Lonicera maackii is an invasive woody shrub currently present at high densities in many Midwestern successional forests. Lonicera maackii has been observed to inhabit a broad range of light environments and colonizes both high and low quality habitat. Previous research produced evidence of higher reproductive rates with increasing light. The results of current research, addressed in this work, demonstrate that although L. maackii has been touted to prefer a high-light environment, it is capable of acclimating to low light without a loss in photosynthetic rate. Lonicera maackii demonstrates higher aboveground biomass accumulation as the duration of light availability increases, demonstrating acclimation to overall light regime rather than higher light intensity. Despite physiological acclimation to high light, L. maackii employs a strategy of long-term light acquisition in full-sun, forest edges, and canopy gaps rather than higher photosynthetic rates. These findings show that reducing season-long light availability should inhibit rapid growth, biomass acclimation, and reproductive potential.
