Abstract: In this research, I reviewed prospects for discovery of new species, which are likely to be small, live in hard-to-access areas, or have small geographic ranges. I explored one hard-to-access-area, tropical rainforest canopy, and examined biodiversity patterns along two nested climate gradients: forest height within elevation. I proposed a novel ?arboreality hypothesis? based on empirical data to explain the vertical shift in species distributions in the rainforest strata with shifts with elevation, due to changes in climate up trees relative to up mountains. I explored how microhabitats, especially Asplenium bird?s nest ferns, within the forest strata ameliorate abiotic conditions and promote canopy biodiversity. I showed that ferns provide thermal buffering dependent on their state of hydration. Fourth, I determined the critical thermal maxima for various species of frogs and lizards, at different life stages, and then explored whether forest microhabitats are likely to provide refuge from extreme weather events.
