BOOK REVIEW: Nature is Never Silent by Madlen Ziege
My rating: 4 of 5 stars
Out: Hardcover out February 8, 2021 [e-book is out now]
The central premise of this book is that humans miss the tremendous amount of communication that is going on among and between other species. We miss it because we think of communication in an extremely limited way that revolves around visual and auditory expressions of human style languages. It doesn’t occur to us that different senses (e.g. smell) or other activities (e.g. stinging or passing gases,) could be used to convey messages as overt as, “Don’t touch me!” to as complex as, “There are good flowers to the southeast, roughly four-hundred meters along this line” or “Watch out! Some beetles have started chewing on my bark.”
While one might still dismiss all this communication as extremely simple compared to the infinitely complicated endeavor humans have made communicating, it’s not all just warning signaling. Many species engage in a form of communication that most people would probably attribute to humanity alone, specifically, deception. There are female fireflies who cannot only send a mating signal to males of her species to engage in reproduction, but can send counterfeit signals of other species to attract a male of another species of which she can make a snack.
It’s also important to note that it’s not just the species most similar to us who communicate. There are chapters devoted to both unicellular creatures and plants, species that one might be surprised to learn are quite active communicators.
I found this to be a highly thought-provoking book for the nature-lover, and I’d recommend it for anyone who wants to expand his or her horizons with respect to what is being transmitted in the natural world on those cold and quiet days when it seems like not a creature is stirring, and yet there’s always something.

BOOK REVIEW: Empire of Ants by Susanne & Olaf Foitzik
Empire of Ants: The Hidden World and Extraordinary Lives of Earth’s Tiny Conquerors by Susanne Foitzik
My rating: 5 of 5 stars
Out: May 6, 2021
In love with our own grandeur, most humans don’t give a thought to the magnificence of other species, and this is particularly true of ants. People use ants as their go-to being to fill in the SAT Analogy “Gods are to Humans as Humans are to ______________.” When we want to explain how some more capable entity (be it a god, a trans-galactic alien species, or an advanced artificial intelligence) is more likely to kill us through indifference than through maliciousness, we draw upon the image of an ant about to be crushed under the boot of a person who’s just going about his day, harboring no ill-will towards his six-legged neighbors.
This book will roll back that smug attitude, impressing the reader not only with all the little-known but intriguing behaviors of ants, but also with the range of skills employed by ants that we humans have always thought of as our unique bailiwick – e.g. city building, agriculture, slavery, war, and communication of complex ideas.
The book consists of fourteen chapters and a brief epilogue. The introductory chapter not only prepares the reader to be more impressed by ants, it also explains how crucial ants are collectively to our ecosystems. Chapter two explores the ant caste system in much more detail than the usual queen / worker / drone distinction, and it also explains how sex is determined in a manner quite different than that to which we are used. Chapter three continues an extensive discussion of reproduction that was begun in the previous chapter.
Chapter four dives into what might be called the governance of ant colonies. That may sound grandiose (and, in some sense, it is) but we are talking about huge populations living in a relatively small space. While sci-fi might have one imagining the queen ruling with an iron first while all others act as mindless automatons, the truth is very different, and – in fact – after establishment of the nest, the queen leaves the the thinking business altogether. Chapters five and six investigate the subjects of communication and navigation, respectively. Ants have a tremendously varied set of chemical emitters and receptors, allowing them to communicate a wide range of messages with great clarity. They also communicate through physical contact. Anyone who has ever seen a line of ants in convoy probably suspects that ants must be skilled at getting where they need to go and back. This chapter explains the methods by which ants achieve this purposeful motion, from chemical signals to navigation by the sun to – in some cases – an internal magnetic compass.
Chapter seven takes the reader into the realm of ant militaries, elucidating how they hunt, bivouac, and carry out the various tasks required of them. Chapter eight introduces the question of how colonies (that can be on par with human cities with respect to population) feed everyone, and gives special attention to leafcutter supply chain logistics and in-colony fungiculture. Chapter nine examines the lives of tree-dwelling ants. In this chapter, we learn that not only do ants engage in activities we think of as human; some also perform activities we associate with other species – such as silk weaving. Chapter ten continues the book’s examination of ant agriculture by explaining how some ants keep aphids as livestock [the aphids consume leaves and excrete sugars as a waste product because there is far more of it than they need for their own purposes.]
While chapter seven indicated how ants share some of the less palatable habits of humans – specifically, war, chapter eleven delves into some of the downright loathsome activities these insects share with our species – including: enslavement and theft. Chapter twelve identifies some of the threats to ant health and well-being, including tape worms and fungal parasites. You may have read about the fungus that can hijack an ant’s nervous system to turn it into a zombie (Ophiocordyceps camponoti-floridani,) eventually the fruiting body of the cordyceps pops out of the ant’s head to release spores (after the fungus has “driven” the ant high up into a tree from which the spores can be widely distributed.)
Chapter 13, entitled “The Path to World Domination,” is largely about how invasive species have come to take over in many parts of the world. This includes fire ants, which the Spanish (unwittingly) hauled from Mexico to the Philippines, from which the insects were dispersed all over the world via trade routes. While — throughout the entire book — intriguing ant behaviors are mentioned, the final chapter collects together a group of particularly unlikely skills that are witnessed among ants. My favorites were ants that could glide back to tree trunks when knocked off a limb, as well as another species that could catapult themselves through the air.
The book is well-illustrated, employing both drawings and color photographs. The photographs are particularly useful for showing some of the stranger species and – in a few cases – behaviors that can be difficult to visualize. There is an extensive “further reading” section that is organized by chapter.
“Empire of Ants” provides a fascinating look at an underappreciated species. Just as Peter Wohlleben’s “The Hidden Life of Trees” changed the way I looked at trees, this book changed the way I see ants. I’d highly recommend the book for anyone interested in the natural world.
