10 p, 459.5 KB Trade-offs between vegetative growth and acorn production in Quercus lobata during a mast year : the relevance of crop size and hierarchical level within the canopy / Sanchez-Humanes, Belén (Centre de Recerca Ecològica i d'Aplicacions Forestals) ; Sork, Victoria L. (University of California. Department of Ecology and Evolutionary Biology) ; Espelta Morral, Josep Maria (Centre de Recerca Ecològica i d'Aplicacions Forestals)
The concept of trade-offs between reproduction and other fitness traits is a fundamental principle of life history theory. For many plant species, the cost of sexual reproduction affects vegetative growth in years of high seed production through the allocation of resources to reproduction at different hierarchical levels of canopy organization. [...]

13 p, 348.8 KB The interplay among acorn abundance and rodent behavior drives the spatial pattern of seedling recruitment in mature Mediterranean oak forests / Sunyer, Pau (Centre de Recerca Ecològica i d'Aplicacions Forestals) ; Boixadera Planas, Ester (Universitat Autònoma de Barcelona. Servei d'Estadística Aplicada) ; Muñoz, Alberto (Centre de Recerca Ecològica i d'Aplicacions Forestals) ; Bonal, Raul (Centre de Recerca Ecològica i d'Aplicacions Forestals) ; Espelta Morral, Josep Maria (Centre de Recerca Ecològica i d'Aplicacions Forestals)
The patterns of seedling recruitment in animal-dispersed plants result from the interactions among environmental and behavioral variables. However, we know little on the contribution and combined effect of both kinds of variables. [...]

41 p, 1.2 MB Tropical insect diversity : evidence of greater host specialization in seed-feeding weevils / Peguero, Guille (Centre de Recerca Ecològica i d'Aplicacions Forestals) ; Bonal, Raul (Instituto de Investigación de la Dehesa) ; Sol, Daniel (Centre de Recerca Ecològica i d'Aplicacions Forestals) ; Muñoz, Alberto (Centre de Recerca Ecològica i d'Aplicacions Forestals) ; Sork, Victoria L. (University of California. Department of Ecology and Evolutionary Biology) ; Espelta Morral, Josep Maria (Centre de Recerca Ecològica i d'Aplicacions Forestals)
Host specialization has long been hypothesized to explain the extraordinary diversity of phytophagous insects in the tropics. However, addressing this hypothesis has proved challenging because of the risk of over-looking rare interactions, and hence biasing specialization estimations, and the difficulties to separate the diversity component attributable to insect specialization from that related to host diversity.

13 p, 3.6 MB Contrasting effects of fire severity on the regeneration of Pinus halepensis Mill. and resprouter species in recently thinned thickets / García-Jiménez, Ruth (Centre de Recerca Ecològica i d'Aplicacions Forestals) ; Palmero-Iniesta, Marina (Centre de Recerca Ecològica i d'Aplicacions Forestals) ; Espelta Morral, Josep Maria (Universitat Autònoma de Barcelona. Departament de Biologia Animal, de Biologia Vegetal i d'Ecologia)
Many studies have outlined the benefits for growth and reproduction resulting from thinning extremely crowded young forests regenerating after stand replacing wildfires ("thickets"). However, scarce information is available on how thinning may influence fire severity and vegetation regeneration in case a new fire occurs. [...]

16 p, 3.2 MB Mitigating the stress of drought on soil respiration by selective thinning: contrasting effects of drought on soil respiration of two oak species in a Mediterranean forest / Chang, C. T. (Centre de Recerca Ecològica i d'Aplicacions Forestals) ; Espelta Morral, Josep Maria (Universitat Autònoma de Barcelona. Departament de Biologia Animal, de Biologia Vegetal i d'Ecologia) ; Sperlich, Dominik (Centre de Recerca Ecològica i d'Aplicacions Forestals) ; Sabaté i Jorba, Santi (Centre de Recerca Ecològica i d'Aplicacions Forestals) ; Sànchez Costa, Elisenda (Centre de Recerca Ecològica i d'Aplicacions Forestals) ; Cotillas de la Torre, Miriam (Centre de Recerca Ecològica i d'Aplicacions Forestals) ; Gracia, Carles (Centre de Recerca Ecològica i d'Aplicacions Forestals)
Drought has been shown to reduce soil respiration (SR) in previous studies. Meanwhile, studies of the effect of forest management on SR yielded contrasting results. However, little is known about the combined effect of drought and forest management on SR. [...]

