In situ aerial bioacoustic monitoring from extremely noisy drone recordings

Methods in Ecology and Evolution, Volume 17, Issue 7, Page 2061-2072, July 2026.
Abstract Aerial bioacoustic monitoring has the potential to transform biodiversity surveys by enabling rapid acoustic sampling across large and inaccessible habitats. However, its application from unmanned aerial vehicles (UAVs) has remained limited because strong rotor self‐noise overwhelms target sounds such as bird vocalisations, compromising the ...

Remotely Piloted Aircraft System and Engineering Management: A Real Case Study [PDF]

, 2018
Photovoltaic energy is one of the most relevant renewable energy due to its fast growth in the last years. The sizes of the solar panels and the solar power plants are also increasing. Therefore, the modern solar plants require new maintenance techniques that ensure the efficiency and rentability.

Adaptation and Response in Drylands: A Dryland Research Agenda and Campaign Strategy

Global Change Biology, Volume 32, Issue 7, July 2026.
The Adaptation and Response in Drylands (ARID) campaign was selected by NASA as a scoping study to develop a research agenda for a dryland field campaign. Here, we detail our ARID science research agenda and implementation plan that were developed based on an extensive community engagement effort in over 160 events with over a thousand scientists, land

Using Drone‐Derived Imagery to Describe Prey Sharing Behaviors in Two Piscivorous Resident Killer Whale Populations

Marine Mammal Science, Volume 42, Issue 3, July 2026.
ABSTRACT Cooperative foraging occurs across diverse taxa and facilitates prey acquisition and social learning, particularly when prey is shared among group members. In Resident killer whales (Orcinus orca ater), prey sharing is central to how individuals acquire salmonid prey, yet current research has relied primarily on boat‐based observations.

The Influence of Territory Quality on Behavioral Activity, Mass Loss, and Tenure in Breeding Male Australian Fur Seals

Marine Mammal Science, Volume 42, Issue 3, July 2026.
ABSTRACT Territory quality is a key determinant of male reproductive success and an important driver of population dynamics in pinnipeds. In Australian fur seals (Arctocephalus pusillus doriferus; AUFS), males rely on pre‐breeding energy reserves to acquire and maintain territories, linking competitive ability to body size and condition.

Remotely Piloted Aircraft Systems for Maritime Surveillance [PDF]

, 2015
Remotely Piloted Aircraft Systems (RPAS) gain increasing interest and use for civil applications. However, regulation for integration in airspace is not harmonised in Europe. Also flying beyond the line of sight (BLOS) is only possible by use of command & control communication through a reliable relay system.

A remotely piloted aircraft system in major incident management: concept and pilot, feasibility study [PDF]

BMC Emergency Medicine, 2015
Major incidents are complex, dynamic and bewildering task environments characterised by simultaneous, rapidly changing events, uncertainty and ill-structured problems. Efficient management, communication, decision-making and allocation of scarce medical resources at the chaotic scene of a major incident is challenging and often relies on sparse ...

Learning to fly: integrating spatial ecology with unmanned aerial vehicle surveys

Ecosphere, 2018
Despite the increasing importance of new survey tools such as unmanned aerial vehicles (UAVs), the implications of how their spatial deployment may interact with species detection errors have not yet been assessed.

Visual-Inertial Method for Localizing Aerial Vehicles in GNSS-Denied Environments

Applied Sciences
Estimating the location of unmanned aerial vehicles (UAVs) within a global coordinate system can be achieved by correlating known world points with their corresponding image projections captured by the vehicle’s camera.
