Modeling long‐term population viability to inform recovery of a functionally extinct urban Blanding's turtle population

The Journal of Wildlife Management, Volume 90, Issue 5, July 2026.
We used a population viability analysis to evaluate the influence of headstarting on recovery of the Rouge National Urban Park Blanding's turtle population. Completing the remaining 12 years of the 20‐year headstarting program is projected to approximately double population size relative to no further supplementation.

Some aspects of the last glaciation in the Mazury Lake District (north-eastern Poland)

Acta Palaeobotanica, 2013
The morphology of the Mazury Lake District (north-eastern Poland) dates from 24-19 ka (main stadial of the youngest Vistulian glaciation). During this last glacial maximum (MIS 2) a belt with lacustrine basins was formed when the ice sheet retreated at ...

Tracing methane sources in shallow waters of the North Sea: Biogenic signatures and hydrocarbon transport near abandoned wells

Limnology and Oceanography, Volume 71, Issue 7, July 2026.
Abstract Numerous abandoned wells in the North Sea may provide gas, particularly methane (CH4), migration pathways by penetrating shallow, biogenic gas accumulations. However, related sampling campaigns have been largely contradictory and lack a substantial database. Research cruise MSM98 targeted the abandoned wells B18‐1, DOK 1‐X, B11‐2, THOR and D‐1

Permafrost Distribution in the Canadian Rockies: Key Variables Influencing Patch‐Scale Variability

Permafrost and Periglacial Processes, Volume 37, Issue 3, Page 372-390, July/September 2026.
ABSTRACT The spatial distribution of permafrost in mountainous regions is influenced by various factors such as topography, climate, vegetation, and substrate. Despite the existence of comprehensive permafrost maps at national and global levels, they fail to accurately represent the patch‐scale (e.g., < 25 m) permafrost distribution in characteristic ...

Subglacial bed form morphology controlled by ice speed and sediment thickness

Geophysical Research Letters, 2016
Subglacial bed forms (drumlins, ribbed moraines, and megascale glacial lineations) are enigmatic repetitive flow‐parallel and flow‐transverse landforms common in glaciated landscapes.

Capturing the Multi‐Decadal Evolution of Glacier–Permafrost Interactions in a High‐Alpine Environment (Ritord, Western Swiss Alps)

Permafrost and Periglacial Processes, Volume 37, Issue 3, Page 473-497, July/September 2026.
ABSTRACT This study investigates the multi‐decadal evolution of a glacier forefield under permafrost conditions in the Combins Massif (western Swiss Alps). A multi‐method approach based on historical and recent datasets is used to analyze its landform components.

Multiproxy Chronologies of the Hurd Rock Glacier (Livingston Island, South Shetland Islands, Maritime Antarctica): Between the Late‐Stage Stabilization and Flow Deceleration

Permafrost and Periglacial Processes, Volume 37, Issue 3, Page 535-550, July/September 2026.
ABSTRACT The Hurd Rock Glacier, located on Livingston Island (South Shetland Islands archipelago, Maritime Antarctica), is a tongue‐shaped feature composed of angular boulders, displaying transverse ridges and furrows, and featuring lobate structures, which are more prominently developed in its frontal sector.

Morphological Dating of Fluvial Terrace Risers Across Spatial and Temporal Scales

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 7, July 2026.
Abstract Fluvial terraces are valuable terrestrial records of past climatic and tectonic changes. Morphological dating, which quantifies the degradation of the riser between two terraces, offers a relatively simple and cost‐effective alternative to other dating methods.

Modeling Legacy Nitrogen Transport Under Instantaneous, Steady‐State, and Transient Groundwater Flow Conditions

Water Resources Research, Volume 62, Issue 7, July 2026.
Abstract In hydrologic settings where groundwater discharge contributes substantially to surface waters, legacy nitrogen in groundwater can confound surface water nitrogen loads estimated exclusively from current terrestrial sources. Additionally, legacy nitrogen in groundwater can contribute to lagged responses to nitrogen management efforts.
