Myxobolus gayerae sp. n. and M. leuciscini González-Lanza & Alvarez-Pellitero, 1985 (Myxozoa: Myxobolidae) have been described and re-described from European chub Leuciscus cephalus L. from the Hungarian stretch of the river Danube. The ellipsoidal plasmodia of M. gayerae sp. n. were found in the mucosa of the intestinal wall, whereas the large, elongated plasmodia of M. leuciscini infected the...

Airborne LiDAR Bathymetry (ALB) has been rapidly evolving in recent years and now allows fluvial topography to be mapped in high resolution (>20 points/m) and height accuracy (<10 cm) for both the aquatic and the riparian area. This article presents methods for enhanced modeling and monitoring of instream mesoand microhabitats based on multitemporal data acquisition. This is demonstrated for a ...

Rapid water level decreases due to hydropeaking are known negatively affect riverine biota, mainly the stranding of organisms in river bank area that becomes regularly dewatered. Even though studies last decades have focused on salmonid fish, also cyprinids may be affected. However, limited knowledge is available this fish family. Therefore, we conducted mesocosm experiments under semi-natural ...
