Chloride Transport in Freshwater Mussels

Physiological Zoology, 1979
Chloride transport in unionid bivalves is cation independent and is apparently an anion exchange system. The influx of Cl is highly correlated with the appearance of titratable base in the bathing medium. There is a substantial exchange diffusion component of Cl fluxes in these mussels.

Glochidial Mortality in Freshwater Mussels

2001
A crucial factor in the reproduction of parasites is the rate of successful host infection. In most parasitic species subtle mechanisms for the effective transmission of infectious stages have evolved. These include vector transmission, highly mobile propagules that are able to locate and infect new hosts actively, attraction of hosts, extremely ...

The Freshwater Mussels of Tennessee

1998
With more than 150 species and subspecies recorded in the state, Tennessee has one of the most diverse freshwater mussel faunas in North America. Valuable as indicators of water quality, these mollusks have themselves become threatened as development encroaches on habitat—twenty-three are currently listed as endangered species and at least twelve have ...

Thiaminase activity in native freshwater mussels

Journal of Great Lakes Research, 2015
Abstract Thiamine (vitamin B 1 ) deficiency in the Great Lakes has been attributed to elevated levels of thiaminase I enzyme activity in invasive prey species; however, few studies have investigated thiaminase activity in native prey species. Some of the highest levels of thiaminase activity have been measured in invasive dreissenid mussels with ...

Allocation policy of female freshwater pearl mussels

Oecologia, 1998
Living exclusively in trout streams which are very poor in nutrients, freshwater pearl mussels are physiologically adapted to the low food supply by a reduced metabolism. Longevity of these mussels spans decades and life-time fecundity of females is very high (up to 2*108 larvae).

Global diversity of freshwater mussels (Mollusca, Bivalvia) in freshwater

Hydrobiologia, 2007
The term freshwater bivalve is very inclusive and not very informative. There are representatives of at least 19 families that have at least one representative living in freshwater. This suggests at least 14 different invasions of freshwater. At least nine families have small to large radiations in the freshwater environment: Corbiculidae, Sphaeriidae,

Manganese profiles in freshwater mussel shells

Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, 2001
The heavy ion microprobe in combinatio with particle-induced X ray emmission was used to measured the distribution of manganese in freshwater mussel shells (Hyridella depressa) from the Nepean river in south-eastern Australia. Close to the ventral edge, bands with an elevated menganese content have been detected.

Does electrofishing harm freshwater pearl mussels?

Aquatic Conservation: Marine and Freshwater Ecosystems, 2001
Abstract1. Two experiments were carried out in a Scottish river to test the effects of electrofishing on endangered freshwater pearl mussels (Margaritifera margaritifera).2. In the first experiment, two areas of mussel bed were marked out as treatment and control sites and the former was electrofished using standard equipment. The mussels were examined
