摘要: Abstract This study examines the effects of altitudinal, temperature and aspect gradients on vascular plant species richness mountain tops in Sierra Nevada (Spain) at different spatial scales (1 m2 quadrats, plot clusters 4 m2, upper summit area down to 5-m contour line, entire 10-m line). The methodology follows Global Observation Research Initiative Alpine Environments (GLORIA) programme. Floristic soil data eight summits sites two neighbouring regions high part (from 2668 m 3327 m a.s.l.) were used this study. In total, 102 taxa recorded (84 genera; 29 families). decreased, whereas proportion endemic increased with elevation. There significant linear relationships between altitude average each scale. However, there was no relationship variables. Facing continued clim...
