Fine Structure Of The Chloride Cell In The Gill Epithelium Of Brachydaniorerio(Cyprinidae, Teleostei), Sema Isisağ, Hatice Karakişi
Fine Structure Of The Chloride Cell In The Gill Epithelium Of Brachydaniorerio(Cyprinidae, Teleostei), Sema Isisağ, Hatice Karakişi
Turkish Journal of Veterinary & Animal Sciences
The main ultrastructural properties of the gill epithelium of the zebrafish, Brachydanio rerio are investigated. The pavement cells are distinguished with their microvilli, infolding protrusions and construction of an intercellular channel system, while the chloride cells sited in filamental and especially respiratory lamellar epithelia are characterized by a high number of well developed, large mitochondria and an expansive, membranous tubular system. The close relationship observed between these cell types indicates that, at least ultrastructurally, chloride cells are communicated with the external milieu via the channel system of the pavement cells.

Comparative Efficacy Of Bromadiolone, Cholecalciferol And Zinc Phosphideagainst Short -Tailed Mole Rat Nesokia Indica In Captivity, Amjad Pervez, Syed M. Ahmad, S. Waqar, A. Rizvi
Turkish Journal of Zoology
We conducted no-choice and paired choice feeding trials with individually caged Nesokia indica to evaluate the efficacy of Bromadiolone, Cholecalciferol and Zinc phosphide baits. Under no-choice test (1 day and 3 day) male rats consumed less bromadiolone bait. However, sex-wise difference was observed non-significant. Under choice feeding test, difference between bromadiolone bait intake and sex was observed non-significant. Under cholecalciferol bait, treated bait was consumed more than plain bait. Among the baits tested, cholecalciferol appeared promising for controlling short-tailed mole rat, Nesokia indica.

External, internal and karyologic characteristics of R. norvegicus were found to be consistent with previously published results. Additionally, it was determined that there are striking color variations in the dorsal and ventral fur of R. rattus and that crown morphology is not a definitive characteristic distinguishing these species because of connected lobes in old specimens. According to the karyological studies, the diploid chromosome numbers and fundamental numbers of R. norvegicus and R. rattus …
Survival And Growth Of Corophium Volutator In Organically Enrichedsediment: A Comparison Of Laboratory And Field Experiments, Levent Bat, Dave Raffaelli
Survival And Growth Of Corophium Volutator In Organically Enrichedsediment: A Comparison Of Laboratory And Field Experiments, Levent Bat, Dave Raffaelli
Turkish Journal of Zoology
In this study, the amphipod Corophium volutator (Pallas) was evaluated as test organisms for use in sediment toxicity tests by adapting standard protocols for conducting 10-day and 28-day sediment toxicity tests. Combine laboratory and field bioas-says showed that Corophium can survive in organically enriched sediment if they have no alternative, suggesting that Corophium is relatively tolerant of organically enriched sediment. Neither were there effects on emergence or reburying behaviour. Therefore this bioassay is considered inappropriate for estimating the quality of organically enricment sediment.
