Assessing naturalness of coastal dune ecosystems through community (citizen) science: A protocol for Mediterranean beaches

Ecological Solutions and Evidence, Volume 7, Issue 3, July–September 2026.
A standardized citizen science protocol enabled trained secondary school students to collect reliable data on beach and coastal dune naturalness across Italy. The method provides a scalable and cost‐effective tool to support ecological assessment, identify vulnerable sites and inform coastal conservation and management.

Decapod Crustacea of the Central Paratethyan Ottnangian Stage (middle Burdigalian): implications for systematics and biogeography

Geologica Carpathica, 2015
Decapod crustaceans from the Ottnangian (middle Burdigalian, Lower Miocene) of the Western and Central Paratethys remain poorly known. In this study, we review and re-describe mud shrimps (Jaxea kuemeli), ghost shrimps (Gourretia sp., Calliax michelottii)

Evidence of Cheliped Autotomy and Regeneration in the Lower Miocene Crab Achelous monspeliensis From Portugal

Ecology and Evolution, Volume 16, Issue 7, July 2026.
Crab autotomy with evidence of regeneration is described for the first time in the fossil record. Autotomy is a defensive behavior that affects more males than females of Achelous monspeliensis and may be related to mating season. ABSTRACT Autotomy—the voluntary shedding of a limb as a defensive response to predation, intraspecific aggression, or ...
