Panagrolaimus magnivulvatus Boström, 1995 in nest material, algae and soils from inland nunataks in western Dronning Maud Land, Antarctica
Panagrolaimus magnivulvatus Boström, 1995 is reported from habitats on inland nunataks in western Dronning Maud Land, continental Antarctica. This species was recorded in lithosols of three of the 11 nunataks (Marsteinen, Lorentzenpiggen and Valterkulten) sampled during the 1992-93 summer. In additi...
