Plankton as indicators of ecosystem change
studying the plankton has helped to understand climate-induced changes in the North Sea, a productive marine ecosystem that once provided 5% of the total global seafood harvest.

Whales, dolphins and porpoises, collectively known as cetaceans (for their classification in the mammalian order Cetacea) have long captured the attention of humans. From early drawings etched on the walls of Paleolithic caves, to 21st century satellite tags tracking the underwater movements of these denizens of the deep, the lives of humans and whales have been inexorably entangled.

We have come a long way since early conservationists started with many beleaguered nesting sea turtle populations in the middle to the late part of the 20th Century. Nesting turtles are now protected in many countries around the world, there are now very few large legal harvests, and many populations, such as the one we study in Ascension Island have begun to recover incredibly well.

The dark, cold, crushing depths of one of the world’s largest ecosystems is home to about half of all known shark species. However, living at depths between 200-3000m, these deep-sea species aren’t your typical sharks. Armed with sharp defensive fin spines, large reflective eyes, and, in some cases, an ability to glow in the dark, these alien sharks could be the stars of a science fiction horror movie.

The Moray Firth and North East coast of Scotland are home to a resident population of bottlenose dolphins, around 200 or so in number and I am fortunate to spend my working life studying and photographing these big, charismatic predators.

In the sea, the plankton begin the marine food chain. Without plankton there wouldn’t be polar bears on the ice.

Over the coming weeks Blue Planet Society needs your help to highlight the availability of wild marine animals in supermarkets, fishmongers and fish markets across the globe by posting your photographs on social media using the hashtag #Wildlife4Sale.

At a time when the Australian conservation movement faces great challenges, a protected seabird species in decline was consumed for novelty value on British reality TV show ‘I’m A Celebrity…Get Me Out Of Here!’ (Nov 22nd) in Murwillumbah, New South Wales.
