The Effects of the Toxic Cyanobacterium Limnothrix (Strain AC0243) on Bufo marinus Larvae [PDF]

Toxins, 2014
Limnothrix (strain AC0243) is a cyanobacterium, which has only recently been identified as toxin producing. Under laboratory conditions, Bufo marinus larvae were exposed to 100,000 cells mL−1 of Limnothrix (strain AC0243) live cultures for seven days ...

Larval Adaptation to Salinity Shock in Cane Toads (Rhinella marina) From Coastal French Guiana [PDF]

Ecology and Evolution
Many habitats not only differ in mean conditions but also in the degree to which these conditions fluctuate through time. Therefore, local adaptation to both mean abiotic conditions and habitat variability can enhance organismal viability.

Tadpole Skin Secretions, Not Food or Temperature, Mediate Costly Cannibal‐Induced Plasticity in Invasive Cane Toad Hatchlings [PDF]

Ecology and Evolution
Hatchlings of invasive cane toads (Rhinella marina) in Australia respond facultatively to chemical cues of non‐feeding cannibalistic conspecific tadpoles by accelerating development, but consequently experience reduced growth, development and survival in

Measuring energetics and behaviour using accelerometry in cane toads Bufo marinus. [PDF]

PLoS ONE, 2010
Cane toads Bufo marinus were introduced to Australia as a control agent but now have a rapidly progressing invasion front and damage new habitats they enter. Predictive models that can give expansion rates as functions of energy supply and feeding ground

Detection of Leptospira in cane toads (Rhinella jimi) from urban and rural Paraíba, Brazil. [PDF]

Vet Rec
Abstract Background Leptospirosis is a significant zoonosis in tropical regions, where poor sanitation and favourable climate aid its spread. Synanthropic animals such as the cane toad (Rhinella jimi), which share environments with both people and wild and domestic animals, may harbour Leptospira and contribute to urban and rural transmission cycles ...

Rapid geographic divergence in competitive ability of cane toad larvae (Rhinella marina) during a biological invasion. [PDF]

Ecology
Abstract Low population densities at the expanding edge of a biological invasion are predicted to reduce intraspecific competition such that invading organisms evolve to prioritize adaptations for rapid rates of population growth and dispersal over those that facilitate success in competitive interactions.

Divergent Selection on Dispersal Targets Chemosensory and Neuronal Genes in Tribolium castaneum. [PDF]

Mol Ecol
ABSTRACT Dispersal is key to the life history, ecology and evolution of many organisms and important in pest invasiveness. However, the genetic architecture underlying variation in dispersal behaviour remains poorly understood outside of a few model species.

slc26a12-A novel member of the slc26 family, is located in tandem with slc26a2 in coelacanths, amphibians, reptiles, and birds. [PDF]

Physiol Rep
Abstract Solute carrier family 26 (Slc26) is a family of anion exchangers with 11 members in mammals (named Slc26a1‐a11). Here, we identified a novel member of the slc26 family, slc26a12, located in tandem with slc26a2 in the genomes of several vertebrate lineages.

Intraspecific interference retards growth and development of cane toad tadpoles, but those effects disappear by the time of metamorphosis

Royal Society Open Science, 2023
Competition among larval anurans can occur via interference as well as via a reduction in per-capita food supply. Previous research on intraspecific interference competition in cane toad (Rhinella marina) tadpoles found conflicting results, with one ...

Assessment of virally vectored autoimmunity as a biocontrol strategy for cane toads. [PDF]

PLoS ONE, 2011
BACKGROUND: The cane toad, Bufo (Chaunus) marinus, is one of the most notorious vertebrate pests introduced into Australia over the last 200 years and, so far, efforts to identify a naturally occurring B. marinus-specific pathogen for use as a biological
