... was significantly outside the range exhibited by the other two treatments in terms of tadpole growth and there was no clear evidence of any indirect chemically-based interactions between tadpoles of the two species. As this study has provided no indication that there may be inter-specific interactions between...

.... That advantage has outweighed occasional cases where a snake is fatally poisoned by consuming a toad. Thus, the overall impact of Cane Toads on Carpet Pythons (and likely, other predator species) is a balance between direct costs and indirect benefits. Negative impacts on individuals may not necessarily...

... to the absence of the top-down control of dingo predation. This hypothesis has since been widely supported in empirical studies (Caughley et al. 1980; Pople et al. 2000; Letnic and Koch 2010). More recently, research has focussed on the indirect effects that removal of dingoes has on ecosystems (Letnic et al...

(3) Fire history (e.g. the number of past fires and the time since the previous fire). And, (4) Interactions between fire and other ecosystem drivers such as logging. We...

... out from the harbour foreshore by the direct effects of the plague and the indirect effects arising from rat persecution to prevent plague, making the arrival of bubonic plague in the 1900s a disaster for Sydney's foreshore wildlife. If this hypothesis is correct, then future attempts to restore Bush...

... of biodiversity surveys and environmental impact assessments across Australia and wherever detailed knowledge of population demography is required. The data quality derived from live-trapping is typically superior to other indirect means of mammal sampling, such as hair traps, tracking stations or sand traps...

... ability to survive the presence of toads postmetamorphosis. Predicting the ecological impacts of an invasive species on native taxa with biphasic life histories (such as most anurans) thus requires information on interactions in both aquatic and terrestrial environments. The expression of phenotypic...

Declines in shellfish reefs are due to both direct and indirect effects of coastal development...

..., individual effects of climate- change factors such as changes to habitat, temperature and pH, but also to their indirect, interactive effects with other factors that are likely to become more important, especially beach nourishment and hard engineering.

... of the base of Split Rock suggesting that they frequent this locality. Since no direct observations of rock- wallabies were made, and no indirect evidence of their presence found, it was decided that no further investigation would be carried out at this area. 2.

...; and the potential for interaction between hunting dogs and wild dogs in remote areas, particularly during the wet season. These observations can be used to inform disease spread models and identify strategies to mitigate the risks of disease transmission. However, the collection and incorporation of data...

... with a partly masticated toad in its oesophagus. This, and other indirect evidence, indicates that Cane Toads are being taken by Ghost Bats on an occasional basis and that these episodic predation events may be a significant factor in the observed decline in Ghost Bats populations in areas where Cane Toads...
