A decade of diversity and forest structure: Post-logging patterns across life stages in an Afrotropical forest

چکیده

• Low-intensity selective logging had negligible effects on basal area. Recently logged (one year since logging) forests more heterogeneous canopy openness. Older (ten years slightly higher sapling diversity. relative liana abundances. Liana removal techniques may be the most effective option for management improvement. Tropical are under threat of increasing pressure from income-generating land uses. Selective is a compromise that allows use while leaving much forest intact across landscape. However, ecological impacts unclear, with evidence positive, negative, and structure We examined impact diversity evergreen tropical in Monts de Cristal region, chain mid-elevation hills northwestern Gabon. For three size classes (seedling, sapling, adult) woody plant species, we tested whether (canopy openness, stem density, area, abundances) were altered been one ten prior, compared to unlogged forest. In general, found no large treatment adult communities, but seedling communities affected. Compared forest, one-year post-logging greater variation openness lower density. Ten-year species evenness, diversity, abundance sapling-sized lianas Our results show key differences between selectively persist understory at least decade after logging. Overall, these contribute an additional data point literature logging, specifically representing very low Central African forests. study highlights value exploring multiple time periods recovery, makes important contribution knowledge managed

Habitat filtering across tree life stages in tropical forest communities.

Tropical tree communities are shaped by local-scale habitat heterogeneity in the form of topographic and edaphic variation, but the life-history stage at which habitat associations develop remains poorly understood. This is due, in part, to the fact that previous studies have not accounted for the widely disparate sample sizes (number of stems) that result when trees are divided into size class...

Species Diversity of Trees and Forest Floor Plants in Oriental beech Forest Types of Shastkalate Educational and Research Forest, Gorgan)

Trees are the most important biological elements of forest ecosystems. The variability of the tree species composition inhabiting in the Oriental beech forest, not only forms different forest types but also has a remarkable impact on the species diversity of forest floor plants, due to the existence of trees in the overstory layer. In this research, forest types of an an Oriental beech were ide...

Patterns of Forest Phylogenetic Community Structure across the United States and Their Possible Forest Health Implications

The analysis of phylogenetic relationships among co-occurring tree species offers insights into the ecological organization of forest communities from an evolutionary perspective and, when employed regionally across thousands of plots, can assist in forest health assessment. Phylogenetic clustering of species, when species are more closely related than expected by chance, suggests a process of ...
