Climate warming doesn’t feel the same for everyone: The contrasted responses of tree saplings to global warming.

Benjamin Roux, University of Bordeaux in France, discusses his article: Tree canopy shapes the survival of oak and beech saplings during the regeneration stage along an elevation-driven temperature gradient The challenges of heatwaves for forest ecosystems As western Europe experiences yet another heatwave, most of the public discussion focuses on how human societies can adapt…

Integrating multiple hypotheses to understand grassland drought resistance

Diana Bertuol Garcia, University of Victoria, discusses her article: Long-term aridity shapes grassland drought resistance and modulates the roles of plant diversity and functional composition As ecologists, we often ask how ecosystems cope with change. This question now feels more urgent than ever. Around the world, ecosystems are facing habitat loss, overexploitation, invasive species, rising…

Subordinate grasses invest more underground during drought — and it makes all the difference

Alberto Canarini (University of Bologna, Italy), Pierre Mariotte (Agroscope, Switzerland), Yolima Carrillo (Western Sydney University, Australia), Raúl Ochoa-Hueso (University of Cádiz, Spain), and Barbara Drigo (Adelaide University and CRC SAAFE, Australia) discuss their article: Enhanced belowground functioning is associated with higher plant resistance against drought: implications for ecosystem functions A long-standing puzzle in grassland ecology…

Mass outweighs diversity: Dominant species mitigate grassland multifunctionality during drought in Inner Mongolia

Jiaqi Chen and Wentao Luo, Institute of Applied Ecology of the Chinese Academy of Sciences, discuss their article: Dominant species determine drought effects on grassland multifunctionality The increasing frequency of extreme drought events poses a severe threat to grassland ecosystem multifunctionality—a metric aggregating multiple ecosystem functions. However, the ecological mechanisms driving these impacts remain contentious.…

How do past disturbances shape tree growth?

Yihong Zhu, University of California, Berkeley, discusses her article: Legacy effects under an emerging novel disturbance regime: A memory-based framework to quantify tree growth responses Emergent novel disturbance regime Moderate-severity disturbances, such as drought, pathogen irruptions, and prescribed fire, may not cause widespread tree mortality, but can leave lingering impacts on surviving trees. Such disturbances…

Two grasses, two pathways: How plant strategies shape drought-microbe responses under global change

Gang Yang and Zuzana Münzbergová, Charles University in Prague, discuss their article: Contrasting drought responses in two grassland plant-microbe systems under climate change Drought is becoming more frequent and intense under global change, but plant responses vary widely. Some species are adapted to tolerate stress, while others perform well only when resources are abundant. Because…

Seedlings in a hotter, drier, CO₂-rich world: How do they cope?

María Natalia Umaña and Inés Ibañez, University of Michigan, discuss their article: How do drought and elevated temperatures influence CO2 fertilization effects on tree seedling performance? A global meta-analysis Climate change is not happening one thing at a time. In forests across the globe, seedlings are already experiencing a mix of higher atmospheric CO₂, rising…

How Does Drought Reshape Nitrogen Cycling in Subtropical Evergreen Broad-Leaved Forests? Insights from Zhejiang Tiantong Station

Songbo Tang, Jianyang Xia, and Liming Yan, East China Normal University, discusses their article: Long-term drought triggers contrasting responses of foliar stable nitrogen isotopes and soil available nitrogen in a subtropical forest Introduction: The Hidden Link Between Drought and Nitrogen Dynamics As climate change intensifies, drought events increasingly threaten the functionality of global forest ecosystems.…

Longer growing seasons don’t mean more growth: How seasonal climates shape tree wood growth in the southern Altai Mountains

Wenjin Wang, Zhejiang University in China, discusses their article: Seasonal climate variations drive decoupling between the duration and amount of xylem growth along a hydrothermal gradient in the southern Altai Mountains Climate change is transforming forests across the world. A key question many ecologists and forest managers are asking is: will warmer temperatures lead to…
