A review of research published in a 2015 issue of "Journal of Applied Ecology" is presented which found cane toad tadpoles suppressed the growth of tadpoles and reduced the embryo survival to under five percent when separated from them with a mesh partition but kept in the same container and ...
For example, a toxic toad in its native range is likely to be confronted with predators that either are unaffected by its toxic arsenal (small genetic changes to predator physiology confer many thousandfold resistance20) or have evolved to exclude large toads from the diet21,22. Thus, increased...
Spores were only detected in frogs collected post-1966, supporting the ‘cane toad introduction theory’. However, further examination suggested that Hawaiian cane toads (the source population of Australian cane toads) were Myxidium-free, and that the parasites of Brazilian cane toads are genetically...
Blood parasites were completely lost, possibly due to their absence from the small founder population, or a lack of vectors in the introduced range (Delvinquier and Freeland, 1988b). Table 1. Species of native-range protozoan parasites retained by the Australian cane toad in Queensland. ...
Here we demonstrate that, contrary to our expectations, spondylosis cannot be predicted by invasion history or leg length in toad populations across the Australian landscape but rather, the size of an individual and the lati- tude of occurrence of the population are the most important predictors ...
After the Genesis Flood, there was little resistance to animal invasion all around the world, with successive population waves of animals being able to readily occupy “empty” ecological niches in all directions.3 References Killing off the cane toad, The University of Queensland—Institute for ...
Pathological effects of infection on the cane toad host appeared relatively minor. Histopathological differences in lung tissue were detected between treatment groups, but the cellular changes were subtle. Similarly mild pathological consequences of infection were recorded in a South American population of ...
The country’s cane toad population now numbers in the millions and covers most of northeastern Australia. The toads are advancing westward by 40–60 km (25–40 miles) per year. In response, the Australian government is taking active measures to humanely reduce their numbers. Other regions ...
