
