Table 2 Mean (SD) of parameters measured or calculated on webs built by the spiders reared in frames

From: Does building activity influence web construction and web characteristics in the orb-web spider Zygiella x-notata (Araneae, Araneidae)?

Parameters Mean (SD) t test ( p)
Test 1 Test 2
Length of the spiral thread (cm) 492 (40) 358 (32) 5.05 (<0.001)
Surface of the capture area (cm2) 132 (12) 86 (12) 6.58 (<0.001)
Asymmetry 0.29 (0.02) 0.19 (0.02) 3.30 (0.004)
Number of radii 25 (1) 22 (1) 3.29 (0.004)
Length of the lower part (cm) 8.4 (0.5) 5.7 (0.4) 6.24 (<0.001)
Number of spiral turns 30 (2) 25 (2) 2.08 (0.049)
Mesh height (mm) 2.6 (0.1) 2.3 (0.2) 1.43 (0.165)
Anomaly ratio (A/CTL) 8 (0) 12 (1) 3.39 (0.002)
  1. Comparisons were made between tests 1 and 2 (t test for paired data, n = 25). Italicised characters indicate that the difference is significant at least at p < 0.05.
