Margaux Didion-Gency: Interactive effects of tree species mixture and climate on foliar and woody trait variation in a widely distributed deciduous tree.

Margaux Didion-Gency, Ph.D. at the Swiss Federal Institute for Forest, Snow and Landscape Research (WSL) of Birmensdorf (Switzerland), presents her first published paper and discusses the importance of tree species interactions in the context of climate change. About the paper This study was motivated by previous research that reported the positive effect of species richness on grassland resistance to extreme events. However, we noticed that … Continue reading Margaux Didion-Gency: Interactive effects of tree species mixture and climate on foliar and woody trait variation in a widely distributed deciduous tree.

Lymantria dispar (caterpillar shown here) is one of the most destructive invasive insects in North America. Defoliation by this insect can kill oak trees by draining the trees’ energy reserves. Photo credit: Nathan Oalican.

Audrey Barker Plotkin: Trees can starve to death from insect defoliation

In this post, Audrey Barker Plotkin of Harvard University talks to us about her latest research where she investigates how invasive insects can starve trees and the importance of protecting temperate forest land. I’m a forest ecologist based at the Harvard Forest in the northeastern United States. Because of high levels of global trade and forest cover, our region is especially vulnerable to forest insect … Continue reading Audrey Barker Plotkin: Trees can starve to death from insect defoliation

Thomas Caignard: opposite phenotypic and genetic patterns in Pyrenean oaks

In this new post, Thomas Caignard, post-doc at the University of Bordeaux, presents his latest paper ‘Counter-gradient variation of reproductive effort in a widely distributed temperate oak’, discusses the relevance of the rarely found ‘counter-gradients’ and talks about the multi-disciplinary approach is currently using. About the paper Our paper aims to study the phenotypic and genetic variability of one specific life history traits in trees: … Continue reading Thomas Caignard: opposite phenotypic and genetic patterns in Pyrenean oaks

Stephanie Schmiege: leaf morphology impacts respiration in conifers

In this new post, Stephanie C. Schmiege from Columbia University (New York) presents her work on the physiological differences between flat and needle-leaved conifers, how temperature influences plants respiration mechanisms and the big opportunity she had working in tropical forests. I can think of nothing more inspiring than a grove of majestic pines or hemlocks dancing in the wind.  For as long as I can … Continue reading Stephanie Schmiege: leaf morphology impacts respiration in conifers

Xavier Morin: Finally seeing the forest for the trees? – A model to predict short term functioning and composition of forests

In this post Xavier Morin, Researcher at CEFE, CNRS, University of Montpellier, presents novel perspectives on forest gap models, highlights the complexity of ecological systems and remembers the path that lead him to being a forest scientist. About the paper Forest gap models, the first of which were developed almost 50 years ago, simulate forest dynamics (tree recruitment, growth and death) according to biotic interactions … Continue reading Xavier Morin: Finally seeing the forest for the trees? – A model to predict short term functioning and composition of forests

Rosella Guerrieri: equal but not equal, new vs long-established forests in Northeaster Spain

Rossella Guerrieri from the University of Bologne, presents her latest study ‘Land-use legacies influence tree water-use efficiency and nitrogen dynamics in recently established European forests’, discusses the importance of long-term effects of global change and provides some advices for anyone following a research career. About the paper Spontaneous forest regrowth is naturally occurring in several areas of the world promoted by on-going global changes, which … Continue reading Rosella Guerrieri: equal but not equal, new vs long-established forests in Northeaster Spain

Michael Eisenring: Within-crown heterogeneity can affect herbivore performance in tree canopies

Dr. Michael Eisenring presents his work at University of Wisconsin titled “Spatial, genetic and biotic factors shape within‐crown leaf trait variation and herbivore performance in a foundation tree species”. He discusses the importance of sub-individual trait variation and how overcoming his fear to heights was worth it.

Charlotte Poeydebat: Effects of tree diversity on forest resistance to insect herbivores

Charlotte Poeydebat, postdoc at University of Bordeaux, presents her work “Climate affects neighbour‐induced changes in leaf chemical defences and tree diversity–herbivory relationships”, discusses the importance of research networks to address general questions in ecology and share her passion for ecosystems research.
