[EN] In the Gulf of Lion Campaign 109 bluefin were tagged with conventional tags measuring between 74 cm and 108 cm fork length (LH). Five of these specimens had an electronic mark mini-patt placed on them. The campaign ...

[ES] Cada vez más, la escalada es practicada por un número mayor de personas. Las molestias ocasionadas por los seres humanos al ecosistema, donde conviven diferentes especies de aves, pueden afectar a la biología reproductora ...

In some animal populations, immigrants have lower survival than philopatric individuals. Costs of dispersal or low phenotypic quality of dispersers may explain the pattern. However, apparent adult survival estimates, which ...

[EN] Differential traits (e.g., feeding at different heights in trees) have evolved to allow the coexistence of putative competitors; such traits have been well studied in small passerines (e.g., Paridae), mainly during ...

[EN] The integration and synthesis of the data in different areas of science is drastically slowed and hindered by a lack of standards and networking programmes. Long-term studies of individually marked animals are not an ...

Capsule: We found high diet overlap and different uses of space and time between Moustached Warblers Acrocephalus melanopogon and Reed Warblers Acrocephalus scirpaceus breeding in sympatry at a marshland in Spain. Aims: ...

Después de llevar a cabo muestreos diurnos por distancias en la Reserva Valenciana de Caza de la Muela de Cortes (R.V.C.M.C.) dirigidos a las poblaciones de especies de caza mayor, principalmente muflón y cabra montés, ...

Wetlands are naturally patchy habitats, but patchiness has been accentuated by the extensive wetlands loss due to human activities. In such a fragmented habitat, dispersal ability is especially important to maintain gene ...

In the Iberian Peninsula, populations of two subspecies of the Reed Bunting Emberiza schoeniclus have become increasingly fragmented during the last decades when suitable habitats have been lost and/or the populations have ...
