Another Winter Tundra [PDF]

open access: yesClinical Chemistry, 2017
Cold, windy, the house creaking, feeling the low temperature from the outside world. Freeze nipping at my bare toes. Barren trees, grey against the monochromatic sky, seemingly lifeless land, snow starts falling, swirling through the air, so soft and gentle. As I peek out the window, it turns to sleet.

Arctic shrubification mediates the impacts of warming climate on changes to tundra vegetation

open access: yesEnvironmental Research Letters, 2016
Climate change has been observed to expand distributions of woody plants in many areas of arctic and alpine environments—a phenomenon called shrubification.

The changing carbon balance of tundra ecosystems: results from a vertically-resolved peatland biosphere model

open access: yesEnvironmental Research Letters, 2021
An estimated 1700 Pg of carbon is frozen in the Arctic permafrost and the fate of this carbon is unclear because of the complex interaction of biophysical, ecological and biogeochemical processes that govern the Arctic carbon budget.

Origin, evolution and biogeographic dynamics of the European rabbit (Oryctolagus cuniculus) in Southwestern Europe

open access: yesThe Anatomical Record, EarlyView.
Abstract The Pleistocene is a key period for understanding the evolutionary history and palaeobiogeography of the European rabbit (Oryctolagus cuniculus). The species was first documented in southeastern Iberia at the beginning of the Middle Pleistocene and appears to have rapidly spread throughout Southwestern Europe, where it was found in numerous ...

Comparative patterns of winter habitat use by muskoxen and caribou in northern Alaska [PDF]

open access: yes, 1992
Thesis (M.S.) University of Alaska Fairbanks, 1992Snow depth and hardness strongly influenced selection of feeding zones, (i.e., those areas used for foraging), in late winter by both muskoxen (Ovibos moschatus) and caribou (Rangifer tarandus grand) in ...

Spatial patterns of goose grubbing suggest elevated grubbing in dry habitats linked to early snowmelt [PDF]

open access: yesPolar Research, 2013
The western Palaearctic tundra is a breeding habitat for large populations of European geese. After their arrival in spring, pink-footed geese (Anser brachyrhynchus) forage extensively on below-ground plant parts, using a feeding technique called ...

Ecological connection between fish preference in the diet of Siberian cranes and their incubation period in tundra zone [PDF]

open access: yes, 2012
We researched the ecology of the third rarest crane species, Siberian crane, which breeds in northern-eastern Siberian tundra. Nesting in places near great lakes, this crane appears to be an indicator of the global warming processes that affect lake ...

A review of the historic and present ecological role of aquatic and shoreline wood, from forest to deep sea

open access: yesBiological Reviews, EarlyView.
ABSTRACT The ecology of forests, their losses, and terrestrial wood decomposition dynamics have been intensively studied and reviewed. In the aquatic realm, reviews have concentrated on large wood (LW) in rivers and the transition from freshwater to marine environments in the Pacific Northwest of North America. However, a comprehensive global synthesis

Инициальное почвообразование в Прибрежной Антарктике: существуют ли не орнитогенные почвы?

open access: yesУкраїнський антарктичний журнал, 2017
Примитивные тундровые почвы сформировались и функционируют в суровых климатиче­ских условиях. Их изучение позволяет количественно оценить инициальные стадии почвообразова­ния, что крайне важно как для понимания процесса в целом, так и для создания ...

Fire-induced changes in soil and vegetation in the forest-tundra of Western Siberia [PDF]

open access: yesE3S Web of Conferences, 2020
Wildfires are one of the main factors for landscape change in tundra ecosystems. In the absence of external mechanical impacts, tundra plant communities are relatively stable, even in the face of climatic changes.
