“…However, little attention has been paid to gap regeneration on spatial scales, especially along an elevation gradient [4]. As an important geographical factor, elevation Forests 2023, 14, 2099 2 of 17 is a strong driver of spatial variation in environmental factors (e.g., temperature, precipitation, and soil properties) that affect species distribution, species regeneration, and coexistence [10,11]. For example, a study on canopy gaps in Atlantic Rainforests suggested that a low altitude (at approximately 350 m a.s.l.)…”

Forest gaps play an important role in species regeneration and forest succession. Gap size has a primary influence on tree species coexistence and community assembly along an elevation gradient. In this study, we evaluated the regeneration and coexistence of Abies faxoniana, Betula utilis, and Acer maximowiczii at different life history stages in varied gap sizes along an elevation gradient (between 3000 and 3500 m a.s.l). We found that gap size can positively enlarge the effects of elevation on the regeneration density of the three species. In the process of regeneration from seedling to sapling, Abies had stronger regeneration capability, with regeneration niche breadths of more than 0.6 in different gap sizes. A factor analysis of mixed data indicated that regeneration density, soil nutrient contents, and air humidity were mainly related to gap size, but habitat temperature was largely determined by elevation. The connection between the species regeneration density and habitat conditions was due to differences in their regeneration niches, reflecting the selective preemption of environmental resources of different species in different life stages. Microhabitat heterogeneity, controlled by the characteristics of forest gaps along an elevation, affected the regeneration niche differences of the tree species, which contributed to the species coexistence and community assembly processes.
