Multi-trophic level responses to marine heatwave disturbances in the 
California Current Ecosystem
By Tz-Chian Chen
Description: Marine heatwaves (MHWs) caused by multiple phenomena with 
days to months duration are increasingly common disturbances in ocean 
ecosystems. We investigated the impacts of MHWs on pelagic communities 
using spatially-resolved time-series of multiple trophic levels from the 
Southern California Current Ecosystem. Indices of phytoplankton biomass 
mostly declined during MHWs because of reduced nutrient supply 
(excepting Prochlorococcus) and were generally more sensitive to marine 
heatwave intensity than duration. By contrast, mesozooplankton (as 
estimated by zooplankton displacement volume) were somewhat more 
strongly correlated with MHW duration than intensity. Zooplankton 
anomalies were also positively correlated with fucoxanthin (diatom) 
anomalies, highlighting possible bottom-up influences during MHWs. 
Mobile consumers (forage fish) showed more complex responses, with fish 
egg abundance declining during MHWs but not correlating with any MHW 
characteristics. Our findings provide partial evidence of how MHW 
characteristics can shape variable ecological responses due to the 
differing life spans and behaviors of different trophic levels.
