Abundance of Northern Hemisphere tree species declines in the warm and arid regions of their climatic niches

The paper quantifies tree species abundance declines in their climatic niches across Northern Hemisphere forests, finding shifts toward colder and wetter regions after accounting for stand development.

Beyond mean fitness: demographic stochasticity and resilience matter at tree species climatic edges

This study shows that demographic stochasticity and recovery capacity, not just mean fitness, influence tree species' distribution edges under climate change.

Occurrence but not intensity of mortality rises towards the climatic trailing edge of tree species ranges in European forests.

The paper examines tree mortality patterns across Europe, finding higher occurrence near the climatic trailing edge but uniform intensity distribution across species ranges.

Drivers of large-scale spatial demographic variation in a perennial plant

This study identifies environmental drivers affecting population dynamics of Actaea spicata across Sweden, finding that survival and growth factors most influence population growth rate.

Tree demographic performance of European tree species at their hot and cold edges.

This study examines demographic performance of European tree species at their hot and cold edges, finding differing constraints on growth, survival, and lifespan.

Similar patterns of background mortality across Europe are mostly driven by drought in European beech and a combination of drought and competition in Scots pine.

The paper examines how drought and competition influence mortality in European beech and Scots pine across Europe, finding drought drives beech mortality while competition drives Scots pine mortality.
