    The process of agricultural abandonment has been taking place for the last decades all around Europe. This process has special effect on mountain livestock farming, as it is the case of that of Catalan Pyrenees, which is characterised by an extensive management of the herd between the alpine grasslands in summer and the hay meadow of the lower valleys in winter. The process of agricultural abandonment, apart from the obvious closing down of the exploitations, also implies a gradual decrease of the management intensity of the farming exploitation.

    Changes of vegetal cover in the Aragonese western Pyrenees are shown throughout the last 50 years. The evolution is characterized by a generalised revegetation process with an advance of shrubs and forests. The medium and low slopes show the most intense revegetation as a consequence of the agricultural abandonment and the decrease of the livestock pressure. Nevertheless, few vegetation changes are recorded in cultivated lands and the pastures located above timberline.

La actual demanda de servicios recreativos en el bosque genera una intensificación de estos riesgos, lo que precisa de una adecuada respuesta por todos los agentes implicados en la gestión.

    The Celta pig breed was the most important in Galicia (northwest of Spain) until beginning of the 20th century, suffering from this moment a continuous decrease caused by the introduction of improved breeds and their crosses. For this study 19 Celta pig breed from Santiaguesa genotype and 15 from Carballina genotype were used. Animals were weighted once at month during 12 months. To Santiaguesa genotype not significant differences (P>0.05) were observed until 198 days but it has been detected significant differences (P0.05) in any growth curve between gender.
