Pollination is an important ecosystem service in the maintenance of biodiversity and most importantly in food production. Pollination is on the decline due to habitat loss, exotic species invasions, pollution, overharvesting, and land use changes. This study analyzed the abundance and diversity of flower visitors’ of Ocimum kilimandscharicum in Kakamega forest with increasing distance from the forest edge. Data were collected through direct observation and sweep netting. Six study sites were identified along two transects each 2.5 km long and labeled A to F. Distance in metres from the forest edge to each site was A=221, B=72, C=83, D=198, E=113, and F=50. Sampling was done from 7:30 am to 4:00 pm, three days in a week for five months consecutively. Diversity indices of different flower visitors were calculated using the Shannon-Wiener diversity index. One-way analysis of variance was used to compare differences between sites and a two-sample t-test was used to identify mean significant differences in species diversity between the closest and the furthest sites. A total of 645 individuals belonging to 35 species were captured from 4 families. The highest diversity was at site F (H’= 2.38) which was closest to the forest edge and the lowest diversity was from site A (H’=1.44) which was furthest from the forest edge. Distance from the forest edge significantly influenced species diversity (F(3, 20)=14.67, p=0.024). Distance from the forest edge also significantly influenced species abundance between the furthest sites A, D, and E and the nearest sites F, B, and C to the forest edge (t=4.177; p=0.0312) and species richness (t=3.2893; p=0.0187). This study clearly demonstrates that Ocimum kilimandscharicum flower visitors play essential roles in pollination and their higher number of visits translates into higher numbers of seeds set. Many of these pollinators are associated with the forest and hence the need to conserve the Kakamega forest as a source pool for pollinators.

Petungkriyono forest is a tropical rainforest with high biodiversity. The increasing tourism activities in Petungkriyono lead to land conversion. Dragonfly (order Odonata) is a good bioindicator for aquatic and terrestrial. This study aimed to compare the community structure of Odonata in natural forests and tourist sites. The method of collecting imago Odonata was done by direct searching, samples were captured using sweep netting. The results showed that the dragonflies found in all locations consisted of the same family, 2 families (Gomphidae and Libellulidae) from the suborder Anisoptera and 6 families (Calopterygidae, Chlorocyphidae, Coenagrionidae, Euphaidae Platycnemididae, and Platystictidae) from the suborder Zygoptera. The total species of dragonflies found in Sokokembang were 15 species with a total of 293 individuals, Tirta Muncar 13 species of 287 individuals, Karanggondang 17 species of 276 individuals, and Curug Lawe 14 species of 242 individuals. The highest relative abundance of individuals was in the natural forest of Sokokembang is Drepanosticta spatulifera (26.28%) and in Karanggondang Vestalis luctuosa (24.64%), while in the tourist forests of Tirta Muncar and Curug Lawe were Euphaea variegata (34.84% and 28.51 %). The structure of the Odonata community is based on the Shannon-Wiener diversity index in the natural forests of Sokokembang (2.18) and Karanggondang (2.21) at the tourist sites of Tirta Muncar (1.84) and Curug Lawe (2.11). The results showed that the structure of the Odonata community based on the level of the diversity index value, evenness index, and dominance index in natural forests and tourist sites in Petungkriyono forest was not significantly different.

<p>Plants that have a wide range of insect presence, decreased insect diversity and abundance were so few consequenced because the absence of one insect species can be replaced by the presence of another. The bad consequences that occur are the types of plants that have specific insect specificities because the absence of these insects will cause the failure of plant pollination and will directly cause a decrease in crop production. This study aimed to determine the diversity of insect species that come in the soybean-tithonia intercropping. The method was used direct observation in tithonia-soybean intercropping, took insects using a sweep net in the morning. The results showed that there were 15 types of insects identified, namely <em>Epilachna</em> sp.; <em>Coccinella</em> <em>sexmaculata</em>; <em>Coccinella</em> <em>transveralis</em>; <em>Verania lineata; Ropalidia fasciata; Priocnemis</em> sp.; <em>Naupactus leucoloma; Piezodorus guildinii</em>; <em>Bemicia</em> <em>tabaci; Agromyza phaseoli; Spodoptera</em> sp.; <em>Nezara viridula; Paederus fusipes; Hylaeus</em> sp.; and <em>Trigona</em> sp. The range of results of the calculation of the diversity index showed that the five treatments in intercropping plants had the same abundance. So it was needed to calculate the highest diversity index value or maximum H expressed in Ln S. The maximum H value in this study is 2.708, which is a measure of moderate species diversity (1&lt;H’&lt;3).</p>

