Climate Extremes and Reproductive Phenology: Regional Variability of Hatch Timing in the Subarctic North Pacific

open access: yesGlobal Change Biology Communications, Volume 1, Issue 4, December 2026.
The Gulf of Alaska (GOA) has experienced multiple marine heatwaves (MHWs) from 2014 to 2016 and 2019. Pacific cod hatch timing advanced by 2–4 weeks during and adjacent to MHWs (2018, 2020) at Eastern Kodiak Island, and a persistent southwest gradient with cooler waters, later hatching, and smaller changes in hatch timing during warming was present ...

UAV‐based RGB and multispectral vegetation indices as alternatives to light box‐derived dark green color index for turfgrass color assessment

open access: yesThe Plant Phenome Journal, Volume 9, Issue 1, December 2026.
Abstract Traditionally, turfgrass color has been assessed through visual ratings or light box‐based digital image analysis, methods that are either subjective or labor‐intensive. In this study, we evaluated the potential of unmanned aerial vehicle (UAV)‐based multispectral and red‐green‐blue (RGB) imagery as a high‐throughput alternative for capturing ...

High‐throughput assessment of plant stand establishment, seedling vigor, and light interception in peanut using UAV‐based RGB and multispectral imagery

open access: yesThe Plant Phenome Journal, Volume 9, Issue 1, December 2026.
Abstract In peanut (Arachis hypogaea L.), plant stand establishment, seedling vigor, and canopy growth are key determinants of crop performance; yet traditional ground‐based assessment methods can be destructive, labor‐intensive, and limited in throughput.

Market Systems Integration in Zambia's Aquaculture Sector: A Scoping Review of Value Chains, Supply Chains and Sustainability Challenges

open access: yesAquaculture, Fish and Fisheries, Volume 6, Issue 5, October 2026.
ABSTRACT Aquaculture is increasingly important to food security, nutrition, livelihoods and economic development in Zambia, yet sectoral growth depends on more than production capacity. This scoping review synthesised evidence on Zambia's aquaculture market systems, focusing on value chains, supply chains and persistent evidence gaps.
