Abstract

Forests in tectonically active regions are disturbed by earthquakes. Besides direct injuries to trees, earthquakes also induce stand-wide changes in hydrological conditions, whose effects on long-term forest growth and resilience remain unknown. Here we establish spatio-temporal links between global tree-ring width series and earthquakes after 1900, disentangle seismic signals from climate-induced variations in ring width series, test growth changes using superposed epoch analysis and quantify post-earthquake resilience shifts along environmental gradients in seven regions around the world. We found sites with enhanced resilience locate in relatively dry areas of temperate regions, where the response of tree growth to growing-season precipitation also increased after earthquakes. Our results provide evidence that earthquake-induced soil cracks and fractures increased precipitation infiltration to deeper soil layers and enhanced the use of water and nutrients by trees. In contrast, reduced post-earthquake resilience in regions with abundant precipitation can be explained by increased soil erosion and nutrient leaching. We conclude that seismic disturbances cause decadal-scale shifts in forest resilience under specific environmental conditions, disentangling complex interactions between lithosphere, biosphere and atmosphere. These findings can contribute to a better understanding of how the Earth system functions.

Abstract

Climatic warming alters the onset, duration and cessation of the vegetative season. While previous studies have shown a tight link between thermal conditions and leaf phenology, less is known about the impacts of phenological changes on tree growth. Here, we assessed the relationships between the start of the thermal growing season and tree growth across the extratropical Northern Hemisphere using 3,451 tree-ring chronologies and daily climatic data for 1948–2014. An earlier start of the thermal growing season promoted growth in regions with high ratios of precipitation to temperature but limited growth in cold–dry regions. Path analyses indicated that an earlier start of the thermal growing season enhanced growth primarily by alleviating thermal limitations on wood formation in boreal forests and by lengthening the period of growth in temperate and Mediterranean forests. Semi-arid and dry subalpine forests, however, did not benefit from an earlier onset of growth and a longer growing season, presumably due to associated water loss and/or more frequent early spring frosts. These emergent patterns of how climatic impacts on wood phenology affect tree growth at regional to hemispheric scales hint at how future phenological changes may affect the carbon sequestration capacity of extratropical forest ecosystems.

Abstract

Ecological theory is built on trade-offs, where trait differences among species evolved as adaptations to different environments. Trade-offs are often assumed to be bidirectional, where opposite ends of a gradient in trait values confer advantages in different environments. However, unidirectional benefits could be widespread if extreme trait values confer advantages at one end of an environmental gradient, whereas a wide range of trait values are equally beneficial at the other end. Here, we show that root traits explain species occurrences along broad gradients of temperature and water availability, but model predictions only resembled trade-offs in two out of 24 models. Forest species with low specific root length and high root tissue density (RTD) were more likely to occur in warm climates but species with high specific root length and low RTD were more likely to occur in cold climates. Unidirectional benefits were more prevalent than trade-offs: for example, species with large-diameter roots and high RTD were more commonly associated with dry climates, but species with the opposite trait values were not associated with wet climates. Directional selection for traits consistently occurred in cold or dry climates, whereas a diversity of root trait values were equally viable in warm or wet climates. Explicit integration of unidirectional benefits into ecological theory is needed to advance our understanding of the consequences of trait variation on species responses to environmental change.
