Fine‐Tuning a Weather Foundation Model With Lightweight Decoders for Unseen Physical Processes

open access: yesJournal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 4, August 2026.
Abstract Recent advances in AI weather forecasting have led to the emergence of so‐called “foundation models”, typically defined by expensive pretraining and minimal fine‐tuning for downstream tasks. However, in the natural sciences, a desirable foundation model should also encode meaningful statistical relationships between the underlying physical ...

Long‐term reduction of invasive killer shrimp (Dikerogammarus villosus) density following removal of zebra mussel (Dreissena polymorpha) shells and coarse substrate on UK lake beds

open access: yesEcological Solutions and Evidence, Volume 7, Issue 3, July–September 2026.
Working with Citizen Scientists, researchers tested manual removal of coarse cobbles and zebra mussel shells from fine‐sediment lake beds to reduce invasive killer shrimp densities. Killer shrimp use these features for habitat, and after clearing them from 3 × 3 m sections of lakebed, killer shrimp densities were reduced by over 90% in these sections ...

A Framework to Assess Fine‐Resolution Land Use Implications From Global and Regional Human‐Driven Decisions: MIT IGSM‐Demeter

open access: yesJournal of Advances in Modeling Earth Systems, Volume 18, Issue 7, July 2026.
Abstract Land use change driven by human activities has significant environmental consequences that can vary significantly at local scales. However, global coupled human‐Earth system models usually project land use changes at resolutions that are too coarse to provide insights at finer resolutions that are commensurate to climate models and assessing ...

Global Expansion of Ponto‐Caspian Aquatic Invaders: Drivers, Trends and Taxonomic Biases in a Changing World

open access: yesFreshwater Biology, Volume 71, Issue 7, July 2026.
ABSTRACT Biological invasions pose major threats to ecosystems, with aquatic habitats particularly vulnerable due to high connectivity and biodiversity. The Ponto‐Caspian region is widely recognised as a major source of highly invasive non‐native aquatic species, yet a global synthesis of their spatial, taxonomic and temporal invasion patterns has been
