Description

This dataset was used for the paper "Simulated riparian forest gaps and increased sediment loads modify stream metabolic patterns and biofilm composition". Raw data includes mesocosm stream channel oxygen data, temperature data, and flourometric chl a data. This manuscript is part of a larger project which aims at evaluating how current forest management practices effect ecological functions of headwaters. This specific dataset was collected to answer how fine sediments and light conditions affect algal biofilms in small, boreal waters.

Data collection

Data collection 1

  • Mode of collection: Experiment
  • Description of the mode of collection: We estimated biofilm biomass as chl α (µg cm-2) in each channel. For all chl α estimates, we used a BenthoTorch, an in-situ, hand-held fluorometric instrument (bbe Moldaenke, Germany). The BenthoTorch estimates chl α and distinguishes between diatoms, green algae and cyanobacteria. Estimates of total chl α from a BenthoTorch compare well with conventional spectrophotometric methods when biofilms are relatively thin, as in our situation. However when quantifying community composition, the BenthoTorch have been shown to overestimate the abundance of diatoms, yet the instrument performs well in factory calibrations against standards. Still, we only used the community composition results to note presence or absence of green algae in the channels. All statistical analyses used the sum of diatoms, green algae and cyanobacteria (i.e. total chl α).
  • Time period(s) for data collection: 2022-07-01 – 2022-10-31
  • Instrument: BenthoTorch (Technical instrument(s)) - Handheld, in situ fluorometric chla analyser
  • Temporal resolution: 7 day

Data collection 2

  • Mode of collection: Experiment
  • Description of the mode of collection: Each channel was equipped with a miniDOT (Precision Measurement Engineering Inc., USA) to record dissolved oxygen. Metabolism was estimated using the single-station diel oxygen method approach where gross primary production (GPP) and Ecosystem Respiration (ER) was estimated using Bayesian inverse modelling.
  • Time period(s) for data collection: 2022-07-01 – 2022-10-31
  • Instrument: miniDOT (Technical instrument(s)) - A miniDOT records dissolved oxygen and is deployed in water
  • Temporal resolution: 10 minute
Geographic coverage
