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). ...

The ability of targeted and nontargeted metabolomics to discover chronic ecotoxicological effects is largely unexplored. Fenitrothion, an organophosphate pesticide, is categorized as a "red list" pollutant, being particularly hazardous to aquatic life. It acts primarily as a cholinesterase inhibitor, but evidence suggests it can also act as an androgen receptor antagonist. Whole-organism fenitr...

The theory of island biogeography predicts that the probability of a species occupying an island depends on a dynamic equilibrium between extinction and colonization. Epidermal papillomatosis is a disease manifesting as skin tumours on fish. We studied the factors affecting the occurrence of the disease in roach, Rutilus rutilus (L.), in 34 lakes. The results of discrimination analysis suggest ...

The wharf roach Ligia exotica is a small animal that lives by the sea and absorbs water from the sea through its legs by virtue of a remarkable array of small blades of micron scale. We find that the imbibition dynamics on the legs is rather complex on a microscopic scale, but on a macroscopic scale the imbibition length seems to simply scale linearly with elapsed time. This unusual dynamics of...

In the guts of more than 25 species of arthropods we observed filaments containing refractile inclusions previously discovered and named "Arthromitus" in 1849 by Joseph Leidy [Leidy, J. (1849) Proc. Acad. Nat. Sci. Philadelphia 4, 225-233]. We cultivated these microbes from boiled intestines of 10 different species of surface-cleaned soil insects and isopod crustaceans. Literature review and th...

Freshwater fish is one of the most valuable resources inland waters. Raw a perishable product, therefore, assessment product freshness important indicator its safety. In addition, in relation to freshwater fish, parasitic purity particular importance, since an intermediate host pathogens diseases transmitted humans.The studies were carried out summerautumn period.
