Checklist of the earthworm fauna of Uzbekistan (Oligochaeta: Lumbricidae). Biodiversitas 24: 4392-4401. This article presents a checklist of the earthworm fauna (Lumbricidae) of Uzbekistan based on published records and the authors' data. This is the first checklist for Uzbekistan, which contains complete information on the ecological category, habitat, type of distribution and distribution of 28 species of earthworms in 4 regions of Uzbekistan. The currently known, based on our research, earthworm fauna of Uzbekistan, includes 23 species, 5 subspecies belonging to 9 genera. Of them, 3 species (Perelia persiana, Perelia turcmenica, Lumbricus rubellus) are new to Uzbekistan. Perelia is the species-richest genus (12 species). These earthworms are distributed Kyzylkum desert region along river banks, in the mountainous regions of Pomiro Alai and Tien Shan biogeographic region, which is mostly covered with forest or autochthonous flora. The earthworm fauna is more diverse in forests of the northern and in the mountains of the southern parts of Uzbekistan. Literature data and our present study showed that there are no earthworms in the Ustyurt Plateau, due to the fact that the soils of the Ustyurt Plateau are gypsum, saline, and infertile.","PeriodicalId":8894,"journal":{"name":"Biodiversitas","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134948461","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}

Economic valuation of seagrass ecosystem in Maribojoc Bay, Bohol, Philippines. Biodiversitas 24: 4427-4435. The seagrass ecosystem is one of the most productive and precious ecosystems. In the Philippines, however, more data on the economic valuation of all seagrass ecosystem services must be collected. The study estimated the total economic value of the seagrass ecosystem, including use and non-use values. Resource user groups include municipal ?shers, gleaners, and tourism business operators. The sample size was determined based on the total number of resource users in Maribojoc Bay, Bohol, Philippines and using a confidence coefficient of 95% (P = 0.05). The total economic value of the seagrass ecosystem in Maribojoc Bay is PhP 52.8 million (US$ 1.1 million). Direct use values, or market benefits, are PhP 35.4 million (US$ 708 thousand), accounting for 67% of the total economic value. Indirect and non-use values, are PhP 17.3 million (US$ 346 thousand), accounting for 33% of the total economic value. On a per hectare basis, the economic value of the seagrass ecosystem in Maribojoc Bay is PhP 46,722 (US$ 934). The results of this valuation can be an input in decision-making to manage and conserve the seagrass ecosystem as well as maintain the economic security of Maribojoc Bay. The findings of this study are valuable for developing a comprehensive information management and decision-support system for the management and protection of the seagrass ecosystem. However, more research is required to evaluate the range of ecosystem services provided by seagrass ecosystems across the country, focusing on qualitative value attributions linked to the social-ecological dynamics of seagrass systems.","PeriodicalId":8894,"journal":{"name":"Biodiversitas","volume":"56 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134948627","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}

Morphological characteristics and variability of traditional starch forming coix (Coix lacryma-jobi var. ma-yuen populations from Mindanao Island, Philippines. Biodiversitas 24: 4382-4391. Adlay (Coix lacryma-jobi var. ma-yuen (Rom.Caill.) Stapf) is an underutilized crop in the Philippines with high potential. Characterization and elucidation of the available variability among the local adlay populations are essential information for its improvement and better utilization. The study aimed to characterize the qualitative morphological traits of 34 traditional adlay populations from Mindanao Provinces and assess diversity by the Shannon Index and similarity by multivariate clustering. Results showed that all populations shared the same morphotypes in five descriptors but were variable for the rest. Six populations showed intense leaf anthocyanin coloration, and 23 expressed upright growth habits. Three types of leaf blade colors were observed, while the intensity of anthocyanin coloration of culms was expressed in four types. Most populations had semi-pubescent or highly pubescent leaves, generally intermediate leaf orientation and non-glaucous leaves. Immature grains were generally light green but expressed four color types at maturity, mostly circular with furrows on the surface. Diversity Indices (H') ranged from low to high. Leaf blade pubescence, anthocyanin coloration of culm, and mature grain color had high H' values. Cluster analysis showed that the variability was narrow, where overall clustering achieved 0.50 similarity. At 0.65 similarity, three groups can be derived with three populations as outliers. Clustering can be attributed to the differences in seedling color, anthocyanin coloration, plant growth habit, immature grain color, mature grain color, and shape. The study established the morphological description of the qualitative traits of traditional Philippine adlay and assessed diversity to be generally intermediate, where populations can be clustered into subgroups according to the degree of morphotype similarities. Clustering, however, was not related to provenances. It is recommended to conduct further geographic germplasm sampling, marker-based characterization, and agronomic evaluation to dissect further the genetic diversity and crop potential of the local adlay populations.","PeriodicalId":8894,"journal":{"name":"Biodiversitas","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134948632","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}

