Abstract

Mosses growing on the surface of the Borobudur Temple will affect the aesthetic value of the temple. Interaction between moss and actinomycetes may trigger the growth of moss that can cause an increase in biodeterioration of stone. The purpose of this study was to isolate and identify the actinomycetes associated with moss on the surface of decayed stone of Borobudur Temple as well to assess their ability for phosphate solubilizing. Actinomycetes were isolated using serial dilution method and were identified based on 16S rRNA gene sequences. A total of 37 actinomycetes were isolated from three sampling sites. The isolates found belong to five genera (Gordonia, Microbacterium, Micromonospora, Nocardia, and Streptomyces) and distributed among four families (Microbacteriaceae, Micromonosporaceae, Nocardiaceae, and Streptomycetaceae). Isolates of actinomycetes composed of 19 Streptomyces Group and 18 Rare Actinomycetes Group. Nineteen isolates (51.35%) were identified as genus Streptomyces. Seventeen isolates (45.94%) showed abilities to release soluble phosphate and most of the isolates belong to the genus Streptomyces. The isolates have been collected will be deposited to Indonesian Culture Collection (InaCC) to enrich the collection of actinomycetes from ancient stone in Indonesia and will be used as a source of reference material research, taxonomic, or as source for further study.

Abstract

Environmental and genetic variables can exert an influence on alterations in morphological traits. Within fish species inhabiting diverse aquatic settings, there can be observed variations in morphological traits. Genetically, variations in fish morphological characteristics can occur through mating and gene flow. To date, there has been a lack of research conducted on the variability in morphological traits and genetic relationships between Lutjanus timoriensis, L. malabaricus, and L. erythropterus. Thus, the current research aimed to identify variations in the morphological characteristics as well as in the intra- and inter-specific relationships between three red snapper species from the genus Lutjanus.  Cytochrome oxidase I (COI) gene was used to study the molecular relationship among species of red snapper. The results showed that L. timoriensis had high intraspecific morphological variation in young individuals. Morphologically, L. timoriensis, L. malabaricus, and L. erythropterus are very similar. Unlike L. malabaricus and L. erythropterus, young and adult L. timoriensis have black patches in the pectoral fin axils. The adult L. erythropterus has a comparatively small mouth, no hump on its head, and no black saddle at the base of its tail. Meanwhile, L. malabaricus has a comparatively large mouth, a head with a hump, and a black saddle at the base of its tail. In terms of body size, L. erythropterus is larger than L. timoriensis and L. malabaricus. Based on NCBI and Bold System data, molecular analyses determined that the observed fish were L. timoriensis, L. malabaricus, L. erythropterus with a similarity of between 99.85 and 100%. The phylogenetic tree construction demonstrated that L. malabaricus, L. timoriensis and L. erythropterus were closely related.

Abstract

The Lutjanidae family has a wide range of varieties, posing challenges in their morphological identification. Molecular identification is crucial for augmenting the current morphological data as a comprehensive database for documenting the presence of economically significant fish species in Nabire water. This article provides a comprehensive analysis of the morphological and genetic characteristics of red snapper species, as well as assessment of the evolutionary connections among snapper fish found in the water. This study aims to analyze the morphological and genetic characteristics of red snapper species and assess the evolutionary relationships among red snapper found in the sea waters. The DNA extraction procedure was conducted according to the instructions provided by the Geneaid gSYNC DNA extraction kit. The molecular marker used is the DNA barcode of the cytochrome oxidase subunit I (CO1) gene. A total of 29 individuals were identified, representing 8 species, namely Lutjanus timoriensis, Lutjanus gibbus, Lutjanus bohar, Lutjanus papuensis, Pinjalo lewisi, Etelis coruscans, Pristipomoides multidens, and Aphareus rutilans. The molecular analysis indicated that there was a fragment length of 620 base pairs (bp). P. multidens and L.  gibbus had the greatest genetic distance (0.22), whilst the species L. bohar and L. gibbus had the smallest genetic distance (0.11). The phylogenetic tree reconstruction yielded 8 monophyletic clades. Based on morphological and genetic analysis, eight species of the Lutjanidae family were identified in Nabire waters. Research is needed on biological parameters such as size when first caught, optimum length of capture and size when first gonad mature.
