Molecular detection and genome analysis of circoviruses of European eel (Anguilla anguilla) and sichel (Pelecus cultratus).
The prevalence and distribution of piscine circoviruses (CVs) were tested in a routine virus monitoring programme in Lake Balaton, Hungary. A high prevalence of European eel CV (EeCV) was found in the apparently healthy eel population (35.5%). The copy number of the viral DNA in different organs was determined by quantitative real-time PCR. The results suggested that some eel specimens were in ...
متن کاملN ov 1 99 2 Multiple W L Production From Inelastic W L W L Scattering At √ ŝ ≫
We explore the inelastic production of multiple longitudinal weak bosons as a manifestation of a strongly interacting symmetry breaking sector. By analogy with QCD, final states with large multiplicities are expected to occur not far above the energy scale of the lowest resonances of the underlying strong theory. We consider the feasibility of observing such phenomena in the environment of a ve...

متن کاملTime-place learning in golden shiners (Pisces: Cyprinidae).
The goal of this study was to determine whether fish can learn to forage in different places at different times of the day, each place being associated with a specific time. Groups of eight golden shiners (Notemigonus crysoleucas) were kept in aquaria equipped with automatic feeders that dropped food on one side in the morning and on the other side in the afternoon, or on one side in the mornin...
متن کاملPebble nest microhabitats of Semotilus species (Pisces: Cyprinidae)
The pebble nest microhabitats of four species of Semotilus were compared. Pit/mound nests of Semotilus corporalis were significantly larger than the pit/ridge nests of Semotilus atromaculatus, Semotilus lumbee, and Semotilus thoreauianus. Nests of S. corporalis were in wider and deeper streams. Pits of S. lumbee nests were longest of the four species; those of S. corporalis were widest and deep...
