The effect of rapeseed oil methyl ether (RME) on cladocerans (water flea Daphnia magna Straus) and fish embryos prolarvae (round goby Neogobius melanostomus (Pallas)) is investigated. It has been determined that, with the increase RME content in water, decrease survival rate, fecundity, abundance, biomass population observed, as well rate round fry linear weight growth fry. did not produce any ...

Late Pleistocene remains of Microtus oeconomus (PALLAS, 1776), a species that is not any more a member of the extant fauna of Croatia, have been recently found in Vindija Cave sediments. The sample of 21 teeth shows a slight increase of M1 length and decrease of A/L ratio within the cave sequence from older (G complex; 32 to 42 ka) towards younger strata (E+F complex; layer E is dated at ca. 18...

We report on the crystallization of laser cooled Mg+ ion beams circulating in the table-top rf quadrupole storage ring PALLAS at a velocity of 2800 m/s (beam energy 1 eV). A sudden collapse of the transverse beam size and the low velocity spread clearly indicate the phase transition to a onedimensional linear string of ions. This crystalline beam shows exceptional stability, surviving for more ...

In order to study the culicine mosquito fauna (Diptera: Culicidae: Culicinae) of the Shadegan wetland in southern Khouzestan Province of Iran, sampling was carried out using hand catch, total catch, and New Jersy light traps, from October 2008 to March 2009. A total of 2664 culicine mosquitoes were captured. Three genera and five species were identified, including Culex pipiens L., Cx. tritaeni...

Two cestode species, Fimbriaria fasciolaris (Pallas, 1781) Frölich, 1802 Cloacotaenia megalops (Nitzsch in Creplin, 1829) Wolffhügel, 1938 collected from Anas bahamensis Linné, 1758 and Amazonetta brasiliensis (Gmelin, 1758) in lagoons of the Maricá District, State of Rio de Janeiro, Brazil, are described. This is the first record of F. fasciolaris parasitizing A. bahamensis. The prevalence, in...
