Patchy surface stone movement during disturbance in a New Zealand stream and its potential significance for the fauna
Article Abstract:
Patchy surface stone movement during disturbance in a New Zealand stream is discussed relative to its potential significance for fauna. Such patchy movement has been proposed based on field observations, but little in the way of quantification has been undertaken. Monitoring of stability of surface stones was undertaken at three geomorphically different sites in the river in three spates and one large flood. It may be possible to use small-scale experiments to simulate effects of disturbance on the benthic community more effectively than had been supposed.

Crevices as refugia for stream diatoms: effect of crevice size on abraded substrates
Article Abstract:
Crevices as refugia for stream diatoms are discussed relative to mechanisms and the effects of crevice size on abraded substrates. A study of four substrates with different crevice features showed crevices to be potentially important refugia from abrasive disturbances. Detritus built up in all crevices, accumulation increasing with level of abrasion.
