Home Range Size and the Effects of Abiotic Conditions on Snowshoe Hares (Lepus americanus) in the Adirondacks.

Mon, 06/30/2014 - 19:01
Abstract: In northern boreal forest landscapes snowshoe hares (Lepus americanus) are an integral part of the ecosystem. They significantly impact vegetation, predators, and other prey species through their interactions. By understanding how snowshoe hares move on the landscape and their home range sizes. It can allow for insight into how they modify their behavior in relation to the distribution of natural resources, and predators on the landscape. The purpose of this research is to determine how snowshoe hare modify movement rate within home range in relation to abiotic conditions. Research took place within the Adirondack Visitor’s Interpretive Center, in the Adirondack Park, in northern New York State. Radiotracking was done in average 8 minute intervals multiple times a day in order to detect movement rates. Snowshoe hare was radio tracked and their locations were triangulated using an arithmetic mean. The locations were used to generate a home range with kernel density estimators and minimum convex polygons. Average snow depth had a negative effect on movement rate (p-value=0.006, r2=0.548). Movement rate was not affected by temperature (p-value=0.341, r2=0.003). Movement rate was also not affected by wind speed (p-value=0.696, r2=0.0515). Proximity of tracking location to hare in relation to movement rate showed a slight relationship (p-value=0.0009, r2=0.162). The snowshoe hare moved an average of 14.044 m/min for the total of 11 tracking days. The average home range size of the snowshoe hare 179.168 ha. The average radio telemetry error was. The snowshoe hare spent more time in coniferous habitat in comparison to mixed-deciduous (Χ2= 9.07177, p-value=0.011). The effects of abiotic conditions were close to expectations, and the home range size was larger than other published home range size studies of snowshoe hare within the Adirondack Park.

Food Plots for White-tailed Deer: Effects on the Browse Intensity of Commercial Tree Species in Western New York

Mon, 12/05/2011 - 10:09
Abstract: Throughout North America high densities of white-tailed deer (Odocoileus virginianus) are creating problems that affect humans as well as the natural environment; such as property damage (ex. deer/car accidents), crop damage due to browse, changes in forest species composition, as well as the creation of alternate stable states throughout the northeastern forests of the U.S. This study examined whether food plots for white-tailed deer are increasing, decreasing or having no effect on the browse intensity of commercial tree species in the northern hardwood/coniferous forests of western New York. Spring and summer browse intensity was determined at six sites throughout Wyoming, Cattaraugus, and Erie counties; three forested sites with food plots and three forested sites without food plots that were similar in species composition. The study found that food plots were causing an increase in browse intensity on commercial tree species to areas immediately adjacent (0-2 meters) to the food plots. However, further analysis that excluded measurements taken for subplots one at both food plot and non-food plot sites showed that non-food plot sites had a significantly greater proportion browsed. The findings suggest that if food plots are used as a management option for white-tails in western New York a buffer zone of at least 2 meters outside the food plot should be incorporated to account for the overflow of deer browse.

Designing a Multiple-Use Winter Recreation Trail System at the Paul Smith’s College Visitor Interpretive Center

Mon, 12/12/2011 - 10:13
Abstract: The purpose of this study is to investigate the interests and conflicts that arise between snowshoers, dogsledders, skijorers and cross country skiers. This study will be guided by interviews as well information from prior research performed on these types of users. Data will be collected by using interviews to determine the interests and conflicts of these users. This project will help give VIC managers recommendations andto provide information for a revised version of the winter trails map. The study and research that was done on user interests and conflicts to provide a higher level of enjoyment and safety for winter recreation trail users of the VIC for current and future generations. Results were collected by identifying recreational users of cross country skiing, snowshoeing, dog sledding and skijoring. Managers of recreational areas were also interviewed. The Paul Smith’s VIC would meet the needs of cross country skiers and snowshoers. The majority of the trails are suitable for cross country skiing and all of the trails would be suitable for the snowshoers depending on the type of snowshoer (secluded or controlled users). Dog-sledding and skijoring would not be suitable for the VIC due to the number of conflicts that are brought up when you bring dogs into the picture. Very few trails remain suitable for these two activities as well.

Changes in aquatic communities resulting from interactions between climate change and invasive aquatic plants in the Adirondacks.

Thu, 02/09/2012 - 11:26
Abstract: Global climate change can act synergistically with invasive species leading to shifts in ecosystem structure and function. We assessed how a rise in water temperature influenced the potential competitive advantage of an invasive aquatic plant, Eurasian watermilfoil, (Myriophyllum spicatum) over a co-occurring native species northern watermilfoil (M. sibiricum). We also examined the interrelationship between water temperature, watermilfoil, and the aquatic ecosystem including periphyton growth and zooplankton abundance. The study was conducted using replicated mesocosms (3785-liter), with water heaters used to provide a range of temperatures. We found that increasing water temperature promoted the likely competitive advantage of the invasive species, M. spicatum: Survival of M. sibiricum plants was lower than that of M. spicatum across all temperature treatments with a mean survival rate of 24% and 96% respectively. M. sibiricum also showed significantly slower rates of plant growth (mean growth of 3.3 cm compared to 7.6 cm for M. spicatum) and reduced vigor compared to M. spicatum, with an average of less than half the number of growing meristems. Zooplankton densities averaged over 20 times higher in mesocosms with M. sibiricum compared to those with the invasive M. spicatum. Periphyton biomass was best explained by water temperature with an increase in growth in warmer water. Our study confirms that in the face of global climate change, the invasive M. spicatum will continue to exert dominance over its native counterpart. Our results also provide compelling evidence that the combined effects of climate change and invasive aquatic plants can dramatically alter aquatic ecosystems.
