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).

A Review of Theory: Comparing Invasion Ecology and Climate Change‐Induced Range Shifting

open access: yesGlobal Change Biology, Volume 30, Issue 12, December 2024.
We argue that scientists studying either non‐native invasions or climate change‐induced range shifting are interested in the same underlying mechanistic questions: (1) What species traits enable survival in a new location? and (2) Which recipient ecosystems are likely to support a newly arrived species?

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

open access: yesEcosphere, 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.

Field trials of chemical suppression of embryonic cane toads (Rhinella marina) by older conspecifics

open access: yesEcology and Evolution, 2020
Laboratory experiments have shown that the viability of embryos of the invasive cane toad (Rhinella marina) can be reduced by exposure to chemical cues from older conspecific larvae.

Ventilatory behaviors of the toad Bufo marinus revealed by coherence analysis

open access: yesBrazilian Journal of Biology
Breathing in amphibians is a remarkably complex behavior consisting of irregular breaths that may be taken singly or in bouts that are used to deflate and inflate the lungs.
