The amphibians and reptiles of New York state: identification, natural history and conservation

Introduction (in part) New York State hosts a magnificent suite of some 69 native species of amphibians and reptiles. These include such wonders as stinkpots, hellbenders, queen snakes, softshells, tiger salamanders, red efts, mink frogs, and spadefoots. This said, a general guide to the state’s salamanders, frogs, turtles, lizards, and snakes has long been lacking. The primary reason has been a scarcity of detailed information about the distributions...

Tadpoles: the biology of anuran larvae

In our own juvenile stage, many of us received our wide-eyed introduction to the wonders of nature by watching the metamorphosis of swimming tadpoles into leaping frogs and toads. The recent alarming declines in amphibian populations worldwide and the suitability of amphibians for use in answering research questions in disciplines as diverse as molecular systematics, animal behavior, and evolutionary biology have focused enormous attention on tadpoles....

Amphibian declines: the conservation status of United States species

Preface (in part)  For much of the past decade and a half, reports of amphibian declines and developmental malformations have been featured in the scientific and popular press. These reports typically open or close with the question: Are amphibians telling us something about the state of the environment—are they canaries in the coal mine? The answer to this question, we now know, is an unequivocal yes. The first hint that all was not well...

The biology of sea turtles Volume II

Preface The success of the first volume of The Biology of Sea Turtles revealed a need for broad but comprehensive reviews of recent major advances in sea turtle biology. At that time, book size constraints as well as the fast-paced changes in some fields dictated that this need could be only partially addressed in a single volume. Many important topics were not covered and were left for future volumes. Volume II emphasizes practical aspects of...

Biology of turtles

Preface The first beasts that we identify as turtles emerged abruptly in the Triassic about 220 million years ago. Since then, countless diverse lineages of turtles—terrestrial, marine, freshwater, and in-between— have come and gone, yet many lineages persist for tens of millions to more than 100 million years. All bring with them the suite of traits that are uniquely turtle: a bony shell, usually a retractable neck, lack of trunk musculature,...
