Temporal variability of macroinvertebrate communities

Project background

This research was undertaken between 2006 and 2010 as part of a PhD by postgraduate student Rob Holland, who was based jointly in the Catchment Science Centre and the Department of Animal and Plant Science.

Long term data collected as part of the Environment Agency´s routine water monitoring programme, and historic data collected in Sheffield were used to address the following broad questions:

What are the spatial patterns in the temporal variability of macroinvertebrate communities in rivers?

What are the underlying reasons for any observed patterns?

Key findings

  • Temporal variability has a complex pattern across multiple spatial scales.
  • Climate, local land use, and local scale habitat stability are important determinants of variability in macroinvertebrate communities.
  • Community composition is related to temporal variability and certain taxa have a disproportionate effect on community variability.
  • Improvements in river quality over the last 30 years have resulted in considerable variation in the taxa present in macroinvertebrate communities over time.

Although part of this project examined a national component, the part within the Don catchment was focused on variation in taxa present in macroinvertebrate communities over time within Sheffield city.