Merapi volcano as one of national park is an ecotourism site which is very potential to visit. Information about species diversity for a national park is very important especially if its area fluctuated susceptibly. Two years after 2010 Merapi eruption, there are no research about species diversity and evenness of Anuran in that place. The research is carried out during June-November 2012 which is dry season. The objective of this research is to study the species diversity and evenness of Anuran in southern slope of Mount Merapi. The research is carried out in 6 locations; those are Kali Kuning, Telogo Muncar, Telogo Nirmolo, Petak Pitu, Bukit Turgo, and Bukit Plawangan. We used Visual Encounter Survey (VES) method combined with transect in Kali Kuning, Telogo Muncar, and Petak Pitu. VES method combined with time search in Telogo Nirmolo and Bukit Turgo. VES method combined with track exploration in Bukit Plawangan. Species diversity is analyzed with Shanon-Wiener diversity index. Species evenness is analyzed with Pielou evenness index. Total individuals each species is counted to know species abundance. Species diversity of anuran in southern slope of Mount Merapi is consisted of 12 species’ which is distributed in 6 locations. The highest diversity and evenness of anuran is at Bukit Turgo (H’=1.31; E=0.94). The lowest diversity and evenness of anuran is at Petak Pitu (H’=0.49; E=0.3). Species diversity of anuran in southern slope of Mount Merapi is low (Bukit Turgo and Kali Kuning) and very low (Bukit Plawangan, Telogo Muncar, Telogo Nirmolo, and Petak Pitu). Species evenness of anuran in southern slope of Mount Merapi is stable (Telogo Nirmolo and Bukit Turgo), still labil (Bukit Plawangan, Kali Kuning, and Telogo Muncar), and oppressed (Petak Pitu).

Phytoplankton community plays an important ecological role in the aquatic ecosystems as the primary producers and forms the fundament of the aquatic food chain for supporting the water community. Thus, the phytoplankton community structure is a good indicator of water quality due to its sensitiveness to environmental stresses. Two newly dug ponds in Institut Teknologi Sumatera may give an opportunity to study the early colonizing stages of various freshwater communities including phytoplankton. The study attempted to determine the composition and abundance of phytoplankton. Samples were collected from two ponds (A and C) in the reservoir water of Institut Teknologi Sumatera. The content of Phosphorus (P), Nitrogen (N), and Chlorophyll-a (algae biomass) were determined. Phytoplankton had higher diversity in Pond C than Pond A in the study period, in which a total of seven taxa were found, namely Bacillariophycea, Cyanophyceae, Chlorophyceae, Conjugatophyceae, Dinophyceae, Euglenophyceae, Gymnodiniaceae. The most species abundance of both ponds was Peridinium sp. and Trachelomonas sp. The Pond C had the highest mean value of the Shannon-Wiener diversity index. The Linear mixed-effect model showed that low turbidity will result in high phytoplankton diversity. The finding of this study suggests that higher phytoplankton diversity would achieve a natural carrying capacity, and thus would serves as an indicator of ecosystem health.

Indonesia has a high diversity of ant species, but much remains unreported. In agricultural habitats, ants can act as predators, decomposers, and bioindicators for agricultural ecosystems health. This research aimed to study the species diversity of Formicidae on tidal swamp rice fields in Indragiri Hilir District. Sampling was carried out in two periods of rice planting. Samples were conducted in 4 sub-districts of rice production centers, namely BatangTuaka, Keritang, Reteh, and Tembilahan Hulu, using four sampling techniques (i.e., insect net, malaise trap, yellow pan trap, and pitfall trap). Diversity index (H ), Species richness index (d), Species Evenness index (J), and Similarity Index (Is) were calculated. We found 5,754 individuals consisting of 5 subfamilies and 43 species of Formicidae at the four studied areas. Subfamily Myrmicinaehas the highest individual abundance, 2.578 individuals, followed by subfamily Formicinae1.823 individuals, subfamily Ponerinae 776 individuals, subfamily Dolichoderinae 575 individuals, and subfamily Pseudomyrmecinae 2 individuals. Diversity of plant species and environmental factors can affect the diversity index, species abundance, and abundance of individual Ants.
