Specialists studying the genus Viola have consistently allied the Hawaiian violets comprising section Nosphinium--most of which are subshrubs or treelets--with putatively primitive subshrubs in certain South American violet groups. Hawaiian violets also possess inflorescences, a floral disposition otherwise found only in other genera of the Violaceae, thus strengthening the hypothesis of a very...

Seasonal occurrence of metazoan ectoparasites is described for the first time in marine European flounder, Platichthys flesus (L.). The parasitofauna, in this study monitored during 1 year, was found to be similar to that previously recorded for flounder. Moreover, specimens of Caligus sp. Müller, 1785 and Lepeophtheirus pectoralis (Copepoda: Caligidae), Acanthochondria cornuta (Copepoda: Chond...

A study was carried out in restored South West Lake and non-restored East Lake, of Beira lake with the objective of determining the species composition, density and distribution of zooplankton. Water was sampled from the surface and at a depth of 1 m, from February to March, 2005 between 0900-1130 h. Three rotifers species; Brachinonus calyciflorus, Keratella tropica, Filinia sp., three cladoce...

The species composition and abundance of the zooplankton community of seven reservoirs of the Paranapanema River, located between 22 degrees 37'-23 degrees 11'S and 48 degrees 55'-50 degrees 32'W, were analysed over four periods, in the year of 1979. The zooplankton community was composed of 76 species of Rotifera, 26 species of Cladocera and 7 species of Copepoda. For a large part of the perio...

Objective: Viola odorata has been used since ancient times. According to Traditional Iranian Medicine (TIM) sources, it a cool and moist temperament is for treatment of different diseases. Due the low side effects numerous beneficial this plant, study aims review its therapeutic from perspective TIM modern medicine. Methods: In study, search was conducted materials in many books such as Canon M...

In this thesis the chemical composition of heartsease (Viola tricolor L.) was studied to support the evidence-based determination of its biological activities. Henceforth, a proper sample preparationmethodwas developed, yielding a fraction rich on polar constituents (characteristic of the traditionally applied aqueous extract), which was further separated by conventional Sephadex LH-20 column c...

The meadow violet ( Viola pumila Chaix) is an endangered species which regionally extinct in many European countries. This a stenobiontic with very limited distribution Bulgaria. Only few populations have been detected, and they consist of several tens to hundreds specimens. has reproductive abilities weak competitiveness. exposed various anthropogenic threats, as the most significant them are ...
