Controlled experiment manipulating predator presence by establishing artificial aphid colonies, protecting them from natural predators, then adding lygus bugs to treatment plants. Includes ant bridge ...

Experimental manipulation using physical barriers to exclude ants from aphid colonies while maintaining control colonies with ant access. Uses paired treatment design on same plants to test effects of...

A controlled field experiment testing the effects of nitrogen addition and reduction on plant community composition over 8 years. Annual percent cover monitoring tracked responses of invasive and nati...

Flowers are bagged to prevent natural parasitism, then exposed to controlled introductions of parasitoid wasps or ambient parasitoid activity, followed by assessment of parasitism effects on seed pred...

A two-phase field protocol using training baits scented with plant chemicals followed by two-choice tests to assess whether ants form associative memories linking plant odors to carbohydrate rewards. ...

Experimental advancement of snow melt timing using shade cloth application to test effects on host plant phenology and aphid-plant interactions. Combined with temperature manipulation using open-top w...
