Poulsen is a ginger endemic to Sulawesi, and there is no research on its essential oils. The Essential oil information of E. acanthodes is the first reported and has a high novelty. The objective of the study is to analyze the component of E. acanthodes essential oils, which are endemic to Sulawesi. The essential oils obtained by hydrodistillation of the leaves, stems, flowers, and rhizomes of E. acanthodes A.D. Poulsen. The samples were analyzed by GC-MS method using the Agilent Technologies 7890 Gas Chromatograph with Auto Sampler. Data analysis of essential oils of GC-MS results were determined based on comparing mass spectra from the NIST 2005 v.2.0 library and Wiley 7 library 2003. The oils of E. acanthodes contain terpenoids, phenolic, steroids, and other compounds. Phenolic compounds (39.56%) predominate in leaves, other compounds (41.25%) on stems, diterpenes hydrocarbons (77.3%) in flowers, and other compounds (43.5%) and steroids (40.4%) on rhizomes. The five main compounds of E. acanthodes are Neophytadiene; (+)-De-O-Methylcentrolobine; Cholest-5-En-3-Ol,23-Ethyl-,(3. Beta.23S)-; 9,12-Octadecadienoic Acid, Phenol, 2-ethyl-. The analysis found several compounds that can be used for industry and medicine in the future.

Karst is prone to damage and difficult to reuse, so it requires conservation efforts. One of the plant species that can maintain this sustainability is Ficus which acts as key species in karst ecosystems. However, at this time the species is experiencing disturbances, one of which is due to the experience of invasive plants that can threaten the existence of Ficus because the weeds can colonize habitats and are dominant which can change species diversity. This study aimed to analyze the diversity and distribution of Ficus, compare species composition, and analyze environmental factors that affect Ficus spp. in Pattunuang Resort and Bantimurung Resort. Vegetation analysis method with nesting plots placed by purposive sampling and supported with environmental and soil data measurements to determine the factors that indicate the habitat preference of Ficus. We found 18 plant species of Ficus spp. in total. At Resort Pattunuang we found 14 Ficus species with the highest abundance being Ficus sundaica (27.55%), while we recorded 15 Ficus species at Resort Bantimurung with the highest abundance being Ficus ampelas (29.23%). Ficus species were uniformly distributed with a relatively high ratio of species composition in both resorts. Principal Component Analysis (PCA) showed that the presence of Ficus in Pattunuang Resort is influenced by wind speed, soil temperature, air temperature, soil moisture, soil pH, and air humidity. In Bantimurung Resort, the existence of Ficus is influenced by wind speed, soil temperature, soil moisture, and air humidity.

Consequently, it is essential to carry out research and efforts to preserve dragonflies in urban areas. This study aims to provide information about the diversity and structure of dragonfly communities in various habitat types in the Lakarsantri, Surabaya. Data collection in this study was carried out in the habitat types of ponds, reservoir, river, and rice field in July to September 2021. The study results show there are 22 species from 4 families with a total of 827 individuals. Analysis of the Shannon-Wiener diversity index showed that the highest value of dragonfly diversity was found in a pond, with a value of H' = 2.40, and the location with the lowest value was a river, with a value of H' = 1.77. At four research locations that have different aquatic ecosystems, the community structure of dragonfly is also different. The composition of the dragonfly community structure at the reservoir location has similarities to a pond, and at a river location, it has similarities to a paddy field. Differences in abiotic factors consisting of light intensity, humidity, and temperature at each study location have a correlation with differences in dragonfly community structure. In addition, the composition of the vegetation at each location is also one of the factors causing differences in the structure of the dragonfly community.

Na indústria eles são utilizados na produção de enzimas, vitaminas, polissacarídeos, pigmentos, lipídios e glicolipídios, valiosos em biotecnologia. O Brasil possui grande diversidade biológica de paisagens, entre elas está a Caatinga, bastante explorada quanto ao potencial biotecnológico vegetal, mas com poucos estudos sobre o potencial dos microrganismos associados a esse bioma. Este estudo teve por objetivo avaliar a produção de enzimas de fungos isolados no solo associado a plantas do semi-árido. As amostras de solo foram coletadas na região da Grota do Angico, município de Poço Redondo, Sergipe, associadas a duas plantas características, Croton heliotropiifolius Kunth e Xiquexique gounellei. Foram isolados 39 fungos das amostras de solo e suas atividades proteolítica, amilolítica e pectinolítica foram avaliadas. Os 17 fungos associados à C. heliotropiifolius apresentam predominantemente atividade de proteases, sendo que apenas um deles apresentou atividade de pectinase, nos demais os resultados foram negativos. Por outro lado, um maior número dos 22 fungos isolados do solo associado à X. goiunellei, atividade enzimática e diversidade de enzimas, sendo que a maioria apresentou atividade proteolítica. Foi detectada atividade amilolítica em oito fungos, atividade proteolítica em 12 fungos e atividade pectinolítica em 6 fungos. Evidenciou-se o potencial dos fungos isolados do bioma da Caatinga para produção de enzimas, principalmente proteolíticas.

A quantificação de proteínas demonstrou que a mucilagem liofilizada tem teor proteico maior do que em folhas frescas de ora-pro-nobis, apresentando média de 39,55 % de proteínas.
