Book Description
La diversidad biológica es fruto de la interacción entre numerosas especies, ya sean marinas, vegetales o animales, a la par que de los muchos factores limitantes que caracterizan el medio que habitan. El análisis multivariante utiliza las relaciones entre diferentes variables para ordenar los objetos de estudio según sus propiedades colectivas y luego clasificarlos; es decir, agrupar especies o ecosistemas en distintas clases compuestas cada una por entidades con propiedades parecidas. El fin último es relacionar la variabilidad biológica observada con las correspondientes características medioambientales. Multivariate Analysis of Ecological Data explica de manera completa y estructurada cómo analizar e interpretar los datos ecológicos observados sobre múltiples variables, tanto biológicos como medioambientales. Tras una introducción general a los datos ecológicos multivariantes y la metodología estadística, se abordan en capítulos específicos, métodos como aglomeración (clustering), regresión, biplots, escalado multidimensional, análisis de correspondencias (simple y canónico) y análisis log-ratio, con atención también a sus problemas de modelado y aspectos inferenciales. El libro plantea una serie de aplicaciones a datos reales derivados de investigaciones ecológicas, además de dos casos detallados que llevan al lector a apreciar los retos de análisis, interpretación y comunicación inherentes a los estudios a gran escala y los diseños complejos.

Book Description
Addressing the growing economic, political, and cultural presence of Asian states in the Arctic region, this timely book looks at how that presence is being evaluated and engaged with by Arctic states and their northern communities. A diverse range of authors addresses the question that underpins so much of this interest in Asian engagement with the northern latitudes: what do Asian countries want to gain from the Arctic?

Book Description
This annual update reports on developments in the global HIV/AIDS epidemic and draws on the most recent data available to give global and regional estimates of its scope and human toll. This edition also includes a special section on women and AIDS. Findings for 2004 include: the total number of people living with HIV reached its highest ever level of an estimated 39.4 million, with numbers rising in every region; 4.9 million new cases during the year and an estimated 3.1 million deaths; globally, just under half of all people living with HIV are women, with the proportion continuing to rise in most regions, particularly in Eastern Europe, Asia and Latin America.
