Popis: The ubiquity of anthropogenic pressures in tropical regions is the primary threat to biodiversity, and one of the most significant challenges humanity is currently facing (Lewis et al., 2015). Hope is set on regrowing secondary forests, which may serve as habitat refugia for many species and play a central role in ecosystem functioning (Hethcoat et al., 2019). Secondary forests currently account for over half of the world's tropical forests, and their distribution is expanding as they gradually replace old-growth stands that have been clear-cut for productive use, but subsequently abandoned (Chazdon et al., 2016). Nowadays, however, the capacity of these regrowing stands to return to their original state is uncertain (Arroyo-Rodriguez et al., 2017) as they occur mostly as isolated, small patches embedded in matrices dominated by agricultural and pasture lands (Barlow et al., 2016). To further understand the potential role of successional forests as a buffer against biodiversity loss, we need to move the discussion from local to landscape scales and embrace the manifold forces driving succession (Arroyo-Rodriguez et al., 2017; van Breugel et al., 2019).
