A matter of timing: sagebrush steppe restoration seeding outcomes altered by species responses to warmer spring temperatures and interannual weather variation

Restoration Ecology, EarlyView.
Abstract Introduction Restoration outcomes in cold desert ecosystems like sagebrush steppe are affected by weather variability, particularly during the spring, a critical time period for seedling establishment. Seedling emergence phenology is also highly variable among species in these ecosystems.

Assessing forage mass using smartphone imagery for cereal rye under grazing conditions in Nebraska

Crop, Forage &Turfgrass Management, Volume 12, Issue 1, June 2026.
Abstract Managing grazing efficiency requires reliable and practical tools to estimate forage mass. Traditional methods like clipping, though accurate, are time consuming and labor intensive. In this study, two imaging tools, Canopeo and the Crop Canopy Image Analyzer (CCIA), were evaluated for their efficacy in estimating the forage mass of cereal rye

Transfer Learning for Transformer‐Based Drought Forecasting Across Diverse Precipitation Products in India

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 2, April 2026.
Abstract Effective drought management is critical for agriculture‐based economies like India. This study examines whether a transformer‐based architecture can function as a robust pre‐trained backbone for operational drought forecasting across India. We utilized a pre‐trained transformer model, which was trained on the Indian Monsoon Data Assimilation ...

Institutionalisation and Institutional Evolution: A Model of Selecting Government Officials in Ancient China

Economics of Transition and Institutional Change, Volume 34, Issue 2, Page 359-367, April 2026.
ABSTRACT The evolution of institutions in selecting government officials in ancient China reflected efficiency considerations and increased power concentration in the hands of the ruler. Selecting government officials in ancient China became more rule‐based over time, and standardisation and centralisation were some key features of this process.

Leaf gas exchange measurement for steady‐state stomatal conductance model calibration

New Phytologist, Volume 250, Issue 1, Page 672-690, April 2026.
Summary Stomatal conductance models are essential components of crop and land surface models, but collecting data to calibrate them remains challenging due to large leaf‐to‐leaf variability, slow stomatal kinetics, and a lack of consistent measurement protocols, leading to unknown reliability and representativeness of calibrated model parameter ...
