Gopher Tortoises: Nature’s Ecosystem Engineers!


Book Description

Most people have never seen an endemic North American gopher tortoise. They have limited habits but can be found west and east of the Mississippi River. There are small regions in the American southwest, but the largest population is found in the "Deep South," particularly southeast Texas, southeast Lousiana, southern Mississippi, Alabama, Georgia, southeastern South Carolina, and most of Florida. These land tortoises are threatened and federally protected. Their importance in the ecosystem is vital. They have been identified as keystone species as many plants and more than 350 other animals, rely upon the gopher tortoises for survival. Ensuring that gopher tortoises do not lose their habitats ensures that the ecosystem is healthy and vibrant. At the current rate of change, gopher tortoises will lose 20 percent of their habitat in the next 40 years.




The Gopher Tortoise


Book Description

Full-color book for children ages 10 and up. Details the life of the gopher tortoise and how it is tied in with other animals. Also discusses how the encroachment into the gopher tortoise's habitat is affecting the environment and the tortoise.




Keystone Species: Nature’s Maintenance Managers


Book Description

For many years biologists and ecologists focused on the bottom-up approach to how an ecosystem managed itself. However, in the late 1960s, Dr. Robert Paine began seeing a different ecological trend. His data began revealing that some organisms, often apex predators, actually managed (secured) the characteristics of their habitat by either predation or some behavior that maintained the health and vitality of the ecosystem. Paine called these “keystone species,” based on the idea that were these organisms removed, then the environment would decline in health and eventually fail, falling prey to becoming a monoculture. His studies with starfish and mussels are a classic, and he was able to replicate the hypothesis in other habitats. This book revisits 14 of the organisms addressed in the first 39 issues of the Love of Nature series.




Reptile Ecology and Conservation


Book Description

This practical handbook of reptile field ecology and conservation brings together a distinguished, international group of reptile researchers to provide a state-of-the-art review of the many new and exciting techniques used to study reptiles. The authors describe ecological sampling techniques and how they are implemented to monitor the conservation status and population trends of snakes, lizards, tuatara, turtles, and crocodilians throughout the world. Emphasis is placed on the extent of statistical inference and the biases associated with different techniques and analyses. The chapters focus on the application of field research and data analysis for achieving an understanding of reptile life history, population dynamics, movement patterns, thermal ecology, conservation status, and the relationship between reptiles and their environment. The book emphasises the need for thorough planning, and demonstrates how a multi-dimensional approach incorporates information related to morphology, genetics, molecular biology, epidemiology, statistical modelling, animal welfare, and biosecurity. Although accentuating field sampling, sections on experimental applications in laboratories and zoos, thermal ecology, genetics, landscape ecology, disease and biosecurity, and management options are included. Much of this information is scattered in the scientific literature or not readily available, and the intention is to provide an affordable, comprehensive synthesis for use by graduate students, researchers, and practising conservationists worldwide.




Tainted


Book Description

Three-fourths of scientific research in the United States is funded by special interests. Many of these groups have specific practical goals, such as developing pharmaceuticals or establishing that a pollutant causes only minimal harm. For groups with financial conflicts of interest, their scientific findings often can be deeply flawed. To uncover and assess these scientific flaws, award-winning biologist and philosopher of science Kristin Shrader-Frechette uses the analytical tools of classic philosophy of science. She identifies and evaluates the concepts, data, inferences, methods, models, and conclusions of science tainted by the influence of special interests. As a result, she challenges accepted scientific findings regarding risks such as chemical toxins and carcinogens, ionizing radiation, pesticides, hazardous-waste disposal, development of environmentally sensitive lands, threats to endangered species, and less-protective standards for workplace-pollution exposure. In so doing, she dissects the science on which many contemporary scientific controversies turn. Demonstrating and advocating "liberation science," she shows how practical, logical, methodological, and ethical evaluations of science can both improve its quality and credibility -- and protect people from harm caused by flawed science, such as underestimates of cancers caused by bovine growth hormones, cell phones, fracking, or high-voltage wires. This book is both an in-depth look at the unreliable scientific findings at the root of contemporary debates in biochemistry, ecology, economics, hydrogeology, physics, and zoology -- and a call to action for scientists, philosophers of science, and all citizens.




The Evolution Underground


Book Description

Humans have "gone underground" for survival for thousands of years, from underground cities in Turkey to Cold War-era bunkers. But our burrowing roots go back to the very beginnings of animal life on Earth. Many animal lineages alive now—including our own—only survived a cataclysmic meteorite strike 65 million years ago because they went underground.On a grander scale, the chemistry of the planet itself had already been transformed many millions of years earlier by the first animal burrows which altered whole ecosystems. Every day we walk on an earth filled with an underground wilderness teeming with life. Most of this life stays hidden, yet these animals and their subterranean homes are ubiquitous, ranging from the deep sea to mountains, from the equator to the poles. Burrows are a refuge from predators, a safe home for raising young, or a tool to ambush prey. Burrows also protect animals against all types of natural disasters. Filled with spectacularly diverse fauna, acclaimed paleontologist and ichnologist Anthony Martin reveals this fascinating, hidden world that will continue to influence and transform life on this planet.




Biology of Rove Beetles (Staphylinidae)


Book Description

Rove beetles (Staphylinidae) are common elements of the soil biota, living in the litter and deeper soil layers. Although they are one of the most diverse and speciose groups of insects, no comprehensive books on their general evolution and ecology are as yet available. This book fills that gap, discussing significant aspects and active research examples in the fields of phylogeny and systematics, ecology and conservation, and reproduction and development. The combination of review chapters and case studies provides an excellent introduction to the biology of rove beetles and enables readers to become familiar with active research fields in this megadiverse group of beetles. Offering easy access to these fields, it also demonstrates how staphylinids are used as bioindicators in applied ecosystem research, including that concerning conservation issues. Experienced scientists and beginners alike find the diversity of subjects covered intriguing and inspiring for continuing and starting their own research. The book is intended for students and researchers in biology and zoology (entomology), including morphologists, ecologists, soil scientists, evolutionary biologists, paleontologists, biogeographers, taxonomists and systematists.







Half-Earth: Our Planet's Fight for Life


Book Description

"An audacious and concrete proposal…Half-Earth completes the 86-year-old Wilson’s valedictory trilogy on the human animal and our place on the planet." —Jedediah Purdy, New Republic In his most urgent book to date, Pulitzer Prize–winning author and world-renowned biologist Edward O. Wilson states that in order to stave off the mass extinction of species, including our own, we must move swiftly to preserve the biodiversity of our planet. In this "visionary blueprint for saving the planet" (Stephen Greenblatt), Half-Earth argues that the situation facing us is too large to be solved piecemeal and proposes a solution commensurate with the magnitude of the problem: dedicate fully half the surface of the Earth to nature. Identifying actual regions of the planet that can still be reclaimed—such as the California redwood forest, the Amazon River basin, and grasslands of the Serengeti, among others—Wilson puts aside the prevailing pessimism of our times and "speaks with a humane eloquence which calls to us all" (Oliver Sacks).
