With breathtaking complexity and haunting beauty, the songs of whales have long fascinated scientists. Whales are the only mammals that can sing continuously for ten hours or more, changing the unique songs they sing every year. In Why Whales Sing (JHU Press, 2025), bioacoustician and cognitive scientist Eduardo Mercado transforms our understanding of these enigmatic sounds and proposes a groundbreaking theory that challenges decades of established science.

Fifty years of field research have led most scientists to conclude that humpback whales sing for the same reason that birds do: to advertise their sexual fitness. But if whale songs are nothing more than tools of attraction, why do whales sing even when they're alone and there are no listeners nearby? In light of modern advances in neuroscience and ocean acoustics, Mercado reaches the surprising conclusion that whales may not actually be "singing," but rather engaging in an activity more commonly associated with dolphins and bats--echolocating--which enables them to see their world with sound. By incessantly streaming sounds while listening closely to the returning echoes, whales may be actively tuning their brains in ways that allow them to monitor the movements of silent whales located miles away.

Sophisticated, long-range sonar can enable whales to perceive their vast underwater worlds in unimaginable ways. From the military origins of whale song recordings to the persistent mysteries of cetacean communication, this book displays the wonder of whales and reshapes how we view their intelligence, behavior, and acoustic mastery.

In her new book, Caring for Glaciers: Land, Animals, and Humanity in the Himalayas (University of Washington Press, 2019), Karine Gagné explores how relations of reciprocity between land, humans, animals, and glaciers foster an ethics of care in the Himalayan communities of Ladakh. She explores the way these relations are changing due to climate change, the growth of the wage economy at the expense of traditional agricultural and pastoral lifestyles, and increased military presence resulting from Ladakh's status as a border area. This book will be of interest to those who are interested in the anthropology of ethics, ethics in Buddhist communities, and the anthropology of climate change.

The pig played a fundamental role in the German Democratic Republic's attempts to create and sustain a modern, industrial food system built on communist principles. By the mid-1980s, East Germany produced more pork per capita than West Germany and the UK, while also suffering myriad unintended consequences of this centrally planned practice: manure pollution, animal disease, and rolling food shortages.

In Communist Pigs: An Animal History of East Germany's Rise and Fall (University of Washington Press, 2020), historian Thomas Fleischman uncovers three types of pig that played roles in this history: the industrial pig, remade to suit the conditions of factory farming; the wild boar, whose overpopulation was a side effect of agricultural development rather than a conservation success story; and the garden pig, reflective of the regime's growing acceptance of private, small-scale farming within the planned economy.

Fleischman chronicles East Germany's journey from family farms to factory farms, explaining how communist principles shaped the adoption of industrial agriculture practices. More broadly, Fleischman argues that agriculture under communism came to reflect standard practices of capitalist agriculture, and that the pork industry provides a clear illustration of this convergence. His analysis sheds light on the causes of the country's environmental and political collapse in 1989 and offers a warning about the high cost of cheap food in the present and future.

Thomas Fleischman is an assistant professor of history at the University of Rochester.

Anastasija Ropa joins Jana Byars to talk about The Medieval Horse (Reaktion, 2025), a book that explores the role of horses across the medieval world, from the Kievan Rus' and Scandinavia to Central Europe, Byzantium, the Arab world and Asia, including China and India. Covering the early medieval period to the late Middle Ages, it examines how horses shaped societies, warfare and culture and how their legacy persists in traditional equestrian sports today. Drawing on little-known primary sources, artefacts, and the author’s hands-on experience with historical horsemanship, the book offers a vivid account of the deep connection between people and horses. Combining scholarly insight with practical knowledge, this is the most comprehensive study of medieval horses in Europe and Asia to date.

Rigby’s Encyclopaedia of the Herring: Adventures with the King of Fishes (Hurst, 2025) by Graeme Rigby contains almost everything you didn’t know you needed to know about Atlantic herrings. (Pacific and Baltic varieties are in there too.) Herrings make the world bigger: with spawnings seen from space, a trillion individuals make this one of the tastiest and most abundant vertebrates on Earth.

From ‘A Beginning’ to ‘Zuiderzee’, count the wars fought over herrings; don’t forget Scotland vs the Holy Roman Empire. The herring’s high-pitched farts were logged as Soviet submarines, and one herring joke featured in a Jonson play, four Shakespeare plays and the glorious, suppressed fantasia Nashes Lenten Stuffe. Herrings mock taxonomists; physically change with sea temperature and salinity; stuff predators full to bursting, then swim away.

The Great Sardine Litigation? The true history of kippers? Bloaters? Reds? Chopped herring? Shuba? All this and more. Between sustainable fishery genetics, sixteenth-century Bavaria’s ‘Herrings, herrings, stinking herrings’, and Van Gogh’s ear, every entry is a story, a comic journey, an adventure. Some even come with recipes.

