| Los caminos y sus bordes presentan características diferentes al ambiente original que los rodea, que pueden influir sobre las poblaciones de insectos. Para evaluar el grado de asociación de Pogonomyrmex pronotalis, Pogonomyrmex rastratus y Pogonomyrmex inermis con los caminos en el Monte central, medimos la densidad de colonias en el algarrobal y en dos caminos, y estudiamos la dieta y la actividad de estas especies en cada ambiente. La densidad de colonias de Pogonomyrmex pronotalis fue mayor en los caminos, la de Pogonomyrmex rastratus fue menor, y similar en ambos ambientes, y la de Pogonomyrmex inermis fue muy baja en los caminos y aún menor en el algarrobal. La actividad de Pogonomyrmex pronotalis fue mayor en los caminos y superior a las de... |

| Natural disturbances are important components of ecosystem dynamics. Large scale disturbances produced by volcanoes, have been poorly studied because of their low frequency, the lack of baseline studies due to their unpredictability, the impossibility of replication, and the difficulty of conducting long-term studies to monitor ecosystem recovery. The recent eruption of the Puyehue-Cordón Caulle volcanic complex (June 2011), which produced an ash fall covering 24 million ha of Patagonia, provides a unique opportunity of studying this type of disturbance in areas with baseline data. The summer before the ash fall (2011) ant communities were characterized in areas of the Patagonian steppe which were later covered with 4 cm of fine ash. The aim of this study... |

| Firewood can act as a long-distance dispersal vector for wood-infesting insects both within and among countries. Recently, we detected the alien carpenter ant Camponotus mus in firewood transported from central Argentina to Patagonia. This species generates significant economic losses in its native range and has invader potential. Moreover, global warming and the increasing anthropogenic disturbance in Patagonian ecosystems make them highly susceptible to insect invasions. This is especially alarming considering the current lack of sanitary controls of incoming goods into the region. To prevent insect introductions via firewood, it is crucial to implement a joint efort among the scientific community, control organisms, government and end user. |
