Miguel Ferrer, Alberto Gonzalez, Maria De Diego, Gema Pinero

Abstract — An efficient version of the affine projection (AP) algorithm, which is called FXAP-AC throughout the paper, is presented. This algorithm uses the filtered-x structure instead of the...

Accuracy of lightweight satellite telemetry: a case study in the Iberian Peninsula (2007)

Soutullo Bugallo, Álvaro Alberto, Cadahía Lorenzo, Luis, Urios Moliner, Vicente, Ferrer, Miguel, Negro, Juan José

Here we provide the first assessment of the accuracy of lightweight satellite transmitters (80 g) under actual operating conditions and the performance of the Argos system in southern Europe. To...

How far away in an hour? Daily movements of juvenile golden eagles (Aquila chrysaetos) tracked with satellite telemetry (2006)

Soutullo Bugallo, Álvaro Alberto, Urios Moliner, Vicente, Ferrer, Miguel

We tracked the daily movements of three juvenile golden eagles (Aquila chrysaetos) using satellite telemetry. Straight distances covered in an hour and throughout a day were calculated. Daily...

Biases in population diet studies due to sampling in heterogeneous environments: a case study with the Eagle Owl (2005)

Vincenzo Penteriani, Fabrizio Sergio, Max Gallardo, Miguel Ferrer

Many studies have reported variation in bird diet composition related to spatial variation in habitat quality and landscape heterogeneity. Most diet analyses involve collection of food items at a...

Post-fledging behaviour in Golden Eagles Aquila chrysaetos: onset of juvenile dispersal and progressive distancing from the nest (2005)

Soutullo Bugallo, Álvaro Alberto, Urios Moliner, Vicente, Ferrer, Miguel, García Peñarrubia, Santiago

Thirteen juvenile Golden Eagles Aquila chrysaetos were tracked during their first year of life using satellite telemetry. Distances to the nest attained during that period and the age at the onset of...

Dispersal of Golden Eagles Aquila chrysaetos during their first year of life (2004)

Soutullo Bugallo, Álvaro Alberto, Urios Moliner, Vicente, Ferrer, Miguel, García Peñarrubia, Santiago

Capsule: The area explored increased throughout the year and tended to be much larger for females than males. Aims: To explore how the process of juvenile dispersal unfolds spatially and temporally,...

Environmental stochasticity in dispersal areas can explain the ‘mysterious’ disappearance of breeding populations

Penteriani, Vincenzo, Otalora, Fermín, Sergio, Fabrizio, Ferrer, Miguel

We present the results of an individual-based simulation model, showing that increasing the mortality of non-breeding dispersers within settlement areas can lead to the extinction of species and...
