Hotter drought and trade‐off between fast and slow growth strategies as major drivers of tree‐ring growth variability of global conifers

Journal of Ecology, Journal Year: 2024, Volume and Issue: 112(5), P. 1123 - 1139

Abstract Temporal growth variability is an important indicator of ecosystem function under climate change. However, we still lack a unified understanding how conditions, change (trends and variability), nitrogen (N) deposition, functional traits stand factors together affect radial variability. Using global conifer tree‐ring records (123 species from 1780 sites) during 1970–2010 to calculate variability, assessed abiotic directly indirectly via with boosted regression tree structural equation models, examined the differences among continents (North America, Asia Europe). We found: (a) was mainly affected by warm‐induced drought increased at lower latitudes. Climate warming in winter could decrease but this effect far not enough offset threat hotter drought; (b) there existed trade‐off between fast‐ slow‐growing (drought tolerance) strategies for species, traits. Contrary common conjecture, higher tolerance revealed due their occupation more xeric sites, may also because investment leads less remaining growth; (c) older trees conservative strategy, while large scales, taller showed occupying productive sites; (d) moderate N deposition reduce leading conifers adopt fast‐growing strategy (e.g. Asia), long‐term excessive led North America Synthesis . Our results suggest that coniferous forests water‐limited regions should be vulnerable drought, ‘fast–slow’ key regulating effects various on stability. Moreover, future will severely threaten growth, especially old

Climate anomalies and neighbourhood crowding interact in shaping tree growth in old‐growth and selectively logged tropical forests

Journal of Ecology, Journal Year: 2024, Volume and Issue: 112(3), P. 590 - 612

Abstract Climate extremes and biotic interactions at the neighbourhood scale affect tropical forest dynamics with long‐term consequences for biodiversity, global carbon cycling climate change mitigation. However, disturbance may crowding intensity, thus relative contribution of on tree growth, thereby influencing resistance resilience to change. Here, we aim evaluate separate interactive effects neighbours growth in old‐growth disturbed forests. We used 30 years measurements over 300 species from 15 plots French Guiana investigate anomalies (in solar radiation, maximum temperature, vapour pressure deficit climatic water deficit) individual growth. Contrasting selectively logged forests, also examined how history affects sensitivity neighbours. Finally, most abundant 100 species, evaluated role 12 functional traits pertaining relations, light use mediating anomalies, their interactions. tied heat drought stress independently reduced showed positive which attenuated Their were stronger than undisturbed Fast‐growing (i.e. higher intrinsic rates) more forests sensitive crowding.

Furthermore, capture neighbours, better representing leading dimensions strategies offers a promising way towards understanding underlying ecological mechanisms govern dynamics.

Global patterns of tree wood density

Global Change Biology, Journal Year: 2024, Volume and Issue: 30(3)

Published: March 1, 2024

Wood density is a fundamental property related to tree biomechanics and hydraulic function while playing crucial role in assessing vegetation carbon stocks by linking volumetric retrieval mass estimate. This study provides high-resolution map of the global distribution wood at 0.01° (~1 km) spatial resolution, derived from four decision trees machine learning models using database 28,822 tree-level measurements. An ensemble top-performing combined with eight cross-validation strategies shows great consistency, providing patterns pronounced heterogeneity. The pattern lower values northern northwestern Europe, Canadian forest regions slightly higher Siberia forests, western United States, southern China. In contrast, tropical regions, especially wet areas, exhibit high density. Climatic predictors explain 49%-63% variations, followed characteristics (25%-31%) edaphic properties (11%-16%). Notably, leaf type (evergreen vs. deciduous) habit (broadleaved needleleaved) are most dominant individual features among all selected predictive covariates. tends be for angiosperm broadleaf compared gymnosperm needleleaf trees, particularly evergreen species. distributions categorized types have good agreement observed quantifying can help improve accurate predictions stocks, deeper insights into ecosystem functioning cycling such as vulnerability thermal stresses context future climate change.

Declining tree growth resilience mediates subsequent forest mortality in theUSMountain West

Abstract Climate change‐triggered forest die‐off is an increasing threat to global forests and carbon sequestration but remains extremely challenging predict. Tree growth resilience metrics have been proposed as measurable proxies of tree susceptibility mortality.
