Change of soil carbon storage in monoculture tree plantations across wide environmental gradients: Argentina as a case study
(Elsevier, 2024-01)Forest plantations (through afforestation or reforestation) have been proposed as a valuable option to mitigate carbon (C) emissions. However, high spatiotemporal variation has been observed in soil organic carbon (SOC) ... -
Changes in soil biological properties in different management and tyllage systems in petrocalcic argiudoll
(Elsevier, 2020-12)We analyzed the effect of different tillage systems on soils under different land-use histories, on biological properties of soil during one year. The experiment was carried out at a Petrocalcic Argiudoll of Tres Arroyos ... -
Changes in soil characteristics after six seasons of cereal–legume intercropping in the Southern Pampa
(Elsevier, 2015-04)The Argentine Pampa is one of the most productive agricultural regions in the world, but sole crop management practices have led to soil degradation and losses of soil organic matter. The objective of this study was to ... -
Changes in soil pH and addition of inorganic phosphate affect glyphosate adsorption in agricultural soil
(Wiley, 2022-02)Glyphosate is the most widely used herbicide in Argentina. The strong sorption of glyphosate to the mineral fraction of the soil can be affected by environmental conditions and agricultural management, such as the application ... -
Changes in the aerobic vaginal flora after treatment with different intravaginal devices in ewes
(Elsevier, 2010-11)The objective of this study was to characterize the vaginal bacterial flora and subsequent pregnancy rates after AI in sheep subjected to 4 different estrous synchronization regimes – the use of two intravaginal devices ... -
Changes in the vaginal microbiota in ewes after insertion of intravaginal sponges at different stages of the oestrous cycle
(2018)The aims of this study were to determine if the ewe’ vaginal bacterial load differs according to the stage of the oestrous cycle; and thus, if the stage of the oestrous cycle when intravaginal sponges (IS) used for ... -
Changes in Weed Communities of Spring Wheat Crops of Buenos Aires Province of Argentina
(2014-03)During 2004 to 2008, weed surveys were conducted in 373 wheat fields of two different cropped areas (southwest [SW] and southeast [SE]) of the southern region of Buenos Aires Province of Argentina where different weed ... -
Characterization of a deletion in the Hsp70 cluster in the bovine reference genome
(Wiley Online Library, 2017-07-11)The 70 kilodalton heat shock proteins (Hsp70) are highly conserved molecular chaperones which have a crucial role in the stress response of the cell. In mammals, the Hsp70 proteins are encoded by a cluster of three genes: ... -
Characterization of CD79acy + cells in placentas from ruminants
(Elsevier, 2019-11)Previous work carried out to characterise different immune cells in ruminant placentas found strong CD79αcynuclear labelling in cells histologically resembling trophoblast cells. In the attempt to characterize this ... -
Characterization of experimental cattle populations from Argentina with a low-density SNP genotyping panel
(Wiley, 2022-12-05)The objectives of the present experiment were to evaluate a low-density SNP array designed for the molecular characterisation of gene banks and to assess the genetic diversity and population structure of beef cattle herds ... -
Characterization of Immune Cell Infiltration in the Placentome of Water Buffaloes (Bubalus bubalis) Infected with Neospora caninum During Pregnancy
(Elsevier, 2014-05)Neospora caninum infection in cattle stimulates host immune responses, which may be responsible for placental damage leading to abortion. Susceptibility of water buffaloes (Bubalus bubalis) to neosporosis is not well ... -
Characterization of the first bovine gammaherpesvirus 4 strain isolated from an aborted bovine fetus in Argentina
(Springer Verlag, 2020-01-24)Bovine herpesvirus 4 (BoHV-4) is increasingly believed to be responsible for several disorders of the bovine reproductive tract. The first characterization of BoHV-4 in Argentina was from samples from an aborted fetus. ... -
La chinche diminuta Nysius simulans: plaga emergente en quinua y otros cultivos en el valle bonaerense del Río Colorado
(Departamento de Agronomía, Universidad Nacional del Sur, 2015-12)A partir de fines de noviembre, principios de diciembre de 2014, en la zona de riego del valle inferior del Río Colorado, se observó la “chinche diminuta”, en quinua como en otros cultivos y en plantas espontáneas. -
Chlamydia pecorum : fetal and placental lesions in sporadic caprine abortion
(2016)Chlamydial abortion in small ruminants is usually associated with Chlamydia abortus infection. Although Chlamydia pecorum has been detected in aborted ruminants and epidemiological data suggests that C. pecorum is abortigenic ... -
Chlorophyll meter for the evaluation of potato N status
(Springer, 2013-08)Here, we propose a new approach to determine the level of plant N nutrition, based on the relationship between chlorophyll meter (CM) readings and total biomass in potato plants. The objectives of this work were i) to ... -
Cholesterol and desmosterol incorporation into ram sperm membrane before cryopreservation: Effects on membrane biophysical properties and sperm quality
(Elsevier, 2020-09)Ram sperm are particularly sensitive to freeze-thawing mainly due to their lipid composition, limiting their use in artificial insemination programs. We evaluated the extent of cholesterol and desmosterol incorporation ... -
