We examined ontogenetic variation in biomass allocation in Himalayan forb Potentilla pamirica across its 5,250–5,900-m elevation range. Our analyses rejected ontogenetically fixed allometry and instead found high variation in biomass allocation depending on age, size and environment, supporting optimal partitioning theory. The uneven allocation of resources to different structures and functions during ontogenesis reflects plant adaptations to different levels of low-temperature and water stress across species elevation range.
