Understanding the impact of munia birds (Aves: Passeriformes: Estrildidae) on rice farming: Behavior, distribution, and bioacoustic parameters. Biodiversitas 25: 186-196. Munia birds represent a significant challenge in rice farming. This study investigates the role of Munia birds (Aves: Passeriformes: Estrildidae) within rice agroecosystems. Utilizing point count observation methods in Desa Rowosari, Jember, across two farming models (organic and conventional), we assessed the behavior, population distribution, and bioacoustic parameters of Munia species. A total of 3820 Munia individuals were documented: 2187 Javan Munia (Lonchura leucogastroides Moore, 1858), 1214 Scaly-breasted Munia (Lonchura punctulate Linnaeus, 1758), and 419 White-capped Munia (Lonchura ferruginosa Sparrman, 1789). Bioacoustic recordings were conducted using the TASCAM DR 60D recorder, complemented by statistical tests in SPSS 16.0 and visual data representations via Matplotlib and Seaborn libraries. Findings revealed that Munias inflict damages ranging from 10.85% to 30% on rice crops. Notably, JM's bioacoustic bandwidth displayed adaptability between organic and conventional cultivation environments (P value=0.0129). In terms of population distribution, SbM has the highest population density on conventional (density=22.38), JM has the highest density on organic (density-32.55). Passing through activity is more observed in both types of organic and conventional management models. Scaly-breasted Munia dominates in three time groups, both in the morning (x ?= 224.75), mid day (x ?= 163.75), and afternoon (x ?= 198.25). However, PCA depiction indicates that the activity of passing through is dominated by JM. JM and SbM are depicted gathering in the center, indicating a similar average relationship between populations. While Munias pose potential threats as pests, their absence could surge insect populations, underscoring their ecological significance. This study accentuates the importance of an informed management strategy, considering Munia's multifaceted impact on agroecosystems.

The landscape of this Islamic boarding school is designed to contribute to the preservation of the surrounding environment. This study aims to determine plant diversity and behavioral patterns in environmental conservation in Pabelan Islamic Boarding School, Magelang District, Central Java, Indonesia. Vegetation analysis was conducted by inventory of tree species planted in the area of the school. Analysis of the behavior patterns was carried out using observation, interviews with the clerics (kiai), teacher (ustaz) and staff, and questionnaires to students. The result of vegetation analysis showed that Pabelan Islamic boarding school has a moderate level of flora diversity with a Shannon-Wiener index (H’: 2.597). This is because the management of the school has a unique way of maintaining flora biodiversity by requiring every new student to bring unique or rare plant seeds from their hometown. The Kiai and teacher at the school have progressive thoughts about the human's relationship with God and nature. Human is God's representative who is obliged to maintain the environment and natural elements including biodiversity. The students generally have adequate awareness and concern for the environment and sustainability which is largely influenced by the figure of the Kiai. The findings of this study imply that Islamic boarding school (pesantren) can play essential role in practicing and raising awareness of sustainable environmental management and biodiversity conservation.","PeriodicalId":8801,"journal":{"name":"Biodiversitas Journal of Biological Diversity","volume":"66 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140459290","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}

There is limited knowledge regarding the genetic connectivity and diversity of the Red Snapper (Lutjanus gibbus Forsskål, 1775) populations that inhabit Papua Waters, Indonesia. Thus, the current study attempted to ascertain the genetic characteristics, level of diversity and genetic connectivity of the L. gibbus population. We conducted genetic research on 38 L. gibbus specimens from five different places in Papua Waters. We analyzed the L. gibbus genetic characteristics, diversity and genetic connectivity using the Cytochrome C Oxidase subunit I (COI) gene as the genetic marker. There were 15 polymorphism sites in the COI gene sequence among L. gibbus individuals. Polymorphism occurs due to transversion and transition mutations. The COI gene fragment was translated, producing 188 amino acids composed of 19 different amino acids. A total of 13 distinct haplotypes were detected among the L. gibbus population residing in Papua Waters. The haplotype diversity (Hd=0.740) and nucleotide diversity (Pi=0.002) were relatively medium. The genetic structure study indicated that the 5 populations of L. gibbus in the Papua Waters had little genetic differentiation, as evidenced by a Fixation Index (Fst) of 0.018 (P-value 0.35386±0.01443). Based on this, the management of Red Snapper resources at these 5 locations must be carried out as a single unit.","PeriodicalId":8801,"journal":{"name":"Biodiversitas Journal of Biological Diversity","volume":"109 ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140459540","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}

