Unforeseen plant phenotypic diversity in a dry and grazed world
Gross, Nicolas; Maestre, Fernando T.; Liancourt, Pierre; Berdugo, Miguel; Martin, Raphaël; Gozalo, Beatriz; Ochoa, Victoria; Delgado-Baquerizo, ManuelEarth harbours an extraordinary plant phenotypic diversity1 that is at risk from ongoing global changes2,3. 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 pr...
Hotspots of biogeochemical activity linked to aridity and plant traits across g...
Eldridge, David J.; Ding, Jingyi; Dorrough, Josh; Delgado-Baquerizo, Manuel; Sala, Osvaldo; Gross, Nicolas; Le Bagousse-Pinguet, YoannPerennial plants create productive and biodiverse hotspots, known as fertile islands, beneath their canopies. These hotspots largely determine the structure and functioning of drylands worldwide. Despite their ubiquity, the factors controlling fertile islands under conditions of contrasting grazing by livestock, the most prevalent land use in drylands, remain virtually unknown. Here we evaluated the relative im...
Native species can reduce the establishment of invasive alien species if sown i...
Csákvári, Edina; Sáradi, Nóra; Berki, Boglárka; Csecserits, Anikó; Csonka, Anna Cseperke; Reis, Bruna; Török, Katalin; Valkó, Orsolya; Vörös, MártonInvasion of alien species is one of the main drivers of land degradation threatening both natural and managed ecosystems. Ecological restoration is crucial in controlling invasion to improve biotic resistance and avoid further land degradation. We investigated the possibility of controlling the establishment of invasive alien species (IAS) by native seed addition. We tested if trait similarity or increased prop...
Grazing and ecosystem service delivery in global drylands
Maestre, Fernando T.; Le Bagousse-Pinguet, Yoann; Delgado-Baquerizo, Manuel; Eldridge, David J.; Saiz, Hugo; Berdugo, Miguel; Gozalo, BeatrizGrazing represents the most extensive use of land worldwide. Yet its impacts on ecosystem services remain uncertain because pervasive interactions between grazing pressure, climate, soil properties, and biodiversity may occur but have never been addressed simultaneously. Using a standardized survey at 98 sites across six continents, we show that interactions between grazing pressure, climate, soil, and biodiver...
Fine‐grain beta diversity of Palaearctic grassland vegetation
Dembicz, Iwona; Dengler, Jürgen; Steinbauer, Manuel J.; Matthews, Thomas J.; Bartha, Sándor; Burrascano, Sabina; Chiarucci, AlessandroQUESTIONS: Which environmental factors influence fine-grain beta diversity of vegetation and do they vary among taxonomic groups? LOCATION: Palaearctic biogeographic realm. METHODS: We extracted 4,654 nested-plot series with at least four different grain sizes between 0.0001 m² and 1,024 m² from the GrassPlot database, covering a wide range of different grassland and other open habitat types. We derived extensi...
Current Wildland Fire Patterns and Challenges in Europe: A Synthesis of Nationa...
Fernandez-Anez, Nieves; Krasovskiy, Andrey; Müller, Mortimer; Vacik, Harald; Baetens, Jan; Hukić, Emira; Kapovic Solomun, Marijana; Atanassova, IrenaChanges in climate, land use, and land management impact the occurrence and severity of wildland fires in many parts of the world. This is particularly evident in Europe, where ongoing changes in land use have strongly modified fire patterns over the last decades. Although satellite data by the European Forest Fire Information System provide large-scale wildland fire statistics across European countries, there ...

Species–area relationships in continuous vegetation : Evidence from Palaearctic...
Dengler, Jürgen; Matthews, Thomas J.; Steinbauer, Manuel J.; Wolfrum, Sebastian; Boch, Steffen; Chiarucci, Alessandro; Conradi, Timo; Dembicz, IwonaAIM: Species-area relationships (SARs) are fundamental scaling laws in ecology although their shape is still disputed. At larger areas, power laws best represent SARs. Yet, it remains unclear whether SARs follow other shapes at finer spatial grains in continuous vegetation. We asked which function describes SARs best at small grains and explored how sampling methodology or the environment influence SAR shape. L...
