We study how local processes give rise to larger patterns, and how links between scales shape forest structure and diversity.
We are based in the Department of Plant Ecology and Evolution at Uppsala University in Sweden.

I'm delighted to be awarded an early-career researcher project grant from FORMAS! Stay tuned for exciting new directions on land-use, tropical trees, and (tree) population genetics! Very excited to collaborate with my colleague Pascal Milesi on this project!
New paper out on Puerto Rico forest dynamics led by the fantastic Naomi Schwartz: Topography and traits mediate tree performance and drought response in a tropical forest. Frontiers in Forests and Global Change.
Lots of discussion on tree planting these days. In this new paper, Forrest Fleischman leads the arguments about why the human dimension is critical to keep in mind. Pitfalls of tree planting show why we need people-centered natural climate solutions. BioScience.

November 2019: Really happy to present at the Linnean Centre for Plant Biology Annual meeting! Great to meet more plant biologists in Uppsala.
July 2019: A new Data Paper has been accepted at Ecology: "Palm community transects and soil properties in western Amazonia". This dataset has been built up by Henrik Balslev (Aarhus University) and colleagues over the past 20+ years. While parts of it have been used for numerous publications from Henrik's group, this is the first release of the full dataset, including data on soil chemistry and other characteristics. Hopefully this dataset will be a useful resource for people interested in palms and/or tropical soils. <LINK>

October 2018: Happy to say that two new papers have been accepted!
- "Effects of biotic interactions on tropical tree performance depend on abiotic conditions"(Ecology) was done in collaboration with the great collaborators Julie Messier, Richard Condit, Steve Hubbell, and Jens-Christian Svenning. <Link>
- "Soil fertility and flood regime are correlated with phylogenetic structure of Amazonian palm communities" (Annals of Botany) was a really nice chance to collaborate with Christine Bacon, Søren Faurby, and Alexander Antonelli from Gothenburg University as well as my Aarhus University and @EcoInf colleagues. <Link>
May 2018: New work out in Nature Ecology & Evolution from our amazing 2ndFor Network! This one led by Maga Gei: "Ecological success of tropical legumes across succession and rainfall gradients". <Link>.

January 2018: New work out from the Luquillo LTER led by Benedicte Bachelot: "Associations among arbuscular mycorrhizal fungi and seedlings are predicted to change with tree successional status" in Ecology <Link>.
November 2017: It's been an exciting week with three new papers accepted!!! In Uriarte et al. (Global Change Biology), we show how abiotic and biotic conditions interactively mediate climate impacts on tropical seedling survival. In Kass et al. (Methods in Ecology & Evolution), we present Wallace: a modular web-based application (available as an R package here). Finally, in Guérin et al. (Ecology and Evolution), we look at drought influences on inter-annual variation of hydraulic traits in Pinus edulis.
