From: Identifying community thresholds for lotic benthic diatoms in response to human disturbance
Structural equation modeling identifying significant pathways among human land use, natural environmental variables, in-stream stressors, and lotic benthic diatom species composition (χ2 = 0.350, RMSEA = 0.024, CFI = 0.993). Solid lines indicate positive standardized path coefficients (r), and dotted lines indicate negative ones. Thicker lines represent stronger relationships (—: |r| < 0.3; ─: 0.3 ≤ |r| < 0.5; ▬: |r| ≥ 0.5). For the full names of each variable, please see Table 1.
