the presentation was also on the work carried out in Gorham ’ s Cave and in Doñana which examined in detail how climate changed affected the Gibraltar area in the past . This impact was seen dramatically in the form of massive land transformations associated with sea level change ; as Prof Finlayson explained , these changes were often erratic and abrupt , transforming the land in short periods .
Climate had its influence on vegetation and Prof Finlayson explained in detail our current knowledge of that vegetation based on pollen and charcoal studies in Gorham ’ s Cave and in Doñana . This information included the latest results which have been published in recent years . Despite the great transformations to the landscape in northern Europe during the glaciations , with much of the British Isles under ice , much of France covered by tundra , sea ice in the Bay of Biscay , and the polar front ( currently off Greenland ) reaching the latitude of Oporto , olives and other warm-loving Mediterranean plants continued to grow in Gibraltar . These glacial refugial conditions for plants translated into pockets of survival for much of the European fauna , including birds but also people . Remarkably , the re-colonisation of Europe after the glaciations was undertaken by pioneer populations from these climatic refugia . Professor Finlayson concluded with an analysis of the survival of Palaearctic-African migratory birds in these locations , the only ones in Europe , based on the bones of these species retrieved from Gorham ’ s Cave .”

El cambio climático tal y como afectó a Gibraltar en el pasado y su impacto en las poblaciones de aves .
La profesora Geraldine Finlayson , del Museo Nacional de Gibraltar , impartió recientemente un seminario web sobre el tema « Las condiciones del Pleistoceno y Holoceno para los migrantes transaharianos en el extremo norte del desierto del Sáhara », organizado por el prestigioso Instituto Ornitológico Suizo . En un comunicado de prensa se explica que « el seminario web se impartió a una audiencia internacional de científicos el viernes 14 de abril y fue recibido con gran interés .
