Permanent cover crop as a strategy to promote soil health and vineyard performance.
ABSTRACT.- Conventional viticulture involves a high use of inputs that negatively impact ecosystem services and biodiversity. Traditionally, vineyards are rainfed systems and vegetation is removed or sprayed with herbicides to avoid excessive competition for water and nutrients. Introducing cover crops can positively promote several ecosystem services and particularly soil and crop health and biodiversity.
Rangeland resilience to droughts:Changes across an intensification gradient.
ABSTRACT.- Aim:The intensification of livestock systems generates structural and functional changes in native grassland, which alter their capacity to respond to disturbances. Our objective was to evaluate the resilience to an extraordinary consecutive-droughts event, across an intensification gradient of livestock systems. Our prediction was that sites with more intensive management (less diverse) will have lower resilience (as resistance and/or recovery) to drought. Location:South-central region of Uruguay.

Biological control of phytopathogens and insect pests in agriculture:an overview of 25 years of research in Uruguay.
ABSTRACT.- Plants grow associated with complex communities of organisms, and their development depends largely on management practices, available nutrients in the soil, environmental conditions, and the balanced equilibrium established among all these factors. In unbalanced environments, diseases, insects, and weeds can decrease agricultural productivity or even destroy crops.

Caracterización de ecotonos entre biomas de bosque y biomas abiertos en un área protegida en Uruguay.
RESUMEN.- La teoría de Estados Alternativos de Biomas (EAB) contribuye a explicar la presencia de biomas abiertos (pastizales, arbustales) en ambientes suficientemente cálidos y húmedos para el desarrollo de biomas de bosque. En estos ambientes se pueden encontrar áreas dominadas por biomas abiertos que, según esta teoría, responden principalmente al fuego y a la herbivoría.
Dónde, cuándo y cómo ocurren grandes incendios en la provincia de La Pampa, Argentina:Una caracterización basada en sensores remotos. [Where, when and how is the occurrence of large fires in La Pampa province, Argentina:A remote sensing characterization.]
RESUMEN.- Los incendios son fenómenos catastróficos, devastadores, peligrosos y costosos para una región. A pesar de su relevancia, se conoce poco sobre su dinámica espacial y temporal en la provincia de La Pampa. El objetivo general de este trabajo fue identificar y caracterizar los incendios -en particular, los más extensos- ocurridos en la provincia de La Pampa durante el período julio 2001-junio 2017 (16 campañas) empleando información provista por sensores remotos. Para ello se utilizó información de focos de calor de MODIS Rapid Response distribuidos por el sistema web FIRMS.
