Download or read book Handbook of Salamanders written by Sherman Chauncey Bishop and published by Cornell University Press. This book was released on 1994 with total page 580 pages. Available in PDF, EPUB and Kindle. Book excerpt: Despite their abundance in many parts of North America, salamanders have generally been neglected by all but a few specialists. In this book--first published in 1943--Sherman C. Bishop discusses in a lively but authoritative manner the 126 species and subspecies of salamanders that are known to exist in the United States, Canada, and Baja California.Group by group, Bishop describes salamanders in accounts that give the common and technical names, type of locality, range, habitat, size, anatomical characteristics, color, breeding habits, and relationships--all in a uniform arrangement that makes the handbook especially convenient for studying both living animals and laboratory specimens. His brief introduction surveys the relationships and general habits of salamanders and gives information on collecting and preserving them. In his foreword to the 1994 reprint edition, Edmund D. Brodie, Jr., a specialist on salamanders, updates the taxonomy of the group.
Download or read book Ecology and Evolution of Poeciliid Fishes written by Jonathan P. Evans and published by University of Chicago Press. This book was released on 2011-09-26 with total page 424 pages. Available in PDF, EPUB and Kindle. Book excerpt: The history of biology is populated by numerous model species or organisms. But few vertebrate groups have aided evolutionary and ecological research more than the live-bearing fishes of the family Poeciliidae. Found throughout tropical and subtropical waters, poeciliids exhibit a fascinating variety of reproductive specializations, including viviparity, matrotrophy, unisexual reproduction, and alternative mating strategies, making them ideal models for research on patterns and processes in ecology, behavior, and evolution. Ecology and Evolution of Poeciliid Fishes is a much-needed overview of the scientific potential and understanding of these live-bearing fishes. Chapters by leading researchers take up a wide range of topics, including the evolution of unisexual reproduction, life in extreme environments, life-history evolution, and genetics. Designed to provide a single and highly approachable reference, Ecology and Evolution of Poeciliid Fishes will appeal to students and specialists interested in all aspects of evolutionary ecology.

Download or read book Sex Color and Mate Choice in Guppies written by Anne Houde and published by Princeton University Press. This book was released on 2019-12-31 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Trinidadian guppy (Poecilia reticulata) is well known to biologists and home aquarium enthusiasts alike. Scientists have studied guppies for most of the twentieth century. Some of the most intensive recent research has been conducted by behavioral ecologists, who have found that the guppy mating system makes guppies especially useful in the study of sexual selection and mate choice. By observing guppy behavior in aquaria, researchers hope to obtain new insights into how selection operates in natural populations. Here Anne Houde summarizes and synthesizes the scientific work done to date, relates the empirical findings on guppies to current themes in sexual selection theory, and suggests new directions for future research. This book describes the sexual behavior of guppies and examines how mate choice by females leads to the evolution of the conspicuous colors and the courtship displays for which guppies are widely recognized. The author shows that female guppies prefer males with bright color patterns, especially those with orange spots, and that the mating preferences of females lead to sexual selection on both color patterns and courtship displays of males. Houde's work addresses a number of areas that are of interest in sexual selection, including the remarkable degree of plasticity and evolutionary lability of sexual behavior in guppies, geographic variation in mating preferences, possible mechanisms for the evolution of female mating preferences, and the role of sexual selection in speciation. In conclusion, the author explores the implications of her findings for behavioral ecologists who study sexual selection in other species.
Download or read book Field Guide to the Ladybirds of Great Britain and Ireland written by Helen Roy and published by Bloomsbury Publishing. This book was released on 2018-11-29 with total page 162 pages. Available in PDF, EPUB and Kindle. Book excerpt: 'A ground-breaking identification guide ... the perfect marriage of artistic excellence, deep knowledge and, dare I say it, of scientists' genuine affection.' - Brett Westwood This brand new illustrated field guide covers all 47 species of ladybird occurring in the British Isles in a handy and easy-to-use format. Twenty-seven species are colourful and conspicuous and easily recognised as ladybirds; the remaining species are more challenging, but the clear illustrations and up-to-date text in this guide will help to break down the identification barriers. A useful introduction provides an overview of ladybird ecology, tips on studying and recording, and suggested sites for finding ladybirds. The main part of the book comprises detailed species texts, covering field characters, food, habitats, suggested survey methods, ranges, conservation statuses and distribution trends. An illustrated at-a-glance identification guide and helpful pointers for differentiating similar-looking species are also included. With 102 colour photographs and 47 distribution maps, combined with Richard Lewington's peerless artwork, this is the definitive guide to one of our most cherished and charismatic insect groups.
