This book provides new insights into the social behavior of bats - one of the most fascinating topics currently being pursued by researchers. After an introduction reviewing the history of research in bat behavioral ecology, it covers three major themes: bat sociality per se (Part I), bat communication (Part II), and ecological aspects (Part III). Part I offers a concise overview of the social organization and systems of bats, introducing readers to the complexity and dynamics of group structures. Part II is devoted to the innovative field of social communication, focusing on bat...

Following an opening chapter by the late Susumu Ohno on paralogues of sex-determining genes, the five best-studied genes essential for early mammalian gonadal development are portrayed in detail: SF-1 and WT1 and their roles in early events in gonadal development, SRY and SOX9 in testis determination, and the anti-testis gene DAX-1. Subsequent chapters look at the roles of these genes in sex determination in marsupial mammals, birds, reptiles, amphibians and fish, and review the different sex-determining mechanisms, genetic and environmental, that operate in these different vertebrate...

'Cannabinoids' is a broad term covering a group of natural products from Cannabis sativa, one of which locks on to specific receptors - protein molecules on the surface of cells - known as cannabinoid receptors. Over the past decades scientists have found that cannabinoid receptors and their endogenous ligands, the endocannabinoids, are involved in a vast array of physiological functions, including helping to control brain activity, energy metabolism, heart function, the immune system and even reproduction.

In Cannabinoids, Vincenzo Di Marzo has assembled contributions from...

In In the Company of Bears, originally published in hardcover as Out on a Limb, Ben Kilham invites us into the world he has come to know best: the world of black bears.

For decades, Kilham has studied wild black bears in a vast tract of Northern New Hampshire woodlands. At times, he has also taken in orphaned infants-feeding them, walking them through the forest for months to help them decipher their natural world, and eventually reintroducing them back into the wild. Once free, the orphaned bears still regard him as their mother. And one of these bears, now a...
