A pioneering longterm experiment on mesophotic macrofouling communities in the ...
Canning-Clode, João; Gizzi, Francesca; Braga-Henriques, Andreia; Ramalhosa, Patrício; Abreu, Pedro; Álvarez, Soledad; Biscoito, ManuelThe mesophotic zone represents one of our planet's largest and least explored biomes. An increasing number of studies evidence the importance of macrofouling species in marine ecosystems, but information on these communities and the factors influencing their structures at mesophotic depths remain poor. This lack of understanding limits our ability to predict anthropogenic impacts or conduct restoration operatio...
Exploring foraging preference of local fish species towards non-indigenous foul...
Chebaane, Sahar; Pais, Miguel Pessanha; Engelen, Aschwin; Ramalhosa, Patrício; Silva, Rodrigo; Gizzi, Francesca; Canning-Clode, JoãoNon-indigenous species (NIS) spread from marinas to natural environments is influenced by niche availability, habitat suitability, and local biotic resistance. This study explores the effect of indigenous fish feeding behaviour on NIS proliferation using fouling communities, pre-grown on settlement plates, as two distinct, representative models: one from NIS-rich marinas and the other from areas outside marinas...
Citizen science and expert judgement: A cost-efficient combination to monitor a...
Parretti, Paola; Monteiro, João Gama; Gizzi, Francesca; Martinez-Escauriaza, Roi; Alves, Filipe; Chebaane, Sahar; Almeida, Silvia; Pais, Miguel PessanhaMapping the distribution and evaluating the impacts of marine non-indigenous species (NIS) are two fundamental tasks for management purposes, yet they are often time consuming and expensive. This case study focuses on the NIS gilthead seabream Sparus aurata escaped from offshore farms in Madeira Island in order to test an innovative, cost-efficient combined approach to risk assessment and georeferenced dispersa...
First record of the marine snail Xenophora crispa (Gastropoda: Xenophoridae) fr...
N.B. Freitas, Magno; Ramalhosa, Patricio; Moreira, André; Canning-Clode, João; Gama Monteiro, JoãoThe marine snail Xenophora crispa (d' Orbigny, 1847) is recorded for the first time in Madeira Island (NE Atlantic). This species is currently distributed throughout the central and western Mediterranean, western Atlantic from France (Gulf of Biscay) to North Africa (up to Morocco) including the Archipelagos of the Azores, Canary Islands, and now Madeira. Taxonomic features and similarities between Xenophora cr...
Diversity and patterns of marine non-native species in the archipelagos of Maca...
Castro, Nuno; Carlton, James T.; Costa, Ana C.; Marques, Carolina S.; Hewitt, Chad L.; Cacabelos, Eva; Lopes, Evandro; Gizzi, FrancescaAims The present study is the first attempt to grasp the scale and richness of marine biological invasions in Macaronesia. We pioneered a comprehensive non-native species (NNS), inventory in the region to determine their diversity patterns and native distribution origins. NNS were defined here as the result of both introductions and range expansions. We also used statistical modelling to examine relationships a...
Seasonal variation in microplastics and zooplankton abundances and characterist...
Sambolino, Annalisa; Herrera, Inma; Álvarez, Soledad; Rosa, Alexandra; Alves, Filipe; Canning-Clode, João; Cordeiro, Nereida; Dinis, AnaThe ingestion of microplastics (MPs - plastic particles <5 mm) by planktivorous organisms represents a signif icant threat to marine food webs. To investigate how seasonality might affect plastic intake in oceanic islands' ecosystems, relative abundances and composition of MPs and mesozooplankton samples collected off Madeira Island (NE Atlantic) between February 2019 and January 2020 were analysed. MPs were fo...
Determination of phthalic acid esters and di(2-ethylhexyl) adipate in fish and ...
Sambolino, Annalisa; Ortega-Zamora, Cecilia; González-Sálamo, Javier; Dinis, Ana; Cordeiro, Nereida; Canning-Clode, João; Hernández-Borges, JavierIn the present study, the ammonium formate version of the QuEChERS method, considered highly advantageous in relation to instrument maintenance and other issues, was applied for the first time to extract a group of twelve phthalic acid esters (PAEs, i.e. dipropyl phthalate, DPP; diisobutyl phthalate, DIBP; dibutyl phthalate, DBP; diisopentyl phthalate, DIPP; di-n-pentyl phthalate, DNPP; dihexyl phthalate, DHP; ...

From plates to baits: using a remote video foraging system to study the impact ...
Chebaane, Sahar; Canning-Clode, João; Ramalhosa, Patrício; Belz, Janina; Castro, Nuno; Órfão, Inês; Sempere-Valverde, Juan; Engelen, AschwinMarinas are a gateway for the introduction and establishment of non-indigenous species (NIS). In these habitats, competition and predation are crucial determinants for NIS establishment and invasiveness. However, fish trophic preferences and biotic effects inside marinas are poorly known. This study proposes a novel method that combines the deployment of settlement plates to recruit different assemblages, follo...
The collapse of marine forests: drastic reduction in populations of the family ...
Bernal-Ibáñez, Alejandro; Gestoso, Ignacio; Wirtz, Peter; Kaufmann, Manfred; Serrão, Ester A.; Canning-Clode, João; Cacabelos, EvaSpecies of the genera Cystoseira, Ericaria, Gongolaria, and Sargassum (family Sargassaceae) are key components of the Mediterranean-Atlantic marine forests, essential for biodiversity and ecosystem functioning. Populations of these foundational species are particularly vulnerable to anthropogenic impacts, likely to be intensified under future scenarios of climate change. The decline and even disappearance of th...