Ginantra IK, Muksin IK, Joni M, Wijaya IMS. 2023. Diversity and distribution of crustaceans in the mangrove forest of Nusa Lembongan, Bali, Indonesia. Biodiversitas 24: 4533-4541. Research on the diversity and distribution of crustaceans in the mangrove forest of Nusa Lembongan, Bali, Indonesia was conducted from March to June 2022. Sampling was carried out using the quadratic method at seven mangrove forest sites. The identification of crustacean species is based on morphological characteristics, namely carapace color, claw shape, legs, and body size. Crustacean density was determined based on the number of individuals per unit area of mangrove forest, diversity was determined by the Shanon-Wiener Index, and crustacean distribution was determined based on the frequency of species presence in each square at the seven study sites. Environmental factors were also measured: Mangrove vegetation, substrate type, temperature, pH, and salinity. The results showed that 12 species of crustaceans were found, consisting of 10 species of crabs and two species of hermit crabs. Several species of crabs are quite dominant in the mangroves of Nusa Lembongan namely Sesarma pictum (De Haan, 1835), with a density of 7 individuals/5 m2, Uca tetragonon (Herbst, 1790) of 3.7 individuals/5 m2, Uca rosea (Tweedie, 1837) with a density of 2.5 individuals/ 5 m2, and Uca triangularis (A. Milne-Edwards, 1873) with a density of 2 individuals/5 m2. Environmental factors support the life of Nusa Lembongan crustaceans, namely the type of substrate, mostly muddy and sandy, diverse species of mangrove plants, both true and associated mangroves, water temperature 27.70-29.00°C, pH 6.88-7.15 and water salinity ranging from 27.83-31.53‰. Crustacean diversity is included in the moderate category with their diversity index. There are three crab species with moderate to frequent (absolute) frequency of presence, namely U. rosea (Fi: 57.15%), S. pictum (Fi: 71.43%), and U. tetragonon (Fi: 85.71%). These species are present in four to six mangrove forest sites.","PeriodicalId":8894,"journal":{"name":"Biodiversitas","volume":"84 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134948465","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}

Lindiani P, Sundawati L, Suwarna U. 2023. Effect of biophysical conditions on standing and soil carbon storage in various land uses in Gunung Mas, Central Kalimantan, Indonesia. Biodiversitas 24: 4493-4502. One of the human activities that accelerates climate change is degradation and deforestation, which can lead to new land use in the form of palm oil plantations and agroforestry. Both of these land uses have the potential to store carbon, which can be optimized if the influencing factors are known. This study aims to estimate the potential for carbon storage in palm oil and agroforestry plantations in Gunung Mas, Central Kalimantan, Indonesia, and to analyze the effect of biophysical conditions such as topography, soil fertility, and stand density on the potential for carbon storage. The research was conducted in palm oil plantations (POP) and agroforestry areas categorized as agroforestry with forestry and palm oil plantation commodities (AG-SS), as well as agroforestry consisting of forestry, palm oil, and fruit crops (AG-SSB). Sample plots were determined through purposive sampling with 30 plots for each land use. The research results show significant differences in aboveground carbon (AGC), soil organic carbon (SOC), and total carbon storage among the three land uses. The largest total AGC was in AG-SS (66.24 ton.ha-1), while the lowest AGC was observed in POP (48.15 ton.ha-1). The greatest SOC was recorded in AG-SSB (2163.21 ton. ha-1), followed by POP (1922.12 ton.ha-1) and AG-SS (1846.72 ton.ha-1). The highest total carbon storage was measured in AG-SSB (2223.36 ton.ha-1), followed by POP (1970.27 ton.ha-1), and the lowest in AG-SS (1912.96 ton.ha-1). Biophysical factors, including topography, soil fertility, and stand density, influenced carbon storage in each land use. Topography and stand density factors significantly influenced AGC, while soil fertility factors significantly affected SOC and total carbon storage in all three land uses.","PeriodicalId":8894,"journal":{"name":"Biodiversitas","volume":"33 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134969652","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}

Melon (Cucumis melo L.) is widely consumed as fresh fruit or juice, and therefore deeper analyses of fruit quality are needed for future breeding purposes. Breeders have a role in providing improved melon varieties that suit consumer ideotypes or preferences. This study aimed to (i) evaluate the performance of melon genotypes, (ii) estimate the correlation between quantitative traits, and (iii) determine the clustering among genotypes based on plant and fruit traits. This research evaluated 24 genotypes from inodorus, reticulatus, and makuwa groups that were carried out from March to June 2022 at a greenhouse in the Tajur experimental station of the Center for Tropical Horticulture Studies, Bogor, Indonesia. IPB HD 2-111 and IPB HD 2-100 had good quality based on soluble solids content, fruit shape, flesh texture, and rind color, and G30 was relatively superior on flesh thickness, fruit weight, and vitamin C. Based on the multiple regression analysis, it was known that petal width, petiole length, and days to harvest were significantly affected the proportion of fruit cavity width to the fruit diameter. The adjusted coefficient of determination (R2) was 0.569. Cluster analysis grouped 23 genotypes into three main clusters based on the neighbor-joining method.

