This book was released on 2004 with total page 162 pages. Available in PDF, EPUB and Kindle. Book excerpt: Stream ecosystems are holistic systems that incorporate disturbances and abiotic influences at many spatial and temporal scales. This view supports a three-tiered model of variables that determine biotic integrity in streams, with causes and effects flowing from large-scale to fine-scale processes. Tier One characteristics include variables important at the scale of geomorphological processes and land use over entire watersheds. These variables largely determine Tier Two factors, abiotic conditions in a stream reach. Tier Two variables, in turn, largely structure the Tier Three variables, the stream's biotic communities. Through field studies and GIS analysis, relationships among these three tiers of variables were examined in this research to explore the question of how agriculture exerts its influence on stream fishes. This study investigated 27 streams, in two ecoregions and the transition area, or ecotone, between them, in south-central Ohio. The study design allowed questions to be asked concerning the relative influence of geomorphology and land use in varied landscapes, as well as relative impacts of watershed versus riparian land use. The region also contained relatively equal proportions of three types of agriculture (hay, row crops, and pasture) allowing the study to address the question of which land use might be most harmful to stream fish. This study supported the importance of row crop agriculture, finding it to be the most degrading type of agriculture for stream fish, but also found pasture to be an important causal factor in stream community degradation. This study also supported the importance of riparian buffers, finding riparian agriculture to be more degrading than agriculture over the entire watershed. A more interesting finding is the suggestion that a minor amount of nutrient enrichment from agricultural land use may benefit streams that are naturally oligotrophic. A possible mechanism could be increased primary production, which increases macroinvertebrate density, and provides a larger food base for fishes. This study also reports the possible existence of a biodiversity "hotspot" in the transitional region between the two ecoregions. Some evidence exists that greater habitat heterogeneity increases species richness, suggesting a possible cause for higher biodiversity in this ecotonal region. Since habitat heterogeneity over whole streams was not measured in this study, both the existence and mechanism of such a hotspot needs more study. A final conclusion is that geomorphology and agricultural land use may be equally important in structuring stream conditions, and thus, biological stream communities. This study illustrates the difficulties associated with overlapping causes and effects in complex systems such as streams and their catchments. Several variables in the study reported here required examination at multiple scales and with multiple statistical techniques in order to understand relationships that varied across different regions. The effects of a particular agricultural variable were not always equal in the diverse landscapes of southern Ohio. Lotic ecologists must examine a variety of ecoregions, and incorporate a variety of scales with a variety of analytic tools, if predictive stream ecology is to become a reality.

Book excerpt: Abstract: The use of multimetric biological indices (e.g., IBI, ICI, MIwB) to assess aquatic communities is well established in Ohio. These indices provide a definitive numeric assessment of the stream biotic communities to judge against established biocriteria in state water quality standards. However, these assessment tools cannot be applied to the smallest headwater streams of watersheds. The Ohio EPA recognizes three different types of primary headwater habitat streams (PHWH) that have watershed area 2.56 km2 and deep pools

This book was released on 2017 with total page 213 pages. Available in PDF, EPUB and Kindle. Book excerpt: Headwater streams comprise the majority of the stream network, providing important ecological functions to the downstream network. Although we are beginning to understand how network structure may influence fish, our understanding of how it influences benthic macroinvertebrate dispersal and population connectivity is limited. We also know little about how these patterns and processes may be disrupted as a result of human-driven landscape change such as stream barriers to movement and creation of artificial habitats such as stormwater and farm ponds. In this study, I investigated the effect of stream network position, stream size, and local habitat on benthic macroinvertebrates, and determined to what degree road crossings and impoundments may be degrading benthic macroinvertebrate and fish communities in headwater streams. These mechanisms were explored using Maryland Department of Natural Resources, (MDNR) Maryland Biological Stream Survey (MBSS) benthic macroinvertebrate, fish, and environmental data from first-order streams in the Piedmont region of Maryland. Using an Information Theoretic Approach (ITA), models were developed based on the hypothesized relationships between benthic macroinvertebrate and fish community structure and several network and anthropogenic impact variables. Based on my results, aquatic community structure was dependent on local habitat conditions and stream network structure. Both assemblages responded negatively to roads, which may suggest an isolation effect. These results also suggest that impoundments are acting as sources for benthic macroinvertebrates and fish, including non-native species.

This book was released on 2005 with total page 150 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: Processes at various spatial and temporal scales are known to affect lotic systems and the organisms that inhabit those systems. Because processes within watersheds are interactive across spatial scales, it is important to examine these processes at multiple scales. Additionally, multiple taxa studies are necessary in ecology because each group of taxa has a very different life-history and may react differently to various processes. Studies involving multiple taxa groups have been limited by the taxonomic specialization of many ecologists. Recent studies have examined the effects of single-scale processes on one or two groups of taxa or multiple-scale processes on a single group of taxa. However, multi-scale and taxa research has been neglected. In this study, I examined the effects of hierarchical landscape properties on aquatic macroinvertebrate assemblages in four first and second order streams in the Cuyahoga Valley National Park. Processes at sub-basin, reach, and microhabitat scales were studied to determine their influence on the macroinvertebrate assemblages. Sampled biota, in addition to macroinvertebrates, included salamanders and fishes: these biota were assessed in their relationship to the same hierarchy of habitat properties. Processes at each of the scales I examined had influence in structuring each group of taxa. Macroinvertebrate families are influenced most strongly by processes at the microhabitat and reach scales. Sub-basin and reach scale properties influenced salamander assemblages, and fishes were influenced more strongly by factors relating to stream size (both sub-basin and microhabitat). Stream size factors are determined mostly by watershed area, but underlying geology and hydrology also playa role. The presence of fish had no detectable effect on macroinvertebrate structures and a negligible effect on salamander assemblages.