38 p, 1.7 MB The role of nutrients, productivity, and climate in determining tree fruit production in European forests / Fernández-Martínez, Marcos (Centre de Recerca Ecològica i d'Aplicacions Forestals) ; Vicca, Sara (Universiteit Antwerpen. Departement Biologie) ; Janssens, Ivan (Universiteit Antwerpen. Departement Biologie) ; Espelta Morral, Josep Maria (Centre de Recerca Ecològica i d'Aplicacions Forestals) ; Peñuelas, Josep (Centre de Recerca Ecològica i d'Aplicacions Forestals)
Fruit production (NPPf), the amount of photosynthates allocated to reproduction (%GPPf) and their controls for spatial and species-specific variability (e. g. nutrient availability, climate) have been poorly studied in forest ecosystems. [...]

32 p, 920.1 KB The North Atlantic Oscillation synchronises fruit production in western European forests / Fernández-Martínez, Marcos (Centre de Recerca Ecològica i d'Aplicacions Forestals) ; Vicca, Sara (Universiteit Antwerpen. Departement Biologie) ; Janssens, Ivan (Universiteit Antwerpen. Departement Biologie) ; Espelta Morral, Josep Maria (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)
Weather and its lagged effects have been associated with interannual variability and synchrony of fruit production for several tree species. Such relationships are used often in hypotheses relating interannual variability in fruit production with tree resources or favourable pollinating conditions and with synchrony in fruit production among sites through the Moran effect (the synchronisation of biological processes among populations driven by meteorological variability) or the local availability of pollen.

(Museo Nacional de Ciencias Naturales (Madrid, Espanya))
Climate change is expected to alter the geographic distribution of many plant species worldwide. However, there is still no clear evidence showing a generalised direction and magnitude of these distribution shifts. [...]

24 p, 680.5 KB Temporal trends in the Enhanced Vegetation Index and spring weather predict seed production in Mediterranean oaks / Fernández-Martínez, Marcos (Centre de Recerca Ecològica i d'Aplicacions Forestals) ; Espelta Morral, Josep Maria (Universitat Autònoma de Barcelona. Departament de Biologia Animal, de Biologia Vegetal i d'Ecologia) ; Garbulsky, Martín Fabio (Universidad de Buenos Aires. Cátedra de Forrajicultura) ; Peñuelas, Josep (Centre de Recerca Ecològica i d'Aplicacions Forestals) ; Peguero, Guille (Centre de Recerca Ecològica i d'Aplicacions Forestals)
The extremely year-to-year variable production of seeds (masting) is an extended plant reproductive behaviour important for forest dynamics and food webs. The dependence of these episodes of massive seed production on recently or long-term photosynthesised carbohydrates, however, remains controversial. [...]

13 p, 474.9 KB Identificación de los anillos anuales de crecimiento de la encina (Quercus ilex. L.) / Gené, Carles (Centre de Recerca Ecològica i d'Aplicacions Forestals) ; Retana Alumbreros, Javier (Universitat Autònoma de Barcelona. Departament de Biologia Animal, de Biologia Vegetal i d'Ecologia) ; Espelta Morral, Josep Maria (Centre de Recerca Ecològica i d'Aplicacions Forestals) ; Gràcia Moya, Marc (Centre de Recerca Ecològica i d'Aplicacions Forestals)
Las caracteristicas de la madera de encina (Quercus ilex L. ) hacen de muy difícil interpretación el patrón de crecimiento anual de esta especie. Con el fin de intentar encontrar un método práctico y, al mismo tiempo, fiable para la identificación de los anillos anuales de crecimiento de la encina, se han seguido dos aproximaciones: el estudio de discos enteros de troncos y el de testigos de madera recogidos con barrena Pressler. [...]
The growth pattem of the holm oak (Quercus ilex L. ) is difficult to interpret due to varied features of its wood. In order to find a practical as well as reliable method for interpreting annual tree-rings of the holm oak, two approaches have been tried: the study of basal disks and the study of 5 mm-diarneter, and 12 mm-diameter cores taken with a Pressler borer.
