There 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[...]texto impreso
Hera Fernández, Iván de la | Universidad Complutense de Madrid, Servicio de Publicaciones | 2009-03-03En las aves, las presiones temporales que implica la migración han conducido a una reducción de la duración del proceso de sustitución del plumaje (muda). Sin embargo, esta aceleración de la muda está asociada con la producción de plumas de meno[...]texto impreso

Tomatoni, Barbara M. ; Caglar, Ezra ; Hera Fernández, Iván de la ; Mataman, A. Christa ; Visser, Marcel E. | Wiley | 2017-06When assessing the benefits of early arrival date of migratory birds, a hidden and often ignored component of males’ fitness is the higher chance of early-arriving birds to obtain extra-pair fertilizations. Here we investigated how extra-pair pa[...]texto impreso
Visser, Marcel E. ; Gienapp, Phillip ; Husby, Arild ; Morrisey, Michael ; Hera Fernández, Iván de la ; Pulido Delgado, Francisco ; Both, Christiaan | Public Library of Sciences (PLOS) | 2015-04Climate change has differentially affected the timing of seasonal events for interacting trophic levels, and this has often led to increased selection on seasonal timing. Yet, the environmental variables driving this selection have rarely been i[...]texto impreso
Pérez Rodríguez, Antón David ; Hera Fernández, Iván de la ; Bensch, Staffan ; Pérez Tris, Javier | Elsevier | 2015-08In temperate regions, many vector-borne parasites maximise their transmission prospects by adjusting reproduction to seasonal cycles of host susceptibility and vector availability. Nevertheless, in these regions there are areas where environment[...]texto impreso
Hera Fernández, Iván de la ; Fandos Guzmán, Guillermo ; Fernández López, Javier ; Onrubia, Alejandro ; Pérez Rodríguez, Antón David ; Pérez Tris, Javier ; Tellería Jorge, José Luis | Wiley | 2018-04Mediterranean woodlands and associated shrub formations of southern Iberia are key habitats for conservation of migratory birds. In some bird species, migratory and sedentary conspecifics meet in these areas during winter, but our understanding [...]texto impreso
Fernández González, Sofía ; Pérez Rodríguez, Antón David ; Proctor, Heather C. ; Hera Fernández, Iván de la ; Pérez Tris, Javier | Cambridge University Press | 2018-01-17Obligate symbionts may be genetically structured among host individuals and among phenotypically distinct host populations. Such processes may in turn determine within-host genetic diversity of symbionts, which is relevant for understanding symb[...]texto impreso
Hera Fernández, Iván de la ; Hernández-Téllez, Irene ; Pérez Regueiro, José ; Pérez Tris, Javier ; Rojo, Francisco Javier ; Tellería Jorge, José Luis | Wiley | 2020-04-13Current avian migration patterns in temperate regions have been developed during the glacial retreat and subsequent colonization of the ice-free areas during the Holocene. This process resulted in a geographic gradient of greater seasonality as [...]texto impreso
Hera Fernández, Iván de la ; Fandos Guzmán, Guillermo ; Fernández López, Javier ; Onrubia, Alejandro ; Pérez-Rodríguez, Antón ; Pérez Tris, Javier ; Tellería Jorge, José Luis | Sociedad Española de Ornitología (SEO/BirdLife) | 2017-07Morphological methods to distinguish between avian groups of research interest (e.g. differentsexes, populations or cryptic species) need to be externally validated to ensure reliable performance across situations. In this study, we used stable [...]texto impreso
Doña, Jorge ; Potti, Jaime ; Hera Fernández, Iván de la ; Blanco, Guillermo ; Frías, Óscar ; Jovani, Roger | Wiley | 2017-081.The consequences of symbiont transmission strategies are better understood than their adaptive causes. 2.Feather mites are permanent ectosymbionts of birds assumed to be transmitted mainly vertically from parents to offspring. The transmissio[...]
