This article analyzes the role of different actors in the spatial configuration of the Saraguro colonization in the Southern Ecuadorian Amazon and the land use changes that occurred due to peasant productive activities. Semi-structured interviews with key informants about the local history and the context of colonization were conducted. Additionall...
Resumen Durante las últimas dos décadas, los incendios se han incrementado en frecuencia e intensidad en diversas partes del mundo. Las principales causas de estos patrones se asocian, tanto a las actividades de uso de suelo como a los cambios en el clima. El Bosque La Primavera es un área natural protegida de gran importancia, por su cercanía a la...
Resumen: De acuerdo con el Panel Intergubernamental sobre el Cambio Climático (PICC), deben reportarse los almacenes y cambios del carbono orgánico del suelo (COS) en el tiempo. El modelo RothC-26.3 (RothC) es uno de los más usados en el mundo para estudiar la dinámica del C en diferentes sistemas. Se evaluó el desempeño del RothC en la simulación ...
Resumen: Las áreas metropolitanas de América Latina transitan por diversos cambios te-rritoriales que se han profundizado durante las últimas décadas. En este estudio se analizan las dinámicas territoriales que han ocurrido en la región noreste del Área Metropolitana de Montevideo, se considera a la segregación territorial y a los territorios estra...
With reference to the dynamics of the central and peripheral forces that generate growth and urban life cycle, and evaluation was made of the level of poverty and the change in coverage and land use in the area of influence of the three urban localities that that make up the metropolitan area of Chihuahua, from the period 2000 to 2010. The most imp...
Resumen Se realizó una evaluación del aumento magnético en muestras recolectadas del polvo urbano asentado sobre diferentes superficies, principalmente vialidades pavimentadas y no pavimentadas, como una estrategia de aproximación indirecta al problema de contaminación ambiental en la ciudad de Mexicali (ciudad de tamaño medio en la frontera México...
Butterfly populations are naturally patchy and undergo extinctions and recolonizations. Analyses based on more than 2 decades of data on California's Central Valley butterfly fauna show a net loss in species richness through time. We analyzed 22 years of phenological and faunistic data for butterflies to investigate patterns of species richness ove...

Substantial declines in farmland biodiversity have been reported in Europe for several decades. Agricultural changes have been identified as a main driver of these declines. Although different agrienvironmental schemes have been implemented, their positive effect on biodiversity is relatively unknown. This raises the question as to how to reconcile...

Land-use dynamics and climatic gradients have large effects on many terrestrial systems. Exurban development, one of the fastest growing forms of land use in the United States, may affect wildlife through habitat fragmentation and building presence may alter habitat quality. We studied the effects of residential development and temperature gradient...
