Landscape structure shapes the diversity of tree seedlings at multiple spatial scales in a fragmented tropical rainforest.

The maintenance of seedling diversity of animal-dispersed tree species is fundamental for the structure and function of forest patches in fragmented tropical rainforests. Nonetheless, the effects of landscape structure at different spatial scales on α- and β-diversity of tree seedling communities ar...
