Snowmelt manipulation using shade cloths
Shade cloths suspended 3m above treatment plots accelerate snowmelt by 5-7 days when snowpack reaches ~1m depth, simulating earlier spring snowmelt conditions. Cloths removed after complete treatment ...
Split-plot snowmelt and precipitation manipulation experiment
A factorial field experiment manipulating snowmelt timing using black shade cloth and summer precipitation using rainout shelters in a split-plot design to simulate climate change effects.
Helianthella flower removal experiment (Asteraceae)
Experimental removal of flower buds to simulate frost damage effects, allowing comparison of microclimate conditions between plots with and without flower displays in subalpine meadow.
Reciprocal egg-transfer experiment for bee larval survival (Megachilidae)
Laboratory experiment transferring bee eggs between different pollen provision types to test effects on larval survival. Eggs moved between Taraxacum and native Asteraceae provisions in a balanced rec...
Factorial phenology-water manipulation of potted wildflowers
A factorial experiment manipulating both flowering phenology (by moving plants between elevations) and water availability (through differential watering regimes) using potted native plants in field ar...
Controlled frost sensitivity chamber experiment (Plantae)
Plant tissues are subjected to controlled freezing temperatures in a programmable chamber to determine frost damage thresholds. Temperatures are gradually reduced to simulate natural frost events, the...
