[New publication] Mothers matter for the CO2 sensitivity of fish offspring

Posted on by

28 November 2017. The Journal of Experimental Marine Biology and Ecology just published the latest study by our group looking at differences in the CO2 sensitivity of Atlantic silverside offspring stemming from different mothers. Congratulations to Jacob Snyder for his first peer-reviewed publication.

Among the highlights of the study:

  • Offspring produced by different females varied in their sensitivity to high CO2 conditions.
  • Specific fatty acids in eggs were correlated to the log-transformed CO2 response ratio of embryo survival and hatch length.
  • Maternal provisioning might be an additional determinant of CO2 sensitivity in fish early life stages.

M. menidia. Responses to high CO2 conditions among replicates within and among females: (A) embryo and larval survival; (B) overall survival; (C) SL at hatch; and (D) final SL (16 dph). Patterns of larval growth were nearly identical to panel D and are therefore omitted. Ambient and high CO2 treatments are denoted by red and blue colors, respectively. Small symbols depict replicate survival (A,B) or replicate average size (C,D), while large symbols depict CO2 treatment averages for each female. Black lines connect average response for each female. Asterisks represent significant differences (P < 0.05) between CO2 levels within offspring of each female (Bonferroni adjusted t-test). Letters denote to females A to E.
