dc.description.abstractEl éxodo rural y la desaparición del manejo tradicional agrícola durante el siglo pasado tuvo consecuencias en el medio rural, como la pérdida de biodiversidad en un gran número de grupos de plantas y animales. Los lameiros, pastizales semi-naturales que acumulan una gran cantidad de agua, actuando como corredores ecológicos y refugio para determinadas especies, se han visto fuertemente influidos por esa regresión. El presente trabajo pretende determinar si el abandono de las prácticas tradicionales está teniendo un efecto sobre las comunidades de saltamontes (Orthoptera) que habitan estos lameiros. Fueron capturados, en lameiros con diferente tipo de gestión, un total de 164 adultos pertenecientes a 19 especies, entre ellas varios endemismos ibéricos o iberobaleares. Nuestros resultados sugieren que el abandono de las prácticas está conduciendo a un cambio progresivo de las comunidades de ortópteros, con la desaparición de las especies más dependientes de los manejos practicados durante décadas, siendo estas especies sustituidas por otras mas eurioicas, lo que implicaría una disminución de la diversidad gamma a nivel paisajístico.pt_PT
dc.description.abstractThe rural exodus and the disappearance of traditional agricultural practices during the past century has had serious consequences for the rural space, like the loss of biodiversity in a large number of plants and animals. The lameiros, seminatural pastures which hold big quantities of water and act as habitat corridors and refuge for various species, have been deeply influenced by that regression. The present work aims to determine if the loss of traditional practices is having an effect on the grasshopper and bush cricket communities (Orthoptera) of the lameiros. We collected, at lameiros with different kinds of management, 164 adults belonging to 19 species, amongst them several Iberian and Iberian-Balearic endemics. Our results suggest that the loss of traditional agricultural practices in these pastures in north-eastern Portugal is progressively altering the orthopteran communities, with the disappearance of those species most heavily dependent on traditional uses and their replacement by more generalistic species, which would involve a decrease in gamma diversity at the landscape level.pt_PT
