TLDR
The long-term history of Zeiraphera diniana Gn.Abstract:
The long-term history of Zeiraphera diniana Gn. (the larch budmoth, LBM) outbreaks was reconstructed from tree rings of host subalpine larch in the European Alps. This record was derived from 47513...read more

Complex climate controls on 20th century oak growth in Central-West Germany
TL;DR: The wider oak rings that are exhibited during this period may be indicative of a nonlinear or threshold-induced growth response to drought and vapor pressure, and run counter to the general response of oak to droughtand precipitation that normally would result in suppressed growth in a warmer and drier environment.
Journal ArticleDOI
Climate change could alter the distribution of mountain pine beetle outbreaks in western Canada
TL;DR: In this paper, the authors studied the individual associations of several biologically-relevant cold temperature variables, and other temperature/degree-day terms, with outbreak occurrences in a spatial-temporal logistic regression model using data from the current outbreak.

A tree-ring perspective on the terrestrial carbon cycle
Flurin Babst,M. Ross Alexander,Paul Szejner,Olivier Bouriaud,Stefan Klesse,John S. Roden,Philippe Ciais,Benjamin Poulter,David Frank,David J. P. Moore,Valerie Trouet +10 more
TL;DR: Recent advances are summarized and promising paths of investigation are highlighted with respect to growth phenology, forest productivity trends and variability, CO2 fertilization and water-use efficiency, forest disturbances, and comparisons between observational and computational forest productivity estimates.

Forest tree responses to extreme drought and some biotic events: Towards a selection according to hazard tolerance?
Nathalie Bréda,Vincent Badeau +1 more
TL;DR: A coupled approach linking dendrochronology and ecophysiology helps in discussing vulnerability of forest stands, and suggests management advices in order to mitigate extreme drought and cope with selective mortality.

Climatic warming disrupts recurrent Alpine insect outbreaks
Derek M. Johnson,Ulf Büntgen,David Frank,Kyrre Kausrud,Kyle J. Haynes,Andrew M. Liebhold,Jan Esper,Nils Chr. Stenseth +7 more
TL;DR: A population model supports the hypothesis that temperature-mediated shifting of the optimal elevation for LBM population growth is the mechanism for elevational epicenter changes, thereby causing the collapse of a millennium-long outbreak cycle.

Herbivory in global climate change research: direct effects of rising temperature on insect herbivores
J. S. Bale,Gregory J. Masters,Ian D. Hodkinson,Caroline S. Awmack,T. Martijn Bezemer,Valerie K. Brown,Jennifer Butterfield,Alan Buse,John C. Coulson,John Farrar,John E. G. Good,Richard Harrington,Susane Hartley,T. Hefin Jones,Richard L. Lindroth,Malcolm C. Press,Ilias Symrnioudis,Allan D. Watt,J. B. Whittaker +18 more
TL;DR: Future research needs to consider insect herbivore phenotypic and genotypic flexibility, their responses to global change parameters operating in concert, and awareness that some patterns may only become apparent in the longer term.

European seasonal and annual temperature variability, trends, and extremes since 1500.
TL;DR: Multiproxy reconstructions of monthly and seasonal surface temperature fields for Europe back to 1500 show that the late 20th- and early 21st-century European climate is very likely (>95% confidence level) warmer than that of any time during the past 500 years.
