Connectivity patterns and gene flow among Chelon ramada populations
Pereira, Esmeralda; Mateus, Catarina Sofia; Alves, Maria Judite; Almeida, Rita; Pereira, Joana; Quintella, Bernardo R.; Almeida, Pedro R.Catadromous species, such as the thinlip grey mullet Chelon ramada (Risso 1827), exhibit complex life history traits and migratory behaviours that have different repercussions at the population level and species genetic structure. To study the genetic variation and infer patterns of gene flow and population connectivity along species’ distribution across the Northeast Atlantic coast and the Mediterranean Sea, 4...
The decline of the ecosystem services generated by anadromous fish in the Iberi...
Almeida, Pedro R.; Mateus, Catarina Sofia; Alexandre, Carlos M.; Pedro, Sílvia; Boavida-Portugal, Joana; Belo, Ana Filipa; Pereira, EsmeraldaThis work aims to present an historical review of the ecosystem services provided by anadromous fish (i.e., species that migrate from the sea to the river to spawn) throughout Human time, as well as of the main related threats, focusing on the Iberian Peninsula region. Anadromous fish provide important provision, cultural, regulatory and supporting ecosystem services across their distribution range and have bee...

Cross-referencing unidentified fish sound data sets to unravel sound sources: a...
Vieira, Manuel; Ríos, Noelia; Muñoz-Duque, Sebastian; Pereira, Jodanne; Carriço, Rita; Fernandez, Marc; Monteiro, João G.; Pais, Miguel PessanhaThere is growing evidence that studying aquatic acoustic communities can provide ecologically relevant information. Understanding these communities may offer unique insights into species behaviour and ecology, while consolidating passive acoustic monitoring as a tool for mapping the presence of target species or estimating changes in aquatic biodiversity. Fish can be significant soundscape contributors, but mos...
Fully protected marine areas linked to reduced home ranges of fishes
Ohayon, Sarah; Abecasis, David; Almeida, Pedro R.; Alós, Josep; Aspillaga, Eneko; Belo, Ana Filipa; Costa, José Lino; Di Franco, AntonioHome range size is a fundamental trait that can affect the probability of fish being harvested and, at the same time, may be affected by fishing. The relationship between home range size and fishing will impact the effectiveness of fully protected areas (FPAs), as it will influence the number of fish moving into fished areas, affecting both spillover and edge effects. One hypothesis is that individuals within F...
Seascape genomics reveals limited dispersal and suggests spatially varying sele...
Baltazar-Soares, Miguel; Britton, Robert; Pinder, Adrian; Harrison, Andrew J; Nunn, Andrew; Quintella, Bernardo R.; Mateus, CatarinaSea lamprey Petromyzon marinus is an anadromous and semelparous fish without homing behaviors. Despite being a freshwater, free-living organism for a large part of their life cycle, its adulthood is spent as a parasite of marine vertebrates. In their native European range, while it is well-established that sea lampreys comprise a single nearly-panmictic population, few studies have further explored the evolutio...
Assessment of Fish Passage and Behaviour through a Tidal Weir Using an Underwat...
Oliveira, Roberto; Alexandre, Carlos; Quintella, Bernardo R.; Rato, Ana Sofia; Pedro, Sílvia; Almeida, Pedro R.The “Rio Novo do Principe” temporary tidal weir is built annually in the brackish section of the Vouga river to prevent saline intrusion during the low-flow summer period, thus securing freshwater abstraction for agricultural and industrial uses. Compatibilization between these objectives and successful fish migration, coupled with adequate biological monitoring of this infrastructure, is essential, since it is...
Migratory Patterns of Two Potamodromous Fish Species Assessed through Fish-Pass...
Rato, Ana Sofia; Alexandre, Carlos; Pedro, Sílvia; Mateus, Catarina; Pereira, Esmeralda; Belo, Ana Filipa; Quintella, Bernardo R.; Quadrado, Maria F.The Iberian barbel (Luciobarbus bocagei Steindachner, 1864) and the Iberian nase (Pseudochondrostoma polylepis Steindachner, 1864) are two potamodromous species that migrate upstream in freshwater environments to reproduce. Thus, river fragmentation is a major threat to these species, and fish passes are one of the most-used mitigation measures to restore the longitudinal connectivity of impounded rivers, enabl...
Meso- and Micro-Habitat Preferences of European River and Brook Lamprey in a Me...
Oliveira, Inês; Quintella, Bernardo R.; Mateus, Catarina S.; Alexandre, Carlos M.; Almeida, Pedro R.The European river (Lampetra fluviatilis Linnaeus, 1758) and brook (Lampetra planeri Bloch, 1784) lampreys are considered ‘paired species’, i.e., they are closely related and morphologically very similar but have distinct modes of adult life (anadromous vs. resident). In the Iberian Peninsula, the southern limit of both species’ distribution, they face different pressures (e.g., barriers, pollution, hydrologica...
Acoustic Telemetry Unravels Movements and Habitat Use Patterns of Juvenile Meag...
Marques, João P.; Almeida, Pedro R.; Moreira, Pedro; Reis-Santos, Patrick; Prista, Nuno; Costa, José L.; Domingos, Isabel; Alexandre, Carlos M.The meagre is among the largest Sciaenidae in the world (max: 230 cm, 103 kg), with a wide distribution range encompassing the NE and CE Atlantic Ocean and the Mediterranean Sea. The life cycle in Atlantic waters includes migratory movements from feeding and overwintering areas at sea to spawning and nursery areas in estuaries and coastal waters. However, significant spawning aggregations are only observed in f...
