  • CIÊNCIAVITAE will substitute previous FCT platforms

    CIÊNCIAVITAE is a unique, personalized, simple, harmonized and structured curriculum that gathers the information that is presently dispersed in multiple platforms, as FCT-SIG CV, DeGóis, RENATES, REBIDES, ORCID and RCAAP.  Existing platforms will be discontinued by phases and CIÊNCIAVITAE will be fully operational in 2021. After 1 mar 2018 you will not be able to create new curricula and after 1 Jul 2018 the access to edit your curriculum will also end. FCT provides several support and tutorials that help you in the process of transition between platforms.

  • DBio & CESAM´s PhD graduated publishes on Science about changes in biodiversity

    Laura Antão graduated by the University of Aveiro and the University of St Andrews, under the supervision of Dr Maria Dornelas and Professor Amadeu Soares, and currently a postdoctoral researcher at the University of Helsinki, published in the high impact journal Science under BDio&CESAM´s affiliation. The work is about the rapid change on biodiversity driven by climate change and other human influences. The team analysed the global patterns in temporal change in biodiversity using a large quantity of time-series data from different regions (the data include many different ecosystems across continents and cover the marine, terrestrial and freshwater realms (BioTIME database*)). Their findings reveal clear spatial patterns in the rates of richness and composition change, where marine taxa exhibit the highest rates of change. The marine tropics, in particular, emerge as hotspots of species richness losses. Given that human activities are affecting biodiversity in magnitudes and directions that differ across the planet, these findings will provide a much needed biogeographic understanding of biodiversity change that can help to inform conservation prioritization." * citation: Dornelas M, Antão LH, Moyes F, Bates, AE, Magurran, AE, et al.

  • Wilder spoke with José Alves, CESAM researcher, about the Montijo Airport and its consequences for the population of birds

    In early November, Wilder went to Estuário do Tejo to see how thousands of birds could be affected by the new airport (Montijo). Wilder spoke with José Alves, researcher at CESAM, who has been studying migratory birds from Estuário do Tejo for 15 years. Full news here, but only in portuguese.

  • CESAM gets funding to study cockles

    Although they play a crucial role in the ecosystem and its importance in the economy of the coastal zones and the region, the cockle is an illustrious unknown to science towards its distribution, evolution and health of its populations in Ria de Aveiro. Therefore, the COACH project - “A cooperative approach applied to the conservation and management of cockles” was one of three funded by the Oceans Conservation Fund. The COACH project, coordinated by Luísa Magalhães, aims to collect multifactorial information on cockle fishing, its biology and the physical-chemical characteristics of the places where it occurs.

  • Study from CESAM researchers - 'Striped dolphins as trace element biomonitoring tools in oceanic waters: Accounting for health-related variables' was published on 'Science of the Total Environment' journal

    In Europe, monitoring contaminant concentrations and their effects in the marine environment is required under the Marine Strategy Framework Directive (MSFD, 2008/56/EC). The striped dolphin (Stenella coeruleoalba) is the most abundant small cetacean species in Portuguese oceanic waters, representing a potential biomonitoring tool of contaminant levels in offshore waters. Concentrations of nine trace elements were evaluated by ICP-MS in kidney, liver and muscle samples of 31 striped dolphins stranded in the Portuguese continental coast. The mean renal Cd concentration was high (19.3?μg.g−1 wet weight, range 0.1–69.3?μg.g−1 wet weight) comparing to striped dolphins from other locations. Therefore, the present study reports a possibly concerning level of Cd in the oceanic food chain in Portuguese offshore areas. This study also aimed at evaluating potential relationships between trace element concentrations and striped dolphins' biological and health-related variables. Individual length was related with some of the trace element concentrations detected in striped dolphins. Indeed, Cd, Hg and Se bioaccumulated in larger animals, whereas the reverse was observed for Mn and Zn. Striped dolphins with high parasite burdens showed higher levels of Hg, while animals showing gross pathologies presented higher concentrations of Cd and Se. This study reported relationships between trace element concentrations and health-related variables for the first time in striped dolphins and it also provided information on the relative contamination status of Portuguese oceanic waters in comparison to other regions in the world. https://www.sciencedirect.com/science/article/pii/S0048969719344018?via%3Dihub
