Abstract. Roesma DI, Tjong DH, Syaifullah, Nofrita, Janra MN, Prawira FDL,Salis VM, Aidil DR. 2023.The importance of DNA barcode reference libraries and selection primer pair in monitoring fish diversity using environmental DNA metabarcoding. Biodiversitas 24: 2251-2260. Environmental DNA (eDNA) metabarcoding has become an alternative method used for biodiversity monitoring of an ecosystem. The eDNA metabarcoding has advantages compared to the conventional method because it is non-invasive, quick, and requires less cost. However, the effectiveness of the eDNA method is highly dependent on the coverage of the DNA barcode reference and primerpair. A study using the eDNA method was conducted for fish biodiversity monitoring in Singkarak Lake. Two-liter water samples were collected using sterile bottle samples at each sampling site (five sites). The universal primers (Fish FI and Fish R1) used for Next-generation sequencing (GRIDION, Nanopore, Oxford Technologies). The study detected 152 fish species using eDNA metabarcoding. Ten species out of the 30 originally reported in Singkarak Lake were detected using eDNA metabarcoding. The low percentage of fish detected is thought to be due to several factors; incomplete/unavailability of freshwater fish DNA barcodes in Indonesia registered in the database repository, inappropriate primer pair selection, low DNA quality, and the absence of target species DNA in collected water samples. The results demonstrated the significance of correctly registering DNA barcodes to the database and appropriate primer pair selection to identify eDNA metabarcoding. This study provides recommendations using eDNA metabarcoding for monitoring in future work.

Abstract. Nurmiati N, Herwina H, Periadnadi P, Janra MN, Hidayat R, Edelwis TW. 2024. Exploration of natural microflora from stingless bee honey harvested from Limau Manis area, Padang, West Sumatra, Indonesia. Biodiversitas 25: 2908-2916. The natural microflora in stingless bee honey has been explored in three stingless bee species: Tetragonula laeviceps Smith, 1857; Heterotrigona itama Cockerell, 1918; and Geniotrigona thoracica Smith, 1857. This study aimed to identify and analyze the proportions of natural microflora in stingless bee honey. The study used a survey method, with data being descriptively analyzed and presented. The focus was on identifying microflora groups of bacteria and yeast in the honey from these three stingless bee species. Proteolytic bacteria Microflora types were identified based on the medium used: GPA+CaCO3 for acidic microbes, SMA for proteolytic bacteria, and ethanol+CaCO3 for acetic acid microbes. The pour plate method was used to count the microbes. T. laeviceps honey (pH 3.3, sugar level 45% Brix) contained a total of 163.6×104 CFU/mL microflora (161.6×104 CFU/mL bacteria and 2×104 CFU/mL yeast). In contrast, honey from H. itama (pH 3.4, sugar level 57% Brix) harbored a total of 156.7 x 104 CFU/mL microflora (155.7×104 CFU/mL bacteria and 1×104 CFU/mL yeast) and G. thoracica honey (pH 3.7, sugar level 70% Brix) contained 129.6×104 CFU/mL bacteria only. Acidic (A) and proteolytic (P) bacteria were observed in honey samples from T. laeviceps (A= 69.3×104 CFU/mL; P= 36×104 CFU/mL), G. thoracica (A= 53.6×104 CFU/mL; P= 40×104 CFU/mL), and H. itama (A= 67.0×104 CFU/mL; P= 38.6×104 CFU/mL). Acidic and proteolytic bacteria were present in all three honey samples. In conclusion, the microflora composition in stingless bee honey varies across species, with bacteria being the dominant group in all samples. The pH and sugar content of honey may influence the microbial load, indicating a possible link between honey properties and microbial diversity.

Abstract. Nurdin J, Aziz R, Nur L, Janra MN. 2025. Water quality assessment based on saprobic index of phytoplankton with emphasis on several potentially Harmful Algal Blooms (HABs). Biodiversitas 26: 890-899. The estuary is one of the most productive ecosystems on earth due to the accumulation of all materials, including nutrients, from the upstream to the downstream. This ecosystem also plays a role in habitat function for many living organisms, such as protists, bacteria, invertebrates, and vertebrates. However, this ecosystem may suffer from the accumulation of waste, which leads to pollution. This study aims to investigate and update the information regarding water quality based on the phytoplankton from the estuaries in Padang City, West Sumatra Province, Indonesia, and its potential as Harmful Algal Blooms (HABs). Sampling was conducted from November to December 2023 at six estuaries in Padang, and several formulas, such as diversity, equitability, dominance, Bray-Curtis, and saprobic indices, were used to analyze all of the data, respectively. A total of 130 species of phytoplankton belonging to five classes were identified, where Bacillariophyceae showed the highest diversity (98 species). Overall, the phytoplankton was moderate to highly diverse (2.95>=H' >=3.93), highly equitable (0.73>=EH>=0.93), low dominant species (0.03>=C>=0.11), and the highest similarity using Bray-Curtis occur between station 5 and station 6. At the same time, the Saprobic index was constant (X: 1.00). The pollution status at these estuaries could be considered light at the b-mesosaprobic or b-meso/oligosaprobic phase. In addition, 16 phytoplankton species were identified as HABs from these estuaries, including Alexandrium, Dinophysis, Prorocentrum, and Pseudo-nitzschia. Reducing the source of pollution from organic or non-organic materials, where the majority come from household waste disposal, may keep the health and quality of the rivers and estuaries in Padang

