Leaf-level responses to light in two co-occurring Quercus (Quercus ilex and Que...
Vaz, Margarida; Maroco, J.; Ribeiro, Nuno; Gazarini, Luiz Carlos; Pereira, João Santos; Chaves, Maria ManuelaAbstract We studied morphological, biochemical and physiological leaf acclimation to incident Photon- Photosynthetic-Flux-Density (PPFD) in Quercus ilex (holm oak) and Quercus suber (cork oak) at Mediterranean evergreen oak woodlands of southern Portugal. Specific leaf area (SLA) decreased exponentially with increasing PPFD in both species. Q. ilex had lower SLA values than Q. suber. Leaf nitrogen, cellulose an...
Decomposition and nutrient release in halophytes of a Mediterranean salt marsh
Simões, Maria Paula; Calado, Maria da Luz; Madeira, Manuel; Gazarini, Luiz CarlosThis study dealt with the decomposition and nutrient release from the halophytes Atriplex portulacoides, Arthrocnemum macrostachyum, Limoniastrum monopetalum, and Spartina densiflora, the dominant species in the Castro Marim salt marsh, Portugal. Environmental effects on decomposition were also assessed. The study was carried out for one year using the in situ litterbag technique. S. densiflora showed a lower d...
