Method synopsis

Infrared heaters suspended above experimental plots to simulate warming effects on montane vegetation communities across moisture gradients. Heating power adjusted over time to maintain consistent warming effect.

Synthesized from method descriptions across 16 papers using this protocol.

Procedure from a recent peer-reviewed implementation

Steps below were extracted from the most recent peer-reviewed implementation of this protocol in the corpus — Convergent ecosystem responses to 23-year ambient and manipulated warming link advancing snowmelt and shrub encroachment to transient and long-term climate–soil carbon feedback (2015), Global Change Biology. The protocol was originally introduced by Control of litter decomposition in a subalpine meadow-sagebrush steppe ecotone under climate change (2001), Ecological Applications. Implementations in other papers (listed below) may differ.

1. Establish experimental plots
   Ten plots of 3m x 10m were established in a subalpine montane meadow. Five plots had overhead infrared radiators installed for warming treatment, five served as ambient controls.
   Quantities: 10 total plots: 5 heated, 5 ambient control; 3m x 10m plot sizeDuration: Established in 1989, maintained for 23 years through 2013Conditions: Subalpine meadow at 2920m elevation, relatively dry upper and middle zones, moist flat lower zone
   Equipment: overhead infrared radiators
2. Apply experimental warming
   Infrared radiators provided continuous heating throughout growing season, warming soil surface by 1-2°C and extending snow-free season by average of 2 weeks at each end. Heating was 10-20% on gravimetric basis during growing season.
   Quantities: 1-2°C soil surface warming, 10-20% heating on gravimetric basis, 2 week extension of snow-free seasonDuration: Continuous heating throughout growing seasons from 1989-2013Conditions: Year-round operation with adjustments for seasonal conditions
   Equipment: infrared radiators
