Article
Manuel Soler, Auteur ; Elena Macías-Sanchez, Auteur ; David Martín-Gálvez, Auteur ; Liesbeth de Neve, AuteurParent decisions about food allocation are usually based on simple time-saving rules that optimize their own fitness; however, they can sometimes vary depending on the prevailing ecological conditions both outside and inside the nest. Parent–off[...]

Liesbeth de Neve, Auteur ; Juan J. Soler, Auteur ; Magdalena Ruiz-Rodríguez, Auteur ; David Martín-Gálvez, Auteur ; Tomas Perez-Contreras, Auteur ; Manuel Soler, AuteurParasite pressure and nutrition are two of the most important factors affecting the trade-off between nestling growth and immune development. During development, energy and nutrients are often limited, and nestlings should only dedicate differen[...]

Magdalena Ruiz-Rodríguez, Auteur ; Juan J. Soler, Auteur ; Francoise S. Lucas, Auteur ; Philipp Heeb, Auteur ; Maria Jose Palacios, Auteur ; David Martín-Gálvez, Auteur ; Liesbeth de Neve, Auteur ; Tomas Perez-Contreras, Auteur ; Juan G. Martinez, Auteur ; Manuel Soler, AuteurDiversity of the gut bacterial community is of prime importance for optimal food digestion and, therefore, for nutritional condition of avian nestlings. Consequently, bacterial community should be considered as a predictor of the future survival[...]

Davy S. Bosman, Auteur ; Harry J. P. Vercruijsse, Auteur ; Eric W. M. Stienen, Auteur ; Magda Vincx, Auteur ; Liesbeth de Neve, Auteur ; Luc Lens, AuteurStudies of migration have revealed multiple trade-offs with other life-history traits that may underlie observed variation in migratory properties among ages and sexes. To assess whether, and to what extent, body size and/or sex-specific differe[...]

Greet De Coster, Auteur ; Liesbeth de Neve, Auteur ; Luc Lens, AuteurAmong the most eye-catching traits of avian eggs are their background coloration and pigmentation, consisting in many passerine birds of dark protoporphyrin spots. Although variation in protoporphyrin pigmentation among clutches has been shown t[...]

David Martín-Gálvez, Auteur ; Liesbeth de Neve, Auteur ; Tomas Perez-Contreras, Auteur ; Manuel Soler, Auteur ; Juan Gabriel Martinez, Auteur ; Juan Jose Soler, AuteurBrood parasitic nestlings usually exhibit an exaggerated begging behaviour, which is mainly attributed to reduced inclusive fitness costs since they typically share the nest with unrelated individuals. However, energetic costs also constrain beg[...]
Article
Greet De Coster, Auteur ; Liesbeth de Neve, Auteur ; Simon Verhulst, Auteur ; Luc Lens, AuteurMothers can adjust the phenotype of their offspring to the local environment through a modification of their egg investment and/or nestling provisioning. However, offspring health may be severely impaired if the conditions experienced by nestlin[...]

Tom Rosendahl Larsen, Auteur ; Graham D. Fairhurst, Auteur ; Siegrid De Baere, Auteur ; Siska Croubels, Auteur ; Wendt Muller, Auteur ; Liesbeth de Neve, Auteur ; Luc Lens, AuteurInter- and intra-clutch variation in egg corticosterone (CORT), the major glucocorticoid in birds, may provide insights into how maternal stress levels vary with the timing of breeding and with laying order. Common analytical methods (e.g. immun[...]
Article
Maria Dolores G. Lopez de Hierro, Auteur ; Liesbeth de Neve, AuteurOne of the hypotheses to explain egg colour variation in birds lays in the context of sexual selection, where egg colour may signal the female's physical condition and antioxidant capacity. We tested one of the assumptions following from this hy[...]
