Here we assess the relative contribution of these processes in community-level body-size changes in tropical moth assemblages that moved uphill during a period of warming. Based on resurvey data for seven assemblages of geometrid moths (>8000 individuals) on Mt. Kinabalu, Borneo, in 1965 and 2007, we show significant wing-length reduction (mean shrinkage of 1.3% per species). Range shifts explain most size restructuring, due to uphill shifts of relatively small species, especially at high elevations. Overall, mean forewing length shrank by ca. 5%, much of which is accounted for by species range boundary shifts (3.9%), followed by within-boundary distribution changes (0.5%), and within-species size shrinkage (0.6%). We conclude that the effects of range shifting predominate, but considering species physiological responses is also important for understanding community size reorganization under climate warming. © 2019, The Author(s).[SDGs]SDG13community composition; moth; physiological response; range expansion; adult; article; body size; Borneo; climate warming; female; human; human experiment; major clinical study; male; moth; nonhuman; wing; altitude; anatomy and histology; animal; body size; Borneo; climate change; Malaysia; physiology; Borneo; East Malaysia; Malaysia; Mount Kinabalu; Sabah; Geometridae; Lepidoptera; Altitude; Animals; Body Size; Borneo; Climate Change; Malaysia; MothsReduced body sizes in climate-impacted Borneo moth assemblages are primarily explained by range shiftsjournal article10.1038/s41467-019-12655-yhttps://www.nature.com/articles/s41467-019-12655-y
