Variations in pest bird density in Argentinean agroecosystems in relation to land use and/or cover, vegetation productivity and climate
(CSIRO, 2018-12-05)Context: Changes in environmental conditions may influence bird populations, including pest bird species, and their distribution. In Argentina, particularly in the Pampas region, agricultural expansion has resulted in ... -
Vegetation structure and livestock grazing intensity affect ground-foraging birds in xerophytic forests of Central-East Argentina
(Elsevier, 2022-10)Ground birds are strongly associated with the vegetation structure in natural environments under livestock grazing. Birds that fed on the ground may be the most affected by overgrazing, while those that fed on the shrub ... -
Vertical distribution of root biomass and soil carbon stocks in forage cropping systems
(Springer, 2018-02)Background and aims: Forage cropping systems may differentially affect the vertical distribution of roots and soil organic C stock (C-OM). In annual crops sequences (ACS) and perennial pastures (PP), we assessed the ... -
Water and solar radiation productivity of double-crops in a humid temperate area
(Southern Cross Publishing, 2011-12)The intensification of agricultural systems including sequential double-crops provides a reliable platform to increase the water and solar radiation use in many humid temperate areas of South America, which are predominantly ... -
