A Model Host-pathogen System for Studying Infectious Disease Dynamics in Amphibians: Tiger Salamanders (ambystoma Tigrinum) and Ambystoma Tigrinum Virus
Pathogens are among the suspected causes of declining amphibian populations, but studying infectious diseases in small, threatened populations is ethically and experimentally questionable. Progress on understanding amphibian diseases requires model host-pathogen systems with populations large enough for robust experimental designs that do not threaten the amphibian host with extinction. We repo...
متن کاملLoading mechanics of the femur in tiger salamanders (Ambystoma tigrinum) during terrestrial locomotion.
Salamanders are often used as representatives of the basal tetrapod body plan in functional studies, but little is known about the loads experienced by their limb bones during locomotion. Although salamanders' slow walking speeds might lead to low locomotor forces and limb bone stresses similar to those of non-avian reptiles, their highly sprawled posture combined with relatively small limb bon...
متن کاملOntogenic delays in effects of nitrite exposure on tiger salamanders (Ambystoma tigrinum tigrinum) and wood frogs (Rana sylvatica).
Under certain conditions, nitrite can be present in freshwater systems in quantities that are toxic to the fauna. I exposed wood frog (Rana sylvatica) and eastern tiger salamander (Ambystoma tigrinum tigrinum) embryos and young tadpoles and larvae to elevated concentrations of nitrite in chronic toxicity tests: 0, 0.3, 0.6, 1.2, 2.1, 4.6, and 6.1 mg/L NO2-N, exposing individuals as both embryos...
متن کاملPhenotypically Plastic Responses of Larval Tiger Salamanders, Ambystoma tigrinum, to Different Predators
—Studies of prey responses to different predators are needed to investigate costs and benefits of particular antipredator responses and to unravel community-level effects on phenotypic plasticity. We reared laboratory-bred larvae of Arizona Tiger Salamanders, Ambystoma tigrinum nebulosum with either of two common predators, diving beetle larvae (Dytiscus sp.) or dragonfly naiads (Anax junius). ...
متن کاملAtrazine increases ranavirus susceptibility in the tiger salamander, Ambystoma tigrinum.
Pathogenic diseases and environmental contaminants are two of the leading hypotheses for global amphibian declines, yet few studies have examined the influence of contaminants on disease susceptibility. In this study, we examined effects of ecologically relevant doses of atrazine (0, 1.6, 16, and 160 microg/L), sodium nitrate (0, 6.8, 68 mg/L), and their interactions on susceptibility of four l...
