Plant's-eye view of temperature governs elevational distributions

Popis výsledku v původním jazyce

Explaining species geographic distributions by macroclimate variables is the most common approach for getting mechanistic insights into large-scale diversity patterns and range shifts. However, species&apos; traits influencing biophysical processes can produce a large decoupling from ambient air temperature, which can seriously undermine biogeographical inference. We combined stable oxygen isotope theory with a trait-based approach to assess leaf temperature during carbon assimilation (T-L) and its departure (Delta T) from daytime free air temperature during the growing season (T-gs) for 158 plant species occurring from 3,400 to 6,150 m a.s.l. in Western Himalayas. We uncovered a general extent of temperature decoupling in the region. The interspecific variation in Delta T was best explained by the combination of plant height and delta(13) C, and leaf dry matter content partly captured the variation in T-L. The combination of T-L and Delta T, with Delta T contributing most, explained the interspecific difference in elevational distributions. Stable oxygen isotope theory appears promising for investigating how plants perceive temperatures, a pivotal information to species biogeographic distributions.
