Assessment of cold tolerance at early developmental stages and allelic variation at candidate genes in South American rice germplasm
(Springer, 2014-06)Rice is susceptible to cold during early developmental stages. Most tolerant cultivars have been developed for other conditions than those occurring in South America’s rice growing areas, or their grain type is not suitable ... -
Occurrence of glyphosate and AMPA in an agricultural watershed from the southeastern region of Argentina
(Elsevier, 2015-12-01)Glyphosate (GLY) and AMPA concentrations were determined in sandy soil profiles, during pre- and post-application events in two agricultural soybean fields (S1 and S2). Streamwater and sediment samples were also analyzed. ... -
Neospora caninum causes severe economic losses in cattle in the humid pampa region of Argentina
(Springer, 2013-06)This work estimates the economic losses due to Neospora abortions in the humid pampa region of Argentina. The total dairy and beef cattle population at risk of abortion is 1,771,326 and 9,726,684 head, respectively. In ... -
Rolling Pampas agroecosystem: which landscape attributes are relevant for determining bird distributions?
(Springer, 2014-12)Background: Agricultural intensification is among the main factors affecting biodiversity. The Rolling Pampas of Argentina have undergone through a process of landscape transformation and agricultural intensification that ... -
Animal performance, carcass characteristics and beef fatty acid profile of grazing steers supplemented with corn grain and increasing amounts of flaxseed at two animal weights during finishing
(Elsevier, 2015-08)The objective of this study was to determine (1) the effects of increasing flaxseed addition to the corn grain supplemented at finishing to grazing steers on animal performance, carcass characteristics and longissimus ... -
Pollen‐mediated gene flow from a commercial potato cultivar to the wild relative S. chacoense Bitter under experimental field conditions in Argentina
(Wiley, 2013-12)The common potato, Solanum tuberosum ssp. tuberosum (tbr, 2n = 4x = 48; 4EBN), has many closely related wild tuber‐bearing species. Around 28 to 35 of them spontaneously grow in Argentina overlapping, in some areas, with ... -
Nitrogen balance for potato crops in the southeast pampas region, Argentina
(Springer, 2013-01)The aim of this work was to build an N mass balance for the potato crop under irrigation conditions in the southeast pampas (Argentina) as a function of N rate and gravitational water. The experiment was developed in a ... -
Optimization of production of chlamydospores of the nematode-trapping fungus Duddingtonia flagrans in solid culture media
(Springer, 2013-03)The large-scale production of nematophagous fungi as agents of biological control is one of the main challenges to be commercially used. In order to improve growth of microorganism in a culture medium, the addition of ... -
Inflammatory infiltration into placentas of Neospora caninum challenged cattle correlates with clinical outcome of pregnancy
(BMC, 2014-01)Infection with Neospora caninum stimulates host cell-mediated immune responses, which may be responsible for placental damage leading to bovine abortion. The aim of this study was to compare immune responses in the bovine ... -
Development of maternal and foetal immune responses in cattle following experimental challenge with Neospora caninum at day 210 of gestation
(BMC, 2013-10)This study examined the immunological responses of pregnant cattle and their foetuses following an experimental challenge with live Neospora caninum tachyzoites at day 210 of gestation. Animals were bled prior to and weekly ... -
First report of seroprevalence of Toxoplasma gondii and Neospora caninum in dairy sheep from Humid Pampa, Argentina
(Springer, 2013-10)The aim of this study was to describe the occurrence of antibodies to Toxoplasma gondii and Neospora caninum in dairy sheep from the Humid Pampa region, Argentina. Blood samples from 704 dairy sheep belonging to six flocks ... -
Phenotypic characterisation of the cellular immune infiltrate in placentas of cattle following experimental inoculation with Neospora caninum in late gestation
(BMC, 2013-07)Despite Neospora caninum being a major cause of bovine abortion worldwide, its pathogenesis is not completely understood. Neospora infection stimulates host cell-mediated immune responses, which may be responsible for the ... -
Molecular characterization of Apis mellifera colonies from Argentina: genotypic admixture associated with ecoclimatic regions and apicultural activities
(Wiley Online Library, 2018-08)The European honeybee, Apis mellifera L. (Hymenoptera: Apidae), is considered as a main contributor to pollination of important crops and to honey production. Originally, beekeeping in Argentina was performed in an extended ... -
Industrial agriculture and agroecological transition systems: A comparative analysis of productivity results, organic matter and glyphosate in soil
(ScienceDirect, 2018-09-22)The system of industrial agriculture (IA), often implemented on a large scale and with high dependence on the supplies use, is reducing the soil organic matter (SOM) and increasing the glyphosate presence in the environment. ... -
