Abstract

The Imbo Putui Customary Forest is an ecosystem that plays an important ecological role as a provider of environmental services and habitat for tropical biodiversity. This study analyzes the diversity of understory plants in the Imbo Putui Customary Forest using a descriptive quantitative research design. Data collection was carried out using a 100 × 20 m main plot combined with 2 × 2 m subplots as sampling units for understory vegetation. The results of this study show that there are 29 plant species belonging to 18 families, originating from 4 habits: herbaceous, shrub, grass, and shrub, and three families were found to be abundant, namely Poaceae, Arecaceae, and Asteraceae. The results showed that the understory plant community consisted of various growth forms, with herbaceous plants showing the highest level of diversity, while shrubs showed the lowest level of diversity. Overall, the level of diversity indicates that the forest ecosystem is in relatively good ecological condition. These findings confirm the ecological stability of the Imbo Putui Customary Forest and emphasize the importance of sustainable conservation and management efforts to maintain ecosystem balance and provide benefits to indigenous communities.

Abstract

Mangrove species exhibit variations in leaf functional traits that reflect differences in resource-use strategies; however, information on the coordination of these traits during the seedling stage remains limited. This study aimed to evaluate leaf functional trait variation among four mangrove species (Avicennia alba, Bruguiera gymnorrhiza, Bruguiera parviflora, and Rhizophora apiculata) by analyzing leaf economic traits, leaf morphological traits, and their interrelationships. A total of 120 seedlings grown under relatively uniform nursery conditions were evaluated. The measured traits included Specific Leaf Area (SLA), Leaf Dry Matter Content (LDMC), Aspect Ratio (AR), and Shrinkage Index (SI). Data were analyzed using descriptive statistics, one-way analysis of variance (ANOVA) followed by Duncan's Multiple Range Test (DMRT), and Principal Component Analysis (PCA). The results showed that all measured traits differed significantly among species (P < 0.05), with effect sizes ranging from moderate to very large. PCA revealed that the first two principal components explained 73.75% of the total variation in leaf traits, indicating that interspecific variation was driven by the coordination of multiple leaf traits rather than by a single trait. These findings demonstrate that a multivariate approach provides a more comprehensive understanding of leaf functional trait variation among mangrove seedlings.
