Knowledge graph centered on Digital image analysis with 41 nodes and 114 connections. Top connected: elevational gradients, pollinator observation, The evolution of wing color in <i>Colias</i> butte, floral visitation rate, thermal performance.
Description
Comprehensive measurement of forewing length, wing melanism, and setal length from pinned butterfly specimens using digital micrometry, photography, and microscopy. Wing melanism quantified using standardized grey-level analysis of photographs.
Typical Equipment
- digital micrometer
- Canon Rebel XSi
- 100-mm macro lens
- copy-stand
- Wild M5 microscope
- ocular micrometer
- MatLab program
Output Measurements
- forewing length
- wing melanism grey-level
- setal length
