Stung!

Lisa-ann Gershwin; Sylvia Earle — Tue, 07 May 2013 05:00:00 GMT

Our oceans are becoming increasingly inhospitable to life—growing toxicity and rising temperatures coupled with overfishing have led many marine species to the brink of collapse. And yet there is one creature that is thriving in this seasick environment: the beautiful, dangerous, and now incredibly numerous jellyfish. As foremost jellyfish expert Lisa-ann Gershwin describes in Stung!, the jellyfish population bloom is highly indicative of the tragic state of the world’s ocean waters, while also revealing the incredible tenacity of these remarkable creatures.

Recent documentaries about swarms of giant jellyfish invading Japanese fishing grounds and summertime headlines about armadas of stinging jellyfish in the Mediterranean and Chesapeake are only the beginning—jellyfish are truly taking over the oceans. Despite their often dazzling appearance, jellyfish are simple creatures with simple needs: namely, fewer predators and competitors, warmer waters to encourage rapid growth, and more places for their larvae to settle and grow. In general, oceans that are less favorable to fish are more favorable to jellyfish, and these are the very conditions that we are creating through mechanized trawling, habitat degradation, coastal construction, pollution, and climate change.

Despite their role as harbingers of marine destruction, jellyfish are truly enthralling creatures in their own right, and in Stung!, Gershwin tells stories of jellyfish both attractive and deadly while illuminating many interesting and unusual facts about their behaviors and environmental adaptations. She takes readers back to the Proterozoic era, when jellyfish were the top predator in the marine ecosystem—at a time when there were no fish, no mammals, and no turtles; and she explores the role jellies have as middlemen of destruction, moving swiftly into vulnerable ecosystems. The story of the jellyfish, as Gershwin makes clear, is also the story of the world’s oceans, and Stung! provides a unique and urgent look at their inseparable histories—and future.

Population Fluctuations in Rodents

Charles J. Krebs — Fri, 19 Apr 2013 05:00:00 GMT

How did rodent outbreaks in Germany help to end World War I? What caused the destructive outbreak of rodents in Oregon and California in the late 1950s, the large population outbreak of lemmings in Scandinavia in 2010, and the great abundance of field mice in Scotland in the spring of 2011? Population fluctuations, or outbreaks, of rodents constitute one of the classic problems of animal ecology, and in Population Fluctuations in Rodents, Charles J. Krebs sifts through the last eighty years of research to draw out exactly what we know about rodent outbreaks and what should be the agenda for future research.

Krebs has synthesized the research in this area, focusing mainly on the voles and lemmings of the Northern Hemisphere—his primary area of expertise—but also referring to the literature on rats and mice. He covers the patterns of changes in reproduction and mortality and the mechanisms that cause these changes—including predation, disease, food shortage, and social behavior—and discusses how landscapes can affect population changes, methodically presenting the hypotheses related to each topic before determining whether or not the data supports them. He ends on an expansive note, by turning his gaze outward and discussing how the research on rodent populations can apply to other terrestrial mammals. Geared toward advanced undergraduate students, graduate students, and practicing ecologists interested in rodent population studies, this book will also appeal to researchers seeking to manage rodent populations and to understand outbreaks in both natural and urban settings—or, conversely, to protect endangered species.

Relentless Evolution

John N. Thompson — Mon, 15 Apr 2013 05:00:00 GMT

At a glance, most species seem adapted to the environment in which they live. Yet species relentlessly evolve, and populations within species evolve in different ways. Evolution, as it turns out, is much more dynamic than biologists realized just a few decades ago.

In Relentless Evolution, John N. Thompson explores why adaptive evolution never ceases and why natural selection acts on species in so many different ways. Thompson presents a view of life in which ongoing evolution is essential and inevitable. Each chapter focuses on one of the major problems in adaptive evolution: How fast is evolution? How strong is natural selection? How do species co-opt the genomes of other species as they adapt? Why does adaptive evolution sometimes lead to more, rather than less, genetic variation within populations? How does the process of adaptation drive the evolution of new species? How does coevolution among species continually reshape the web of life? And, more generally, how are our views of adaptive evolution changing?

