More pumas (Puma concolor) does not change perceptions: The mismatched response of ranchers to the presence of a top carnivore

open access: yesPeople and Nature, EarlyView.
Abstract Human‐wildlife conflicts (HWCs) are one of the most critical conservation challenges worldwide. Large carnivores are frequently at the centre of these conflicts because of the perceived and real threats they pose to livestock and human safety.

Environmental changes on grass flowering phenological trends (2000–2021)

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Climate change is impacting the flowering of grasses, which in turn impacts the health of people due to allergic reactions triggered by grass pollen. The timing of flowering was studied for 15 grass species across various habitats in the Cordoba region of Spain.

Analysis of the wind response to resolved versus parametrized turbulent orographic drag in high‐resolution simulations

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
This study analyzes the impact of orographic drag on the lower atmosphere over moderately complex terrain using high‐resolution ICON simulations. Numerical simulations explore the effects of parametrizations over moderately complex terrain near the Perdigao experiment site and the Serra da Estrela mountain range by comparing km‐ and 100‐m‐scale ...

Sensitivities of warm conveyor belt ascent, associated precipitation characteristics and large‐scale flow pattern: Insights from a perturbed parameter ensemble

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
Cloud microphysical processes and low‐level moisture availability affect the ascent of the warm conveyor belt (WCB) airstream. We quantify the relative influence of perturbations to uncertain cloud microphysical model parameters and environmental conditions in the lower troposphere on WCB ascent, as well as on associated precipitation characteristics ...

Kriging‐variance‐based multi‐member ensembles of radar–rain‐gauge precipitation estimates: Application in Switzerland

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
We explore the variance of the radar–rain‐gauge combination kriging‐based system “CombiPrecip”, showing that it represents satisfactorily the radar–rain‐gauge precipitation uncertainty around the kriging expected value. We then present a method to generate ensembles out of it, which we find to be very similar in texture with the expected‐value image ...

Temporal and spatial dynamics of a local wind in Japan, “Kiyokawa‐dashi”: Insights from high‐density observations and numerical simulations

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
We studied a renowned local wind in Japan, “Kiyokawa‐dashi,” with a numerical model and high‐density observations at approximately 1‐km intervals. “Kiyokawa‐dashi” typically begins with intense winds descending onto a confined area leeward of a gorge at the initiation stage and expands over the entire plain at the mature stage.

Developing a Climbing Robot for Stay Cable Maintenance With Security and Rescue Mechanisms

open access: yesJournal of Field Robotics, EarlyView.
ABSTRACT The significance of climbing robotic systems for cable maintenance is escalating in both academic research and real‐world applications. As these systems are poised for real‐world deployment, it is imperative to develop security and rescue mechanisms that ensure robots' intrinsic safety and robustness in dealing with uncertainty factors.

Aerial Localization and Navigation for Surveillance of Large, Featureless, GNSS‐Denied Maritime Environments

open access: yesJournal of Field Robotics, EarlyView.
ABSTRACT In this study, we tackle the problem of surveilling a large area over the sea without access to the global navigation satellite system (GNSS) while searching for the known target vessel. The system utilizes an unmanned aerial vehicle (UAV) equipped with long‐range radio frequency (LoRa) localization and an RGB camera to detect the target ...

A Generalized Concept for Clustering Capabilities of Weeding Robots

open access: yesJournal of Field Robotics, EarlyView.
ABSTRACT Agriculture is undergoing a significant transformation process with the help of robots. Weeding robots have made their way into the market, and they play a crucial role in automating the weeding process in the field. This study introduces a generalized concept of autonomy levels for currently available weeding robots in the field as well as a ...

Spatial Analyses for Fine Woody Debris Volume Stock in the Hyrcanian Research Forest of Kheyrood-Kenar [PDF]

open access: yesبوم‌شناسی جنگل‌های ایران
Extended Abstract Background: In the Hyrcanian forests, fine woody debris (FWDs) plays a significant role in providing ecological services. However, their importance is often overlooked in the management and executive sectors. Based on the sustainability
