Home Range and Habitat Selection of the Endangered Red Goshawk (Erythrotriorchis radiatus) Across Australia's Tropical Savannas

open access: yesEcology and Evolution, Volume 16, Issue 8, August 2026.
We used long‐term GPS tracking to quantify home‐range size and habitat selection of the endangered Red Goshawk across tropical savannas of northern Australia. Red Goshawks occupied extensive overall home ranges, with well‐defined core ranges centred on nest sites.

Post‐Event Ground Motion Estimation using Graph Neural Networks

open access: yesEarthquake Spectra, Volume 42, Issue 3, August 2026.
Accurate ground motion (GM) estimates are essential for forensic analysis of structural damage following major earthquakes when direct recordings at the location(s) of interest are unavailable. Contemporary post‐event GM estimation methods often leverage nearby observations to constrain estimates of intensity measures (IMs); however, existing ...

Assessing Fire‐Induced Permafrost Ground Deformation and Environmental Drivers Using Interferometric Synthetic Aperture Radar and Machine Learning

open access: yesEarth and Space Science, Volume 13, Issue 8, August 2026.
Abstract Arctic fires in permafrost landscapes have become more frequent in recent years with record fire years in Eastern Siberia in 2019, 2020 and 2021. The consumption of organic layer and charring of the landscape can deepen active layer and long‐term permafrost ground deformation.

New 2010 Maule Aftershock Catalog Reveals Structure of the Deep Subduction Interface

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 8, August 2026.
Abstract On 27 February 2010, a Mw 8.8 earthquake occurred near Maule in south‐central Chile. The subsequent rapid deployment of a dense network of seismic stations on land was able to capture the first year of its aftershock sequence. Here, we revisit this data set using picking Artificial Intelligence tools, a 3D velocity model of the region and ...

iS‐GNN: Interpolation of Crustal Stress Maps Using a Graph Neural Network Model

open access: yesJournal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 4, August 2026.
Abstract Estimating the orientation of the maximum horizontal stress (SHmax) from sparse and unevenly distributed geophysical observations remains a persistent challenge in tectonic and geomechanical stress studies. Classical interpolation methods often neglect the multiscale tectonic–geological heterogeneity of the crust, leading to biased estimates ...

From Resistivity to Hydraulic Properties: Calibrating a Groundwater Flow Model by Integrating Airborne Electromagnetic and Borehole Data Into a Probabilistic Multi‐Texture Framework

open access: yesWater Resources Research, Volume 62, Issue 8, August 2026.
Abstract Airborne electromagnetic (AEM) surveys offer rapid, cost‐effective subsurface imaging, yet converting their electrical resistivity (ER) models into physically meaningful hydraulic property fields for groundwater models remains a challenge. We develop and demonstrate a data‐driven workflow for an unconsolidated sedimentary aquifer system in ...

Thaw Subsidence of Ice‐Rich Permafrost Near Umiujaq, Nunavik (Québec), Canada: 20 Years of Monitoring Using Ground‐Based Leveling Methods, LiDAR, and UAV Photogrammetry

open access: yesJournal of Geophysical Research: Earth Surface, Volume 131, Issue 8, August 2026.
Abstract Differential thaw subsidence is one of the main effects of ice‐rich permafrost degradation, especially in the discontinuous permafrost zone. Although thawing of ice‐rich permafrost can lead to thermokarst, water ponding, and major damage to critical northern infrastructure, thaw subsidence is not often monitored due to the lack of long‐term ...

Spatial Methods for Quantifying Forest Stand Structure Development: A Comparison Between Nearest-Neighbor Indices and Variogram Analysis

open access: yesForestry sciences, 2003
Insight into forest stand structure is of capital importance for understanding forest ecosystem structure and function. The ability of two spatial methods—based on (1) nearest-neighbor indices and (2) geostatistical variogram analysis—to quantify ...

Spatial Pattern and Competitive Relationships of Moso Bamboo in a Native Subtropical Rainforest Community

open access: yesForests, 2018
Bamboo has invaded native forests worldwide, and its aggressive spread by rhizomes facilitates patch expansion and the eventual replacement of adjacent forests. However, fine-scale studies of the spatial pattern and competitive relationships of bamboo in
