📌 Transects
A transect is a line across an area where conditions change (e.g., shore to inland):
- Line transect — record organisms touching the line
- Belt transect — use quadrats at regular intervals along the line
- Shows how distribution changes with environmental gradient
- Useful for studying zonation (e.g., on a rocky shore)
