Beyond Circannual Fattening: Behavioural Flexibility and Sex‐Specific Strategies Enable Coping With High‐Elevation Winters

Ecology and Evolution, Volume 16, Issue 4, April 2026.
Winter at high elevations challenges resident species such as the White‐winged Snowfinch. Circannual‐regulated fat accumulation, along with flexible and sex‐specific movement strategies, likely play a critical role in coping with cold temperatures and unpredictable food, but may be vulnerable to climate change.

Why Size Does Not Matter: Sex Driven Home Range Differences in Brown Bears

Ecology and Evolution, Volume 16, Issue 4, April 2026.
This is a novel anlaysis of unique dataset never find anywhere more than 60 collared free ranging brown bears movement data. ABSTRACT Sex, body size and environmental conditions are key determinants of home range size in large mammals, yet their relative importance within populations remains unclear for many wide‐ranging carnivores such as brown bears.

A cross‐site comparison reveals limited geographic variation in risk avoidance of snowshoe hares

Ecology, Volume 107, Issue 4, April 2026.
Abstract Predation risk induces a myriad of behavioral antipredator responses of prey. However, different antipredator behaviors exhibit different degrees of flexibility within a single prey species. Moreover, how predator species composition and traits interact with the flexibility of particular antipredator behaviors to determine spatiotemporal ...

GeoNav: Enhancing field phenotyping with high‐precision global navigation systems integration in the Field Book mobile application

Crop Science, Volume 66, Issue 2, March/April 2026.
Abstract Field data collection is a key activity in plant breeding, underpinning efforts to develop crop varieties with improved yields, disease resistance, and climate adaptability. Accurately associating data with the correct field plots is critical for selection and genetic improvement but can be challenging, especially in large experiments.

Territorial birds of prey adjust their flight behaviour over the course of the breeding season depending on their breeding success

Journal of Avian Biology, Volume 2026, Issue 2, March 2026.
Flight plays a central role in the life histories of birds but is extremely energy demanding. Reproduction is also associated with high energy demands. We might thus expect to see differences in movement behaviour between individuals that breed successfully, those that breed unsuccessfully, and those that do not breed, assuming that individuals adapt ...

Archipelagic Habitat Use by the Black Wood Pigeon

Ecological Research, Volume 41, Issue 2, March 2026.
Satellite tracking of Black Wood Pigeons in the Izu Islands (2022–2025) revealed frequent interisland movements, with flights ranging from 4 to 170 km. Many individuals dispersed among islands after breeding and returned the following spring, indicating partial migratory or nomadic behavior at the archipelagic scale.

Seasonal to Interannual Cross‐Scale Energy Transfer Variability: Observational Insight From the Santa Barbara Channel

Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract Kinetic energy (KE) transfer between spatial scales contributes to the ocean's energy budget by linking scales of KE supply and KE dissipation. Numerical simulations have indicated that for scales smaller than the baroclinic deformation radius, cross‐scale KE transfer has complex spatial and temporal variability, modulated by mixed layer ...

UAV path planning optimization based on GNSS quality and mission requirements [PDF]

, 2020
One of the most crucial factors for the overall success of an Unmanned Aerial Vehicle (UAV) mission is navigation performance, which is severely affected in Global Navigation Satellite Systems (GNSS) challenging environments.

Living on the Edge: Juvenile Foraging and Adult Breeding Ecology of an Aerial Top Predator in Urban Environments

Ecology and Evolution, Volume 16, Issue 2, February 2026.
We analyzed a combination of GPS tracking data and nest‐monitoring data from an urban population of an opportunistic rodent specialist, the Common Buzzard (Buteo buteo), to analyze how raptors utilize urban landscapes. Buzzards occupied even extreme habitats such as residential areas for foraging and breeding and benefit from lucrative foraging ...
