Representing explicit budburst and senescence processes for evergreen conifers in global models / Peaucelle, Marc (Laboratoire des Sciences du Climat et de l’Environnement) ; Ciais, Philippe (Laboratoire des Sciences du Climat et de l’Environnement) ; Maignant, Fabienne (Laboratoire des Sciences du Climat et de l’Environnement) ; Nicolas, Manuel (France.

Global ecosystem models lack an explicit representation of budburst and senescence for evergreen conifers despite their primordial role in the carbon cycle. In this study we evaluated eight different budburst models, combining forcing, chilling and photoperiod, for their ability to describe spring budburst, and one model of needle senescence for temperate evergreen coniferous forests.

21 p, 1.8 MB Photochemical reflectance index (PRI) for detecting responses of diurnal and seasonal photosynthetic activity to experimental drought and warming in a Mediterranean shrubland / Zhang, Chao (Centre de Recerca Ecològica i Aplicacions Forestals) ; Filella Cubells, Iolanda (Centre de Recerca Ecològica i Aplicacions Forestals) ; Liu, Daijun (Centre de Recerca Ecològica i Aplicacions Forestals) ; Ogaya Inurrigarro, Romà (Centre de Recerca Ecològica i Aplicacions Forestals) ; Llusià Benet, Joan (Centre de Recerca Ecològica i Aplicacions Forestals) ; Asensio Abella, Ma. Dolores (Centre de Recerca Ecològica i Aplicacions Forestals) ; Peñuelas, Josep (Centre de Recerca Ecològica i Aplicacions Forestals)
Climatic warming and drying are having profound impacts on terrestrial carbon cycling by altering plant physiological traits and photosynthetic processes, particularly for species in the semi-arid Mediterranean ecosystems. [...]

17 p, 1.1 MB A remotely sensed pigment index reveals photosynthetic phenology in evergreen conifers / Gamon, John A. (University of Nebraska-Lincoln. Center for Advanced Land Management Information Technologies.) ; Huemmrich, K. Fred (Goddard Space Flight Center) ; Wong, Christopher Y.S. (University of Toronto. Department of Biology) ; Ensminger, Ingo (University of Toronto. Department of Biology) ; Garrity, Steven (Decagon Devices, Inc.) ; Hollinger, David Y. (United States. Forest Service. Northern Research Station) ; Noormets, Asko (North Carolina State University. Departament of Forestry and Environmental Resources) ; Peñuelas, Josep (Centre de Recerca Ecològica i Aplicacions Forestals)
In evergreen conifers, where the foliage amount changes little with season, accurate detection of the underlying “photosynthetic phenology” from satellite remote sensing has been difficult, presenting challenges for global models of ecosystem carbon uptake. [...]

9 p, 296.9 KB Resprouting after experimental fire application and seed germination in Erica vagans / Obeso, José Ramón (Universidad de Oviedo. Departamento de Biología, Organismos y Sistemas) ; Vera, María Luisa (Universidad de Oviedo. Departamento de Biología, Organismos y Sistemas)
Resprouting after experimental fire treatments and the effect of light and heat on seed germination were studied in the evergreen shrub Erica vagans. Experimental fire application consisted of two levels of temperature and two levels of fire duration. [...]
Se estudió la capacidad de rebrote, después de la aplicación experimental de tratamientos de fuego, y la germinación del arbusto perennifolio Erica vagans. El fuego experimental consistió en dos niveles de temperatura y en dos niveles de tiempo de duración y se aplicó a tocones de matorrales previamente cortados. [...]
