Fig. 1. Changes in dry mass (expressed as a percentage of the fed control; open squares) and percentage water content (filled triangles) during long-term fasting and subsequent refeeding in (A) the subterranean crustacean Stenasellus virei and (B) the surface-dwelling crustacean Asellus aquaticus at 11°C, in darkness. Values are means ± S.E.M. for N=10 animals. *Value significantly different from fed control (at time 0) (P<0.05).

Fig. 2. Changes in the levels of metabolites during long-term fasting (180 days) and subsequent refeeding (15 days) in the subterranean crustacean Stenasellus virei at 11°C, in darkness. Values are means ± S.E.M. for N=10 animals. *Value significantly different from fed control (at time 0) (P<0.05). dm, dry mass; fm, fresh mass. NEFA, non-esterified fatty acids.

Fig. 3. Changes in the levels of metabolites during long-term fasting (28 days) and subsequent refeeding (7 days) in the surface-dwelling crustacean Asellus aquaticus at 11 °C, in darkness. Values are means ± S.E.M. for N=10 animals. *Value significantly different from fed control (at time 0) (P<0.05). dm, dry mass; fm, fresh mass. NEFA, non-esterified fatty acids.
