“…How these differences in diet influence species susceptibility, adaptability and conservation remains an open question and it is crucial to understand how fin whales respond to changes in prey availability, as well as how prey is affected by changing environmental conditions (Víkingsson et al, 2015). The potential effects of global environmental changes on Mediterranean fin whales may influence the entire population, with virtually no space to move to northern latitudes (Evans et al, 2010). 15 N values were previously investigated in baleen plates from fin whales sampled off Ireland (n ¼ 7) (Ryan et al, 2013) and from the Mediterranean Sea (n ¼ 9) (Bentaleb et al, 2011).…”

a b s t r a c tThe fin whale (Balaenoptera physalus) is the most abundant and widespread mysticete species in the Mediterranean Sea, found mostly in deep, offshore waters of the western and central portion of the region. In the Mediterranean, this species is known to feed mainly on krill, in contrast to its Atlantic counterpart, which displays a more diversified diet. The International Whaling Commission recognizes several managements units in the Atlantic and the Mediterranean Sea and the connectivity between these populations is still being debated. Questions remain about inter-individual feeding strategies and trophic ecology.The goal of this study was to compare isotopic niches of fin whales from the Mediterranean Sea and the Celtic Sea (North Atlantic). One could indeed expect that species displaying narrow niches would be more susceptible to ecosystem fragmentation and other anthropogenic impacts.

“…It is the most abundant cetacean species in the North Sea region (Hammond et al 2008) and its abundance on the European Atlantic continental shelf was estimated to be around 375,000 in 2005 (Hammond et al 2013). In the shallow southern North Sea the number of harbour porpoises appears to have increased since the early 1990s (Hammond et al 2002;Camphuysen 2004;Camphuysen and Peet 2006;SCANS II 2008), however, although still common, numbers in the northern North Sea have declined (SCANS II 2008;Øien 2010;Evans and Bjørge 2014). The reasons for this are not known, but a major distributional shift appears to have taken place from the north-western North Sea in 1994 to the south-western part in 2005 (Hammond et al 2002(Hammond et al , 2013Fig.…”

North Sea Region Climate Change Assessment

This chapter presents a review of what is known about the impacts of climate change on the biota (plankton, benthos, fish, seabirds and marine mammals) of the North Sea. Examples show how the changing North Sea environment is affecting biological processes and organisation at all scales, including the physiology, reproduction, growth, survival, behaviour and transport of individuals; the distribution, dynamics and evolution of populations; and the trophic structure and coupling of ecosystems. These complex responses can be detected because there are detailed long-term biological and environmental records for the North Sea; written records go back 500 years and archaeological records many thousands of years. The information presented here shows that the composition and productivity of the North Sea marine ecosystem is clearly affected by climate change and that this will have consequences for sustainable levels of harvesting and other ecosystem services in the future. Multi-variate ocean climate indicators that can be used to monitor and warn of changes in composition and productivity are now being developed for the North Sea.

“…DT (Detection Threshold) is the signal-to-noise ratio necessary and the target signal is a function of the receiver. Acoustic science is highly developed in dolphins; previous researchers have emphasized the recording and analysis of vocalization [6][7][8][9][10]. Research of bioacoustics is needed to be able to know language of communication (Acoustic communication) in mammals.…”
