A Baseline for the Conservation of the Native and Protected Centrostephanus longispinus (Philippi, 1845) and the Management of the Invasive Diadema setosum (Leske, 1778) (Echinoidea: Diadematidae) in the Mediterranean Sea

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 35, Issue 5, Page 1-12, May 2025.
ABSTRACT Centrostephanus longispinus (Echinodermata: Echinoidea) is an endemic and protected sea urchin species of the Mediterranean Sea. Another long‐spined sea urchin, Diadema setosum from the Red Sea, entered the Mediterranean Sea in 2006 and rapidly spread throughout the eastern basin. As a keystone competitive grazer, D.

Searchin' for Urchins: Utilising Museum Collections and Citizen Science to Assess Species on the Move in the Genus Tripneustes

Journal of Biogeography, Volume 52, Issue 5, May 2025.
ABSTRACT Aim With the global redistribution of species due to warming, accurately quantifying species distributions is critical to understanding patterns in biodiversity and range shift trajectories. The genus Tripneustes comprises globally important sea urchin taxa that graze seagrass and macroalgae and have the potential to transform ecosystems.

Geochemical signatures and nanomechanical properties of echinoid tests from nearshore habitats of Florida: environmental and physiological controls on echinoid biomineralization [PDF]

PeerJ
The mechanisms that regulate minor and trace element biomineralization in the echinoid skeleton can be primarily controlled biologically (i.e., by the organism and its vital effects) or by extrinsic environmental factors.
