dc.description.abstractClonal plants can reproduce sexually and clonally, expressing different proportions of these different life histories in distinctive environments. In seagrass meadows, light attenuation hinders marine plant colonization in deeper areas of its vertical distribution. Therefore it is expected that the fluorescence maximum quantum yield of seedlings will be higher at deep limits of the meadow relative to shallower depths. We hypothesized that seagrass seedlings experience higher mortality in deeper areas of the meadows than at shallower levels. Our objective was to test survival of seagrass seedlings along a depth gradient in meadows of Cymodocea nodosa in the Canary Islands. Seedlings germinated in laboratory conditions, were transplanted to a natural meadow at three water depths: shallow (5 m), medium (8 m) and deep (12 m). Transplanted seedlings were monitored by measuring maximum quantum yield, leaf length, number of leaves per shoot and survival. Our data suggest that light does not hinder survival of seedlings along the depth gradient of the meadow. Before establishing clonal growth, seedlings in deeper areas had higher survival rates than those in shallow areas. Even though seeds are present at shallow depths and sexual allocation is high, sexual contribution can be lower than expected due to seedling loss.
