Our findings are consistent with prior studies that have inferred multiple origins of ECM, with no reversals [ 1, 2, 5] and they clearly reject the view that the common ancestor of all Agaricomycetes was mycorrhizal, with saprotrophy being a generally derived condition [ 11].
Some poetry: 1969 Reversals; '74 Correspondences; '87 Selected Poems; '96 Collected Poems 1955-1995; 2000 Granny Scarecrow; '03 A Report from the Border.
The excellent four-member cast, led by Debra Monk and directed by Peter Askin, finds charm and energy amid the vaporous bait-and-switch plot reversals (2 00).
The number of dots and rotation velocity were chosen to maximize the number of reversals [23].
GLR-1 mediates spontaneous reversals in locomotion during foraging, and glr-1 mutants have a reduced frequency of spontaneous reversals [10], [21], [32].
These commonly occur after a reversal and facilitate a change in direction and only rarely occur independently of reversals [37].
SNP characters are rare in the B. anthracis genome and almost never have character state reversals (∼0.1% homoplasy) [14].
Inversely, none of these sequences of reversals is equivalent to {1}{2,3,4}{1,2,3} because the reversals {1,2,3} and {2,3,4} overlap.
A series of three reversals was given, whereby in each reversal the previously correct lever became incorrect and the previously incorrect lever became correct (reversals 1 3).
Reversal data were subjected to a repeated measures ANOVA where the between-subjects factor was lesion group and the within-subjects factor the phase (serial reversals: three levels, reversals 1 3; retention of reversals: three levels, retention reversals 1 3) or the type of error (two levels: perseverative and learning).
