Preliminary field assessment of a cabergoline baiting campaign for reproductive control of red fox (Vulpes vulpes).

The use of poison baiting to control foxes is impractical in urban areas and some wildlife reserves because of hazards to non-target animals. More acceptable methods of fox control in such environments are needed. Cabergoline is a dopamine agonist that has previously been demonstrated to have an abortifacient effect in cats (Felis catus) and dogs [...]

Techniques for using Rhodamine B as systemic biomarker for the assessment of non-target risk

The dye Rhodamine B (RB) has been found to act as a persistent systemic biomarker in laboratory trials with rabbits and rats. Rhodamine B is incorporated post-ingestion into actively growing hair and claws to produce a band which appears fluorescent under ultraviolet illumination. A possible mechanism for the production of these bands is described. Characteristics [...]

Evaluation of iophenoxic acid as a biomarker for swamp wallabies (Wallabia bicolor).

The potential of iophenoxic acid (IPA) as a systemic biomarker for use in feeding and diet studies of swamp wallabies (Wallabia bicolor) was investigated. Groups of captive wallabies were administered IPA doses of 0, 15 and 30 mg kg-l. Baseline concentrations of plasma iodine were compared with samples taken at 24 h, 48 h, 4 [...]

The uptake of dried meat baits by foxes and investigations of baiting rates in Western Australia

The uptake of dried meat baits by foxes (Vulpes vulpes) was measured in large-scale field trials using non-toxic baits containing the biomarker tetracycline. Baits were aerially delivered at nominal baiting rates of 5 baits km–2 (4 sites) and 10 baits km–2 (3 sites). The proportion of sampled adult foxes that had consumed the bio-marked baits [...]

Iophenoxic acid as a biomarker for rabbits (Oryctolagus cuniculus)

In recent years, research has shown that iophenoxic acid is useful as a biomarker in mammals. Its potential was initially demonstrated in several species of carnivores but it has since been found to be suitable for use in two species of herbivore, goats (Capra hircus) and deer (Odocoileus virginianus). We investigated its suitability for use [...]

IOPHENOXIC AND IOPANOIC ACID AS BAIT MARKERS FOR FERAL GOATS.

As part of assessments of the palatability of different formulations for baits to be used for the control of feral goats, iopanoic acid and iophenoxic acid were compared as bait markers. After goats ingested iopanoic acid (25, 50 and 100 mg/kg), peak plasma iodine concentrations (4.86, 17.25 and 19.11 micro g/ml respectively) were reached after [...]
