In a new article, a researcher from CIMA (Erwan Garel) describes a new analytical approach to analyse tidal propagation along estuaries in function of variable forcing conditions at the mouth (e.g., tidal amplitude). Applied at the Guadiana Estuary, the method provides direct insights about neap-spring variations resulting from the relative effects of friction, morphologial convergence and wave reflection at the estuary head.

Two members of CIMA, M. Bebianno and Thiago Rocha published the article “Changes in metallothione in transcription levels in the mussel Mytilus galloprovincialis exposed to CdTe quantum dots” recently in the Ecotoxiclogy journal. Quantum dots are fluorescent metal nanoparticles, which have a cadmium core and due to their optical properties have various biomedical, industrial and commercial applications. However, their metabolism and detoxification processes when accumulated in marine invertebratesthe hazards that these particles may have for human healthare still poorly understoodThe work now published evaluates the accumulation of these nanoparticles in marine bivalves (the mussel) and confirms the relevant role of metallothionines and the transcription of the MT10 and MT20 genes in the process of detoxification of quantum dots, nanoparticles of Cd and tellurium when accumulated in mussels

The exposure of mussels to metallic nanoparticles of cadmium (Quantum dots) induces changes in the metallothionein gene (mt20IV) indicating a specific response of this gene in the metabolism and a protection against oxidative stress caused by the accumulation of Quatum dots in mussel tissues. These results are presented in the publication "Changes in metallothionein transcription levels in the mussel Mytilus galloprovincialis exposed to CdTe quantum dots" by Thiago Lopes Rocha, Eider Bilbao, Cátia Cardoso, Manu Soto and Maria João Bebianno published online in the journal Ecotoxicology.
Portugal has been losing many plant fossils that have been taken by researchers from other countries abroad. The complaint is made by a paleontologist from CIMA, University of Algarve. The Portuguese law does not provide the protection of this kind of heritage. There are Portuguese fossils to be taken to other countries.

The University of Algarve (UAlg) and the Centre of Marine and Environmental Research (CIMA) organised a International Conference "Sustainable Development of the Oceans: A Useful Utopia: A Useful Utopia" in honour of Professor Mario Ruivo,  last 14th and 15th of November (Green auditorium, University of Algarve). The objective was "to evoke the contribution of this marine biologist, an honorary doctor of UAlg, for the development of marine sciences and technologies, with notable impacts at national and international levels."
The initiative also had the support of the EurOcean Office and the following research centres: CIIMAR (University of Porto), CESAM (University of Aveiro) and MARE (several Portuguese universities).

 

Doctor Sónia Cristina was awarded a Prize in Sciences on 02/10/2017 at a ceremony at the Algeciras Campus of the University of Cadiz. The PhD thesis of Sónia won the second prize for the best thesis of the year from the University of Cadiz.
