Nematode species were extracted from two species of bryophyte (Cephaloziella varians and Sanionia uncinata) in a vegetated gully on Rothera Point, Adelaide Island. Nematode species were extracted from 10 fixed plots: five control plots, and five warmed plots (covered with open top chambers for the duration of the experiment). Sampling occurred over eight days between 2007 and 2010. The total number of nematodes in each sample, along with the numbers of males, females and juveniles of each species, were recorded and expressed per gram dry weight of bryophyte colony. The numbers of gravid females of Plectus belgicae, along with the total number of eggs in gravid females, were also recorded at four of the samplings.
