Slope Stability Analysis and Soil Mechanical Properties of Impact Craters around the Lunar South Pole

open access: yesRemote Sensing
Water ice has been found in the permanently shadowed regions of impact craters around the lunar South Pole, which makes them ideal areas for in situ exploration missions.

Multi‐Species Impacts of Invasive Opuntia Cacti on Mammal Habitat Use

open access: yesEcology Letters, Volume 28, Issue 7, July 2025.
Biological invasions impact ecosystems worldwide, including through changing the behaviour of native species. Here, we used camera traps to investigate the effects of invasive Opuntia spp. on the habitat use of 12 mammal species in an internationally important region of mammalian biodiversity.

Microhabitat Segregation of Co‐Existing Nightjar Species in The Gambia

open access: yesEcology and Evolution, Volume 15, Issue 6, June 2025.
We studied the spatial distribution and habitat use of Long‐tailed Nightjar (Caprimulgus climacurus) and Standard‐winged Nightjar (Caprimulgus longipennis) in The Gambia to test the hypothesis of spatial niche partitioning. Our findings reveal that while the species co‐occur at the landscape scale, they avoid each other at finer spatial scales ...

DepthFormer: Depth‐Enhanced Transformer Network for Semantic Segmentation of the Martian Surface From Rover Images

open access: yesEarth and Space Science, Volume 12, Issue 6, June 2025.
Abstract The Martian surface, with its diverse landforms that reflect the planet's evolution, has attracted increasing scientific interest. While extensive data is needed for interpretation, identifying landform types is crucial. This semantic information reveals underlying features and patterns, offering valuable scientific insights.

Effect of Soil Type on Running Performance of Small Lunar Rover

open access: yesAerospace
It is very easy for a small lunar rover to slip on the regolith of the lunar surface and become stuck. Previous studies have quantitatively evaluated the effects of wheel geometry, such as elliptical or eccentric wheels, on the performance of a rover ...

Aquaculture and early life stages of the Hawaiian Potter's angelfish (Centropyge potteri)

open access: yesJournal of the World Aquaculture Society, Volume 56, Issue 3, June 2025.
Abstract The Potter's angelfish (Centropyge potteri), a Hawaiian endemic reef fish, has long been prized in the global aquarium trade, with approximately 9000 individuals collected annually from the wild before Hawai‘i's 2021 ban on commercial aquarium fish collection.

Effects of Subduction Fluids and Fractional Crystallization on the Magnetic Minerals Formation in the Back‐Arc Basin

open access: yesGeophysical Research Letters, Volume 52, Issue 10, 28 May 2025.
Abstract (Titano)magnetite is the major magnetic carrier in igneous rocks, whether it can decode the influence of subduction fluids and fractional crystallization characteristics in back‐arc basins is unclear. Here, we performed petrographic and magnetic analyses on volcanic samples from the Okinawa Trough, with titanomagnetite as the dominant magnetic
