Marine protected areas' positive effect on fish biomass persists across the steep climatic gradient of the Mediterranean Sea

open access: yesJournal of Applied Ecology, Volume 60, Issue 4, Page 638-649, April 2023., 2023
Our results suggest that sustained warming will likely reduce fish biomass in the Mediterranean Sea and shift community structure, requiring more conservative targets for fishery regulations. At the same time, protection from fishing will remain an important management tool even with future high‐water temperatures, and MPAs are expected to continue to ...

Blinded by the bright: How species‐poor habitats contribute to regional biodiversity across a tropical seascape

open access: yesDiversity and Distributions, Volume 28, Issue 11, Page 2272-2285, November 2022., 2022
Abstract Aim Conservation efforts have traditionally addressed the threat of biodiversity loss by prioritizing regions and habitats with high endemic species richness. However, species‐poor habitats often harbour distinct, valuable and/or functionally unique species that contribute to regional diversity.

Atherinidae

open access: yes, 2008
Atherinidae Atherina boyeri Risso, 1810 —Big-scale sand smelt The species is easily confused with A. presbyter. The sample ZMH 13570 (4 specimens, Funchal, Madeira, d'Abreu Nunes, 4 June 1930), originally identified as A. boyeri, was re-identified by us as A. presbyter. The presence of A. boyeri at Madeira appears very doubtful.
