Drivers of woody dominance across global drylands
Biancari, Lucio; Aguiar, Martín R.; Eldridge, David J.; Oñatibia, Gastón R.; Le Bagousse-Pinguet, Yoann; Saiz, Hugo; Gross, Nicolas; Austin, Amy T.Increases in the abundance of woody species have been reported to affect the provisioning of ecosystem services in drylands worldwide. However, it is virtually unknown how multiple biotic and abiotic drivers, such as climate, grazing, and fire, interact to determine woody dominance across global drylands. We conducted a standardized field survey in 304 plots across 25 countries to assess how climatic features, ...
Distribution of alien tetrapods in the Iberian Peninsula
Ascensão, Fernando; D'Amico, Marcello; Martins, Ricardo C.; Rebelo, Rui; Barbosa, A. Márcia; Bencatel, Joana; Barrientos, Rafael; Abellán, PedroWe present a dataset that assembles occurrence records of alien tetrapods (amphibians, reptiles, birds and mammals) in the Iberian Peninsula, a coherent biogeographically unit where introductions of alien species have occurred for millennia. These data have important potential applications for ecological research and management, including the assessment of invasion risks, formulation of preventive and managemen...

Network structure of vertebrate scavenger assemblages at the global scale: driv...
Sebastián‐González, Esther; Morales‐Reyes, Zebensui; Botella, Francisco; Naves‐Alegre, Lara; Pérez‐García, Juan M.; Mateo-Tomás, PatriciaThe organization of ecological assemblages has important implications for ecosystem functioning, but little is known about how scavenger communities organize at the global scale. Here, we test four hypotheses on the factors affecting the network structure of terrestrial vertebrate scavenger assemblages and its implications on ecosystem functioning. We expect scavenger assemblages to be more nested (i.e. structu...
Drivers of compositional dissimilarity for native and alien birds: the relative...
Ascensão, Fernando; Latombe, Guillaume; Anadón, José D.; Abellán, Pedro; Cardador, Laura; Carrete, Martina; Tella, José L.; Capinha, CésarWe assessed the relative importance of human activity and environmental suitability as drivers of compositional dissimilarity of alien birds for 65 of the most populous cities of the Iberian Peninsula. We examined how these drivers relate to Zeta diversity (ζ) for alien Passeriformes and Psittaciformes. We performed the analysis using multiple orders of ζ, which provides insight on the role played by rare and c...
