Conference Paper
Estuaries have the particularity of being in constant change concerning the salinity of the water, since the river carries fresh water to the mouth, while the force of the tide pushes salty water upstream, reaching several kilometers upstream given the right conditions. These bodies of water do not mix instantly, allowing the appearance of a distin...

Background: Amphipods are one of the most diverse and widely distributed groups of crustaceans, often constituting dominant or key elements of marine and coastal communities. As with many other marine invertebrate taxa, rigorous species identifications can be rather challenging, and cryptic species reports have been increasing. In this study we com...
Presentation
Background: The estuarine and coastal intertidal areas have a large number of benthic invertebrates, where the annelid polychaetes are one of the most representative classes and, therefore, important indicators of environmental quality in these ecosystems. Yet, these organisms have been poorly studied, in comparison to other taxa of similar ecologi...
Article
Annelid polychaetes have been seldom the focus of dedicated DNA barcoding studies, despite their ecological relevance and often dominance, particularly in soft-bottom estuarine and coastal marine ecosystems. Here we report the first assessment of the performance of DNA barcodes in the discrimination of shallow water polychaete species from the sout...

Project
The EcOffshoreBE project´s main goal is the creation of a joint R&D Unit between CiviTest (the project leader) and University of Minho (UMinho), represented by its Departments of Biology, Industrial Electronics, Polymer Engineering and Civil Engineering. This new collaborative framework aims at reinforcing the internal R&D competences of both CiviTest and UMinho for the future, post-project, development of high-performance cement-based materials (more durable and eco-sustainable) for energy production offshore maritime structures. By setting a medium/longterm strategic partnership, these entities purport to gather the adequate/necessary conditions for the joint planning of projects (to be carried out outside of EcOffshorBE's scope) that will allow the development of new products and significant scientific and technological advances, leveraged by this project?s sharing, mobility and exchange of resources between both entities, as well as transfer and sharing of technology and knowledge. Particularly, the R&D Unit will study the problems associated with maritime environmental exposure of concrete in offshore structures (especially wind farms). The decrease in its mechanical resistance, derived from physical-chemical phenomena taking place on its micro-structure, leads to the shortening of its lifecycle demanding high maintenance costs, limiting, thusly, its competitiveness. This situation limits the most desired exploitation of the potential of offshore energy production (e.g., offshore windfarms), an area of most special interest for the smart specialization of the County and the Northern Region in particular.
Project
The Museu da Água ao Ar Livre do Rio Vez was conceived to promote and enhance the richness and diversity of the cultural and environmental heritage associated with nature, the Vez river and to the associated human activity. Being an open-air museum, the visitor has the opportunity to be in direct contact with nature, appreciating the faunistic and floristic diversity associated with the river. The visitor can also discover many traces of high historical, architectural, ethnographic value left throughout the history of the region.
