Reproductive traits of the European catfish, Silurus glanis, during the early s...
Gkenas, C.; Sequeira, V.; Ribeiro, D.; Gago, João; Dias, D.; Verma, C.R.; Kumkar, P.; Ribeiro, F.In recent decades, the European catfish Silurus glanis has spread across Europe and elsewhere, significantly impacting the native fauna of the recipient ecosystems. Studies on its reproductive traits from its non-native range are limited, although this is a critical step in developing effective management plans. Here, we explore the reproductive characteristics of invasive European catfish populations in the Lo...

Oliva-Paterna, F.; Olivo del Amo, R.; López-Cañizares, C.; Guillén-Beltrán, A.; Torralva, M.; Anastácio, Pedro; Banha, Filipe; Brandão, PedroThe Spanish and Portuguese societies have a limited understanding of the threats posed by invasive alien species (IAS) in aquatic ecosystems. This gap of knowledge and awareness about IAS problems hampers any policy proposed by administrations and stakeholders, contributing to missing an IAS management strategy. We present the final results, impacts and some learned lessons achieved in the Environmental Governa...

Westwards expansion of the European catfish Silurus glanis in the Douro River (...
Gkenas, C.; Martelo, J.; Ribeiro, D.; Gago, João; Santos, G.; Dias, D.; Ribeiro, F.The current study reports the first occurrence and the spread of the European catfish Silurus glanis (Family: Siluridae) in the Portuguese section of the Douro River, suggesting a potential expansion of its distribution in Portugal either via westward dispersal across international rivers and/or human-assisted introductions into new reservoirs and drainages. The European catfish has unique features (e.g., oppor...

Martelo, J.; Gkenas, C.; Ribeiro, D.; Alves, M.J.; Ribeiro, F.; Cucherousset, J.; Gago, João; Magalhães, M.F.Pool refuges are critical for maintaining stream fish diversity in increasingly intermittent streams. Yet, the patterns and drivers of beta diversity of native and non-native fish in pool refuges remain poorly known. Focusing on Mediterranean streams, we decomposed beta diversity of native and non-native fish into richness difference (RichDiff) and species replacement (Repl), and local (LCBD, LCBDRichDiff and L...
Angler’s preferences, perceptions and practices regarding non-native freshwater...
Banha, F.; Gago, João; Margalejo, D.; Feijão, J.; Casals, F.; Anastácio, P.M.; Ribeiro, F.It is globally recognized that freshwater anglers can have a decisive role in promoting fish introductions. The aim of this study was to analyze fresh water anglers’ actions and perceptions regarding fish introductions, comparing two distinct situations, one with recently arrived non-natives fishes and another with older fish introductions, using the Iberian Peninsula as a case study. To achieve this goal, a bi...

Livro Vermelho dos Peixes Dulciaquícolas e Diádromos de Portugal Continental
Magalhães, M.F.; Amaral, S.D.; Sousa, M.; Alexandre, C.M.; Almeida, P.R.; Alves, M.J.; Cortes, R.; Farrobo, A.; Filipe, A. F.; Franco, A.; Jesus, J.As Listas Vermelhas de Espécies Ameaçadas da União Internacional para a Conservação da Natureza constituem indicadores importantes do estado da biodiversidade, e são amplamente utilizadas para informar e estruturar as atividades de conservação. Estas Listas, publicadas em Livros Vermelhos, resultam de um rigoroso processo de avaliação, baseado num sistema de categorias e critérios de diagnóstico do risco de ext...

Not so much a sea bass: Divergent European sea bass (Dicentrarchus labrax L.) f...
Almeida, Rita; Tanner, S.E.; Mateus, Catarina S.; Ribeiro, F.; Quintella, B.R.European sea bass (Dicentrarchus labrax [Linnaeus, 1758]) is a euryhaline marine migrant fish highly valuable for fisheries and aquaculture. Although juveniles are known to use estuaries and occasionally move to freshwater environments, these freshwater incursions had not been reported for adults. Recently, this behavior was observed in the Tagus River (Portugal) for adults occurring up to 150 km from the river...
