Fig. 4

Functional chloroplast (cps) and lysosome abundance (lys) in E. cornigera and E. timida 25 °C. a-i E. cornigera. j-r E. timida. Functional chloroplasts are depicted by red squares, the dark red ones showing the average per specimen (n = 3) and the light red squares showing the average of these three specimens representing the species average at each time point. Lysosomes within the digestive gland tubules (DGT) are illustrated with blue circles, the dark circles again showing the specimen average and the light circles revealing the species average. Lysosomes outside the DGT are demonstrated by green triangles, the dark depicting the specimen average and the light green indicating the species averages. For clarity, error bars (standard error) are only shown for the species average. b E. cornigera cp abundance at 0-days starved. Cps are falsely colored red. c E. cornigera lys abundance at 0-days starved. Lys are falsely colored blue. d, e E. cornigera – 7-days starved. f, g E. cornigera – 14-days starved. h, i E. cornigera – 21-days starved. j Cp and lys abundance in E. timida starved at 25 °C. Functional cps and lys in/out DGT are depicted as described above for (a). k Cps in E. timida 25 °C starved for 0 days. l Lys in E. timida 25 °C starved for 0 days. m, n E. timida 25 °C – 14 days starved. O, p E. timida 25 °C – 21 days starved. q, r E. timida 25 °C – 42 days starved. Error bars are not depicted here for graph clarity and can be found in the text. Scale bar – 50 μm
