This book was released on 2017 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Freshwater mussels continue to be one of the most imperiled groups of animals in North America. Management actions for many mussel species today are critical and might have lasting impacts on preventing local, regional, and perhaps even global extinctions. Citizen scientists can play an important role in gathering field data for informed conservation strategies, which are more important today than ever before. This project aims to develop an inexpensive sampling protocol for freshwater mussels that is teachable and effective for engaging citizen scientists. We developed and tested a rapid assessment survey design based on 10 m x 1 m transects. Results describe mussel community structure and microhabitat associations at 32 sites within five watersheds of the Green Bay Hydrological Basin in northeastern Wisconsin, USA. To gauge the effectiveness of the rapid assessment design, we re-surveyed six productive sites, two within the Oconto River, Pensaukee River, and Duck Creek, using the more intensive Wisconsin Department of Natural Resources (WDNR) standard sampling protocol. This method evaluates mussels in 5 m x 5 m grids sub-sampled in smaller 0.25 m x 0.25 m quadrats. Habitat variables were measured at each transect and grid area to explore the effects of watershed and habitat-level factors on the presence of freshwater mussels. Overall, 4,205 records from 20 mussel species were recorded. Observed richness and abundance varied significantly among these sites; highest numbers of mussels were recorded at the Oconto River, whereas no living mussels were present at any sites within the Little Suamico River. The average time among all watersheds to conduct individual surveys was significantly faster (P

Available in PDF, EPUB and Kindle. Book excerpt: The objective of this guide is to help field biologists conduct better surveys of freshwater mussel populations. It opens with a discussion of several considerations and a question that should direct the design of any study of mussel populations. The authors then present sampling designs and methods that may be useful to mussel biologists. The also discuss examples of study designs that address several common objectives of studies of mussel populations.

This book was released on 2011 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Freshwater mussels are one of the most imperiled groups of animals in North America. Effective conservation strategies and resource management of freshwater mussels require adequately characterizing local mussel assemblages. However, sampling protocols for mussel surveys, including sampling efforts, have not been well established and tested. Furthermore, the percentage of all species captured with a standard sampling effort (e.g., search of man-hours) may vary greatly among sites, introducing biases into our understanding of species-diversity patterns and temporal trends. In addressing both questions, I focused on time-based search, one commonly used sampling technique in stream mussel surveys in the present study. I sampled 18 wadeable-stream sites mainly in east-central Illinois, selected based on watershed size, dominant-substrate type, and historic species diversity. With 16 man-hour search per site, my sampling crew collected 27-942 individuals and 5-18 species per site. I estimated the total species richness at a site with Chao-1 method that accounted for imperfect species detectability. I measured sampling adequacy at a given effort as the % of all estimated species recorded. A frequently used effort, 4 man-hour search, captured 15-100% of all species with an average of 61%. Observed species richness was not significantly correlated with the estimated total richness until sampling effort reached 8 man-hours (Pearson0́9s r = 0.59, p

This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Under the Species at Risk Act, Fisheries and Oceans Canada is responsible for the management of aquatic species at risk including freshwater mussels. Adaptive and responsive species management requires robust survey methods to answer management questions. To date, most of the survey method guidelines to monitor freshwater mussels in Canada have been developed for wadeable streams. However, there is a need to develop deep-water survey guidelines and protocols to ensure adequate protection for mussel species found in deep, turbid environments. This report summarizes the results from a literature review of freshwater mussel (Bivalvia: Unionidae) sampling methods and techniques used in deep, turbid, or high-flow environments. In total, 110 sources from primary and grey literature were reviewed"--Abstract, page iv.

This book was released on 2018 with total page 139 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Cumberland and Tennessee River drainages harbor high diversity and endemism of freshwater mussels. The faunas of the Harpeth River drainage and Duck River tributaries have been disproportionally understudied relative to other Cumberlandian streams. Forty-two sites on 23 tributaries in the Harpeth River drainage and a 21-kilometer reach of the main channel were assessed qualitatively for freshwater mussels. Relic shells of four species were observed in eight sites on four of the tributaries. Twenty species were observed in the main channel including the discovery of a new Harpeth River drainage record: Simsponaias ambigua. Catch per unit effort (CPUE) ranged from 0.0 to 32.0 mussels/h. Lampsilis fasciola and Potamilus alatus were the most abundant species. Mussel populations were fragmented and all species exhibited primarily large size-classes. Eighty-three sites on 37 tributaries in the upper and middle Duck River drainage were sampled qualitatively. Nineteen species were observed and 12 were collected live or fresh dead, and CPUE ranged from 0.0 to 58.0 mussels/h. Villosa vanuxemensis and Villosa taeniata were the most abundant and widespread species observed. Live mussels were found in only five tributaries, although mussels historically occurred in 17 of the sampled streams. Length frequency analysis indicated recent recruitment for four species in Big Rock Creek. Results of canonical correspondence analysis for both drainages revealed no association between environmental variables and mussel community structure (live and fresh dead individuals combined), likely a result of low densities. Two sites on Big Rock Creek in the Duck River drainage were sampled quantitatively using 0.25-m2 quadrats. Densities were 0.33 and 1.27 mussels/0.25m2 and species richness ranged from four to five. Quantitative sampling indicated that qualitative timed searches may be sufficient for detecting recruitment in small streams. Anthropogenic alteration has resulted in extensive loss of freshwater mussel habitat, leading to local extirpations and a reduction of diversity and abundance in both watersheds.
