Analysis of common water sampling techniques used to assess lake trophic state

Sat, 12/05/2015 - 00:21
Abstract: Volunteer lake management programs (VLMPs) across the country employ different surface water sampling techniques to establish long-term trends in nutrient availability and trophic state. The three most common techniques are a surface grab (SG), 2m integrated tube sampler (IT), and a discrete sampler, such as a Van Dorn or Kemmerer bottle deployed to a depth of 1.5m (DD). These various sampling techniques vary not only in depth, but also in cost and ease of use. The objectives of my study are to 1) determine if there is a statistical difference in chlorophyll-a (chl-a) and total phosphorus (TP) concentration obtained between the three different sampling techniques, 2) determine if the treatment effect (sampling device) varies over time, 3) determine which method has the least amount of variability, and 4) determine if sampling technique ultimately influences trophic state classification. The study was conducted on Upper St. Regis Lake, Paul Smiths, New York. I collected 10 samples from the lake using the three different techniques during the months of June – August, 2015. I found a significant difference in chlorophyll-a concentration between sampling techniques during June and July, and during the month of July for TP. The three sampling techniques yielded similar variability for chlorophyll-a but significantly different variability for TP. Ultimately, the trophic status rating for Upper St. Regis was not effected by sampling technique. My study suggests that VLMP should utilize a SG or IT rather than a costly DD sampler.

Limnological Report of Marvin (Potters) Pond

Thu, 04/30/2015 - 09:51
Abstract: Long term data of limnological conditions is crucial to understand lentic freshwater ecosystems. Marvin (Potters) pond is a 2.04 hectare kettle pond located in Franklin County, New York in the Northern Adirondack Park. There have been numerous short studies of the pond over the past 30 years but the pond has never been intently monitored to date. The pond is assumed to be meromictic by the NYSDEC. The objectives of this study are to 1) calculate the morphometry of the pond and its watershed; 2) the determination of the trophic status of the pond; 3) to document the chemical composition of the pond, particularly as it relates to acidity and acid neutralizing capacity; 4) to document the annual dynamics of temperature and dissolved oxygen. Evidence from profile data on dissolved oxygen and total iron suggests that the pond is monomictic with the capability to be meromictic under certain climatic conditions. The mixing period of the pond occurred in the month of November. The morphometry of Marvin pond was found to have a conical cross sectional area and large depth for the surface area of the pond. The trophic state of Marvin pond was found to be eutrophic for chlorophyll-a and total phosphorus concentrations but mesotrophic for the secchi disk reading. The acidity of the pond was found to be high with a low buffering capacity.

Trophic status of Lake Placid over the past 2740 + 30 years inferred by sub-fossil diatom analysis.

Thu, 04/30/2015 - 11:07
Abstract: The hypothesis of this study was that human activity in the Lake Placid watershed would cause changes in the lakes trophic status. Trophic status was inferred by changes in diatom assemblages over time. This analysis shows that an unusual increase in Asterionella and Tabellaria has occurred within the past 200 years. Both of these species are indicators of higher trophic status, so their increase in numbers indicates a recent increase in trophic status (Stager 2001, Rawson 1956, Stevenson et al, 1982). Loss on ignition tests were used to determine the organic content of samples from two cores. These tests showed that organic content has varied in the past, however changes observed in the upper 20 cm of the record for Lake Placid and Wolf Lake suggest that human activity impacted the lake. The data collected in this study supports the hypothesis that human settlement in the Lake Placid watershed has changed its trophic status.

Interactive Electronic Education at the Paul Smith’s Visitor Interpretive Center

Tue, 05/05/2015 - 16:30
Abstract: The use of electronics in an educational setting is a debated topic, but certain kinds of programs are becoming more prominent. The purpose of this study is to examine how interactive electronic environmental education programs are used to facilitate environmental education, and attempting to determine whether or not the Paul Smith’s College Visitor Interpretive Center (VIC) could make use of them. Through interviews with key members of the Paul Smith’s College and the VIC as well as surveying the general public of both communities it was determined that these forms of educational programs were not in high demand by the users of the VIC, but electronic recreation tools were.

Management of the Invasive Species; a recommendation to the Paul Smith's College VIC

Wed, 05/06/2015 - 08:10
Abstract: This research looks at invasive species that are harming the Adirondack region. By examining both invasive species on land and water we can make connections to what the problematic issues are. By understanding the species, information can be gathered to educate the public on what to look for and how to prevent the species from spreading. Paul Smith’s College VIC is looking for new ideas to incorporate for both the campus and local community. The focus of this project is to look at what the VIC has done in the past, present and future in terms of education and programs. Creating a new program and addressing an environmental issue are two key components that we hope to make the VIC a stronger addition to the area.

The Effect of Temperature and pH on the Growth of Variable-leaf Milfoil (Myriophyllum heterophyllum)

Tue, 12/04/2012 - 18:03
Abstract: A fundamental part of invasion biology is the prediction of the potential spread of nonindigenous species (NIS). This is due to the negative ecological, economic and human-health effects that NIS may cause. Variable-leaf Milfoil (Myriophyllum heterophyllum), a highly invasive NIS to the Northeast, is native to southern U.S. states from Florida to New Mexico, and has since spread to North Dakota and southwestern Quebec without becoming invasive to those areas. Variable-leaf milfoil is invasive to the Adirondacks in northern New York State and is spreading at a rapid pace. This study questions whether temperature and pH have an effect on the growth of Variable-leaf milfoil. In this laboratory experiment, the growth of 80 Variable-leaf Milfoil fragments was examined in warm (33.1275°C) and cold (23.135°C) temperatures, combined with 10 pH treatments. Fragments showed increased growth in cold water when compared to the warm temperature treatment, and no relationship was shown between temperature and pH treatment in relation to growth.

A Land Management Plan for the Gottemoeller Family Farm

Thu, 12/06/2012 - 09:58
Abstract: Private landowners own property that is used for a variety of purposes. A management plan can help them realize their goals. This management plan focuses on two main goals. One is to maximize the sustainable out put of black walnut and other quality hardwoods. The other is creation of quail habitat to increase the carrying capacity of bobwhite quail on the farm. Using aerial photos and field visits, the property was divided into ten different management units. Some units have a forestry focus and others have a quail habitat focus or both. A Wildlife Habitat Appraisal Guide was used to evaluate the existing habitat and to identify which elements need to be improved. Peer reviewed research and agency technical expertise were used to identify which practices will improve the limiting elements for quail habitat. A Forest Plan developed by a professional forester with the Missouri Department of Conservation was incorporated into the farm Management Plan.
