- W66146205 abstract "espanolEn un programa de investigacion sobre cabos y pequenas islas, nuestra atencion se ha centrado en la Isla de Molara, situada en la Cerdena norte oriental, de substrato siliceo, con una superficie de 3,498 km2 y una extension de la costa de 10 km. La flora de la isla ha sido estudiada por varios botanicos que han identificado 402 entidades floristicas de las cuales 360 ya fueron determinadas por Picci. Los estudios actuales han permitido encontrar 384 especies englobadas en 83 familias y 252 generos. Comparando la flora actual con la de hace tres decadas, 86 taxones son nuevos para la isla, 285 han sido confirmados y 104 no se han observado. Las variaciones dependen de los diferentes usos del territorio en los ultimos 40 anos, durante los cuales ha des-aparecido la actividad agricola y se ha reducido al minimo la actividad ganadera. Por lo que se refiere a las modificaciones del paisaje vegetal, estas se hacen mas evidentes en las zonas antes cultivadas y explotadas por la ganaderia, donde son frecuentes plantulas y formas arbustivas de Olea europaea L. var. sylvestris Brot., Rhamnus alaternus L., Phillyrea angustifolia L. y numerosos arbustos que indican como la fitocenosis esta dando lugar a formaciones mas evolucionadas. EnglishIn the framework of a research program involving headlands and small islands, our attention was drawn to the island of Molara, situated in north eastern Sardinia. It is a granite outcrop, covering 3,498 km2 and with a coastline extension of some 10 km. Its flora has been the subject of study by various botanists who overall listed a floristic contingent of 402 taxa, 360 of which were identified by Picci. Our studies have recorded 384 taxa belonging to 83 families and 252 genera. Comparison of the present-day and previous data shows that 86 taxa are new, 285 are confirmed and 104 have not been rediscovered. The variations depends on the different uses to which the island has been put over the last 40 years, a period during which farming activity carne to a halt and stock rearing was reduced to a minimum. As regards modifications of the vegetation landscape, these are most evident in areas at one time cultivated or used for grazing, where we find numerous bushes and bush forms of Olea europaea L. var. sylvestris Brot., Rhamnus alaternus L., Phillyrea angustzfolia L., indicating that phytocoenoses are developing in the direction of more evolved formations." @default.
