THE IMPORTANCE OF AGRICULTURAL AVIATION IN PLANT PROTECTION

, 2023
Meeting people's food demands has become one of the most critical concerns that nations are focusing on these days. The world's population is expanding quickly but its geographical area stays the same, despite best efforts. Furthermore, roads, industrial facilities, new settlements, and erosion are all contributing to the progressive loss of ...

Perfluorohexanone for Clean Fire Suppression: Mechanisms, System Design, Applications, and Future Directions

Safety Science and Technology, EarlyView.
Driven by halon and high GWP agent phase out, perfluorohexanone is increasingly deployed in enclosures such as data centers, marine machinery spaces, and industrial process lines. This review summarizes application performance, discharge and distribution design, material compatibility, and byproduct control and maps practical gaps for large volume and ...

Advancements and Challenges in Second‐ and Third‐Generation Biofuels: A Comparative Analysis of Lignocellulosic and Algal Feedstocks

Safety Science and Technology, EarlyView.
ABSTRACT Advanced biofuels derived from nonfood biomass are increasingly recognized as strategic components of low‐carbon energy systems, particularly for sectors where direct electrification remains difficult. Second‐generation biofuels from lignocellulosic residues and third‐generation biofuels from algal and aquatic biomass offer complementary ...

Spraying drones: efficacy of integrating an avian repellent with drone hazing to elicit blackbird flock dispersal and abandonment of sunflower fields

Wildlife Biology, EarlyView.
Multiple management strategies exist to combat bird damage to agriculture. We explored combining two tools, drones as frightening devices and an avian repellent, to assess effectiveness of an integrated method to deter large flocks on complex landscapes. We evaluated the ability of a spraying drone (DJI Agras MG‐1P) deploying Avian Control (i.e. active

Monitoring active osprey nests with drones is more time efficient and less disturbing than conventional methods

Wildlife Biology, EarlyView.
Drones are used to monitor bird nesting sites at less accessible locations, such as on cliffs, human infrastructure, or within the tree canopy. While there are a growing number of studies documenting avian behavioral responses to various drones, there is a continued need to monitor taxa‐specific responses to different drone models. We explored both the

The performance of drones and artificial intelligence for monitoring sage‐grouse at leks

Wildlife Biology, EarlyView.
Accurately monitoring sage‐grouse populations is critical for conservation, yet traditional ground‐based visual surveys face challenges in scalability and consistency, prompting the exploration of innovative drone‐based methodologies enhanced by artificial intelligence.

Thermal‐UAV assisted detection and relocation of roe deer fawns in managed grasslands

Wildlife Biology, EarlyView.
Advancements in modern fodder production have unintentionally increased wildlife mortality during grass mowing operations. Roe deer Capreolus capreolus fawns are particularly vulnerable because they remain motionless as a predator‐avoidance strategy. Unmanned aerial vehicles (UAVs) equipped with thermal sensors offer a promising method for detecting ...

Field evaluations of thermal optics and tracking tunnels for small mammal surveys at airports and grass dominated habitats

Wildlife Society Bulletin, EarlyView.
Small mammal survey tools are needed at airports to help inform aircraft strike‐risk management. We evaluated thermal optics and tracking tunnels as small mammal survey tools. We conclude that thermal optics would not be a viable survey tool for mouse‐sized mammals (19‐41 g) at airfields and other thick grass habitats unless grass height was maintained
