Knowledge graph centered on D-frame net benthic sampling (Baetidae) with 12 nodes and 27 connections. Top connected: interspecific competition, foraging ecology, time allocation tradeoff, Microcosm predator avoidance bioassay, plant-pathogen interactions.
Description
Random collection of mayfly larvae from stream benthos using standardized D-frame nets, followed by preservation and microscopic examination for internal parasites. Used to compare parasite prevalence between metal-polluted and reference streams.
Typical Equipment
- D-frame net with 500μm mesh
- 70% ethanol
Output Measurements
- parasite prevalence
- mayfly abundance
