14 p, 3.3 MB Calibrating the severity of forest defoliation by pine processionary moth with landsat and UAV imagery / Otsu, Kaori (Centre de Recerca Ecològica i Aplicacions Forestals) ; Pla, Magda (InForest JRU) ; Vayreda Duran, Jordi (Centre de Recerca Ecològica i Aplicacions Forestals) ; Brotons Alabau, Lluís (Centre de Recerca Ecològica i Aplicacions Forestals)
The pine processionary moth (Thaumetopoea pityocampa Dennis and Schiff. ), one of the major defoliating insects in Mediterranean forests, has become an increasing threat to the forest health of the region over the past two decades. [...]

13 p, 7.2 MB Assessing pine processionary moth defoliation using unmanned aerial systems / Cardil, Adrián (Centre de Recerca Ecològica i Aplicacions Forestals) ; Vepakomma, Udayalakshmi (FPInnovations. Canada) ; Brotons Alabau, Lluís (Centre de Recerca Ecològica i Aplicacions Forestals)
Pine processionary moth (PPM) is one of the most destructive insect defoliators in the Mediterranean for many conifers, causing losses of growth, vitality and eventually the death of trees during outbreaks. [...]

15 p, 2.1 MB Species climatic niche explains drought-induced die-off in a Mediterranean woody community / Sapes, Gerard (Centre de Recerca Ecològica i Aplicacions Forestals) ; Serra Díaz, Josep M. (Harvard Forest (Research facility)) ; Lloret Maya, Francisco (Universitat Autònoma de Barcelona. Departament de Biologia Animal, de Biologia Vegetal i d'Ecologia)
During the last decades, plant die-off has been reported worldwide as a result of increased frequency and intensity of extreme drought events. From a niche perspective, a species performance should decrease as the climatic conditions defining a drought event differ from those characterizing the species climatic niche (the average conditions experienced by the species). [...]

41 p, 1.6 MB Sequence of plant responses to droughts of different timescales : lessons from holm oak (Quercus ilex) forests / Barbeta i Margarit, Adrià (Centre de Recerca Ecològica i Aplicacions Forestals) ; Peñuelas, Josep (Universitat Autònoma de Barcelona. Departament de Biologia Animal, de Biologia Vegetal i d'Ecologia)
The functional traits of plants in regions of the world with a Mediterranean climate have been shaped to tolerate periods of water deficit. These species are adapted to summer droughts but may not be able to cope with future increases in drought intensity, duration, and/or frequency. [...]

22 p, 260.1 KB Visible ozone-like injury, defoliation, and mortality in two Pinus uncinata stands in the Catalan Pyrenees (NE Spain) / Díaz de Quijano Barbero, Maria (Centre de Recerca Ecològica i Aplicacions Forestals) ; Kefauver, Shawn (Centre de Recerca Ecològica i Aplicacions Forestals) ; Ogaya Inurrigarro, Romà (Universitat Autònoma de Barcelona. Departament de Biologia Animal, de Biologia Vegetal i d'Ecologia) ; Vollenweider, Pierre (Swiss Federal Institute for Forest, Snow and Landscape Research WSL) ; Ribas Artola, Àngela (Universitat Autònoma de Barcelona. Departament de Biologia Animal, de Biologia Vegetal i d'Ecologia) ; Peñuelas, Josep (Universitat Autònoma de Barcelona. Departament de Biologia Animal, de Biologia Vegetal i d'Ecologia)
Ozone concentrations in the Pyrenees have exceeded the thresholds for forest protection since 1994. We surveyed the severity of visible O₃ injuries, crown defoliation, and tree mortality of Pinus uncinata, the dominant species in subalpine forests in this mountain range, along two altitudinal and O₃ gradients in the central Catalan Pyrenees and analysed their relationships with the local environmental conditions. [...]

10 p, 956.2 KB A global change-induced biome shift in the Montseny mountains (NE Spain) / Peñuelas, Josep (Universitat Autònoma de Barcelona. Departament de Biologia Animal, de Biologia Vegetal i d'Ecologia) ; Boada, Martí 1949- (Universitat Autònoma de Barcelona. Departament de Geografia)
Shifts in plant species and biome distribution in response to warming have been described in past climate changes. However, reported evidence of such shifts under current climate change is still scarce. [...]
