Shifting plant investment strategies along climatic gradients drive ecosystem carbon cycling in alpine grasslands

Inge Althuizen, Norwegian Research Center AS (NORCE), discusses her article: Climate-induced shifts in plant investment strategies regulate ecosystem carbon cycling across alpine grasslands Alpine ecosystems provide a diversity of ecosystem services, including carbon storage. These cold ecosystems and carbon stored in them are particularly sensitive to climate change. But what are the mechanisms underlying carbon…

It is not just how many species are lost, but which ones disappear first

Shun Nonaka, Yokohama National University in Japan, discusses his article: Non-random species loss weakens functional diversity and species asynchrony, destabilizing grassland communities Why does the order of species loss matter? When we think about biodiversity loss, we often ask a simple question: how many species are disappearing? This is important, but it is not the…

Drought and nitrogen addition: How they jointly shape interactions among plant, arthropod, and soil nematode functional groups in temperate grasslands

Feixue Yu, Inner Mongolia University, discusses her article: Nitrogen addition weakens drought-driven coupling between plant, arthropod, and soil nematode functional groups The concurrent increase in drought and atmospheric nitrogen deposition has profoundly impacted multitrophic biodiversity and ecosystem functioning in grasslands. Nitrogen enrichment is frequently assumed to alleviate drought stress by stimulating plant growth, but this…

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.…

Cows, chemistry, and the hidden architecture of grassland stability

Baoshuang Hu and Wei Sun, Key Laboratory of Vegetation Ecology of the Ministry of Education, Jilin Songnen Grassland Ecosystem National Observation and Research Station, Northeast Normal University, discuss their article: Beyond species richness: grazing and fertilization shape temperate grassland stability through distinct stabilizing effects Imagine a vast, windswept grassland. To the casual observer, it might…

How Leaf Traits Help Us Understand the Future of Grasslands

Kuo Sun and Zhenzhu Xu, Institute of Botany of the Chinese Academy of Sciences, discuss their article: Global coordination and trade-off of grassland species traits and climatic drivers Grasslands stretch across vast parts of the world — from the wide prairies of North America to Africa’s savannas and the steppes of Asia. These landscapes are…

Woody plant encroachment in forest-grassland mosaics: How do woody plant functional traits change above and below-ground?

Raissa Jardim, Federal University of Paraná, Brazil, describes her article: Unveiling above- and below-ground ecological strategies that underlie woody plant encroachment in grasslands, in both English and Portuguese. Woody plant encroachment in forest-grassland mosaics Forests and grasslands aren’t always neatly separated ecosystems. In many places they coexist side by side, creating beautiful but complex mosaics…

How does camelid intensity influence the diversity and stability of Andean grasslands?

Ana Patricia Sandoval-Calderon and Yann Hautier, Utrecht University, discuss their article: Andean grassland stability across spatial scales increases with camelid grazing intensity despite biotic homogenization Nestled high in the Andes, a vibrant yet fragile ecosystem thrives under the watchful gaze of camelids. These ancient grasslands have been shaped over centuries by the grazing habits of…

Entangled? How to resolve feedbacks between diversity and productivity in natural systems

Karl Andraczek (@KarlAndraczek), from the German Centre for Integrative Biodiversity Research (iDiv) Halle-Jena-Leipzig, discusses his article: Weak reciprocal relationships between productivity and plant biodiversity in managed grasslands Setting The Scene Global change impacts both plant diversity and ecosystem functioning with detrimental consequences for nature’s contributions to people. Predicting these consequences has emerged as a focal…
