dc.description.abstract | Iberian holm oak meadows are savannah-like ecosystems that result from traditional
silvo-pastoral practices. However, such traditional uses are declining, driving changes in the typical
tree—open grassland structure of these systems. Yet, there are no studies integrating the whole
ecosystem—including the arboreal and the herbaceous layer—as drivers of greenhouse gas (GHG:
CO2, CH4 and N2O) dynamics. Here, we aimed at integrating the influence of tree canopies and
interactions among plant functional types (PFT: grasses, forbs, and legumes) of the herbaceous layer
as GHG exchange drivers. For that purpose, we performed chamber-based GHG surveys in plots
dominated by representative canopy types of Iberian holm oak meadows, including Quercus species
and Pinus pinea stands, the last a common tree plantation replacing traditional stands, and unraveled
GHG drivers through a diversity-interaction model approach. Our results show the tree–open
grassland structure, especially drove CO2 and N2O fluxes, with higher emissions under the canopy
than in the open grassland. Emissions under P. pinea canopies are higher than those under Quercus
species. In addition, the inclusion of diversity and compositional terms of the herbaceous layer
improve the explained variability, with legumes enhancing CO2 uptake and N2O emissions. Changes
in the tree cover and tree species composition, in combination with changes in the structure and
composition of the herbaceous layer, will imply deep changes in the GHG exchange of Iberian holm
oak meadows. These results may provide some guidelines to perform better management strategies
of this vast but vulnerable ecosystem. | es |
