Many plants have the potential to be medicinal from the herbaceous group. Herbaceous plants have short, small steam and have a wet trunk because they contain many water and non-woody. This research aims to inventory species of herbaceous plants that can be medicinal plants and other uses in three different locations. The results showed that 12 species were found in the slope area, 340 individuals. The highest number of SDRn of 29.26% was Nephrolepis biserrata (SW.) Schott. In the ramp, the area has been found of 11 species of herbaceous, 215 individuals. The highest number of SDRn of 34.81% was Phrynium pubinerve Blume. In a hill, area has been found 16 species of herbaceous, 542 individuals. The highest number of SDRn of 38.72% was Phrynium pubinerve Blume. Dominance index (C) in three locations research was 0.26, 0.23 and 0.31. Similarity index (ISs) in three locations was 60.87% (slope-ramp: high), 59.26% (slope-hill: medium) and 57.14% (ramp-hill: medium). There were 11 species as medicinal plants, 17 species as ornamental plants, and 2 species as crafts.

Tanjung Luar is coastal water used as a waste disposal area for Fish Landing Based (FLB) activities. However, the condition of the waters with phytoplankton as a bioindicator has never been reporting. This research aims to know Bacillariophyceae in terms of abundance, diversity, and measurement of environmental pollution variables. Methods Sampling at the study location was determined by a systematic random sampling method. Data analysis Bacillariophyceae were determined using formula abundance, diversity index, and dominance index. The index of similarity of species between sample points was determined based on the Bray-Curtis Cluster Analysis. Furthermore, the results showed an abundance of Bacillaryophyceae of 322,000 individuals / L classified as low, the diversity index of Bacillariophyceae of 2.162 classified as moderate, and a dominance index of 0.138 (without dominating species). The results showed that the highest species similarity index was between sample points II and III (57.9%), and the lowest species similarity index between sample points I and II was 23.7%. Water pollution on the waters of PPI Tanjung Luar is classified as moderate pollution level and oligotrophic fertility.

Abstract. Munawaroh E, Yuzammi, Purwanto Y. 2020. The Euphorbiaceae (Spurge Family) in Bogor Botanic Gardens, Indonesia: Diversity, conservation and utilization. Biodiversitas 21: 5021-5031. Euphorbiaceae (Spurge family) is the fourth largest family world-wide, consists of 1,354 species and 91 genera. The family is also a part of the Bogor Botanic Gardens collections. The Gardens has evolved to fulfill its mission through five principal functions: conservation, research, education, tourism, and environmental services. The aims of this study are to reveal the diversity, conservation, and its potential in the Bogor Botanic Gardens. This research was based on direct observation of all members of Euphorbiaceae family in the Gardens, as well as Registration Unit and the Garden’s catalog which were observed for more than 10 years. The Gardens collected 39 genera, 71 species, and 136 specimens where 91 specimens are trees, 38 specimens are shrubs, three specimens are climbers and four specimens are succulents. Most of the collections are native to Indonesia 75.91% (103 specimens) and only 33 specimens (24.09%) from overseas. Amongst native collections have dominated from Jawa 25.54% (34 specimens), Sumatra 24.08% (33 specimens). The others are from Sulawesi 9.48% (13 specimens), Kalimantan 7.29% (10 specimens), Maluku 6.56% (9 specimens), Papua 2.28% (three specimens), and Nusa Tenggara Timur 0.72% (one specimen). Many species of the family have potentially developed as traditional medicinal plants (11 species), ornamental plants (16 species), spices and vegetable (two species), timbers (14 species), rubber plants (one species), source of energy (two species) and toxic (six species). Several old collections have retained at the Gardens that aged over 75 years, such as Mallotus philippensis (Lam.) Mull. Arg. forma mollis, Acalypha wilkesiana Mull. Arg., Acalypha hispida Burm. var. sanderi (N.E.Br.) J. J. Sm., Acalypha wilkesiana Mull. Arg. forma Montana, Sapium aucuparium Jacq. and Ricinodendron heudelotii (Bail.) Heckel. A map of planting point of the Euphorbiaceae collections is provided.

Gastropods plays an important role in the food chain on seagrass ecosystem and its existence are depend on the physical-chemical factors in the seagrass ecosystem. This study aims to determine the density and diversity of gastropods associated in seagrass habitat in Nusi and Gersen coastal waters. The measurement results of some physical-chemical waters variables, are still quite good for the life of gastropods. Species composition of gastropod in Nusi at higher than at the Gersen, but instead of individual density in Gersen more higher than Nusi. Diversity index of gastropods at Nusi station is higher (3,757) than Gersen (3.053), on the contrary the eveness and dominance index are higher at Gersen station than Nusi station. Community similarity index by species is low between the two stations, which indicates that the species of gastropods at both stations is quite different. The influence of human activity and higher utilizatin of gastropods in Nusi has lowered the density of gastropods in seagrass habitat, so it needs awareness efforts on the importance of gastropods and the seagrass habitat for coastal ecosystem.

The fish assemblage structure in Al-Huwaizah marsh, southern of Iraq was assessed. Fish samples collected monthly by different fishing means from period December 2017 to November 2018. A total of 28959 individual of fish belonging to 9 families and 19 species were collected, 11 of them of native species and 8 of alienspecies. The numerical dominance index value (D3) of the highest three abundant species comprised 74.26% of the total fish caught, included Planiliza abu (Al-Keshny) 38.2% ; Coptodon zilli (Tilapia red abdomen) 29.41% and Carassius auratus (Prussian carp) 6.65%. The total weight of fish caught 2,190,680 tan, highest weight 312,242kg achieved in July, while lowest weight 41,590 kg found in September. The weight dominance index value (D3) of the highest three species in weight recorded 1,409,973 tan of the total weight of fish caught included C. zilli(Tilapia red abdomen) 659,994 kg , S. triostegus (Jerry fresh water) 495,784 kg and O. aureus (Blue tilapia) 245,195kg.The annual rate value for diversity, richness and evenness indices amounted 1.88, 1.75 and 0.64, respectively. Some of physical and chemical properties were studied such as water temperature which ranged from 11.5°C in January to 31.02°C in August month, dissolved oxygen ranged from 2.24 mg/l in September to 9.9mg/l in February, salinity varied from 1.37‰ in November to 3.76‰ in September and pH which ranged from 7.4 in June to 8.15 in December.Jaccard Similarity Index (Ss%) was used to know the similarity degree between the monthly catch samples. Also associations between distribution of fish species and the environmental variables were quantified by using canonical correspondence analysis (CCA).
