15 pages, 6 figures, 4 tables ; Population dynamics, morphology, density, lipid contents and prey capture rates were studied in a patchy population of the tree-like passive suspension feeder Eudendrium racemosum (Cnidaria: Hydrozoa) during seasonal cycles. Density and size of colonies oscillated due to intraspecific competition (following the self-thinning rule) and predation (nudibranchs) showing size distributions in which alternatively large-and small-sized colonies were more abundant. Increase in the trophic impact on the water column was correlated with colony size (30.7 mg C m -2 d -1 in late spring-early summer compared with 10.2 mg C m -2 d -1 in the rest of the year). Lipid accumulation in the hydrocauli followed the same trend, being higher during the reproductive period (140 μg lipids mg -1 organic matter [OM]) compared with the rest of the year (70 μg lipids mg -1 OM). The short time cyclic variations reproduce, in a short time scale, the variations studied in other benthic suspension feeders, suggesting E. racemosum as a model organism to better understand the importance of large colonies in long-lived species in benthic-pelagic coupling processes. The accordance with the self-thinning rule found for this animal species strengthens the animal forest concept (a 3-dimensional live structure composed mainly by heterotrophic organisms such as gorgonians, bryozoans, and sponges), confirming the validity of the utilization, by marine ecologists, of the conceptual tools developed for terrestrial forest sciences. It is suggested that the impact of mature populations on benthic-pelagic coupling and biogeochemical cycles, simulated for long-lived species, could be validated by studying fast-growing species, in order to understand the importance of the preservation of complex structures and long-lived eco-engineering organisms in benthic habitats. © Inter-Research 2012 ; Support for this work was provided by a FPI fellowship from the 'Ministerio de Educación y Ciencia' and a Ramón y Cajal Contract (RyC-2007-01327) to S.R., by a CICYT grant and by the MAST-III-ELOISE European Union METRO MED Project.

The aim of this workshop was to ask potential end-users of the citizens' information pack on legal and ethical issues around ICTs (i.e. citizens and citizens' groups) the following questions: What is your knowledge of the EU's General Data Protection Regulation (GDPR), and what actions have you taken in response to these regulations? What challenges are you experiencing in ensuring the protection and security of your project data, and compliance with the GDPR, within existing data management processes/systems? What information/tools/resources do you need to overcome these challenges? What are the best formats/channels for receiving, sharing and acting upon this information? What is the most appropriate structure/format(s) for the citizens' information pack?

ICTs, personal data, digital rights, the GDPR, data privacy, online security… these terms, and the concepts behind them, are increasingly common in our lives. Some of us may be familiar with them, but others are less aware of the growing role of ICTs and data in our lives - and the potential risks this creates. These risks are even more pronounced for vulnerable groups in society. People can be vulnerable in different, often overlapping, ways, which place them at a disadvantage to the majority of citizens; Table 3 in this guide presents some of the many forms and causes of vulnerability. As a result, vulnerable people need greater support to navigate the digital world, and to ensure that they are able to exercise their rights. This guide explains where such support can be found, and also answers the following questions: What are the main ethical and legal issues around ICTs for vulnerable citizens? Who is vulnerable in Europe? How do issues around ICTs affect vulnerable people in particular? This guide is a resource for members of vulnerable groups, people who work with vulnerable groups, and citizens more broadly. It is also useful for data controllers who collect data about vulnerable citizens. While focused on citizens in Europe, it may be of interest to people in other parts of the world. It forms part of the Citizens' Information Pack produced by the PANELFIT project, and is available in English, French, German, Italian and Spanish.
