Microcosm predator avoidance bioassay
Controlled experimental system using circular plastic tanks to test mayfly larval responses to chemical cues by measuring foraging behavior on substrate surfaces before and after treatment application...
Nutrient Diffusing Substrates (NDS)
Factorial experimental design using artificial stream channels to test temperature and nutrient effects on algae growth. Solar heating systems create temperature gradients while drip systems deliver c...
Flow-through channel mesocosm experiment
Artificial stream channels with controlled flow regimes and nutrient treatments to test effects of phosphorus availability on D. geminata growth and bloom formation.
Egg mass density manipulation experiment (Baetidae)
Experimental manipulation of existing egg mass densities on preferred substrates to test whether females exhibit aggregative oviposition behavior in response to conspecific egg presence.
In situ Didymosphenia regrowth manipulation
Experimental removal of D. geminata cells and stalks from stream rocks to test regrowth capacity under natural conditions with different initial stalk densities.
