Impact of climate change on larch budmoth cyclic outbreaks
Periodic outbreaks of the larch budmoth Zeiraphera diniana population (and the massive forest defoliation they engender) have been recorded in the Alps over the centuries and are known for their remarkable regularity. But these have been conspicuously absent since 1981. On the other hand, budmoth outbreaks have been historically unknown in the larches of the Carpathian Tatra mountains. To resol...
متن کاملWaves of larch budmoth outbreaks in the European alps.
Spatially extended population models predict complex spatiotemporal patterns, such as spiral waves and spatial chaos, as a result of the reaction-diffusion dynamics that arise from trophic interactions. However, examples of such patterns in ecological systems are scarce. We develop a quantitative technique to demonstrate the existence of waves in Central European larch budmoth (Zeiraphera dinia...
متن کاملExtension of New Zealand kauri (Agathis australis) tree-ring chronologies into Oxygen Isotope Stage (OIS) 3
New Zealand kauri (Agathis australis) is both long-lived and sensitive to climate so during the past two decades an extensive network of sites has been sampled for dendrochronological analyses. The network can be divided into three general groups based on the time period they cover— ‘modern’ kauri (MK), late-Holocene kauri (HK) and ‘ancient’ kauri (AK) from before the Last Glacial Maximum (LGM)...
متن کاملLow-frequency signals in long tree-ring chronologies for reconstructing past temperature variability.
Preserving multicentennial climate variability in long tree-ring records is critically important for reconstructing the full range of temperature variability over the past 1000 years. This allows the putative "Medieval Warm Period" (MWP) to be described and to be compared with 20th-century warming in modeling and attribution studies. We demonstrate that carefully selected tree-ring chronologies...
متن کاملMillennium-long summer temperature variations in the European Alps as reconstructed from tree rings
This paper presents a reconstruction of the summer temperatures over the Greater Alpine Region (44.05– 47.41 N, 6.43–13 E) during the last millennium based on a network of 38 multi-centennial larch and stone pine chronologies. Tree ring series are standardized using an Adaptative Regional Growth Curve, which attempts to remove the age effect from the low frequency variations in the series. The ...
