Artificial light pollution increases the sensitivity of tropical zooplankton to extreme warming

摘要: Abstract Artificial light pollution and climate change are two important threats to the coastal ecosystems worldwide. However, potential interaction of artificial extreme warming on species is unknown. To address this issue, we exposed a tropical copepod Pseudodiaptomus incisus one twelve combinations four photoperiods (0L:24D, 12L:12D, 18L:6D 24L:0D — light: dark cycle) three temperatures (26, 30 34 °C). We quantified five key productivity parameters, including development time, body size all 12 stages, clutch size, hatching success nauplii production. P. had larger higher production at photoperiod 12L:12D than in continuous lighting condition (24L:0D). Copepods developed faster but showed smaller 34 °C 26 °C. Importantly, resulted stronger reductions 34 °C. Our results suggest that may increase vulnerability zooplankton with ecological consequences.
