Human pressures are leading to the replacement of macroalgal forests by alternative opportunistic species on shallow temperate reefs. Nonetheless, the ecological consequences of habitat reconfiguration for coastal biodiversity and ecosystem functioning remain poorly quantified. By means of a field study, we compared the metabolic functioning and biodiversity of macroalgal forests dominated by the fucoid Ericaria brachycarpa at...

New records of introduced species in the Mediterranean Sea (December 2025)

Studies of non-indigenous species (NIS) often tend to focus on medium and large-sized taxa with potential for remarkable ecological and/or economic impact, whereas the early detection of small invertebrates is often delayed due to taxonomic challenge, lack of consistent, standardised monitoring efforts and limited funding. This study represents the first records of the marine amphipod Laticorophium baconi (Shoemaker, 1934) in...

This paper is a collection of novel distributional records of 20 species belonging to 8 phyla (Chlorophyta, Rhodophyta, Cnidaria, Ctenophora, Annelida, Mollusca, Arthropoda and Chordata) from 11 Mediterranean countries, namely, Spain: an additional record of the Canary dentex Dentex canariensis is reported from Spain (Valencia), this is the northernmost record of this species in the Mediterranean; Algeria: the first documented...
