Invasions in aquatic systems: Patterns, mechanisms and management
Anastacio, P.; Ribeiro, F.; Chainho, P.The 13th NEOBIOTA International Conference on Biological Invasions (NEOBIOTA 2024), held in Lisbon, Portugal, from 3–6 September 2024, brought together 421 participants from 47 countries for one of the most significant global gatherings in invasion science. Notably, this meeting featured the strongest representation of aquatic studies to date, spanning marine and freshwater systems across oral sessions, posters...
Outcomes of the LIFE INVASAQUA project: An integrated approach for the preventi...
López-Cañizares, C.; Olivo del Amo, R.; Guillén-Beltrán, A.; Torralva, M.; Anastacio, P.; Banha, F.; Brandão, P.; Barca, S.; Cobo, F.; Vieira-Lanero, R.Invasive alien species (IAS) pose a growing threat to biodiversity, ecosystem services and human well-being, particularly in aquatic ecosystems worldwide. These species lead to severe environmental and economic impacts by altering habitats, disrupting ecological processes and outcompeting native species. In the Iberian Peninsula, IAS represent a major risk to its unique freshwater and estuarine ecosystems, whic...
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...
Behaviour of the apex predator European catfish (Silurus glanis) on a recently ...
Santos, G.S.; Ribeiro, F.; Pereira, E.; Silva, A.F; Almeida, P.R.; Ribeiro, D.; Quintella, B.R.The European catfish (Silurus glanis L.) is a large, non-native, invasive freshwater species known for its high fecundity, long lifespan and significant predatory potential, possibly threatening native fish communities. While some studies exist on its spatial use, most focus on its native range and lack detailed circadian and annual activity patterns. This study uses acoustic biotelemetry to track 10 adult fish...
LIFE INVASAQUA - AQUATIC INVASIVE ALIEN SPECIES OF FRESHWATER AND ESTUARINE SYS...
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...

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 actions, main results and some learned lessons achieved in the Environmental Governan...
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...
DNA metabarcoding reveals the diet of the invasive fish Oreochromis mossambicus...
Nogueira, S.; Curto, M.; Gkenas, C.; Afonso, F.; Dias, D.; Heumüller, J.; Félix, P. M.; Silva De Lima, Rivete; Chaínho, P.; Brito, A. C.; Ribeiro, F.Invasive species can trigger profound effects on recipient ecosystems, namely through the food web. Despite being recognized as one of the worst invasive species, little is known about the feeding ecology of the Mozambique tilapia Oreochromis mossambicus. To understand how this invasive species might impact food webs, we applied metabarcoding to analyze its diet’s composition in two African mangroves, in the Ob...
