Physiological And Toxicological Effects Of Pb Plus Cd Mixtures On Rainbow Trout (Oncorhynchus Mykiss) In Soft Acidic Water, Yvonne Kara

Theses and Dissertations (Comprehensive)

The ability of a metal to cause toxicity in aquatic environments is highly dependant upon the water chemistry, which can influence metal bioavailability. Metal bioavailability is affected by the concentration of the metal, complexation of the metal by organic and inorganic ligands, and by the speciation of the metal. Predictive models of metal toxicity, such as the biotic ligand model (BLM) have mainly focused upon predicting the toxicity of individual metals rather than the toxicity of metals in mixtures, which are more commonly found in contaminated waters. Two metals that are commonly found together are Pb and Cd which can …

Lobster Attack Induces Sensitization In The Sea Hare, Aplysia Californica, Amanda J. Watkins, Daniel A. Goldstein, Lucy C. Lee, Christina J. Pepino, Scott L. Tillett, Francis E. Ross, Elizabeth M. Wilder, Virginia A. Zachary, William G. Wright

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Studies of the neural mechanisms of learning, especially of sensitization, have benefitted from extensive research on the model species, Aplysia californica (hereafter Aplysia). Considering this volume of literature on mechanisms, it is surprising that our understanding of the ecological context of sensitization in Aplysia is completely lacking. Indeed, the widespread use of strong electric shock to induce sensitization (an enhancement of withdrawal reflexes following noxious stimulation) is completely unnatural and leaves unanswered the question of whether this simple form of learning has any ecological relevance. We hypothesized that sublethal attack by a co-occurring predator, the spiny lobster, Panulirus interruptus, might …

All-Trans Retinoic Acid Regulates Intracellular Redox Status In Marc-145 Cells Infected With Porcine Reproductive And Respiratory Syndrome Virus, Yan Lin, De Wu

Turkish Journal of Veterinary & Animal Sciences

A relationship between oxidative stress, and apoptosis and/or death has been suggested for many years. The objective of this study was to determine the influence of all-trans retinoic acid (ATRA) on the cell survival rate and the antioxidant defense system. MARC-145 cells were treated with ATRA after infection with porcine reproductive and respiratory syndrome virus (PRRSV).

Impairments In Haematological Parameters Of Saprolegnia Spp. Infected Tench,Tinca Tinca, Syed Lal Shah

Turkish Journal of Veterinary & Animal Sciences

Haematological parameters of tench (Tinca tinca) infected by Saprolegnia spp. were studied. All parameters, except mean corpuscular volume (MCV), decreased in response to infection. A significant (P < 0.05) decrease was observed in haemoglobin (Hb) (-26.85%), red blood cell count (RBCc) (-20.94%), leucocrit (Lct) (-24.14%), and mean corpuscular haemoglobin concentration (MCHC) (-9.06%). Haematocrit (Hct), white blood cell count (WBCc), and mean corpuscular haemoglobin (MCH) also decreased (-7.66%, -12.44%, and -6.19%, respectively); however, differences between the infected and control groups were not significant. Among the parameters, only MCV had a non-significant increase (+7.84%) in the infected fish. The study results show that saprolegniasis caused anaemia and immunosuppression, followed by mortality in tench. Mortality was attributed to haemodilution caused by haemorrhaging and the breakdown of osmotic balance due to tissue (skin and muscular layer) destruction via the penetration of the hyphae; however, lethargy was another mortality promoting factor. Mortality among the Saprolegnia-infected fish also depended upon the initial site of infection, type of tissue destroyed, growth rate of the fungus, and ability of individual fish to withstand the stress. The present study was conducted to investigate physiological impairment in Saprolegnia-infected Tinca tinca under laboratory conditions; however, further studies at the population level in natural habitats and under similar stress conditions are needed.

An Effective Chemical Deterrent For Invasive Cuban Treefrogs, Steve A. Johnson, Monica E. Mcgarrity, Christina L. Staudhammer

Human–Wildlife Interactions

Introduced vertebrates have a variety of impacts on ecosystems and economies, and many cause problems for humans. One such problem is the loss of electrical power when invasive animals cause short circuits in power-transmission equipment. Cuban treefrogs (Osteopilus septentrionalis) are known to cause power outages and are a nuisance to humans when they invade homes and defecate on doors and windows. These large, slightly toxic treefrogs were introduced into Florida from the Caribbean. They now occur throughout the peninsula of Florida and are spreading to other states in the Southeast. We used refuge choice experiments to test the …
