Abstract: To achieve the ambitious goals of the UN Decade on Ecosystem Restoration, restoration frameworks should embrace the ersity of ecosystems found on Earth, including open‐canopy ecosystems, which have been largely overlooked. Considering the paucity of scientific foundations promoting restoration science, policy, and practice for open tropical ecosystems, we provide overarching guidelines to restore the c o rupestre , a Neotropical, open mega erse grassland that has been increasingly threatened by multiple human activities, especially mining. Restoration techniques for tropical grasslands are still at its infancy, and attempts to restore c o rupestre have had, so far, low to moderate success, highlighting the need for a tailored restoration framework. In a scenario of increasing degradation and scarcity of on‐site restoration experiments, we propose 10 principles to improve our ability to plan, implement, and monitor restoration in c o rupestre : (1) include socioeconomic dimensions, (2) implement active restoration, (3) keep low soil fertility, (4) restore disturbance regimes, (5) address genetic structure and adaptation potential, (6) restore geographically restricted and specialized ecological interactions, (7) incorporate functional approaches, (8) use seed‐based restoration strategies to enhance bio ersity, (9) translocation is inevitable, and (10) long‐term monitoring is mandatory. Our principles represent the best available evidence to support better science and practice for the restoration of c o rupestre and, to some extent, can be useful for other mega erse, fire‐prone, and nutrient‐poor ecosystems.

Abstract: The extent of specialization/generalization continuum in fruit-frugivore interactions at the in idual level remains poorly explored. Here, we investigated the interactions between the Neotropical treelet Miconia irwinii (Melastomataceae) and its avian seed dispersers in Brazilian c o rupestre. We built an in idual-based network to derive plant degree of interaction specialization regarding disperser species. Then, we explored how intraspecific variation in interaction niche breadth relates to fruit availability on in idual plants in varying densities of fruiting conspecific neighbors, and how these factors affect the quantity of viable seeds dispersed. We predicted broader interaction niche breadths for in iduals with larger fruit crops in denser fruiting neighborhoods. The downscaled network included nine bird species and 15 plants, which varied nearly five-fold in their degree of interaction specialization. We found positive effects of crop size on visitation and fruit removal rates, but not on degree of interaction specialization. Conversely, we found that an increase in the density of conspecific fruiting neighbors both increased visitation rate and reduced plant degree of interaction specialization. We suggest that tracking fruit-rich patches by avian frugivore species is the main driver of density-dependent intraspecific variation in plants' interaction niche breadth. Our study shed some light on the overlooked fitness consequences of intraspecific variation in interaction niches by showing that in iduals along the specialization/generalization continuum may have their seed dispersed with similar effectiveness. Our study exemplifies how in idual-based networks linking plants to frugivore species that differ in their seed dispersal effectiveness can advance our understanding of intraspecific variation in the outcomes of fruit-frugivore interactions.
