Article
Adrián Talavera, Auteur ; José Luis Tellería, AuteurWe tested whether microhabitat use affects dispersal and population differentiation in forest birds of the southwestern Palaearctic, a link previously suggested in Neotropical birds. To approach this, the number of subspecies within 32 species w[...]
Article
Mediterranean mountains are biodiversity hotspots where northern species occur surrounded by drier and warmer lowlands. In this context, global warming is pushing these species to higher elevations. This paper assesses whether forest birds have [...]
Article
Guillermo Fandos, Auteur ; José Luis Tellería, AuteurBecause migrant birds occur in different parts of the world in different seasons, their numbers may be limited by the size of the smallest area they inhabit during the year. In addition, restricted ranges make populations more susceptible to loc[...]
Article
Iván De la Hera, Auteur ; Javier Pérez-Tris, Auteur ; José Luis Tellería, AuteurThere is increasing evidence of adaptive preferential investment during moult in those feather tracts that are more advantageous for fitness. In this study, we assessed whether, after the manual removal of two functionally different flight feath[...]

Article
Iván De la Hera, Auteur ; Jose A. Diaz, Auteur ; Javier Pérez-Tris, Auteur ; José Luis Tellería, AuteurBirds moult to maintain plumage function through life, but the factors that determine moult duration are poorly understood. In temperate areas, variation in moult duration could be largely associated with between-species differences in migratory[...]
Article
José Luis Tellería, Auteur ; Javier Pérez-Tris, AuteurIf resource availability shapes population distribution, changes in resource abundance should cause parallel changes in population numbers. However, tracking ability may be disrupted by different environmental and behavioural factors that act at[...]
Article
Iván De la Hera, Auteur ; Javier Pérez-Tris, Auteur ; José Luis Tellería, AuteurMoult is a costly but necessary process in avian life, which displays two main temporal patterns within the annual cycle of birds (summer and winter moult). Timing of moult can affect its duration and consequently the amount of material invested[...]
Article
Iván De la Hera, Auteur ; Anders Hedenstroem, Auteur ; Javier Pérez-Tris, Auteur ; José Luis Tellería, AuteurMigration causes temporal and energetic constraints during plumage development, which can compromise feather structure and function. In turn, given the importance of a good quality of flight feathers in migratory movements, selection may have fa[...]
