Evolutionary responses to invasion: cane toad sympatric fish show enhanced avoidance learning. [PDF]

open access: yesPLoS 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 ...

Divergent Selection on Dispersal Targets Chemosensory and Neuronal Genes in Tribolium castaneum. [PDF]

open access: yesMol Ecol
ABSTRACT Dispersal is key to the life history, ecology and evolution of many organisms and important in pest invasiveness. However, the genetic architecture underlying variation in dispersal behaviour remains poorly understood outside of a few model species.

Notes on the biology of Amblyomma dissimile Kock, 1844 (Acari: Ixodida) on Bufo marinus (Linnaeus, 1758) from Brazil

open access: yesMemorias 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

open access: yesEcology 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]

open access: yesRoyal Society Open Science
Determining 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 ...

Natural and experimental infection of the lizard Ameiva ameiva with Hemolivia stellata (Adeleina: Haemogregarinidae) of the toad Bufo marinus

open access: yesParasite, 2007
Developmental stages of a haemogregarine in erythrocytes of the lizard Ameiva ameiva (Teiidae), from Pará State, north Brazil, were shown to be those of Hemolivia by the nature of the parasite’s sporogonic cycle in the tick Amblyomma rotondatum. The type

INNERVATION OF THE LARGE INTESTINE OF THE TOAD (BUFO MARINUS) [PDF]

open access: yesBritish Journal of Pharmacology and Chemotherapy, 1964
The morphology, physiology and pharmacology of the innervation of the toad (Bufo marinus) large intestine have been studied. The large intestine can be divided into the regions colon, rectum and cloaca, on morphological grounds, but acts as a unit in response to nerve stimulation.
