title: Data from: Antibiotics disrupt bacteria-phytoplankton symbioses: Unveiling ecological risks in aquatic ecosystems

description: Antibiotic pollution in natural water bodies has reached alarming levels,
 posing a significant threat to the delicate balance of aquatic ecosystems.
 Bacteria and phytoplankton are foundational components of these
 ecosystems, playing crucial roles as decomposers and primary producers,
 respectively, and their symbiotic relationships are essential for
 maintaining ecological stability. Despite accumulating research focusing
 on the direct toxic effects of antibiotics, disruptions of complex
 bacteria-phytoplankton symbioses remain largely underexplored. In this
 review, we first introduce the symbiotic mechanisms between bacteria and
 phytoplankton, highlighting the processes underlying the formation of
 these relationships. We then examine the antibiotic sensitivity of
 bacteria and phytoplankton, highlighting the heightened vulnerability of
 bacteria. Finally, we explore the mechanism by which antibiotics disrupt
 bacteria, leading to altered interactions with phytoplankton. These
 disruptions cause shifts in phytoplankton population community structure
 and dynamics with implications for ecosystem functions, including a higher
 risk of exacerbation of harmful algal blooms. Our study reveals that even
 if environmental concentrations of antibiotics do not directly impact
 phytoplankton populations, they can affect phytoplankton populations and
 communities by altering symbiotic bacteria. Understanding
 bacteria-phytoplankton symbioses is thus essential for unraveling the
 ecological impacts of antibiotics. This underexplored field demands
 greater attention from pollution ecology researchers, as it is key to
 defining environmental thresholds for pollutants.
