Invertebrate diversity associated with a shallow rhodolith bed in the Mediterranean Sea (Mar Piccolo of Taranto, south‐east Italy)

open access: yesAquatic Conservation: Marine and Freshwater Ecosystems, Volume 34, Issue 1, January 2024.
Abstract Rhodoliths, formed by free‐living coralline algae, are distributed worldwide, and the rhodolith beds (RBs) that they form are recognized as structurally complex habitats. In the Mediterranean, they are generally distributed in the mesophotic zone, at depths of 30–100 m; so far, only a few shallow RBs (<2 m) have been reported (e.g. Îles Kuriat,

Ocean deoxygenation caused non‐linear responses in the structure and functioning of benthic ecosystems

open access: yesGlobal Change Biology, Volume 30, Issue 1, January 2024.
Over the past decades, there has been a gradual decline in global ocean oxygen concentrations due to climate change (ocean warming) and human activities (eutrophication). How this long‐term deoxygenation affects the macrobenthic communities and sediment biogeochemistry remain elusive.
