Climate change is increasing the frequency and severity of short-term (~1 y) drought events—the most common duration drought—globally. Yet impact this intensification on ecosystem functioning remains poorly resolved. This due in part to widely disparate approaches ecologists have employed study drought, variation studied, differences among ecosystems vegetation, edaphic climatic attributes that can mediate impacts. To overcome these problems better identify factors modulate responses, we...
Nitrogen (N), after water, is considered the key factor limiting net primary production in drylands. However, whether vegetation N-limited depends on balance between N supply and biological demand, a relationship that remains unclear Here, we established standardized field survey across 25 countries, including 326 plots, to assess how plant limitation responds aridity global We found while availability decreased with aridity, soil δ¹⁵N—an indicator of...
Abstract Questions (1) Is the co‐dominance of grasses and shrubs a general feature Patagonian steppes? (2) At local scale, does it change with domestic grazing intensity or decadal changes in precipitation? Locations Question 1. Patagonia region southern South America. 2. Shrub–grass steppes (45°24′S, 70°17′W) subjected to different for decades. Methods We sampled vegetation estimate perennial grass shrub cover at two scales: regional local. (phytogeographical) we grazed under climates soils...
Increases in the abundance of woody species have been reported to affect provisioning ecosystem services drylands worldwide. However, it is virtually unknown how multiple biotic and abiotic drivers, such as climate, grazing, fire, interact determine dominance across global drylands. We conducted a standardized field survey 304 plots 25 countries assess climatic features, soil properties, fire dryland rangelands. Precipitation, temperature, grazing were key determinants tree shrub dominance....
In a recent Tansley Review, Holdo and Nippert (2023) provided comprehensive analysis of existing models that explain tree-grass coexistence along precipitation gradients in savannas. They proposed three key elements definitive savanna model should include predicted the upper boundary pattern tree cover based on ‘Sankaran curve’ depending soil texture. We tested this drylands using global field data (98 sites from 25 countries six continents) accounting wide range environmental conditions...
