Dendrochronology generally operates under the assumption that climate–growth relationships are age independent, once growth trends and/or disturbance pulses have been accounted for. However, several studies demonstrated tree physiology undergoes changes with age. This may cause growth-related climate signals to vary over time. Using chronology statistics and response functions, we tested consistency of responses in tree-ring series from Larix decidua Pinus cembra trees four classes....
Aim To evaluate the climate sensitivity of model-based forest productivity estimates using a continental-scale tree-ring network. Location Europe and North Africa (30–70° N, 10° W–40° E). Methods We compiled close to 1000 annually resolved records radial tree growth for all major European species quantified changes in as function historical climatic variation. Sites were grouped neural network clustering technique isolate spatiotemporal species-specific response patterns. The resulting...
• Tree rings are widely used long-term proxy data which, if combined with instrumental climate records, can provide excellent information on global variability. This research aimed to determine whether interannual climate–growth responses in Alpine treeline forests stationary over time. We tree-ring width chronologies of Larix decidua (European larch) from 17 sites and monthly temperatures precipitation for the period 1800–1999. Climate–growth relationships were assessed correlation response...
Abstract Evidence for reduced sensitivity of tree growth to temperature has been reported from multiple forests along the high northern latitudes. This alleged circumpolar phenomenon described apparent inability temperature‐sensitive tree‐ring width and density chronologies parallel increasing instrumental measurements since mid‐20th century. In addition such low‐frequency trend offset, formerly reflect high‐frequency signals in a warming world is indicated at some boreal sites, mainly...
Abstract Aim Climate change is expected to modify growth trends of forests around the world. However, this modification may vary in strength and intensity across a species' biogeographical range. Here, we study European populations silver fir ( Abies alba ) its southern distribution limits Spain, Italy Romania. We hypothesized that will differ range, with marked decline drought‐prone regions near southernmost limits. Location Europe (Spain, Italy, Romania). Methods collected tree‐ring data...
Abstract Recent observations of tree regeneration failures following large and severe disturbances, particularly under warm dry conditions, have raised concerns about the resilience forest ecosystems their recovery dynamics in face climate change. We investigated temperate forests Europe after disturbance events (i.e., resulting more than 70% canopy loss patches larger 1 ha), with a range one to five decades since occurred. The study included 143 sites different types management practices...
1 The tree-ring growth response of stone pine (Pinus cembra L.) to climatic variability was studied in the Alps. aims were (i) assess patterns at different spatial-temporal scales; (ii) identify climate parameters that explain most radial time domains; and (iii) study past current trends climate–growth relationships locations. 2 High- low-frequency chronologies compiled for 30 treeline sites on French Italian We used gridded data computed from 200 years instrumental records an extensive...
Silver fir Abies alba is an indigenous tree species present in many southern European mountain forests. Its distribution area and its adaptive capacity to climate variability, expressed tree-ring growth series, make it a very suitable target for studying responses particularly complex like the Mediterranean basin where significant changes are expected. We used set of 52 site chronologies (784 trees) Italian Alps Apennines (38.1°– 46.6°N 6.7°– 16.3°E) temperature precipitation monthly data...
Knowledge of the persistence regular larch budmoth outbreaks is limited in space and time. Although dendrochronological methods have been used to reconstruct insect outbreaks, their presence may be obscured by climatic influences. More than 5000 tree-ring series from 70 host 73 spruce nonhost sites within European Alps Tatra Mountains were compiled. Site-specific assessment growth-climate responses application six detection considering host, instrumental time-series revealed spatiotemporal...
Abstract. This paper presents a reconstruction of the summer temperatures over Greater Alpine Region (44.05°–47.41° N, 6.43°–13° E) during last millennium based on network 38 multi-centennial larch and stone pine chronologies. Tree ring series are standardized using an Adaptative Regional Growth Curve, which attempts to remove age effect from low frequency variations in series. The proxies calibrated June August mean HISTALP high-elevation temperature time spanning 1818–2003. method combines...
Understanding post-fire regeneration dynamics is an important task for assessing the resilience of forests and to adequately guide post-disturbance management. The main goal this research was compare ability different Landsat-derived spectral vegetation indices (SVIs) track recovery occurring in burned central Apennines (Italy) at development stages. Normalized Difference Vegetation Index (NDVI), Moisture (NDMI), Burn Ratio (NBR), 2 (NBR2) a novel index called Forest Recovery (FRI2) were...
Trees growing at the alpine timberline very seldom undergo severe water stress because of high precipitation during vegetative period.Since trees are adapted to moist con- ditions, moderate deficit may lead a strong reduction in transpiration.Transpiration and xylem potential were measured two individuals each Pinus cembra, Larix decidua Picea abies (2 080 m a.s.l.) north-eastern Italian Alps.From June October 1996 predawn was between -0.29 -1.0 MPa with differences among species.Throughout...
Climatic extreme events strongly affect forest growth and thus significantly influence the inter-annual terrestrial carbon balance. As we are facing an increase in frequency intensity of climate extremes, extensive empirical archives required to assess continental scale impacts temperature precipitation anomalies. Here divide a tree-ring network approximately 1000 sites into fifteen groups similar high-frequency variability reconstruct regional positive negative different parts Europe...
Abstract Aim Mediterranean refugial areas are generally underrepresented in large‐scale genetic surveys of forest trees. In the case silver fir ( Abies alba Mill.), this has led to divergent hypotheses about exact location glacial refugia and trajectory recolonization routes. Based on comprehensive sampling Apennine populations, we aimed reconcile discrepancies number for Apennines test alternative demographic scenarios developed from palaeobotanical data. Location Basin; surrounding areas....
In recent years, advancements in remote and proximal sensing technology have driven innovation environmental land surveys. The integration of various geomatics devices, such as reflex UAVs equipped with RGB cameras mobile laser scanners (MLS), allows detailed precise surveys monumental trees. With these data fusion method, we reconstructed three 3D tree models, allowing the computation metric variables diameter at breast height (DBH), total (TH), crown basal area (CBA), volume (CV) wood...
ABSTRACT Aims Forests classified as Natura 2000 priority Habitat 9210* (Apennine beech forests with Taxus baccata and Ilex aquifolium ) cover most of the European distribution along Italian peninsula. Most these have been coppiced for centuries until 60–70 years ago, today, some are lapsed coppices others in conversion to high forests. In both cases there is a lack knowledge on ongoing ecological dynamics, especially regard species composition changes, that base their sustainable management....
Abstract Questions How do climate, topography and human impact affect land‐cover changes, elevation of treelines dominant tree species composition at multiple spatial scales? Location Apennine Mountains, Italy. Methods At the regional scale ( n = 776 municipalities covering 43,000 km 2 ), we assessed relationship between demographic processes forest cover dynamics for 1990–2012 period using Corine Land Cover maps a national census data set. landscape 18 units 16 each), tested effects site on...
The quantitative assessment of wood anatomical traits offers important insights into those factors that shape tree growth. While it is known conduit diameter, cell wall thickness, and density vary substantially between within species, the interconnection traits, tree-ring width, height age, as well environment effects on anatomy remain unclear. Here, we measure derived 65 in cross-sections five outermost rings (2008–2012) 30 Norway spruce (Picea abies (L.) H. Karst.) trees growing along an...
