Glyphosate effects on floristic composition and species diversity in the Flooding Pampa grassland (Argentina)
Abstract: Temperate grasslands of Argentina are extensively grazed by domestic livestock. Primary production follows a seasonal pattern, with maximum vegetation growth in late spring and minimum in winter. During the last decade, winter forage productivity has been encouraged by promoting the growth of cool-season annual grasses through late summer applications of glyphosate. The aim of …
Glyphosate effects on seed bank and vegetation composition of temperate grasslands
Abstract: Intensification of livestock production has led to the increasing input of agrochemicals, mostly herbicides, in natural and semi‐natural grasslands. Glyphosate application shifts vegetation composition of grasslands of the Flooding Pampa region. Consequently, we asked two questions: (1) does the application of glyphosate affect the size, composition and diversity of the seed bank of these …
New evidences of Roundup (glyphosate formulation) impact on the periphyton community and the water quality of freshwater ecosystems
Abstract: Argentina is the second largest world producer of soybeans (after the USA) and along with the increase in planted surface and production in the country, glyphosate consumption has grown in the same way. We investigated the effects of Roundup (glyphosate formulation) on the periphyton colonization. The experiment was carried out over 42 days in …
Glyphosate reduces spore viability and root colonization of arbuscular mycorrhizal fungi
Abstract: Glyphosate is the most widely used herbicide in the world, but its effects on non-target organisms, such as arbuscular mycorrhizal fungi (AMF), are unclear. No studies have been found that made reference to effects of glyphosate on AMF spore viability despite its importance as a source of propagules for the perpetuation and spread of …
