Streptozotocin induced hyperglycemia in the axolotl
Developmental Dynamics, EarlyView.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 ...

MALDI-MS argininyl bufadienolide esters fingerprint from parotoid gland secretions of Rhinella arenarum : age, gender and seasonal variation [PDF]
, 2018 In many amphibians, the granular glands can be grouped in special regions forming macroglands. This is the case of toads, characterized by the presence of a pair of parotoid macroglands, strategically located to give protection by poison release in case ...

The effect of trait choice on hybrid species distribution model projections under climate change
Ecography, EarlyView.Species distribution models (SDMs) have been increasingly combined with thermal performance data to enhance their transferability and to provide a physiological explanation for the predicted geographic patterns. Yet, while it is widely acknowledged that thermal sensitivities may vary among biological traits, it remains largely unexplored to what extent

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

Pulmonary vagal modulation of ventilation in toads (Bufo marinus) [PDF]
Respiration Physiology, 2000 This study examined the role of pulmonary vagal feedback on hypercapnic chemosensitivity and breathing pattern formation in cane toads (Bufo marinus). Decerebrate, paralysed toads were uni-directionally ventilated with air, 2.5% CO(2) or 5.0% CO(2) with the lungs inflated or deflated, before and after pulmonary vagotomy.

Detection of Leptospira in cane toads (Rhinella jimi) from urban and rural Paraíba, Brazil
Veterinary Record, EarlyView.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 divergence in morphology and sexual dimorphism of invasive cane toads (Rhinella marina) on Ishigaki Island, Japan [PDF]
Royal Society Open ScienceWhen 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.
