New evidence of alternative migration patterns for two Mediterranean potamodrom...
Rato, Ana; Alexandre, Carlos Manuel; Pedro, Sílvia; Mateus, Catarina; Pereira, Esmeralda; Belo, Ana Filipa; Quintella, BernardoIberian barbel (Luciobarbus bocagei Steindachner, 1864) and Iberian nase (Pseudochondrostoma polylepis Steindachner, 1864) are two Mediterranean potamodromous fish species known to perform annual upstream migrations to reach spring spawning grounds. In the Mondego River basin, at the Coimbra dam, migratory movement patterns and individual size structure were assessed through a video recording monitoring system ...
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...

Umbrella review on the possible use of Ivermectin in the treatment of COVID-19
Reis, Mariana; Ferreira, Maria; Pedro, Sílvia; Ferraz Oliveira, Rita; Moreira, FernandoThe urgency to find treatment and prophylactic measures for COVID-19, motivated the use of drugs usually indicated in other pathologies, such as Ivermectin (commonly used as antiparasitic). The main objective of this study was to evaluate the potential use of ivermectin in the treatment of COVID-19, and to identify its mechanism of action and dosing regimen regarding this particular indication. To perform this ...
LIFE Agueda-Gaining Habitat for Migratory Fish in the Vouga River Basin
Pedro, Sílvia; Alexandre, Carlos; Mateus, Catarina; Quintella, Bernardo; Lança, Maria João; Belo, Ana Filipa; Pereira, Esmeralda; Rato, Ana SofiaHabitat loss and overfishing are the most significant threats to diadromous fish, most of them of high socioeconomic and conservationist importance, such as Alosa alosa, Alosa fallax, Petromyzon marinus and Anguilla anguilla. The main objective of the LIFE Águeda project (LIFE16 ENV/PT/000411) is the removal of hydro-morphological pressures towards the reestablishment of conditions for a good ecological status,...
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...
Photosythetic responses of two salt-tolerant plants, Tamarix gallica and Arthro...
Sghaier, Dhouha Belhaj; Pedro, Sílvia; Duarte, Bernardo; Caçador, Isabel; Sleimi, NoomeneIn recent years, the level of arsenic in soil has increased dramatically in many countries, which has raised concern to develop new environmentally friendly techniques to solve problems such as arsenic, which is highly soluble and has toxic effects. It is an environmental issue and a global health matter because of its poisonous and carcinogenic characteristics. It is known that arsenic influenced farmland and ...
Temporal patterns of the catadromous thinlip grey mullet migration in freshwater
Pereira, Esmeralda; Quintella, Bernardo R.; Lança, Maria João; Alexandre, Carlos M.; Mateus, Catarina S.; Pedro, Sílvia; Belo, Ana Filipa; Rato, AnaThe thinlip grey mullet (Chelon ramada Risso, 1827) is a catadromous fish that performs massive migrations to freshwater habitats for feeding purposes that can assume a structuring role on riverine ecology due to the biomass involved in these movements. Seasonal movements of thinlip grey mullet through a vertical slot fish pass located in River Mondego (Portugal) were continuously monitored between 2013 and 201...
Natural recovery of Zostera noltii seagrass beds and benthic nematode assemblag...
Branco, Jordana; Pedro, Sílvia; Alves, Ana S.; Ribeiro, Carlos; Materatski, Patrick; Pires, Ricardo; Caçador, Isabel; Adão, HelenaIn the intertidal seagrass beds of Zostera noltii of Mira estuary (SW, Portugal) the harvesting practices are frequent. The traditional bivalve harvesting not only affects the target species as the remaining biological assemblages. The main aim of this study was to assess the disturbance caused by sediment digging in the recovery of the seagrass beds habitat, through an experimental fieldwork. The responses of ...
