The effect of seasonal temperature variation on behaviour and metabolism in the freshwater mussel (Unio tumidus).
Temperature plays a critical role in determining the biology of ectotherms. Many animals have evolved mechanisms that allow them to compensate biological rates, i.e. adjust biological rates to overcome thermodynamic effects. For low energy-organisms, such as bivalves, the costs of thermal compensation may be greater than the benefits, and thus prohibitive. To examine this, two experiments were ...
متن کاملEffect of Salinity on the Growth and Survival of the Freshwater Mussel, Unio crassus, in an Environmentally Disturbed River
The aim of this study was to examine the effects of salinity on the survival and growth of a freshwater mussel Unio crassus, from a Mediterranean stream (Sarıçay Stream) in south-west Anatolia, Turkey, which has highly variable environmental conditions and a salinity gradient. A total of 250 similarly-sized U. crassus were collected from a stream in the species’ native range and transferred in ...
متن کاملOn the reintroduction of the endangered thick-shelled river mussel Unio crassus: The importance of the river's longitudinal profile.
Freshwater mussels of the order Unionida provide important ecosystem functions and services. Unfortunately, some previously widespread species are now seriously endangered. To restore the historical range of the population of Unio crassus in the Biała River, southern Poland, the species was reintroduced into a series of 'stepping stones' joining two remnant populations. During the first phase o...
متن کاملBiological activity of pentachlorophenol on the digestive gland cells of the freshwater mussel Unio tumidus.
Many chlorinated phenols and their derivatives are used extensively as insecticides, fungicides and herbicides by industrial and agricultural users throughout the world. Among these substances, pentachlorophenol (PCP) is a broad-spectrum biocide, which is still used as a wood preservative. In this paper, the digestive gland cells were used to assess the effect of PCP in the range of concentrati...
متن کاملHost specificity and metamorphosis of the glochidium of the freshwater mussel Unio tumidiformis (Bivalvia: Unionidae).
The glochidium larvae of freshwater mussels of the family Unionidae need to find suitable hosts to attach themselves and metamorphose into free-living juveniles. The specificity of the host-parasite relationship was investigated for the Iberian Unio tumidiformis Castro, 1885 by means of experimental infections and also by analyzing naturally infected fish. The process of encapsulation of glochi...
