BiologyIn order to survive in its harsh environment, Tiquilia nesiotica has evolved various strategies. Competition for water forces the individual plants to grow widely spaced apart, spreading their roots horizontally beneath the surface to maximise the uptake of any available moisture. Like many plants in arid regions, the small leaves and grey appearance of Tiquilia nesiotica are adaptations to reduce the amount of heat the plant receives, preventing damage to its photosynthetic tissue and reducing moisture loss (3). As one of the few plants able to colonise the barren volcanic slopes of the Galapagos, Tiquilia nesiotica plays an important ecological role, as its roots stabilise the loose, ashy soil (5), its flowers provide food for lava lizards, and its pollen and nectar are a source of nutrition for insects (2).
