"Nonindigenous" refers to species or organisms that are not native to a particular area or ecosystem. These species have been introduced by human activities and can have disruptive effects on the local environment and native species.

For the impact of this species and any other aquatic nonindigenous species in the Great Lakes, I recommend searching the Great Lakes Aquatic Nonindigenous Species Information System (GLANSIS). It's created by NOAA and has a lot of basic information, resources, and the distributions of nonindigenous species in the Great Lakes.In terms of freshwater jellyfish (C. sowerbii), there is, unfortunately, quite a lack in available information. There is a lot of speculation that they may impact zooplankton communities due to predation pressure on particular species and sizes. As a result, in some laboratory experiments, declines in zooplankton abundance and some changes in morphological features have been observed.In one case, researchers found that freshwater jellyfish appeared to cause an increase in chlorophyll levels in enclosures due to reductions in zooplankton abundance.However, it is important to note that these findings have nearly all been discovered in controlled experiments, and not in the Great Lakes in situ! The actual realized impact of freshwater jellyfish in the Great Lakes is largely unknown and unexplored.
Predators of the anhinga include large birds of prey such as eagles, hawks, and owls that may target both juvenile and adult birds. Additionally, mammals like raccoons and snakes could pose a threat to anhinga nests and young chicks.
These materials are called "elastic materials.".
Raw materials are materials that are used in the productions of goods and materials. They are the very basic materials and are feedstock for finished products.
