Xanthostemon novoguineenis (vernacular name: Sowang), an endemic plant in Papua from Myrtaceae family, is found widely near the buffer zone area and Mt. Cyclops Nature Reserve (MCNR) area. This research aimed to record the association of animals towards X. novoguineensis on its natural habitat. The survey was conducted in Cyclops buffer zone near Sentani City, Papua Province, Indonesia. The result showed that an interaction of animals directly to X. novoguineensis was documented and identified. Some insects species have an association with X. novoguineensis, namely black wasp (Isodontia sp 1), black-orange wasp (Isodontia sp 2), red weaver ant (Oecophylla sp 1) and black weaver ant (Oecophylla sp 2) have an association directly to flowers of X. novoguineensis. Furthermore, stick insect (Scepthrophasma sp) and spider (possibly from Araneae family) have an association with the leaves and trunks of this plant. Based on the finding, some leaves of these plant are fed by insects. It is indicated by a pattern of insect bites on the leaves.  Key words: buffer zone area,  cyclops, insect, sowang, Papua

AbstractKnautia sarajevensisis an endemic plant of the Dinaric Alps and is mainly distributed on Bosnian Mountains. Due to the quite large flower heads and easy maintenance, this plant has a potential use as a substitute ornamental plant forK. arvensisin perennial beds. The current study evaluated the germination process in different treatments in an attempt to suppress dormancy and increase germination rate, and to develop a successful protocol for micropropagation. An over 60% germination rate was achieved through cultivation of seeds on MS basal medium with reduced mineral nutrient composition and the absence of sucrose. On the other hand, a below 10% germination rate was achieved with untreated seeds. Suppression of apical dominance was achieved through application of high concentrations of kinetin, apical shoot decapitation or cultivation of shoots in liquid media. Overall, liquid cultures were more successful as a micropropagation system for this plant. Shoots spontaneously developed roots on multiplication treatments and were successfully acclimatized. Moreover, phenolic compound profile was analysed in the light of the possible medicinal potential of this plant. Variable amounts of total phenolic compounds as well as individual phenolics were recorded, according to treatment and solidification of media. An increase in rosmarinic acid content was reported for kinetin treatments and acclimatized plants comparing to mother plants in natural habitat. The present study shows that choice of cytokinin concentration, explant type as well as culture type influences not only shoot proliferation and apical dominance suppression but alsoin vitroproduction of phenolics.

Rafflesia patma is an endemic plant of Pangandaran, West Java which is protected because of its rare status. The purpose of this research is to study the population structure, distribution patterns, and the effect of the physical environment of abundance R. patma in Pananjung Pangandaran Nature Reserve, West Java. The method used in this research was a survey method with a purposive sampling technique. Sampling was conducted using quadrat plots. The population pattern distribution was defined by a standardized Morisita index, and the analysis of abiotic environmental factors was determined by Principal Component Analysis (PCA) using PAST3. The results showed that there were 114 R. patma individuals scattered in several research areas in Pananjung Pangandaran Nature Reserve, they were Gua Parat (3 individuals), Cilegon (13 individuals), Pasir Putih (12 individuals), Badeto (48 individuals), and Curug Leutik (38 individuals). The distribution pattern of R. patma in Pananjung Pangandaran Nature Reserve was clustered with the Morisita index value (Id) > 1. Based on the PCA analysis, results that support the classification of the cluster analysis were obtained. Based on four abiotic environmental conditions analyzed, the most dominant character in influencing the distribution patterns and population structure of R. patma is light intensity.

Territorial distribution of four alleles of one histone H1 subtype was investigated in the natural population of a leguminous plant Vicia unijuga A.Br, inhabiting an area of about 35 km2, including Novosibirsk Academy Town (Akademgorodok). Histone H1 was isolated from pools of 100 plants (one leaflet per plant) collected from points of approximately 100 m2. The proportion of alleles estimated for 119 different points revealed a radial cline. The frequency of an allele that predominates everywhere in the circumference decreases towards the historical centre of Akademgorodok, while two other alleles show the opposite tendency. The observed pattern of territorial distribution was likely due to some man-caused factor (presumably insecticide treatment) that has been acting for a period of time not exceeding the 25 years of Akademgorodok's existence. Key words: histone H1 polymorphism, Vicia unijuga A.Br., natural selection in an urbanized area.

