Changes in invertebrate assemblage composition in benthic and hyporheic zones during a severe supraseasonal drought

  title={Changes in invertebrate assemblage composition in benthic and hyporheic zones during a severe supraseasonal drought},
  author={Rachel Stubbington and Andrew J. Boulton and Sally A. Little and Paul J. Wood},
Droughts are unpredictable disturbances characterized in streams by declining flow, reduced habitat availability, and deteriorating abiotic conditions. Such events typically reduce benthic invertebrate taxon richness and modify assemblage composition, but little is known about how hyporheic invertebrate assemblages respond to drought or how these responses relate to changes in benthic assemblages. We hypothesized that taxon richness (α diversity) and variability (as within-site β diversity) in… CONTINUE READING
