Sampling adequacy of freshwater mussel surveys and variation of mussel species richness in Illinois wadeable streams
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 …

DYNAMICS OF A SUBMERSIBLE MUSSEL RAFT
The dynamics of a submersible mussel raft were analyzed using wave tank testing, numerical modeling, and full-scale field tests. When submerged, the raft’s pontoons are flooded, and it is held vertically by lines attached to surface floats and horizontally by a spread mooring. This submerged …

Factors affecting the infauna associated with mussel beds
… (tidal height, wave exposure, biogeography, mussel species and mussel size) have on the community composition of the infauna associated with mussel beds along the coast southern Africa.

Ecophysiology of the black mussel Choromytilus meridionalis (Krauss)
… respiration and assimilation of the black mussel Choromytilus meridionalis (Kr.) at Bailey's Cottage, False Bay, South Africa. The reproductive season and gonad development is described from monthly measurements made over a period of 4 years. Spawning usually extends from July to February …

Tropic interactions within South African intertidal mussel beds
Community structure of intertidal rocky shore mussel beds has been previously shown to be strongly influenced by trophic interactions, particularly interactions between predators of mussels and their prey. This investigation involved, firstly, construction of models to simulate trophic interactions …

UNDERWATER BONDING WITH POLYMER MIMICS OF MUSSEL ADHESIVE PROTEINS
… adhesion, shellfish are the true experts. Mussels, barnacles, and oysters attach to rocks with apparent ease. Yet our man-made glues often fail miserably when trying to stick in wet environments. Results described herein focus on poly[(3,4-dihydroxystyrene)-co-styrene], a polymer mimic of …

Population structure and recruitment patterns of the indigenous Mussel Perna perna and the Alien Mussel Mytilus galloprovincialis on the central coast of Namibia
… has been well documented for the Mediterranean mussel Mytilus galloprovincialis throughout the world. This study assessed the spatial and temporal variation of population structure, recruitment patterns, condition index and abundance of the indigenous mussel Perna perna and alien mussel M. …

Dispersal and remineralisation of biodeposits: Ecosystem impacts of mussel aquaculture
… of nearshore ecosystems. In New Zealand the mussel Perna canaliculus has a high natural abundance and is also intensively cultured. This thesis examines the dispersal and remineralisation characteristics of mussel P. canaliculus biodeposits and the impacts of sedimentation from a mussel farm …

Reproductive ecology of the California sea mussel, Mytilus californianus Conrad
… Mytilus californianus is the common mussel found along the more exposed west coast of North America from the Aleutian Islands south Isla Socorro, Mexico (Soot-Ryen, 1955) and was chosen because it is an important species in rocky intertidal communities (being the most abundant if not …

Host Fish Assessment and Gravidity for the Mussel Elliptoideus sloatianus
… sloatianus (purple bankclimber) is a freshwater mussel that m endemic to the Apalachicola River Basin, which includes the Chattahoochee, Flint, Chipola, and Apalachicola Rivers. Populations of E. sloatianus also exist in the Ochlockonee River, which discharges independently from the ACF basin …

Mechanics of the hysteretic large strain behavior of mussel byssus threads
… widely-used synthetics. This study investigates mussel byssal threads, the attachment appendage of aquatic mussels, which are here shown to exhibit a remarkable ability to withstand very large resilient yet dissipative stretches (A > 4) without failing. These threads were dissected into separate …

Using surface topography to re-analyze gradients in mussel byssal threads
… gradient in the collagenous core fiber of mussel byssal threads. Mussel byssal threads have a natural, stiff, thin outer coating that is chemically and mechanically distinct from the softer collagenous core making them a prime subject for wrinkling analysis. Past work in the area has …

A Holistic Approach to Taxonomic Evaluation of Two Closely Related Endangered Freshwater Mussel Species, the Oyster Mussel (Epioblasma capsaeformis) and Tan Riffleshell (Epioblasma florentina walkeri) (Bivalvia: Unionidae)
… and characterized for the endangered oyster mussel Epioblasma capsaeformis from the Clinch River, TN. Microsatellite loci also were amplified for individuals collected from the following additional populations or species: (1) E. capsaeformis from Duck River, TN; (2) E. florentina walkeri from …

DOES FAT MATTER? Lipidomics investigations during Blue mussel (Mytilus sp.) hatchery production
The blue mussels (Mytilus sp) are an economically important species for European aquaculture, accounting, by weight, for over 50% of the bivalves produced across Europe. Nevertheless, the European mussel production sector is experiencing a continuous decline, with a net decrease in the production …

Uptake and depuration of cyanotoxins in the common blue mussel Mytilus edulis.
… and depuration of cyanotoxins in the common blue mussel Mytilus edulis, three feeding trials were performed. During these, mussels were exposed to two cyanobacteria strains - Nodularia spumigena KAC66 and Microcystis aeruginosa PCC 7813 - both individually and simultaneously. A rapid …

Reproductive Biology of the Flat Floater Mussel, Anodonta Suborbiculata, Say, 1831 (Mollusca: Unionidae)
The flat floater mussel, Anodonta suborbiculata , is a large, distinctive freshwater bivalve that formerly occurred in shallow lentic habitats throughout the Mississippi River Drainage. The flat floater is presently rare due to habitat loss. Several aspects of the reproductive biology of this …

Circadian and Circatidal Rhythms of Protein Abundance in the Intertidal Mussel Mytilus californianus
… At the cellular level, transcriptomic studies on mussels’ baseline circadian and circatidal rhythms have determined that the circadian rhythm is the dominant transcriptional rhythm. However, as proteins reflect the basic molecular phenotype of an organism and their abundance may differ greatly …
