Fig. 1From: Time budget, oxygen consumption and body mass responses to parasites in juvenile and adult wild rodentsPredicted and observed changes in the energy budget of flea-infested rodents. Predicted (a) and observed (b) changes in the energy budget of juvenile and adult rodents under natural infestation levels due to energy consumption of fleas and flea-induced behavioral changes (filled and empty triangles for adults and juveniles, respectively) and compensatory response by juvenile (empty arrows) and adult (filled arrows) hosts (reproduced from Munger & Karasov, [1]). All relevant components are considered, while only underlined components were directly tested during the study. Filled squares indicate the compensatory responses by adults supported, but not proven, by the resultsBack to article page
