Structural, physiognomic and above-ground biomass variation in savanna-forest t...
Veenendaal, Elmar M.; Torello-Raventos, Mireia; Feldpausch, Ted R.; null, Tomas; Gerard, France F.; Schrodt, Franziska; Saiz, GustavoThrough interpretations of remote-sensing data and/or theoretical propositions, the idea that forest and savanna represent "alternative stable states" is gaining increasing acceptance. Filling an observational gap, we present detailed stratified floristic and structural analyses for forest and savanna stands located mostly within zones of transition (where both vegetation types occur in close proximity) in Afri...
Foliar trait contrasts between African forest and savanna trees: Genetic versus...
Schrodt, Franziska; null, Tomas; Feldpausch, Ted R.; Saiz, Gustavo; Quesada, Carlos Alberto; Schwarz, Michael; Ishida, Francoise Yoko; Compaoré, HalidouVariations in leaf mass per unit area (Ma) and foliar concentrations of N, P, C, K, Mg and Ca were determined for 365 trees growing in 23 plots along a West African precipitation gradient ranging from 0.29 to 1.62m a-1. Contrary to previous studies, no marked increase in Ma with declining precipitation was observed, but savanna tree foliar [N] tended to be higher at the drier sites (mass basis). Generally, Ma w...
The influence of C3 and C4 vegetation on soil organic matter dynamics in contra...
Saiz, Gustavo; Bird, Michael I.; Wurster, Christopher M.; Quesada, Carlos Alberto; Ascough, Philippa L.; null, Tomas; Schrodt, FranziskaVariations in the carbon isotopic composition of soil organic matter (SOM) in bulk and fractionated samples were used to assess the influence of C3 and C4 vegetation on SOM dynamics in semi-natural tropical ecosystems sampled along a precipitation gradient in West Africa. Differential patterns in SOM dynamics in C3/C4 mixed ecosystems occurred at various spatial scales. Relative changes in C / N ratios between ...
