the research was accomplished in order to study behavioral and histopathological effects of copper on rutilus rutilus caspicus under experimental condition. the study was performed using water static method during 96 hours. 15 fish with averaged weight 2?0.5 g in weight were encountered to different concentrations (0, 0.1, 0.2, 0.3, 0.4 mg/l) of copper. a group of fish was considered as control...

The coexistence of competing species relies on niche partitioning. Competitive exclusion is likely inevitable at high niche overlap, but such divide between competitors may be bridged if environmental circumstances displace competitor niches to enhance partitioning. Foraging-niche dimension can be influenced by environmental characteristics, and if competitors react differently to such conditio...

Protein synthesis by a rabbit reticulocyte lysate is inhibited by the haemagglutinating lectins from Momordica charantia and Crotalaria juncea seeds and from the roe of Rutilus rutilus, and by a commercial preparation of the mitogenic lectin from Phytolacca americana. The haemagglutinins from the seeds of Ricinus communis and of Vicia cracca acquired inhibitory activity after their reduction wi...

An environment intensively studied from many perspectives, through the efforts of an interdisciplinary team of biologists, ecologists, geneticists, chemists, pedologists, etc. is Moara Domnească agroecosystem. Located in the North-East of Bucharest, the Moara Domnească Lake is used for irrigation of the neighbouring agricultural areas and also for pisciculture (Stavrescu-Bedivan et al., 2011). ...

Larvae of the mosquito Toxorhynchites rutilus (Coquillett) prey upon other container-dwelling insects, including larvae of Aedes albopictus (Skuse), which is native to Asia but was introduced into the United States, and on the native tree hole mosquito Ochlerotatus triseriatus (Say). Previous work has established that O. triseriatus adopts low-risk behaviors in the presence of predation risk fr...
