Timothée Schwartz, Auteur ; Aurélien Besnard, Auteur ; Jesus M. Aviles, Auteur ; Teresa Catry, Auteur ; Andrzej Gorski, Auteur ; Orsolya Kiss, Auteur ; Deseada Parejo, Auteur ; Edmunds Račinskis, Auteur ; Laimonas Sniauksta, Auteur ; Milda Šniaukštienė, Auteur ; Otto Szekeres, Auteur ; Ines Catry, AuteurLife-history theory predicts that animals should develop adaptive trade-offs between survival and reproduction to maximize their fitness. This results in a continuum of life-history strategies among species, ranging from slow to fast paces-of-li[...]

Orsolya Kiss, Auteur ; Ines Catry, Auteur ; Jesus M. Aviles, Auteur ; Sanja Barisic, Auteur ; Tatiana Kuzmenko, Auteur ; Svilen Cheshmedzhiev, Auteur ; Ana Teresa Marques, Auteur ; Angelo Meschini, Auteur ; Timothée Schwartz, Auteur ; Béla Tokody, Auteur ; Zsolt Vegvari, AuteurWe used MaxEnt for species distribution modelling based on the reconstructed distribution map of the species. Our results suggest that during glacial periods Rollers persisted in small southern refugia, and then spread and colonized northern la[...]
Article
Mónica Expósito-Granados, Auteur ; Deseada Parejo, Auteur ; Olivier Chastel, Auteur ; Jesus M. Aviles, AuteurHuman activities are altering ecosystems and threatening the well-being of wildlife. The study of the stressful effects of human disturbances on animal distribution, physiology and behaviour can provide fundamental insights for wildlife conserva[...]
Article
Juan Rodríguez-Ruiz, Auteur ; Mónica Expósito-Granados, Auteur ; Jesus M. Aviles, Auteur ; Deseada Parejo, AuteurStudying demographic parameters and how they may influence population growth is critical to the development of meaningful conservation actions for endangered species. The European Roller Coracias garrulus has experienced a drastic decline throug[...]

Juan Rodríguez-Ruiz, Auteur ; Francois Mougeot, Auteur ; Deseada Parejo, Auteur ; Javier de La Puente, Auteur ; Ana Bermejo, Auteur ; Jesus M. Aviles, AuteurThe identification of threats to migratory species of conservation concern and the relevance of protected areas for them is often biased towards breeding areas. The European Roller Coracias garrulus is a long-distance migrant experiencing a pron[...]
Article
Magdalena Ruiz-Rodríguez, Auteur ; Manuel Martin-Vivaldi, Auteur ; Jesus M. Aviles, AuteurAnimals can engage in visual displays, which may target conspecifics, heterospecifics or both. Here we studied the function of the flamboyant crest-raising display of hoopoes Upupa epops in experiments performed with males in captivity. Males we[...]
Article
Jose J. Cuervo, Auteur ; Juan J. Soler, Auteur ; Jesus M. Aviles, Auteur ; Tomas Perez-Contreras, Auteur ; Carlos Navarro, AuteurHematocrit, the proportion of blood volume occupied by packed red blood cells, is frequently used as an estimate of phenotypic condition. Some studies in birds, however, suggest that hematocrit might not always be a good estimate of condition. W[...]
Article
Roger Jovani, Auteur ; Jesus M. Aviles, Auteur ; Francisco Rodriguez-Sanchez, AuteurMale and female European Robins Erithacus rubecula display their red breasts in year-round territorial contests. Despite the clear signalling role of the red breast, little is known about its sexual dimorphism or trends in size when Robins age. [...]
Article
Carlos Navarro, Auteur ; Tomas Perez-Contreras, Auteur ; Jesus M. Aviles, Auteur ; Kevin J. McGraw, Auteur ; Juan J. Soler, AuteurThe hypothesis that eggshell colouration is a sexually selected trait of female birds is based on the fact that biliverdin, the pigment responsible for blue-green colours of the eggshell, is a potent antioxidant and that only females with high a[...]
Article
Jesus M. Aviles, Auteur ; Deseada Parejo, AuteurVividly coloured chromatic signals play a key role in social and sexual signalling in diurnal birds, but their role is considered negligible in favour of achromatic (i.e. white, pure grey and black colourations) signals in nocturnal species. Her[...]
Article
Jesus M. Aviles, Auteur ; Elena Solis, Auteur ; Juliana Valencia, Auteur ; Carlos de la Cruz, Auteur ; Gabriele Sorci, AuteurAnimals may assess the quality of other individuals by using information that is contained in elaborate traits. We investigated the degree of sexual dimorphism in structural blue plumage coloration and the potential signal value of these traits [...]
Article
Jesus M. Aviles, Auteur ; Peter A. Bednekoff, AuteurAnimals often spend less time vigilant and more time feeding when foraging in larger groups. This group-size effect does not, however, consider if larger groups differ systematically from smaller ones: Large groups could form in different habita[...]
Article
Deseada Parejo, Auteur ; Nadia Silva, Auteur ; Etienne Danchin, Auteur ; Jesus M. Aviles, AuteurCovariation between melanin-based colorations and other phenotypic attributes has been rarely measured simultaneously in males and females. Such covariations and mechanisms mediating them have crucial importance determining the signalling functi[...]
Article
Jesus M. Aviles, Auteur ; Juan M. Sanchez, Auteur ; Francisco J. Medina, AuteurThe responses of wintering cranes from southwestern Spain (Serena region) to potential predators were studied. Three different behavior patterns were observed when the predators appeared: flight, forming of dense groups on the ground as well as [...]
Article
Jesus M. Aviles, Auteur ; Emilio Costillo, AuteurThe selection of breeding habitats by Rollers (Coracias garrulus) is analysed in the southwestern Iberian Peninsula. Rollers selected positively areas where two years set-aside occurs ("posios") with holm-oak trees, though this substrate was sca[...]
Article
Elena Macías-Sanchez, Auteur ; Juan G. Martinez, Auteur ; Jesus M. Aviles, Auteur ; Manuel Soler, AuteurThe appearance of plumage in brood parasites represents an evolutionary conflict between sexual selection that favours colourful plumages, and parasite-host coevolution that favours crypsis. In this study we quantified the degree of sexual dimor[...]
Article
Juan Rodriguez, Auteur ; Jesus M. Aviles, Auteur ; Deseada Parejo, AuteurThe installation of nestboxes is a widely used conservation measure for enhancing habitat suitability for cavity-nesting birds wherever natural holes are scarce. However, nestboxes may attract birds to unsuitable breeding places or induce a non-[...]
Article
Deseada Parejo, Auteur ; Nadia Silva, Auteur ; Jesus M. Aviles, AuteurThe immune system has a crucial importance determining animal health and survival. Its maintenance and activation are costly and usually trade with other physiologically costly functions. In birds, number and size of siblings in a nest are likel[...]
