Aggregation of isopod species differing in desiccation resistance at different temperatures. Mean ± 1 SE aggregation indices (variance:mean ratio) at 90% relative humidity. a P. scaber (F 4,249 = 3.76, p < 0.01) b A. vulgare (F 4,249 = 1.97, P < 0.01) c O. asellus (F 4, 249 = 12.22, P < 0.001) d thermal reaction norms for aggregation expressed as quadratic response curves for: P. scaber (dashed line): y = -11.519 + 1.526× - 0.04×2; A. vulgare (solid line): y = -3.534 + 0.574× 0.016×2; O. asellus (dotted line): y = -5.890 + 0.814× – 0.018×2.
