Lower St. Regis Lake Survey: A Comparative Study of Fish Population Structure and Function over Time
Thu, 12/13/2018 - 14:24
Abstract: Lake surveys are performed on bodies of water to provide a health analysis of fish populations over time. Lake surveys can be conducted in a variety of ways to attain specific data. Lower St. Regis Lake was surveyed to determine the fish community composition and to understand fish population traits. Using fyke nets placed at six predetermined locations for 24 hours, as well as fishing, we collected data for age, length (mm), weight (g), and parasites present. Data was analyzed in the lab using Excel to form graphs and tables to demonstrate our findings. Catch rates were lower compared to years before and comparing our data to New York State Department of Conservation data found that our length-at-age data was lower for the six-species sampled. Pumpkinseed and yellow perch were the only two species to have over twenty fish sampled. Decreased air temperatures brought in by a cold front during the week of our sampling may have been a reason for our lower number of fish caught. Mesh size is also a bias while using these nets as smaller fish can escape, and predatory fish can prey on smaller fish while in the net. Some species of fish such as black crappie may be more susceptible to capture due to its habit of associating with structure.

Homesteading for Beginners
Wed, 12/12/2018 - 14:51
Abstract: Homesteading isn’t just a movement, it’s a way of life. Our first research proposal was to create a guide to homesteading for beginners. Initial research showed there are countless types of homesteads and so we decided to research what homesteading is and the different ways you can homestead. Homesteading can be defined as a life of self sufficiency. But our research found that there can be many ways to achieve that goal.

A Paleolimnological study of precipitation variability in the Adirondacks over the last thousand years
Mon, 12/02/2013 - 20:40
Abstract: At present, most regional climate models anticipate wetter conditions by the end of this century, but a few models anticipate drier conditions. This study uses foresight to test these models, as well as describe the relationship between the dominant climate system in the region and past precipitation in the Adirondacks. Precipitation was inferred from diatom assemblages observed along a lake sediment core extending into the 1000 years. This study shows that abrupt, extreme wet events were common during the last 1000 years, and a relationship between the dominant climate system (North Atlantic Oscillation) and precipitation was irregular during the cool Little Ice Age but negatively associated during the warm Medieval Climate Anomaly. With temperatures in the Northeast projected to increase by 2-5 degrees C by 2100 AD, our study suggests the region may become more arid rather than wetter, opposite of what models currently suggest.

The Effects on Soil Caused by Garlic Mustard (Alliaria petiolata) in a Northern Hardwood Forest in the Northern Adirondack Mountains
Mon, 12/02/2013 - 10:54
Abstract: Plant invasions are thought to be among the worst causes of biological extinction and biodiversity loss in the modern world. With the United States spending upward of thirty four million dollars a year in attempts to control and repair the damages caused by invasive plants, not only are we feeling the biological effects, but we financially cannot afford to keep combating these invasive species (Barto and Cipollini, 2009). Garlic mustard (Alliaria petiolata) can invade multiple types of sites whether the soil is sandy or if a site has been disturbed. This invasive species will take over the understory and alter soil chemistry (Morris, McClain, Anderson and McConnaughay, 2012). This study aimed to look at how garlic mustard is affecting soils in the northern Adirondack Mountains in New York State. Although currently scattered and not very prevalent, there have already been changes to the soil chemistry. This study was conducted by setting up multiple plots within areas where garlic mustard was present and gathering soil to be used to test for nutrient values. It was found in this study that calcium, phosphorous, magnesium, potassium, sodium, aluminum and soil pH values changed due to the presence of garlic mustard.
