A Multi‐Scale Approach to Assessing Positioning Accuracy in High‐Density Urban Environments of Hong Kong

Transactions in GIS, Volume 30, Issue 1, February 2026.
ABSTRACT This study examined GPS positioning accuracy in high‐density urban environments using Hong Kong as a representative case study. Through field measurements along 32 testing routes using three GPS devices, we evaluated GPS performance across diverse urban morphologies to assess associations between complex urban characteristics and positioning ...

Drought‐driven foraging adjustments in breeding white storks Ciconia ciconia: GPS tracking insights from two French marshes

Journal of Avian Biology, Volume 2026, Issue 1, January 2026.
In the context of climate change, the increasing frequency of severe meteorological events, such as floods or droughts, is expected to impact various life history traits in organisms, primarily by altering the availability and quality of their trophic resources.

Impacts of Climate Change on the Movement Ecology of an Imperfect Homeotherm

Biotropica, Volume 58, Issue 1, January 2026.
ABSTRACT Rapid, human‐induced climate change has posed significant challenges to wildlife. One key strategy animals use to cope with environmental temperature fluctuations is behavioral thermoregulation. Understanding how climate change is expected to influence animal behavior is crucial for assessing its impact on species survival and informing ...

Wetland location and captive breeding influence trans‐Mediterranean movements in the endangered Marbled Duck (Marmaronetta angustirostris)

Ibis, Volume 168, Issue 1, Page 245-258, January 2026.
Waterbirds distributed in semi‐arid and arid regions seem to have adapted their behaviour to the availability and seasonality of wetlands, increasing their mobility range. The Marbled Duck Marmaronetta angustirostris is a threatened waterbird that shows trans‐Mediterranean movements but these are poorly known.

Individual Variation in Philopatry Is Unrelated to Activity and Space Use in the Undulate Skate Raja undulata

Ecology and Evolution, Volume 15, Issue 12, December 2025.
Consistent individual variation in fine‐scale movement traits is unrelated to movements occurring at larger spatio‐temporal scales in undulate skates (Raja undulata). ABSTRACT Individual variation in behavior is widespread in animals. Movement traits, which describe how individuals interact with their environment, can vary across a range of spatial and

Invasive Deer Demonstrate Species‐Specific Niche Habitat Selection in the Australian Alps

Ecological Management &Restoration, Volume 26, Issue 3, September 2025.
ABSTRACT Australia's invasive deer populations continue to expand in abundance and distribution, yet there is limited information on their movement patterns and habitat preferences. This inhibits the prioritisation of areas for control and conservation protection.

Global self-localization and navigation using 3D-LiDAR for headland turning in vineyards

Smart Agricultural Technology
When using the real-time kinematic global navigation satellite system (RTK-GNSS) in orchards or vineyards, autonomous navigation can be disrupted due to the inability to obtain ambiguity-fixed solutions.

A Dynamic UKF-Based UWB/Wheel Odometry Tightly Coupled Approach for Indoor Positioning [PDF]

The centimetre-level accuracy of Ultra-wideband (UWB) has attracted significant attention in indoor positioning. However, the precision of UWB positioning is severely compromised by non-line-of-sight (NLOS) conditions that arise from complex indoor ...

Fine‐scale spatial risk models to predict avian collisions with power lines

Journal of Applied Ecology, Volume 62, Issue 8, Page 1820-1830, August 2025.
Our study illustrates a framework for using bird movement data to provide insights into avian behaviour and the risk they encounter around power line infrastructure. Electricity delivery industries can use these models to identify the electrical infrastructure that poses the highest risk to avian survival and prioritise mitigation efforts, thereby ...
