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

Xylem Vessels Segmentation Through a Deep Learning Approach: a First Look
Angel Garcia-Pedrero,Ana I. García-Cervigón,Cristina Caetano,Saul Calderon-Ramirez,José Miguel Olano,Consuelo Gonzalo-Martin,Mario Lillo-Saavedra,Miguel García-Hidalgo +7 more
TL;DR: A Convolutional Neural Network model was used to process digital images of 23 branch sections in order to segment the xylem vessels and the obtained results show the potential of convolutional neural networks to overcome aspects such as non-homogeneous illumination of images, where conventional methods tend to obtain unsatisfactory results.

Drought and surface-level solar radiation predict the severity of outbreaks of a widespread defoliating insect
TL;DR: The nonlinear relationship between summer drought severity and growth suppression the following year suggests a future in which summer droughts precede severe outbreaks that threaten the health of boreal forest hardwood trees.

Mammal Ecology as an Indicator of Climate Change
TL;DR: Fruit bats, like other mammals and birds, use a combination of physiological and behavioral mechanisms to regulate their body temperature, which decouples their core body temperature from air temperature.

The influence of increasing temperature and CO2 concentration on recent growth of old-growth larch: contrasting responses at leaf and stem processes derived from tree-ring width and stable isotopes
Rosemarie Weigt,Rosemarie Weigt,Kathrin Streit,Matthias Saurer,Matthias Saurer,Rolf T. W. Siegwolf,Rolf T. W. Siegwolf +6 more
TL;DR: The approach demonstrates that the identification of different roles of environmental factors on leaf and stem processes helps to improve the assessment of site-specific changes of carbon fluxes and growth performance under future environmental conditions.
Journal ArticleDOI
Thinking long term
TL;DR: In this article, a thousand-year records of animal population patterns and climate yield insights into the impacts of environmental change, and the authors propose a method to predict the impact of environmental changes on animals.

Herbivory in global climate change research: direct effects of rising temperature on insect herbivores

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.
