Thermal reaction norm gradients for evaporation rate (water loss) for isopods from biomes differing in availability of moisture. Evaporation rate (g g-1 h-1× 10-2) standardised to a temperature range of 3.5 °C (from Edney 1951; Warburg 1965, 1987, 1989). Key to species: Lo Ligia oceanica, Ph Philoscia muscorum, Oa Oniscus asellus, Ps Porcellio scaber, Av Armadillidium vulgare, Ao Armadillo officinalis, Aa Armadillo albomarginatus, Po Porcellio olivieri, An Armadillium nasatum, Ba Buddelundia albinogrisescens, Bf Buddelundia frontosa, Va Veneziillo arizonicus, Bsp Buddelundia spp. probably lateralis, Hr Hemilepistus reaumurii, Sf Schizidium festai. Key to habitats: littoral (blue), mesic (green), xeric (yellow), semi-arid (orange) habitats in South Australia.
