“…Studies carried out by Dr. Manuel Contreras-Lopez and colleagues (Universidad de Playa Ancha, Valparaíso) in central Chile (ca. 33° S), demonstrate 0.5ºC increase in terrestrial temperatures during the last 50 years, 10% reduction of rainfall, and a sea level rise of 3.3 mm year -1 , which is concomitant with the increased occurrence of extreme climatic events such as storm surges affecting the geomorphology and wetlands along the coast (Contreras-López et al 2016;Martínez et al 2017;Carvajal et al 2017). Furthermore, the importance of tidal variability in coastal wetlands was emphasized in the workshop by Dr. Mario Pino (Universidad Austral de Chile).…”

A Workshop on Coastal Wetlands of Chile was held at Universidad Austral de Chile (Valdivia. november 2017). It was discussed the impact of earthquakes and tsunamis along this coast and their implication for wetlands. These events produce major modifi cations associated with variable rates of resilience. Emphasis was placed on social dimensions of such disturbances considering their impact on ecosystem services. Societal resilience must be included within the scales of wetland recovery, and incorporated in conservation and management strategies.

“…Either way, any future attempts to carry out in situ behavioural studies will have to improve the methodological logistics and explore, or develop, statistical methods which better suit the data, possibly leading to more generalized conclusions. Although the data presented in this study about the influence of wind-induced turbulence on fish schools will set a basis for studying the future of rocky reef fishes, especially taking into account the recent increase in extreme coastal storms, which erode the coasts of central Chile (Martínez et al 2018). Also, in future studies, this oceanographic influence on fish larval behaviour ought to unveil its impact beyond the pelagic larval stage, as well as its carry-over effects on fitness and the dynamics of juvenile and adult populations.…”

This study evaluates the swimming behaviour of pre-settled fish larvae of the triplefin Helcogrammoides chilensis (Tripterygiidae) in relation to local environmental conditions. Larval aggregations were recorded on rocky reefs off central Chile during the austral summer of 2014 and 2016 to describe their swimming behaviour (i.e. solitary, shoaling, schooling) and relate it to in situ water temperature, wind stress, wind speed and turbulence. Shoaling and solitary behaviour were influenced only by wind-induced turbulence in 2014 and by seawater temperature and wind stress in 2016. Schooling behaviour was not influenced by any of the environmental variables. In situ swimming behaviour of fish larvae has been little investigated, and this work proposes a non-invasive in situ methodology for studying fish larval behaviour.

“…These natural events occur on various spatial and temporal scales, being influenced by many factors, such as wind, waves and nearshore currents. Moreover, it is expected that climate change will have a negative impact on coastal areas in the future, with sea levels being supposed to rise and the marine conditions becoming more aggressive [7][8][9].…”

The aim of the present work is to provide an overview of the possible implications involving the influence of a generic marine energy farm on the nearshore processes. Several case studies covering various European coastal areas are considered for illustration purposes. These include different nearshore areas, such as the Portuguese coast, Sardinia Island or a coastal sector close to the Danube Delta in the Black Sea. For the case studies related to the Portuguese coast, it is noted that a marine energy farm may reduce the velocity of the longshore currents, with a complete attenuation of the current velocity for some case studies in the coastal area from Leixoes region being observed. For the area located close to the Danube Delta, it is estimated that in the proposed configuration, a marine energy farm would provide an efficient protection against the wave action, but it will have a relatively negligible impact on the longshore currents. Summarizing the results, we can conclude that a marine energy farm seems to be beneficial for coastal protection, even in the case of the enclosed areas, such as the Mediterranean or Black seas, where the erosion generated by the wave action represents a real problem.
