Contrasting Soil Thermal Regimes in the Forest‐Tundra Transition Near Nadym, West Siberia, Russia
G. V. Matyshak,O. Yu. Goncharova,Nataliya G Moskalenko,Donald A. Walker,Howard E. Epstein,Yuri Shur +5 more
TL;DR: In this paper, the effects of forest shading, snow cover and variable organic soil horizons in three common ecosystems of the forest-tundra transition zone were investigated, and the most informative annual parameters were: (1) the sum of positive average daily temperatures at depths of 10 and 20 cm; (2) the maximum penetration depth of temperatures above 10 cm; and (3) the number of days with temperatures below 0 cm at a depth of 20 cm.

Algal community response to experimental and interannual variation in hydrology in an Alaskan boreal fen
TL;DR: The differences in algal community structure among water-table treatments suggest that alternating drought and flooding events expected with climate change may significantly alter algal-driven functions in boreal wetlands.

Intercolony Variation in Growth of Black Brant Goslings on the
Yukon-Kuskokwim Delta,Thomas F. Fondell,Paul L. Flint,James S. Sedinger,Christopher A. Nicolai,Jason L. Schamber +5 more
TL;DR: This study studied gosling growth at 3 of the 4 major colonies on the YukonKuskokwim Delta, Alaska and found support for both explanations for the apparent growth rates.

Journal ArticleDOI
Increased plant growth in the northern high latitudes from 1981 to 1991
TL;DR: In this paper, the authors present evidence from satellite data that the photosynthetic activity of terrestrial vegetation increased from 1981 to 1991 in a manner that is suggestive of an increase in plant growth associated with a lengthening of the active growing season.

Characteristics of maximum-value composite images from temporal AVHRR data
TL;DR: In this paper, satellite data from the Advanced Very High Resolution Radiometer sensor have been processed over several days and combined to produce spatially continuous cloud-free imagery over large areas with sufficient temporal resolution to study green-vegetation dynamics.

Observational evidence of recent change in the northern high-latitude environment
Mark C. Serreze,John Walsh,F. S. Chapin,T. E. Osterkamp,Mark B. Dyurgerov,Vladimir E. Romanovsky,Walter C. Oechel,James H. Morison,Tingjun Zhang,Roger G. Barry +9 more
TL;DR: In this paper, the authors present asynthesis of these observations, and conclude that roughly half of the pronounced recent rise in Northern Hemispherewinter temperatures reflects shifts in atmosphericcirculation. But, such changes are not consistent with anthropogenic forcing and include generally positive phases of the North Atlantic and ArcticOscillations and extratropical responses to the El-NinoSouthern Oscillation.

Variations in northern vegetation activity inferred from satellite data of vegetation index during 1981 to 1999
Liming Zhou,Compton J. Tucker,Robert K. Kaufmann,Daniel Slayback,N.V. Shabanov,Ranga B. Myneni +5 more
TL;DR: In this paper, the authors present results from analyses of a recently developed satellite-sensed normalized difference vegetation index (NDVI) data set for the period July 1981 to December 1999, showing that about 61% of the total vegetated area between 40°N and 70°N in Eurasia shows a persistent increase in growing season NDVI over a broad contiguous swath of land from central Europe through Siberia to the Aldan plateau, where almost 58% (7.3×106 km2) is forests and woodlands.
