This timely book revisits cryptic female choice in arthropods, gathering detailed contributions from around the world to address key behavioral, ecological and evolutionary questions. The reader will find a critical summary of major breakthroughs in taxon-oriented chapters that offer many new perspectives and cases to explore and in many cases unpublished data. Many groups of arthropods such as spiders, harvestmen, flies, moths, crickets, earwigs, beetles, eusocial insects, shrimp and crabs are discussed. Sexual selection is currently the focus of numerous and controversial theoretical and experimental studies. Selection in mating and post-mating patterns can be shaped by several different mechanisms, including sperm competition, extreme sexual conflict and cryptic female choice. Discrimination among males during or after copulation is called cryptic female choice because it occurs after intromission, the event that was formerly used as the definitive criterion of male reproductive success and is therefore usually difficult to detect and confirm. Because it sequentially follows intra- and intersexual interactions that occur before copulation, cryptic female choice has the power to alter or negate precopulatory sexual selection. However, though female roles in biasing male paternity after copulation have been proposed for a number of species distributed in many animal groups, cryptic female choice continues to be often underestimated. Furthermore, in recent years the concept of sexual conflict has been frequently misused, linking sexual selection by female choice irrevocably and exclusively with sexually antagonistic co-evolution, without exploring other alternatives. The book offers an essential source of information on how two fields, selective cooperation and individual sex interests, work together in the context of cryptic female choice in nature, using arthropods as model organisms. It is bound to spark valuable discussions among scientists working in evolutionary biology across the world, motivating new generations to unveil the astonishing secrets of sexual biology throughout the animal kingdom.
"The Politics of Social Cohesion considers in greater detail the impact of immigration on social cohesion and egalitarian redistribution. First, it critically scrutinizes an influential argument, according to which immigration leads to ethnic diversity, which again tends to undermine trust and solidarity and so the social basis for redistribution. According to this argument, immigration should be severely restricted. Second, it considers the suggestion that, in response to worries about immigration, states should promote a shared identity to foster social cohesion in the citizenry"--
Global climate governance has presented problems that have led to failures, yet it has also opened the door to new transregional governance schemes, especially in North America. This book introduces an environmental dimension into the concept of governance. Almost fifteen years after the climate global governance concept emerged, results worldwide have not been as favorable as expected. This book details previous discussions about the concept of global climate governance and its limits. It highlights how the Kyoto Protocol has a limited design taking into account a national approach to global, regional, and transnational problems, had no obligatory mechanisms for implementation and explains the emergence of new polluters not committed under it such as China and India. Furthermore this book explores other levels of authority such as regional institutions - the North American agreement on trade (NAFTA) and on environment (NAAEC), as well as the regional energy working group (NAEWG). The author puts forward a theoretical proposal for re-territorialization and coordination of policies for climate change into new forms of articulating interests in what she terms transnational green economic regions (TGERs) and tests this on two case studies - the Regional Greenhouse Gas Initiative (RGGI) and the Western Climate Initiative (WCI). This study presents the challenges and opportunities of a transregional approach in North America.
Designed for students from a wide range of backgrounds, this text takes a chronological and interdisciplinary approach to human development. With its focus on context and culture, the 8/E illustrates that the status of human development is inextricably embedded in a study of complex and changing cultures.
