Ecological Succession Of Freshwater Ostracoda (Crustacea) In A Newly Developed Rheocrene Spring (Bolu, Turkey), Okan Külköylüoğlu
Turkish Journal of Zoology
Six species of ostracod (Candona neglecta, Heterocypris incongruens, Ilyocypris bradyi, Darwinula stevensoni, Pseudocandona compressa, and Psychrodromus olivaceus) were collected from a newly developed spring between October 2001 and October 2004. The first 5 species have cosmopolitan distribution in the Holarctic region. The ratio of non-cosmopolitan to cosmopolitan species (called 'pseudorichness') was 0.2, suggesting dominance of cosmopolitan species. Among the species, C. neglecta displayed the highest tolerance to 6 different environmental variables, although its estimated optimum values varied. Except foor redox potential and salinity, optimum values for H. incongruens were the highest. High tolerance and optimum values seemed to provide more …

Effects Of Carbaryl And Γ-Bhc On The Histology Of Midgut And Digestive Enzyme Profiles In The Third Instar Larvae Of Fruit-Sucking Moth, Othreis Materna (Linn.) (Lepidoptera: Noctuidae), Chitralekha Deshmukh, Aneel Mohite, Jagdish Shinde
Turkish Journal of Zoology
The effects of LC50 dose of carbaryl and gamma benzene hexachloride (γ-BHC) on midgut histopathology and midgut enzyme activities in the third instar larvae of fruit-sucking moth, Othreis materna (L.) were studied. The sub-lethal doses of carbaryl and \gamma-BHC caused initially hypersecretory activity in the midgut epithelial cells leading to deposition of numerous secretory vesicles in the extraperitrophic space, clumping of chromatin matter, and regression and vacuolization of the columnar cells, but later on they were recovered within 24 h. Activities of the midgut digestive enzymes (amylase, invertase, lipase, and protease) were significantly affected. Carbaryl enhanced (P < 0.05) the amylase, invertase, lipase, and protease activities initially up to 4 h and 6 h of treatment, but after 24 h of treatment, amylase and invertase activities resumed while an inhibitory effect was observed on lipase and protease activities. \gamma-BHC did not affect the amylase and protease activities up to 4 h but later on it significantly (P < 0.05) enhanced their activities up to 6 h and 12 h, respectively. Thereafter it fell without showing any sign of recovery. \gamma-BHC enhanced (P < 0.05) invertase and lipase activities but they fell after 4 h treatment.
