In June 2011, 34 specimens of round goby (Neogobius melanostomus) were caught at three different locations in the Sava River in Croatia, which is a first record of this invasive species in Danube tributaries in Croatia. Size, structure and condition of populations indicate that the species is well adjusted to its new habitat and that further range expansions are highly likely.

Large boreal rivers in Sweden are generally impounded by hydropower dams and a large proportion of main stem shallow flowing habitats have been lost. Tributaries often contain the last undisturbed could be important for conservation species diversity. In particular, tributary mouth areas biodiversity hot-spots, due to their vicinity favorable environmental conditions. this study, we investigate...

The veins of the azygos system vary greatly in mode of origin, course, numbers of tributaries and anastomoses, and nature of termination. The azygos vein system can take different courses. Such variation is important in mediastinal surgery, and knowledge of congenital variations can be of clinical importance. It is imperative for reporting radiologists to identify such anomalies.

Gyrodactylus latus Bychowsky, 1933 (Monogenea, Gyrodactylidae) was found on fins of Cobitis elongatoides Bacescu et Maier, 1969 (Teleostei, Cobitidae) from tributaries of the Stobrawa River (Odra Basin, Silesia, Poland). It is new to the Polish parasite fauna; its description, measurements, and figures are presented.

Some ecological restoration projects include elements of trial and error where new measures are repeatedly tried, evaluated, and modified until satisfactory results are achieved. Thereafter, the resulting methods may be applied on larger scales. A difficult step is judging whether developed “best-practice” methods have become reasonably ecologically functional or whether further experimentation...

Background: Percutaneous nephrostolithotomy is an important approach for removing kidney stones. Puncturing and dilatation are two mandatory steps in percutaneous nephrolithotomy (PCNL). Uncommonly, during dilatation, the dilators can cause direct injury to the main renal vein or to their tributaries. Case Presentation: A 75-year-old female underwent PCNL for partial staghorn stone in the left ...

OBJECTIVE To assess the clinical and duplex ultrasound scan findings in the groin and thigh 2 years after great saphenous vein (GSV) radiofrequency endovenous obliteration (RFO). METHODS Sixty-three limbs in 56 patients with symptomatic varicose veins and GSV incompetence were treated with RFO, usually with adjunctive stab-avulsion phlebectomies, and examined at a median follow-up of 25 month...
