However, it remains unknown how increasing aridity and livestock grazing pressure—two major drivers of global change4,5,6—shape the trait covariation that underlies plant phenotypic diversity1,7. Here we assessed how covariation among 20 chemical and morphological traits responds to aridity and grazing pressure within global drylands. Our analysis involved 133,769 trait measurements spanning 1,347 observations of 301 perennial plant species surveyed across 326 plots from 6 continents. Crossing an aridity threshold of approximately 0.7 (close to the transition between semi-arid and arid zones) led to an unexpected 88% increase in trait diversity. This threshold appeared in the presence of grazers, and moved toward lower aridity levels with increasing grazing pressure. Moreover, 57% of observed trait diversity occurred only in the most arid and grazed drylands, highlighting the phenotypic uniqueness of these extreme environments. Our work indicates that drylands act as a global reservoir of plant phenotypic diversity and challenge the pervasive view that harsh environmental conditions reduce plant trait diversity8,9,10. They also highlight that many alternative strategies may enable plants to cope with increases in environmental stress induced by climate change and land-use intensification. 000144618 540__ $$9info:eu-repo/semantics/openAccess$$aAll rights reserved$$uhttp://www.europeana.eu/rights/rr-f/ 000144618 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/acceptedVersion 000144618 700__ $$aMaestre, Fernando T. 000144618 700__ $$aLiancourt, Pierre 000144618 700__ $$aBerdugo, Miguel 000144618 700__ $$aMartin, Raphaël 000144618 700__ $$aGozalo, Beatriz 000144618 700__ $$aOchoa, Victoria 000144618 700__ $$aDelgado-Baquerizo, Manuel 000144618 700__ $$aMaire, Vincent 000144618 700__ $$aSaiz, Hugo$$uUniversidad de Zaragoza 000144618 700__ $$aSoliveres, Santiago 000144618 700__ $$aValencia, Enrique 000144618 700__ $$aEldridge, David J. 000144618 700__ $$aGuirado, Emilio 000144618 700__ $$aJabot, Franck 000144618 700__ $$aAsensio, Sergio 000144618 700__ $$aGaitán, Juan J. 000144618 700__ $$aGarcía-Gómez, Miguel 000144618 700__ $$aMartínez, Paloma 000144618 700__ $$aMartínez-Valderrama, Jaime 000144618 700__ $$aMendoza, Betty J. 000144618 700__ $$aMoreno-Jiménez, Eduardo 000144618 700__ $$aPescador, David S. 000144618 700__ $$aPlaza, César 000144618 700__ $$aPijuan, Ivan Santaolaria 000144618 700__ $$aAbedi, Mehdi 000144618 700__ $$aAhumada, Rodrigo J. 000144618 700__ $$aAmghar, Fateh 000144618 700__ $$aArroyo, Antonio I. 000144618 700__ $$aBahalkeh, Khadijeh 000144618 700__ $$aBailey, Lydia 000144618 700__ $$aBen Salem, Farah 000144618 700__ $$aBlaum, Niels 000144618 700__ $$aBoldgiv, Bazartseren 000144618 700__ $$aBowker, Matthew A. 000144618 700__ $$aBranquinho, Cristina 000144618 700__ $$avan den Brink, Liesbeth 000144618 700__ $$aBu, Chongfeng 000144618 700__ $$aCanessa, Rafaella 000144618 700__ $$aCastillo-Monroy, Andrea del P. 000144618 700__ $$aCastro, Helena 000144618 700__ $$aCastro, Patricio 000144618 700__ $$aChibani, Roukaya 000144618 700__ $$aConceição, Abel Augusto 000144618 700__ $$aDarrouzet-Nardi, Anthony 000144618 700__ $$aDavila, Yvonne C. 000144618 700__ $$aDeák, Balázs 000144618 700__ $$aDonoso, David A. 000144618 700__ $$aDurán, Jorge 000144618 700__ $$aEspinosa, Carlos 000144618 700__ $$aFajardo, Alex 000144618 700__ $$aFarzam, Mohammad 000144618 700__ $$aFerrante, Daniela 000144618 700__ $$aFranzese, Jorgelina 000144618 700__ $$aFraser, Lauchlan 000144618 700__ $$aGonzalez, Sofía 000144618 700__ $$aGusman-Montalvan, Elizabeth 000144618 700__ $$aHernández-Hernández, Rosa Mary 000144618 700__ $$aHölzel, Norbert 000144618 700__ $$aHuber-Sannwald, Elisabeth 000144618 700__ $$aJadan, Oswaldo 000144618 700__ $$aJeltsch, Florian 000144618 700__ $$aJentsch, Anke 000144618 700__ $$aJu, Mengchen 000144618 700__ $$aKaseke, Kudzai F. 000144618 700__ $$aKindermann, Liana 000144618 700__ $$ale Roux, Peter 000144618 700__ $$aLinstädter, Anja 000144618 700__ $$aLouw, Michelle A. 000144618 700__ $$aMabaso, Mancha 000144618 700__ $$aMaggs-Kölling, Gillian 000144618 700__ $$aMakhalanyane, Thulani P. 000144618 700__ $$aIssa, Oumarou Malam 000144618 700__ $$aManzaneda, Antonio J. 000144618 700__ $$aMarais, Eugene 000144618 700__ $$aMargerie, Pierre 000144618 700__ $$aHughes, Frederic Mendes 000144618 700__ $$aMesseder, João Vitor S. 000144618 700__ $$aMora, Juan P. 000144618 700__ $$aMoreno, Gerardo 000144618 700__ $$aMunson, Seth M. 000144618 700__ $$aNunes, Alice 000144618 700__ $$aOliva, Gabriel 000144618 700__ $$aOñatibia, Gaston R. 000144618 700__ $$aPeter, Guadalupe 000144618 700__ $$aPueyo, Yolanda 000144618 700__ $$aQuiroga, R.
