The Effect of Synthetic Estrogen on Foraging and Predator Avoidance in the Common Roach (Rutilus rutilus)
Synthetic estrogens that originate mainly from oral contraceptive pills reach our waters through sewage effluent and potentially affect organisms in the natural environment. This study focused on the effects of the synthetic estrogen 17-alpha-ethinylestradiol (EE2) on the foraging and predator avoidance behaviors of the planktivorous fish roach (Rutilus rutilus), a common fish in Swedish lakes and
