Effects of sediment sulfides on seagrass Posidonia oceanica meristematic activity
Seagrass meadows rank amongst the most productive ecosystems on Earth, growing along tropical and temperate coasts, where they have important structural and biogeochemical functions (Hemminga & Duarte 2000). Seagrasses are clonal plants, which expand into new areas vegetatively by adding modules produced by the meristems located at the rhizome apices, rendering seagrass demographics and product...
متن کاملEffects of Posidonia Oceanica Beach-Cast on Germination, Growth and Nutrient Uptake of Coastal Dune Plants
Seagrass meadows play an important role in marine ecosystems. A part of seagrass production is also exported to adjacent coastal terrestrial systems, possibly influencing their functioning. In this work we experimentally analyzed the effect of Posidonia oceanica beach-cast on plant germination, growth, and nutrient uptake of two plant species (Cakile maritima and Elymus farctus) that grow on up...
متن کاملResponse of Posidonia oceanica seagrass and its epibiont communities to ocean acidification
The unprecedented rate of CO2 increase in our atmosphere and subsequent ocean acidification (OA) threatens coastal ecosystems. To forecast the functioning of coastal seagrass ecosystems in acidified oceans, more knowledge on the long-term adaptive capacities of seagrass species and their epibionts is needed. Therefore we studied morphological characteristics of Posidonia oceanica and the struct...
متن کاملAcclimation to different depths by the marine angiosperm Posidonia oceanica: transcriptomic and proteomic profiles
For seagrasses, seasonal and daily variations in light and temperature represent the mains factors driving their distribution along the bathymetric cline. Changes in these environmental factors, due to climatic and anthropogenic effects, can compromise their survival. In a framework of conservation and restoration, it becomes crucial to improve our knowledge about the physiological plasticity o...
متن کاملHPLC Determination of Chicoric Acid in Leaves of Posidonia oceanica
In this study, Posidonia oceanica (L.) Delile (Posidoniaceae), which is a widely distributed phanerogam in Aegean and Mediterranean coasts, was investigated for the phenolic compounds that have the potential to be used in pharmaceutical sciences. The leaves, separated as young and mature leaves, were extracted and analyzed by high-performance liquid chromotagraphy (HPLC). The younger leaves wer...