Relentless Evolution draws on studies of all the major forms of life—from microbes that evolve in microcosms within a few weeks to plants and animals that sometimes evolve in detectable ways within a few decades. It shows evolution not as a slow and stately process, but rather as a continual and sometimes frenetic process that favors yet more evolutionary change.

Swordfish

Richard Ellis — Mon, 15 Apr 2013 05:00:00 GMT

A perfect fish in the evolutionary sense, the broadbill swordfish derives its name from its distinctive bill—much longer and wider than the bill of any other billfish—which is flattened into the sword we all recognize. And though the majesty and allure of this warrior fish has commanded much attention—from adventurous sportfishers eager to land one to ravenous diners eager to taste one—no one has yet been bold enough to truly take on the swordfish as a biographer. Who better to do so than Richard Ellis, a master of marine natural history? Swordfish: A Biography of the Ocean Gladiator is his masterly ode to this mighty fighter.

The swordfish, whose scientific name means “gladiator,” can take on anyone and anything, including ships, boats, sharks, submarines, divers, and whales, and in this book Ellis regales us with tales of its vitality and strength. Ellis makes it easy to understand why it has inspired so many to take up the challenge of epic sportfishing battles as well as the longline fishing expeditions recounted by writers such as Linda Greenlaw and Sebastian Junger. Ellis shows us how the bill is used for defense—contrary to popular opinion it is not used to spear prey, but to slash and debilitate, like a skillful saber fencer. Swordfish, he explains, hunt at the surface as well as thousands of feet down in the depths, and like tuna and some sharks, have an unusual circulatory system that gives them a significant advantage over their prey, no matter the depth in which they hunt. Their adaptability enables them to swim in waters the world over—tropical, temperate, and sometimes cold—and the largest ever caught on rod and reel was landed in Chile in 1953, weighing in at 1,182 pounds (and this heavyweight fighter, like all the largest swordfish, was a female).

Ellis’s detailed and fascinating, fact-filled biography takes us behind the swordfish’s huge, cornflower-blue eyes and provides a complete history of the fish from prehistoric fossils to its present-day endangerment, as our taste for swordfish has had a drastic effect on their population the world over. Throughout, the book is graced with many of Ellis’s own drawings and paintings, which capture the allure of the fish and bring its splendor and power to life for armchair fishermen and landlocked readers alike.

Bali Marine Rapid Assessment Program 2011

Putu Liza Kusuma Mustika; I Made Jaya Ratha; Saleh Purwanto — Fri, 15 Mar 2013 05:00:00 GMT

This report contains the findings from marine biological assessments of fifty-two sites around the coast of Bali. The purpose of the survey was to collect data on biodiversity and coral reef health in order to provide recommendations for the government of Bali to establish a network of marine protected areas. The team found high diversity and endemism, including at least fifteen species, including many reef fishes and corals that were previously unknown to science. Many coral reefs that had been historically damaged are recovering surprisingly well, yet several threats and management problems remain. Detailed conservation recommendations also are provided.

Ecology of Others

Philippe Descola; Geneviève Godbout; Benjamin P. Luley — Fri, 15 Mar 2013 05:00:00 GMT

Since the end of the nineteenth century, the division between nature and culture has been fundamental to Western thought. In this groundbreaking work, renowned anthropologist Philippe Descola seeks to break down this divide, arguing for a departure from the anthropocentric model and its rigid dualistic conception of nature and culture as distinct phenomena. In its stead, Descola proposes a radical new worldview, in which beings and objects, human and nonhuman, are understood through the complex relationships that they possess with one another.

The Ecology of Others presents a compelling challenge to anthropologists, ecologists, and environmental studies scholars to rethink the way we conceive of humans, objects, and the environment. Thought-provoking and engagingly written, it will be required reading for all those interested in moving beyond the moving beyond the confines of this fascinating debate.
