Autor: Allan Buras, Marieke van der Maaten-Theunissen, Ernst van der Maaten, Svenja Ahlgrimm, Philipp Hermann, Sonia Simard, Ingo Heinrich, Gerd Helle, Martin Unterseher, Martin Schnittler, Pascal Eusemann, Martin Wilmking

Publikováno v: PLoS ONE, Vol 11, Iss 7, p e0158346 (2016)

This paper introduces a new approach-the Principal Component Gradient Analysis (PCGA)-to detect ecological gradients in time-series populations, i.e. several time-series originating from different individuals of a population. Detection of ecological

Can We Use Tree Rings of Black Alder to Reconstruct Lake Levels? A Case Study for the Mecklenburg Lake District, Northeastern Germany.

Autor: Ernst van der Maaten, Marieke van der Maaten-Theunissen, Allan Buras, Tobias Scharnweber, Sonia Simard, Knut Kaiser, Sebastian Lorenz, Martin Wilmking

Publikováno v: PLoS ONE, Vol 10, Iss 8, p e0137054 (2015)

In this study, we explore the potential to reconstruct lake-level (and groundwater) fluctuations from tree-ring chronologies of black alder (Alnus glutinosa L.) for three study lakes in the Mecklenburg Lake District, northeastern Germany. As gauging

DendrometeR: Analyzing the pulse of trees in R

Autor: Annie Deslauriers, Ernst van der Maaten, Sonia Simard, Marieke van der Maaten-Theunissen, Olivier Bouriaud, Georg von Arx, Martin Wilmking, Marko Smiljanic, Patrick Fonti, Sergio Rossi

Publikováno v: Dendrochronologia

Dendrometers are measurement devices proven to be useful to analyze tree water relations and growth responses in relation to environmental variability. To analyze dendrometer data, two analytical methods prevail: (1) daily approaches that calculate o

Tree-ring widths and isotopes of artificially defoliated balsam firs: A simulation of spruce budworm outbreaks in Eastern Canada

Autor: Kerstin Treydte, Cornelia Krause, Sonia Simard, Hubert Morin, William M. Buhay

Publikováno v: Environmental and Experimental Botany. 81:44-54

Defoliation by insects is a major disturbance influencing the forest dynamics in many ecosystems and can affect forest productivity worldwide. The main objective of this research was to further investigate the potential use of tree-ring widths and is

Wood formation in Abies balsamea seedlings subjected to artificial defoliation

Autor: Sergio Rossi, Annie Deslauriers, Sonia Simard, Hubert Morin

Publikováno v: Tree Physiology. 29:551-558

We determined the cambial sensitivity and quantified the anatomical differences in xylem of Abies balsamea (L.) Mill. seedlings subjected to artificial defoliation to simulate spruce budworm feeding. Defoliation was performed by removing two-thirds o
