Available in PDF, EPUB and Kindle. Book excerpt: The increasing popularity of benthic macroinvertebrate use for biological monitoring and assessment of lotic systems calls for new applications for regions with a lesser known fauna and an overall better understanding of how community measures are influenced by seasonal variability. Two separate studies are presented to address aspects of biological monitoring that are seldom studied. The first study focused on evaluation of Grass Riparian Filter Strip effectiveness in north central Missouri. Streams within conservation areas and unprotected reaches were sampled to identify metrics that could distinguish between undesired and best attainable conditions. These metrics were used to construct two assessment tools, a Benthic Index of Biotic Integrity (B-IBI) and a novel technique we call a Least Desired Index (LDI). LDI works in a reciprocal fashion to B-IBI in that the lowest scoring criteria of the metrics are set by anti-reference stream conditions, or conditions that represent an undesirable quality. B-IBIs were developed from the conservation stream samples and the LDI was developed from the unprotected stream reaches. Two test sites with established GRFS were sampled and assessed with the B-IBI and the LDI. B-IBI determined that the GRFS sites showed moderate improvements where the LDI showed that the GRFS sites made no improvements. The LDI was considered to be a more realistic assessment considering that the GRFS at the test sites had only been established for 2 years and the reference streams used to construct the B-IBI were most likely impaired. The second study utilized a state designated reference stream as a case study for temporally profiling the community structure. Samples of benthic macroinvertebrates and water quality were taken approximately monthly to fulfill four objectives. The first objective was to determine if a temporal profile of the community might better reveal members of the community that are rare and transient. The second objective was to consider the maturity of each individual in weighting abundances and how these might affect the interpretation of the community structure. The third objective examined annual variability of 120 metrics. Multiple regressions with physico-chemico-temporal variables were created to see if these metrics could be predicted for samples taken during the following year. The last objective was to construct a River Invertebrate Prediction and Classification System (RIVPACS) model that classified seasons based on the biota and to use this model to predict and compare the community composition of samples taken during the following year. Rare and two types of transient taxa were recognized. Rare taxa were considered to be residents of the community, but infrequently encountered. Transient type I taxa were considered adventitious, and transient type II were short lived. Maturity weighted abundances showed significant changes in community measures and were found to be useful in aspects of other analyses. Few metrics exhibited low variation over the annual period, and fewer were predictable, indicating that seasonal variation can have a significant impact on measurements used in biological monitoring. The RIVPACS model biologically classified three seasons. Overall, the model moderately predicted community structure, also highlighting that macroinvertebrate communities are difficult to consistently quantify. Lotic habitats are important resources but are dynamic systems exhibiting challenging perspectives with regard to monitoring and quality assessment.

Book excerpt: Tallgrass prairie streams and their fauna are understudied, due in part to their rarity. The composition of prairie stream communities differs geographically due to regionally and locally determined environmental characteristics and varies over time due to disturbance events. This research focused on expanding the current knowledge of temporal and spatial variation in the macroinvertebrate communities of Missouri prairie streams. Intra-seasonal variation in the macroinvertebrate community of one prairie stream was correlated with changes in the stream environment and resulted in three relatively short-lived but significant community groupings. These intra-seasonal community shifts also affected functional feeding group structure and led to significant differences in biomonitoring measures over the course of weeks. For situations in which small, dynamic stream systems need to be monitored, sampling should be conducted at frequent intervals to capture changes in communities that may occur within seasons. The regional diversity and community structure of prairie headwater stream communities is in part driven by both the intermittent nature and the relative scarcity of prairie stream habitat. The macroinvertebrate communities of the headwater networks from five prairies in Missouri were unique. Differences in their taxonomic composition led to differences in biomonitoring metric values. The distinct community compositions of the headwater prairie streams studied and the high regional diversity documented are likely driven by geographic isolation rather than local environmental factors. Each of these prairie stream systems is an important contributor to species diversity at a regional level. Conservation and restoration efforts must work to preserve the biotic diversity in prairie streams to support existing macroinvertebrate communities that remain. For lotic insects to maintain stable populations across fragmented prairie patches and their intermittent streams in Missouri, dispersal must occur between patches to enable recolonization of streams after disturbance. Leptophlebia konza Burian was thought to be restricted to its type locality of Konza Prairie, Kansas; however, a population was discovered at Hi Lonesome Prairie in Missouri during an extensive search of 54 prairies. DNA sequence data from cytochrome oxidase subunit 1, CO1, show that both populations of L. konza lost genetic diversity during a recent bottleneck, either because of habitat fragmentation or competition from other species, including Leptophlebia johnsoni McDunnough. The rarity of L. konza populations across Missouri when taken into consideration with DNA sequence data suggest that L. konza populations are unstable and unable to disperse between remaining prairie patches. Water quality monitoring and research activities taking place in prairie streams must take into account spatial and temporal variation in both community structure and genetic diversity across these landscapes.

Download or read book Pond Conservation in Europe written by Beat Oertli and published by Springer Science & Business Media. This book was released on 2010-09-24 with total page 372 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ponds are an exceptional freshwater resource around the world and represent thirty percent of the global surface area of standing water. Furthermore, the millions of ponds which exist exhibit a particularly high biodiversity and have a high potential for ecosystem functions and services. Despite these impressive features, ponds face many threats from a variety of human activities and receive little or no protection under European and national legislation. Consequently, there is an urgent need to protect, consolidate and increase the pond resource in Europe. In order to achieve these objectives, the European Pond Conservation Network (EPCN) was launched 2004 in Geneva. Its aim is to promote the awareness, understanding and conservation of these small water bodies in the European landscape. This volume of “Developments in Hydrobiology” presents a selection of 31 papers presented during EPCN conferences held in 2006 in France (Toulouse) and in 2008 in Spain (Valencia). They represent a diverse collection of themes from across the continent and North Africa and present new and original insights into topics as wide ranging as pond biodiversity; human disturbance; landscape ecology; ecological assessment and monitoring; practical management measures; ecological restoration; hydrology and climate change; invasive species and threatened species.