Ecosystem carbon stock and annual sequestration rate from three genera-dominated mangrove zones in Benoa Bay, Bali, Indonesia. Biodiversitas 25: 287-299. The mangrove ecosystem is an ecologically productive wetland system that serves as a carbon sink. However, various factors have contributed to the variation in values when calculating ecosystem carbon stock and the sequestration rate in the mangrove ecosystem. The presence of varying environmental conditions has resulted in the categorizing different species of mangroves, which may lead to variations in ecosystem carbon stock and sequestration rates. In this study, we aim to assess the ecosystem carbon stock and sequestration rate of the mangrove ecosystem in Benoa Bay, Bali, Indonesia. The ecosystem has been categorized into three zones based on the dominant genera: Bruguiera, Rhizophora, and Sonneratia. This research aimed to investigate the influence of mangrove zoning on the variability of carbon stock values and sequestration rates within the ecosystem. The allometric calculation technique and net primary productivity and soil organic carbon percentage values obtained using the Loss on Ignition (LOI) method are used to estimate each zone's ecosystem carbon stock and sequestration rate. The findings of our study indicate that there are notable variations in the carbon stock of ecosystems across different zones. However, we did not observe any substantial changes in the annual carbon sequestration rates. The Sonneratia zone exhibits the maximum value of ecosystem carbon stock and sequestration rate (1,570.9±248.0 tCO2ha-1 and 81.8 tCO2ha-1yr-1), while the Bruguiera zone demonstrates the lowest values (1,029.6±130.9 tCO2ha-1 and 75.6 tCO2ha-1yr-1). The three zones' average carbon stock and sequestration rate are estimated as 338.2 tCha-1 (1239.9 tCO2ha-1) and 21.5 tCha-1yr-1 (78.9 tCO2ha-1yr-1), respectively. In total, the carbon storage and absorption capacity of Benoa Bay amounts to 421,149 tC (equivalent to 1.5 million tCO2), with an annual rate of 25,769.4 tCyr-1 (equivalent to 94,573.6 tCO2yr-1).

Kepulauan Seribu National Park has several types of commercial sea cucumbers (Echinodermata: Holothuroidea). Many local and foreign communities take sea cucumbers from nature without paying attention to habitat conditions. This phenomenon causes a decrease in the availability of sea cucumbers. This research was carried out to help stabilize the sea cucumber ecosystem and its availability to be considered for its sustainability. This research was conducted in May-June 2023, at Kelapa Dua Island and Panjang Kecil Island in the Kepulauan Seribu National Park, Jakarta, Indonesia. Sampling was carried out using the field observation method, where the location points were determined by adjusting where the sea cucumber habitat was located. Sampling points were carried out on two islands, each island was assigned 4 station points, with the total number of stations on both islands being 8 station points. Sampling was carried out using perpendicular transect lines, divided into 3 zones. The data analyzed includes the Index of Diversity, Evenness, Dominance and Density. Based on the results 12 species were obtained from both islands, with the genera Holothuria, Stichopus, Bohadschia, Actinopyga, and Synapta. The highest density is at station 3 Kelapa Dua Island, with a density value of 0.57 (ind/m2), and the lowest density is at station 1 Panjang Kecil Island with a value of 0.14 (ind/m2). The results show a moderate diversity value, a low Dominance value, and a small evenness value, while the water quality result value can be said to be good because it has a value according to the survival quality standards for sea cucumbers in marine waters.","PeriodicalId":8801,"journal":{"name":"Biodiversitas Journal of Biological Diversity","volume":"68 ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140459820","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}

This study aims to determine the estrous characteristics and steroid concentrations during estrus in Aceh cattle after estrus synchronization using prostaglandin F2a. This study involved 9 Aceh cows with good reproductive status, not pregnant, and has shown at least 2 regular cycles, which were divided into 3 treatment groups. The first group (GI) received a single injection treatment, the second group (G2) received a double injection treatment with an interval of 10 days, and the third group (G3) was also treatment double injection with an interval of 12 days. Symptoms and responses to estrus were reported descriptively, and the data collected on onset, intensity, and duration of estrus were analyzed using one-way analysis of variance followed by Duncan's test. The results showed that estrus symptoms were almost similar and estrus response was 100% in all three treatment groups. The onset of estrus in G1, G2, and G3 did not differ significantly (P>0.05) with values of 68.00±18.33, 60.00±0.00, and 72.00±24.00 hours, respectively. The intensity of estrus in G1, G2, and G3 showed significant differences (P<0.05) with scores of 3.00±0.00, 5.00±0.00 and 4.33±1.15, respectively. The duration of estrus showed no significant difference in G1, G2, and G3 (P>0.05) with durations of 32.00±18.33, 72.00±0.00, and 52.00±38.57 hours, respectively. The concentrations of estradiol and progesterone obtained also showed no significant differences (P>0.05) in G1, G2, and G3, with respective concentrations of 91.67±24.77, 132.00±23.15, 89.47±24.19 pg/mL and 0.98±0.59, 0.86±0.18, 1.00±0.17 ng/mL. In conclusion, estrus synchronization with PGF2a single injection and double injection in Aceh cattle was found to have 100% estrus response. However, PGF2a with double injection showed higher estrus intensity compared to single injection. In Aceh cows, the recommended protocol for estrus synchronization using PGF2a is double injection.","PeriodicalId":8801,"journal":{"name":"Biodiversitas Journal of Biological Diversity","volume":"48 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140460187","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}

