RAELM and PACM Program Analysis: Does the Online Presence Match the Experience?
Thu, 05/14/2020 - 10:52
Abstract: This is a research-based project that analyzes the Recreation, Adventure Education, and Leisure Management (RAELM) and Parks and Conservation Management (PACM) programs at Paul Smith’s College. The purpose of this research is to determine if there is a gap between the current advertised representation of the RAELM and PACM programs on the official Paul Smith’s College website and social media, and the experiences that current students within these programs have. The research includes an analysis of the programs’ current representation on the Paul Smith’s College website and social media, data collected from interviewing faculty involved in the program and surveying current students, and a literature synthesis of similar research projects and academic curriculums.

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

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.
