Osmoxylon‐like fossils from early Eocene South America: West Gondwana–Malesia connections in Araliaceae

American Journal of Botany, EarlyView.
Abstract Premise Araliaceae comprise a moderately diverse, predominantly tropical angiosperm family with a limited fossil record. Gondwanan history of Araliaceae is hypothesized in the literature, but no fossils have previously been reported from the former supercontinent.

Dyslipidemia and the preventive potential in the Greenlandic population

Atherosclerosis Plus, 2023
Background: Low-density lipoprotein cholesterol (LDL-C) is a well-established risk factor for development of cardiovascular diseases. Based on available clinical data, we aimed to investigate the plasma lipid profile in the Greenlandic population, the ...

Using local ecological knowledge as evidence to guide management: A community‐led harvest calculator for muskoxen in Greenland

Conservation Science and Practice, 2020
Indigenous people manage or have tenure rights on over a quarter of the world's land surface. While there is growing interest in “evidence‐based” natural resource management, there are few documented experiences with “evidence‐based” practice in ...

The Chernobyl Reference Horizon (?) in the Greenland Ice Sheet [PDF]

, 1989
Published reports of the presence of radioactive debris from the Chernobyl reactor accident in snow on the Greenland ice sheet raised the strong prospect that such debris might constitute a valuable time stratigraphic marker all over the ice sheet. Large

Phylogenetic relationships and the identification of allopolyploidy in circumpolar Silene sect. Physolychnis

American Journal of Botany, EarlyView.
Abstract Premise Species complexes are groups of closely related species with ambiguous delimitation, often composed of recently diverged lineages. Polyploidization and uniparental reproduction (i.e., selfing and apomixis) can play important roles in the origin of species complexes. These complexes pose challenges for species‐based scientific questions,

High export of dissolved silica from the Greenland Ice Sheet

Geophysical Research Letters, 2016
Silica is an essential element for marine life and plays a key role in the biogeochemistry of the ocean. Glacial activity stimulates rock weathering, generating dissolved silica that is exported to coastal areas along with meltwater. The magnitude of the

Paleocene-Eocene volcanic segmentation of the Norwegian-Greenland seaway reorganized high-latitude ocean circulation

Communications Earth & Environment, 2021
Uplift and volcanism drove fragmentation of the Norwegian-Greenland seaway, which may have restricted Arctic-Atlantic exchange during the Paleocene-Eocene Thermal Maximum, according to sedimentological, paleontological and seismic analyses from NE ...

Anatomy of a Dansgaard-Oeschger warming transition: High-resolution analysis of the North Greenland Ice Core Project ice core [PDF]

, 2008
Large and abrupt temperature oscillations during the last glacial period, known as Dansgaard‐Oeschger (DO) events, are clearly observed in the Greenland ice core record.
