PCA ordination. Shows the position of sampling dates (May 2007-March 2010) for (a) Nant y Fall and (c) Chiquito streams; and trait composition at (b) Nant y Fall and (d) Chiquito Streams (Patagonia, Argentina), for the same coordinates. Open circles correspond to pre-eruption sampling dates, and filled circles indicate post-eruption sampling dates. Codes for trait states are described in Table 4.
