Osmoregulation of the cane toad, Bufo marinus, in salt water [PDF]

open access: yesComparative Biochemistry and Physiology Part A: Physiology, 1985
Adult cane toads, B. marinus, survived in salinities up to 40% sea-water (SW). Pre-exposure to 30, then 40% SW, increased the survival time of toads in 50% SW. Plasma from toads acclimated to salt water is hyperosmotic to the environment--a result of increased plasma sodium, chloride and urea concentrations.

Seroprotein Patterns in the Bufo marinus Complex [PDF]

open access: yes, 2020
The systematic relationships of the large species of neotropical toads of the Bufo marinus complex have not been defined since the studies of Lutz (1925).

Behavioural divergence during biological invasions: a study of cane toads (Rhinella marina) from contrasting environments in Hawai'i [PDF]

open access: yesRoyal Society Open Science, 2018
Invasive species must deal with novel challenges, both from the alien environment and from pressures arising from range expansion per se (e.g. spatial sorting).

Streptozotocin induced hyperglycemia in the axolotl

open access: yesDevelopmental Dynamics, Volume 255, Issue 6, Page 567-584, June 2026.
Abstract Background Diabetes is a group of diseases characterized by loss of β cell mass and/or function, resulting in hyperglycemia. With no established curative treatment, this has initiated research in β cell regeneration. Current animal models have either limited regenerative capacity (mice) or small size and evolutionary distance from humans ...

Rapid divergence in morphology and sexual dimorphism of invasive cane toads (Rhinella marina) on Ishigaki Island, Japan [PDF]

open access: yesRoyal Society Open Science
When a species invades new areas, novel challenges drive rapid shifts in phenotypic traits. Few studies have exploited the opportunity to examine such shifts in replicate invasions of the same species into dissimilar habitats.

Whole System Ecohydrological Change Following Natural Flood Management and a Five‐Year Beaver Reintroduction Trial

open access: yesEcohydrology, Volume 19, Issue 4, June 2026.
ABSTRACT Once‐common beavers have been absent from the British landscape for centuries, but wild beaver populations have returned in recent years as part of reintroduction schemes, including releases into monitored enclosures. In North Yorkshire, such a release of Eurasian beavers took place in 2019.

Whole Body i=In Vivo Vascular Compliance in Two Amphibians, Bufo Marinus and Rana Cate [PDF]

open access: yes, 1997
The mean circulatory filling pressure (MCFP), vascular compliance (C) and unstressed volume (USV) were measured in Bufo marinus and Rana catesbeiana, using an in vivo preparation.

Invasive Colonic Entamoebiasis in Wild Cane Toads, Australia

open access: yesEmerging Infectious Diseases, 2018
We detected a disease syndrome in free-ranging Australian cane toads involving atypical behavior and emaciation that is associated with a previously undescribed Entamoeba sp. that infiltrates the colonic lining, causing it to slough.

Modulation of synaptic vesicle exocytosis in muscle-dependent long-term depression at the amphibian neuromuscular junction. [PDF]

open access: yesPLoS ONE, 2014
We have labeled recycling synaptic vesicles at the somatic Bufo marinus neuromuscular junction with the styryl dye FM2-10 and provide direct evidence for refractoriness of exocytosis associated with a muscle activity-dependent form of long-term ...
