This study aims to determine the diversity index and the comparison of insect diversity index in Gunung Leuser Bukit Lawang National Park in the Buffer ecosystem area. The research method uses a quantitative descriptive approach. The population in this study were all animals classified as insects (Insecta). The samples used were insects in the buffer forest area with 3 standpoints (lines). The data analysis technique uses the Shannon–Wiener diversity index. The results showed that the insect with the highest significance index (INP) from the three lines (without stands, rubber stands, and cocoa stands) was Macrotermes gilvus, namely 91.71 (rubber tree stands), 87.54 (cocoa tree stands), and 57. 42 (without stands). The insect diversity index H' using (Shannon-Wiener Index) from the three lines without stands (-2), rubber stands (-1), and brown stands (-1) were “low”. The low diversity index of the buffer forest is because the buffer forest in Bukit Lawang is a homogeneous forest.

Most of the tidal land in the lakeside of Rawa Pening is currently used for rice farming activities. This activity is thought to have negative impacts on seasonal herbaceous wetland ecosystem in this region. The study aimed to analyze the influence paddy fields toward the seasonal herbaceous wetland ecosystems in Rawa Pening Lake through an vegetation composition and structure approach. This study is a quantitative descriptive research with field observation method. Data of vegetation was collected using line intercept transect technique in the area widely of 625 m2 for each affected and unaffected ecosystem sample. Data analysis was performed by calculating the Sorensen Similarity Index (IS), the Margalef Diversity Index (R), the Shanon-Wiener Diversity Index (H'), the Dominance Index (C), and the Evenness Index (E). The results showed that there were differences in the composition and structure of vegetation on the two ecosystem samples, seen from the value of similarity index (IS) between both of them that included in the low criteria (39.85%). The results also showed that the Shanon-Wiener Diversity Index (H') and the Margalef Diversity Index (R) on the affected ecosystem sample  (H' = 1,9834; R = 1,825) are lower when compared to the unaffected ecosystem sample (H'= 2,1297; R = 2,112). So it can be concluded that the existence of paddy fields has changed the composition and structure of vegetation and reduced the diversity of vegetation in the affected ecosystem. Based on these conclusions, it is recommended to construct a sustainable management system of paddy fields on Rawa Pening Lake's tidal land as the effort for natural ecosystems maintenance in this region, especially in the biodiversity and ecological services preservation.

The basin of the Sinos River, located in the northeastern part of Rio Grande do Sul state, Brazil, has been highly impacted by industrial and urban activities. Water quality is low because of domestic and industrial sewage discharges. Most of the tributaries have suffered drastic structural interventions like canalisations and the removal of riparian vegetation. The aims of this study were to: 1) assess the diversity of fish at 34 sampling sites in twenty-four tributaries of the Sinos River basin; 2) quantify impact level by the Shannon-Wiener diversity index and an adapted Index of Biotic Integrity (IBI); and 3) check the interference of environmental impacts, formerly quantified in a Stream Corridor Assessment Survey (SCAS), on the fish assembly and 4) compare the relationship between the IBI with stream order. Fish sampling was performed by electric fishing in the period from April 2004 to August 2006. A total of 4,869 individuals were sampled, representing 61 species, 14 families and six orders. Significant relationships of the Shannon-Wiener index and IBI with SCAS scores and stream orders were found. Of all impacts that make up the SCAS score, only channel modifications were significantly correlated with IBI. These results indicate that the adaptation of the IBI was effective and performed better than the Shannon-Wiener diversity index when related directly to specific impact categories. The application of the IBI with the SCAS and the other variables was efficient in the tributaries of the Sinos River basin because it showed the biotic degradation in accordance with changes in physical habitat.

Abstract ObjectiveThe objective of this study is to assess gender representation in food and beverage print advertisements.ResultsThe study follows a quantitative descriptive approach. Using a content analysis technique, we assessed the gender representation in 200 food and beverage print advertisements found in corner stores located in four areas around schools in Lima, Peru, and Guatemala City, Guatemala (100 advertisements per country). A total of 36% of the ads exhibited a male main character for the case of Guatemala, while in Peru 14% of the ads presented a male main character. Furthermore, in Guatemala, 22% of the main characters were male animated characters. Moreover, 27% of the ads in Guatemala and 17%, in Peru were visually male-oriented. Overall, male characters appeared alongside sports references and in varied settings, whereas female characters were usually holding or consuming the product. In conclusion, although the majority of variables used to assess the representation of gender in food and beverage print advertisements were gender-neutral, those showing gender representation were mostly male-oriented. Despite its limited findings, the study provides evidence for the formulation of public policies and educational content aimed to protect children’s and adolescents’ health from the effects of food marketing.

Setiawan Y, Rachmawati R, Tarno H. 2018. Diversity of ambrosia beetles (Coleoptera: Scolytidae) on teak forest in Malang District, East Java, Indonesia. Biodiversitas 19: 1791-1797. Ambrosia beetle plays an important role in the temperate forest. Ambrosia beetle lives symbiotically with microorganism such as fungi, bacterium, and yeast that can cause plant wilt and death. In Java, ambrosia beetle has been reported to attack teak plantations in some regions. This research aimed to investigate the diversity of ambrosia beetles in the teak plant on monoculture and polyculture system in Malang District. This research was conducted in the teak forest in Dampit and Sumbermanjing Wetan, Malang District from March to May 2017. Ambrosia beetles were trapped by using baited bottle trap with 95% ethanol. The diversity of ambrosia beetles trapped was analyzed using Vegan package in R program to calculate the Shannon-Wiener diversity index (H), Species Evenness index (E), and Simpson's dominance index (D). The results showed that ambrosia beetles trapped in monoculture and polyculture teak plants system consist of nine species, i.e., Xylosandrus crassiusculus, X. morigerus, X. compactus, Xyleborus perforans, Euwallacea simillis, Xyleborinus andrewesi, Premnobius cavipennis, Coccotrypes distinctus, and Hypothenemus hampei. The Shannon Wiener index of Ambrosia beetles in polyculture (H=1.40) was higher than in monoculture (H=1.30), and both locations were categorized in the medium diversity category. The Species Evenness index of ambrosia beetles in polyculture (E=0.67) and monoculture (E=0.66) were also categorized in medium category. The Simpson’s dominance index in both locations was categorized in the middle dominance species. X. crassiusculus was the dominant species in polyculture and monoculture teak plant system.
