Remote Sensing in Ecology and ConservationStudying nocturnal bird migration is challenging because direct visual observations are difficult during darkness. Radar has been the means of choice to study nocturnal bird migration for several decades, but provides limited taxonomic information. Here,

Using spatiotemporal information in weather radar data to detect and track communal roosts
Remote Sensing in Ecology and ConservationThe exodus of flying animals from their roosting locations is often visible as expanding ring‐shaped patterns in weather radar data. The NEXRAD network, for example, archives more than 25 years of data across 143 contiguous US radar stations, providing ...

Within-Night Variation in Predictor Importance Highlights Dynamic Nature of Bird Migration. [PDF]
Ecol LettBar chart summarising median percent of gain contributed by each predictor type (atmospheric, sampling and terrestrial) for each timestep after sunset for spring (left) and fall (right) bird migration seasons. Predictor types are denoted by different colours.

Structuring the skies: Diel dynamics of migratory animal movement in the lower atmosphere. [PDF]
EcologyAbstract Earth's lower atmosphere is a vital ecological habitat, home to trillions of organisms that live, forage, and migrate through this medium. Despite its importance, this space is seldom considered a primary habitat for ecological or conservation prioritization, making it one of the least studied environments.

Systematic Continental Scale Monitoring by Weather Surveillance Radar Shows Fewer Insects Above Warming Landscapes in the United States. [PDF]
Glob Chang BiolSystematic remote sensed monitoring of insect density in the air shows fewer insects above warming landscapes in the United States. We estimate insect density at continental scales for the first time by leveraging the nationwide network of weather radars.

Weather Radars Reveal Environmental Conditions for High Altitude Insect Movement Through the Aerosphere [PDF]
Remote SensingHigh-flying insects that exploit tropospheric winds can disperse over far greater distances in a single generation than species restricted to below-canopy flight. However, the ecological consequences of such long-range dispersal remain poorly understood.

Shifts in avian migration phenologies do not compensate for changes to conditions en route in spring and fall. [PDF]
EcologyAbstract Several factors are known to affect bird migration timing, but no study has simultaneously compared the effects of temperature, land surface phenology, vegetation greenness, and relative humidity in both spring and fall. In addition, it is unclear whether long‐term shifts in migration phenologies have kept pace with changing climates.

Turbulence: A Significant Role in Clear-Air Echoes of CINRAD/SA at Night
Remote Sensing, 2023 It is commonly believed that clear-air echoes detected by weather radars are caused by atmobios migration. However, clear-air echoes are sometimes inconsistently related to the activity of living creatures.

Aeroscapes and the Sensory Ecology of Olfaction in a Tropical Dry Forest
Frontiers in Ecology and Evolution, 2022 Aeroscapes—dynamic patterns of air speed and direction—form a critical component of landscape ecology by shaping numerous animal behaviors, including movement, foraging, and social and/or reproductive interactions.
