Impacts a/Sedimentation/rom Oil and Gas Development on Stream Macroinvertebrates in Two Adjacent Watersheds a/the Allegheny National Forest a/Northwestern Pennsylvania - The Allegheny National Forest (ANF), located in northwestern Pennsy Ivania, is a multiuse forest combining commercial development with recreational and conservation activities. As such, portions of the ANF have been heavily logged and are now the subject of widespread oil and gas development. This rapid increase in oil and gas development has led to concerns about sediment runoff from the dirt and gravel roads associated with development and the potential impact on the aquatic biota of the receiving streams. We examined and compared the benthic macroinvertebrate communities in two adjacent watersheds of similar size and topography in the ANF; the Hedgehog Run watershed has no oil and gas development, while the adjacent Grunder Run watershed has extensive oil and gas development. In Hedgehog and Grunder Run, we collected monthly kicknet samples from riffles and glides at two sites from April to October 2010. At the same intervals, we measured standard water quality parameters, including conductivity and turbidity. Preliminary results have indicated much higher turbidity in Grunder Run, but little difference in the diversity and abundance of benthic macro invertebrates inhabiting the two streams.

This book was released on 2005 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Macroinvertebrates in urban streams in Ohio are potentially compromised by habitat loss, by the annual peak discharge event, and by degraded water quality. The Mill Creek in Southwest Ohio is a significantly channelized river that collects storm water runoff, wastewater treatment plant effluent, permitted dischargers, sanitary sewers, and combined sewers. Channelization areas have had 12-40 years to re-grow. Most of the riparian zone, although narrow, is lined with trees that shade the channel. The result is eutrophication by nutrient loading, some toxic chemical spills, and habitat simplification. This study was designed to show the relative impacts of habitat and water quality on the macroinvertebrate community in a multi-stressed urban stream. Possible limiting factors were quantified and evaluated along the main-stem of the Mill Creek and related to the macroinvertebrates five times over the summer of 2000. The habitat was characterized using the Ohio EPA's QHEI, the estimated peak flow, and pebble counts. Water quality was quantified by the nutrient concentrations found. Both habitat and water parameters were compared to macroinvertebrate density, taxa richness, and the calculated metric, invertebrate community index. Data was collected for base flow in the summer and autumn of 2000-2001. The QHEI and the ICI were linearly related over transects done in four non-consecutive years within a decade. Multiple regression showed several habitat variables correlated to taxa richness. ANOVA identified average species richness was significantly impacted by both water quality and habitat variables. A non-parametric method (detrended canonical correspondence analysis) separated the determinants for invertebrate communities along a nutrient (19.1% of variance) and habitat axis (11.1% of variance).

This book was released on 2016 with total page 171 pages. Available in PDF, EPUB and Kindle. Book excerpt: Southern Appalachian watersheds of the United States are negatively affected by pesticides and fertilizers used in row crop agriculture. The objective was to determine if the amount of row crops is connected to changes in aquatic biotic assemblages draining the Nolichucky River watershed in east Tennessee. The hypothesis was the amount of row crops will negatively correlate with indices of biotic integrity (IBI) metrics for fish and benthic macroinvertebrates indicating healthy aquatic communities. For 18 sample sites in 2014 and 2015, IBI metrics were calculated. Water quality and elevation measurements were made before conducting IBIs. To assess changes in and amounts of land use/land cover (LULC), maps from 1999 to 2014 were produced with Landsat satellite imagery. Pollutant estimates (sediment, phosphorus, and nitrogen) were calculated using the Soil & Water Assessment Tool (SWAT) model. The area of row crops increased since 1999 (39 km2 in 1999 to 71 km2 in 2014). A principal component analysis was performed on LULC measurements from different scales (local, reach and catchment), water quality data, and elevation to produce a reduced set of explanatory variables that were uncorrelated but could be associated with IBI metrics. A canonical correspondence analysis associated fish metrics with LULC types: Impervious surfaces, non-row crop fields, and forest (p = 0.04 for axis 1 eigenvalue, p = 0.05 for species-environment correlations). For the benthic macroinvertebrate metrics, nonmetric multidimensional scaling found metrics indicative of poor stream health (percentage of oligochaetes and chironomids, percentage of nutrient tolerant organisms) were strongly positively associated with increasing use of row crops, impervious surfaces (p ≤ 0.01), and pollutant estimates (p ≤ 0.004). A redundancy analysis found increasing pollutant estimates were associated with fish metrics indicative of poor stream health (percentages of hybrids, piscivores, diseased fish, and number of sunfish species) (p = 0.03). When watersheds of tributary streams are converted to impervious and non-row crop field LULC, they function biologically like the larger main stem river. Although fish and benthic macroinvertebrate metrics indicated the tributary and main stem Nolichucky sites were in relatively good condition, increases in land conversion can further degrade stream biotic integrity.
