Context. Invasive species are a growing global problem. Biological invasions can result in numerous harmful impacts on local ecologies, and non-native herpetofauna are frequently ignored. Nile monitor lizards (Varanus niloticus) and Burmese pythons (Pythonmolurus bivittatus, recently reassessed asPython bivittatus bivittatus), have become established in(More)
Tissues of coyotes and magpies administered known dosages of 1080 were analyzed for residues by an analytical method specifying gas chromatography and electron capture detection. The repeatability of the method was determined for the replicate analyses of coyote muscle tissue samples aged under different storage conditions. The average coefficient of(More)
There exists a structure-toxicity relationship between the length of the alkyl chain of p-aminopropiophenone homologues and their oral LD50's in albino mice and rats. The acute oral toxicity decreased in both species with the removal of one carbon atom from the alkyl group, increased with the addition of one and two carbon atoms, and decreased again with(More)
A wide variety of chemicals including dyes, stains, inks, drugs, fluorescent and non-fluorescent particles, and radioisotopes have been used as markers to identify free-ranging mammals and birds. Markers are useful for studying: (1) home ranges, migration patterns, and population dynamics; (2) bait acceptance, palatability, and exposure of target animals(More)
To evaluate the potential of using nesting material as a medium for avicide delivery, five organophosphates (Dasanit*, Volaton®, fenthion, parathion, and Cyanophos*) were tested on small groups of paired malefemale quelea (n = 4 to 9). Toxicants were presented to each pair of birds on five 13-cm strands of cotton string after a preliminary screening for(More)
Tartrazine was examined as a possible replacement marker for rhodamine B in the Livestock Protection Collar. Test solutions were formulated in six combinations; tartrazine at 0.5% and 1.07. concentrations, with and without compound 1080, and with and without nigrosin black. Each solution was examined for persistence of color in the laboratory and when(More)
