Laid-back invaders: Cane toads (Rhinella marina) down-regulate their stress responses as they colonize a harsh climate

Global Ecology and Conservation, 2020
In response to encountering abiotic extremes, many organisms exhibit stress responses as measured by levels of corticosterone and heat-shock protein (e.g., HSP70) in the blood. Such responses can enhance organismal viability.

Resting respiratory behavior in minimally instrumented toads - effects of very long apneas on blood gases and pH

Brazilian Journal of Biology, 2003
Resting respiratory behavior of Bufo marinus in minimally instrumented toads is described for a period of 24 hours in which the animals are left undisturbed.

Pest control by the public: Impact of hand-collecting on the abundance and demography of cane toads (Rhinella marina) at their southern invasion front in Australia

Global Ecology and Conservation, 2020
The population dynamics of an alien species can be heterogeneous across a geographically widespread invasion– and thus, the effectiveness of alternative control methods can vary.

A biological invasion impacts ecosystem services: cane toads change the rate of scavenging and the suite of scavengers

Ecosphere, 2021
By affecting the abundance of key native species, invasive taxa may disrupt ecosystem services. In Australia, large monitor lizards (Varanus spp.) play critical roles as scavengers and apex predators.

Is “cooling then freezing” a humane way to kill amphibians and reptiles?

Biology Open, 2015
What is the most humane way to kill amphibians and small reptiles that are used in research? Historically, such animals were often killed by cooling followed by freezing, but this method was outlawed by ethics committees because of concerns that ice ...

Host–parasite interactions during a biological invasion: The fate of lungworms (Rhabdias spp.) inside native and novel anuran hosts

International Journal for Parasitology: Parasites and Wildlife, 2015
The cane toad invasion in Australia provides a robust opportunity to clarify the infection process in co-evolved versus de novo host–parasite interactions.

Pheromones can cull an invasive amphibian without releasing survivors from intraspecific competition

Ecosphere, 2019
Attempts to cull an invasive species often create a paradoxical situation, whereby the consequent reduction in invader densities frees the survivors from intraspecific competition—and hence, increases the viability of those survivors.
