“…A MLG of 31 days in our study might be an underestimate, since counting was suspended once we began removing the germinated seeds, due to sprouting of small pieces of the cotyledons that remained in the trays. This cotyledonary reprouting was described by Dalling and Aizprúa (1997). These four species are dispersed in the rainy season, and their dormant period is not long enough to delay germination until the next rainy season.…”

“…Firstly, initial plot conditions may have favored early establishment of G. superba post‐disturbance (Estrada‐Villegas et al., 2019 ; Hooper et al., 2004 ), and agouti‐mediated feedback loops of seed dispersal in areas of high G. superba abundance (Forget, 1992 ) may have maintained this dominance. Secondly, G. superba seeds are resistant to damage and insect infestation (Dalling & Aizprua, 1997 ; Dalling & Harms, 1999 ), and G. superba can resprout following damage as an adult (Putz & Brokaw, 1989 ). Resprouting is a key trait linked to monodominance in Amazonia (ter Steege et al., 2019 ), and thus these traits likely maintain high G. superba abundance.…”

Determining how fully tropical forests regenerating on abandoned land recover characteristics of old‐growth forests is increasingly important for understanding their role in conserving rare species and maintaining ecosystem services. Despite this, our understanding of forest structure and community composition recovery throughout succession is incomplete, as many tropical chronosequences do not extend beyond the first 50 years of succession. Here, we examined trajectories of forest recovery across eight 1‐hectare plots in middle and later stages of forest succession (40–120 years) and five 1‐hectare old‐growth plots, in the Barro Colorado Nature Monument (BCNM), Panama. We first verified that forest age had a greater effect than edaphic or topographic variation on forest structure, diversity and composition and then corroborated results from smaller plots censused 20 years previously. Tree species diversity (but not species richness) and forest structure had fully recovered to old‐growth levels by 40 and 90 years, respectively. However, rare species were missing, and old‐growth specialists were in low abundance, in the mid‐ and late secondary forest plots, leading to incomplete recovery of species composition even by 120 years into succession. We also found evidence that dominance early in succession by a long‐lived pioneer led to altered forest structure and delayed recovery of species diversity and composition well past a century after land abandonment. Our results illustrate the critical importance of old‐growth and old secondary forests for biodiversity conservation, given that recovery of community composition may take several centuries, particularly when a long‐lived pioneer dominates in early succession.Abstract in Spanish is available with online material.
