Group Selection in Predator-Prey Communities. (MPB-9), Volume 9
Many animals regulate their population density by patterns of behavior that would be easy to explain if the forces of natural selection acted to optimize group properties. But Darwinian selection acts on individuals, not groups, and most simple theories have shown group selection to be too slow ever to oppose individual selection successfully. In this book Michael Gilpin presents a model, based on predator-prey dynamics, wherein nonlinear effects are important, so that small advantages to the selfish individual are nonlinearly amplified into disaster for his group. The result is that group selection can be rapid and powerful. Of course many instances of apparent group selection can be explained by kin selection; in other cases, close examination reveals that seemingly altruistic behavior directly benefits the individual genotype as well as the group. The value of the monograph is that it provides a robust model in which group selection, pure and unadulterated, can be seen to work.
Metapopulation Dynamics: Empirical and Theoretical Investigations
Metapopulation Dynamics: Empirical and Theoretical Investigations covers the 1989 proceedings of a metapopulation dynamics workshop held at Lammi Biological Station, Helsinki, Finland. It is divided into 18 chapters that cover various approaches to spatially structured population and community dynamics. After briefly discussing the history of metapopulation ideas and the major conceptual links, the book covers types of studies that have been conducted on single-species and multispecies metapopulations. Then, it examines the relationships between metapopulation dynamics, the equilibrium theory of island biogeography, and the dynamics of populations living in patchy environments. It further ta...
Dodging Extinction
Paleobiologist Anthony D. Barnosky weaves together evidence from the deep past and the present to alert us to the looming Sixth Mass Extinction and to offer a practical, hopeful plan for avoiding it. Writing from the front lines of extinction research, Barnosky tells the overarching story of geologic and evolutionary history and how it informs the way humans inhabit, exploit, and impact Earth today. He presents compelling evidence that unless we rethink how we generate the power we use to run our global ecosystem, where we get our food, and how we make our money, we will trigger what would be the sixth great extinction on Earth, with dire consequences. Optimistic that we can change this ominous forecast if we act now, Barnosky provides clear-cut strategies to guide the planet away from global catastrophe. In many instances the necessary technology and know-how already exist and are being applied to crucial issues around human-caused climate change, feeding the world’s growing population, and exploiting natural resources. Deeply informed yet accessibly written, Dodging Extinction is nothing short of a guidebook for saving the planet.
Wild Life
Wild Life documents a nuanced understanding of the wild versus captive divide in species conservation. It also documents the emerging understanding that all forms of wild nature—both in situ (on-site) and ex situ (in captivity)—may need to be managed in perpetuity. Providing a unique window into the high-stakes world of nature conservation, Irus Braverman describes the heroic efforts by conservationists to save wild life. Yet in the shadows of such dedication and persistence in saving the life of species, Wild Life also finds sacrifice and death. Such life and death stories outline the modern struggle to define what conservation should look like at a time when the long-established defini...

Skyfall
This is the book of a long storied novel, entitled as 'The Skyfall' containing a few side stories also, certain imaginary scenes, episodes, events and incidences, characters, dialogues and some other very interesting phenomena, underlying a few more fanciful and also to some extent more factual descriptions of life or living pertaining to family and the outward society. It has been divided into two parts. Part 1st is based on 1 to 8 chapters and the Part 2nd covers as many as 9 to 14 chapters in all. This novel is, really speaking, a mixture of tragedy, romance and comedy. Hence, the running spirit of the story looks like a perfect novel because of the fact that I preferred to choose such a ...
Bird versus Bulldozer
An examination of the struggle to conserve biodiversity in urban regions, told through the story of the threatened coastal California gnatcatcher “A well-written and thoroughly researched book. . . . Provides a detailed examination of the struggle to conserve biodiversity in urban areas.”—Susan Catherine Cork, Conservation Biology The story of the threatened coastal California gnatcatcher is a parable for understanding the larger ongoing struggle to conserve biodiversity in regions confronted with intensifying urban development. Because this gnatcatcher depends on vanishing coastal sage scrub in Southern California, it has been regarded as a flagship species for biodiversity protection...
