Variation in responses to temperature in admixed Populus genotypes predicts geographic shifts in regions where hybrids are favored

New Phytologist, Volume 249, Issue 3, Page 1509-1526, February 2026.
Summary Plastic responses of plants to their environment vary as a result of genetic differentiation within and among species. To accurately predict rangewide responses to climate change, it is necessary to characterize genotype‐specific reaction norms across the continuum of historic and future climate conditions comprising a species' range. The North

Robust multitask feature learning with adaptive Huber regressions

Canadian Journal of Statistics, Volume 53, Issue 4, December 2025.
Abstract When data from multiple tasks have outlier contamination, existing multitask learning methods perform less efficiently. To address this issue, we propose a robust multitask feature learning method by combining the adaptive Huber regression tasks with mixed regularization. The robustification parameters can be chosen to adapt to the sample size,

Ruminant feces used as inoculum for the in vitro gas production technique Heces de rumiantes como fuente de inóculo para la técnica in vitro de producción de gases Fezes de ruminantes como fonte de inoculo para a técnica in vitro de produção de gases

Revista Colombiana de Ciencias Pecuarias, 2012
Background: ruminal feed fermentation can be studied through in vitro gas production. However, this technique requires fistulated animals from which to obtain the inoculum, which limits its use. Objective: the objective of this experiment was to evaluate
