The Evolution of Primary Sexual Characters in Animals
Primary sexual traits, those structures and processes directly involved in reproduction, are some of the most diverse, specialized, and bizarre in the animal kingdom. Moreover, reproductive traits are often species-specific, suggesting that they evolved very rapidly. This diversity, long the province of taxonomists, has recently attracted broader interest from evolutionary biologists, especially those interested in sexual selection and the evolution of reproductive strategies. Primary sexual characters were long assumed to be the product of natural selection, exclusively. A recent alternative suggests that sexual selection explains much of the diversity of “primary” sexual characters. A ...
Studies in Crenobiology
Of interest to freshwater biologists, hydrobiologists, entomologists and ecologists, this book covers such topics in the field of crenobiology as the influence of light regime and water chemistry on the structure of forest spring vegetation.

The Great Ordovician Biodiversification Event
Two of the greatest evolutionary events in the history of life on Earth occurred during Early Paleozoic time. The first was the Cambrian explosion of skeletonized marine animals about 540 million years ago. The second was the "Great Ordovician Biodiversification Event," which is the focus of this book. This is the first book devoted specifically to establishing the global patterns of differentiation of Ordovician biotas through time and space. It provides extensive genus- and species-level diversity data for the many Ordovician fossil groups and presents an evaluation of how each group diversified, with assessments of patterns of change, and rates of origination and extinction.
Oceanography and Marine Biology, An Annual Review, Volume 41
Interest in oceanography and marine biology and its relevance to global environmental issues continues to increase, creating a demand for authoritative reviews that summarize recent research. Oceanography and Marine Biology: An Annual Review has catered to this demand since its foundation, by the late Harold Barnes, more than 40 years ago. It is an
