Marine Polychaete Worms of the New England Region: Families Aphroditidae through Trochochaetidae
Author: Marian H. Pettibone
Publisher:
ISBN:
Category : Polychaeta
Languages : en
Pages : 498
Book Description
The polychaetes of the Atlantic coast of New England are still imperfectly known. The present study attempts to give as complete a representation of the New England polychaete fauna as is now possible, to systematize knowledge of the polychaete species known from this New England region of the American coast, and to furnish keys designed to facilitate their identification.

Transitions Between Sexual Systems
Author: Janet L. Leonard
Publisher: Springer
ISBN: 3319941399
Category : Science
Languages : en
Pages : 363
Book Description
This book focuses on explaining the distribution of sexual systems (simultaneous hermaphroditism, sequential hermaphroditism, environmental sex determination,dioecy, androdioecy, etc.) among taxa, which remains a major challenge in evolutionary biology. Although significant advances have been made for angiosperms, there is not yet a theory that predicts the sexual system for the majority of animal taxa, and other taxa of plants also remain poorly understood. The problem, particularly for animals, is that sexual systems can be very conservative, with whole phyla and classes being characterized by a single sexual system; for example essentially the whole phylum Platyhelminthes is simultaneously hermaphroditic, whereas the Insecta (Hexapoda) and the Tetrapoda among the vertebrates, are exclusively dioecious. Sex allocation theory on the other hand, suggests that sexual systems should be highly responsive to evolution, changing with population density, life span, patterns of resource availability, etc. The book provides an overview of the topic and then presents a series of chapters, each dealing with a taxon with substantial lability in sexual system in order to identify the factors associated with changes in sexual system in each case. By doing so, the authors reveal factors that have not been considered in formal theory but seem to have a major impact on transitions between sexual systems. This book appeals to a wide readership in fields from zoology and evolutionary biology to botany.