Abstract

This study evaluated the potential of avitourism in the vegetated areas of Universitas Andalas, West Sumatra, through a two-day birdwatching simulation and campus community perception survey. The simulation was conducted on 7–8 December 2024 at three sites (Medicinal Garden, Biodiversity Park, and Biology Education and Research Forest) using casual birdwatching techniques combined with digiscoping to document sighted birds. In total, 26 species representing 25 genera, 19 families, and 7 orders were documented. These included five Near Threatened species, one species listed in CITES Appendix II, four nationally protected species, one Indonesian endemic Prinia familiaris, and two migrants. Passeriformes dominated the records, highlighting their ecological diversity and attractiveness for tourism. An online survey on 44 student respondents showed that 91% of them had at least basic understanding on ecotourism, 95% supported the inclusion of birds as ecotourism attractions, and 50% expressed willingness to pay for avitourism services. Bird aesthetics assessment identified Hemiprocne longipennis (84% score 5) and Eurylaimus ochromalus (80% score 5) as the most attractive species for birdwatching, where the most influencing factors for bird aesthetic were feather coloration, vocalization, behavior, and morphology. These results demonstrate that the vegetated area in Universitas Andalas has potential for avitourism initiatives. Campus-based avitourism can be integrated with biodiversity conservation, empowering environmental education, and generating sustainable tourism opportunities, while engaging communities in conservation-oriented activities that benefit both people and nature.

Abstract

Odonata merupakan kelompok serangga akuatik-terestrial yang banyak dimanfaatkan sebagai indikator kualitas lingkungan perairan karena siklus hidupnya sangat bergantung pada kondisi habitat sungai. Penelitian ini bertujuan untuk mengkaji dinamika komunitas Odonata pada aliran sungai dengan perbedaan karakter vegetasi riparian, yaitu hutan sekunder dan hutan primer, di kawasan Hutan Pendidikan dan Penelitian Biologi (HPPB) Universitas Andalas. Survei dilakukan pada periode Agustus hingga November 2019 menggunakan metode transect point count, dengan tiga kali pengamatan pada sungai hutan sekunder (Sec1, Sec2, dan Sec3) serta satu kali pengamatan pada sungai hutan primer (Prim). Struktur komunitas dianalisis menggunakan indeks keanekaragaman Shannon–Wiener (H′), indeks dominansi Simpson (D), indeks kemerataan (E), serta indeks kelimpahan relatif (RAI). Secara keseluruhan, tercatat 15 spesies Odonata yang berasosiasi dengan habitat sungai, terdiri atas 11 spesies Zygoptera dan 4 spesies Anisoptera. Pada sungai hutan sekunder, nilai H′ masing-masing tercatat sebesar 1,49 pada Sec1, 1,53 pada Sec2, dan 1,40 pada Sec3, dengan nilai D sebesar 0,28, 0,30, dan 0,36 serta nilai E sebesar 0,77, 0,67, dan 0,61. Komunitas Odonata pada habitat sekunder didominasi oleh Heliocypha angusta angusta dengan nilai RAI sebesar 43,90% pada Sec1, 45,45% pada Sec2, dan 54,70% pada Sec3. Pada sungai hutan primer, struktur komunitas menunjukkan nilai H′ sebesar 1,47, nilai D sebesar 0,26, dan nilai E sebesar 0,91, dengan spesies dominan Euphaea modigliani yang memiliki nilai RAI tertinggi sebesar 35,71%. Perbedaan nilai indeks ekologi dan RAI antar habitat menunjukkan pengaruh kuat struktur vegetasi riparian terhadap komposisi, dominansi, dan kestabilan komunitas Odonata, serta menegaskan pentingnya sungai hutan primer bagi konservasi spesies sensitif dan sungai hutan sekunder sebagai habitat pendukung spesies toleran.
