Does competition management improve the ecophysiological response to water shortage of mixed woodland species of North Patagonia?
(Elsevier, 2023-08)
Globally, the increasing forests vulnerability and drought-induced forest mortality events, extended to a larger scale, may have the potential to rapidly alter forest functioning and the provision of ecosystem services. ...
A proposed role for endomembrane trafficking processes in regulating tonoplast content and vacuole dynamics under ammonium stress conditions in Arabidopsis root cells
(Taylor and Francis, 2021-05-06)
Ammonium (NH4+) stress has multiple effects on plant physiology, therefore, plant responses are complex, and multiple mechanisms are involved in NH4+ sensitivity and tolerance in plants. Root growth inhibition is an important ...
The role of glucose in the pathology of EHEC O157: H7
(Cambridge University Press, 2020-04)
The pathogen enterohemorrhagic Escherichia coli (EHEC) O157: H7 is responsible for hemorrhagic
colitis and hemolytic uremic syndrome in humans [1]. During the colonization process in the
gastrointestinal tract, EHEC needs ...
Calidad forrajera de la ingesta caprina, en la meseta central del sur de Mendoza (Argentina) = Forage quality of goat intake, in the South Central Plateau of Mendoza (Argentina) = Qualidade de forragem do consumo de caprinos, no planalto centro-sul de mendoza (Argentina)
(Facultad de Ciencias Veterinarias, Universidad Nacional de La Pampa, 2023-07)
El objetivo del presente trabajo fue conocer la calidad forrajera de la ingesta caprina en un pastizal natural, situado en la Meseta Central del Sur de Mendoza (Argentina). El ensayo se llevó a cabo por simulación de la ...
Three easy fixes for sire use can enhance genetic progress in community-based breeding programmes
(Wiley, 2021)
We analysed options to optimize the use of sires in sheep and goat community-based breeding programmes (CBBP) for three scenarios occurring under field conditions: premature sale of selection candidates, fixed service ...
Converting multi-trait breeding objectives into operative selection indexes to ensure genetic gains in low-input sheep and goat breeding programmes
(Elsevier, 2021-05)
Small ruminant breeding programmes in low-input production systems are best organised at the community level. Participant farmers have to agree on goal traits and their relative importance. When BLUP breeding values of ...
Salinidad por aplicación de vinazas de un suelo subtropical cultivado con caña de azúcar
(Asociación Argentina de la Ciencia del Suelo, 2018)
La producción de bioetanol a partir de caña de azúcar presenta un fuerte desafío de sustentabilidad dado que por la producción de 1 m3 de alcohol, se genera 10-13 m3 del efluente vinaza. Este es un líquido pardo oscuro, ...
Towards environmentally sound intensification pathways for dairy development in the Tanga region of Tanzania
(Springer, 2020-11)
The gap between milk demand and domestic supply in Tanzania is large and projected to widen. Meeting such demand through local production of affordable milk presents an opportunity to improve the welfare of producers and ...
Temperature and day length drive local adaptation in the Patagonian foundation tree species Nothofagus pumilio
(BioRxiv, 2023-04-29)
Climate change alters relationships among environmental conditions and thus has the potential to change the selection pressures acting on adaptive gene variants. Using a landscape genomic approach, we show that the southern ...
Estructura del rastrojo y agua disponible bajo siembra directa en el semiárido austral pampeano
(Asociación Argentina de la Ciencia del Suelo, 2023-06)
Los procesos importantes relacionados con la dinámica del agua ocurren principalmente en la interfase suelo-atmósfera. La estructura de la cobertura de rastrojos de cultivos, tanto por cantidad como su distribución, tiene ...
