Biodiversitas 24: 3128-3139. The Komodo dragon (Varanus komodoensis Ouwens, 1912) is a big lizard species from the Varanidae family that belongs to the Endangered category (EN) listed on the IUCN red list and Appendix I CITES. This study aimed to reveal the distribution of potential preys Komodo dragons in Rinca Island, Komodo National Park, Manggarai District, East Nusa Tenggara, Indonesia, using Maximum Entropy (MaxEnt), which was collected using rapid assessment methods. The presences of the Komodo dragon's potential prey come from direct and indirect observation or previous studies. We collected 510 points of Komodo dragon prey presence in Riung, Ngada District, East Nusa Tenggara, Indonesia from six species, including cattle, but only used 127 points for analysis based on the correlation. Long-tailed macaque, wild boar, civet, Timor deer, feral horses, and cows were the potential prey for komodo in Riung. Most of the points come from cattle, such as cows. On the other hand, we used environmental habitat to represent prey habitats such as elevation, slope, land surface temperature, moisture index, vegetation index, and distance from specific objects such as distance from agriculture, rivers, road, savanna, and settlement. Komodo dragon's potential prey in Riung was distributed in savanna, mangrove, and lowland forest. The result showed three suitable habitats for the Komodo dragon's potential prey dominated by low and moderate-suitability areas.","PeriodicalId":8801,"journal":{"name":"Biodiversitas Journal of Biological Diversity","volume":"62 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83034447","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}

Sumatra Island is recognized as the distribution center of tropical fruit species in Indonesia. However, increased human activity threatens the existence of edible wild fruit plants in nature. The study aims to assess the diversity and regional conservation status of wild edible fruit plant species in Sumatra, Indonesia. The study was conducted in four provinces: West Sumatra, Riau, Jambi, and Bengkulu. For the sampling, a modified line transect method was used. A total of 331 wild edible fruit plant species at four studied sites in Sumatra consisted of 73 families. The highest number of fruit plant species was recorded in West Sumatra Province, i.e., 176 species, followed by Jambi (172 species), Riau (121 species), and Bengkulu (76 species). The diversity of wild edible fruit plant species was higher in West Sumatra Province (3.85) but lower in Riau Province (3.25). Artocarpus integer (Thunb.) Merr., Baccaurea lanceolata (Miq.)

The observation of collected Sapu-sapu fish samples from three major Mataram rivers. Duck eggs and meat were collected from a livestock group that fed Sapu-sapu fish. The observed variables include; macronutrients (moisture content, crude protein, crude fat, crude fiber, and ash) and heavy metal content (Cu and Pb) in the Sapu-sapu fish, duck meat and eggs fed by Sapu-sapu fish. The study found that the Sapu-sapu fish possesses complete macronutrients, making it a possible duck feed. The heavy metal content of copper (Cu) in the Sapu-sapu fish ranges from 189.314±0.0238 ppm, while the lead (Pb) content ranges from 4.25±0.18 ppm. The average heavy metal content of Cu in the eggs and meat of ducks consuming Sapu-sapu fish was 7.692±2.158 ppm and 14.523±6.481 ppm, while the levels of lead in eggs and meat of cesarean fish were 0.936±1.557 ppm 0.373±0.211 ppm. The study concluded that the Sapu-sapu fish in the Mataram city stream has a complete nutritional content (protein, fat, amino acids, minerals) but contains high heavy metals. Therefore, if consumed, ducks dispose of it into the eggs and duck meat. As a result, the eggs and meat of ducks that consume sapu-sapu fish contain heavy metals Cu and Pb that exceed the threshold, so they are unsafe for human consumption.\u0000","PeriodicalId":8801,"journal":{"name":"Biodiversitas Journal of Biological Diversity","volume":"2 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88810638","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}

