Life history theory predicts that plants in adverse environments for juvenile performance start reproduction at a smaller size and exhibit higher reproductive allocation compared to their counterparts in more favourable environments. Merinero et al. explore the reproductive strategy of an asexually reproducing lichen along a rainfall gradient.
Consistent with the predictions of life-history theory, they find a decrease in the size for reproduction, and a higher reproductive allocation in drier, adverse, environments. By focusing on an asexually reproducing lichen, the study improves our understanding of life history diversity and reproductive strategies across environments.
