One thousand million years ago, a huge revolution occurred on Earth--sex happened for the first time. From that moment on, the world became ever more colorful and bizarre, ringing with elaborate songs and dances, epic battles, and rallying cries as the desires of males and females collided, generation after generation, in an unbroken chain of sex going back to the dawn of complex life on Earth. Sex is everywhere. Right now warring hordes are locking horns, preening feathers, rampaging lustfully across the savanna, questioning the fidelity of the ones they love.

Naturally occurring salt tolerant and halophytic plants (trees, shrubs, grasses, and forbs) have always been utilized by livestock as a supplement or drought reserve. Salt tolerant forage and fodder crops are now being planted over wide areas. Increasingly, large-scale production of fodder on formerly abandoned irrigated cropland has allowed salt tolerant and halophytic feedstuffs to be mainstreamed into the supply chain for feedlots. Feeding salty feeds to livestock has been evaluated in many countries with good outcomes especially as a way to improve livestock nutrition and...

Golden-winged Warblers (Vermivora chrysoptera) are migratory songbirds that breed in temperate North America, primarily in the Great Lakes region with remnant populations throughout the Appalachian Mountains, and winter in Central and northern South America. Their breeding range has contracted dramatically in the Appalachian Mountains and many populations have dramatically declined, likely due to habitat loss, competition and interbreeding with Blue-winged Warblers (Vermivora pinus), andglobal climate change.. As a result of population declines in much of the eastern portion...

This book is a result of the authors more than 40 years of study on the behavior, populations, and heavy metals in the colonial waterbirds nesting in Barnegat Bay and the nearby estuaries and bays in the Northeastern United States. From Boston Harbor to the Chesapeake, based on longitudinal studies of colonial waterbirds, it provides a clear picture of the toxic trends and effects of heavy metals in the aquatic environment. The authors take a food web, ecosystem approach to contaminants, using population dynamics, habitat selection, and inputs to the bay to examine metal levels. They also...

Preferences, choices, motivation, and habits of species, flocks, and individual birds are discussed and compared. This book investigates who birds are and why they do what they do. Daily, seasonal, and play activities, creativity, reasoning abilities, problem-solving skills, social interaction, life stages, and communication patterns are described, and a distinction is made between vocalizations that are learned and those that are inherited. The behavior and intelligence of both...

A persistent argument among evolutionary biologists and philosophers revolves around the nature of natural selection. Evolution by Natural Selection: Confidence, Evidence and the Gap explores this argument by using a theory of persistence as an intentional foil to examine ways in which similar theories can be misunderstood. It discusses Charles Darwin s theory of natural selection, including what the theory says, what it aims to explain, and how it manages to explain natural selection.

Darwin s theory is so familiar today that it feels universally understood. However, the...
