Atlantic Salmon Egg Rearing Program (ASERP) Companion Curriculum Guide
No full textFive senior Environmental Studies majors from Mount Holyoke College collaborated to create this curriculum guide to be freely available to teachers who may be interested in participating in ASERP. We have written five lesson plans for five major themes we identified as critical to salmon education, using our own teaching and science backgrounds as guides. We offer this guide to be freely distributed throughout New England and beyond to anyone who wishes to utilize it. This project was undertaken with support from the US Fish and Wildlife Service, the Community-Based Learning Program and the Department of Biological Sciences at Mount Holyoke College, and the South Hadley Public Schools
Growing season mean ecosystem carbon dioxide fluxes and peak season vegetation at Mer Bleue Fertilization experiment 2001-2013
No full textSeasonal means of light saturated (PAR > 1000 micromol m-2 s-1) ecosystem carbon dioxide fluxes, temperatures and water table and peak season vegetation observations at Mer Bleue Fertilization experiment, Ottawa, Canada. CO2 fluxes were measured with a transparent, climate-controlled chamber and shrouds during May-August in 2001-2011. During the time period, most of the collars in Experiment 1 (control O and treatments PK, 5N, 5NPK started in 2000; 10NPK, 20NPK in 2001) were measured in 2001, 2003, 2005, 2008, 2009, 2011 and most collars in Experiment 2 (Control X and treatments 10N, 20N started in 2005) in 2008, 2009, 2011. Seasonal means were based on approximately 10 flux measurements from May-August (see MBfert_NetCO2Exchange_instantflux_2001-2011.xls). Vegetation measurements include the height of the shrub canopy, and Sphagnum and Polytrichum moss cover recorded in July 2000-2013. During the time period, the collars in Experiment 1 (control O and treatments PK, 5N, 5NPK 10NPK, 20NPK) were measured in 2001, 2003, 2005, 2007, 2008, 2009, 2011, 2012, 2013 and the collars in Experiment 2 (Control X and treatments 10N, 20N) in 2005 (moss cover only), 2007, 2008, 2009, 2011, 2012, 2013. Also included are estimates for plant area indices (LAI) 2008, 2009, 2011 (See methods).Annual N application levels as NH4NO3 since the beginning of the respective treatments: 5 (1.6 g N m-2), 10 (3.2 g N m-2) and 20 times (6.4 g N m-2) ambient summer time wet N deposition (0.8 g m-2y-1 in 2000) with or without P (5.0 g m-2) and K (6.3 g m-2) as KH2PO4. Distilled water served as control. Nutrient solutions were applied every 3 weeks May-August on triplicate 3 x 3 m plots.
