Abstract Aims The present study is the first attempt to grasp scale and richness of marine biological invasions in Macaronesia. We pioneered a comprehensive non‐native species (NNS), inventory region determine their diversity patterns native distribution origins. NNS were defined here as result both introductions range expansions. also used statistical modelling examine relationships among richness, anthropogenic activities, demographic geographical variables across Location Methods A...

Quaternary climatic fluctuations had major impacts on species’ distributions over the last 2.5 Myr. Expansions and contractions of polar ice caps throughout glacial cycles strongly affected terrestrial fauna flora whereas eustatic sea level variations consequences rocky-shore communities. The effect these episodes marine organisms inhabiting oceanic islands is still poorly understood. We analysed genetic structure mussel Brachidontes puniceus from Cape Verde Islands using mitochondrial...
The introduction of non-indigenous species (NIS) induces severe impacts on marine biodiversity and ecosystems. Macaronesia is an ecologically relevant region where several NIS were detected recently. For the first time, a standard experimental approach was designed to examine biofouling assemblages investigate across region. In this context, sessile examined in four recreational marinas all Macaronesian archipelagos from 2018 2020: Azores, Madeira, Canary Islands, Cabo Verde. We hypothesised...
A new species of spoon-nose eel, Mystriophis caboverdensis sp. nov., is described from the Cabo Verde Archipelago based on a single adult specimen (723 mm TL). It co-occurs in tropical eastern Atlantic with two similar looking species, M. rostellatus (Richardson) and crosnieri Blache. The distinguished both congeners by its uniquely advanced position dorsal fin origin, inner outer maxillary teeth subequal size, shorter head predorsal length, fewer pectoral rays, more lateral-line pores,...
Oceanic archipelagos are the ideal setting for investigating processes that shape species assemblages. Focusing on keyhole limpets, genera Fissurella and Diodora from Cape Verde Islands, we used an integrative approach combining molecular phylogenetics with ocean transport simulations to infer distribution patterns analyse connectivity. Dispersal simulations, using pelagic larval duration currents as proxies, showed a reduced level of connectivity despite short distances between some...
DNA metabarcoding is widely used to characterize the diet of species, and it becomes very relevant for biodiversity conservation, allowing understanding trophic chains impact invasive species. The need cost-effective monitoring methods fostered advances in this technique. One question that arises which sample type provides a better representation.Therefore, with study, we intended evaluate if there were differences estimates according section gastrointestinal tract analysed section(s)...
The Azorean barnacle, Megabalanus azoricus (Pilsbry, 1916), is a Macaronesian endemic whose obscure taxonomy and the unknown relationships among forms inhabiting isolated Northern Atlantic oceanic islands investigated by means of molecular analysis herein. Mitochondrial data from 16S rRNA COX1 genes support its current species status, tropical ancestry, taxonomic homogeneity throughout distribution range. In contrast, at intraspecific level based on control region sequences, we detected an...
Tunas of the family Scombridae are paramount importance for fisheries and international seafood trade. In order to ensure a sustainable use these valuable resources, it is crucial that stock delineation management plans in accordance. Here, we examined population genetic structure two data-poor scombrid species wahoo (Acanthocybium solandri) bigeye tuna (Thunnus obesus), both growing significance fisheries. Our study employed whole-genome sequencing methods conduct most extensive genomic...
The spider crabs of the genus Pisa Leach, 1814 (Epialtidae: Pisinae) are reviewed in this study based on morphological and molecular data (16S COI genes). From these results, a new genus, Afropisa n. gen., is established for clade composed carinimana Miers, 1879, calva Forest Guinot, 1966 sanctaehelenae Chace, carapace morphology, rostrum, pterygostomian tubercles male gonopod 1. Additionally, Lissa chiragra (Fabricius, 1775) transferred to (adults larvae) evidence. Furthermore, status...
Agama agama is a successful invader that was recently introduced to Santo Antão Island of the Cape Verde archipelago. The species then noted be present also in São Vicente and Santiago Islands but geographic origin introductions remains undetermined. Given its wide range taxonomic identification problems, we compared new 16S RNA sequences with available order determine if some geographical structure allowed country provenance number introduction events on Islands. Some genetic diversity...
The genus Acanthonyx Latreille, 1828 (Majoidea, Epialtidae) contains 17 or 18 known species, depending on competing taxonomic views, that are widely distributed across the world. Morphologically, most species look superficially alike, and therefore, similar concepts have been described under different names. Consequently, there is today a considerable list of synonyms, which further complicates taxonomy . In this study, we conducted phylogeographical phylogenetic analysis populations in NE...
Abstract The snowflake coral Carijoa riisei is one of the most invasive and successfully adapting species in coastal marine environment. This can disperse through ballast waters or fouling on hull ships, which allows it to expand very quickly areas where not native. Recently C. was identified Porto Grande Bay São Vicente island Cabo Verde Islands. We analysed mitochondrial nuclear DNA sequences from specimens collected at this locality determine potential origin invasion. Lack genetic...

Abstract Tarentola gigas (Bocage, 1875) is the largest gecko living in Cabo Verde Archipelago. It subdivided into two subspecies, one confined to Branco Islet, brancoensis (Schleich, 1984), and another Raso 1875). These islets were classified as Integral Natural Reserves further studies on species are needed outline more assertive conservation measures. Thus, this study aims integrate for first time genetic, morphometric meristic data test if there significant differences between these...
The sea urchin Diadema africanum is a macro-herbivore found in the rocky reef systems of West African region and Macaronesian archipelagos. Over several decades, high densities this species have generated marine barrens certain areas at Canary Islands. In contrast, more recently, during last few years, has suffered mass mortality events that continue to present day. study, we used 9,109 Single Nucleotide Polymorphisms (SNPs) fragment mitochondrial gene evaluate species' population structure,...
The rough pen shell Pinna rudis Linnaeus, 1758 (family Pinnidae), a mollusc with an Atlantic–Mediterranean distribution, is able to live in coarse sandy substrates. Considering its structure and ecological characteristics, P. can enhance biodiversity by providing substrate for settlement on shell. For this reason, we compared the diversity of benthic taxa around shells species shells, at Matiota Beach, São Vicente Island, Cabo Verde. We sampled area 900 m2 recorded data situ estimate...
