The genus Ilia Leach, 1817 consist of two species, Ilia nucleus and I. spinosa Miers 1881. In European continental waters the genus is represented solely by I. nucleus, a common species distributed from the Mediterranean to the Cape Verde Islands. However, during a biodiversity monitoring project carried out in the Gulf of Cádiz in 2013, an unusual specimen of Ilia was collected. The sample was i…

Giant kelp (Macrocystis pyrifera) is a vital primary producer in marine ecosystems due to its high net primary production (NPP) and carbon sequestration potential. This study investigated the NPP and carbon dynamics of farmed giant kelp at a farm site in Shearwater Bay, Lüderitz, Namibia, from May 2023 to April 2024. The study assessed giant kelp biomass, canopy area, seawater temperature, nitrat…

Raphidiopsis raciborskii is a filamentous bloom-forming cyanobacterium, considered as a cosmopolitan species. Some strains of R. raciborskii are capable of producing toxins, e.g. cylindrospermopsin (CYN) that greatly threatens human health. One of the most studied cyanotoxins is CYN, and is receiving increasing scientific attention due to its global distribution, bioaccumulation, and multiorgan t…

Nudibranchs and Sacoglossa are a group of marine mollusks that have been the subject of extensive research in many regions. While the Iberian Peninsula has a rich history of nudibranch studies, the Valencian Community remains relatively unexplored. This study aims to address this knowledge gap by providing the first comprehensive faunal catalogue of sacoglossa and nudibranchs in this region, cont…
