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,

Using accelerometer‐based behavioural classification to enhance scavenger conservation
Journal of Applied Ecology, Volume 62, Issue 11, Page 2987-3004, November 2025.We provide a tool to help identify vulture feeding hotspots, supporting carcass management efforts to prevent poisoning. Integrated with near real‐time tracking, our model can support global efforts to combat scavenger poisoning. The training dataset, model and codes are provided in a user‐friendly platform, along with a conceptual framework, to ...

Ecosphere, Volume 16, Issue 10, October 2025.Abstract Spatially explicit estimates of species abundance and distribution are increasingly needed to support conservation planning and management across multiple spatial scales. We present a generalized modeling framework that bridges the gap between local studies and regional to national planning by compiling and harmonizing diverse datasets to ...

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
