Morphodynamic adjustment in a watershed affected by megafires: Deadman River, British Columbia, Canada

open access: yesEarth Surface Processes and Landforms, Volume 51, Issue 8, August 2026.
The Deadman River watershed (British Columbia, Canada) was severely impacted by the Sparks Lake Fire in 2021. Timelapse photogrammetry reveals sharp post‐fire channel widening and increase in migration rate. Through multispectral remote‐sensing analysis, these morphodynamic changes are related to burn severity affecting the watershed.

Computer Vision–Based Orthorectification and Georeferencing of Aerial Image Sets [PDF]

open access: yes, 2016
Generating a georeferenced mosaic map from unmanned aerial vehicle (UAV)imagery is a challenging task. Direct and indirect georeferencing methods may fail to generate an accurate mosaic map due to the erroneous exterior orientation parameters stored in ...

When wolves aren't enough: revisiting trophic cascades in northern Wisconsin

open access: yesOikos, Volume 2026, Issue 8, August 2026.
Elimination of top predators has allowed large herbivores to flourish in many terrestrial ecosystems, transforming food webs and ecosystem functions. Restoration of large predator communities is hoped to reverse negative effects of this trophic downgrading, but evidence for such effects is elusive.

Flowering out of sync: Climate change alters the reproductive phenology of Terminalia paniculata in the Western Ghats of India

open access: yesPLANTS, PEOPLE, PLANET, Volume 8, Issue 4, Page 1322-1333, July 2026.
Understanding how climate change impacts the plant life cycle is critical for maintaining biodiversity and ecosystem services. Our findings suggest that Terminalia paniculata Roth, a common tropical deciduous tree species in the Western Ghats, is now flowering and fruiting at more scattered times than it used to in the past.
