Effect of elevated O3 associated with Bt cotton on the abundance, diversity and community structure of soil Collembola

▶ Bt cotton can buffer the effect of elevated O3 on soil collembolans through root-derived ways. ▶ Elevated O3 had an extensive adverse effect on Collembola, but the effect of the Bt crop on Collembola was species- specific. ▶ Euedaphic collembolans were more sensitive toelelvated O3 and Bt cotton cultivation.
