I don't see much literature on this topic, but the Great Lakes and Lake Michigan, in particular, have experienced rapid change in water levels over the past decade. Have these changes facilitated invasion? I don't see much literature out there on this topic. This attached paper eludes to NNIP facilitation, though.
Interesting to know about that. I expect such research from lakes made by damming rivers for hydropower as their levels keep fluctuating regularly. In fact I had suggested this research to one of our botany professors in late 1970s but was slapped with a wry smile. Keep it up brother, you are likely to put some new light in this direction.
Fluctuating water levels can facilitate the spread of non-native aquatic invasive species in the Great Lakes by providing opportunities for these species to move between connected water bodies. For example, if water levels are low, non-native species may be able to cross land barriers such as roads or railways that were previously underwater. Similarly, if water levels are high, non-native species may be able to spread through channels or other water connections that were previously not accessible.
Additionally, fluctuating water levels can also impact the survival and reproduction of non-native species in the Great Lakes. For example, high water levels may provide suitable habitat and cover for non-native species, while low water levels may expose these species to increased predation or other environmental stresses.
Overall, the potential impacts of fluctuating water levels on the spread and survival of non-native aquatic invasive species in the Great Lakes highlights the importance of water level management and the need for efforts to prevent the introduction and spread of these species.
