Coleoptera associated with intermittent streams and their riparian zones in south coastal British Columbia

Abstract Intermittent streams that periodically cease surface flow have long been understudied in ecology and underrepresented conservation policy. However, they currently account for 30–50% of the global river network, number is rising due to anthropogenic water extraction, land-use change, climate change. We explored Coleoptera biodiversity south Pacific coast region British Columbia, Canada, using pitfall traps at perennial naturally intermittent stream reaches, shoreline, dry streambed, riparian habitats, both flowing (spring early summer) nonflowing (late phases. found habitats around reaches had significantly greater abundance individuals than did those reaches. neither habitat type nor regime was a significant predictor taxon richness, sites featured unique taxa were not near streams. This aligns with recent results from other taxonomic groups; is, finding ecosystems can host high diversity Coleoptera, on par or even Because will likely become more prevalent within better understanding how different species use these needed inform appropriate efforts management.
