Using Photographs in Fishers’ Ecological Knowledge Research: A Review and Field Study on Small‐Scale Fishers’ Knowledge of Coastal Habitats in the Central Mediterranean Sea

Aquaculture, Fish and Fisheries, Volume 6, Issue 4, August 2026.
ABSTRACT Fishers interact daily with coastal environments, which generate a deep understanding of habitat characteristics, species associations and ecological change. Fishers’ ecological knowledge (FEK) is therefore a critical source of insight for marine science, offering observations that uniquely complement scientific data and, when incorporated ...

Experimental evidence that intra-specific competition in seagrass meadows reduces reproductive potential in the sea urchin Paracentrotus lividus (Lamarck)

Scientia Marina, 2005
To better understand the biological controls that regulate sea urchin dynamics, we studied the effects of potential inter- and intra-specific competition for food on several biological variables of the main sea urchin in the Mediterranean (Paracentrotus ...

Use of Invasive Rugulopteryx okamurae Beach Wrack as Habitat and Food by Talitrus saltator

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 8, August 2026.
ABSTRACT The introduction of non‐native algae into coastal waters has increased worldwide, causing a range of ecological and socio‐economic impacts. However, when stranded on beaches as wrack, these invasive algae can provide refuge and food for supralittoral organisms, potentially benefiting local fauna communities and beach functioning. In this study,

Reconsidering the role of introduced species in the climate‐affected and highly invaded eastern Mediterranean

Conservation Biology, Volume 40, Issue 4, August 2026.
Abstract Bioinvasions are considered mostly as a biodiversity and conservation hazard, but in specific situations, introduced species can bring ecological or socioeconomic benefits. We assessed the social–ecological role of marine introduced species in the eastern Mediterranean Sea—a global hotspot of bioinvasions and extirpations—and their potential ...

Monitoring the Colonisation Dynamics of Rugulopteryx okamurae on Algal Communities in the Northwestern Mediterranean Sea

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 7, July 2026.
ABSTRACT Biological invasions are a major driver of biodiversity loss, causing profound and often irreversible ecological changes. Among these invaders, the brown alga Rugulopteryx okamurae provides a striking example. Since its arrival in 2016 in Calanques National Park (Marseille, southern France), it has drastically transformed underwater landscapes

Benthic megafauna and the functioning of macroalgal forests and urchin barrens

Oikos, Volume 2026, Issue 7, July 2026.
Two temperate rocky reef food‐web models, representing the trophic diversity of the Mediterranean rocky reef communities, were built for the two stable states: macroalgal forests and barren grounds, which are characterized by opposite amounts of erect macroalgal biomass.

Possible role of microtubules in vesicular transport of matrix protein during sea urchin larval biomineralization

Developmental Dynamics, Volume 255, Issue 6, Page 585-601, June 2026.
Abstract Background Biomineralization is a vital biological process through which organisms produce mineralized structures such as shells, skeletons, and teeth. Microtubules are essential for biomineralization in various eukaryotic species; however, their specific roles in this process remain unclear.

Sexual dimorphism in the sea urchin Paracentrotus lividus: morphological and biochemical analysis

, 2010
As most echinoderms, the sea urchin Paracentrotus lividus is a gonochoric species without an evident sexual dimorphism. This characteristic obviously represents a disadvantage in those experimental contexts, where could be helpful to distinguish the sex ...
