How Snakes Work: Structure, Function and Behavior of the World's Snakes

By Harvey B. Lillywhite

An individual can examine a snake and spot a creature distinctive unto itself, a reptile with a suite of zoological and organic characteristics which are solely its personal. simply this special animal increases many clinical questions. in regards to evolution, how did such an animal become? How does a snake circulation, and the way do its feel organs range from that of different reptiles? How does it consume, and the way does it reproduce? basically, how does a snake "work"? In How Snakes paintings: The constitution, functionality and behaviour of the World's Snakes, top zoologist Harvey B. Lillywhite has written the definitive medical consultant to the practical biology of snakes. Written for either herpetologists and a extra common viewers with an curiosity within the box, How Snakes paintings positive aspects approximately 200 colour photographs of assorted species of snakes, used to supply visible examples of organic beneficial properties defined within the text.

Chapter themes contain the evolutionary background of the snake, feeding, locomotion, the constitution and serve as of dermis, movement and respiratory, feel organs, sound construction, temperature and thermoregulation, and replica. Containing all of the newest learn and advances in our organic wisdom of the snake, How Snakes paintings is an integral asset to specialist zoologists and fans alike.

Epigenetic Principles of Evolution (Elsevier Insights)

This is often the 1st and simply ebook, to date, to house the causal foundation of evolution from an epigenetic view. through revealing the epigenetic "user" of the "genetic toolkit", this publication demonstrates the primacy of epigenetic mechanisms and epigenetic info in producing evolutionary novelties. the writer convincingly helps his conception with a number of examples from the main diverse fields of biology, by way of emphasizing adjustments in developmental pathways because the uncomplicated resource of evolutionary switch in metazoans.

Conservation Biology: Evolution in Action

The most aim of this publication is to inspire and formalize the infusion of evolutionary considering into mainstream conservation biology. It reports the evolutionary foundations of conservation concerns, and unifies conceptual and empirical advances in evolutionary conservation biology. The publication can be utilized both as a main textbook or as a supplementary studying in a complicated undergraduate or graduate point path - more likely to be known as Conservation Biology or occasionally Evolutionary Ecology.

Introduction to Genomics

Our genome is the blueprint to our lifestyles: it encodes all of the details we have to improve from a unmarried phone right into a highly advanced practical organism. yet how can we determine the genes that make up our genome? How can we ensure their functionality? and the way do assorted genes shape the regulatory networks that direct the procedures of existence?
