At the invasion front, male cane toads (Rhinella marina) have smaller testes. [PDF]
Biol Lett, 2019 As a colonizing species expands its range, individuals at the invasion front experience different evolutionary pressures than do those at the range-core. For example, low densities at the edge of the range mean that males should rarely experience intense sperm competition from rivals; and investment into reproduction may trade-off with adaptations for ...

Using genetic data to predict the vulnerability of a native predator to a toxic invader [PDF]
, 2016 Australia has no native toad species, and as a consequence, many Australian predators lack resistance to the toxins of the invasive cane toad Rhinella marina, and die if they ingest one of these toads.

Uncovering the antimalarial potential of toad venoms through a bioassay-guided fractionation process
International Journal for Parasitology: Drugs and Drug Resistance, 2022 Malaria remains to date one of the most devastating parasitic diseases worldwide. The fight against this disease is rendered more difficult by the emergence and spread of drug-resistant strains. The need for new therapeutic candidates is now greater than

Behavioural flexibility allows an invasive vertebrate to survive in a semi-arid environment [PDF]
, 2014 Plasticity or evolution in behavioural responses are key attributes of successful animal invasions. In northern Australia, the invasive cane toad (Rhinella marina) recently invaded semi-arid regions. Here, cane toads endure repeated daily bouts of severe

Artificial water points facilitate the spread of an invasive vertebrate in arid Australia [PDF]
, 2014 Summary: The spread of invasive species after their initial introduction is often facilitated by human actions. In some cases, invaders only become established in habitats where dominant native species have been displaced as a result of human actions or ...

Anuran artifacts of preservation: 27 years later [PDF]
, 2009 Measurements made on preserved anuran specimens are often used in studies of systematics, ecology and evolution. Here, we examine the effect of preservation on one of the most common measurement of frogs, snout-urostyle length (SUL).

Behavioural responses of reptile predators to invasive cane toads in tropical Australia [PDF]
, 2013 The ecological impact of an invasive species can depend on the behavioural responses of native fauna to the invader. For example, the greatest risk posed by invasive cane toads (Rhinella marinaBufonidae) in tropical Australia is lethal poisoning of ...

Evaluation of antimutagenic and cytotoxic activity of skin secretion extract of Rhinella marina and Rhaebo guttatus (Anura, Bufonidae) [PDF]
Acta Amazonica, 2019 The skin secretion from toads of the Bufonidae family has great potential in the search for new active compounds to be used as drug candidates in treating some diseases, among them cancer.
