Response of the non-indigenous Caulerpa racemosa ̊ (Forsskal) J. Agardh to the native seagrass Posidonia oceanica (L.) Delile: effect of density of shoots and orientation of edges of meadows
Caulerpa racemosa is a tropical green alga introduced into the Mediterranean as an immigrant from the Red Sea which has successfully fast-spread in the south-eastern and in the north-western part of the basin. C. racemosa occurs mostly in shallow but also in deep subtidal habitats colonising hard and soft substrata where turfs, erect algae and even seagrasses are present with the potential to p...
متن کاملDepth-specific fluctuations of gene expression and protein abundance modulate the photophysiology in the seagrass Posidonia oceanica
Here we present the results of a multiple organizational level analysis conceived to identify acclimative/adaptive strategies exhibited by the seagrass Posidonia oceanica to the daily fluctuations in the light environment, at contrasting depths. We assessed changes in photophysiological parameters, leaf respiration, pigments, and protein and mRNA expression levels. The results show that the die...
متن کاملExperimental evidence of chemical deterrence against multiple herbivores in the seagrass Posidonia oceanica
There is increasing evidence of the importance of herbivory in seagrass communities, but the factors that regulate seagrass–herbivore interactions remain largely unknown. Many terrestrial plants and marine algae chemically deter herbivores using secondary metabolites, yet their incidence and role on seagrasses have received little attention. Posidonia oceanica, the dominant seagrass in the Medi...
متن کاملBenthic inputs as predictors of seagrass (Posidonia oceanica) fish farm-induced decline
3 Fish farms represent a growing source of disturbance to shallow benthic ecosystems like 4 seagrass meadows. Despite some existing insights on the mechanisms underlying decline, efficient tools 5 to quantitatively predict the response of benthic communities to fish farm effluents have not yet been 6 developed. We explored relationships of fish farm organic and nutrient input rates to the sedim...
متن کاملTissue-specific transcriptomic profiling provides new insights into the reproductive ecology and biology of the iconic seagrass species Posidonia oceanica.
Seagrasses form extensive meadows in shallow coastal waters and are among the world's most productive ecosystems. Seagrasses can produce both clonally and sexually, and flowering has long been considered infrequent, but important for maintaining genetically diverse stands. Here we investigate the molecular mechanisms involved in flowering of the seagrass Posidonia oceanica, an iconic species en...
