Knowledge graph centered on Concentric circle floral density estimation (Megachilidae) with 34 nodes and 104 connections. Top connected: phenological mismatch, climate change effects on species interactions, reproductive success, thermal performance, Direct benefits and indirect costs of warm tempera.
Description
Floral resource availability was quantified by counting flowers while walking in progressively larger circles from a central point until reaching 100 flowers or 100m radius. Density was calculated as 100/πr² where r is distance to 100th flower.
Typical Equipment
- measuring tape
- field notebooks
- plant identification guides
Output Measurements
- floral density (flowers/m²)
- floral resource availability
