Book Description
The flightless Mancallinae (Aves, Pan-Alcidae) from the Pacific Ocean are represented by one of the richest fossil records among Charadriiformes. A detailed review of previously published and previously undescribed fossils referred to Mancallinae resulted in taxonomic revision of the clade and the identification of three new species from the Miocene and Pliocene of California, USA. This monograph includes descriptions of new Mancallinae species and provides the first species-level phylogenetic hypothesis of Mancallinae relationships. Phylogenetic hypotheses were generated through the combined analysis of molecular sequence data and newly identified morphological character data for extant and extinct charadriiforms. The results of the combined phylogenetic analysis places hypotheses regarding the ethology and morphological convergence of Mancallinae to other flightless wing-propelled divers in phylogenetic context and facilitates comparisons between alcid paleodiversity and paleoclimatic events that have been hypothesized as drivers of alcid evolution.

Book Description
Biology of Marine Birds provides the only complete summary of information about marine birds ever published. It analyzes their breeding biology, ecology, taxonomy, evolution, fossil history, physiology, energetics, and conservation. The book covers four orders of marine birds in detail and includes two summary chapters that address the biology of shorebirds and wading birds and their lives in the marine environment. Summary tables give detailed information on various aspects of their life histories, breeding biology, physiology and energetics, and demography. It provides a guide to ornithologists and students for research projects.

Book Description
Marine phosphorites, the principal raw material for phosphatic fertilizers, do not occur uniformly through time and space. The origin of these unusual sedimentary rocks appears to be related mainly to marine biological productivity, often associated with upwelling currents during certain intervals of geological time. This book examines the environmental setting and resulting phosphorites which formed during the Miocene, one of the major and most recent phosphogenic periods throughout the geologic record. In addition, an oceanographic perspective is given by investigations of modern oceanic environments where phosphorites are presently forming. Together, the geologic and marine approaches provide a complete outlook on this important mineral resource. This book is the third of four reference volumes which together cover the achievements of the International Geological Correlation Programme Project 156 (Phosphorites) during the ten years of the project's existence.
