Lay summaries: Since little is known about invertebrate steroid hormones, we established a cortisol extraction and quantification protocol via ELISA in mussels, in the model organism Anodonta anatina. Additionally, we quantified cortisol biodistribution and redistribution in five different tissues after treatment with either copper (II) chloride, sodium chloride or algae feed.

This study is devoted mainly to the distribution and its changes, inhabited and preferable habitats of bivalves from family Unionidae in the territory of the Czech Republic and the discussion of major threats and conservation measures. Altogether 6 autochthonous (Unio crassus, Unio pictorum, Unio tumidus, Anodonta anatina, Anodonta cygnea, Pseudanodonta complanata) and 1 allochthonous species (Sinanodonta woodiana) has been known in the Czech Republic. All these species occurred in all three river basins (Labe, Odra, Danube) and watersheds (North, Baltic and Black seas). A. anatina is the most widespread and common unionid while P. complanata is an autochthonous bivalve with the most restricted area of distribution. U. crassus has been a significantly disappearing species. As in most European countries, pollution and habitat loss including fragmentation and degradation, together with other factors such as water abstraction, invasive species and loss of fish hosts are the main threats affecting their populations.

AbstractA comparative study has been made of the haptoral morphology of four species of diplozoon (Monogenea: Diplozoidae) from the gills of fish exposed to different levels of water pollution in two river systems in eastern Europe. An examination of the haptors of Paradiplozoon homoion (Bychowsky & Nagibina 1959), Paradiplozoon ergensi (Pejčoch 1968) and Paradiplozoon megan (Bychowsky & Nagibina 1959) from chub caught in the River Morava, Czech Republic and of Diplozoon paradoxum (Nordmann 1832) from bream recovered from the River Volga, Russia has revealed abnormalities to the attachment clamps. Two abnormal conditions were found: structural alterations to the attachment clamps and changes in the number of attachment clamps; these occurred both singly and in combination. A higher frequency of abnormal attachment clamps was found in diplozoons from fish caught in the more polluted localities of both rivers. The abnormalities have been recorded and their morphology compared in the light of conditions of environmental stress.
