Bringing metacognition onto college campuses is a transformational experience for students and faculty as well as their institutions. In this chapter, we share a collection of metacognitive activities and describe their value in and outside of the classroom based upon our experiences in the community college setting. These activities are easily implemented and help students take ownership of their learning.

This chapter presents the leadership journeys of five faculty who participated in the SAGE 2YC: Faculty as Change Agents project. These faculty stories illustrate the influence of the project on their leadership and work as mid-level administrative or grassroots leaders. Key to the project was the explicit inclusion of leadership development in the professional development (PD). Learning about organizational frames and leadership approaches, the experience of faculty participants designing and leading their own workshops, and the resulting community of practice contributed to the leadership development of faculty participants. Implications and recommendations for leadership development of faculty members, critically important for colleges, concludes the chapter.

Leading community college change initiatives from midlevel leadership positions is challenging. This chapter reviews the experiences of two midlevel leaders who led change on their campuses. They describe the work of their leadership efforts, including their relationships with faculty, administrators, students, and the challenges, rewards, and lessons learned.

We compared processing and fate of dissolved N[O.sub.3.sup.-] in two New England salt marsh ecosystems, one receiving natural flood tide concentrations of ~1-4 [micro]mol N[O.sub.3.sup.-]/L and the other receiving experimentally fertilized flood tides containing ~70-100 [micro]mol N[O.sub.3.sup.-]/L. We conducted simultaneous [sup.15]N[O.sub.3.sup.-] (isotope) tracer additions from 23 to 28 July 2005 in the reference (8.4 ha) and fertilized (12.4 ha) systems to compare N dynamics and fate. Two full tidal cycles were intensively studied during the paired tracer additions. Resulting mass balances showed that essentially 100% (0.48-0.61 mol N[O.sub.3]-N x [ha.sup.-1] x [h.sup.-1]) of incoming N[O.sub.3.sup.-]] was assimilated, dissimilated, sorbed, or sedimented (processed) within a few hours in the reference system when N[O.sub.3.sup.-] concentrations were 1.3-1.8 [micro]mol/L. In contrast, only 50-60% of incoming N[O.sub.3.sup.-] was processed in the fertilized system when N[O.sub.3.sup.-] concentrations were 84-96 [micro]mol/L; the remainder was exported in ebb tidewater.

Abstract. We compared processing and fate of dissolved NO3- in two New England salt marsh ecosystems, one receiving natural flood tide concentrations of ∼1-4 μmol NO3-/L and the other receiving experimentally fertilized flood tides containing ∼70-100 μmol NO3-/L. We conducted simultaneous 15NO3- (isotope) tracer additions from 23 to 28 July 2005 in the reference (8.4 ha) and fertilized (12.4 ha) systems to compare N dynamics and fate. Two full tidal cycles were intensively studied during the paired tracer additions. Resulting mass balances showed that essentially 100% (0.48-0.61 mol NO3-N∙ha-1h∙-1) of incoming NNO3- was assimilated, dissimilated, sorbed, or sedimented (processed) within a few hours in the reference system when NO3- concentrations were 1.3-1.8 μmol/L. In contrast, only 50-60% of incoming NO3- was processed in the fertilized system when N03 concentrations were 84-96 μmol/L; the remainder was exported in ebb tidewater. Gross NO3- processing was ∼40 times higher in the fertilized system at 19.34-24.67 mol NNO3-N∙ha-1∙h-1. Dissimilatory nitrate reduction to ammonium was evident in both systems during the first 48 h of the tracer additions but <1% of incoming 15NO3- was exported as 15NH4+. Nitrification rates calculated by 15NO3- dilution were 6.05 and 4.46 mol∙ha-1∙h-1 in the fertilized system but could not be accurately calculated in the reference system due to rapid (<4 h) NO3- turnover. Over the fiveday paired tracer addition, sediments sequestered a small fraction of incoming NO3-, although the efficiency of sequestration was 3.8% in the reference system and 0.7% in the fertilized system. Gross sediment N sequestration rates were similar at 13.5 and 12.6 mol∙ha-1∙d-1, respectively. Macrophyte NO3- uptake efficiency, based on tracer incorporation in aboveground tissues, was considerably higher in the reference system (16.8%) than the fertilized system (2.6%), although bulk uptake of NO3- by plants was lower in the reference system (1.75 mol NO3-∙ha-1∙d-1) than the fertilized system (-10 mol NO3-∙ha-1∙d-1). Nitrogen processing efficiency decreased with NO3- load in all pools, suggesting that the nutrient processing capacity of the marsh ecosystem was exceeded in the fertilized marsh.

We compared processing and fate of dissolved NO3- in two New England salt marsh ecosystems, one receiving natural flood tide concentrations of approximately 1-4 micromol NO3-/ L and the other receiving experimentally fertilized flood tides containing approximately 70-100 micromol NO3-/ L. We conducted simultaneous 15NO3- (isotope) tracer additions from 23 to 28 July 2005 in the reference (8.4 ha) and fertilized (12.4 ha) systems to compare N dynamics and fate. Two full tidal cycles were intensively studied during the paired tracer additions. Resulting mass balances showed that essentially 100% (0.48-0.61 mol NO3-N.ha(-1).h(-1)) of incoming NO3- was assimilated, dissimilated, sorbed, or sedimented (processed) within a few hours in the reference system when NO3- concentrations were 1.3-1.8 micromol/L. In contrast, only 50-60% of incoming NO3- was processed in the fertilized system when NO3- concentrations were 84-96 micromol/L; the remainder was exported in ebb tidewater. Gross NO3- processing was approximately 40 times higher in the fertilized system at 19.34-24.67 mol NO3-N.ha(-1).h(-1). Dissimilatory nitrate reduction to ammonium was evident in both systems during the first 48 h of the tracer additions but <1% of incoming 15NO3- was exported as 15NH4+. Nitrification rates calculated by 15NO3- dilution were 6.05 and 4.46 mol.ha(-1).h(-1) in the fertilized system but could not be accurately calculated in the reference system due to rapid (<4 h) NO3- turnover. Over the five-day paired tracer addition, sediments sequestered a small fraction of incoming NO3-, although the efficiency of sequestration was 3.8% in the reference system and 0.7% in the fertilized system. Gross sediment N sequestration rates were similar at 13.5 and 12.6 mol.ha(-1).d(-1), respectively. Macrophyte NO3- uptake efficiency, based on tracer incorporation in aboveground tissues, was considerably higher in the reference system (16.8%) than the fertilized system (2.6%), although bulk uptake of NO3- by plants was lower in the reference system (1.75 mol NO3-.ha(-1).d(-1)) than the fertilized system (approximately 10 mol NO3-.ha(-1).d(-1)). Nitrogen processing efficiency decreased with NO3- load in all pools, suggesting that the nutrient processing capacity of the marsh ecosystem was exceeded in the fertilized marsh.
