Efectos del herbicida glifosato sobre la estructura y el funcionamiento de comunidades microbianas de dos suelos de plantaciones de olivo
(Asociación Argentina de Ecología, 2012-04-01)
Los herbicidas pueden alterar la estructura y el funcionamiento del suelo mediante efectos directos sobre varios componentes de su microbiota. Muchos autores han encontrado un efecto perjudicial del glifosato sobre la ...
Soybean fungal soil-borne diseases: a parameter for measuring the effect of agricultural intensification on soil health
(Natl Research Council Canada-n R C Research Press, 2014-06)
The aim of this study was to investigate the influence of agricultural intensification on soil microbial diversity, chemical and physical parameters, and the decrease of the incidence of sudden death syndrome (Fusarium ...
Effects of glyphosate and 2,4-D mixture on freshwater phytoplankton and periphyton communities: a microcosms approach
(2018-02)
Glyphosate (G) and 2,4-D herbicides are massively applied in agriculture worldwide and the use of their mixture is currently a very common practice. We carried out two experiments using microcosms under laboratory conditions ...
Metagenomics-based approach for studying and selecting bioprotective strains from the bacterial community of artisanal cheeses
(Elsevier Science, 2020-12-16)
A metagenome-based approach was used to assess the taxonomic affiliation and functional potential for bacteriocin production of the bacterial community in cow's milk artisanal cheeses from Northwestern Argentina. Three ...
Inside the small-scale composting of kitchen and garden wastes: Thermal performance and stratification effect in vertical compost bins
(Pergamon-Elsevier Science Ltd, 2018-06)
Decentralized composting has been proposed as a best available practice, with a highly positive impact on municipal solid wastes management plans. However, in cold climates, decentralized small-scale composting performance ...
Field evidence supports former experimental claims on the stimulatory effect of glyphosate on picocyanobacteria communities
(Elsevier, 2020-01-20)
Glyphosate-based herbicides are the most commonly used herbicide worldwide. Although glyphosate is known to be toxic to aquatic organisms, it can also have stimulatory effects on small-size (ø <2 µm) cyanobacteria (Pcy) ...
Plankton Multiproxy Analyses in the Northern Patagonian Shelf, Argentina: Community Structure, Phycotoxins, and Characterization of Toxic Alexandrium Strains
(Frontiers Media SA, 2018-11)
The extensive Argentine continental shelf supports high plankton productivity and fish catches. In particular, El Rincón coastal area and the adjacent shelf fronts (38.5-42°S, 58.5-62°W) comprise diverse habitats and hold ...
Culture-dependent and -independent methods reveal dominance of halophilic Euryarchaeota in high-altitude Andean lakes
(Inter-Research, 2018-04)
The hypersaline and extreme environments of the so-called high-altitude Andean lakes in the dry central region of the Andes are considered pristine ecosystems of biotechnological interest. By using culture-dependent and ...
Biodiversity of leaf litter fungi in streams along a latitudinal gradient
(Elsevier, 2019-04-15)
Global patterns of biodiversity have emerged for soil microorganisms, plants and animals, and the extraordinary significance of microbial functions in ecosystems is also well established. Virtually unknown, however, are ...
