| El desarrollo sostenible de una nación no considera separación entre los factores económicos, ecológicos, sociales, políticos y culturales. Al tratarse de la conservación y buen manejo del recurso hídrico, es indispensable la convergencia de dichos factores. En México, es necesaria la construcción de nuevas y mejores relaciones entre la política hídrica y la urbana, dado el deterioro de las fuentes de agua de las que depende la mayor parte de los habitantes. Aquí se argumenta la existencia y aplicación de herramientas de análisis y gestión viables, con las que, es posible generar un modelo de desarrollo urbano acorde con la disponibilidad y sustentabilidad de los recursos naturales para la cuenca del Río de las Avenidas de Pachuca. En forma general, los... |

| El presente estudio se realizó para conocer la variabilidad genética del maíz nativo de diferente origen ecológico (frío, templado y subtropical) para responder ante condiciones de temperatura alta, principalmente; considerando esta como uno de los principales escenarios provocados por el cambio climático que actualmente amenaza a la diversidad del maíz nativo. La valoración del efecto de temperaturas contrastantes sobre la germinación mostró que afectaron la duración del proceso más no la germinación total. La dinámica de acumulación de biomasa en la plántula (BP), mediante la cuantificación de la biomasa en la parte aérea (BPa), en la raíz (BRa), en el mesocótilo (BMe), la biomasa consumida en la respiración (BCR), el pericarpio más los restos del... |

| Biodiversity conservation continues to be a challenging task for societies worldwide. We undertook a resilience assessment to address the following question: What are the ramifications of social-ecological system dynamics for biodiversity governance of a nationally significant landscape? Resilience assessment offers promise for guiding response strategies, potentially enabling consideration of ecological, social, economic, and governance influences on biodiversity-related activities. Most resilience assessments have, however, struggled to effectively incorporate governance influences. We applied a modified version of the Resilience Alliance workbook approach to explicitly address governance influences at each stage of an assessment of internationally... |

| Resilience and vulnerability represent two related yet different approaches to understanding the response of systems and actors to change; to shocks and surprises, as well as slow creeping changes. Their respective origins in ecological and social theory largely explain the continuing differences in approach to social-ecological dimensions of change. However, there are many areas of strong convergence. This paper explores the emerging linkages and complementarities between the concepts of resilience and vulnerability to identify areas of synergy. We do this with regard to theory, methodology, and application. The paper seeks to go beyond just recognizing the complementarities between the two approaches to demonstrate how researchers are actively engaging... |

| This paper provides an overview of what the Millennium Ecosystem Assessment (MA) calls “indirect and direct drivers” of change in ecosystem services at a global level. The MA definition of a driver is any natural or human-induced factor that directly or indirectly causes a change in an ecosystem. A direct driver unequivocally influences ecosystem processes. An indirect driver operates more diffusely by altering one or more direct drivers. Global driving forces are categorized as demographic, economic, sociopolitical, cultural and religious, scientific and technological, and physical and biological. Drivers in all categories other than physical and biological are considered indirect. Important direct drivers include changes in climate,... |