Dr. Rebecca van Laer and her partner purchase a home and move in with their senior cats, Toby and Gus. Their loved ones see this as a step toward an inevitable future-first comes the house, then a dog, then a child. But what if they are just cat people?
Moving between memoir, philosophy, and pop culture, Cat (Bloomsbury, 2025) is a playful and tender meditation on cats and their people, part of the Object Lessons series. Van Laer considers cats' role in her personal narrative, where they are mascots of laziness and lawlessness, and in cultural narratives, where they appear as feminine, anarchic, and maladapted, especially in comparison to dogs.
From the stereotype of the 'crazy cat lady' to the joy of cat memes to the grief of pet loss, van Laer demonstrates that the cat-person relationship is free of the discipline and dependence required by parenting (and dog-parenting), creating a less hierarchical intimacy that offers a different model for love.

As permafrost in Siberia continues to melt and the steppe in the Gobi turns to desert, people in Mongolia are faced with overlapping climate crises. Some nomadic herders describe climate change as the end of a world. They are quick to add that the world has ended before for Indigenous people in North Asia, as waves of colonialism have left the steppe with a complicated web of apocalypses. A Song for the Horses by K. G. Hutchins examines cases in which people respond to the pressures of climate change by drawing on cultural heritage to foster social resiliency. In this episode, K. G. joins me to discuss his research on the morin khuur, or “horse fiddle,” in Mongolia, and how Mongolians use the traditional instrument to express and envision human and more-than-human futures against the backdrop of anthropogenic climate change.

The humble goat has played a surprising and important role throughout the history of the United States. Despite this, goats are often overlooked by many Americans, even if they have strong opinions about these complex creatures. In Goats in America: A Cultural History (Oregon State UP, 2025) Dr. Tami Parr calls attention to these disregarded animals, uncovering the remarkable stories behind everything from goat meat and milk to goat yoga and more.

Since arriving in North America with cattle and other domesticated livestock in the sixteenth century, goats have provided people sustenance and valuable products, including milk, meat, and mohair. But humans did not appreciate the animals, and as a result, throughout much of American history goats were persecuted as public nuisances and symbols of degenerate behavior. Nevertheless, over the centuries the tenacious goat has overcome many of these stereotypes and secured a spot in the hearts and minds of modern Americans, who love goat cheese and embrace goats as social media stars.

Examining key moments and notable developments in goat history and culture, Goats in America outlines the history and evolving role of goats in communities across the country, from San Francisco and New York City to rural Wisconsin and the Navajo Nation. Parr shows that the evolving reputation of goats in American society ultimately reveals more about humans than it does about goats themselves. So, the next time you are enjoying your favorite goat cheese, take a moment to consider the history and role of goats within American culture.

Animals speak. Plants do too. Seas and mountains are not a mute background to human actions, but have interests and agency. Many more-than-human beings are political actors. All of us are part of a web of relations in which we affect others and are affected by them. To counter the current ecological destruction and find more just ways to co-exist, humans need new ways of doing politics with other earth beings. In Multispecies Assemblies (Vine Press, 2025), Dutch philosopher Eva Meijer develops such a new political model: the multispecies assembly. Multispecies assemblies are a form of direct democracy in which some beings speak for themselves and others are represented. Living differently as humans is possible, but we must begin to listen to others, and learn from them.

Eva Meijer is a philosopher, visual artist, writer and singer-songwriter. They write novels, philosophical essays, academic texts, poems and columns, and their work has been translated into over twenty languages. Recurring themes are language including silence, madness, nonhuman animals, and politics. Meijer also works as a postdoctoral researcher at the University of Amsterdam, writes essays and columns for Dutch newspapers, and is a member of the Multispecies Collective.

Kyle Johannsen is Sessional Faculty Member in the Department of Philosophy at Trent University. His most recent authored book is Wild Animal Ethics: The Moral and Political Problem of Wild Animal Suffering (Routledge, 2021).

Animals are staging a revolution—they’re just not telling us. From radioactive boar invading towns to jellyfish disarming battleships, Animal Revolution (U Minnesota Press, 2022) threads together news accounts and more in a powerful and timely work of creative, speculative nonfiction that imagines a revolution stirring and asks how humans can be a part of it. If the coronavirus pandemic has taught us anything, it is that we should pay attention to how we bump up against animal worlds and how animals will push back. Animal Revolution is a passionate, provocative, cogent call for us to do so.

Ron Broglio reveals how fur and claw and feather and fin are jamming the gears of our social machine. We can try to frame such disruptions as environmental intervention or through the lens of philosophy or biopolitics, but regardless the animals persist beyond our comprehension in reminding us that we too are part of an animal world. Animals see our technologies and machines as invasive beings and, in a nonlinguistic but nonetheless intensive mode of communicating with us, resist our attempts to control them and diminish their habitats. In doing so, they expose the environmental injustices and vulnerabilities in our systems.

A witty, informative, and captivating work—at the juncture of posthumanism, animal studies, phenomenology, and environmental studies—Broglio reminds us of our inadequacy as humans, not our exceptionalism.

Ron Broglio is professor of English, director of Desert Humanities, and associate director of the Institute for Humanities Research at Arizona State University. He is author or editor of several books, including Beasts of Burden: Biopolitics, Labor, and Animal Life and Surface Encounters: Thinking with Animals and Art.
