Uncovering Urban Subsurface Life: Faunal Groundwater Diversity in Heritage Hand Pumps and Monitoring Wells of the City of Leipzig

Ecohydrology, Volume 19, Issue 5, July/August 2026.
ABSTRACT The ecological responses of urban groundwater ecosystems to anthropogenic pressures are poorly understood. Historic hand pumps offer a simple and promising access point to this hidden habitat and may facilitate the detection of groundwater fauna.

Modeling 2m air temperatures over mountain glaciers: Exploring the influence of katabatic cooling and external warming [PDF]

, 2015
Air temperature is one of the most relevant input variables for snow and ice melt calculations. However, local meteorological conditions, complex topography, and logistical concerns in glacierized regions make the measuring and modeling of air ...

Trophic status and sedimentation rate as effective indicators of condition in alpine lake restoration

Restoration Ecology, Volume 33, Issue 8, November 2025.
Abstract Introduction Oligotrophic alpine lakes are highly vulnerable to eutrophication and shoreline erosion under intense recreational and livestock pressure. Lake Peñalara serves as a case study to evaluate ecotourism impacts on mountain lakes and their recovery following the implementation of management and restoration measures.

Increased rate of acceleration on Pine Island Glacier strongly coupled to changes in gravitational driving stress [PDF]

, 2009
Pine Island Glacier, Antarctica, has been undergoing several related changes for at least two decades; these include acceleration, thinning and grounding line retreat.

A Multimethod Investigation of the Lake Agnes Rock Glacier, Colorado, USA

Permafrost and Periglacial Processes, Volume 36, Issue 2, Page 217-229, April/June 2025.
ABSTRACT Rock glaciers are important headwater landforms that play a key role in alpine hydrology. North American rock glaciers are estimated to contain the third largest water volume equivalent globally, and over 3800 rock glaciers have been mapped in Colorado alone. However, these features are often overlooked in alpine water budgets.

From anthropogenic toward natural acidification: Effects of future deposition and climate on recovery in a humic catchment in Norway

Ecological Research, Volume 40, Issue 3, Page 352-364, May 2025.
We simulated water chemical acidification and recovery in a humic, forested catchment in Norway. In the transition from anthropogenic to natural acidification in the current era of low acid deposition, climate becomes a more important driver of surface water acidity.

Rock glacier inventories and kinematics (RGIK): guidelines for inventorying rock glaciers: baseline and practical concepts (version 1.0)

, 2023
Between 2018 and 2023, the International Permafrost Association (IPA) Action Group on Rock glacier inventories and kinematics (RGIK) undertook an unprecedented effort to develop widely accepted guidelines for inventorying rock glaciers, including ...

Seasonal and Inter‐Annual Dynamics in Water Quality and Stream Metabolism in a Beaver‐Impacted Drought‐Sensitive Lowland Catchment

Hydrological Processes, Volume 39, Issue 2, February 2025.
Our study highlights the combined effects of hydrogeomorphic (streamflow, slope and beaver dams)—biogeochemical processes, and seasonal characteristics (temperature, light and flow) on water quality and metabolism in lowland headwater streams. ABSTRACT Increasing drought frequency and severity from climate change are causing streamflow to become ...

Response of a marine-terminating Greenland outlet glacier to abrupt cooling 8200 and 9300 years ago [PDF]

, 2011
Long-term records of Greenland outlet-glacier change extending beyond the satellite era can inform future predictions of Greenland Ice Sheet behavior. Of particular relevance is elucidating the Greenland Ice Sheet's response to decadal- and centennial ...
