Our hypothesis was that if there is a change from freshwater to saltwater, then the tidal plant species in each area will differ. The data collected from our experiment helped support our hypothesis. In our findings we saw that in the freshwater location, there was a greater amount of biodiversity and the plants were generally larger. On the other hand, we saw that in the saltwater location, the banks had less biodiversity and consisted with only Phragmites. One explanation for this is for the fact that the abundance of freshwater in the freshwater location allowed for a large variety of large plants to live in this area. However, only a thin layer of freshwater on the surface of the water was present at the saltwater location, which minimized the diversity of plant life that could live in this area. This minimized the competition in this area, allowing it to be overrun by Phragmites plants. . Biodiversity . r. efers to . the amount of genetic diversity in ecosystems. .

[8] Most if not all life forms play a vital role in the Peconic River, and because of the nature of how dragonflies develop and mature it is important to monitor this species. Dragonflies have a significant and positive role in maintaining ecological homeostasis.

This project was based on the objective of attempting to find a change in biodiversity in our local Peconic River, and to detect any fluctuations in it from previous years. Our 17 out of 20 samples were processed and identified in the barcode system. We found a complete lack of diversity in the various damselfly species inhabiting the Peconic River. Additional studies will need to be completed to determine if there is an underlying environmental factor impacting damselflies. The effect of specific, multiple species being missing from the Peconic ecosystem has the potential to have a harmful effect on humans living in the community around it. For instance, damselflies eat “nuisance” insects that exist in the area. A decrease in the biodiversity of the species means that there is a high probability of disease transmission, unknown changes in the food chain, and a decrease in the quality of the river system..
