Corticosterone manipulation reveals differences in hierarchical organization of multidimensional reproductive trade-offs in r-strategist and K-strategist females

Abstract

Life history trade‐offs are often hierarchical with decisions at one level affecting lower level trade‐offs. We investigated trade‐off structure in female side‐blotched lizards (Uta stansburiana), which exhibit two evolved strategies: yellow‐throated females are K‐strategists and orange‐throated are r‐strategists. Corticosterone treatment was predicted to differentially organize these females’ reproductive decisions. Corticosterone‐treated yellow females suppressed reproduction but survived well, and augmented egg mass without decreasing clutch size. Conversely, corticosterone enhanced mortality and reproductive rates in orange females, and increased egg mass only after lengthy exposure. Corticosterone did not affect post‐laying condition, suggesting that corticosterone increased egg mass through enhanced energy acquisition (income breeding). Corticosterone enhanced survival of lightweight females, but decreased survival of heavy females, introducing a foraging vs. predation trade‐off. We conclude that rather than being a direct, functional relationship, observed trade‐offs between offspring size and number represent evolved differences in hierarchical organization of multidimensional trade‐offs, particularly in response to stress.

  • In side-blotched lizards, corticosterone suppresses reproduction in females with a slow life-history phenotype but increases reproductive rate in females with a fast life-history phenotype.

    “This kind of strategy-specific effect has been recently documented in side-blotched lizards: administration of corticosterone (the analogue of cortisol) suppresses reproduction in females with a slow LH phenotype, but increases the reproductive rate of females with a fast LH phenotype (Lancaster et al., 2007).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
