Assembly patterns of tree seedling communities in a human‐dominated Tropical landscape
Authors:Tatiane G. C. Menezes  Felipe P. L. Melo
Abstract:Understanding how different components of species diversity of regenerating areas respond to both time of abandonment and landscape metrics may offer crucial information for both theoretical and practical purposes. Using 15 regeneration areas (from 4 to 30 years) and nine areas of mature forest, we assessed how tree seedling assemblage responds to time of abandonment and forest cover in terms of species diversity and taxonomic composition. We found that species diversity of seedlings responded positively to time of abandonment, but was not influence by forest cover. Diversity of rare and common species (0D and 1D, respectively) but not dominant species (2D) increased with time of abandonment, reaching reference values very quickly (ca. 20 years). However, species composition seemed to respond to both ageing of forest stand and landscape structure represented by forest cover. Our findings reinforce that in human‐dominated landscapes, local processes related to recovery with time should be more important for plant community assembly than landscape structure, leading to a number of possibilities for multiple successional pathways. Abstract in Portuguese is available with online material.
