New Schmidt hammer exposure‐age dating calibrations for the Last Glacial Termination in NW Scotland: Development and application to undated Torridon Group sandstone surfaces in Wester Ross

Journal of Quaternary Science, EarlyView.
ABSTRACT An understanding of the terrestrial extent, retreat dynamics and climate–glacier coupling of ice masses during the Last Glacial Termination (LGT, ~18–11 ka) is often limited by a fragmentary geomorphological record and is dependent on precise, accurate and robust dating frameworks.

Radioglaciological studies on Hurd Peninsula glaciers, Livingston Island, Antarctica [PDF]

, 2009
We present the results of several radio-echo sounding surveys carried out on Johnsons and Hurd Glaciers, Livingston Island, Antarctica, between the 1999/2000 and 2004/05 austral summer campaigns, which included both radar profiling and common-midpoint ...

Sensitivity of a distributed temperature-radiation index melt model based on AWS observations and surface energy balance fluxes, Hurd Peninsula glaciers, Livingston Island, Antarctica [PDF]

, 2012
We use an automatic weather station and surface mass balance dataset spanning four melt seasons collected on Hurd Peninsula Glaciers, South Shetland Islands, to investigate the point surface energy balance, to determine the absolute and relative ...

First finding of Icelandic tephra in Czechia: Vedde Ash identified in palaeolake sediments of Stará Jímka

Journal of Quaternary Science, EarlyView.
ABSTRACT In this study, we report the first documented occurrence of the Icelandic Vedde Ash (VA) in the Bohemian Forest, identified within palaeolake sediments from Stará Jímka, Czechia, representing the first Icelandic tephra layer identified in Czechia.

Monitoring wolverine (Gulo gulo) distribution across the western United States for regional and national assessment

The Journal of Wildlife Management, EarlyView.
We estimated the distribution of the federally threatened wolverine (Gulo gulo) across the western United States in 2022, evaluated changes in distribution since 2017 (the last survey), and made inference on drivers of wolverine occurrence. This monitoring program and subsequent results are used by states to make management and conservation decisions ...

The Swedish Arctic Fox Project: 40 years of research in ecology and conservation

The Journal of Wildlife Management, EarlyView.
The 4 central research themes in The Swedish Arctic Fox Project and key deliverables for practical conservation achieved over 4 decades. Abstract The scientific community widely recognizes the value of long‐term studies, especially those with individual‐level resolution; however, maintaining a consecutive data series is associated with multiple ...

Historical data reveal earlier flowering under environmental change

Nordic Journal of Botany, EarlyView.
Global temperatures have risen ~ 1.1°C since the 1800s and the mean annual air temperature in the Arctic has increased by nearly four times the global average. Temperature has a significant effect on fundamental life‐cycle events of flora and fauna. With temperatures increasing, Arctic plants are expected to shift their active periods accordingly, with

Will landscape responses reduce glacier sensitivity to climate change in High Mountain Asia? [PDF]

The Cryosphere
In High Mountain Asia (HMA), ongoing climate change threatens mountain water resources as glaciers melt, and the resulting changes in runoff and water availability are likely to have considerable negative impacts on ecological and human systems. Numerous
