First published in 1987, this book presents contributions from international authorities reviewing major themes in variant sexuality. Genetic and evolutionary arguments are presented for the preponderance of paraphilia in males, whilst Freudian and psychoanalytic theories are shown to have limited scientific basis. These and other topics are reviewed in an interesting book, which will be of particular value to students of the psychology of sexuality, evolutionary biology and psychiatry, as well as those with a more general interest in the social, behavioural and biological aspects of sexuality.

First published in 1981, this title takes a ‘sociobiological’ approach to the exploration of sexual habits, looking at the fundamental biological nature of humans. The book covers the spectrum of human sexuality, considering love and marriage, variant sexuality and social influences. This is a valuable reissue for any student of sexual psychology or cultural and evolutionary anthropology with an interest in the fundamental influences on human sexuality.

First published in 1987, this book encompasses a broad range interdisciplinary research into homosexuality — displaying a full spectrum of points of view — and, given that the major traditions of modern homosexual research began in Europe, is not restricted to works in English.. In general topics that are densely covered in the literature are presented in this guide selectively, with some less studied topics, such as Economics and Music, fleshed out with signposts to more comprehensive research. It seeks to not only mirror existing publications, but also to stimulate new work by pinpointing neglected themes and methods. This book will be of interest to students of sociology.

First published in 2003, Medieval Iberia: An Encyclopedia, is the first comprehensive reference to the vital world of medieval Spain. This unique volume focuses on the Iberian kingdoms from the fall of the Roman Empire to the aftermath of the Reconquista and encompass topics of key relevance to medieval Iberia, including people, events, works, and institutions, as well as interdisciplinary coverage of literature, language, history, arts, folklore, religion, and science. It also provides in-depth discussions of the rich contributions of Muslim and Jewish cultures, and offers useful insights into their interactions with Catholic Spain. With nearly 1,000 signed A-Z entries and written by renowned specialists in the field, this comprehensive work is an invaluable tool for students, scholars, and general readers alike.

Apomixis is the consequence of a concerted mechanism that harnesses the sexual machinery and coordinates developmental steps in the ovule to produce an asexual (clonal) seed. Altered sexual developments involve widely characterized functional and anatomical changes in meiosis, gametogenesis, and embryo and endosperm formation. The ovules of apomictic plants skip meiosis and form unreduced female gametophytes whose egg cells develop into a parthenogenetic embryo, and the central cells may or may not fuse to a sperm to develop the seed endosperm. Thus, functional apomixis involves at least three components, apomeiosis, parthenogenesis, and endosperm development, modified from sexual reproduction that must be coordinated at the molecular level to progress through the developmental steps and form a clonal seed. Despite recent progress uncovering specific genes related to apomixis-like phenotypes and the formation of clonal seeds, the molecular basis and regulatory network of apomixis is still unknown. This is a central problem underlying the current limitations of apomixis breeding. This book collates twelve publications addressing different topics around the molecular basis of apomixis, illustrating recent discoveries and advances toward understanding the genetic regulation of the trait, discussing the possible origins of apomixis and the remaining challenges for its commercial deployment in plants.
