What drives tree recruitment at alpine tree lines?

Valentin Graf, Senckenberg Biodiversity and Climate Research Centre in Frankfurt, discusses his article: Relative importance of range position, seed size, and genetic diversity for tree recruitment at alpine range edges Climate change is rapidly altering ecosystems, pushing many species to adapt or move to cooler environments. In mountains, this often means shifting to higher elevations,…

How New Zealand’s mangrove seedlings weather the waves: Lessons from monospecific forests

Lukas Meysick, Carl von Ossietzky Universität Oldenburg, discusses his article: Facilitation and constraint: Wave exposure and intraspecific interactions influence mangrove seedling morphology and resistance to dislodgement When mangrove forests come to mind, many people picture tropical coasts lined with diverse tree communities, sometimes consisting of more than 20 species in a single region. With this…

Seedlings in a hotter, drier, CO₂-rich world: How do they cope?

María Natalia Umaña and Inés Ibañez, University of Michigan, discuss their article: How do drought and elevated temperatures influence CO2 fertilization effects on tree seedling performance? A global meta-analysis Climate change is not happening one thing at a time. In forests across the globe, seedlings are already experiencing a mix of higher atmospheric CO₂, rising…
