Satellite Tracking and Photographic-Identification as Connectivity-Based Tools ...
Weyn, Mieke; Marrero-Pérez, Jacobo; Sánchez Mora, Anna; Pimentel González, Atenary; Ferreira, Rita; Sambolino, Annalisa; Dinis, AnaIdentifying biogeographical patterns and important biological (blue) corridors can greatly contribute to conservation planning. Yet, this is particularly challenging when addressing pelagic species. In this study, satellite telemetry and photographic-identification data of short-finned pilot whales (Globicephala macrorhynchus) were used to identify preferred areas and pathways in the Macaronesia biogeographical...
Phthalates as plastic tracers in a pelagic food web from an open oceanic enviro...
Sambolino, AnnalisaA investigação científica nas ciências ambientais e biológicas preocupa-se cada vez mais dos efeitos adversos das atividades humanas. A poluição por plásticos tem recebido atenção global devido ao seu evidente impacto ambiental, especialmente nos ecossistemas marinhos. Os microplásticos (MPs), definidos como partículas de plástico com menos de 5 mm, são de particular preocupação devido à sua persistência e capa...
Optimization and validation of a micro–QuEChERS method for phthalates detection...
Sambolino, Annalisa; Rodriguez, Marta; De la Fuente, Jesus; Arbelo, Manuel; Fernández, Antonio; Kaufmann, Manfred; Cordeiro, Nereida; Dinis, AnaIn this study, an innovative method was developed to detect and quantify phthalates in fresh cetacean blubber. An adaptation of the ammonium formate QuEChERS method was used and adapted as a micro-extraction for small quantities of samples. Significantly, this technique utilized minimal quantities of reagents and salts, with the additional implementation of rigorous Quality Assurance/Quality Control protocols t...
Microplastic ingestion and plastic additive detection in pelagic squid and fish...
Sambolino, Annalisa; Iniguez, Eva; Herrera, Inma; Kaufmann, Manfred; Dinis, Ana; Cordeiro, Nereida; Sambolino, Annalisa; Iñiguez Santamaría, EvaThe ubiquitous presence of microplastics (MPs) in the ocean represents a potential threat to marine organisms, with poorly understood long-term adverse effects, including exposure to plastic additives. The present study investigated the ingestion of MPs in two epipelagic fish species (Trachurus picturatus and Scomber colias) and three pelagic squid spe cies (Loligo vulgaris, Ommastrephes caroli and Sthenoteuthi...
Behavioural Ecology Traits of Elusive Deep-Diver Whales Unravel a Complex Socia...
Badenas, Anja; Dinis, Ana; Ferreira, Rita; Sambolino, Annalisa; Hamard, Eliette; Berninsone, Leonardo G.; Fernandez, Marc; Alves, Filipe M. A.Knowledge of the role of individual associations has provided an insightful understanding of the structures of animal societies, especially in highly social mammals such as primates. Yet, this is unbalanced towards marine mammals, particularly to beaked whales, due to their elusive nature. In addition, information on the fundamental drivers of the social structure of these deep-diving animals is still scarce. H...
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; ...
Large-scale movements of common bottlenose dolphins in the Atlantic : dolphins ...
Dinis, Ana; Molina, Carlota; Tobeña, Marta; Sambolino, Annalisa; Hartman, Karin L.; Fernandez, Marc; Magalhães, Sara; Santos, Rui Peres dosWide-ranging connectivity patterns of common bottlenose dolphins (Tursiops truncatus) are generally poorly known worldwide and more so within the oceanic archipelagos of Macaronesia in the North East (NE) Atlantic. This study aimed to identify long-range movements between the archipelagos of Macaronesia that lie between 500 and 1,500 km apart, and between Madeira archipelago and the Portuguese continental shelf...
