Indonesian Journal of Ecology and Conservation is a journal published in 2024 by the Center for Ecology, Conservation, and Ethnobiology Studies at the Universitas Sulawesi Barat, Indonesia. The establishment of this journal is driven by the importance of recognizing the diversity of flora and fauna in Indonesia, particularly on the island of Sulawesi. The geographical uniqueness of this island, separated from the continents of Asia and Australia, has allowed for the evolution of different species and is a primary cause of its biodiversity richness. This aspect is certainly attractive for research by various groups, and the Indonesian Journal of Ecology and Conservation serves as an appropriate platform for accessing and publishing research findings in the fields of ecology, conservation, molecular, systematic, and evolutionary studies

Abstract

Patchouli (Pogostemon cablin Benth.) is a significant tropical bioresource known for its essential oil, which possesses high ethnobiological and economic value but cannot yet be synthetically produced. This study aims to establish an in vitro conservation framework and evaluate the preservation of secondary metabolites (volatile oil) within callus cultures. Leaf explants were cultured on Murashige and Skoog (MS) media supplemented with various combinations of 2,4-D and BAP: 1 ppm BAP (W1), 1 ppm BAP + 1 ppm 2,4-D (W2), 1 ppm BAP + 2 ppm 2,4-D (W3), 2 ppm BAP + 1 ppm 2,4-D (W4), and 2 ppm BAP + 2 ppm 2,4-D (W5). The results indicated that W1 (1 ppm BAP without 2,4-D) was the most effective treatment for sustainable biomass production, achieving a 75% growth rate, the fastest induction time (6 days), and the highest fresh weight (0.1364 g). Thin Layer Chromatography (TLC) profiling confirmed that the in vitro callus successfully preserved volatile oil components identical to the mother plant, as evidenced by purple spots at Rf values of 0.75 and 0.95. Although alkaloids and flavonoids were not detected due to the cellular dedifferentiation phase, the consistent presence of volatile oils demonstrates the potential of in vitro systems for the conservation and sustainable management of tropical aromatic plant metabolites.

Abstract

Sulawesi Island is a key area of the Wallacea region, known for its high level of plant endemism, including the genus Pogostemon. A comprehensive taxonomic study is essential to document the biodiversity and provide accurate identification for tropical resource management. This study aims to examine the taxonomic characters of Pogostemon spp. collected from Sulawesi and deposited at Herbarium Bogoriense (BO). Using a descriptive method based on morphological characteristics of 13 collection numbers, the study analyzed vegetative and reproductive structures. The results identified two distinct species: Pogostemon cablin (Blanco) Benth. and Pogostemon auricularius Hassk. These species are clearly distinguished by the shape of the leaf blade, calyx structure, and the type of indumentum present on the stem, leaf, and flower surfaces. This taxonomic study contributes to the baseline data of Lamiaceae in Sulawesi, supporting further research in plant ecology and conservation of tropical flora

Abstract

Bats (Chiroptera) play important ecological roles in tropical island ecosystems, yet information on their community structure in small island systems remains limited. This study aims to analyze species composition, abundance, and habitat associations of bat communities in Wakatobi. Field surveys were conducted in September 2023 across three islands (Wangi-wangi, Kaledupa, and Tomia) using a combination of mist nets and roost observations. A total of 10 sampling points were established, consisting of 5 cave sites, 3 mangrove sites, and 2 terrestrial vegetation sites, with one mist net deployed at each point. Data were analyzed using diversity indices (Shannon-Wiener and Simpson), descriptive abundance analysis, and multivariate approaches including Principal Component Analysis (PCA) and PERMANOVA. A total of 1,604 individuals representing five species from three genera (Pteropus, Rousettus, and Hipposideros) were recorded. The community was strongly dominated by frugivorous bats, particularly Pteropus pumilus (84.47%), which was primarily associated with mangrove and terrestrial vegetation habitats. In contrast, cave habitats were dominated by insectivorous species such as Hipposideros galeritus. Diversity indices indicated low species diversity but high dominance, especially in mangrove habitats. PCA results revealed a clear ecological gradient separating vegetation and cave habitats, with the first two components explaining 100% of total variation (Dim1 = 71.7%; Dim2 = 28.3%). These findings demonstrate strong habitat-driven community structuring and niche differentiation among bat species. This study represents the first assessment of bat community structure in Wakatobi using a PCA-based multivariate approach, providing new insights into habitat–species relationships in small island ecosystems. The results highlight the importance of conserving mangrove and cave habitats as complementary systems supporting bat diversity and ecosystem functions.

Abstract

Noni (Morinda citrifolia L.) is a pioneer species in tropical ecosystem succession, known for its ability to persist under various environmental conditions. This study aims to analyze the internal leaf architecture of Noni to elucidate its ecophysiological adaptation strategies. Leaf samples were collected from multiple individuals and examined using transparent nail polish impression techniques and microscopic observations. The analysis focused on epidermal characteristics, stomatal density, and mesophyll organization. Quantitative results showed that stomata were exclusively distributed on the abaxial surface, confirming a hypostomatic pattern, with a mean stomatal density of 245 ± 32 stomata/mm². The stomata were identified as anomocytic type. Epidermal observations revealed the presence of non-glandular trichomes, suggesting a primarily physical protective function. Anatomically, the mesophyll exhibited a dorsiventral structure, with a two-layered palisade tissue contributing approximately 45.8% of total mesophyll thickness, indicating adaptation to high light intensity. The spongy tissue with large ellular spaces facilitates efficient gas exchange. Overall, these findings indicate that the leaf anatomical traits of M. citrifolia reflect potential structural adaptations to environmental conditions such as high irradiance and water limitation. However, further comparative and physiological studies are required to confirm the ecological significance of these traits in enhancing plant resilience across diverse habitats

Abstract

The sustainability of livestock ecosystems increasingly depends on improving feed conversion efficiency and reducing reliance on synthetic chemical additives. Probiotics offer a biological alternative to enhance poultry productivity while maintaining ecological balance. This study aims to evaluate the enhancement of egg protein content in laying hens (Gallus sp.) through the integration of liquid probiotics into sustainable poultry systems. The research followed a Completely Randomized Design (CRD) with three treatments: control (M0), liquid probiotic culture (M1), and commercial probiotic (M2). Egg protein content was analyzed using the Kjeldahl method, involving digestion, distillation, and titration to determine total nitrogen levels, which were converted into crude protein percentages. The findings indicate that while liquid probiotic integration showed a positive trend in enhancing egg protein levels, the statistical analysis revealed no significant difference (P>0.05) among treatments. The liquid probiotic culture (M1) yielded the highest mean protein content at 11.26 ± 1.361 mg/g, compared to the control group (10.5 ± 1.371 mg/g). This numerical improvement suggests that probiotics support gut microflora health, potentially aiding nitrogen metabolism efficiency. Although not statistically significant in this trial, the implementation of probiotics in sustainable livestock systems supports ecosystem conservation by providing a chemical-free alternative for poultry management and promoting long-term biological resilience
