Book Description
Freshwater sculpins (Cottus) are common throughout temperate regions of the Northern Hemisphere. Their broad distribution in the Western North America makes them a good model for understanding phylogeographic relationships among western fishes. Within much of the interior west three lineages, C. bairdii, C. confuses, and the C. beldingii complex, are most prevalent. The distribution of these three overlap in the Snake River Basin. All occur below Shoshone Falls on the Snake River. However, only two currently reside in the Upper Snake River above the falls. An exception are the Lost River streams of central Idaho. While these streams are technically part of the Upper Snake River Basin, they do not directly connect with the Snake River. Preliminary studies with a single mitochondrial DNA (mtDNA) gene suggested multiple pathways for Cottus introduction into the Lost River stream complex. Here, three mitochondrial and five nuclear genes were examined to investigate the phylogenetic relationships of these three lineages. Sequences were obtained from 71 different population in the Lost River streams and surrounding basins. Maximum Likelihood (ML) phylogenies were constructed using these data. Our data indicate that relationships among populations within these species are complex and that no single invasion into the Lost River streams and surrounding regions can account for the phylogenetic signals detected. Instead, it appears that multiple invasions in an evolving landscape played a significant role in the modern distribution of species in this region.

Book Description
This collection employs a multi-disciplinary approach treating ancient childhood in a holistic manner according to diachronic, regional and thematic perspectives. This multi-disciplinary approach encompasses classical studies, Egyptology, ancient history and the broad spectrum of archaeology, including iconography and bioarchaeology. With a chronological range of the Bronze Age to Byzantium and regional coverage of Egypt, Greece, and Italy this is the largest survey of childhood yet undertaken for the ancient world. Within this chronological and regional framework both the social construction of childhood and the child’s life experience are explored through the key topics of the definition of childhood, daily life, religion and ritual, death, and the information provided by bioarchaeology. No other volume to date provides such a comprehensive, systematic and cross-cultural study of childhood in the ancient Mediterranean world. In particular, its focus on the identification of society-specific definitions of childhood and the incorporation of the bioarchaeological perspective makes this work a unique and innovative study. Children in Antiquity provides an invaluable and unrivalled resource for anyone working on all aspects of the lives and deaths of children in the ancient Mediterranean world.

Book Description
Ten years have passed since the first edition of this book. During that time the field of bird migration has experienced many advances which are reflected in this second edition. No other book exists to bring together the vast amount of information currently available on the subject of bird migration. Includes discussion of evolution and history of bird migration, physiology, orientation mechanisms and threats to migrations and is accessible to experts as well as amateurs.

Book Description
The 1994 IUCN Red List of Threatened Animals was a major advance on its predecessors in clarity of layout and amount of information presented. This is taken further in the 1996 edition, which is also the first global compilation to use the complete new IUCN Red List category system.

Book Description
Based on the Inaugural Albatross Conference in Hobart in 1995. Thirteen chapters are based directly on conference papers, and ten have been written subsequently. Topics covered include albatross taxonomy, ecology, feeding and breeding habits, population and distribution as well as the effect of human activities on albatross mortality. Examines the conservation of albatrosses and threats to their survival, in particular the incidental mortality associated with long line fisheries. Appraises recent research in albatross biology, ecology and conservation and discusses opportunities for future research.
