“…The N-laden runoff often flows across the nursery to finally reach bodies of water, contributing to the increasing reactive N load of surface and groundwater resources of the country (Galloway et al 2004). Higher NO 3 concentration in the rivers of the U.S. is a major cause of eutrophication in coastal waters (Turner and Rabalais 1994;Day et al 2003).…”

Denitrification and nitrous oxide emissions from riparian forests soils exposed to prolonged nitrogen runoff

Compared to upland forests, riparian forest soils have greater potential to remove nitrate (NO 3 ) from agricultural runoff through denitrification. It is unclear, however, whether prolonged exposure of riparian soils to nitrogen (N) loading will affect the rate of denitrification and its end products. This research assesses the rate of denitrification and nitrous oxide (N 2 O) emissions from riparian forest soils exposed to prolonged nutrient runoff from plant nurseries and compares these to similar forest soils not exposed to nutrient runoff. Nursery runoff also contains high levels of phosphate (PO 4 ). Since there are conflicting reports on the impact of PO 4 on the activity of denitrifying microbes, the impact of PO 4 on such activity was also investigated. Bulk and intact soil cores were collected from N-exposed and non-exposed forests to determine denitrification and N 2 O emission rates, whereas denitrification potential was determined using soil slurries. Compared to the non-amended treatment, denitrification rate increased 2.7-and 3.4-fold when soil cores collected from both N-exposed and non-exposed sites were amended with 30 and 60 lg NO 3 -N g -1 soil, respectively. Net N 2 O emissions were 1.5 and 1.7 times higher from the N-exposed sites compared to the non-exposed sites at 30 and 60 lg NO 3 -N g -1 soil amendment rates, respectively. Similarly, denitrification potential increased 17 times in response to addition of 15 lg NO 3 -N g -1 in soil slurries. The addition of PO 4 (5 lg PO 4 -P g -1 ) to soil slurries and intact cores did not affect denitrification rates. These observations suggest that prolonged N loading did not affect the denitrification potential of the riparian forest soils; however, it did result in higher N 2 O emissions compared to emission rates from non-exposed forest soils.

“…Ecologists, climatologists, and geomorphologists have identified a range of different modes of pulsing, which seem to be essential components of the behavior of coastal systems. These events range from switching of river channels in deltas that takes place on the order of 500-1000 years to daily tides and includes great floods that occur a few times a century, strong storms such as hurricanes occurring on decadal scales, annual river floods, and frontal passages (Day et al, 1995(Day et al, , 1997(Day et al, , 2003Viles and Goudie, 2003;Yáñez-Arancibia et al, 2004.…”

“…Organisms within the Gulf are continually exposed to a multitude of environmental and anthropogenic stressors, such as climate change, hurricanes, hypoxia, pollution, oil spills, shipping activity, geophysical surveys, and commercial fishing (Diaz & Solow 1999, Day et al 2003, Karnauskas et al 2013. The recognition of noise pollution as a stressor for marine organisms (Southall et al 2007, Hildebrand 2009, Slabbekoorn et al 2010, Ellison et al 2012) and the concerns for synergistic cumulative impacts of multiple stressors on marine ecosystems (Sih et al 2004, Crain et al 2008) warrant the need for evaluating noise levels and investigating the possible im pacts of anthropogenic noise in the Gulf of Mexico.…”
