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...

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...

Artificial stream channels with controlled flow regimes and nutrient treatments to test effects of phosphorus availability on D. geminata growth and bloom formation.

Controlled experiment using flow-through tanks to test whether artificial D. geminata mats (polyester pillow stuffing) provide refuge for T. tubifex from stonefly predation. Treatments included presen...

Manual removal of invasive diatom D. geminata from stream substrate plots with adjacent controls to test effects on invertebrate community composition and abundance over a three-week period.

Experimental manipulation of existing egg mass densities on preferred substrates to test whether females exhibit aggregative oviposition behavior in response to conspecific egg presence.

Experimental removal of D. geminata cells and stalks from stream rocks to test regrowth capacity under natural conditions with different initial stalk densities.
