The effect of climate change on avian offspring production: A global meta-analysis
Halupka, Lucyna; Arlt, Debora; Tolvanen, Jere; Millon, Alexandre; Bize, Pierre; Adamík, Peter; Albert, Pascal; Arendt, Wayne J.; Artemyev, Alexander V.Climate change affects timing of reproduction in many bird species, but few studies have investigated its influence on annual reproductive output. Here, we assess changes in the annual production of young by female breeders in 201 populations of 104 bird species (N = 745,962 clutches) covering all continents between 1970 and 2019. Overall, average offspring production has declined in recent decades, but conside...
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...
Farmer Perceptions of the Ecosystem Services Provided by Scavengers: What, Who,...
Morales-Reyes, Zebensui; Martín-López, Berta; Moleón, Marcos; Mateo-Tomás, Patricia; Botella, Francisco; Margalida, Antoni; Donázar, José A.A socioecological approach to biodiversity conservation has recently been encouraged. We examined farmer perceptions of ecosystem services provided by scavenging vertebrates in Spain through face-to-face surveys with farmers in seven large extensive livestock systems. Scavenging services (i.e., carrion consumption) was the most perceived benefit whereas the role of some scavengers as predators was the most reco...
