What is Trade-offs in the life history and energy budget of the parthenogenetic collembolan Folsomia candida (Willem) about?

Three clones of Folsomia candida from different locations in Europe were compared in four experiments investigating genetic and phenotypic correlations between life-history traits. The first three experiments focused on the effects of food type, clone and temperature on traits associated with the first clutch. Differences in clutch size between clones and treatments were almost completely attributable to body size. Clones differed in length of the juvenile period, but the difference decreased at low temperatures. Age and weight at first reproduction were negatively correlated in the food type experiment and positively correlated in the temperature experiment, an often-encountered result for which no general explanation is as yet available. In the temperature experiment egg size variation was considerable, and was highest at low temperatures. The fourth experiment, with two clones at two feeding levels, aimed at finding trade-offs, in particular between reproduction and survival. It was hypothesized that higher fecundity led to increased scenescence through a higher metabolic rate. The trade-off was clearly present among the clones: one combined fast growth, late reproduction and hi
