“…Ungulate trampling appeared to increase soil bulk density and the physiochemical properties by hoof action (Table 1). Ungulate trampling intensified soil compaction and generated anaerobic conditions that are favorable for denitrification (Menneer et al 2005). But the low SWC in the experimental region restricted the generation of denitrification to a large extent.…”

-1 from the native and grazed LC steppe, respectively. Grazing activities suppressed N 2 O production. In the growing season, soil moisture was the primary driving factor of N 2 O fluxes. The high seasonal variation of N 2 O fluxes was regulated by the distribution of effective rainfall, rather than precipitation intensity. Air temperature or soil temperature at 0, 5, and 10 cm depth was the most restricting factor of N 2 O fluxes in the nongrowing season.

“…According to Jacob (1987), the tread of a cattle of 600 kg causes a pressure of 4-5 kg cm -2 on the topsoil. The resulting compaction may lead to retarded water infiltration and gas diffusion, increasing the risk of surface runoff and elevated emissions of gases like the greenhouse gas nitrous oxide (Menneer et al 2005;Mulholland and Fullen 1991;Oenema et al 1997;van Groenigen et al 2005). However, compaction can also have positive effects: it is expected that treading might compensate for the prohibition of rolling in spring on nature protected grassland (Benke and Isselstein 2001).…”

Phytodiversity of temperate permanent grasslands: ecosystem services for agriculture and livestock management for diversity conservation

Plant diversity has been reported to increase productivity. Farming practices aiming at conserving or increasing plant diversity are, however, usually less profitable than conventional ones. In this review, we aim to find reasons for this discrepancy, discuss ecosystem services of grassland phytodiversity that are useful for farmers, and ways of livestock management most beneficial for diversity. Under agricultural conditions, a clear effect of species richness on a site's primary or secondary production has not yet been demonstrated. Reasons could be that species numbers in permanent grassland are above the threshold of five species found effective in experimental plots or that the conditions are more in equilibrium with management than in weeded experimental plots. Other diversity effects on production stability, nutrient and water retention or product quality might convince farmers to increase diversity. However, these should be tested in agricultural situations, as most research has again been carried out in experimental plots. To enhance phytodiversity, grazing has been found superior over mowing, as selective grazing, treading and excreta deposition increase the heterogeneity of a sward and thus the niches available. Especially rotational grazing with intermediate intensity may be advantageous for phytodiversity. However, complex interactions between environmental conditions, sward composition, management and livestock behaviour make it difficult to forecast grazing effects. Thus, ecological and agricultural researchers should cooperate more, e.g. either in interdisciplinary projects or by hiring researchers from the respective other profession and thus diversifying research groups, in order to integrate agricultural management into biodiversity research and biodiversity measurements into agricultural research to 123Biodivers Conserv (2011) 20:3317-3339 DOI 10.1007 advance our understanding of how to make conservation and enhancement of grassland phytodiversity both feasible and sustainable.

“…Compared to ordinary pastures, which are used for grazing during summer time, a much higher number of animals are present on a small area for a relatively long period. This causes a reduction in soil aeration through soil compaction (Menneer et al, 2005). The presence of animals is accompanied by a high input of organic material through excrements which consequently stimulates microbial metabolism, increases oxygen demand and supports the occurrence of anoxic (micro)sites in the soil (Šimek et al, 2006).…”

Abstract. While the importance of anaerobic methane oxidation has been reported for marine ecosystems, the role of this process in soils is still questionable. Grasslands used as pastures for cattle overwintering show an increase in anaerobic soil micro-sites caused by animal treading and excrement deposition. Therefore, anaerobic potential methane oxidation activity of severely impacted soil from a cattle winter pasture was investigated in an incubation experiment under anaerobic conditions using 13 C-labelled methane. We were able to detect a high microbial activity utilizing CH 4 as nutrient source shown by the respiration of 13 CO 2 . Measurements of possible terminal electron acceptors for anaerobic oxidation of methane were carried out. Soil sulfate concentrations were too low to explain the oxidation of the amount of methane added, but enough nitrate and iron(III) were detected. However, only nitrate was consumed during the experiment. 13 C-PLFA analyses clearly showed the utilization of CH 4 as nutrient source mainly by organisms harbouring 16 : 1ω7 PLFAs. These lipids were also found as most 13 Cenriched fatty acids by Raghoebarsing et al. (2006) after addition of 13 CH 4 to an enrichment culture coupling denitrification of nitrate to anaerobic oxidation of methane. This might be an indication for anaerobic oxidation of methane by relatives of "Candidatus Methylomirabilis oxyfera" in the investigated grassland soil under the conditions of the incubation experiment.
