Sexual ornamentation, androgens and papillomatosis in male roach (Rutilus rutilus)
According to the immunocompetence handicap hypothesis, males with attractive sexual ornamentation are more handicapped than their less ornamented rivals because of the immunosuppressive androgens required for the production of secondary sexual characters. Here we studied the predictions of the hypothesis in a wild cyprinid fish, the roach (Rutilus rutilus). We assayed (1) sexual ornamentation (...
متن کاملLaboratory and field studies with 32P labeled Toxorhynchites rutilus rutilus.
Females and eggs of Toxorhynchites r. rutilus were labeled with 32P by feeding fourth-stage larvae 32P labeled Aedes aegypti larvae. Eggs from females up to 3 weeks in age had detectable levels of radioactivity and individual eggs contained ca. 0.3% of the mother's total radioactivity. Comparisons of labeled and unlabeled females in indoor and outdoor cage tests indicated that survival and fecu...
متن کاملThe destructive effects of Diazinon on gill tissue of Caspian roach fingerling (Rutilus caspicus)
One hundred and five fish with an average weight of 2.5 g from the aquaculture center in the port of Turkmen, Golestan province, were cached, sub-lethal test was for 1 week with 5 treated of diazinon as 0, 25, 50, 75 and 90% of LC50 (0, 0.42, 0.85, 1.28 and 1.17 ppm, respectively). The results showed that with progress of poison, gill tissue lesions will be increased such as hyperemia and hemor...
متن کاملstudy of hg effects on liver tissue in rutilus rutilus of caspian sea in vitro
a series of specific toxicological effects including bioaccumulation of the pollutant, histological changes and influences on liver tissue were examined in the roach fish (rutilus rutilus) after the exposure to graded sublethal concentrations (10 , 30 , 50 μg hg/l) of mercury chloride (mc). histopathological changes, such as oedema, vacuolization, pyknotic nucleus, telangiectasis, and degenerat...
متن کاملFactors affecting between-lake variation in the occurrence of epidermal papillomatosis in roach, Rutilus rutilus (L.).
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 ...