Praying mantids are charismatic insects that are considered beneficial to humans because of their insectivorous lifestyle and because of their aesthetic appeal. Despite this, many praying mantid species remain understudied. One species that occurs in the southeastern United States is the grass-like mantid, Thesprotia graminis (Scudder) (Figure 1). This small, cryptic mantid species is light brown to green in color and can easily blend in with pine needles and grass, making it difficult to detect in its natural habitat. Although this mantid may be mistaken for a stick insect (Order: Phasmatodea), especially when its forelegs are held directly in front of the body and it resembles a blade of grass, the raptorial forelimbs reveal the insect’s true identity. There are 14 Neotropical species within the genus Thesprotia, all of which occur in South America except Thesprotia graminis (Rondon et al. 2007). The type specimen for this species is a male that was collected in Gainesville, Florida. It is vouchered in the entomology collection of the Academy of Natural Sciences in Philadelphia, Pennsylvania.

Tovtry is a complex of Miocene fossils reef buildups that rise in a scenic ridge and hills above the surrounding plains of Podillya region. The Tovtry zone consists of main ridge (the late Baden barrier reef), isolated Tovtry hills (the late Baden bioherms, located east of the ridge), isolated tovtry (the early Sarmat bioherms, located west of the main ridge), the territories of the former channels, lagoons and passes between hills, where the modern rivers flows. The correlation and form of relief of Tovtry zone elements are the basis of detailed geomorphologic zoning. Within geomorphological area of Podillian Tovtry distinguish three subdistricts – Zbarazh, Medobory and Kamenec-Podolsky regions. The Zbarazhky Tovtry is stretching from Pidkamin village (Lviv region) to the valley of Gnizna river and includes Mylnivskyy, Zbarazhsky and Lub’yanetskyy hills of Tovtry. Within Podillian Tovtry are 85 objects of nature reserve fund (NRF), dominated by the number of botanical (20) and geological (19) natural monuments. The largest area is occupied by National Nature Park “Podilski Tovtry” (261 316,0 ha) and nature reserve “Medobory” (9 516,7 ha) and 7 landscape reserves (2 423,2 ha). The structure of NRF of Zbarazhsky Tovtry dominated by the number of botanical (6) and geological (6) natural monuments, and the largest area is occupied by 2 zoological reserves (6 041,0 ha). The particularly valuable geologic-geomorphologic objects of Tovtry have been identified (the Tovtry main ridge areas and isolated tovtry hills, the outcrops of reef sediments, rocks, canyon sections of the river valley, waterfalls etc.), they are protected in the form of geological nature monuments “Kydanetski rocks”, “Podillian Tovtry outliers”, “Sarmat sea outliers”, “Big Saddle” and into botanic reserve “Acute grave”. Share of environmental protection objects aimed at the protection of geological and geomorphological Tovtry formations in the Zbarazhsky Tovtry NRF is less than 2 %. The creations of the regional landscape park (RLP) “Zbarazhsky Tovtry” in the territory f the main ridge and surrounding areas with isolated tovtry hills from Left Seret river valley to Stryyovetski stream valley has been proposed. The park administration should be placed in the Zbarazh, where in 1994 the historical and architectural reserve “Zbrazh” has been created. Into RLP reserve zone should be included the most outstanding areas of main ridge (natural landmark Pozharnytsya, mount Hontova, mount Zubova) and isolated tovtry hills (Lub’yanetski Tovtry). The RLP will include “MilneBlihivskyy” (3 488,0 ha) and “Maloberezovytsko-Ivanchanskyy” (2 553,0 ha) zoological reserves, 4 botanical reserves, 5 geological and 2 hydrological reserves, 4 botanical nature monuments. Two circular routes from Zbarazh for the tourism development into regional landscape park “Zbarazhsky Tovtry” have been developed. The first route includes unique historical and architectural monuments and objects of inanimate nature, and the second – botanical and zoological objects and nature monuments. The landscape reserves “Tovtry steppe” and “Stryyovetski Mountains”, geological nature monuments “Fold bordering in the reef limestones in Bilokrynytsya village”, “Kolodiyivski giants”, “Hontva Mountain” and natural landmark “Zaluzhanskyy forest” are proposed to create in Zbarazhsky Tovtry. The chain of nature reserve objects will preserve the unique geological and geomorphological formation of Zbarazhsky Tovtry region. Key words: Zbarazhsky Tovtry, main ridge, isolated tovtry hills, natural reserve fund, outstanding geology-geomorphologic objects, geotourism.

