Distribution of skates and sharks in the North Sea: 112 years of change [PDF]
, 2016 How have North Sea skate and shark assemblages changed since the early 20th century when bottom trawling became widespread, whilst their environment became increasingly impacted by fishing, climate change, habitat degradation and other anthropogenic ...

The influence of rivers on seabird foraging ecology
Biological Reviews, EarlyView.ABSTRACT Rivers act as vital arteries to the world's oceans, delivering fresh water and nutrients that sustain marine ecosystems. Globally, river flow increasingly is being altered by climate change and anthropogenic pressures; yet the significance of rivers to predatory marine species, such as seabirds, and the extent to which river‐related changes ...

Effects of Trawling on Seamounts [PDF]
Oceanography, 2010 Trawling involves the towing of nets through the water or along the seafloor to sieve out fish and marine invertebrates. It is the most widely used method to catch fish throughout the world, and there are many variations in gear design and towing methods.
