Abstract

The Sulawesi Palm Civet (Macrogalidia musschenbroekii) is the only endemic carnivore on Sulawesi and a key mesopredator within Wallacean forest ecosystems. Despite its conservation significance, empirical information on its population dynamics and habitat associations remains limited. This study analyzes four consecutive years of camera‑trap monitoring (2021–2024) in Bogani Nani Wartabone National Park to evaluate occupancy patterns, environmental drivers, and temporal activity. Using a Bayesian dynamic occupancy framework, we estimated annual occupancy (ψ), detection probability (p), colonization (γ), and local extinction (ε), while examining the influence of elevation, slope, and additional landscape covariates. A consistent sampling effort of 49–50 cameras per year yielded 3,446–4,047 trap nights annually, with low but stable detection rates. Occupancy declined markedly from 0.86 in 2021 to 0.51 in 2024. Elevation and slope emerged as the strongest predictors of occupancy, indicating a preference for mid‑elevation forest habitats. Colonization (0.364–0.654) and extinction probabilities (0.286–0.587) exhibited high interannual variability, suggesting a metapopulation‑like dynamic influenced by habitat fragmentation and environmental instability. Temporal activity analysis revealed predominantly nocturnal and crepuscular behavior, consistent across years. These findings provide the most comprehensive ecological assessment of sulawesi palm civet to date and highlight the species’ sensitivity to habitat degradation. Long‑term monitoring, protection of montane forest corridors, and community‑based conservation programs are recommended to ensure long‑term persistence.

Abstract

Nila is a type of freshwater fish that has high economic value, as a source of animal protein for the community, and is an important commodity in the freshwater fish business. Nila is also one of the main commodities that contributes to the increase in aquaculture production. Nila farming often faces the problem of declining yields due to diseases. One of the diseases that is very detrimental to freshwater fish is diseases caused by fungi. The purpose of this study is to test the toxicity of animal oil in inhibiting the growth of Nila pathogenic fungi. Isolation of pathogenic fungi in fish is carried out by cutting the infected parts (scales, fins, and gills) with a size of about 1x1cm. After pure culture is carried out on each pathogenic fungus, then macroscopic and microscopic identification is carried out. Animal oil (lard oil) is taken in the market that is already available. Animal oil is made in four concentration series, namely 25ppm, 50ppm, 75ppm, and 100ppm and control (0ppm). The toxicity test was carried out in vitro using the toxic bait method, which was carried out by growing Nila pathogenic fungi inoculum on PDA media that had been mixed with animal oil. The results of animal fungicide toxicity testing in 5 treatments (A= control – E= 100 ppm) obtained the diameter of pathogenic fungal colonies (5 pathogenic fungi) ranging from 2.88 cm – 6.82 cm. Animal oil fungicides can affect pathogenic fungi in fish, this can be seen in pathogenic fungi Aspergillus sp. which has a relative resistance of 49% (100 ppm), the category is quite influential with a colony diameter of 3.5 cm and in the pathogenic fungus Mucor sp. With a relative resistance of 56% (100 ppm), the category is quite influential with a colony diameter of 2.88 cm.
