Is the behavioural divergence between range-core and range-edge populations of cane toads (Rhinella marina) due to evolutionary change or developmental plasticity? [PDF]
Royal Society Open Science, 2017 Individuals at the leading edge of expanding biological invasions often show distinctive phenotypic traits, in ways that enhance their ability to disperse rapidly and to function effectively in novel environments.

Graellsia, 2002 La posición taxonómica del sapo andino Bufo poeppigii ha sido objeto de controversia desde su descripción por Tschudi en el siglo XIX. Ello se ha debido a su parecido con Bufo marinus y a que ambas especies pueden encontrarse juntas en algunas ...

Locomotor performance of cane toads differs between native-range and invasive populations [PDF]
Royal Society Open Science, 2017 Invasive species provide a robust opportunity to evaluate how animals deal with novel environmental challenges. Shifts in locomotor performance—and thus the ability to disperse—(and especially, the degree to which it is constrained by thermal and hydric ...

Evolutionary responses to invasion: cane toad sympatric fish show enhanced avoidance learning. [PDF]
PLoS ONE, 2013 The introduced cane toad (Bufo marinus) poses a major threat to biodiversity due to its lifelong toxicity. Several terrestrial native Australian vertebrates are adapting to the cane toad's presence and lab trials have demonstrated that repeated exposure ...

Memorias do Instituto Oswaldo Cruz, 1994 Amblyomma dissimile is a common ectoparasite of cold blooded animals and is an accidental ectoparasite of some wild mammals. Details of the biology of specimens from the State of Amapá were studied in the laboratory in a humidity chamber at an average ...

Divergence in host–parasite interactions during the cane toad's invasion of Australia
Ecology and Evolution, 2022 Coevolutionary host–parasite “arms races” can be disrupted by new evolutionary forces imposed by biological invasions, affecting both host and parasite densities, as well as their traits.

The ontogeny of sexual dimorphism in cane toads (Rhinella marina) [PDF]
Royal Society Open ScienceDetermining an individual’s sex early in life may clarify fundamental issues such as progeny sex ratios and sex-based divergences in ecology and behaviour prior to maturity and be useful in captive breeding of endangered species or in developing methods ...
