Book excerpt: During the past three years, weve made significant strides toward documenting distributions and understanding Montanas freshwater mussels through data compilation, inventory and public education. Although the five eastern Montana mussel species (2 native and 3 introduced) have secure populations and are even expanding their ranges, one of the states native species, the western pearlshell, Margaritifera falcata has experienced significant range reductions in the past 100 years, and in 2008 was added to Montanas SOC list as a S2, vulnerable to extinction in the state. Despite finding eight western streams with large viable pearlshell populations (up to 3,000 mussels per km), we have evidence from hundreds of negative surveys documenting the extirpation of the western pearlshell from countless streams and hundreds of river miles throughout the state, as well as dozens of non-viable populations that will be extirpated from streams and whole watersheds (Smith River) within the next 25 years. This fact should be an impetus to continue to research and understand this species in Montana, in addition to actively pursuing restoration projects that would benefit this species or its native fish host the westslope cutthroat trout. We performed extensive surveys in most of the eastern watersheds of the state and report that the largest populations of warm water mussels, notably the native fatmucket and introduced black sandshell (avg. 8.2 and 4 mussels per hour, respectively), are found within the Wild & Scenic Missouri River between Fort Benton and Judith River landing and the Marias River (above Lake Elwell & within 10 miles of the confluence) where fatmucket populations are approaching Missouri River densities (avg. 7 per hr). The native giant floater, Pyganodon grandis is more evenly distributed and abundant in the Northern Glaciated Prairie River Basins compared to central and southeast Montana, but rarely did we find populations exceeding more than 10 mussels per hour. Our surveys in the Yellowstone River indicate that the mainstem river has much lower mussel density overall, with fatmucket catch rates averaging ~1 per hour. Although, large prairie rivers entering the Yellowstone River have higher fatmucket densities: Bighorn and Tongue Rivers averaged 6 and 5 individuals per hour, respectively. We documented the first records of live giant floaters in the Yellowstone Basin at 3 tributary sites (OFallon, Little Porcupine, Tongue River), but no evidence of this species found live in the mainstem. The introduced mapleleaf (Quadrula quadrula) has high densities in the lower Tongue River, but was not found live in the mainstem Yellowstone. The introduced creek heelsplitter have increased their upstream distribution in the Milk River system, but not to the extent that the black sandshell have expanded their range. The introduced mussels in Montana do not seem to be negatively affecting the native species, coexistence and non-exclusion is evident in stream reaches documented to have both present. But rather, they seem to be an augmentation to the mussel fauna of the state and in the case of the black sandshell seems to be more viable in the upper Missouri River than in its native sections of the Missouri River where it is in decline. Over the last three years weve given mussel survey and identification workshops to over 65 fisheries biologists and hydrologists in MT & ID to increase the knowledge base, interest and capacity to survey and report mussel populations in all regions of the state. Attendees of these workshops reported back data for an additional 100 survey reaches, including the identification of two new viable western pearlshell sites in 2009. To generate public interest and support of freshwater mussels, we produced a pocket-sized mussel field guide and a full-sized Mussels of Montana Poster which will be distributed around the state from various agency offices and within the science educational system. Increasing interest and knowledge in freshwater mussels and species other than the typical sportfish is essential for the sustainability of these species and for the concern of the health of their aquatic ecosystems.

Download or read book Freshwater Mussel Ecology written by David L. Strayer and published by Univ of California Press. This book was released on 2008-06-10 with total page 217 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pearly mussels (Unionoidea) live in lakes, rivers, and streams around the world. These bivalves play important roles in freshwater ecosystems and were once both culturally and economically valuable as sources of food, pearls, and mother-of-pearl. Today, however, hundreds of species of these mussels are extinct or endangered. David L. Strayer provides a critical synthesis of the factors that control the distribution and abundance of pearly mussels. Using empirical analyses and models, he assesses the effects of dispersal, habitat quality, availability of fish hosts, adequate food, predators, and parasites. He also addresses conservation issues that apply to other inhabitants of fresh waters around the globe and other pressing issues in contemporary ecology.
Download or read book Zebra Mussels Biology Impacts and Control written by Thomas F. Nalepa and published by CRC Press. This book was released on 1992-11-24 with total page 848 pages. Available in PDF, EPUB and Kindle. Book excerpt: The introduction and rapid spread of the zebra mussel in North American waters has caused great concern among industrial and recreational users of these waters. This bivalve mollusk is a biofouler that attaches to any firm substrate (e.g. rocks, piers, water intake pipes, boat hulls) and has already created significant problems for raw water users such as water treatment plants and power plants. Zebra Mussels: Biology, Impacts and Control provides essential information regarding the biology of the zebra mussel in North America and Europe, presents case studies of environmental and industrial impacts, and outlines control strategies. Summary articles detail its life history, origins, and morphology. The book also examines techniques used to culture and maintain this organism in the laboratory. Thirty-two color plates illustrate some of the dramatic problems created by the explosive population growth of this species. Zebra Mussels: Biology, Impacts, and Control is an important resource for ecologists, conservationists, environmental consultants, water quality engineers, regulatory officials, power utilities, and libraries.

Book excerpt: Abbie Gascho Landis brings readers to a hotbed of mussel diversity, the American Southeast, to seek mussels where they eat, procreate, and, too often, perish. Accompanied often by her husband, a mussel scientist, and her young children, she learned to see mussels on the creekbed, to tell a spectaclecase from a pigtoe, and to worry what vanishing mussels--70 percent of North American species are imperiled--will mean for humans and wildlife alike. Landis shares this journey, traveling from perilous river surveys to dry streambeds and into laboratories where endangered mussels are raised one precious life at a time. Mussels have much to teach us about the health of our watersheds if we step into the creek and take a closer look at their lives. In the tradition of writers like Terry Tempest Williams and Sy Montgomery, Landis gracefully chronicles these untold stories with a veterinarian's careful eye and the curiosity of a naturalist.--

Download or read book Ecology and Evolution of the Freshwater Mussels Unionoida written by G. Bauer and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 400 pages. Available in PDF, EPUB and Kindle. Book excerpt: All those who think that bivalves are boring are in the best company. Karl von Frisch is reported to have turned the pages more quickly in texts where bivalves were treated because, according to him, they literally lack any behaviour. The fact that they can filtrate huge amounts of water, burrow into the sedi ment, actively swim, drill holes into rocks and boats or detect shadows with the aid of pretty blue eyes located on the rim of their mantle obviously left v. Frisch unimpressed. Why, then, a book on the large freshwater mussels (Naiads or Unionoida), which on first sight are much less spectacular than the marine ones? The main reason is that they are keepers of secrets which they reveal only on close and careful inspection. This is not only true for the pearls some species produce and which over centuries have contributed to the treasures of bishops and kings, but particularly for their ecology: their life cycles are linked with those of fishes, some can occur in incredible densities and some can live for more than 100 years. Thus, the presence or absence of naiads in a lake or stream has manifold implications.
