Promiscuity: An Evolutionary History of Sperm Competition "It is a curious paradox that reproductive biologists, so obsessed with the mechanics of reproduction, have rarely considered why so much variation exists in the copulation frequency of different species. Progress 07/26/02 to 07/23/07 Outputs Progress Report Objectives (from AD) Determine how and when poultry sperm lose functional competence during liquid and cryogenic storage and use as a basis for developing successful sperm storage methods in vitro. Determine the influence of sperm phenotype (mobility, fertilizing capability) on liquid and cryogenic storage of turkey sperm, as .
Whether you want the wide sweep of history or details such as sperm nests, and half siders, or more pedestrian topics such as how female Acorn Woodpeckers gain acceptance to new groups, The Wisdom of Birds is a book you'll be glad to own, and you will return to it often." – George Clulow, BC Birds. An important empirical test of the theoretical predictions of sexual selection theory, this book presents a long-term field study of the monagamous barn swallow. By using information on behaviour, ecology, morphology, genetics, and evolution, the book reviews this theory and its two components: male-male competition and female choice.
Competition is one of the most important factors controlling the distribution and abundance of living creatures. Sperm cells racing up reproductive tracts, beetle larvae battling inside single seeds, birds defending territories, and trees interfering with the light available to neighbours, are all engaged in competition for limited resources. This textbook helped to define the field of Behavioural Ecology. In this fourth edition the text has been completely revised, with new chapters and many new illustrations and full colour photographs. The theme, once again, is the influence of natural selection on behaviour an animals struggle to survive and reproduce by exploiting and competing for resources, avoiding predators, selecting.

Sperm Competition in Birds addressess the following topics: Both functional and causal aspects of the subject The importance of sperm competition in different avian mating systems The relationship between sperm competition and male and female reproductive anatomy and Format: Paperback. Sperm Competition and Sexual Selection presents the intricate ways in which sperm compete to fertilize eggs and how this has prompted reinterpretations of breeding behavior.
This book provides a theoretical framework for the study of sperm competition, which is a central part of sexual selection.
Sperm competition is the competitive process between spermatozoa of two or more different males to fertilize the same egg during sexual ition can occur when females have multiple potential mating partners.
Greater choice and variety of mates increases a female's chance to produce more viable offspring. However, multiple mates for a female means each individual male has. Sperm Competition and the Evolution of Animal Mating Systems describes the role of sperm competition in selection on a range of attributes from gamete morphology to species mating systems.
This book is organized into 19 chapters and begins with the conceptualization of sperm competition as a subset of sexual selection and its implications for. ISBN: OCLC Number: Description: x, pages: illustrations ; 25 cm: Contents: Birds as vehicles for sperm competition; avian mating systems and sperm competition; male and female reproductive systems and the fertile period; sperm precedence and mechanisms of sperm competition; copulation behaviour - pair copulation.
Birds do it, bees do it, and they mostly do it more than once. Female promiscuity and male sperm competition are rife in the animal kingdom. Tim Birkhead guides us through the unseen side of the battle of the sexes. He has complete authority within the literature produced by earnest research, and an easy style that conveys his own fascination Cited by: Sperm competition is a form of post-copulatory sexual selection whereby male ejaculates simultaneously physically compete to fertilize a single ovum.
Sperm competition occurs between sperm from two or more rival males when they make an attempt to fertilize a female within a sufficiently short period of time.
This results primarily as a consequence of polyandrous mating systems, or due to extra. A major success of Birkhead & Møller’s book Sperm Competition and Sexual Selection is to have captured something of the excitement being generated by Cited by: 2. In a recent review of the evolution of mate-guarding in birds, Birkhead and Moller (1 ) emphasized the potential reproductive benefits males receive by reducing sperm competition and gave.
Sperm competition and testes size-- Comparative analyses suggest that a variety of ecological and behavioural factors contribute to the tremendous variability in extrapair mating among birds. In an analysis of species of birds, Pitcher et al.
() examined several ecological. Uncovered: the secret sex life of birds For years, people assumed most birds were monogamous. This idyllic image was blown apart when research revealed lifestyles of polygamy, polyandry, marathon mating sessions and sperm competition.
Sperm competition is unimportant in genuine monogamists, and the finding (or confirmed suspicion) that up to 60% of broods in apparently monogamous species have more than one genetic father has. Sperm competition is an intrasexual process in which the sperm from two or more males compete to fertilize a female’s ova.
Sperm Competition and the Evolution of Animal Mating Systems describes the role of sperm competition in selection on a range of attributes from gamete morphology to species mating systems.
This book is organized into 19 chapters and begins with the conceptualization of sperm competition as a subset of sexual selection and its implications for the s: 1. 1. Introduction. Female promiscuity is a prerequisite for sperm competition  and a possible mechanism promoting sexual selection in socially monogamous taxa [2–4].In birds, sperm competition shows high interspecific variation, as indicated by the wide range in extra-pair paternity (EPP) rates (proxy measure of sperm competition) in pair-bonding species [5–7].Cited by: Post-copulatory sexual selection; Sperm competition in birds Sperm competition arises when a single female mates with more than one male (i.e., genetic polyandry).
In. Sperm Competition and Sexual Selection presents the intricate ways in which sperm compete to fertilize eggs and how this has prompted reinterpretations of breeding behavior. This book provides a theoretical framework for the study of sperm competition, which is a central part of sexual selection.
It also discusses the roles of females and the relationships between paternal care in sperm. Research and career. Birkhead's research on promiscuity in birds redefined the mating systems of birds.
 Focusing initially on the adaptive significance of male promiscuity and female promiscuity, he later switched to the study of mechanisms and resolved the mechanisms of sperm competition in provided some of the first evidence of: cryptic female choice in birds Alma mater: Newcastle University (BSc), University of.
