The first Mares Conference on Marine Ecosystems Health and Conservation was a successful event organized by the MARES doctoral programme bringing together over 150 researchers in Olhão, Portugal from November 17th to 21st 2014. The conference was opened by Prof. Dr. Hans-Otto Pörtner, whose keynote address focused on a sectoral analysis by the Intergovernmental Panel on Climate Change Fifth Assessment Report (IPCC AR5) on the impacts of climate change on the world’s oceans. The first session on “Future oceans” was opened with a talk by Dr. Frank Melzner highlighting the problems calcifying invertebrates face in the warmer, more acidic and hypoxic waters. Other presenters dealt with changing global diversity patterns, ocean acidification, and the loss the genetic diversity. The second session on “Natural resources” was opened by Dr. Rainer Froese, who focused on whether or not the oceans can feed humanity. This talk introduced other contributions in the session, dealing with fisheries issues and Marine Protected Areas, as well as problems with proper identifications of species used for economic purposes. “Biodiversity effects” was the scope of the third session opened by a talk on oxygenation and marine biodiversity challenges in the 21st Century by Prof. Lisa Levin. Rapid ocean deoxygenation is a process which is currently less investigated but which has considerable effects on body size, taxonomic composition, habitat heterogeneity, and nutrient cycling. The following presentations focused on other factors having a strong effect on marine biodiversity, ranging from the harvesting of algae to the fragmentation of ecosystems. The fourth session addressed “Biological invasions”. Dr. Gregory Ruiz discussed biological invasions in North American marine ecosystems and the need for constant monitoring, and the use of a dynamic and multi-vector approach. Problems with invasive species in European waters were addressed with examples from the Baltic Sea, the North Sea, and the Mediterranean Sea. The fifth session on “Ocean Noise” was opened by Prof. Peter Tyack with a talk on the effects of anthropogenic sound on marine mammals. Although ocean noise issues are often linked to marine mammals, the effects of sound related to marine constructions on fish behaviour, nicely illustrated that ocean noise is a factor with a much broader impact than expected. The last session of the first Mares Conference dealt with “Habitat loss”. Dr. Michael Beck focused on this topic with his talk on ‘Building Coastal Resilience for Climate Adaptation and Risk Reduction’. Talks in the session ranged from the use of telemetry as a tool to monitor species in changed habitats, to cases dealing with sea level rise related problems in for example salt-marshes. The first Mares Conference offered a broad range of oral and poster presentations, as well as digital presentations. The poster and digital object presentations included over 100 contributions.

Comparisons between terrestrial and marine ecosystems are generally not in the main stream of scientific literature even though Webb (2012) listed several points for which the transfer of knowledge and concepts related to one or to the other system would benefit our understanding of both. Even sharing this view, the leading hypothesis behind this contribution is that the pelagic system, where the dominant biotic component by number and biomass is microscopic, has specific features which strongly differentiate it from the above-the-surface terrestrial systems. Due to this, climate change, i.e. changes in temperature, precipitation and most importantly in the dynamics of the two fluid media, atmosphere and ocean, act with different mechanisms which prevents proceeding with analogies in many cases. In addition, the non-linearity of most of the processes and responses to perturbations requires, in order to obtain reliable forecasts or hindcasts, a detailed analysis of the path followed by the system which is normally overlooked in the step-change simulations or projections.
