Quantifying the Earth’s forest above-ground biomass (AGB) is indispensable for effective climate action and developing forest policy. Yet, current allometric scaling models (ASMs) to estimate AGB suffer several...

Drying out defenses: drought reduces tree defense system
Drought stress is becoming increasingly common with climate change, with negative impacts on tree growth and survival. The mechanisms of drought mortality in trees are often attributed to carbon starvation or hydraulic...

Evolution and function of Scots pine aminopropyltransferases
Vuosku and colleagues find an evolutionarily old gymnosperm, Scots pine, has a bifunctional SPDS able to produce both Spd and Spm, while angiosperms seem to depend on separate enzymes in Spd and Spm biosynthesis.
Cold-induced forest dieback of rear-edge tree populations
Although extreme climatic events such as drought are known to modify forest dynamics by triggering tree dieback, the impact of extreme cold events, especially at the low-latitude margin (‘rear edge’) of species...
Freezing-related CO2 bursts reduce winter embolism
Results indicate that not all gases dissolved in the xylem sap are trapped within the ice in the stem of Scots pine and Norway spruce, during freezing.
Duration of shoot elongation in Scots pine
A study of lateral shoot growth in Scots pine over 7 years finds that daily maximum growth rate correlates positively with growth duration.
Carbon budgets in deciduous and evergreen treeline species
A study of deciduous–evergreen mixed-species forests shows that both foliar types are sink-limited when faced with decreasing temperatures.
Plants on the prowl
Plants are not noted for their dynamic lifestyles. Indeed, rooted in the soil as they tend to be, they are usually written off as little more than ‘stick in the muds’. But their sedentary lifestyle is not always so...
