Book excerpt: The conservation and protection of natural resources requires monitoring of temporal and spatial variability of ecosystem conditions, particularly with regard to human-induced stressors. The National Park Service (NPS) received a science mandate from Congress with the passing of the 1998 National Parks Omnibus Management Act and created the Inventory and Monitoring (I&M) Program. A primary role of the I&M Program is to collect, organize, and make available natural resource data and to contribute to the NPS's institutional knowledge by facilitating the transformation of data into information through analysis, synthesis, and modeling (NPS 2006a).

Available in PDF, EPUB and Kindle. Book excerpt: In 1992, macroinvertebrate sampling was initiated in Pools 4, 8, 13, 26, and the Open River reach of the Mississippi River, and La Grange Pool of the Illinois River as part of the Long Term Resource Monitoring Program Long-term monitoring is needed to detect population trends and local changes in aquatic ecosystems. Mayflies (Ephemeroptera), fingernail clams (Sphaeriidae), and the exotic Corbicula species were selected for monitoring. Midges (chironomidae) were added to the sampling design in 1993 and zebra mussels (Dreissena polymorpha) were added in 1995. Mayflies, fingernail clams, and midges, members of the soft-substrate community, were chosen because they play an important ecological role in the Upper Mississippi River System. Sampling was based on a stratified random design and was conducted at approximately 125 sites per study area. Mean densities of taxa were weighted by strata for extrapolation purposes.

Available in PDF, EPUB and Kindle. Book excerpt: The Biological Resource Evaluations Team of Los Alamos National Laboratories assessed the reliability of a gridded screen sub-sampling technique to estimate aquatic macroinvertebrates in total samples. Benthic macroinvertebrates were collected by kick sampling three riffles areas in Guaje Canyon, Los Alamos County, New Mexico during July and August, 1994. The study included 4,144 macroinvertebrates from samples consisting of 442 to 1005 individuals. The entire samples were spread onto a gridded screen, and 100 macroinvertebrates were randomly selected for identification. To simplify the results, identified macroinvertebrates were assigned to one of six categories: plecoptera, ephemeroptera, trichoptera, coleoptera, diptera, and non-insects. Three sub-samples were taken from each of six full samples. These counts were used as predicted values, while the total sample counts were used as actual values. Single-factor ANOVA tests showed no significant differences between predicted to actual (PTA) values. However, PTA differences indicated that lab-sorting was a more reliable method than live-sorting without a narcotizing agent. Large samples and large numbers in macroinvertebrate categories were tentatively linked with greater PTA differences. PTA differences were less than 5% in 80% of our trials and less than 10% in 95% of our trials. Despite the relatively small size of sub-samples, sub-samples included 60% of taxa found in the total samples. This sub-sampling technique provides accurate estimates of total sample composition in stream reaches rich enough to easily yield the required 100 individuals.

This book was released on 2013-08-03 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aquatic invertebrates are an important biological tool for understanding and detecting changes in stream ecosystem integrity, and can be used to reflect cumulative impacts that cannot otherwise be detected through traditional water quality monitoring. The National Park Service (NPS) began monitoring water quality and invertebrate community structure in Pratt Creek and a tributary (Winton Spring Branch) at Pea Ridge National Military Park (PERI) in 2009 (Bowles et al. 2008). An additional tributary of Pratt Creek (Lee Creek) was not included in the monitoring plan initially because it was thought to have intermittent flows during most of the year.