Mount Sigogor Nature Reserve area is a mountainous tropical rain forest, administratively located in Pupus Village, Ngebel District, Ponorogo Regency, East Java, Indonesia. One of the main functions of this nature reserve is as a water catchment area for the villages around the nature reserve area. Water sources and flows within the Mount Sigogor Nature Reserve area have the potential as natural habitat for dragonflies. This study aims to determine the diversity and abundance of dragonflies (Odonata) in the Mount Sigogor Nature Reserve Area. The method of collecting dragonflies data used the Visual Day Flying method by recording the diversity of dragonflies species and counting the number of individuals from each observed dragonflies species. The data obtained were analyzed using the Relative abundance, Shannon-Wiener Heterogeneity Index and the frequency of Presence. The results of the research conducted showed that there were 14 species from 7 families with a total of 464 individuals. The Shannor-Wiener diversity index shows that the diversity value is H'= 1.81. Meanwhile, the presence frequency analysis showed that there were four species with a value of 100% which were classified as abundant Frequency of Presence, namely Euphaea variegata, Vestalis luctuosa, Rhinocypha anisoptera and Coeliccia membranipes.

Abstract. Darsono, Riwidiharso E, Santoso S, Sudiana E, Yani E, Nasution EK, Aprilliana H, Chasanah T. 2020. Insect diversity in various distances to forest edge in small nature reserve: A case study of Bantarbolang Nature Reserve, Central Java, Indonesia. Biodiversitas 21: 4821-4828. A nature reserve is a conservation area with the objective of conserving the biodiversity of the flora and fauna within its boundaries. However, many nature reserves are fragmented into small extent and isolated from natural habitat, causing the so-called edge effect. This research aimed to investigate insect diversity across various distances to forest edge in small and isolated protected areas. Research was conducted in the Bantarbolang Nature Reserve, Pemalang District, Central Java, Indonesia. A survey was conducted to determine the diversity of insects, especially those from the Diptera (flies), Lepidoptera (butterfly), and Hymenoptera (bees and wasp) orders. The environmental parameters recorded were temperature, humidity, and flowering plant diversity and abundance. Line transects were laid at a length of 100 m, parallel to the forest edge at three different distance ranges from the edge: 0-50 m, 50-100 m, and 100-150 m. Species diversity was measured using the Shannon-Wiener index, evenness index, and Sorensen similarity index. Over the 4-month study period, 1713 individual insects from 63 species and from the following three orders were found: Lepidoptera (Rhopalocera; 33 species, 5 families, 932 individuals); Hymenoptera (20 species, 423 individuals) and Diptera (10 species, 7 families, 376 individuals). The highest diversity was found at the edge of the forest and the lowest at the distance of 100-150 m from the forest edge. While the study area can support a diversity of insects, especially pollinating insects, but it is unable to support the conservation of light-sensitive butterflies. The results of this study suggest that small nature reserve can support a diversity of pollinating insects, especially from the Diptera, Lepidoptera, and Hymenoptera. However, it has limited conservation potential because of the significant impact of forest edges on species composition, especially on specialist butterfly species with habitat in forest interior.
