“…White et al (2001) and Ballard and Krueger (2005) reported that an increase in the duration of cattle presence in an area increased the amount of manure in that area. The high soil-nutrient concentrations resulting from the concentration of feces in congregation areas may be transported in precipitation runoff and negatively impact aquatic ecosystems (Reynoldson 1987;Belsky et al 1999;Wang et al 2007). As the previous results were observed from research conducted on Western rangelands, these findings may not be applicable to management of Midwestern pastures because of differences in rainfall, climate, forage and soil types, and management.…”

Grazing at high stocking rates May Increase sediment and nutrient loading of streams pasture Through Transport in precipitation runoff and bank erosion. A 3-yr (2007)(2008)(2009)) grazing study was Conducted on 13 cool-season grass pastures to quantify effects of stocking rate and botanical composition on forage sward height, proportions of bare and manure-covered ground, and bank erosion adjacent to streams. Pastures ranged from 2 ha to 107 ha with stream Reaches of 306 m to 1778 m That has drained watersheds of 253 to 5660 ha. Bare and manure-covered ground Were Measured at 15.2-m distance perpendicular to the stream at 30.5-m intervals at up to 30 locations on each side of the stream by the line transect method in May, July, September, and November of each year.At the midpoint of the 15.2-m line, forage sward height was Measured with a falling plate meter (4.8 kg · m -2 ) and plant species identified. In November 2006, fiberglass pins (1.6 × 76.2 cm) 73.7 cm Were driven into the stream bank at 1-m intervals from the streambed to the top of the bank along 10 transect equidistant locations on each side of the stream bank erosion to measure During spring, summer, and fall of each year. Increasing pasture stocking rates Increased manure-covered ground and Decreased sward height, but did not Affect proportions of bare ground. The greatest, intermediate, and Least net soil erosion rates occurred During the winter / early spring, late spring / early summer, and late summer / fall seasons. Stocking rates Between measurements, Expressed as cow-days · m -1 stream, Were not related to bank erosion. Increasing stocking rates per unit of stream length will cover manure Increase and decrease forage sward height, but not Affect proportions of bare ground or bank erosion rates pasture adjacent to streams.THEREFORE, managing stocking rates May reduce nutrient loading of streams pasture.

“…Authors of previous studies have reported similar threshold declines in macroinvertebrate richness as N and P concentrations increased (Wang et al 2007, Weigel and. Wang et al (2007) The similarity between the Central Plains and Wisconsin stream TN and TP threshold concentrations and correlation coefficients suggest a broad agreement in threshold values for the mid-continental US. These threshold nutrient concentrations could be used to develop nutrient criteria for this region, and might be combined with experimental data to gain a better understanding about the main factors driving the threshold relationships .…”

“…However, all water-quality variables were positively correlated, so nutrient effects were difficult to separate from turbidity or sedimentation effects. Wang et al (2007) determined that nutrients accounted for only 22% of the variation explained by environmental factors in their study of benthic macroinvertebrate patterns across water-quality gradients. Catchment features, such as watershed area, and instream habitat features, such as silt substrate or embeddedness, explained ,42% of the variation.…”

“…First, we examined Spearman rank and Pearson correlations with a Bonferroni-corrected a (i.e., a divided by the number of dependent variables) to determine if richness metrics and mean taxa C:P were significantly correlated with water-quality measures (Wang et al 2007). Spearman rank correlations were always higher than Pearson correlations indicating nonlinear relationships among macroinvertebrate and water-quality data.…”

Abstract. N and P often limit primary and secondary production in ecosystems, but they also can cause eutrophication and negatively influence sensitive species above a certain level or threshold point. Aquatic biodiversity can have negative threshold relationships with water-quality variables at large scales, but the specific mechanism(s) driving these threshold relationships are not well established. We hypothesized that resource quality (i.e., C:P) might partly drive primary consumer (grazer and detritivore) richness thresholds by altering competitive interactions among species with differing resource demands, but might have less influence on predator richness. We estimated total N (TN), total P (TP), and turbidity thresholds for macroinvertebrate richness across trophic levels and feeding groups in Central Plains (USA) streams. We also determined if mean taxon body C:P of groups with diversity losses were negatively related to TP, a pattern that would suggest that eutrophic communities were dominated by a few species with high dietary P demands. Primary consumers were more sensitive to TN and TP (threshold mean = 1.0 mg N/L and 0.06 mg P/L) than secondary consumers (threshold mean = 0.09 mg P/L), a result supporting the resource quality hypothesis. Turbidity reduced richness regardless of feeding mode (threshold mean = 4.7 NTU), a result suggesting that turbidity and nutrient thresholds were driven by different factors. The TP-richness threshold could be driven partially by changes in food quality because the mean body C:P of shredding and collector-gathering taxa declined as TP increased (threshold mean = 0.07 and 0.75 mg P/L, respectively). Mean scraper C:P was not related to TP, a result indicating other factors might be responsible for the scraper richness threshold. Our results suggest that changes in resource quality could contribute to large-scale losses in biodiversity in nutrient-enriched lotic ecosystems. Within shredder and collectorgatherer macroinvertebrate feeding groups, P-rich food might allow faster growing taxa with high body P demands to out-compete slower growing taxa adapted to lower quality food resources. This pattern suggests that biotic integrity is directly linked to nutrients in streams and that toxicity, low dissolved O 2 , and increased turbidity might not be the only mechanisms leading to reductions in diversity as nutrient concentrations increase.
