This book was released on 2021 with total page 146 pages. Available in PDF, EPUB and Kindle. Book excerpt: Southern Green Bay, Lake Michigan is one of the most productive ecosystems in the Great Lakes and has historically been subjected to a wide range of stressors, yet little is known about the current macroinvertebrate community structure. The most recent comprehensive assessment of benthic fauna was by Markert (1982) in 1978. The objectives of this project were to describe the current macroinvertebrate community, examine changes since 1978, and identify major environmental drivers of benthic community compositions. In total, 258 stations were surveyed, including 97 that were also sampled in 1978, 100 that were added to increase spatial resolution, and 61 that were subjected to periodic hypoxia. I collected 95 macroinvertebrate taxa in southern Green Bay with the community dominated by the eurytopic midge Chironomus and immature tubificid worms. Nonmetric multidimensional scaling (NMDS) ordination and indicator analyses distinguished contemporary and historical communities and revealed shifts in benthic macroinvertebrate structure; although oligochaete worms and chironomids remained dominant over time, Chironomus abundance increased and characterized the contemporary community, whereas the benthos were historically more diverse. The magnitude of temporal change varied regionally with larger differences concentrated in southern middle bay and the inner bay remaining comparable to 1978. Contemporary assemblages are driven primarily by productivity, substrate type, and hypoxia, according to NMDS ordinations. Regular benthic monitoring should continue to evaluate biological responses to environmental stressors and assess management actions.

This book was released on 2015 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The monitoring of changes in benthic macroinvertebrate communities over time facilitates the evaluation of changes in the function and structure of aquatic ecosystems. I hypothesize that it will be possible to reconstruct historic macroinvertebrate communities by examining gut contents of fishes preserved in natural history museums. Researchers can use this knowledge to estimate the historic benthic macroinvertebrate community for streams from which we have fish museum specimens. These historic data can then be compared to current data to see how macroinvertebrate communities have changed over time.In this study, the fishes whose gut content most accurately reflected the benthic macroinvertebrate community of a freshwater stream, specifically Marshalls Creek, were identified. Both fish species and benthic macroinvertebrates were collected at various sites of Marshalls Creek in East Stroudsburg, PA, in March, August, and December 2010. Collections were taken at different times of year to reflect seasonal variation both in species sampled and quantity collected. 231 fish were dissected and their gut contents identified. Bluespotted Sunfish, Redbreast Sunfish, and White Suckers were the species that best represented the benthic macroinvertebrate community from their gut content. These species can be used to predict 81% of the total summer taxa.If there are 10 museum specimens of the selected species available, (in this case 10 White Suckers, 10 Bluespotted Sunfish, and 10 Redbreast Sunfish), one could dissect a total of 30 fish and expect to identify 68% of the total taxa (both kicknet and gut taxa combined) found in the freshwater stream where the specimens originated.In order to estimate sampling distribution, using R 3.0.2, 100 simulations were run of each combination of three fish species to determine the average quantity of taxa consumed (to the family level) along with sampling variation. The benthic macroinvertebrate data obtained fromivthe dissection of museum specimens could then be compared to data obtained from more recently collected specimens (10 White Suckers, 10 Bluespotted Sunfish, and 10 Redbreast Sunfish) and a comparison made to determine how the macroinvertebrate community has changed over time. Are families associated with high quality streams missing from the current collection? Based on which macroinvertebrate families are present and/or absent, the types of stresses that have caused these absences can be determined.
