The diversity of dragonflies (Order Odonata) as a bioindicator of environmental quality has not been widely studied in the West Lombok region. This study aimed to determine the species diversity of dragonflies (Order Odonata) found in Batubolong River, West Lombok District and its relation to the occurring land cover changes. This study was carried out by using a descriptive explorative method, where the sampling technique was done by means of line transects. Maps of study and sampling locations as well as land cover changes were made using ArcGIS 10.4.1 software based on primary and secondary data. The results showed that there were 11 species of dragonflies with a Shannon-Wiener diversity index value (H') of 2.212 (medium diversity), a population density index (C) of 0.126 (low dominance), and a species evenness index (E) of 0.923 (high uniformity). Our study also found two rare species of dragonfly in Lombok Island i.e., 3 individuals of Nososticta emphyla (Lieftinck, 1936) with 9% relative abundance and 1 individual of Drepanosticta berlandi (Lieftinck, 1939) with 3% relative abundance. The discovery of D. berlandi in Lombok is the third time after the findings in 1896 and the 19 th century. Analysis of satellite data around the sampling area within the period 2013-2020 showed that there has been an increase in land cover of 6,149.29 m 2 . The increase in land cover changes may have caused the disappearance of several Odonata species in the sampling location.","PeriodicalId":38783,"journal":{"name":"Biotropia","volume":"3 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-08-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75611559","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the approach is hampered by poor quality and quantity of DNA amount, and therefore, a pilot study is required. Our current short communication article reports the first noninvasive genetic sampling approach using feces of critically endangered Bawean deer ( Axis kuhlii ) to test the effect of aging on the amount of DNA extraction. Fecal samples of the Bawean deer were collected from the Bawean Deer Captive Unit in Sangkapura Village, Bawean Island, East Java. The samples were grouped into two different categories, namely: 1) New samples: for feces that had just been expelled for less than a day and 2) Old samples: for feces that were estimated to have been expelled for more than a day. There were 11 New samples and 16 Old samples. The samples were extracted using the QIAGEN Mini Stool Kit. The DNA quantification was carried out by using a fluorometer. The results of the extraction between the two categories were analyzed by the Kruskal Wallis test. The results showed that the mean rank value of the New samples was better (15.27) than the Old samples (13.13). The P value of the Kruskal Wallis test, however, was higher than the Asymp significant value, indicating that there was no meaningful differences (P = 0.49) between the two samples categories. The work described in this short communication article is a preliminary result and an important step in the study of Bawean deer population genetic.","PeriodicalId":38783,"journal":{"name":"Biotropia","volume":"11 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-08-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90527930","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Females in the reproductive period need good quality and quantity of food to provide nutrition for the fetus, milk production and child care. The mother will adapt to changes in behavior patterns and food type to meet these needs. The influence of parity and environmental conditions can affect the behavior patterns of females. During pregnancy, the Macaca nigra is known to have different proportion of activities in each period, while the behavior during the lactation phase in each mester is unknown. Therefore, this study aimed to analyze the behavior patterns in each mester and the food selection of Macaca nigra during the pregnancy and lactation phases, as well as the influence of female parity and environmental toward the behavior patterns. There were 39 females Macaca nigra observed from two groups from August 2018 to July 2019. An instantaneous focal sampling method was performed to observe females’ daily activities, continuous focal sampling to monitor food types and a selectivity index to analyze food type preferences. The results showed that the female Macaca nigra pattern was influenced by the reproductive phase, female parity and environmental conditions. Females at the end of the pregnancy and lactation phases had a high proportion of feeding and eat more arthropods. Primiparous females mostly performed resting activities. Food preference was influenced by reproductive factors and food availability. The choice of fruit could be affected by fruit availability, and their favorite food was D. mangiferum and Euginia sp.","PeriodicalId":38783,"journal":{"name":"Biotropia","volume":"10 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-08-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85600965","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The purpose of this study was to determine the community structure of benthic foraminifera community, sediment types and the relationship between the abundance of foraminifera with the sediment types in the eastern waters of Segara Anakan Lagoon in Cilacap. Method used in this study was a survey method. Samples were taken by using random sampling method. The study was conducted at 5 stations with 3 repetitions. Laboratory observations carried out included the types and numbers of benthic foraminifera. Community structure of foraminifera among stations were analyzed using one-way ANOVA, while the relationship between community structures and water quality parameters was analyzed using Pearson correlation. The results showed that in the the eastern waters of Segara Anakan Lagoon there were 58 species of foraminifera which abundance ranged from 532 ind/m 2 to 927 ind/m 2 . The diversity index of foraminifera was in the medium to high diversity categories. The uniformity index of foraminifera was in the high uniformity in a stable community. The dominance index of foraminifera was in the low category. The sediment types was fine sand, medium sand and coarse sand. The relationship between the abundance of foraminifera with the sediment types was strong with high R values (0.763-0.809).","PeriodicalId":38783,"journal":{"name":"Biotropia","volume":"34 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-08-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90570787","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The purpose of this study was to determine the density and diversity of neuston as a bioindicator for water quality in the lake and waterfall. The methods used were survey and observation. The study was carried out by using purposive sampling at two locations, namely the lake and waterfall of Situ Gunung, Sukabumi, with a sampling area of 1 x 1 m2. The samples obtained were put into bottles containing 70% alcohol to be identified in the laboratory. Environmental parameters measured were air and water temperature, water pH, water depth, turbidity, water flow velocity, dissolved oxygen, substrate and weather conditions. The results obtained indicated that the lake and waterfall of Situ Gunung, Sukabumi had highest neuston densities were shown by Gerrir bcustris and Dineutus assirnilis. The lowest neuston densities were shown by Metrobates hesperius, Gemis cornatus, Aquarius remigs and Trepobates pictzls.
