In Algae We Trust. That might just as well have been the subtitle of this book. In Slime (published in the UK as Bloom, but I read the US version), author Ruth Kassinger writes of the many fundamental, often eye-opening roles that algae play in our ecosystems. But she also travels around the world to talk to farmers, scientists, and inventors. From food to plastics to fuel, entrepreneurs are discovering that these little green powerhouses hold immense biotechnological potential.
The Southern Ocean, that vast body of water that flows unhindered around Antarctica, has to be one of the most forbidding oceans on our planet. Its latitudes are referred to by increasingly unnerving names the gale-force winds that have terrorised mariners since they first set sail here – the roaring forties, the furious fifties, the screaming sixties. Its waters are so cold that they are actually below freezing in places, with only their salinity preventing them from freezing solid (fish here have evolved antifreeze proteins!) As a consequence of these extreme conditions, this region has long remained unexplored. But, as historian Joy McCann shows, explore it we did. Brace yourself for a gripping piece of environmental history, marked by heroism as much as hubris, and curiosity as much as cruelty.
What does the deep ocean make you think of? An alien world right on our doorstep? The cradle of life? A global garbage dump? The lungs of the planet? Or the world’s most abused ecosystem? If I am to believe marine biologist Alex Rogers, the deep ocean is all of the above, and so much more. With three decades of research experience and scientific consultancy credits for the BBC series Blue Planet II under his belt, he knows what he is talking about and he knows how to talk about it. The Deep is an intensely captivating and urgent book that swings between wonder and horror.
Sea otters don’t eat algae. And yet, their diet influences the abundance of seaweed. How? Indirectly. Sea otters eating sea urchins (spiky animals in the same class as sea stars) eating kelp has become a textbook example of a trophic cascade, and Serendipity is a first-hand account by ecologist James A. Estes of how this happened. A trophic cascade refers to the indirect effects that ripple through a food web as a result of, for example, a predator consuming its prey. Simultaneously, the book is a searingly open account of how science is done, how ideas change, and how fortuitous events can suddenly send your research programme off in a whole new direction.
The problem with many history books is that they are written long after the facts, sometimes when the original protagonists are no longer alive. Historians or journalists often have no choice but to puzzle together the pieces of their story from eyewitness testimony or archival sources. Kin: How We Came to Know Our Microbe Relatives is a welcome exception to this rule. Written by emeritus microbiology professor John L. Ingraham, currently 94 years young, this book gives an intellectual history of the discipline of microbiology based on over seven decades of first-hand involvement and observation.
American author Paul Greenberg has written two previous books about (eating) fish (American Catch: The Fight for Our Local Seafood and Four Fish: A Journey from the Ocean to Your Plate), so he is no stranger to the rather, errr, fishy topic of omega-3 fatty acid supplements. His new book, The Omega Principle, is much more than just a critique of the supplement industry though. This engagingly written reportage digs far deeper, asking where this oil comes from, and reports on that vast segment of the global fishing industry known as the reduction industry, and a food system out of whack with our needs.
Krill is one of those enigmatic invertebrate groups that feeds whole ocean ecosystems but remains itself little known. Even to a biologist such as myself (who has studied fish for crying out loud!), these critters are largely a set of question marks. I mean they are crustaceans, swim in the sea, are numerous and… oh look, a blue whale!
