A widespread picornavirus affects the hemocytes of the noble pen shell (Pinna nobilis), leading to its immunosuppression
(Frontiers, 2023-12-13)
Introduction: The widespread mass mortality of the noble pen shell (Pinna nobilis) has occurred in several Mediterranean countries in the past 7 years. Single-stranded RNA viruses affecting immune cells ...
Point pattern analysis as a tool for assessing disease spread and population features in remaining sanctuaries of the critically endangered bivalve Pinna nobilis
(Elsevier, 2022-06-15)
An emergent disease has relegated populations of the Mediterranean pen shell, Pinna nobilis L. critically endangered to sanctuaries featuring salinities outside the 36.5 to 39 range. Point pattern ...
Herbivore control in connected seascapes: habitat determines when population regulation occurs in the life history of a key herbivore
(Wiley, 2018-02-08)
Herbivore outbreaks often trigger catastrophic overgrazing events in marine macrophyte ecosystems. The sea urchin Paracentrotus lividus, the dominant herbivore of shallow Mediterranean seascapes, is ...
Vibrio mediterranei, a Potential Emerging Pathogen of Marine Fauna: Investigation of pathogenicity using a bacterial challenge in Pinna nobilis and development of a species‐specific PCR
(Wiley, 2020-06-27)
Aims
Extreme mortality events affecting Pinna nobilis, some associated to Vibrio mediterranei, have depleted many populations of this bivalve. The objective of this study was to demonstrate pathogenicity ...
Molecular identification, life cycle characterization, and hatchery seed production of dwarf oysters from the Ebro Delta (Spain)
(EDP Sciences, 2022-05-20)
Dwarf oysters in the Ebro Delta are only observed growing on local pen shells, Pinna nobilis L., currently under extinction risk. The species identification of these populations is uncertain, given ...
Trophic plasticity in the sea urchin Paracentrotus lividus, as a function of resource availability and habitat features
(Inter Research, 2020-03-05)
Factors controlling herbivory pressure are of central importance in shaping the seascape. In the Mediterranean, the sea urchin Paracentrotus lividus is considered as a keystone herbivore in seagrass ...
Pinna nobilis in suboptimal environments are more tolerant to disease but more vulnerable to severe weather phenomena
(Elsevier, 2020-11-30)
We examined a disease outbreak of the fan mussel, Pinna nobilis (L.), in the Alfacs Bay (South Ebro Delta, Spain) during a period of two years in three zones exposed to a summer salinity gradient resulting ...
Pristine vs. human-altered Ebro Delta habitats display contrasting resilience to RSLR
(Elsevier, 2018-11-23)
River deltas are ecologically and economically valuable coastal ecosystems but low elevations make them extremely sensitive to relative sea level rise (RSLR), i.e. the combined effects of sea level rise ...
Prism substructures in the shell of Pinna nobilis (Linnaeus, 1758), Mollusca – Evidence for a three-dimensional pulsed-growth model
(Elsevier, 2020-07-20)
In the shells of the Pelecypods belonging to the Pinnidae family, the calcareous prismatic units of the outer layer are long-standing references for biomineralization studies. To elucidate how the ...
Assessment of marine benthic diatom communities: insights from a combined morphological–metabarcoding approach in Mediterranean shallow coastal waters
(Elsevier, 2022-01-18)
We investigated the advantages and disadvantages of light microscope (LM)-based identifications and DNA metabarcoding, based on a 312-bp rbcL marker, for examining benthic diatom communities from ...
