The position of alpine and Arctic treelines is considered to be determined by temperature. Therefore, with climate warming these treelines are expected to move upwards in the mountains or towards the poles. However, this is not always what is observed and sometimes the treeline has … Continue reading Review: What determines the success of a tree seedling beyond the alpine treeline?

Kimberley T. Davis, Anna Sala, Philip E. Higuera This paper is part of the Special Feature: A Mechanistic Understanding of Global Change Ecology. Climate change affects forests directly, because plants require certain climate conditions to reproduce and survive. Climate change also affects forests indirectly, by influencing how often forests burn in wildfires. This indirect effect of climate change is important to understand because wildfires can … Continue reading Review: Anticipating fire‐mediated impacts of climate change using a demographic framework

Carly J. Stevens, Thomas I. David, Jonathan Storkey This paper is part of the Special Feature: A Mechanistic Understanding of Global Change Ecology. Although nitrogen is an essential nutrient for plants, they can have too much of a good thing and reactive forms of nitrogen (such as nitrogen oxides and ammonia) can be pollutants as a consequence. Levels of reactive nitrogen in the atmosphere have … Continue reading Atmospheric nitrogen deposition in terrestrial ecosystems: Its impact on plant communities and consequences across trophic levels
