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 2012 with total page 108 pages. Available in PDF, EPUB and Kindle. Book excerpt: Macroinvertebrates constitute the backbone of megafaunal communities in benthic ecosystems around the globe. Many macroinvertebrates have vital roles in benthic ecosystems, ranging from enhancing habitat complexity to providing staple food sources for other organisms. Regardless of how familiar macroinvertebrates are to the general public, very few studies have attempted to describe benthic macroinvertebrate assemblages across large spatial scale in the continental shelf waters of the Pacific Northwest. This study describes different subtidal macroinvertebrate assemblages off Washington and Oregon based on species-substrata associations and the key species that distinguish one assemblage from another. Two data sets were used for this study: underwater footage collected by the submersible Delta during 1993-1995 geological surveys, and footage collected by the remotely operated vehicle (ROV) Hammerhead during macroinvertebrate surveys in late summer 2011. Footages from these surveys were used to document species-substrata associations and distinguish different assemblages based on species composition similarities and dissimilarities. In addition, I determined if a specific group of invertebrates, Asteroids (Echinodermata), were useful in explaining different assemblage patterns, after all other environmental parameters were taken into account. Findings of this study can be used not only to shed light on the structure of macroinvertebrate communities in the Pacific Northwest, but also as baseline data for future research on the direct and indirect effects of potential offshore installations on macroinvertebrate communities across the continental shelf waters.

Book Synopsis Some Changes in the Bottom Fauna of Green Bay, Lake Michigan from 1952 to 1969 by : Richard Howmiller
Download or read book Some Changes in the Bottom Fauna of Green Bay, Lake Michigan from 1952 to 1969 written by Richard Howmiller and published by . This book was released on 1971 with total page 58 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bottom samples were collected in lower and middle Green Bay in May 1969 on the same date, at the same 27 stations, and using the same methods as a 1952 survey. In 1969 there were fewer Oligochaeta and Chironomidae in the vicinity of the Fox River mouth. Elsewhere in the lower and middle bay oligochaetes and midge larvae were more abundant than in 1952 but most other benthic invertebrates were less abundant. The observed changes are interpreted as indicative of greater pollution and increased eutrophication during the intervening 17 years.
