Subtle direct effects of rising atmospheric <scp>CO 2 </scp> on insect eggs
Abstract Ocean acidification is an important consequence of rising levels of atmospheric CO 2 . The chemistry of acidification is, however, general and may disturb pH in terrestrial systems.

Abstract Ocean acidification is an important consequence of rising levels of atmospheric CO 2 . The chemistry of acidification is, however, general and may disturb pH in terrestrial systems.

Newly‐laid eggs of the moth Manduca sexta are exposed to levels of CO 2 between 0 and 2200 p.p.m., in air, and effects on yolk pH , total developmental time, and survival are measured.
