Article Synopsis
- The study investigates how arbuscular mycorrhizal (AM) and ectomycorrhizal (EcM) associations influence tree diversity across different latitudes, using data from over 2.8 million trees.
- AM trees were found to significantly contribute to reducing total tree diversity and turnover while enhancing nestedness at higher latitudes, contrasting with EcM trees that show less influence on compositional differences.
- Environmental factors, especially temperature and precipitation, were more closely related to the beta-diversity patterns of AM trees, emphasizing the role of AM associations in maintaining global forest biodiversity.
While invasive species may be visible indicators of plant community degradation, they may not constitute the only, or even the primary, limitation to stand regeneration. We used seed-augmentation and grass-removal experiments under different canopy conditions to assess the relative importance of dispersal limitation, resource availability, and competition on seedling establishment in the understory shrubs Sophora chrysophilla, Dodonea viscosa, and Pipturus albidus in a montane mesic forest in Hawaii. The study location was an Acacia koa-Metrosideros polymorpha forest at 1000-1500 m elevation on the leeward side of Hawaii Island; it is a closed-canopy forest historically subject to logging and grazing by cattle and sheep and currently dominated by the exotic grass, Ehrharta stipoides, in the herb layer.
