Bengkalis Island is one of the islands where 85% of the landscape consists of peatland, originally covered by native peat swamp forests. Over the past five decades, deforestation in this area has led to the near-total loss of this native vegetation. This study aimed to analyze the remaining fragments of peat swamp forest and characterize their ecological features. Field data were collected in t…
Staphylococcus is one of the microorganisms that often cause skin infections. The continuous use of antibiotics can lead to the possibility of resistance. Plant extracts such as Mangifera sumatrana and Ruellia tuberosa have the potential to inhibit the growth of pathogenic bacteria. Both plants contain bioactive compounds as antibacterial agents. The aim of this study is to determine the antiba…
The diversity of ants is influenced by habitat variations, as ants are highly sensitive to environmental changes. Ecological factors such as vegetation and microclimate can affect their distribution and abundance. This study aims to examine the composition, diversity, and evenness of ant species across different habitats within the University of Riau area. The research on ant species diversity …
Fiddler crabs (Uca spp.) have an important role in maintaining the balance of the food chain and nitrogen cycle in mangrove ecosystems.
