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.

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.
