Tree rings, carbon isotopes and wood chemistry reveal centuries of pollarding history in an ancient oak-holly woodland
Leaf phenology and tree growth are uncoupled in three deciduous tree species
Climate warming is expected to lengthen the phenological season of deciduous broadleaf trees. Such longer phenological seasons could also lead to higher growth rates. This hypothesis was tested by examining and relating leaf phenology and tree-ring width series of three European deciduous tree species ( Betula pendula , Fagus sylvatica , Quercus robur ). Leaf onset and fall dates were used to define the duration of the phenological season. Leaf p…
Lower growth and production of latewood intra-annual density fluctuations due to drought-triggered forest die-off
Hotter droughts and aridification are causing forest die-off episodes worldwide. These events are characterized by canopy dieback and elevated mortality rates, but not all trees are equally affected with neighboring conspecifics showing contrasting vigor. Tree-ring data have been used to forecast die-off because of the contrasting growth rates declining (D) and non-declining (ND) trees show before tree death. However, discrete wood features such …
Historical forest use constrains tree growth responses to drought
Resin extraction from Pinus pinaster (maritime pine) trees was an important economic activity for most of the 20th century in Mediterranean forests, until the decrease in resin prices that led to their abandonment in the 1960s-1970s. Reduced tree growth is often observed after long periods of resin tapping, but it is unknown how these formerly tapped stands respond to recent climate warming and aridification. We sampled three historically tapped …
Contrasting state land and fire use policies condition fire regime seasonality and size in two Central Spain forest landscapes
Testing annual tree-ring chemistry by X-ray fluorescence for dendroclimatic studies in high-elevation forests from the Spanish Pyrenees
How do Droughts and Wildfires Alter Seasonal Radial Growth in Mediterranean Aleppo Pine Forests?
Climate models project increasing temperatures, evapotranspiration, and droughts for the Mediterranean Basin, which will trigger more frequent and dangerous fire events. Here, we evaluate the combined effects of drought and wildfire on seasonal tree growth on Aleppo pine stands at the intra- and inter-annual level. Indexed earlywood width (EWI), latewood width (LWI), and latewood proportion (LWPI) series were obtained from unburned and burned sta…
Subalpine forest dynamics reconstructed throughout the last 700 years in the Central Pyrenees by means of tree rings and pollen
Understanding how climate has modulated forest growth and composition in the past is necessary to predict the influence of the ongoing climate warming on the dynamics of mountain forests. We studied the past dynamics of subalpine Pyrenean forests during the last 700 years by assessing the relationships between sedimentary pollen and tree-ring records, and their link with climatic drivers. We compared the pollen record and the montane pollen ratio…
Divergent Fire Regimes in Two Contrasting Mediterranean Chestnut Forest Landscapes
Humans have historically played a critical role in the management of Mediterranean-type ecosystems (MTEs) through traditional fire use. Although chestnut forests are widespread across the Mediterranean Basin, little is known about their historical fire regimes. Our goal here is to generate testable hypotheses about the drivers of fire regime dynamics in chestnut dominated ecosystems. To examine anthropogenic fire management we selected two sites …
Climate controls on tree growth in the Western Mediterranean
The first large-scale network of tree-ring chronologies from the western Mediterranean (WM; 32°N–43°N, 10°W–17°E) is described and analyzed to identify the seasonal climatic signal in indices of annual ring width. Correlation and rotated empirical orthogonal function analyses are applied to 85 tree-ring series and corresponding gridded climate data to assess the climate signal embedded in the network. Chronologies range in length from 80 to 1129 …
Reconstructing Evaporation From Pine Tree Rings In Northern Mexico
Here we reconstructed evaporation using tree-ring width variability. Drought variability and its effects on forest growth have been mainly characterized by changes in precipitation and temperatures, whereas atmospheric drought and evaporation rates have been little investigated. The area of study corresponds to northern Mexico, a region where water resources are increasingly limited. We used correlation analyses to identify the months in which ev…

Spatial diversity of recent trends in Mediterranean tree growth
Increasing temperatures and shifting precipitation regimes define the Mediterranean Basin (MB) as one of the world's most sensitive climate change hot spots. Among various ecological effects, disruptions in the growth-climate response of Mediterranean forest species have been recently observed. Complex topographical and climatological factors, however, may result in contrasting patterns of recent tree growth, with their biotic and abiotic drivers…
Dendrochronology Course In Valsaín Forest, Segovia, Spain
This report describes an international summer course, “Tree Rings, Climate, Natural Resources, and Human Interaction”, held in Valsaín, Spain, in summer of 2012. The course, with 14 participants from three countries (Spain, Algeria, and Russia), included basic training in dendrochronology skills as well as applied projects in dendroclimatology, dendroecology and dendrogeomorphology.
Response of vegetation to drought time-scales across global land biomes
We evaluated the response of the Earth land biomes to drought by correlating a drought index with three global indicators of vegetation activity and growth: vegetation indices from satellite imagery, tree-ring growth series, and Aboveground Net Primary Production (ANPP) records. Arid and humid biomes are both affected by drought, and we suggest that the persistence of the water deficit (i.e., the drought time-scale) could be playing a key role in…
