Soaring migrants flexibly respond to sea-breeze in a migratory bottleneck: using first derivatives to identify behavioural adjustments over time

Movement Ecology, 2023
Background Millions of birds travel every year between Europe and Africa detouring ecological barriers and funnelling through migratory corridors where they face variable weather conditions.

Data from: Aeroecology of a solar eclipse

, 2018
Light cues elicit strong responses from nearly all forms of life, perhaps most notably as circadian rhythms entrained by periods of daylight and darkness.

High-Resolution Spatial Distribution of Bird Movements Estimated from a Weather Radar Network

Remote Sensing, 2020
Weather radars provide detailed information on aerial movements of organisms. However, interpreting fine-scale radar imagery remains challenging because of changes in aerial sampling altitude with distance from the radar.

Radar quantifies migrant concentration and Dawn reorientation at a Great Lakes shoreline

Movement Ecology, 2018
Background Millions of flying migrants encounter the Great Lakes and other large water bodies on long-distance flights each spring and fall, but quantitative data regarding how they traverse these obstacles are limited.

A Weather Radar Ground Clutter Suppression Method Using Adaptive Coherent Pulse Integration

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Ground clutter poses a significant challenge to the accuracy of weather radar products, especially for aeroecology monitoring. Operational weather radar commonly employs a fixed coherent pulse integration (CPI) for clutter suppression.
