“…Although the emissions from the runoff pond are substantially lower in comparison to the feedlot it should be noted that these emissions may display a strong degree of seasonal variability as the present emissions were collected when daily average air temperatures were 8.58C and heavy frost was reported on some occasions. A strong positive correlation between temperature and CH 4 emissions was recorded in nutrient retention ponds by Stadmark and Leonardson (2005) and an anaerobic swine lagoon consisting of a manure slurry by Sharpe and Harper (1999). Nonetheless, despite a predicted variability in CH 4 emissions over an annual period these emissions are still small in comparison to those of the feedlot.…”

X. 2008. Methane and ammonia emissions from a beef feedlot in western Canada for a twelve-day period in the fall. Can. J. Anim. Sci. 88: 641Á649. Commercial feedlot operations are becoming a mainstay in the Canadian beef industry. These large operations that typically raise thousands of animals at a time represent a large localized source of methane (CH 4 ) and of atmospheric pollutants such as ammonia (NH 3 ) and particulate matter. An inverse dispersion model was utilized to calculate CH 4 and NH 3 emissions from a commercial cattle feedlot and an adjacent runoff retention pond. The feedlot measurements were collected within the interior of the feedlot enabling a near continuous emissions record over the 12 d of the study period. Average daily emission estimates of CH 4 and NH 3 were 323 and 318 g animal(1 d (1 , respectively. The CH 4 emissions represent 4% of the gross energy intake (GEI) and NH 3 emissions represent 72% of the total N intake. Emissions from the runoff retention pond associated directly with the feedlot operation were approximately 2.7 and 2% of the daily average feedlot emissions of CH 4 and NH 3 , respectively.

“…Este estudo teve como objetivo avaliar a importância das regiões litorânea -considerando a contribuição das espécies dominantes Typha domingensis e Eichhornia azurea -no balanço de CO 2 na Lagoa Cabiúnas, contrastando com a região limnética. Métodos: O fluxo de CO 2 foi estimado por meio de regressões lineares das concentrações de CO 2 na atmosfera interna de câmaras estáticas, and chemistry, the presence of electron acceptors (redox conditions), pH, electrical conductivity (EC) and factors such as water depth and lake size (e.g., Casper et al, 2003, Stadmark andLeonardson, 2005;Frei et al, 2006;Repo et al, 2007;Loeb et al, 2007;Juutinen et al, 2009). As is observed in tropical lakes, some ecosystems can show CO 2 supersaturation for days or even for years (Marotta et al, 2009).…”

The role played by aquatic macrophytes regarding CO 2 balance in a tropical coastal lagoon (Cabiúnas Lagoon, Macaé, RJ)O papel desempenhado pelas macrófitas aquáticas em relação ao balanço de CO 2 em uma lagoa costeira tropical (Lagoa Cabiúnas, Macaé, RJ) 2 ) is an important atmospheric trace gas that is involved in both the biological carbon cycle and global warming. Inland waters -mainly lakes -contribute to C cycling and have been considered a large source of atmospheric CO 2 . However, scientific studies usually neglect lake morphometry and the presence of aquatic macrophytes in littoral zones, which have a great potential for CO 2 absorption and for C storage. This study aimed to evaluate the importance of the littoral region on the CO 2 balance in the Cabiúnas Lagoon, while also considering the contribution of the limnetic region and of Typha domingensis and Eichhornia azurea, prominent species in the area. Methods: CO 2 flux was estimated by a linear integration of CO 2 concentrations measured in the internal atmospheric of a single-component static closed chambers at the studied sites. The distribution of macrophyte stands throughout lagoon surface was taken into account to evaluate the effects of macrophytes on CO 2 supersaturation. Other factors were also measured throughout the sampling process to evaluate their relationship with CO 2 flux data by means of Akaike model selection criterion. The area covered by aquatic macrophytes at the Cabiúnas lagoon was estimated by profiles and transects. Results and discussion: CO 2 flux through the water surface ranged from -7.39 to 17.56 mgCO2m -2 h -1 . An emission pattern predominated, suggesting that water columns are CO 2 supersaturated at all sampling sites. Rates were similar among all the sampling sites, suggesting that aquatic macrophytes do not influence CO 2 saturation in the water column at Cabiúnas lagoon. On the other hand, CO 2 fluxes from macrophyte tissues showed a clear assimilation pattern. Influxes were higher in T. domingensis (-229.1 ± 320.9 mg CO2.m -2 .h -1 ) than in E. azurea stands (-43.8 ± 39.5 mg CO2.m -2 .h -1 ). Once these macrophytes covered a considerable area of the lagoon and CO 2 absorption strongly overwhelmed the emission processes, then we were able to extrapolate data from the total estimated area of the evaluated sites (75% of the Cabiúnas lagoon), which resulted in a net influx of 46.6 mg CO2.m -2 .h -1 . The strong Typha domingensis contribution to CO 2 absorption and other C cycling processes indicate that it is one of the most important species to Carbon cycling in the studied ecosystem. Thus, it is worth considering C cycling in lake littoral zones as a key process when estimating C balance in shallow aquatic ecosystems.

“…The underlying microbial processes affecting CO 2 and CH 4 production and emission are regulated by variables such as sediment and water temperature, oxygen availability, organic matter availability and composition, sediment and water chemistry, the presence of electron acceptors (redox conditions), pH, electrical conductivity (EC) and factors such as water depth and lake size (e.g. Stadmark and Leonardson 2005;Juutinen et al 2009;Repo et al 2007;Frei et al 2006;Loeb et al 2007;Casper et al 2003).…”

Shallow fresh water bodies in peat areas are important contributors to greenhouse gas fluxes to the atmosphere. In this study we determined the magnitude of CH 4 and CO 2 fluxes from 12 water bodies in Dutch wetlands during the summer season and studied the factors that might regulate emissions of CH 4 and CO 2 from these lakes and ditches. The lakes and ditches acted as CO 2 and CH 4 sources of emissions to the atmosphere; the fluxes from the ditches were significantly larger than the fluxes from the lakes. The mean greenhouse gas flux from ditches and lakes amounted to 129.1 ± 8.2 (mean ± SE) and 61.5 ± 7.1 mg m -2 h -1 for CO 2 and 33.7 ± 9.3 and 3.9 ± 1.6 mg m -2 h -1 for CH 4 , respectively. In most water bodies CH 4 was the dominant greenhouse gas in terms of warming potential. Trophic status of the water and the sediment was an important factor regulating emissions. By using multiple linear regression 87% of the variation in CH 4 could be explained by PO 4 3-concentration in the sediment and Fe 2?concentration in the water, and 89% of the CO 2 flux could be explained by depth, EC and pH of the water. Decreasing the nutrient loads and input of organic substrates to ditches and lakes by for example reducing application of fertilizers and manure within the catchments and decreasing upward seepage of nutrient rich water from the surrounding area will likely reduce summer emissions of CO 2 and CH 4 from these water bodies.
