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

open access: yesGlobal 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

open access: yesEcosphere, 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?

open access: yesBiology 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 ...

Long‐Term Declines in Body Size of the Invasive Rusty Crayfish (Faxonius rusticus) in Temperate Lakes

open access: yesFreshwater Biology, Volume 70, Issue 1, January 2025.
ABSTRACT Invasive species often experience phenotypic change during the invasion process. For example, many invasive species are larger in their non‐native than native ranges, but some invasive species experience body size declines with time since invasion.

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

open access: yesInternational 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.

Ophthalmic findings and parameters in Western tiger salamanders (Ambystoma mavortium) from northern Colorado

open access: yesVeterinary Ophthalmology, Volume 28, Issue 1, Page 9-20, January 2025.
Abstract Objective The aim of this study was to document ophthalmic examination findings and provide reference values for ocular examinations and diagnostics in clinically normal Western tiger salamanders (Ambystoma mavortium) and to evaluate the mydriatic effect of a topical rocuronium bromide and identify any adverse effects.

Live Fast, Die Young: Life History Traits of an Apex Predator Exacerbate the Ecological Impact of a Toxic Invader

open access: yesEcology and Evolution, Volume 14, Issue 12, December 2024.
We show that large floodplain monitors reach sexual maturity surprisingly rapidly, and females rarely live for more than 2 years. This fast life history requires novel reproductive strategies and high feeding rates, favouring the evolution of “risky” tactics such as consuming novel prey items (such as invasive toxic cane toads).
