      Simple Summary The main objective of this work was to evaluate the degree of association that exists between three fecal indices (concentrations of 2,6 diaminopimelic acid, nitrogen, and phosphorus) and biomarkers of ruminal ...
    • Use of modified atmosphere packaging in minimally processed and sous vide products 
      Escalona Contreras, Víctor (Facultad de Agronomía de la Universidad de la República, 2017)
      Minimally processed and sous vide vegetables are highly susceptible to deterioration and to be re-contaminated by microbial organisms after the completion of the industrial processing. Modified atmosphere packaging (MAP) ...

      Guajardo, Verónica; Gainza Cortés, Felipe; Meza, Pablo; Álvarez, Catalina; Prieto, Humberto; Sagredo, Boris; Hinrichsen, Patricio; Muñoz, Carlos (International Society for Horticultural Science, 2017)
      The use of molecular markers to complement phenotypic selection has potential for making both scion and rootstock breeding programs more efficient. Additionally, molecular markers can be used for cultivar identification ...
    • Using a dynamic forest model to predict tree species distributions 
      Gutierrez Ilabaca, Alvaro; Snell, Rebecca; Bugmann, Harald (WILEY-BLACKWELL, 2016)
      Aim It has been suggested that predicting species distributions requires a processbased and preferably dynamic approach. If dynamic models are to contribute towards understanding species distributions, uncertainties ...
