Fig 3. Distanced-based redundancy analyses (dbRDA) plots of species composition and the environmental variables for all streams.

Fig 3

The colors demonstrate the degree of urbanization (red), that is, when the point is red, it presents a high degree of urbanization. The arrows indicate how the variables are related to the dbRDA axes and the underlined variables were statistically significant. IDI- Integrated Disturbance Index, RHDA- Rapid Habitat Diversity Assessment, TDS- Total dissolved solids, TP- Total phosphorus, NH4- Ammonia, TPT- Temperature, CON- Conductivity, DO- Dissolved oxygen, TUR- turbidity.
