(2016-03-30)The aim of this study was to evaluate the frequencies of Neospora caninum horizontal and vertical transmissions in beef cow–calf operations under three different extensive management systems: group A: 0.75 head per hectare ... -
Frequency of Neospora caninum-specific antibodies in bulk milk from dairy farms from Mar y Sierras Dairy Basin, Argentina
(Elsevier, 2021-12)The aim of this study was to describe the prevalence of Neospora caninum based on the detection of specific antibodies in bulk tank milk (BTM) from dairy cattle farms in the Mar y Sierras Basin by using an enzyme-linked ... -
Fresh fruit and vegetables: a world of multiple interactions : the case of the Buenos Aires Central Wholesale Market (BACWM)
(Wageningen University, 2010-12)This research explores ethnographically the everyday social interactions between the ‘users’ of a particular marketplace, the Buenos Aires Central Wholesale Market (BACWM). The ‘users’ of this marketplace are the social ... -
Freshly characterization and storability of mini head lettuces at optimal and abusive temperatures
(Sage Publications, 2016-01)Selection of lettuce varieties less sensitive to quality deterioration and more tolerant to abusive temperatures during handling, transportation, and storage is essential to minimize economical and quality losses that ... -
Frost damage on grain number in wheat at different spike developmental stages and its modeling
(Elsevier, 2019-02)Frosts may damage wheat (Triticum aestivum L.) spikes and severely reduce their yield. The objective of this study was (i) to quantify the level of susceptibility to frost at different spike developmental stages, and (ii) ... -

Functional relationships between wood structure and vulnerability to xylem cavitation in races of Eucalyptus globulus differing in wood density
(Oxford University Press, 2018-02)Wood density can be considered as a measure of the internal wood structure, and it is usually used as a proxy measure of other mechanical and functional traits. Eucalyptus is one of the most important commercial forestry ... -
Functional responses to multiple sequential abiotic stress (waterlogging-drought) in three woody taxa with different root systems and stress tolerance
(Wiley, 2023-06-23)There is generally a trade-off in the resistance to drought and to waterlogging. However, several species are sequentially subjected to both stressors in many environments. We evaluated the ecophysiological strategies to ... -
