Arbuscular mycorrhizae on Axel Heiberg Island (80°N) and at Saskatoon (52°N) Canada
Arbuscular mycorrhizae (AM) are seldom reported from high latitudes. We found that Asteraceae ( Arnica , Erigeron , and Taraxacum ) at a site on Axel Heiberg Island (approximately 80°N) have abundant AM and fine endophytes (FE). We used standard microscopic methods for examination and quantification...