Bioflocculants are biological compounds produced by different microorganisms with many applications for wastewater treatment as such become an important product in biotechnology and a consequence to be used in industries. The current study aimed to isolate, identify, and screen bioflocculant-producing bacteria from different sites in Basrah City in Iraq. The production of bioflocculants was enhanced by optimization of various cultural conditions such as (carbon source, nitrogen supply, pH, and inoculum sizes) which were estimated in terms of flocculating activity test. Four wastewater samples and oil- contaminated soil samples were collected. Twenty-one different bacteria were isolated from wastewater and soil. Eleven bacterial isolates showed flocculating activity values of more than 50 %. The results showed that two bacterial isolates were reported as the best bioflocculants-producing isolates with a flocculating activity value of 87.80 % and 81.38 % respectively, these two isolates belonged to Aeromonas simiae and Exiguobacterium profundum which identified by 16S rDNA gene sequencing. Four bacterial isolates were discovered and recorded as new strains in NCBI GenBank with the accession numbers OQ848055 (Escherichia coli strain ANABASR1), OQ848056 (Stutzerimonas balearica strain ANABASR2), OQ848057 (Bacillus jeotgali strain ANABASR3) and OQ848058 (Hydrogenophaga temperata strain ANABASR4). The maximum flocculating activity of 84.49% and 88% was reported for A. simiae and E. profundum respectively under optimum conditions (glucose as carbon source, (NH4)2SO4 as nitrogen source, pH= 7 and 5% inoculum size).

Deforestation continues in Indonesia even though many regulations and precautions have been taken. It most likely happened due to the less economic contribution from the forestry sector, which caused the conversion from forest lands to more profitable land uses. The forest area covers 125 million hectares (66%) of 190 million hectares of country land but contributes only about 0.60% of the Gross Domestic Product (GDP). An agroforestry scheme is promoted to increase the economic value of the forest to increase both the community welfare and the environmental quality. This study indicates that the best agroforestry commodities for social scenarios are durian, ornamental plants, and laying hens, with the highest potential profit of IDR.143,857,559 (USD.9,652)/hectare/month and 9.19 tons/hectare carbon stock. While for the economic scenario is jackfruit, ornamental plants, and laying hens with a potential profit of IDR.146,908,379 (USD.9,789)/hectare/month and 18.66 tons/hectare carbon stock. In comparison, the ecology scenario promotes nutmeg and ornamental plants with a potential profit of IDR 36,814,280 (USD.2,470)/hectare/month, with the highest of 56.12 tons/hectare carbon stock.

Numba S. 2023. Genetic diversity and its association with Phytophthora palmivora resistance in Durian (Durio zibethinus) using RAPD markers. Biodiversitas 24: 4542-4548. Durian (Durio zibethinus L.) is a popular tropical fruit that contributes significantly to regional economic value. Root and stem rot disease caused by Phytophthora palmivora has become a serious threat to the growth and development of durian. Indonesia has various local durian varieties that have the potential of resistant to P. palmivora. This study aims to analyze genetic diversity and its association with the resistance of durian to root and stem rot disease caused by P. palmivora using RAPD markers. Ten varieties of durian were compared with those of 2 wild species, namely D. kutejensis (Hassk.) Becc. and Boschia excelsa Korth.. The DNA profile analysis was performed by using 10 RAPD primers. Furthermore, cluster analysis was done using the NTSYS (Numerical Taxonomic and Multivariate Analysis System) ver. 2.0. Observation of the DNA profile (DNA banding pattern) showed that all the primers succeeded in producing amplified DNA fragments. Of the total 78 bands produced, 10 bands were considered monomorphic, while 68 bands (87.20%) were considered polymorphic. The high level of polymorphism causes a low level of similarity between varieties so that not all resistant varieties are grouped in the same cluster. This study found that the 1kb band produced by the OPA-2 primer was a potential gen associated with resistance to P. palmivora. It is suggested to carry out further tests on crosses of resistant and susceptible varieties.","PeriodicalId":8894,"journal":{"name":"Biodiversitas","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134969860","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}

One of the challenges faced in rehabilitating pine forests in conservation areas is the limited information on plant species capable of adapting to these ecosystems. This study aimed to analyze the diversity of tree species that grow and adapt to pine forests and the relationship of natural forests with the vegetation characteristics of pine forests. The research was conducted in pine forests bordering natural forests and far from natural forests using the sample plot method. The study recorded 44 species from 27 families of seedlings, 46 species from 21 families of saplings, 25 species from 18 families of poles, and 24 species from 17 families of trees. Accumulation of species from all growth stages recorded 83 species (76 local species and 7 cultivated species) from 39 families. Based on the species accumulation curve, pine forests adjacent to natural forests have more species than those far from natural forests. Individual and family density in pine forests adjacent to natural forests were also higher than the density of these two variables in pine forests far from natural forests. Furthermore, both the pine forest adjacent to the natural forest and that far from the natural forest, each has its own species peculiarities. The results indicate that the existence of natural forests has an important role as a source of biodiversity for the surrounding ecosystem. As an implication of this study, species that can grow to the level of poles and trees can be recommended as rehabilitation plants in the Pinus merkusii Jungh. & de Vriese forests in Gunung Ciremai National Park, Indonesia because pine is not a local species and the allelopathy it releases can reduce plant diversity.","PeriodicalId":8894,"journal":{"name":"Biodiversitas","volume":"204 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134969864","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}
