Robotics for Crop Pollination: Recent Advances and Future Direction
Journal of Field Robotics, EarlyView.ABSTRACT There is great interest in alternative pollination strategies for crop production in the face of climate change and perennial threats to the traditional pollination mechanisms. This review explores the potential of robotic pollination as a promising solution to these challenges affecting crop fertilization, agricultural sustainability, and ...

Environmental Stressors Influence Spatial Complexity in a Fluvial Macrophyte meadow
Remote Sensing in Ecology and Conservation, EarlyView.This research investigates the nonlinear relationships between environmental stressors and the fine‐scale spatial complexity of a fluvial macrophytes meadow. The use of multivariate spatial analysis allowed us to identify two major environmental gradients (nutrients and light) and two major complexity gradients (related to abundance and fragmentation).

Feature detection and identification using a sonar-array
Proceedings. 1998 IEEE International Conference on Robotics and Automation (Cat. No.98CH36146), 2002 This work explores techniques for sonar sensor fusion in the context of environmental feature detection and identification for navigation tasks. By detecting common features in indoor environments and using them as landmarks, a robot can navigate reliably, recovering its pose when necessary.

Examining the Role of Economic Complexity and Climate Readiness in the Climate‐Fishing Nexus
Sustainable Development, EarlyView.ABSTRACT This paper investigates the climate‐fisheries association in Gulf Cooperation Council (GCC) nations from 1999 to 2022. A key objective is to explore the role of both the economic complexity index (ECI) and the climate readiness factor (READ) in the climate‐fishing nexus.

Geo2DGS‐SLAM: Geometry‐Driven SLAM With 2D Gaussian Splatting
CAAI Transactions on Intelligence Technology, EarlyView.ABSTRACT Recent advances in SLAM systems based on 3D Gaussian Splatting have enabled dense and photorealistic scene reconstruction. However, 3DGS‐based methods still suffer from limited geometric awareness due to the lack of normal rendering support, view inconsistency and weak depth constraints, ultimately hindering high‐fidelity geometric ...

WAH‐i: Optimising microphone array geometry for customised localisation accuracy
Methods in Ecology and Evolution, EarlyView.Abstract Accurate spatial localisation of free‐flying echolocating bats is foundational for resolving fine‐scale flight and echolocation behaviour, prey interception and spatial decision‐making in natural environments. Acoustic localisation using microphone arrays is widely employed for this purpose, yet array geometries in field studies are typically ...

Movement Responses of Seals During Pile Driving for Offshore Wind Farm Construction
Animal Conservation, EarlyView.Despite rapid growth of the renewable energy industry to meet climate change targets, predictions of population‐level impacts on wildlife are currently hindered by a limited understanding of individual behavioural responses to these developments.
