Phosphorus: Forms, Bioavailability, and Importance
Wednesday, November 8th at 6:30 PM
Finger Lakes Community College Stage 14 P_forms

Blue Green Algae Blooms: Is Phosphorous Responsible? Phosphorus is often described as the nutrient that limits primary production in temperate freshwater ecosystems. However, phosphorus exists in multiple forms and not all forms are equally useable by algae and phytoplankton for growth. Understanding common types of phosphorus and their relative availability to primary producers can be important knowledge for management of watersheds and lake water quality.

Hemlock Woolly Adelgid: A Film About the Loss of an Ecosystem
Filmaker: Chris Foito

It’s an insect few people have heard of – yet it is devastating our hemlock trees and the delicate forest ecosystems that depend upon them. The hemlock woolly adelgid is infesting our own backyards of New York and has already spread throughout the east coast of North America from the Carolinas up into Canada. The documentary, “The Hemlock Woolly Adelgid” aims to engage and educate the viewer on this often overlooked invasive species by explaining its past, present, and what could easily be the future if significant action is not taken
