“…This method was used with a 10-, 20-, and 30-year filter to analyze the mean summer air temperatures for the Italian Central Alps (1610–2008; Coppola et al 2013). For northern Alaska, a 5- and 10-year moving average produced smoothed curves with significant R 2 values for the Barrow data (Fig.…”

Long-term measurements of ecological effects of warming are often not statistically significant because of annual variability or signal noise. These are reduced in indicators that filter or reduce the noise around the signal and allow effects of climate warming to emerge. In this way, certain indicators act as medium pass filters integrating the signal over years-to-decades. In the Alaskan Arctic, the 25-year record of warming of air temperature revealed no significant trend, yet environmental and ecological changes prove that warming is affecting the ecosystem. The useful indicators are deep permafrost temperatures, vegetation and shrub biomass, satellite measures of canopy reflectance (NDVI), and chemical measures of soil weathering. In contrast, the 18-year record in the Greenland Arctic revealed an extremely high summer air-warming of 1.3 °C/decade; the cover of some plant species increased while the cover of others decreased. Useful indicators of change are NDVI and the active layer thickness.

“…Considered as a species with high dendrochronological potential due to its high longevity (N1000 years, Tranquillini, 1979;Rolland et al, 1998) and high temperature sensitivity , L. decidua trees growing at high-elevation sites in the Alps have been used repeatedly for climatic reconstructions (e.g., Büntgen et al, 2005;Corona et al, 2010aCorona et al, , 2010bDaux et al, 2011;Büntgen et al, 2011;Coppola et al, 2013). At the same time, detailed studies have been undertaken to understand the response of L. decidua to climate in the Eastern Italian (Anfodillo et al, 1998;Urbinati, 2004, 2006), Eastern Austrian (Nicolussi et al, 2009), Swiss (Büntgen et al, 2005;Garbarino et al, 2013), Southeastern German (Hartl-Meier et al, 2014), Southeastern Slovenian Alps (Hafner et al, 2011), and in lowland sites of Poland and Lithuania (Koprowski, 2012;Vitas, 2018).…”

A better understanding of the respective role of key climatic variables on tree growth is crucial for an accurate assessment of how ongoing global changes may affect both dynamics and distribution of forest tree species in the future. The aim of this study was (i) to explore growth patterns of European larch (Larix decidua Mill.) through a network of tree-ring chronologies developed for the French Alps and (ii) to identify the main climatic drivers explaining radial growth. Climate-growth relationships were coupled with a hierarchical analysis. This relationship revealed significant variability expressed spatially by the existence of five clusters, initially discriminated by an elevational contrast related to (i) a negative correlation between summer temperatures and larch growth at lower elevations and (ii) a stronger response of low-elevation larch stands to winter precipitation. In the high-elevation clusters, tree growth depends on previous autumn and current summer temperatures and water supply in July. The differentiation, that portrays a strong geographical coherence, is mainly related to the latitudinal gradient; (i) the northwestern stands are mostly sensitive to high temperatures in summer; (ii) the growth of the southernmost clusters is equally driven by temperatures during autumn, winter, and summers; (iii) the populations of a cluster located in a transitional zone of the inner French Alps, subject to both

“…In fact, different species could be characterized by different response to the same climatic conditions . Larch and spruce in the study area are known to have a similar response to climate , Büntgen et al 2006, Coppola et al 2013. Although both spruce and larch chronologies showed a strong correlation with June temperature (up to r̄ = 0.40) and in general with June-August mean summer temperature (r̄ = 0.34 for larch chronologies and r̄ = 0.37 for Norway spruce), correlation between the chronologies of the two different species was low and not significant (r̄ = 0.15), suggesting a rather distinct response to environmental factors by the two species.…”

Biogeosciences and Forestry Biogeosciences and Forestry Tree-ring-based reconstruction of larch budmoth outbreaks in the Central Italian Alps since 1774 CE Riccardo Cerrato (1) , Paolo Cherubini (2-3) , Ulf Büntgen (2-4-5) , Anna Coppola (1) , Maria Cristina Salvatore (1-6) , Carlo Baroni (1-6) The larch budmoth (Zeiraphera diniana Gn.-LBM) offers a unique example of cyclic fluctuations in insect populations. During regular LBM mass outbreaks, defoliation of European larch (Larix decidua Mill.) subalpine trees results in distinct ring-width reductions in the host trees. Although several observations, reconstructions and models suggest that LBM outbreaks travel from the southwest to the northeast along the Alpine arc, gaps in the underlying data still hamper our mechanistic understanding of the spatio-temporal system dynamics. Evidence of historical LBM outbreaks before 1964 is generally associated with uncertainty and is particularly scarce for the Central Italian Alps. Here, we introduce four new larch ring-width chronologies from Val di Sole in the Central Italian Alps and use time-series analyses and comparisons with nonhost trees (Picea abies Karst.) to reconstruct LBM mass outbreaks. We identify distinct fingerprints of 15 spatially-synchronized LBM events that occurred between 1774 and 1964 CE. Our results are important for improving qualitative space-time models to simulate travelling wave dynamics of insect populations, and for correcting ring-width-based summer temperature reconstructions from this part of the Alpine arc.
