Early-life environmental conditions influence parasitism at adulthood and life-history of a cuckoo host

Jesús Miguel Avilés
Environmental conditions experienced by individuals early in life can extend into adult phenotypes with potential fitness consequences. Early life environmental effects can be relevant for hosts because bad early life conditions may impair host cognition increasing the risk of future parasitism or lowering parasite recognition. Here we provide a first test of this possibility by using data from a 16-year study of individually marked female magpie Pica pica hosts for which we know natal and...

Phenotypic and Genetic data for \"Evolution of fruit and seed traits during almond naturalization\"

Rafael Rubio De Casas, Andres Barea Marquez, Francisco Ocaña-Calahorro, Rodrigo Balaguer-Romano, José María Gómez, Eugene W. Schupp, Raquel Sanchez-Perez, Jesus Guillamon & Joanna Zhang
1- Cultivated plant species often naturalize and enter wild communities in a process known as feralization. To successfully feralize, crops must overcome ecological barriers and may undergo selection on certain traits, diverging phenotypically and genetically from their crop ancestors. In spite of the agronomic and ecological relevance of crop feralization, the eco-evolutionary dynamics driving it remain understudied. 2- In this paper, we evaluated phenotypic and genotypic differentiation in fruit and seed traits during the naturalization...

Agricultural intensification erodes taxonomic and functional diversity in Mediterranean olive groves by filtering out rare species

Rubén Tarifa, Carlos Martínez-Núñez, Francisco Valera, Juan P. González-Varo, Teresa Salido & Pedro J. Rey
1. Agri-Environmental Schemes (AES) have been proposed to mitigate the impact of agriculture on both taxonomic and functional biodiversity. However, a better knowledge of the mechanisms involved in the loss of agrobiodiversity is needed to implement efficient AES. An unbalanced effort on research towards arable lands compared to permanent crops, and on fauna relative to plants, is patent, which limits the generalization of AES effectiveness. 2. We evaluated the effects of agricultural management and landscape...

Partitioning beta diversity to untangle mechanisms underlying the assembly of bird communities in Mediterranean olive groves

Vicente García-Navas, Carlos Martínez-Núñez, Rubén Tarifa, Antonio J. Manzaneda, Francisco Valera, Teresa Salido, Francisco M. Camacho & Pedro J. Rey
Aim: We investigated taxonomic and functional beta diversity of bird communities inhabiting Mediterranean olive groves subject to either intensive or extensive management of the ground cover and located in landscapes with different degrees of complexity. Location: Andalusia, southern Spain. Methods: We partitioned taxonomic and functional beta diversity into its two additive components, turnover and nestedness. We also explored the contributions of single sites to overall beta diversity (LCBD) and separated the effects of species replacement...

Moonlight influence on quality of nestlings of scops owls depends on paternal coloration

Jesús Avilés, Angel Cruz-Miralles & Deseada Parejo
The moon might favour the maintenance of colour polymorphism via disruptive selection if the different colour variants performed differently in terms of prey capture under different moonlight levels. Moonlight, however, may affect prey capture as a by side effect of its influence on prey behaviours. Here we combine data of parental provisioning and owlets' quality with one ex-situ study of grasshoppers' activity to test whether Eurasian scops owls (Otus scops) with different plumage colour and...
