An Assessment of Heavy Metal Concentrations in Adirondack Waterfowl

Thu, 04/28/2016 - 22:53
Abstract: We analyzed heavy metal concentrations in waterfowl liver and breast tissue from ducks harvested within the Adirondack Park from October 3 to November 13, 2015. Interspecific, intersex, and feeding behavior variation in heavy metal concentrations were assessed. Waterfowl from two feeding behavior groups (diving and dabbling) were harvested from the watershed within a 50 mile radius of Paul Smith’s, New York. Harvested waterfowl species included mallard (Anas platyrhynchos), American black duck (Anas rubripes), common merganser (Mergus merganser), ring-necked duck (Aythya collaris), bufflehead (Bucephala albeola), and hooded merganser (Lophodytes cucullatus). Legal harvest of these species during regulated New York State duck hunting season allows for permissible use of internal organs for heavy metal determination. Dry weight (mg/kg) of digested liver and breast tissue samples were analyzed using atomic absorption spectroscopy. Due to unknown laboratory error, absolute concentration values were inaccurate, thus, rendering accurate analyses unfeasible. However, relative observable trends were able to be assessed given our data’s high precision. Analyte concentrations were significantly greater in liver tissues and there were significant differences between species. Variation in mercury, lead, bismuth, cadmium, chromium, and zinc concentrations in waterfowl serve as an indicator of the presence, cycling, bioaccumulation, and temporal trends of these metals in northeastern aquatic habitats.

Jenkins Café

Wed, 04/27/2016 - 07:25
Abstract: Jenkins’ Café will be a quick service café establishment located at the base of Jenkins Mountain, along the trail systems of the Visitor’s Interpretive Center (VIC). The VIC has recently become an entity of Paul Smith’s College, allowing greater flexibility of management, away from State jurisdiction. About three miles into the VIC’s trail system is the base of Jenkins’ Mountain, the location for Jenkins’ Café. Jenkins’ Café will serve local residents, Paul Smith’s College students, and VIC visitors’ quick meals consisting of sandwiches, soups, and salads while they utilize the VIC trails. Warm and cold beverages will also be available for service, including a small selection of beer and wine. Hikers, cross-country skiers, bird watchers, snowmobilers, and anyone participating in any VIC activities, can enjoy these fares when they arrive at Jenkins’ Café.
