The effect of tree decline over soil water content largely controls soil respir...
Rodríguez, Alexandra; Durán, Jorge; Curiel Yuste, Jorge; Valladares, Fernando; Rey, AnaAs drought-induced tree defoliation and mortality (i.e. tree decline) in the Mediterranean with ongoing climate change, it is of paramount importance to understand how, why, and when tree decline affects soil respiration (Rs). We carried out a novel study exploring the interacting effects of climatic variability (i.e. season and year) and tree decline on soil water content (SWC), soil temperature (Tsoil), and R...
The exploitative segregation of plant roots
Cabal, Ciro; Martínez-García, Ricardo [UNESP]; De Castro Aguilar, Aurora; Valladares, Fernando; Pacala, Stephen W.Made available in DSpace on 2021-06-25T10:46:04Z (GMT). No. of bitstreams: 0 Previous issue date: 2020-12-04; Plant roots determine carbon uptake, survivorship, and agricultural yield and represent a large proportion of the world's vegetation carbon pool. Study of belowground competition, unlike aboveground shoot competition, is hampered by our inability to observe roots. We developed a consumer-resource model ...
Future paths for the ‘exploitative segregation of plant roots’ model
Cabal, Ciro; Martinez-Garcia, Ricardo [UNESP]; de Castro, Aurora; Valladares, Fernando; Pacala, Stephen W.Made available in DSpace on 2021-06-25T10:54:14Z (GMT). No. of bitstreams: 0 Previous issue date: 2021-01-01; The exploitative segregation of plant roots (ESPR) is a theory that uses a game-theoretical model to predict plant root foraging behavior in space. The original model returns the optimal root distribution assuming exploitative competition between a pair of identical plants in soils with homogeneous reso...

Steidinger, Brian S.; Crowther, Thomas Ward; Liang, Jingjing; van Nuland, Michael E.; Werner, Gijsbert; Reich, Peter B.; Nabuurs, Gert JanIn this Letter, the middle initial of author G. J. Nabuurs was omitted, and he should have been associated with an additional affiliation: ‘Forest Ecology and Forest Management Group, Wageningen University and Research, Wageningen, The Netherlands’ (now added as affiliation 182). In addition, the following two statements have been added to the Supplementary Acknowledgements. (1): ‘We would particularly like to ...

Functional antagonism between nitrogen-fixing leguminous trees and calcicole-dr...
Meira-Neto, João Augusto Alves; Tolentino, Gláucia Soares; Silva, Maria Carolina Nunes Alves da; Neri, Andreza Viana; Gastauer, MarkusThe Cerrado is the largest savanna of South America and its physiognomy varies from savanna to woodlands. There are two main types of woodlands in the Cerrado: dystrophic woodlands, dominated by N-fixing leguminous trees (LEG), and mesotrophic woodlands dominated by non-leguminous drought-tolerant trees (DRY), which are calcicoles and sensitive to Al3+. The working hypothesis is that LEG and DRY are functional ...
Phylogenetic community structure reveals differences in plant community assembl...
Gastauer, Markus; Saporetti-Junior, Amílcar W.; Valladares, Fernando; Meira-Neto, João A. A.Mussununga, an oligotrophic sandy savanna ecosystem, comprises distinct physiognomies along fire, water and nutrient availability gradients. Grasslands and woodlands are constrained at the opposite poles of these gradients, with grasslands occurring in areas with poorer soils and higher levels of both water-stress and fire intensity. According to the stress-dominance hypothesis, one might expect the importance ...
Positive biodiversity-productivity relationship predominant in global forests
Liang, Jingjing; Crowther, Thomas W; Picard, Nicolas; Wiser, Susan; Zhou, Mo; Alberti, Giorgio; Schulze, Ernst-Detlef; McGuire, A David; Bozzato, FabioThe biodiversity-productivity relationship (BPR) is foundational to our understanding of the global extinction crisis and its impacts on ecosystem functioning. Understanding BPR is critical for the accurate valuation and effective conservation of biodiversity. Using ground-sourced data from 777,126 permanent plots, spanning 44 countries and most terrestrial biomes, we reveal a globally consistent positive conca...
