Migratory songbirds are disappearing at a frightening rate. By some estimates, we may have already lost almost half the songbirds that filled the skies only 40 years ago. Following the birds on their 10,000-kilometre migratory journey, Bridget Stutchbury looks at the most threatening factors in their extinction, from pesticides, still a major concern decades after Rachel Carson first raised the alarm, to the destruction of vital habitat; from the bright lights and structures in our cities—...

The world's nearly 7,000 species of crabs are immediately recognizable by their claws, sideways movement, stalked eyes, and thick outer shells. These common crustaceans are found internationally, thriving in various habitats from the edge of the sea to the depths of the ocean, in fresh water or on land. Despite having the same basic body type as decapod crustaceans—true crabs have heavy exoskeletons and ten limbs with front pincer claws—crabs come in an enormous variety of...

For decades, conservation and research initiatives in tropical forests have focused almost exclusively on old-growth forests because scientists believed that these “pristine” ecosystems housed superior levels of biodiversity. With Second Growth, Robin L. Chazdon reveals those assumptions to be largely false, bringing to the fore the previously overlooked counterpart to old-growth forest: second growth.Even as human activities result in extensive fragmentation and deforesta...

Penguins have become a standard fixture in both zoos and imaginations for centuries. But beyond the classic tuxedo markings of the Emperor penguin and what we see in childrens cartoons, how much do we really know about these fascinating creatures? How aware are we of the perpetual danger in which these animals find themselves after so many years of environmental abuse on the part of humans? David Salomon has traveled the world photographing and studying the various species and subspecies ...

The successful conservation of bird species relies upon our understanding of their habitat use and requirements. In the coming decades the importance of such knowledge will only grow as climate change, the development of new energy sources and the needs of a growing human population intensify the, already significant, pressure on the habitats that birds depend on. Drawing on valuable recent advances in our understanding of bird-habitat relationships, this book provides the first major revi...
