Kingswood Lake Management Plan, Sarah Martina Tierney
Kingswood Lake Management Plan, Sarah Martina Tierney
Honors Theses and Capstones
High water quality and natural buffers exist on Kingswood Lake located in Brookfield, New Hampshire. A comprehensive lakes inventory (CSI) was recorded and health of the land, wildlife, and waterways were observed. Educational outreach was taken to inform the local community and to instruct them on proper stewardship of the land. A completed watershed management plan was constructed including key recommendation of limiting nitrogen loading in the area, checking septic systems for leaching, stabilizing shoreline from erosion, and establishing man-made rain gardens to help preserve water quality. The Kingswood watershed management plan acts as a guide for the town of …
Will The Exploratory Behavior Of Lobsters Decrease As They Become Familiar With Their Environment?, Marissa Cuda
Will The Exploratory Behavior Of Lobsters Decrease As They Become Familiar With Their Environment?, Marissa Cuda
Honors Theses and Capstones
Previous studies have shown that most lobsters have a home range in which they reside on a daily basis. The tendency for lobsters to reside in a particular area suggests that they have the ability to learn the characteristics of an area using exploratory behavior. We hypothesize that the exploratory behavior of juvenile lobsters will decrease as time spent in a novel environment increases; specifically exploratory behavior will decrease as the lobsters continuously learn the environment. Exploratory activity of juvenile lobsters was monitored in six lobsters using two separate maze complexities. Lobsters were video recorded and activity was measured based …
Filtering Efficiency And Feeding Mechanisms Of Daphnia Pulex On Microcystis Aeruginosa And Nannochloropsis, Elizabeth Orlowicz
Filtering Efficiency And Feeding Mechanisms Of Daphnia Pulex On Microcystis Aeruginosa And Nannochloropsis, Elizabeth Orlowicz
Honors Theses and Capstones
The filtering and feeding rate of Daphnia pulex from the Old Durham Reservoir, Durham, NH, were measured to determine the feeding efficiency on different concentrations of non-toxic Nannochloropsis (Class Eustigmatophyceae) and toxigenic cyanobacteria Microcystis aeruginosa. Direct observations of thoracic appendage beats and post-abdominal rejections were also measured at 5*105 and 106 cells mL-1 concentrations of Nannochloropsis and M. aeruginosa to examine the feeding mechanisms of the D. pulex. In the presence of increasing Nannochloropsis concentrations, the filtering rates decreased and the feeding rates increased. When exposed to M. aeruginosa, both the filtering and feeding …