Organic matter is a crucial factor influencing mangroves' structure and species composition. The present study aimed to assess and compare the organic matter content in the sediment of Pulau Dayang Bunting and Sungai Kilim mangroves ecosystem in Langkawi, Kedah. The spatial variation of the organic matter contents was measured from the sediment at different zones in a line transect at each location. The mean of organic matter content recorded in the Pulau Dayang Bunting mangroves community was recorded from 13.67% to 15.74% and 13.06% to 16.57% in the Sungai Kilim mangrove community which were classified in the medium category. Results of Two-way ANOVA analysis revealed significant differences in the organic matter content between mangroves communities and only organic matter content in Station 2 was significantly different at the lower, middle, and upper zones (ANOVA one way, P<0.05). Only salinity has a negative correlation with the organic matter content in the study area (r (34) = [-0.41], p = [0.014]). The upper zones exhibited a greater concentration of organic matter due to enhanced accumulation facilitated by the vertical water mixing. Mangroves age, vegetation density, salinity, and sediment types are also crucial factors in maintaining organic matter content in the mangrove ecosystem.","PeriodicalId":8801,"journal":{"name":"Biodiversitas Journal of Biological Diversity","volume":"108 ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140460418","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}

This experiment aimed to determine the ability of trembesi (Samanea saman Merr.) seedlings inoculated with AMF (Glomus manihotis) to reduce Pb from gold mine tailings media. Therefore, using plants and Arbuscular Mycorrhizae Fungi (AMF) is an alternative choice that can be considered to support a phytoremediation program to reduce Pb contamination in tailing areas. The experiment was conducted using a completely randomized design in a greenhouse with two factors, i.e., with and without AMF, and four different Pb treatments (0, 0.5, 1, and 1.5 mM). AMF-inoculated seedlings were grown on tailings media and exposed to Pb in different concentrations for 5 weeks. The results showed that the seedlings were still able to grow on the media with Pb up to 1.5 mM with a tolerance index of 91.6%. AMF induced the plant to accumulate Pb dramatically higher, even though this absorption tended to reduce plant biomass. Root tissue stored significantly higher Pb than stem and leaf tissue, with an average concentration was 526.29 mg/kg in the roots of mycorrhizal seedlings. The bioaccumulation level of Pb in mycorrhizal seedlings was significantly higher. The value of the transport factor was below 1, indicating that S. saman seedlings carried out the phytostabilization. The interaction of AMF with S. saman has a big potential to be applied in efforts to remediate Pb in tailings.","PeriodicalId":8801,"journal":{"name":"Biodiversitas Journal of Biological Diversity","volume":"55 18","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140459557","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}

Coastal greenbelts, comprise mangroves and beach forest trees, are pivotal in disaster mitigation and climate change resilience. Despite the evident importance of these coastal ecosystems, they are often overlooked in research due to a lack of comprehensive data on species community structure and their broader ecological importance. Hence, this present study was conducted to document beach forests composition and conservation status in selected coastal municipalities of Surigao del Sur, Philippines. The study was conducted in five sampling locations, namely, La Paz, Bil-at, Balibadon, Poblacion Cagwait and Arangasa Island. At each sampling location, a 2 km transect line, parallel to the beach’s shoreline, was established having a 100 square meter sampling plots spaced 50m apart. Beach species frequency counts, percentages, and diversity indices were quantified. The study documented 27 beach forest species belonging to 21 families and 25 genera with the dominant species being Crinum asiaticum, Cocos nucifera, Millettia pinnata, Timonius compressicaulis, and Terminalia catappa. Both Arangasa Island and La Paz beach forests have the highest species diversity (H’ = 2.04); however, Cagwait has the highest species richness (Margalef = 2.34). This study has potential to significantly contribute in addressing existing data gap regarding beach forest species in the Philippines.
