Table 2 Correlation between bromeliad mosquito assemblage and environmental variables.

From: Mosquito (Diptera: Culicidae) assemblages associated with Nidularium and Vriesea bromeliads in Serra do Mar, Atlantic Forest, Brazil

Environmental variable Type of variable Redundancy analysis
Mean temperature Numeric, from 16.9 to 27.5°C Pseudo-F = 0.69, d.f. = 106 (p = 0.63)
Total precipitation Numeric, from 0.9 to 155.3 mm Pseudo-F = 0.13, d.f. = 106 (p = 0.99)
Bromeliad height Numeric, from 0 to 260 cm Pseudo-F = 0.61, d.f. = 106 (p = 0.68)
Type of bromeliad Factor, 3 levels (ground, epiphytic, rocky) Pseudo-F = 1.49, d.f. = 106 (p = 0.13)
Water pH Numeric, from 3.9 to 7.5 Pseudo-F = 0.41, d.f. = 106 (p = 0.86)

Tank depth Numeric, from 10 to 140 cm Pseudo-F = 0.98, d.f. = 106 (p = 0.41)
Landscape categories Factor, 3 levels (lowland, hillslope, hillside) Pseudo-F = 1.89, d.f. = 106 (p = 0.04)a
Bromeliad water volume Numeric, from 7 to 750 ml Pseudo-F = 2.99, d.f. = 106 (p = 0.03)a
Bromeliad fullness (water divided by depth) Numeric, from 0.2 to 17.5 ml/cm Pseudo-F = 4.47, d.f. = 106 (p < 0.01)a
  1. Results of the multivariate Redundancy analysis (RDA) showing correlations between bromeliad mosquito assemblage structure and environmental variables.
  2. a = Significant result under the null hypothesis: Pseudo-F = 0 (p < 0.05).
