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.

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.
