Freshwater Pearl Mussel (margaritifera Margaritifera) Host Choice and Behavioural Responses to Changes in Flow Regime
The endangered freshwater pearl mussel (Margaritifera margaritifera), one of the longest-lived invertebrates, are threatened globally. Scotland, UK, remains a stronghold, however even here the population is declining due to factors such as habitat degradation, pollution and pearl fishing. The study comprised two parts: field surveys of glochidia infection of host salmonid fish, and a novel labo...
متن کاملSeasonal changes in the behaviour and respiration physiology of the freshwater duck mussel, Anodonta anatina.
For low-energy organisms such as bivalves, the costs of thermal compensation of biological rates (synonymous with acclimation or acclimatization) may be higher than the benefits. We therefore conducted two experiments to examine the effect of seasonal temperature changes on behaviour and oxygen consumption. In the first experiment, we examined the effects of seasonal temperature changes on the ...
متن کاملAsymmetric dispersal structures a riverine metapopulation of the freshwater pearl mussel Margaritifera laevis
Unidirectional water flow results in the downstream-biased, asymmetric dispersal of many riverine organisms. However, little is known of how asymmetric dispersal influences riverine population structure and dynamics, limiting our ability to properly manage riverine organisms. A metapopulation of the freshwater pearl mussel Margaritifera laevis may be sensitive to river currents because mussels ...
متن کاملOntogeny of juvenile freshwater pearl mussels, Margaritifera margaritifera (Bivalvia: Margaritiferidae)
The gills of juvenile freshwater bivalves undergo a complex morphogenesis that may correlate with changes in feeding ecology, but ontogenic studies on juvenile mussels are rare. Scanning electron microscopy was used to examine the ultrastructure and ontogeny of 117 juvenile freshwater pearl mussels (Margaritifera margaritifera) ranging in age from 1-44 months and length from 0.49-8.90 mm. Three...
متن کاملCell renewal in the gill of the freshwater mussel, Margaritifera margaritifera: an autoradiographic study using high specific activity tritiated thymidine.
High specific activity tritiated thymidine (50-3 Ci/mM and 56 Ci/mM) and autoradiographic techniques were used to study cell renewal in the gill epithelium of the freshwater mussel, Margaritifera margaritifera. The cell renewal system in the gill epithelium of M. margaritifera appears to consist of a stem-type population in the gill furrow and gill furrow edges which supplies, through division,...
