What is the most likely reason for this decline in aquatic species in virginia's southern watershed?

Watershed is a land which receives water from all possible water sources. These regions are composed of land and water. These regions are typically shallower so allows the deposition of water from sources like river, lakes, ponds and other water body and this water gets drained out into a large water body.  Virginia's Southern Watershed also acquires water from various sources. The decline in the aquatic species is because of the introduction of invasive species in the watershed obtained from different water sources. These  invasive species are competent with native species for resources or they have a predatory instinct therefore, this results in the decline in the native species.

explanation:

the framers of the constitution insisted that federal judges be nominated instead of elected due to their desire to have judges above the shifting whims of the masses.

the hope, whether achieved or not, was that federal judges would only be beholden to the law and that by not having judges be elected, they would be protected if that law dictated an outcome that ran counter to popular opinion.
