Distribution and diversity of Tardigrada along altitudinal gradients in the Hornsund, Spitsbergen (Arctic)
Two transects were established and sampled along altitudinal gradients on the slopes of Ariekammen (77°01′N; 15°31′E) and Rotjesfjellet (77°00′N; 15°22′E) in Hornsund, Spitsbergen. In total 59 moss, lichen, liverwort and mixed moss–lichen samples were collected and 33 tardigrade species of Hetero- a...
