“…These gallery forests form a natural ecotone with grasslands or savannas, thus forming natural forest edges (Silva et al, 2008) differing from the core of the gallery forests (i.e., interiors) in terms of structure, composition, and dynamics (Van den Berg & Oliveira-Filho, 1999;Bragion et al, 2018), but yet can harbor a great diversity of tree species (de Oliveira Coelho et al, 2016). By now, we know that AGB decreases toward the edges of gallery forests (Nunes et al, 2018;Silva et al, 2019;Deziderio Santana et al, 2021), in a way very similar to anthropogenic forest fragments (Laurance et al, 2002), even though the alpha diversity of gallery forest edges and interiors seems similar (Van den Berg & Oliveira-Filho, 1999;Van den Berg & Santos, 2003). This natural configuration offers a great opportunity to understand the separate contribution of changes in species richness, species composition, and context-dependent responses to explain AGB variation across the edge-interior continuum.…”
