Interactive effects of drought and shading on boreal stream metabolism and algal biomass in experimental mesocosms

https://doi.org/10.5878/fk59-8024
This dataset was collected and used in the article "Interactive effects of drought and shading on boreal stream metabolism and algal biomass in experimental mesocosms." The data include benthic chl-a and modeled oxygen data from experimental channels at the Svartberget Research Station, all of which have been modeled to calculate gross primary production and respiration. This manuscript is part of a larger project aimed at evaluating how modern forestry practices affect ecological functions in headwaters (small streams). This specific dataset was collected to investigate whether negative effects of clear-cutting on streams, such as altered light conditions, interact with extreme weather events such as drought.

Data collection Experiment

Mode of collection:

Experiment

Description of the mode of collection:

Full methods description in the file "Methods". In short, oxygen concentration was measured on the bottom of experimental channels in Svartberget research station using miniDOT loggers (Precision Measurement Engineering Inc., USA). Oxygen data was recorded at 10 minute intervals and later modelled to gross primary production and ecosystem respiration. The experimental channels were subjected to different treatments in light and drought. Each channel was measured 10 times per week for two months.

Instrument

Name:

miniDOT

Description of the instrument:

The miniDOT Logger from Precision Measurement Engineering Inc. is a fully submersible device designed to measure dissolved oxygen and temperature in aquatic environments. It utilizes an optical sensor (optode) that employs fluorescence quenching to determine oxygen concentrations, and records data onto an internal microSD card.

Experiment

Description of the mode of collection:

Full methods description in the file "Methods". In short, chlorophyll-a was measured on the bottom of experimental channels in Svartberget research station using a BenthoTorch (Moldanke BBE). The experimental channels were subjected to different treatments in light and drought. Each channel was measured 10 times per week for two months.

Instrument

Name:

BentoTorch

Description of the instrument:

The BenthoTorch is a handheld instrument that analyses chl-α pigments in-situ by fluorescence. The BenthoTorch measures an area of 1.1 cm2 and we systematically measured each channel once per week using established transects from top to bottom with ten measurements per channel and sampling occasion. The BenthoTorch enables frequent and non-destructive estimates of chl-α, which we could not accomplish using ceramic tiles or other sub-sampling of the channel bottom.
