Evaluating the impacts and benefits of sheldgeese on crop yields in the Pampas region of Argentina: a contribution for mitigating the conflicts with agriculture
(Elsevier, 2019-07-01)Conflicts between waterfowl and agriculture are common in many nations around the world. However, these birds can also provide a variety of benefits that humanity can obtain from nature. There are three migratory and endemic ... -
Evaluation and comparison of serological methods for the detection of bovine neosporosis in Argentina = Evaluación y comparación de pruebas serológicas para la detección de la neosporosis bovina en Argentina
(Asociación Argentina de Microbiología, 2015-12)Neospora caninum is a protozoan parasite that causes abortion and important economic losses in cattle worldwide. The accurate diagnosis of neosporosis is essential for management and control measures. The aims of this study ... -
Evaluation of different live Salmonella enteritidis vaccine schedules administered during layer hen rearing to reduce excretion, organ colonization, and egg contamination
(Oxford University Press, 2019-01-25)Salmonellosis caused by Salmonella Enteritidis is a widespread zoonosis and poultry products are an important source of infection. This study was carried out to evaluate the protection of different vaccination schedules ... -
Evaluation of frequency of antibodies against toxoplasma gondii, neospora caninum and Sarcocystis spp. and transmission routes in sheep from Humid Pampa, Argentina
(2018)The aim of this study was to describe the frequency of ovine specific antibodies to Toxoplasma gondii, Neospora caninum and Sarcocystis spp. and to estimate different transmission routes of these infections. One hundred ... -
Evaluation of the agricultural production systems simulator simulating Lucerne and annual ryegrass dry matter yield in the Argentine Pampas and south-eastern Australia
(2016)Modelling plant growth provides a tool for evaluating interactions between environment and management of forage crops for pasture-based livestock systems. Consequently, biophysical and farm systems models are becoming ... -
Evidence of genetic diversity within Solanum Lycopersicum L. ‘Platense’ landrace and identification of various subpopulations
(Springer Nature, 2020-06-14)Local varieties and landraces are traditional crops that have evolved over time through adaptation to their natural and cultural environment. They are presently regarded as a valuable genetic reservoir, given that most of ... -
Evidence of Recombinant Isolates of Potato Virus Y (PVY) in Argentina
(Springer Netherlands, 2017-06)In order to make a first approach in the identification of the genetic diversity of Potato virus Y (PVY) in Argentina, 46 PVY isolates from different potato growing regions of Argentina were characterized both, biological ... -
Evolution of grain microbiota during hermetic storage of corn (Zea mays L.)
(Elsevier, 2021-03-17)Respiration of biotic components of the grain ecosystem generates self-modified atmospheres (oxygen reduced and carbon dioxide enriched) during hermetic storage. The effect of temperature, moisture content and modified ... -
Exceptional foraging plasticity in King Penguins (Aptenodytes patagonicus) from a recently established breeding site in Tierra del Fuego, Chile
(Elsevier, 2021-06-05)Animals constantly test the borders of their own ecological niche and tend to expand their range, which is now additionally challenged by global climate change. Following human exploitation throughout the Southern Ocean ... -
Exogenous human OKSM factors maintain pluripotency gene expression of bovine and porcine iPS-like cells obtained with STEMCCA delivery system
(BioMedCentral, 2018-07-27)OBJECTIVES: The use of induced pluripotent stem (iPS) cells as an alternative to embryonic stem cells to produce transgenic animals requires the development of a biotechnological platform for their generation. In this ... -
Exogenous progesterone during in vitro fertilization improves developmental competence of partially cumulus-denuded bovine oocytes
(Elsevier, 2023-11)The progesterone (P4) secreted by cumulus cells has gained attention for its role as a possible physiological inducer of sperm acrosome exocytosis. In mammals, it is generally accepted that fertilization rates of oocytes ... -
Expansión del riego: tipo de suelo, pendiente y calidad de agua en el sudeste de la provincia de Buenos Aires
(Facultad de Agronomía, Universidad Nacional de La Plata, 2022-07-14)El objetivo de este trabajo es caracterizar el área agrícola bajo riego complementario en el Sudeste Bonaerense (SB) en cuanto al incremento del área ocupada, tipo de suelo, pendiente y calidad de agua. Mediante un proceso ... -
Expression of apoptosis-related genes at different stages of BoHV-1 and 5 infection of bovine neural tissue
(Elsevier, 2022-11)Bovine alphaherpesviruses (BoHV) 1 and 5 share many genetic and structural characteristics; however, they differ in their ability to cause encephalitis. Previous research suggests that this difference might be caused by a ... -
Expression of internal reproductive barriers in a germplasm bank accession of the wild potato Solanum chacoense Bitter in three ex situ regeneration cycles
(Springer Nature, 2020-10-07)Wild potatoes (Solanum sp.) are important reservoirs of desirable genes for potato breeding. Most of them are diploid and obligate outcrossers, with both sexual and asexual reproduction. Samples of natural populations are ... -
Expression profile of genes as indicators of developmental competence and quality of in vitro fertilization and somatic cell nuclear transfer bovine embryos
(Plos One, 2014-09)Reproductive biotechnologies such as in vitro fertilization (IVF) and somatic cell nuclear transfer (SCNT) enable improved reproductive efficiency of animals. However, the birth rate of in vitro-derived embryos still lags ... -
Extracting DNA of nematodes communities from Argentine Pampas agricultural soils
(2015)We examined four strategies (Tris/EDTA, sodium dodecyl sulfate, Chelex 100 resin and cetyltrimethylammonium bromide -CTAB-) for extracting nucleic acid (DNA) from communities of nematodes. Nematodes were isolated from ... -
