Acute Toxicity Of Carbaryl, Methiocarb, And Carbosulfan To The Rainbow Trout (Oncorhynchus Mykiss) And Guppy (Poecilia Reticulata), Muhammet Boran, İlhan Altinok, Erol Çapkin, Hi̇kmet Karaçam, Veysel Bi̇çer

Turkish Journal of Veterinary & Animal Sciences

The acute toxicity of carbaryl, methiocarb and carbosulfan to juvenile rainbow trout (Oncorhynchus mykiss; 1.92 ± 0.5 g) and guppies (Poecilia reticulata; 0.45 ± 0.04 g) was evaluated in 96-h toxicity tests under static conditions. Concentrations in the toxicity test ranged from 0.85 to 8.5 mg/l for carbaryl, from 0.7 to 28.0 mg/l for methiocarb, and from 0.031 to 12.5 mg/l for carbosulfan. Carbaryl and methiocarb were more toxic to rainbow trout than to guppies. However, compared with rainbow trout, guppies were more sensitive to carbosulfan. The incidence of mortality in fish increased significantly (P < 0.05) with increasing pesticide concentrations. The time required to kill 50% (LT_{50}) of the rainbow trout at the lowest concentrations of carbaryl, methiocarb, and carbosulfan was 51 h 12 min, 74 h 35 min, and 107 h 57 min, respectively. As insecticide concentrations were increased, LT_{50} values decreased (P < 0.05).

Investigation Of Some Biochemical Parameters And The Antioxidant System In Calves With Dermatophytosis, Mahmut Karapehli̇van, Erdoğan Uzlu, Necati̇ Kaya, Orhan Kankavi̇, Kerem Ural, Mehmet Çi̇ti̇l

Turkish Journal of Veterinary & Animal Sciences

The study included 10 clinically healthy calves (group 1) and 10 clinical cases of dermatophytosis (group 2). The influence of dermatophytosis on some serum biochemical profiles and the antioxidant system was investigated. Serum malondialdehyde (MDA), reduced glutathione (GSH), uric acid, nitric oxide (NO), total sialic acid (TSA), lipid-bound sialic acid (LBSA), total protein (TP), and albumin levels were measured in groups 1 and 2. Calves in group 2 had significantly higher (P < 0.001) MDA, NO, TSA, and LBSA levels, and a higher P < 0.01 TSA:TP ratio; however, GSH and uric acid levels were significantly lower (P < 0.001). There was no significant difference between the groups in total protein and albumin. These findings suggest a relationship between dermatophytosis, the antioxidant system, and lipid oxidation.

Modelling The Protein And Amino Acid Requirements Of The Greater Rhea (Rhea Americana), James Sales Jan 2007

Modelling The Protein And Amino Acid Requirements Of The Greater Rhea (Rhea Americana), James Sales

Turkish Journal of Veterinary & Animal Sciences

Protein and amino acid requirements of the Greater rhea (Rhea americana) have been estimated from growth data available for this species, and assumptions derived with other closely related species. Differences in body weight and growth pattern caused considerable higher protein and amino acid requirements for males compared to females after 3 months of age. Whereas the absolute protein requirement is comparable between males (148 g/day) and females (144.5 g/day) at 50 days of age, 21.8 g/day protein is needed by males at 500 days of age compared to 12.2 g/day for females. Limitations include the lack of knowledge on feed …

Genetic Diversity And Low Reproductive Success In Isolated Populations Of Utah Juniper (Juniperus Osteosperma, Cupressaceae), Loreen Allphin, Val J. Anderson, Amy F. Hunt

Faculty Publications

Utah juniper (Juniperus osteosperma) has greatly expanded its historical range in the western United States. Management plans for the species have focused on curtailing its encroachment into sagebrush and grassland communities. These plans often include burning or other methods of elimination. These methods may result in subdivision or fragmentation of existing juniper stands. We initiated a study at Dugway Proving Ground, a U.S. Army facility, to examine the effects of fragmentation on the reproductive success of Utah juniper in isolated populations. We used enzyme electrophoresis to quantify genetic variability in isolated populations. We also determined population reproductive success by examining …

Differential Classical Conditioning Of The Gill-Withdrawal Reflex In Aplysia Recruits Both Nmda Receptor-Dependent Enhancement And Nmda Receptor-Dependent Depression Of The Reflex, Shekib A. Jami, William G. Wright, David L. Glanzman

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Differential classical conditioning of the gill-withdrawal response (GWR) in Aplysia can be elicited by training in which a conditioned stimulus (CS) delivered to one side of the siphon (the CS+) is paired with a noxious unconditioned stimulus (US; tail shock), while a second conditioned stimulus (the CS-), delivered to a different siphon site, is unpaired with the US. NMDA receptor(NMDAR) activation has been shown previously to be critical for nondifferential classical conditioning in Aplysia. Here, we used a semi-intact preparation to test whether differential classical conditioning of the GWR also depends on activation of NMDARs. Differential training produced conditioned enhancement …
