Description
Thaysa G Oliveira leads a 2026 study of how heat and immune stress together affect movement in female African clawed frogs. Cold-blooded animals face trade-offs, because fighting infection costs energy. Frogs were injected with a bacterial part that mimics infection, or with salt water. Their stamina and jump force were then measured in cold, ideal, and warm conditions.
Immune stress cut movement at every heat level. Stamina peaked near the ideal level and fell at both extremes, most sharply in the frogs that mimicked infection. Jump force losses were alike across all levels. Great heat or cold can deepen the costs of infection, the authors warn. That can limit escape, spread, and survival of whole groups.
