| Abstract: | Purpose Evidence has accumulated that humic substances (HS) are not inert biogeochemicals. Rather, they cause stress symptoms and
may modulate the life history of aquatic organisms. Nevertheless, it is still not clear how HS interact with additional stressors
and if their effects are transgenerational. We tested the interactive effects of HS and salt to cladocerans, discussing their
consequences for the persistence in fluctuating environments, such as coastal lagoons. |
