Los escarabajos de corteza (Coleoptera: Curculionidae: Scolytinae) ocasionan disturbios en los bosques naturales de coníferas del Hemisferio Norte. Se alimentan del floema fresco del hospedante, pueden tener varias generaciones al año y suelen actuar de forma concertada a través de feromonas. En el Hemisferio Sur, estos insectos se han instalado en los países donde se explotan comercialmente las plantaciones de pináceas exóticas: Nueva Zelanda, Australia, Sudáfrica, Chile, Uruguay, Brasil y Argentina. Además del daño directo que ocasionan, estos insectos son vectores de hongos perjudiciales para la industria forestal de la región. Los hongos del orden Ophiostomatales (Ascomycota, Sordariomycetes) son un grupo polifilético de especies, particularmente adaptados a la dispersión por escarabajos de corteza. Su importancia radica en que muchas especies son patógenas y otras provocan daño post-cosecha, el manchado azul de la madera, que reduce el valor comercial de la misma. En los últimos años la forestación en el Uruguay con especies exóticas ha tenido gran expansión, siendo los subproductos de la cadena forestal uno de los principales rubros de exportación. En las plantaciones de Pinus spp. se ha detectado la presencia y expansión de escolítidos de origen exótico. |

ABSTRACT.
Latin America, and particularly, the Rio de la Plata Grasslands (RPG), are one of the regions with the highest rates of land use change worldwide. These changes drastically alter ecosystems energy flows, affecting biodiversity, atmospheric composition, and the ecosystem capacity to provide services. In this work we evaluated the impact of these changes on Net Primary Production (NPP), one of the most important and integrative ecosystem attributes, through the calculation of Human Appropriation of NPP (HANPP), a very complete indicator of human impact on ecosystems. Our results provide a comprehensive and fine grained description of HANPP patterns over an entire biogeographycal region for two periods that encompass a strong agricultural intensification process. We used medium resolution land use maps and NPP estimates from sub-national level agricultural statistics and remotely sensed data modeling. Results show that the human impact on the energy flow in RPG ecosystems reached very high levels compared to other regions of the world. The average appropriation of was 42% of the potential vegetation NPP in 2001/2002 and it increased 4.5% during the last years due to an intense land use changes. Most of the HANPP was explained by harvest rather than by land use changes, mainly in the last period due to crops yield increase and the expansion of double crop system as a common agronomic practice. High HANPP values found were associated to a set of environmental impacts that affect ecosystems sustainability and their ability to provide ecosystem services.
