"Wildlife in a Changing World" presents an analysis of the 2008 IUCN Red List of Threatened Species. Beginning with an explanation of the IUCN Red List as a key conservation tool, it goes on to discuss the state of the world s species and provides the latest information on the patterns of species facing extinction in some of the most important ecosystems in the world, highlighting the reasons behind their declining status. Areas of focus in the report include: freshwater biodiversity, the status of the world s marine species, species susceptibility to climate change impacts, the Mediterranean biodiversity hot spot, and broadening the coverage of biodiversity assessments."
Traditionally, air transport infrastructure in Latin America and the Caribbean (LAC) was exclusively under government ownership and management. Starting in the late 1990s, several Latin American countries implemented innovative public-private partnerships (PPP) that transferred the financing and management of air transport sector infrastructure to the private sector. This book presents the findings of a first-ever, comprehensive study of how LAC region airports have evolved during this notable period of transition in airport ownership. It is an unbiased, positive analysis of what happened, rather than a normative analysis of what should be done to reform the airport sector or to attract priv...
This work tackles the problems of understanding how energy is transmitted and distributed in power-grids as well as in determining how robust this transmission and distribution is when modifications to the grid or power occur. The most important outcome is the derivation of explicit relationships between the structure of the grid, the optimal transmission and distribution of energy, and the grid’s collective behavior (namely, the synchronous generation of power). These relationships are extremely relevant for the design of resilient power-grid models. To allow the reader to apply these results to other complex systems, the thesis includes a review of relevant aspects of network theory, spectral theory, and novel analytical calculations to predict the existence and stability of periodic collective behavior in complex networks of phase oscillators, which constitute a paradigmatic model for many complex systems.
