Juan G. Navedo, Auteur ; Steffen Hahn, Auteur ; Manuel Parejo, Auteur ; José M. Abad-Gómez, Auteur ; Jorge S. Gutiérrez, Auteur ; Auxiliadora Villegas, Auteur ; Juan M. Sánchez-Guzmán, Auteur ; José A. Masero, AuteurWaterbirds can reallocate a considerable amount of nutrients within agricultural fields and between agriculture sites and wetlands. However their effects on biogeochemical cycles have rarely been quantified. We estimated bird numbers, diet (from[...]

Erick González-Medina, Auteur ; José Alfredo Castillo-Guerrero, Auteur ; Francisco Santiago-Quesada, Auteur ; Auxiliadora Villegas, Auteur ; José A. Masero, Auteur ; Juan M. Sánchez-Guzmán, Auteur ; Guillermo Fernández, AuteurParental care in long-lived bird species involves a trade-off between the benefits of increasing the effort expended on current offspring and the costs that this represents for future reproductive output. Under regimes of high environmental vari[...]
Article
Juan G. Navedo, Auteur ; José A. Masero, Auteur ; Otto Overdijk, Auteur ; German Orizaola, Auteur ; Juan M. Sánchez-Guzmán, AuteurUnderstanding the factors driving departure decisions from stopover sites is critical when predicting the dynamics of bird migration. We investigated the interactive effects of wind, tidal characteristics, and precipitation on the departure deci[...]
Article
José A. Masero, Auteur ; Sora M. Estrella, Auteur ; Juan M. Sánchez-Guzmán, AuteurThe foraging behaviour of typical plovers is highly stereotyped, and short-billed plovers all forage visually in a run-stop-search manner. To date, the use of a sandpiper-like foraging method by typical plovers is considered anecdotal in non-bre[...]

Ricardo J. Lopes, Auteur ; José A. Alves, Auteur ; Jennifer A. Gill, Auteur ; Tomas G. Gunnarsson, Auteur ; Jos C. E. W. Hooijmeijer, Auteur ; Pedro M. Lourenço, Auteur ; José A. Masero, Auteur ; Theunis Piersma, Auteur ; Peter M. Potts, Auteur ; Bruno Rabacal, Auteur ; Sandra Reis, Auteur ; Juan M. Sánchez-Guzmán, Auteur ; Francisco Santiago-Quesada, Auteur ; Auxiliadora Villegas, AuteurResolving the migratory connectivity (identifying non-breeding grounds) of migrating bird populations that are morphologically similar is crucial for an understanding of their population dynamics and ultimately their conservation. Such is the ca[...]
Article
Noelia Albano, Auteur ; José A. Masero, Auteur ; Juan M. Sánchez-Guzmán, Auteur ; Auxiliadora Villegas, Auteur ; Francisco Santiago-Quesada, AuteurDespite the extensive literature on energy assimilation efficiency in birds, only a few studies have dealt specifically with offspring, and to our knowledge there is no information on macronutrient assimilation efficiencies during the growth per[...]

Juan G. Navedo, Auteur ; José A. Masero, Auteur ; Juan M. Sánchez-Guzmán, Auteur ; José M. Abad-Gómez, Auteur ; Jorge S. Gutiérrez, Auteur ; Esther G. Sanson, Auteur ; Auxiliadora Villegas, Auteur ; Emilio Costillo, Auteur ; Casimiro Corbacho, Auteur ; Ricardo Moran, AuteurMany migratory waterbird populations are in decline and loss of natural wetlands is one of the main causes. However, some species may respond positively to artificial wetland recreation. In Extremadura (south-west Europe), several large reservoi[...]
Article
Juan G. Navedo, Auteur ; German Orizaola, Auteur ; José A. Masero, Auteur ; Otto Overdijk, Auteur ; Juan M. Sánchez-Guzmán, AuteurLong-distance migration is widespread among birds, connecting breeding and wintering areas through a set of stopover localities where individuals refuel and/or rest. The extent of the stopover is critical in determining the migratory strategy of[...]

José A. Masero, Auteur ; Francisco Santiago-Quesada, Auteur ; Juan M. Sánchez-Guzmán, Auteur ; Auxiliadora Villegas, Auteur ; José M. Abad-Gómez, Auteur ; Ricardo J. Lopes, Auteur ; Vitor Encarnacao, Auteur ; Casimiro Corbacho, Auteur ; Ricardo Moran, AuteurRice fields provide functional wetlands for declining shorebirds and other waterbirds around the world, but fundamental aspects of their stopover ecology in rice fields remain unknown. We estimated the length of stay of Black-tailed Godwits Limo[...]
Article
Jorge S. Gutiérrez, Auteur ; José A. Masero, Auteur ; José M. Abad-Gómez, Auteur ; Auxiliadora Villegas, Auteur ; Juan M. Sánchez-Guzmán, AuteurInvestment in immunity is commonly viewed as an energetically costly activity in birds. Although several studies have focused on the energy cost of mounting an immune response and its concomitant physiological trade-offs, nothing is known about [...]

José M. Abad-Gómez, Auteur ; José A. Masero, Auteur ; Auxiliadora Villegas, Auteur ; Noelia Albano, Auteur ; Jorge S. Gutiérrez, Auteur ; Juan M. Sánchez-Guzmán, AuteurThere is a growing body of evidence that maternal antibodies transferred to offspring have potential implications in the evolutionary ecology of birds. This transfer of maternal antibodies is a potentially flexible mechanism of non-genetic inher[...]

Auxiliadora Villegas, Auteur ; José A. Masero, Auteur ; Casimiro Corbacho, Auteur ; Jorge S. Gutiérrez, Auteur ; Noelia Albano, Auteur ; Juan M. Sánchez-Guzmán, AuteurEnvironmental conditions during early development may differentially affect male and female offspring, and the effects of this sex-environment interaction in chick performance may be exaggerated under harsh conditions. In birds, most of the curr[...]

Sara Pardal, Auteur ; José A. Alves, Auteur ; Libia Ze-Ze, Auteur ; Hugo Osorio, Auteur ; Afonso Rocha, Auteur ; Ricardo J. Lopes, Auteur ; Pete Potts, Auteur ; Fatima Amaro, Auteur ; Francisco Santiago-Quesada, Auteur ; Juan M. Sánchez-Guzmán, Auteur ; Jose Masero, Auteur ; Maria J. Alves, Auteur ; Javier Pérez-Tris, Auteur ; Jaime A. Ramos, Auteur ; Luisa Mendes, AuteurMigratory shorebirds are exposed to a wide range of pathogens along their migratory flyways, but their capacity to acquire or spread pathogens beyond endemic areas is poorly known. We focused on the spillover and acquisition of mosquito-borne pa[...]
Article
Francisco Santiago-Quesada, Auteur ; Sora M. Estrella, Auteur ; Juan M. Sánchez-Guzmán, Auteur ; José A. Masero, AuteurMany migratory water birds are known to feed both during day and night outside the breeding season, but the underlying factors and mechanisms determining this foraging pattern are poorly understood. We addressed this topic by comparing both diur[...]
