Discovery of Novel Viruses Associated With the Invasive Cane Toad (Rhinella marina) in Its Native and Introduced Ranges [PDF]
Frontiers in Microbiology, 2021 Cane toads (Rhinella marina) are notoriously successful invaders: from 101 individuals brought to Australia in 1935, poisonous toads now cover an area >1.2 million km2 with adverse effects on native fauna.

Chemical cues that attract cannibalistic cane toad (Rhinella marina) larvae to vulnerable embryos [PDF]
Scientific Reports, 2021 Chemical cues produced by late-stage embryos of the cane toad (Rhinella marina) attract older conspecific larvae, which are highly cannibalistic and can consume an entire clutch.

An Efficient Method for the Euthanasia of Cane Toads (Rhinella marina) under Northern Australian Field Conditions [PDF]
Animals, 2021 The euthanasia of cane toads under field conditions presents a number of logistical and animal welfare challenges. One recommended method of control involves the use of carbon dioxide in plastic bags. This paper describes the minimum amount of time (4 h)

Apparent lack of spill-over of parasites from an invasive anuran: PCR detects Entamoeba in cane toads (Rhinella marina) but not in sympatric Australian native frogs [PDF]
International Journal for Parasitology: Parasites and Wildlife, 2020 The recent detection of a novel amoebozoan parasite (Entamoeba sp. CT1) killing invasive cane toads (Rhinella marina) in tropical Australia raises concerns of potential spill-over into native anuran populations.

Arid habitats intensify sexual conflict in invasive cane toads (Rhinella marina) [PDF]
Royal Society Open ScienceAmplexus by male cane toads (Rhinella marina) impairs a female’s mobility and may impose a risk of drowning. Near the arid-zone edge of the toads’ Australian invasion, artificial ponds provide the only permanent open water.

Differences in morphology and in composition and release of parotoid gland secretion in introduced cane toads (Rhinella marina) from established populations in Florida, USA [PDF]
Ecology and Evolution, 2021 Cane toads are highly toxic bufonids invasive in several locations throughout the world. Although physiological changes and effects on native predators for Australian populations have been well documented, Florida populations have received little ...
