“…For future investigations, a visual examination of some intra-ring features such as latewood events, and wood density measurements may provide better information on ring disturbance (Schweingruber 1979), since defoliation affects latewood density and earlywood anatomy differently (Filion and Cournoyer 1995;Liang et al 1997), as demonstrated by experimental defoliation of larch and pine (Craighead 1940;Polge et al 1971). Since methods described in this paper are applicable to both single tree data as well as master chronologies, a reinvestigation of previously published data on ring widths and densitometric master chronologies might be of general interest in view of the reconstruction of LBM outbreaks throughout the Alps (Baltensweiler and Rubli 1999).…”

In the Alps, larch (Larix decidua Mill.) forests show periodic discolouration due to larch budmoth (LBM) outbreaks (Zeiraphera diniana Guénée, Lepidoptera: Tortricidae). Tree defoliation causes severe reductions in radial growth, visible in tree rings. This paper aims at reconstructing LBM outbreak history, and critically examining the potential for using dendrochronological data by comparing tree-ring estimates with insect surveys. The occurrence of LBM outbreaks was investigated using 249 cores from larch growing near the timberline in three regions of the French Alps (Briançonnais, Maurienne, and Tarentaise). Years with an abrupt decrease in radial growth (-40%) were considered as negative pointer years reflecting the potential impact of LBM. The comparison with three non-host conifers (Norway spruce, stone and mountain pines) permitted us to distinguish growth reductions in larch due to climatic effects from those due to defoliation by LBM. The dendrochronological data were matched with information reporting conspicuous discolouration in old forestry reports or recovered from systematic field observations. Twenty-two outbreaks are discernible within the period 1800-1983. A peak reduction in larch growth occurred at intervals of 8.86±1.Our objective method based on ring measurements and comparison with non-host trees was compared with qualitative techniques based on the visual detection of conspicuous latewood anomalies. Larch in the Briançonnais (which experiences a continental climate) are infested first, whereas the Tarentaise region exhibits a much weaker impact of LBM. Complete tree recovery was observable 3 years after outbreak peaks.

“…As a consequence, several studies have used special features or anomalies in radial growth for ecological and climatological interpretation [11,60,61]. Such studies have included frost rings [9,35], light rings [20,36,58,64], and the formation of intra-annual density fluctuations (IADFs) [12,46,47,62]. In the literature IADFs have also been referred to as "double rings" [22], "false rings" [51], "multiple growth layers" [26], "multiple rings" [32] or "intra-annual growth bands" [23].…”

Climatic significance of tree-ring width and intra-annual density fluctuations in Pinus pinea from a dry Mediterranean area in Portugal

-In Mediterranean climates trees may go through two periods of dormancy, resulting in special anatomical features such as false rings and other intra-annual density fluctuations (IADFs). In this paper, ring growth and the presence of IADFs were studied in Pinus pinea L. growing in the coastal and inland regions of Alentejo (southern Portugal). In order to identify the triggering factors associated with the IADFs, a new classification was proposed for the IADFs in P. pinea: Type E (latewoodlike cells within earlywood); Type E+ (transition cells between earlywood and latewood); Type L (earlywoodlike cells within latewood) and Type L+ (earlywoodlike cells between latewood and earlywood of the next tree ring). Response function analyses showed that radial growth of P. pinea was strongly correlated with precipitation in southern Portugal. The climatic response of P. pinea was higher in the inland area where the summer drought is more severe, the winter temperatures are lower and the soils have low water-holding capacity, in comparison with the coastal area. IADFs were frequent in P. pinea and most of the IADFs were observed in latewood. The presence of IADFs was correlated with fluctuations in climate parameters during the growing season. The IADF type E+ was linked to precipitation events early in summer. The IADF type L and L+ were associated with above-average precipitation in early autumn.false tree-ring / Mediterranean climate / Pinus pinea / radial growth / wood anatomy Résumé -Signification climatique de la largeur des cernes et des fluctuations intra annuelles de la densité chez Pinus pinea dans une région méditerranéenne sèche du Portugal. Dans les climats méditerranéens, les arbres peuvent traverser deux périodes de dormance, ce qui a pour consé-quence des caractéristiques anatomiques particulières telles que des faux cernes et des fluctuations intra annuelles de densité (IADFs). Dans cet article, la croissance des cernes et la présence de IADFs ont été étudiées chez Pinus pinea L. poussant dans les régions côtières et intérieures de l'Alentejo (sud-ouest du Portugal). Dans le but d'identifier les facteurs déclenchants associés à l'IADFs, une nouvelle classification a été proposée pour l'IADFs chez Pinus pinea : Type E (cellules ressemblant à du bois final dans le bois initial) ; Type E+ (cellules de transition entre bois initial et bois final) ; Type L (cellules ressemblant à du bois initial dans du bois final) et Type L+ (cellules ressemblant à du bois initial entre bois final et bois initial du prochain cerne). Les analyses des fonctions de réponse ont montré que la croissance radiale de Pinus pinea était fortement corrélée avec les précipita-tions dans le sud-ouest du Portugal. La réponse climatique de Pinus pinea a été plus forte dans la zone intérieure où la sécheresse d'été est plus sévère, les températures hivernales plus basses et où les sols ont une plus faible capacité de rétention de l'eau, comparativement aux zones côtières. IADFs a été fréquent chez Pinus pinea et la majorité d'IADFs ...

“…Since intra-annual climatic information is difficult to obtain from TRW, other anatomical features have been used to derive signals with a higher temporal resolution (Wimmer 2002). Among these are frost rings (LaMarche and Hirschboeck 1984;Brunstein 1996), light rings (Liang et al 1997;Wang et al 2000;Liang and Eckstein 2006), double or false rings (Wimmer et al 2000;Masiokas and Villalba 2004;Campelo et al 2007a) and intra-annual density fluctuations (Bouriaud et al 2005;Campelo et al 2007b;Vieira et al 2009). The identification of such anatomical structures in wood is based on cell characteristics (e.g.…”

We investigated whether vessel time series of Holm oak (Quercus ilex L.), a diffuse to semi-ring-porous species, can record a climatic signal which differs from the signal encoded in tree-ring width (TRW). The study was conducted in ten Q. ilex trees from a coppice stand in northeast Spain. Chronologies of TRW, mean vessel area (MVA) and maximum vessel area (MAX) were developed and correlated with climate data, for the period 1985-2004 (20 years). Our results indicate that vessel features contain environmental information that is different from that stored in TRW. MAX chronologies correlate better to early spring precipitation (April-May) than TRW chronologies, and so does MVA of the largest 20-25 vessels from the first third of the ring with late spring precipitation (May-June). Also, the combination of MVA and TRW is a better predictor of summer precipitation. This explorative study clearly shows that vessel features can complement the climatic signal of TRW increasing the resolution of the climate reconstructions for the Mediterranean region.
