Paraglacial Rock Slope Adjustment Beneath a High Mountain Infrastructure—The Pilatte Hut Case Study (Écrins Mountain Range, France)

open access: yesFrontiers in Earth Science, 2018
Landslides triggered by shrinking glaciers are an expected outcome of global climate change and they pose a significant threat to inhabitants and infrastructure in mountain valleys.

ROCK GLACIER MONITORING USING AERIAL PHOTOGRAPHS: CONVENTIONAL VS. UAV-BASED MAPPING – A COMPARATIVE STUDY [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2018
Rock glaciers are creep phenomena of mountain permafrost. Typically, these landforms look like lava flows from a bird’s eye view. Active rock glaciers move downslope with flow velocities in the range of few centimeters to several meters per year.

Very low inheritance in cosmogenic surface exposure ages of glacial deposits: A field experiment from two Norwegian glacier forelands [PDF]

open access: yes, 2017
Terrestrial cosmogenic nuclide dating has been widely used to estimate the surface exposure age of bedrock and boulder surfaces associated with deglaciation and Holocene glacier variations, but the effect of inherited age has been rarely directly ...

Synthesis and characterization of a highly hydrophilic nanocomposite for wettability alteration, water/oil interfacial tension reduction, and enhanced oil recovery

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Mechanism of wettability alteration, interfacial tension reduction, and oil recovery by novel nanocomposite. Abstract The development of stable nanofluids (NFs) for enhanced oil recovery (EOR) relies on optimizing interactions between reservoir rocks and fluids.

Glacial and periglacial landforms and their recent dynamics in the Las Veguitas catchment, Cordillera Frontal of the Andes (Argentina)

open access: yesFrontiers in Earth Science
The semi-arid Andes of South America are characterized by large areas with glacial and periglacial environments. This study focuses on the distribution and recent dynamics of glacial and periglacial landforms in the Las Veguitas catchment (3000–5500 m ...

Multi-Annual Kinematics of an Active Rock Glacier Quantified from Very High-Resolution DEMs: An Application-Case in the French Alps

open access: yesRemote Sensing, 2018
Rock glaciers result from the long-term creeping of ice-rich permafrost along mountain slopes. Under warming conditions, deformation is expected to increase, and potential destabilization of those landforms may lead to hazardous phenomena. Monitoring the

First ground penetrating radar survey on Monte Perdido glacier (Pyrenees) [PDF]

open access: yes, 2016
Producción CientíficaThe project “The Monte Perdido Glacier: Monitoring the glacial dynamic and the associated cryospheric processes as indicators of global change” (National Park´s 2013 Fund) aims to study the recent dynamic and degradation of this ice

Heterozygous Med13l mice recapitulate a developmental growth delay and craniofacial anomalies seen in MED13L syndrome

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Background Gene transcription is crucial for embryo and postnatal development and is regulated by the Mediator complex. Mediator is comprised of four submodules, including the kinase submodule (CKM). The CKM consists of MED13, MED12, CDK8, and CCNC.

Glacial dynamics in pre-Alpine narrow valleys during the Last Glacial Maximum inferred by lowland fluvial records (northeast Italy) [PDF]

open access: yes, 2018
During the Last Glacial Maximum (LGM), most of the major glaciated basins of the European Southern Alps had piedmont lobes with large outwash plains; only a few glaciers remained within the valley.

Environmental and geomorphological drivers of frog diversity on islands worldwide

open access: yesEcography, EarlyView.
Island biogeography models primarily rely on island physical features and isolation to explain their biodiversity patterns. While newer models have incorporated functional traits to understand plant distribution, few empirical studies have tried to disentangle geometric constraints from niche‐based processes to predict multiple diversity facets of ...
