“…Factors such as the NAO (albacore, Arregui et al 2006;sardine, Alheit & Hagen 1997; several fish stocks, mammals and seabirds, Hemery et al 2008), EA pattern (anchovy, Borja et al 2008); temperature anomaly (hake, Fernandes et al 2010), upwelling strength (anchovy, Borja et al 2008), turbulence (anchovy, mackerel and hake, Borja et al 1998, Allain et al 2007, Fernandes et al 2010, river discharge (anchovy, Planque & Buffaz 2008) and Ekman transport (anchovy, Irigoien et al 2008) have been shown to have significant effects on the recruitment or abundance of these species.…”

“…On the other hand, using robust supervised classification methods, as applied to fish recruitment (Fernandes et al 2010), prediction of the summer Gelidium corneum biomass was attempted, taking into account sun hours, waves, winds, NAO andEA. Data from 1993-2009 showed that EA and sun hours are the factors which best explain the variability in the summer biomass.…”

The impacts of global climate change on the Basque coast and the pelagic systems within the southeastern Bay of Biscay are reviewed. Climate projections under greenhouse gas emission scenarios indicate that this area will experience changes in climate throughout the 21st century, including warming of surface air (especially heat wave episodes), intensification of extreme daily rainfall (10%), warming of the upper 100 m of the ocean layer (1.5 to 2.05°C), and sea level rise (SLR; 29 to 49 cm). Observations made in the bay throughout the 20th century for air temperature and mean sea level are in agreement with these projections. Trends in ocean-climatic historical observations within the area, including sea temperature, precipitation, upwelling/downwelling, turbulence and wave climate, are also reviewed. The main impacts on the coast are expected to be from SLR, especially in low-lying areas (mostly urbanised) within estuaries. Sandy beaches are also expected to undergo significant mean shoreline retreats of between 25 and 40% of their width. As the sea level rises, the natural migration of saltmarshes and intertidal seagrasses landward will be constrained, in most cases, by existing anthropogenic fixed boundaries. Empirical relationships between the distribution and dynamics of the long-term biological measures (plankton, primary production, benthos, and fisheries) on the one hand, and ocean-climatic variability on the other, indicate that pelagic and coastal water ecosystems will be affected by ocean warming, increased stratification, shifts in anomaly patterns and streamflow regimes. The largest uncertainties are associated with the lack of downscaled projections within the bay on ocean circulation, ocean-meteorological indices, wave climate and ocean acidification.

Vulnerabilidade de pescadores no litoral sul do Brasil e sua relação com áreas marinhas protegidas em um cenário de declínio da pescaABSTRACT: Vulnerability of small-scale fishers in the north coast of Paraná State, Southern Brazil, has been increasing due to a decline in catches and general problems of access to and management of natural resources, associated with biodiversity conservation policies. The predicted effects of climate change will represent an additional source of disturbance on local livelihoods. This study aimed to describe vulnerability of fishers and their adaptation strategies to ongoing reductions in catches, considered an analogue of possible responses to expected effects of climate change, and to evaluate the influence of no-take protected areas on them. Interviews were applied to 213 households, in 9 villages from Guaraqueçaba, in the Paranaguá Estuarine Complex. Results show that vulnerability varies in different spatial levels, mainly due to differences in the reliance on fisheries as a source of income, and in distribution of physical and social capital. Protected areas, if not adequately managed, can have a double negative effect on more vulnerable households, by restricting their access to mangrove resources in the present, and by limiting the viability of their favoured adaptation strategy for the future. These results are potentially useful for the development of biodiversity conservation and fisheries management actions adequate to the local level, and that contribute to reduce inequality and build resilience of fishers and the coastal ecosystems they rely on, in a scenario of declining fisheries and climate change.

Abstract. In this paper we propound the use of a number of entropybased metrics and a visualization tool for the intrinsic evaluation of Sentiment and Reputation Analysis tasks. We provide a theoretical justification for their use and discuss how they complement other accuracybased metrics. We apply the proposed techniques to the analysis of TASS-SEPLN and RepLab 2012 results and show how the metric is effective for system comparison purposes, for system development and postmortem evaluation.
