Datació de Posidonia oceanica mitjançant 210Pb

, 2021
La Posidonia oceanica és una fanerògama marina endèmica del Mediterrani. Es tracta d'una espècie molt important a les zones costeres, i en les últimes dècades la seva producció s'ha vist reduïda. En aquest estudi s'ha volgut demostrar la viabilitat d'utilitzar l'espècie Posidonia oceanica com a arxiu de contaminants al llarg del temps, alhora que s'han

Assessing the Contribution of Posidonia oceanica to Mediterranean Secondary Production Through Stable Isotope Analysis

Journal of Marine Science and Engineering
The role of seagrasses in providing a complex habitat for marine organisms is globally documented; however, few studies have investigated the trophic incorporation of endemic Mediterranean Posidonia oceanica into marine food webs. Meadows of P.

Structural determinants for red‐shifted absorption in higher‐plants Photosystem I

New Phytologist, Volume 248, Issue 5, Page 2331-2346, December 2025.
Summary Higher plants Photosystem I absorbs far‐red light, enriched under vegetation canopies, through long‐wavelength Chls to enhance photon capture. Far‐red absorption originates from Chl pairs within the Lhca3 and Lhca4 subunits of the LHCI antenna, known as the ‘red cluster’, including Chls a603 and a609.

Epiphytic hydroids on Posidonia oceanica seagrass meadows are winner organisms under future ocean acidification conditions: evidence from a CO2 vent system (Ischia Island, Italy)

The European Zoological Journal, 2021
Effects of ocean acidification (OA) on the plant phenology and colonization/settlement pattern of the hydrozoan epibiont community of the leaves of the seagrass Posidonia oceanica have been studied at volcanic CO2 vents off Ischia (Italy).

Na+-dependent NO3- uptake in leaf cells of the seagrass Posidonia oceanica (L.) Delile [PDF]

, 2015
Posidonia oceanica (L.) Delile is an endemic Mediterranean seagrass of recognized ecological significance and, as other seagrasses, this species has secondarily adapted to live in the marine environment.

Grazing halos reveal differential ecosystem vulnerabilities in vegetated habitats

Ecology, Volume 106, Issue 11, November 2025.
Abstract The dynamic balance between primary production and herbivory is key to the resilience of plant‐dominated ecosystems across the world. However, many vegetated ecosystems are becoming increasingly susceptible to herbivore‐triggered collapses, as this balance is disrupted due to predator declines, increasing nutrients, and other interacting ...

Feeding preferences of amphipod crustaceans Ampithoe ramondi and Gammarella fucicola for Posidonia oceanica seeds and leaves

Scientia Marina, 2019
The functional importance of herbivory in seagrass beds is highly variable among systems. In Mediterranean seagrass meadows, macroherbivores, such as the fish Sarpa salpa and the sea urchin Paracentrotus lividus, have received most research attention, so

Not All Aliens Come to Harm (Maybe): Pinctada radiata (Leach, 1814) Population and Habitat From a Coastal Lagoon (Central Mediterranean Sea)

Marine Ecology, Volume 46, Issue 6, November/December 2025.
ABSTRACT Pinctada radiata, Leach, 1814, is considered the first Indo‐Pacific bivalve introduced in the Mediterranean Sea after the Suez Canal opening and it is now reckoned among the 100 most invasive species within the basin. It is important to assess and describe its established populations in Mediterranean coastal ecosystems to understand the ...
