Increase in abiotic and biotic stress driven by global change threatens forest ecosystems and challenges understanding of mechanisms producing mortality. Phytophthora spp. like P. cinnamomi (PHYCI) are among the most lethal pathogens for many woody species including Quercus spp. Dynamics of biotic agents and their hosts are complex and influenced b...

Condiciones climáticas extremas, u otras causas como ataques severos de plagas, pueden ocasionar que el cambium vascular de un determinado individuo o especie no llegue a activarse durante todo un periodo vegetativo, dando lugar a un anillo ausente. La presencia y frecuencia de aparición de anillos ausentes puede ser de esta forma considerada como...

Diversification of genetic plant material in forest plantations is viewed as a promising strategy to promote forest adaptation and resilience to ongoing climate change. However, there is an intense debate about whether foreign populations might outperform local ones under new climatic conditions. Unfortunately , long-term experiments using contrast...

Predicting trends of Mediterranean tree growth under warmer climate in the Iberian Peninsula is important to implement adaptive management systems in forestry. Tree-ring series reflect effects of climate variations on growth and thus permit to build models for long-term predictions. Building models can be accomplished by classic dendroclimatologica...

Estudiar las tendencias del crecimiento de los árboles es importante para proporcionar fundamento científico a la gestión forestal sostenible. La dendrocronología es la ciencia que se ocupa de medir y datar los anillos de crecimiento de las especies leñosas. La investigación dendrocronológica de las relaciones entre crecimiento y factores ecológico...

Climate warming and increasing aridity have impacted diverse ecosystems in the Mediterranean region since at least the 1970s. Pinus pinea L. has significant environmental and socio-economic importance for the Iberian Peninsula, so a detailed understanding of its response to climate change is necessary to predict its status under future climatic con...

Forest decline and increasing tree mortality are of global concern and the identification of the causes is necessary to develop preventive measures. Global warming is an emerging factor responsible for the increasing tree mortality in drought-prone ecosystems. In the southwestern Iberian Peninsula, Mediterranean holm oak open woodlands currently un...

Processes and dynamics of the natural environment can be studied through the information stored in tree rings. Since radial stem increment is influenced by a number of external factors, extracting from a tree-ring chronology the information related to one of those factors requires the retention of the chronology variance linked to that single facto...

In the Iberian Peninsula, Western Mediterranean, Pinus pinea woodlands have a great environmental and socio-economic value. There is a need to know the impacts of climate change on the ecology of this species and to develop management options that may improve its sustainability. In this work we provide an assessment of the acclimation capacity and...

Understanding the response of Mediterranean forests to climate change is required to assess their vulnerability and to develop measures that may limit the impact of future climate change. We analyzed the sensitivity of several populations of Pinus pinea (Stone pine) in Southern and Central Spain and Portugal to climate and identified some responses...

Recently, vegetation in the Iberian Peninsula has exhibited global-change-type processes including species distribution shifts, altered plant phenology and enhanced forest decline and tree mortality. Studies based on long-term data sets, like tree rings, are providing evidences about the implication of climate change in these mechanisms. Dendrochro...

The adaptive response of forests to climate change can be accessed through the study of dendroclimatic signal. Primary data and standardization methods influence the information content of dendroclimatic signals. We measured earlywood (EW), latewood (LW) and tree-ring (TR) widths in two 140-year-old even-aged Pinus pinea stands in SW Spain and test...

Researching the dynamic response to climatic variability of Mediterranean pine forests is a basic issue when evaluating the vulnerability of these ecosystems to climate change-induced abiotic stress. Tree-rings can provide valuable information to approach this purpose. We established five Pinus pinea ring-width chronologies in SW Spain. Tree-growth...

The heterogeneous response of species to climate variability across their geographical distribution range is the result of phenotypic plasticity, which can be defined as the range of phenotypes that a single genotype can express as a function of local environmental conditions. In the actual climate change context, phenotypic plasticity of plant spe...

El patrimonio forestal del sur de España se encuentra amenazado por el cambio global. En ese contexto, destaca la importancia de evaluar la vulnerabilidad de las masas forestales y sus respuestas al clima. En este trabajo se estudió una cronología de Pinus pinea en Huelva, con el fin de estudiar cómo varía su productividad en relación con el clima....

We present two chronologies of dead and weakened Quercus ilex trees from declining open woodlands of Southern Andalusia and discuss climate's implication in the current widespread mortality in these ecosystems. Basal area increments were used to find out periods of growth decline preceding death. Absent rings became frequent since the 1970s, coinci...

Reflecting the transformation in the forest and environmental sector, and especially the great change the Italian and European university as whole undergone over the last 10 years with the Bologna Process, big changes are afoot in forestry education in Italy. In spite of this, no studies attempted to explain how these mutations are affecting tertia...

AUSF Italia e Redazione di Sherwood hanno realizzato un questionario per raccogliere le opinioni degli studenti sul proprio corso di laurea e sulle scelte personali, sulle aspettative nei confronti della formazione e sul futuro impegno professionale. In questo contributo oltre a descrivere la modalità operativa si riportano i principali risultati e...
