The Application of Autonomous Fixed‐Wing Drones in the Sub‐Antarctic Operating Beyond Visual Line of Sight to Enable Large Area, Multi‐Species Population Monitoring in a Changing Environment

Remote Sensing in Ecology and Conservation, EarlyView.
Autonomous fixed‐wing drones operating beyond visual line of sight of the pilot were used to conduct the first aerial, multi‐species baseline reference survey at the sub‐Antarctic island of South Georgia. Long‐term population monitoring in this remote, challenging environment has historically proved difficult, with terrestrial monitoring generally ...

Exploring Drivers and Mitigation Strategies for Food Manufacturing Wastes in the Circular Economy Using Rich Pictures

Sustainable Development, EarlyView.
ABSTRACT This study aims to identify the main types, drivers, and solutions for food loss and waste (FLW) as reported by stakeholders within the UK food manufacturing sector from a Circular Economy perspective. Based on insights from diagramming‐based workshops involving 35 participants working in an organisation in the sector, FLW occurs primarily as ...

Habitat selection of moose in Sweden in managed boreal forests with Pinus contorta and P. sylvestris

Wildlife Biology, EarlyView.
Human land use can take advantage of using exotic species to increase financial benefits. However, the use of exotic tree species might affect ecosystem functioning, potentially including the habitat use and movement behaviour of animals, modifying their ecological impact, and interactions with human land use.

Study on the Influence of Rigid Wheel Surface Structure on the Trafficability of Planetary Rover on Soft Ground

Aerospace
In order to explore the influence of wheel surface structure on the trafficability of planetary rovers on soft ground, three kinds of wheels with different rigid wheel surface structures were selected for research. The basic performance parameters of the

Integrating large mammalian herbivores into Dynamic Global Vegetation Models: Status and next steps

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Zoogeochemistry, the study of how animals influence elemental cycling within ecosystems, bridges the fields of zoology, ecology and biogeochemistry. Yet, most terrestrial ecosystem models, especially Dynamic Global Vegetation Models (DGVMs), remain largely plant‐centric

Improving engineering models of terramechanics for planetary exploration

Results in Engineering, 2019
This short letter proposes more consolidated explicit solutions for the forces and torques acting on typical rover wheels, that can be used as a method to determine their average mobility characteristics in planetary soils.

From foraging to decomposition: Large vertebrates as biotic drivers of trace element cycling across landscapes

Journal of Animal Ecology, EarlyView.
We highlight an overlooked pathway in ecosystem functioning: the role of animal carcass decomposition in trace element cycling. By linking animal life cycles to landscape‐scale processes, we explain how large animals redistribute scarce elements and influence spatial heterogeneity, with implications for ecosystem functioning and restoration.
