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.
From Skeletor to the Danse Macabre, from Army of Darkness to ossuaries and holy relics – despite being largely hidden in life, skeletons are some of the most recognizable structures that nature has produced. Science writer Brian Switek has written a sizzling little book with Skeleton Keys* that delves into both the biological and cultural significance of human bones, showing them to be more than just a powerful reminder of death and mortality.
One fond memory I have of studying biology at Leiden University in the Netherlands was a behind-the-scenes tour for first-year students at the then brand new location of Naturalis Biodiversity Center. This included a tour of the main tower housing the scientific collection normally off-limits to the general public. This is the domain of the museum curator, but their work involves much more than spending time amidst storage cabinets. To get a good idea just how diverse this job is, look no further than this lively and beautifully presented memoir. Here, Lance Grande tells of his career of more than thirty years as a curator at the Field Museum in Chicago.
Communicating the complexities and abstractions of scientific findings is not easy. Anyone who has ever slogged through yet another dense paper or muddled presentation will acknowledge this. Our universe, it seems, cares not for the human quest of understanding it. One of the things, then, that makes popular science books such a treat is that they infuse scientific findings and speculation with a certain lyricism and good storytelling. This is why we flock to authors such as Nick Lane, Richard Dawkins, Richard Fortey, and many others besides. This is why Richard Feynman and Carl Sagan remain household names decades after their death. The latter’s Pale Blue Dot segment still gives me goosebumps. With Evolutions: Fifteen Myths That Explain Our World, science historian Oren Harman boldly turns the concept on its head: rather than bringing poetic flair to a pop-science book, he brings scientific flair to an epic poem.
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.
Beetles do it. As do fish. And squid, sharks, jellyfish, salps, dinoflagellates, and a host of other invertebrates. Bioluminescence, the production of light by living organisms, is one of nature’s most awe-inspiring spectacles and has fascinated humans since time immemorial. Luminous Creatures, written by bioluminescence researcher Michel Anctil, is a chunky book that charts the history of scientific research on this phenomenon by examining the lives and achievements of many of the key players involved. Along the way, it lifts the lid on many of the wondrous details of bioluminescence.
I spy, I spy with my little eye… humans are visually oriented creatures and eyes are fascinating organs. Michael Land, an emeritus (i.e. retired) professor in neurobiology at the University of Sussex, is a world expert on eyes, having studied vision for over 50 years. Next to hundreds of papers, he co-authored the textbook Animal Eyes, which was published in a second edition in 2012, and the short primer The Eye: A Very Short Introduction. Eyes to See is his opportunity to reflect on a long career and simultaneously showcase the astonishing variety of vision, as the book’s subtitle would have it.
Historically, humans have long considered themselves special compared to the natural world around them. It shows, for example, in old depictions where humans are at or near the top of a chain of lifeforms, with only angels and gods above us. Darwin caused a tremendous ruckus by saying we were descended from primates, and evolutionary biology has since had a long history of diminishing our anthropocentric worldview. With The Book of Humans, self-professed science geek Adam Rutherford has written an entertaining exploration of human evolution, showing that, amidst the teeming multitudes of lifeforms surrounding us, we are really not that special. And yet we are.
Orcas or killer whales have been at the centre of a swirling controversy for decades. Popular attractions in aquaria, their plight there has been highlighted in recent books and documentaries, further strengthening opposition to keeping cetaceans (i.e. whales, dolphins, and porpoises) in captivity. However, as Jason M. Colby meticulously documents in this book, there is a cruel irony at play here: this very practice of captivity is what raised our environmental awareness in the first place.
If I asked you to name the most endangered cetacean species, I doubt the vaquita would come to mind. You might mention the baiji, the dolphin living in China’s Yangtze river, but alas, no living members of this species have been seen for years, despite intense search efforts, and the species is presumed extinct. Unfortunately, the vaquita seems to be next in line. Biologist Brooke Bessesen here tells its sad story, revealing the complex world of species conservation.
