PPT-Damselfly Biodiversity in the Peconic River

Briannan Green Kylie Harrison Maheen Safian Andrew Serres Mentor Mr Robert Bolen Eastport South Manor JrSr 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. The complexity and rich diversity of life found in forests provides many vital services to human beings Nonetheless humans are destroying forest biodiversity at an alarming rate The conversion of forests to agricultural land overgrazing unsustainabl Alexis Richter.

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.

With dwindling biodiversity in the New York City marine ecosystem, it has become increasingly important to conserve the fragile populations that currently exist. One of the most significant reasons that the marine biodiversity has been decreasing is due to severe pollution. To combat pollution and decreasing biodiversity of the New York City waterways, groups such as the Billion Oyster Project have been adding adult oysters to different locations in the waters in hopes that they reproduce in the the new environment and can be reestablished as a keystone species in the New York waters. Before this can happen the water quality needs to improve. Luckily one oyster can filter between 20 to 50 gallons of water in one day. We want to compare present-day species richness in the Bronx River to the species richness recorded in a 2002-2004 study of the same area. Our results indicate that the present-day species richness in the Bronx river is 14, which has improved since the 2002-2004 study in which the species richness was 9.9. . Scottish Natural Heritage.

We compared our results to a 2015 study of biodiversity conducted by the NYS Department of Environmental Conservation. Our results indicate a decline in the species richness from 12.5 species in 2015 to 9 species in 2017 in the East River just south of the Williamsburg Bridge. This means that there is still a long way to go in restoring the NY Harbor to its former levels of biodiversity when native oysters were in abundance..
