Description:
Bacciger israelensis Fischthal, 1980 (Trematoda: Fellodistomidae) was recorded from Boops boops (Perciformes: Sparidae) in Bulgarian Black Sea coastal waters for the first time. Re-examination of the morphology of B. israelensis showed some new details: Laurer’s canal opens dorsally a short distance anterior to the excretory pore; seminal receptacle situated posterior to ventral sucker and ventral to ovary; ovary composed of three nearly spherical but not separated lobes forming apexes of isosceles triangle; tegumental spines covering body including entire surface of ventral sucker and distal half of upper part of oral sucker.

Description:
Brachylecithum microtesticulatum Timon-David, 1955 (Digenea: Dicrocoeliidae) is recorded for the first time in the Black Sea region. The morphology and variability of the digeneans recovered from Larus argentatus in Bulgaria and the Ukraine are described and compared with the redescription of the species (Bartoli and Mas-Coma 1989). Lyperosomum lari Travassos, 1917 of Smogorzhevskaya (1976) is considered a synonym of B. microtesticulatum.

Description:
In the Southeastern Black Sea Region, rivers are dammed for hydroelectric power and irrigation. The natural course of fluvial alluvium transport is almost completely altered because of planned and constructed dams and coastal protection measures. Decreasing volume of sediment carried to the sea cause intensification of the shore erosion. The Black Sea Rivers and coastal areas of Turkey and Georgia are under heavy anthropogenic pressure because of the bed material extraction and coastal erosion rate. In this study, environmental effects of dams and related effects of sediment transport on coastal erosion in the Eastern Black Sea region are discussed. and Rieky v juhovýchodnej časti regiónu Čierneho mora sú prehradené priehradami, ktoré slúžia na výrobu elektrickej energie a na závlahy. Prirodzený transport plavenín a splavenín sa v dôsledku výstavby plánovaných a realizovaných priehrad takmer úplne zmenil. Znížený objem sedimentov dopravovaných do mora spôsobuje intenzifikáciu erózie brehov riek. Rieky ústiace do Čierneho mora v oblasti pobrežia Turecka a Gruzínska sú výrazne ovplyvnené ľudskou činnosťou, ako je ťažba materiálu z riek a eróziou brehov. V tejto práci sa analyzuje vplyv priehrad na životné prostredie krajiny vo východnej časti Čierneho mora.
