Statistics in DendRochRonology


The course will take place from March 14th to 16th 2016 at the TUM in Freising (north of
Munich), Germany. As indicated by the title of the course, it will focus on statistical analyses
of tree-ring data within ‘R’. Amongst others, course participants will learn how to efficiently
calculate basic tree-ring statistics (e.g. glk, rbar, EPS), detrend tree-ring data using various
techniques, calculate master chronologies, perform climate correlation analyses including
transfer functions and stability tests, compare tree-ring series within and between sites, and
handle tree-rings using multi-variate techniques. Although we’ll focus on practical examples
in ‘R’, the course will also provide basic theoretical background to the different topics.
Lectures will be given from 9:00 to 17:00 in a PC-pool at the WZW (DGL 01:, including 3 short breaks (20 minutes) and one
lunch-break (1 hour). No prerequisites are expected as the course will start ‘from the scratch’
i.e. assuming no pre-experience of the participants. To allow for a maximum quality of
teaching, the amount of course participants is restricted to 20 (first come, first serve). Being
supported by TUM and ATR, the course is free of charge.

For registration, please send an e-mail to with subject ‘dendRo’ before 5th of
February. Registered participants will be supplied with additional information by mid of
February. If you have any queries, please don’t hesitate to contact me.

 The Tree-Ring Laboratory at Argentinean Institute for Ice, Snow and Environmental Sciences (IANIGLA) is pleased to host the Third American Dendrochronology Conference - AmeriDendro 2016. Located in the Cuyo region in western Argentina, Mendoza is the center of the Argentinian wine industry, known as one of the great wine capitals of the world. With its generous geography of mountains, eternal snow, valleys, rivers, deserts and oasis Mendoza offers different possibilities to enjoy 365 days a year. It is also near the Aconcagua, the highest mountain in the Americas.


Dendrochronological research has been carried out at the Tree-Ring Lab in IANIGLA since 1978, which is the first dendro lab in South America. IANIGLA has wide experience in hosting international meetings such as, the successful International Conference on Dendrochronology for the Third Millennium (2000) and the Second Binational (Argentina & Chile) Conference of Ecology (2004). During the Binational Conference of 2004, the numbers of participants surpassed 1200 people.


Date for the Third AmeriDendro: March 28 - April 1, 2016.

TRACE arrives in Poland for the second time!

It is our pleasure to invite you to TRACE 2016, to the Bia?owie?a Forest in eastern Poland. The TRACE 2016 conference will be held on 11-15 May 2016 in the heart of the Bia?owie?a National Park (UNESCO World Heritage Site and Biosphere Reserve) protecting the last natural forest in the European Lowlands which retains its primeval character, not to mention the largest free-living population of European bison, the biggest European land mammal.

1st International Course on Wood Ecology 2016


- a comparison on a global scale

organized by:


  • Fritz Schweingruber (plant anatomy)
  • Jiri Dolezal (phylogeny)
  • Holger Gärtner (disturbances)
  • Alan Crivellaro(image analysis)

Longevity and age of plants and cells within plants are essential to reconstruct plant and vegetation
dynamics. By counting annual rings and recognizing living cells it is possible to date the total age of plants
or the oldest remaining living tissue of herbs, dwarf shrubs, shrubs trees and lianas.

We offer a one-week class where we introduce participants to sample preparation for growth-ring counting,
sectioning, staining as well as ecologically and taxonomically oriented anatomical investigations in
stems and roots.
We discuss plant associations, growth forms in forests, meadows, on rocks and along alpine rivers. We
prepare and analyze (your own) material in a fully equipped field laboratory which is equipped with microtomes,
microscopes and microphotography. We demonstrate how slides can be analyzed with imageanalysis
software. In addition we try to explain anatomical structures of plants functionally on the base of
high quality permanent slides.

We are open to all plant-age related topics, so the final topics will be defined depending on the interests
of participants. In general we teach how to analyze ...
- allometric relationships along environmental gradients
- upward and northward migration of plants in relation to climate warming
- dynamics of plant populations in meadows, steppes, river beds, ruderal places etc.
- dynamics of fine root systems
- carbon allocation
- hydrological and nutritional economy (xylem/bark proportion, vessel size and lignin concentration)
- senescence in relation to age, plant size, phenology
- anatomical adaption to different environmental stress factors and phylogeny (incl. geomorphic processes)
- stem anatomical structures in relation to taxonomy and phylogeny
- spatio-temporal forest dynamics

Course fee: 700.- CHF (approx. 650.- Euro) incl. full accommodation (bed in double room, breakfast, lunch, dinner)
