Ontogeny 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 کاملDuration of the parasitic phase determines subsequent performance in juvenile freshwater pearl mussels (Margaritifera margaritifera)
Host-parasite systems have been useful in understanding coevolutionary patterns in sympatric species. Based on the exceptional interaction of the long-lived and highly host-specific freshwater pearl mussel (FPM; Margaritifera margaritifera) with its much shorter-lived host fish (Salmo trutta or Salmo salar), we tested the hypotheses that a longer duration of the parasitic phase increases fitnes...
متن کاملFreshwater 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 کاملReintroduction of captive-bred animals
The Hustain Nuru region of Mongolia’s Chentai Mountains is one of the country’s most pristine wild areas. Valleys and slopes harbour steppe vegetation such as fescue, brome grass and feathergrasses, while birch woods grow in the upper elevations of this relatively low lying mountainous region. A diverse range of wild fauna including marmots, lemmings, red deer, wild sheep, polecats, Pallas cat,...
متن کاملPearl mussels (Margaritifera marocana) in Morocco: Conservation status of the rarest bivalve in African fresh waters.
Margaritifera marocana is one of the rarest freshwater mussel species (listed as critically endangered), and is endemic to Morocco. Despite its constrained distribution and low abundance, to date there are no quantitative studies addressing the conservation status of this species. Surveys were conducted in 36 sites along the Oum Er Rbia river basin (Rivers Derna, Laabid and Oum Er Rbia) to asse...