Identification of Arbuscular Mycorrhizal Fungi associated with Arabica coffee root (Coffea arabica) in the Arfak Mountains region of West Papua, Indonesia. Biodiversitas 24: 3207-3213. Coffee is a global commodity widely consumed as a beverage globally and has a high economy. Currently, the trend of drinking coffee is no longer dominated by older people but has become part of the millennial and celebrity lifestyle; therefore, worldwide demand for coffee continues to increase. Efforts to develop area expansion and productivity continue to be pursued. The Arfak Mountains Region of West Papua, located 800 - 2,500 m above sea level (masl), is a potential area for coffee plantations. The local farmers in this area have grown coffee independently and with gradual government support for the last years. Given the benefits of Arbuscular Mycorrhizal Fungi (AMF), which can increase plant growth and productivity, this study aims to identify the types of AMF that are associated with coffee plants in 4 districts, Mokwam, Anggi Giji, Anggi Gida, and Membey in Arfak Mountains region, West Papua. Identification of AMF types was observed based on the morphology of mycorrhizal spores. The research was conducted using the observation method with a purposive sampling technique from November 2022 to March 2023. Based on the observation, the coffee plants in 4 districts were associated with AMF. The types of AMF associated with coffee in Mokwam were more numerous than in other locations, namely the Acaulosporaceae Genus with five species, Glomeaceae Genus with five species, one species of Simiglomus sensu stricto, one species of Funneliformis sensu stricto, and one species of Septoglomus sensu stricto. AMF in Anggi Giji District consisted of Acaulosporaceae Genus with two species, Glomeaceae Genus with four species, while in Anggi Gida District consisted of Acaulosporaceae Genus with one species, Glomeaceae Genus with three species, one species Septoglomus sensu stricto. AMF species in the coffee plants of the Membey District are the Acaulosporaceae Genus with three species, the Glomeaceae Genus with two species, and one species of Septoglomus sensu stricto. From the soil analysis results, the soil fertility level is low; conversely, the mycorrhizal presence level is higher because of the more infertile soil, the more active mycorrhiza.","PeriodicalId":8801,"journal":{"name":"Biodiversitas Journal of Biological Diversity","volume":"64 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84316878","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}

Therefore, this research aims to examine tropical climate change in South Sulawesi, Indonesia and analyze its impact on horticultural crops. Apost-positivistic interpretation framework of the case study tradition was used, while the location was determined by purposive sampling followed by comprehensive data collection. Data were analyzed using integrated techniques, and validity tests were carried outto assess thecredibility and reliability. The results indicated a local climate change marked by a differencein the pattern of distribution and intensity of extreme rainfall between 2015 and 2018. This was due toan increase in air temperature, which on average reached ±0.03731°C from the lowest of 22.50°C in 2011 to the highest of 23.12°C in 2020. In other words, it can be stated that the air temperature had increased by ±0.63°C in the last decade.

Diversity of woody plant nematodes in specially protected biocenosis of Zarafshan Mountain, Uzbekistan. Biodiversitas 24: 3145-3151. Very little information exists on nematodes' diversity and ecological characteristics in small artificial forests. This article provides information on the diversity of the nematode fauna, bioecological characteristics, and species distribution by biotopes of fruit trees growing in the biocenoses of the Omonkutan National Nature Park in the Western Zarafshan mountain range. As a result of the research, 62 species of nematodes were recorded in the nematode fauna of fruit trees. These species were analyzed taxonomically and ecologically. It was determined that the species in the fauna belong to two classes and five orders of the Nematoda type. They are divided into five large and several small groups according to their ecological characteristics. Among the ecological groups, omnivorous and plant-feeding nematodes are the dominant groups in terms of the number of species. The diversity of nematodes was high in the 0-15 and 15-30 cm soil layers. It turned out that the diversity in different biotopes is related to the ecological characteristics of nematodes. In particular, herbivorous nematodes accounted for 72.2% of nematodes in the root system. An increase in the diversity of nematodes was observed in the rhizosphere soil layers. A sharp increase in the number of species and individuals of omnivorous nematodes and bacteriotrophs was observed in the 0-15 cm soil layer, and this trend was also preserved in the 15-30 cm layer. The species richness and diversity (according to the Shannon and Simpson indices) were the lowest in vegetative parts of plants. As a result of the research, it became clear that the diversity of soil nematodes is completely dependent on their trophic characteristics.","PeriodicalId":8801,"journal":{"name":"Biodiversitas Journal of Biological Diversity","volume":"18 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77687654","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}
