Asymmetric Whisker‐Inspired Sensor Pairs for Enhanced Airflow Sensing on Drones

Advanced Intelligent Systems, Volume 8, Issue 9, September 2026.
This work incorporates asymmetric cross‐sections into a whisker‐inspired sensor pair to enhance airflow sensing. By comparing signals between two offset asymmetric whiskers, the system improves flow heading estimation and identifies the presence of fan‐generated wind during quadrotor flight.

Oyster reef habitat characteristics and nekton communities vary with restoration method in a large‐scale project

Ecosphere, Volume 17, Issue 9, September 2026.
Abstract Restoration in coastal ecosystems is revitalizing populations of foundation species that provide valuable habitat to support biodiversity and ecosystem services. The goals of oyster reef restoration include increasing oyster populations and oyster reef ecosystem services such as provision of habitat for commercially and ecologically valuable ...

Invasive mammals disrupt sea–land nutrient inputs over 169 years on subtropical oceanic islands

Ecosphere, Volume 17, Issue 9, September 2026.
Abstract Invasive mammals have severely impacted oceanic islands, reducing or extirpating seabird populations and driving the collapse of nutrient flows with lasting ecosystem effects. We investigated these dynamics on contrasting subtropical oceanic islands in the South Pacific: Rangitāhua, a large island where goats, cats, and rats caused the ...

Effects of wildfire on the distribution of mammals and birds in a working shrub‐steppe landscape

Ecosphere, Volume 17, Issue 9, September 2026.
Abstract The intensity, frequency, and extent of wildfire have increased drastically in the sagebrush (Artemisia spp.) ecoregion within Washington, USA, over the last few decades. Wildfire on this landscape, already modified and fragmented by agriculture and other disturbances, may challenge the persistence of wildlife that depend on continuous ...

Geophysical Surveys and LiDAR Topographic Analysis of the Vallum and Its Wider Landscape at Milking Gap, Hadrian's Wall

Geoarchaeology, Volume 41, Issue 5, September/October 2026.
ABSTRACT We present the results of geophysical surveys and LiDAR analysis of the Vallum and wider landscape at Milking Gap, on Hadrian's Wall. Magnetic gradiometry and Electrical Resistivity Tomography (ERT) surveys were utilised to investigate the landscape context of the Vallum and provide insight into the stratigraphy of the preserved earthworks ...

Using functionally representative bird species and passive acoustic monitoring to model ecological variation across a land use mosaic in a dryland system

Journal of Avian Biology, Volume 2026, Issue 5, September 2026.
Birds, through their wide range of functional traits, can serve as useful indicators of ecological change. Monitoring them across spatial scales has been considerably enhanced through passive acoustic monitoring (PAM) and automated call identification.

Design and development of a pole climbing surveillance robot

, 2011
The cost of installing, monitoring and servicing a fixed camera system can be high and not all areas are in need of constant surveying. The increase in crime in urban areas emphasizes the need for a more effective and efficient surveillance system, as a ...
