New evidence of alternative migration patterns for two Mediterranean potamodrom...

Iberian 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 ...

Parallel evolution despite low genetic diversity in three-spined sticklebacks

When populations repeatedly adapt to similar environments they can evolve similar phenotypes based on shared genetic mechanisms (parallel evolution). The likelihood of parallel evolution is affected by demographic history, as it depends on the standing genetic variation of the source population. The three-spined stickleback (Gasterosteus aculeatus) repeatedly colonized and adapted to brackish and freshwater. Mo...

Living on the edge: parasite communities of three-spined stickleback fish popul...

This study involved collecting parasite data from populations inhabiting the most southern end of the species distribution in the North Atlantic (i.e., Portugal), aiming to understand the di erences in parasite community associated with the populations that persist at such low latitudes.

Investimento na promoção e sustentabilidade dos recursos piscícolas da região C...

Com o objetivo de resolver alguns dos problemas identificados e desenvolver avanços técnicos e científicos que permitam otimizar o sucesso destas ações de repovoamento, foi, em 2018, dado início ao projeto “CRER - Adaptação do Posto Aquícola de Campelo para a Criação Experimental de Trutas Assilvestradas”, uma operação cofinanciada por Fundos Europeus (FEAPM - Fundo Europeu dos Assuntos Marítimos e das Pescas),...

The decline of the ecosystem services generated by anadromous fish in the Iberi...

This 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...
