Soybean frogeye leaf spot [Cercospora sojina] : first weather-based prediction models developed from weather station and satellite data
(2015-06-30)In Argentina, soybean frogeye leaf spot occurs sporadically. However, particularly in the Pampas Region, the incidence and severity of this fungal disease have significantly increased in the last years. In the present ... -
Spatial pattern of Pindó Palm (Syagrus romanzoffiana) recruitment in Argentinian atlantic forest: the importance of tapir and effects of defaunation
(Wiley; Association of Tropical Biology and Conservation, 2014-11)Hunting pressure, fragmentation and deforestation have caused global declines in animal abundance, and the consequences for plant communities are poorly understood. Many large‐seeded plants, for instance, depend on large ... -
Spatially variable hidrologic impact and biomass production tradeoffs associated with Eucaliptus ( E. Grandis) cultivation for biofuel production in Entre Ríos, Argentina
(Wiley, 2021-01-11)Climate change and energy security promote using renewable sources of energy such as biofuels. High woody biomass production achieved from short-rotation intensive plantations is a strategy that is increasing in many parts ... -
SSRs, SNPs and DArTs comparison on estimation of relatedness and genetic parameters’ precision from a small half-sib sample population of eucalyptus grandis
(2016)Simple sequence repeats (SSR) are the most widely used molecular markers for relatedness inference due to their multi-allelic nature and high informativeness. However, there is a growing trend toward using high-throughput ... -
Stability and fragmentation versus demographic expansion: different phylogeographic patterns in closely related sympatric legumes (Senna) from arid and semi-arid zones of mid-latitude South America
(Oxford University Press, 2021-03-01)This is the first comparative research in which phylogeographical patterns and present and palaeoclimatic distribution were investigated in desert plants that inhabit the Argentinian Monte and Chaco biogeographic provinces. ... -
Statistically based soil climate exposure scenarios for aquatic pesticides fate modelling and exposure assessment in the Pampa Region of Argentina
(Wiley, 2022-09-05)Although pesticides are used intensively in Argentina's Pampa region, the possibility of performing an environmental risk assessment (ERA) remains limited due to the absence of readily available databases to run pesticide ... -
Status and challenges of black soils
(FAO, 2022-11-05)Although black soils account for only 8.2 percent of the Global Land Area (FAO, 2022a), they are of paramount importance for food security, as highlighted by the UN Sustainable Development Goal 2 (i.e to end hunger, achieve ... -
