Colour Confusion: Reviewing Ambiguities in the Identification and Classification of Chromatophore Deficiencies Among Amphibians Open
The colour of amphibian skin and eyes (retina and iris) is the result of light interacting with cells called chromatophores, primarily xanthophores, iridophores and melanophores, that can be found in various combinations. Thus, identifying…

Meal or mate: Exploring the evidence of sexual cannibalism among amphibians Open
Active forms of cannibalism that involve predation of live conspecifics occur widely among amphibians, most notably by tadpoles that feed on each other and adults that feed on juveniles. In contrast, cannibalism among amphibian adults (adu…

It's not easy being green: Comparing typical skin colouration among amphibians with colour abnormalities associated with chromatophore deficits Open
Amphibians can obtain their colour from a combination of several different pigment and light reflecting cell types called chromatophores, with defects in one or several of the cells leading to colour abnormalities. There is a need for bett…

The only way is down: placing amphibian ponds on plateaux protects against <i>Gambusia</i> colonization Open
Invasive species pose a significant threat to global biodiversity, prompting the need for novel management strategies. We investigated the effect of pond placement in preventing colonization by Gambusia holbrooki , an invasive fish impacti…

Lovers in strange places: amphibian calling and amplexus detected in tidal mangrove creeks after rainfall Open
Temporary freshwater lenses can form in saline environments after rainfall, providing essential resources for species including drinking water and dispersal routes. However, there is limited indication that these lenses can also be used fo…

Pre‐loved home: Egg clutches of the striped marsh frog, <i>Limnodynastes peronii</i> , detected in water‐filled burrows created by the hunter hairy crayfish, <i>Cherax setosus</i> Open
Many animals create their own microhabitats that are not naturally present in the environment, such as nests and burrows, which are extended phenotypes that perform tasks related to survival and reproduction. Animals may be able to avoid t…

Stuck on you: Wind‐dispersed seeds attach to the external surfaces of a tree frog Open
Many plants exploit the ability of animals to move in order to disperse their pollen and seeds. Despite the growing understanding of the role animals play in the reproductive lives of plants, there are few examples of amphibians contributi…

Don't take my trees: Re‐evaluating the importance of trees when it comes to managing green and golden bell frog, <i>Litoria aurea</i>, habitat Open
It is vital to identify habitats used by each life stage of a species to formulate effective conservation management and restoration guidelines. For the threatened green and golden bell frog, Litoria aurea , it is currently recommended tha…

A little on the nose: A mosquito targets the nostrils of tree frogs for a blood meal Open
As the females of most mosquitoes require a blood meal to provision their eggs, they can be a vector of parasites and pathogens that have profound impacts on both animal and human populations. Understanding the interactions between mosquit…

Moved frogs don’t settle: Evaluating the impact of translocation on the movement behaviour of a threatened frog Open
The deliberate movement of wildlife is an accepted mitigation measure to manage the impact of anthropogenic activities. A presumption is that moved individuals settle at recipient sites that possess appropriate habitat. However, translocat…

Long-Jawed Spider Moves across Water with and without the Use of Silk Open
Among spiders, movement in aquatic environments, including below the water’s surface or on the surface film, is completed using a variety of techniques that do not involve the use of silk, including swimming, walking, and rowing. The use o…

Dragon detectives: citizen science confirms photo-ID as an effective tool for monitoring an endangered reptile Open
Context Among amphibians and reptiles, traditional methods of capture–mark–recapture (CMR) have relied on artificial marking techniques (in particular, toe clipping), which has raised concerns because it may impact climbing ability, surviv…
