Local Knowledge Graph (13 entities)

Knowledge graph centered on Stream reach electroshocking for invertebrate manipulation (Heptageniidae) with 13 nodes and 32 connections. Top connected: space use, Reach-scale Manipulations show invertebrate grazer, trophic cascade, benthic sampling, Microcosm predator avoidance bioassay.

Description

Large-scale manipulation technique using backpack electroshocker to reduce invertebrate densities across a 50-meter stream reach through induced drift, with daily treatments maintained for two weeks. This enables testing of grazer effects on primary producers at natural spatial scales.

Typical Equipment

• generator-powered backpack electroshocker
• circular 10-cm anode (Model 15-C, Smith-Root)
• 280-μm mesh blocknet

Output Measurements

• invertebrate density reduction
• community composition changes