This book was released on 2013 with total page 110 pages. Available in PDF, EPUB and Kindle. Book excerpt: Agricultural streams provide infrastructure for flood control and are periodically straightened and dredged to maintain their efficiency to drain farm land. These streams also serve as headwaters and may provide important spawning and refuge habitat for native fish. Twenty study sites were selected in Sandusky, Crawford and Seneca counties (Ohio) and sampled for habitat and fish community variables in June and September during each of four years (2008-2011). Sites had to (1) be surrounded by agricultural land, (2) likely hold water in the summer, (3) lack canopy cover, (4) represent varying times since last dip-out, and (5) have landowner permission for access. I included streams from both lake plain and morainal regions. Measures of stream morphology, time-since-last-dredging and selected habitat variables were correlated with fish community metrics such as abundance, richness, Simpson's Index, Shannon Diversity, and Index of Biotic Integrity. Fish communities were assessed using block seines in 50 m stream segments. Captured fish were identified to species, counted, assigned to an age class, inspected for gravidity and DELT, and released outside of the sampling segment downstream to prevent recapture. A total of 38,074 individual fish were sampled belonging to 35 species. Fathead minnow (10,068), creek chub (5,252), bluntnose minnow (4,737), central stoneroller (4,185), blacknose dace (3,942), blackstripe topminnow (3,803) and Johnny darter (1474) were most common and comprised 88% of the total fish catch. Non-native fish (wild goldfish, common carp, and mosquitofish) comprised only 0.1% of the total abundance. Adult fish data were combined into a June and September dataset to produce a more robust dataset and minimize pseudo replication. Channel morphology, expressed per site as the coefficient of variation of 11 wetted-stream width measurements (CoV-H) correlated weakly with year-since-last-dip-out (r=0.35, p=0.11) with a non-linear regression predicting only 14% of the variation. The coefficient of variation of 11 maximum water depth measurements (CoV-V) did not correlate with year-since-last-dip-out. Only IBI was significantly linked with CoV-V for the combined June and the combined September data (r=53, p=0.02; r=0.60, p=0.01, respectively). Using a non-parametric approach (Mann-Whitney), sites in morainal regions displayed a significantly higher CoV-V (z=3.08; p=0.002), whereas the difference in CoV-H approached significance (z=1.79; p=0.074). Lake plain and morainal sample sites did not differ in their year-since-last-dip-out (z=0.80; p=0.424) and IBI was the only fish community variable that was significantly higher in morainal streams than in lake plain sites for June and September (z=2.43; p=0.015 and z=2.28; 0.023, respectively). Cluster analysis did not produce obvious groupings based on physiography, location in the watershed or season of sampling. The fish community composition in each stream, however, is impacted by a multitude of biotic and abiotic factors that are difficult to separate. Agricultural streams provide habitat to a great number of fish and a substantial number of native species. Such environmental considerations should be considered in the management of these man-made streams.

This book was released on 2015 with total page 43 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ohio is a state dominated by agricultural land use. Such land use may directly alter stream waters and instream habitat, which may, in turn, affect fish communities. To examine the effects of agricultural land use on Ohio stream fish communities, I analyzed data compiled by the Ohio EPA, spanning 15 years and including 2,474 statewide sites. For 253 of these sites, I derived land use profiles from the 2011 USGS National Land Cover Database. While habitat quality was not correlated with agriculture, nutrient concentrations, alkalinity and total dissolved solids were positively correlated with agricultural land use within the catchment. Fish community integrity was negatively correlated with nutrient enrichment. Populations of Campostoma anomalum, a ubiquitous algae-grazing fish, were negatively impacted by nutrient enrichment as well. These results give further support to the body of work which shows that intensive agriculture negatively impacts streams and their biotic communities.

Available in PDF, EPUB and Kindle. Book excerpt: Conceptual separation of humans and natural ecosystems is reflected in the thinking of most natural resource management professions, including for estry, wildlife management, fisheries, range management, and watershed management (Burch 1971). Such thinking can deny the reality of the human element in local, regional, and global ecosystems (Bonnicksen and Lee 1982, Klausner 1971, Vayda 1977). As complex organisms with highly developed cultural abilities to modify their environment, humans directly or indirectly affect almost all terrestrial and aquatic ecosystems (Bennett 1976). Conse quently, information for managing watershed ecosystems is incomplete without consideration of human institutions and activities. Sociologists have studied the relationships between human societies and the land base or ecosystems on which they depend for over 60 years (Field and Burch 1990). These studies are distinguished by (1) a holistic perspec tive that sees people and their environments as interacting systems, (2) flex ible approaches that permit either the environment or human society to be treated as the independent variable in analyzing of society-environment re lations, and (3) accumulation of a substantial body of knowledge about how the future welfare of a society is influenced by its uses (or misuses) of land and water (Firey 1990).

Available in PDF, EPUB and Kindle. Book excerpt: The Clean Water Act (CWA) requires that wetlands be protected from degradation because of their important ecological functions including maintenance of high water quality and provision of fish and wildlife habitat. However, this protection generally does not encompass riparian areasâ€"the lands bordering rivers and lakesâ€"even though they often provide the same functions as wetlands. Growing recognition of the similarities in wetland and riparian area functioning and the differences in their legal protection led the NRC in 1999 to undertake a study of riparian areas, which has culminated in Riparian Areas: Functioning and Strategies for Management. The report is intended to heighten awareness of riparian areas commensurate with their ecological and societal values. The primary conclusion is that, because riparian areas perform a disproportionate number of biological and physical functions on a unit area basis, restoration of riparian functions along America's waterbodies should be a national goal.
