This book was released on 2009 with total page 478 pages. Available in PDF, EPUB and Kindle. Book excerpt: Understanding how variation in communication signals is manifested across a species, and how organisms use such signals to discriminate among potential mates, is crucial to understanding how behavioural mechanisms drive or maintain reproductive isolation between populations, and ultimately, speciation. In this body of research I used a molecular phylogenetic framework as a baseline context to evaluate contemporary patterns of divergence in male and female phenotypic attributes potentially used in sexual communication in two lineages of a widespread North American fish, the brook stickleback (Culaea inconstans). My results show that (1) the patterns of genetic and phenotypic variation are largely incongruent across the species range, suggesting that a complex relationship exists between genes, morphology and behaviour in this species, and that (2) pre-mating isolation between the lineages based on visual cues is likely incomplete; strong conservation of female mate assessment strategies---in particular a preference for more vigorously courting males---coupled with uncorrelated divergence in male courtship performance generated asymmetric patterns of assortative mate choice across the lineage divide during preliminary reciprocal mate choice tests. Surprisingly, variation in the linear intensity of one of the most dramatic courtship traits, male nuptial colour, had little influence on female choice decisions and no evidence of predictive relationships between the intensity of male colouration and least two female reproductive benefits (the level of male parental care and early offspring performance) were found. However, female responses to the male nuptial colour signal were strongly influenced by the spectral nature of the surrounding media, suggesting that signal structure has been largely driven by selection based on recognition and detection in a heterogeneous environment. The present findings indicate that sexual communication in the brook stickleback differs substantially from that of closely related stickleback species, and emphasizes the importance of examining geographic divergence in both female preferences and male communication signals in studies designed to elucidate the mechanisms driving, or constraining, reproductive isolation between groups.

Available in PDF, EPUB and Kindle. Book excerpt: It is my hope that this collection of reviews can be profitably read by all who are interested in evolutionary biology. However, I would like to specifically target it for two disparate groups of biologists seldom men tioned in the same sentence, classical ichthyologists and molecular biologists. Since classical times, and perhaps even before, ichthyologists have stood in awe at the tremendous diversity of fishes. The bulk of effort in the field has always been directed toward understanding this diversity, i. e. , extracting from it a coherent picture of evolutionary processes and lineages. This effort has, in turn, always been overwhelmingly based upon morphological comparisons. The practical advantages of such compari sons, especially the ease with which morphological data can be had from preserved museum specimens, are manifold. But considered objectively (outside its context of "tradition"), morphological analysis alone is a poor tool for probing evolutionary processes or elucidating relationships. The concepts of "relationship" and of "evolution" are inherently genetic ones, and the genetic bases of morphological traits are seldom known in detail and frequently unknown entirely. Earlier in this century, several workers, notably Gordon, Kosswig, Schmidt, and, in his salad years, Carl Hubbs, pioneered the application of genetic techniques and modes of reasoning to ichthyology. While certain that most contemporary ichth yologists are familiar with this body of work, I am almost equally certain that few of them regard it as pertinent to their own efforts.

Download or read book The Behaviour of Teleost Fishes written by Tony J. Pitcher and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 559 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is about the behaviour of teleosts, a well-defined, highly successful, taxonomic group of vertebrate animals sharing a common body plan and forming the vast majority of living bony fishes. There are weH over 22000 living species of teleosts, including nearly all those of importance in com mercial fisheries and aquaculture. Teleosts are represented injust about every conceivable aquatic environment from temporary desert pools to the deep ocean, from soda lakes to sub-zero Antarctic waters. Behaviour is the primary interface between these effective survival machines and their environment: behavioural plasticity is one of the keys to their success. The study of animal behaviour has undergone revolutionary changes in the past decade under the dual impact of behavioural ecology and sociobiology. The modern body of theory provides quantitatively testable and experi mentaHy accessible hypotheses. Much current work in animal behaviour has concentrated on birds and mammals, animals with ostensibly more complex structure, physiology and behavioural capacity, but there is a growing body of information about the behaviour of fishes. There is now increasing awareness that the same ecological and evolutionary rules govern teleost fish, and that their behaviour is not just a simplified version of that seen in birds and mammals. The details of fish behaviour intimately reflect unique and efficient adaptations to their three-dimensional aquatic environment.

Download or read book Animal Personalities written by Claudio Carere and published by University of Chicago Press. This book was released on 2013-03-07 with total page 518 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ask anyone who has owned a pet and they’ll assure you that, yes, animals have personalities. And science is beginning to agree. Researchers have demonstrated that both domesticated and nondomesticated animals—from invertebrates to monkeys and apes—behave in consistently different ways, meeting the criteria for what many define as personality. But why the differences, and how are personalities shaped by genes and environment? How did they evolve? The essays in Animal Personalities reveal that there is much to learn from our furred and feathered friends. The study of animal personality is one of the fastest-growing areas of research in behavioral and evolutionary biology. Here Claudio Carere and Dario Maestripieri, along with a host of scholars from fields as diverse as ecology, genetics, endocrinology, neuroscience, and psychology, provide a comprehensive overview of the current research on animal personality. Grouped into thematic sections, chapters approach the topic with empirical and theoretical material and show that to fully understand why personality exists, we must consider the evolutionary processes that give rise to personality, the ecological correlates of personality differences, and the physiological mechanisms underlying personality variation.

Available in PDF, EPUB and Kindle. Book excerpt: The Lateral Line System provides an overview of the key concepts and issues surrounding the development, evolution, neurobiology, and function of the lateral line, a fascinating yet somewhat enigmatic flow-sensing system. The book examines the historical precedence for linking the auditory and lateral line systems, its structure and development, use of the lateral line system of zebrafish as a model system, physical principles governing the response properties of the lateral line, the behavioral relevance of this sensory system to the lives of fish, and an examination of how this information is shaped and encoded by the peripheral and central nervous systems.
