Healthy aquatic ecosystems depend upon many factors. One important factor is the chemical balance present in the ecosystem.. Aquatic ecosystems are susceptible to many chemical changes. Usually if the chemistry of a “healthy” ecosystem changes, signs of this change will include sensitive organisms quickly declining in number or disappearing. These types of organisms are called .

[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. Being extremely skilled fliers and having almost a complete 360 view, they keep pesky mosquitoes, disease-spreading . Briannan Green, Kylie Harrison, Maheen Safian, Andrew Serres. Mentor: Mr. Robert Bolen. Eastport South Manor Jr-Sr High School. . Abstract. 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..
