Download or read book The Evolution of Insect Mating Systems written by David M. Shuker and published by . This book was released on 2014 with total page 355 pages. Available in PDF, EPUB and Kindle. Book excerpt: Insects display a staggering diversity of mating and social behaviours. Studying these systems provides insights into a wide range of evolutionary and behavioural questions, such as the evolution of sex, sexual selection, sexual conflict, and parental care. This edited volume provides an authoritative update of the landmark book in the field, The Evolution of Insect Mating Systems (Thornhill and Alcock, 1983), which had such a huge impact in shaping adaptationist approaches to the study of animal behaviour and influencing the study of the evolution of reproductive behaviour far beyond the taxonomic remit of insects. This accessible new volume brings the empirical and conceptual scope of the original book fully up to date, incorporating the wealth of new knowledge and research of the last 30 years. It explores the evolution of complex forms of sex determination in insects, and the role of sexual selection in shaping the evolution of mating systems. Selection arising via male contest competition and female choice (both before and after copulation) are discussed, as are the roles of parasites and pathogens in mediating the strength of sexual selection, and the role that parental care plays in successful reproduction. The Evolution of Insect Mating Systems is suitable for both graduate students and researchers interested in insect mating systems or behaviour from an evolutionary, genetical, physiological, or ecological perspective. Due to its interdisciplinary and concept-driven approach, it will also be of relevance and use to a broad audience of evolutionary biologists.

Download or read book The North American Perching and Dabbling Ducks written by Paul Johnsgard and published by Lulu.com. This book was released on 2017-03 with total page 229 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume, the fourth in a series of books that collectively update and expand P.A. Johnsgard's 1975 The Waterfowl of North America, summarizes research findings on this economically and ecologically important group of waterfowl. The volume includes the mostly tropical perching duck tribe Cairinini, of which two species, the muscovy duck and the wood duck, are representatives. Both species are adapted for foraging on the water surface, mostly on plant materials, but typically perch in trees and nest in elevated tree cavities or other elevated recesses. This volume also includes the dabbling, or surface-feeding, duck tribe Anatini, a large assemblage of duck species that mainly forage on the water surface but nest on the ground, or only very rarely in elevated locations. Of this tribe, 12 species that regularly breed in North America are included, among them such familiar species as mallards, wigeons, pintails, and teal. Descriptive accounts of the distributions, populations, ecologies, social-sexual behaviors, and breeding biology of all these species are provided, together with distribution maps. Five additional Eurasian and West Indian species have been reported several times in North America; these have been included with more abbreviated accounts, but all 17 species are illustrated by drawings, photographs, or both. The text includes about 84,000 words and contains more than 1,000 references. There are also 12 distribution maps, 21 drawings, 28 photographic plates, and 58 anatomical or behavioral sketches.

This book was released on 1996-05-30 with total page 438 pages. Available in PDF, EPUB and Kindle. Book excerpt: Some birds mate for life, while others have many partners. Why? In this book, fourteen classic studies of bird behaviour are brought together to compare the different partnership patterns from ecological and evolutionary perspectives. Often there is a battle of the sexes, as individual birds behave in the way that serves their best interests. Introductory and concluding chapters review the latest thinking on this fascinating subject. - ;Some birds mate for life, while others have many partners. In this book, fourteen studies are brought together to compare different partnership patterns from ecological and evolutionary perspectives. The subjects have been chosen to include the same species living in different habitats (Sparrowhawks) and at different population densities (Great Tits). There are comparisons between closely related species (Mute Swans and Bewick's Swans). The studies span the globe and the behavioural gradient, from Iceland's strictly monogamous Whooper Swans to Australia's sexually promiscuous Splendid Fairy-wrens. In all cases, sexual and social relationships strongly influence a bird's survival and breeding success. -
