A study on purple loosestrife

Species with life stages in both terrestrial and aquatic systems may be particularly likely to link the effects of trophic interactions across ecosystem boundaries. Using experimental wetlands planted with purple loosestrife Lythrum salicariawe tested the degree to which the bottom-up effects of floral density of this invasive plant could trigger a chain of interactions, changing the behavior of terrestrial flying insect prey and predators and ultimately cascading through top-down interactions to alter lower trophic levels in the aquatic community.

Mary Campbell and John Larch discussed their adventure of walking the full length miles of the Appalachian Trail from Georgia to Maine. She works on shoreline, streambank and wetland restoration using native plants.

Jen shared her experiences building rain gardens. The plants and soil in the rain garden facilitate infiltration and pollution removal. The Watershed Academy is a program that inspires high school biology students to become river stewards.

This year, students in 12 schools participated. Topics included statistical findings regarding the health of the Boyne River as well as other bodies of water nearby, future projects to be undertaken by the tribe, as well as suggestions for helping to improve the environment.

Gary has undertaken and completed the A study on purple loosestrife task of creating photographic slide shows, complete with music, of the entire Boyne River.

The project was completed in four phases: The first three phases are posted on YouTube where they can be viewed and enjoyed year around. Gary debuted the final phase for us on the large screen. We were able to sit back, relax and take in the sights and sounds of our celebrated river while eating snacks!

The trees are marked with plaques. We gratefully acknowledge the Sheets family and their dedication to the betterment of the Boyne River. This year two groups from Friends of the Boyne River collected water bugs from four locations on the river.

Although the study is not yet complete early signs bode well for excellent water quality due to the presence of pollution sensitive bugs such as stoneflies in great number.

The group found the project to be both fun and enlightening, results of the monitoring study will be posted once it is published. Big News for the Boyne River! This two-year research project is designed to connect citizen data input and automatic gauges to develop a real-time model that forecasts stream discharge, temperature and aquatic species habitat.

Currently, citizens may text water levels from five different data collection gauges. The scientists installed two of three additional automatically controlled sites in July that log temperature and flow data every 15 minutes and transmits it via cell phone every hour to a database.

They will also add digital temperature monitors to the water level gauges so citizens can text both water level and temperature. Both citizen and automatic gauge data connect to a high speed super computer at the University at Buffalo for analysis and prediction modeling.

Furthermore, the Boyne River citizen database is always viewable to anyone interested at www. Louis University As this study progresses, the collected data will potentially forecast river temperatures, water levels, and the distribution of certain aquatic species.

Pending success of the research, the system model can be beneficial to areas prone to flooding such as the Mississippi River or areas that see drought like California.

Visit frequently and text often because the more citizen data input, the better the river model, and thus more realistic ecosystem management. The crew used Adams big 16 foot canoe to carry a huge payload including bottles, cans, flip-flops, unopened beer, car tires, a yellow fun slide, barbecue grill parts and other garbage surprises.

The river trip was highlighted by many wildlife sightings with visits from a huge turtle, cedar wax wings, and kingfishers.What is hypothermia? Hypothermia is a physical condition that occurs when the body's core temperature falls below a normal ° F (37° C) to 95° F (35° C) or cooler.

The Problem with Purple Loosestrife The purple loosestrife is a flowering plant found in wetlands. The plant, which can grow as tall as two meters, is made up of a few square shaped, woody stems and hundreds of flower spikes.

The impact of the exotic plant purple loosestrife (Lythrum salicaria L.) on North American wetlands has been wide-spread. Thompson et al. () report that in many of these wetlands, purple loosestrife represents more than 50% of the in this study.
