Impact of warming on Nostoc colonies (Cyanobacteria) in a wet hummock meadow, Spitsbergen

Original language description

In order to simulate the warming effects on Arctic wetlands, three passive open-top chambers (OTCs) and three control cage-like structures (CCSs) equipped with soil temperature and soil volumetric water content (VWC) probes for continuous microclimatic measurements were installed in a wet hummock meadow, Petuniabukta, Billefjorden, central Spitsbergen, in 2009. The warming effects on primary productivity were investigated during summer seasons 2009 and 2010 in cyanobacterial colonies of Nostoccommune s.l., which plays an important role in the local carbon and nitrogen cycles. The microclimatic data indicated that the effect of OTCs was dependent on microtopography. During winter, two short-term snow-thaw episodes occurred, so that liquid water was available for the Nostoc communities. Because of the warming, the OTC hummock bases remained unfrozen three weeks longer in comparison to the CCSs and, in spring, the OTC hummock tops and bases exceeded 0 deg.C several days earlier than CCS o
