Land Degradation &Development, Volume 37, Issue 14, Page 10440-10463, 30 August 2026.ABSTRACT Landscape fragmentation may influence the spatial distribution and temporal variation of non‐point source (NPS) pollution by altering hydrological processes, pollutant transport pathways, and ecosystem service functions. However, under the combined effects of natural factors (e.g., precipitation, topography) and anthropogenic factors (e.g ...

Geophysical Research Letters, Volume 53, Issue 15, 16 August 2026.Abstract Headwater catchments provide essential water and nutrients to downstream ecosystems. The timing and evolution of their transport is shaped in part by the “invisible” subsurface structure but have been largely unexplored at the watershed scale.

Ecology 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
Earthquake 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 ...

Generalized product-sum variogram models of the data of the Center of Marine Research
Lietuvos Matematikos Rinkinys, 2004 Environmental data usually depends on both spatial and temporal components. Therefore, it is essential to have statistical models to describe how the data vary across space and time.

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