Where do turtles hail from? Why and how did they acquire shells? These questions have spurred heated debate and intense research for more than two hundred years. Brilliantly weaving evidence from the latest paleontological discoveries with an accessible, incisive look at different theories of biological evolution and their proponents, Turtles as Hopeful Monsters tells the fascinating evolutionary story of the shelled reptiles. Paleontologist Olivier Rieppel traces the evolution of turtles from over 220 million years ago, examining closely the relationship of turtles to other reptiles and...

When a loved one dies in a mysterious manner, we rely on coroners and medical examiners to tell us what happened. The stakes are high: Coroners seek justice for the dead, exoneration for the wrongfully accused, and closure for the families of victims. They are always on call and work closely with law enforcement.

Author Robert S. West, who served as a physician-coroner in rural Kootenai County, Idaho, from 1970 to 2011, delves into the challenges he faced on the job. While he often lacked resources, he always did the best he could to serve his community, solving numerous mysteries...

Amphibians and Reptiles of Nebraska is an authoritative review and reference to the 61 species of reptiles and amphibians known to occur within the boundaries of the state of Nebraska. It is the first comprehensive summary of the herpetofauna since George Hudson s 1942 book on the same topic which covered the 56 species then known to occur in Nebraska. It is well illustrated with 248 color photographs and 125 maps and 18 line drawings. The text provides both an introduction for the amateur and a review for the professional. A detailed account is given for each species. A general...

Generously illustrated, this essential handbook for herpetologists, ecologists, and naturalists features comprehensive keys to eggs, embryos, salamander larvae, and tadpoles; species accounts; a glossary of terms; and an extensive bibliography. The taxonomic accounts include a summarization of the morphology and basic natural history, as well as an introduction to published information for each species. Tadpole mouthparts exhibit major characteristics used in identifications, and the book includes illustrations for a number of species. Color photographs of larvae of many species are also...

The species of hake, making up the genus Merluccius, are commercially important and currently largely over exploited, with many stocks badly depleted and showing only limited signs of recovery.

From the end of the 1990s, concepts such as sustainability, ecosystem-based approaches to fisheries management, a code for the responsible conduct for fisheries, governance and others have emerged or have been considered by politicians, stakeholders and society. Moreover, new tools for stock assessment have been developed. But many hake stocks of the genus Merluccius show no sign of...

Map turtles and sawbacks, found in and along rivers from Texas to Florida and north to the Great Lakes, fascinate ecologists and evolutionary biologists. Over a short geologic time span, these turtles achieved exceptional biological diversification. Their diets are also exceptionally diverse, and a significant difference in size distinguishes males from females....
