A glimpse into the future through color

Paramos are biodiversity hotspots responsible for several key ecosystem services. These tropical high-mountain ecosystems are being subject to different anthropogenic threats, which include climate change. Using Open Top Chambers (OTC) to increase temperature in situ we are simulating future warming in the paramo Matarredonda on the eastern range of the Andes. Additionally, through hyperspectral imaging (HSI) and the use of vegetation indexes, we evaluated the physiological status of two paramo species, E. argentea and E. grandiflora, and the effect of warming on these indexes. Our results indicate that the physiological status of both species is changing due to an increase in temperature, where plants have less chlorophyll content, water content and suggest lower nitrogen uptake, among other stress indicators. Our results indicate that HSI can be used in the conservation of paramo plants for rapid evaluations of their status
