Phenomics‐driven insights into zoysiagrass drought resistance using small unmanned aircraft systems (sUAS)‐based hyperspectral images

The Plant Phenome Journal, Volume 8, Issue 1, December 2025.
Abstract The application of small unmanned aircraft systems (sUAS)‐based high‐throughput phenotyping in plant breeding has advanced significantly over the past decade. Hyperspectral images and machine learning approaches offer potential to enhance drought resistance screening in turfgrass. However, large‐scale field applications remain limited, and the

National‐scale terrestrial biodiversity and ecosystem monitoring with essential biodiversity variables in Japan and Finland

Ecological Research, Volume 40, Issue 6, November 2025.
Essential Biodiversity Variables (EBVs) provide a standardized framework for monitoring biodiversity change in line with conservation targets. We assessed terrestrial biodiversity datasets for EBVs in Japan and Finland, and compared Japan's data availability with GEO BON and EuropaBON, identifying both unique strengths and gaps.

Why Does the Norwegian Sea‐Barents Sea Region Have the Smallest Amount of Stratocumulus in Summer?

Geophysical Research Letters, Volume 52, Issue 20, 28 October 2025.
Abstract The melting of sea ice in the Arctic has sparked research into how clouds form in exposed ice‐free zones. This study delves into the seasonal distribution of stratocumulus clouds over the Norwegian Sea‐Barents Sea region and presents a conceptual model for the underlying mechanisms.
