The Integration of Fire Ecology and Freshwater Ecosystems in North America: Knowledge Gaps and Research Needs

open access: yesGlobal Change Biology, Volume 32, Issue 6, June 2026.
Illustration of key knowledge gaps and pathways linking fire ecology and freshwater ecosystems. Climate change provides the overarching context, interacting with cumulative and cross‐scale effects to shape local freshwater conditions. Within this context, fire characteristics influence three primary pathways within freshwater ecosystems: species and ...

Driving the neural exposome: Latent mobility states from naturalistic GPS data in older adults

open access: yesAlzheimer's &Dementia, Volume 22, Issue 5, May 2026.
Abstract INTRODUCTION Naturalistic driving provides real‐world behavioral indicators of early cognitive and functional changes. This study integrated naturalistic driving GPS trajectories collected from in‐vehicle sensors with points of interest (POIs) to quantify daily environmental engagement among older adults who were cognitively normal at ...

‘Escaping Isn't for Everyone’: Kurdish Smugglers’ Navigational Tactics at Checkpoints in Iran

open access: yesDevelopment and Change, Volume 57, Issue 3, Page 578-598, May 2026.
ABSTRACT This article examines how Kurdish smugglers navigate state and insurgent checkpoints in the borderlands of western Iran. Drawing on ethnographic research, it analyses two key navigational tactics: persin, a form of negotiated passage involving transaction, recognition and the contingent toleration of authority; and jimi, rendered here as ...

Integrated and closed‐loop biorefinery strategies for efficient waste valorization and biofuel production

open access: yesThe Canadian Journal of Chemical Engineering, Volume 104, Issue 4, Page 1656-1676, April 2026.
Abstract Advancements in biofuel production technologies are essential for reducing global dependence on fossil fuels and addressing their overexploitation. Many valuable components of biomass, such as cellulose, hemicellulose, and lignin, remain underused in traditional biorefineries, which typically rely on a single feedstock to produce a primary ...
