Finn, D.S.; Johnson, S.L.; Gerth, W.J.; Arismendi, I.; Li, J.L. 2022. Spatiotemporal patterns of emergence phenology reveal complex species-specific responses to temperature in aquatic insects. Diversity and Distributions. 28(8): 1524-1541. doi:https://doi.org/10.1111/ddi.13472
Aim: Climate change is broadly affecting phenology, but species-specific phenological response to temperature is not well understood. In streams, insect emergence has important ecosystem-level consequences because emergent adults link aquatic and terrestrial food webs. We quantified emergence timing and duration (within-population synchronicity) of insects among streams along a spatiotemporal gradient of mean water temperature in a montane basin to assess the sensitivity of these phenological traits to heat accumulation from mid-winter through spring emergence periods.
