N-terminal domain Increases Activation of Elephant Shark Glucocorticoid and Mineralocorticoid Receptors [PDF]

arXiv, 2019
Cortisol, corticosterone and aldosterone activate full-length glucocorticoid receptor (GR) from elephant shark, a cartilaginous fish belonging to the oldest group of jawed vertebrates. Activation by aldosterone a mineralocorticoid, indicates partial divergence of elephant shark GR from the MR.

Assessing the evidence for treating developmental plasticity and phenotypic flexibility as different phenomena

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Phenotypic plasticity has long played a central role in eco‐evolutionary theory, but it was not until 20 years ago that it was proposed that the term encompasses two distinct phenomena—developmental plasticity and phenotypic flexibility. While this terminology has since

Corticosterone enhances the potency of ethanol against hippocampal long-term potentiation via local neurosteroid synthesis

Frontiers in Cellular Neuroscience, 2015
Corticosterone is known to accumulate in brain after various stressors including alcohol intoxication. Just as severe alcohol intoxication is typically required to impair memory formation only high concentrations of ethanol (60mM) acutely inhibit long ...

A multi‐trait evaluation of patterns and fitness consequences of breeding phenology plasticity with nocturnal warming and food restriction in a lizard

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Faced with climate warming, ectothermic species shift their breeding phenology, which is in part attributed to an acceleration of gestation or incubation in warmer environments.

Early positive tactile stimulation reverses the increase of anxiety and decrease of sociality induced by early chronic mechanical pain in mandarin voles

Integrative Zoology, EarlyView.
This study used a tail‐pinching model during development to simulate mechanical pain experienced by pups in high‐social mandarin voles (Microtus mandarinus). Subsequently, brush‐like positive tactile stimuli were applied to the backs of the mandarin voles.

Bluer in the city: urban male lizards exhibit more intense sexual coloration and lower parasite loads than non‐urban males

Integrative Zoology, EarlyView.
The urban environment may exert different selective pressures on sexually selected traits than more pristine environments. Our study shows that sexual coloration is more saturated (bluer) in male lizards from urban environments than in male non‐urban lizards. The average parasite load is lower in urban lizards than in non‐urban lizards.

Validating the underpinnings of water corticosterone measurement for aquatic amphibians [version 1; peer review: 2 approved]

F1000Research
Background Good animal welfare is important ethically but also to ensure animals provide valid scientific models. Despite thousands of amphibians in research laboratories there is minimal quantitative evidence pertaining to their management and welfare ...

Source population and time spent in captivity affect survival and reproduction of long‐distance translocated northern bobwhites

Animal Conservation, EarlyView.
Long‐distance translocations of northern bobwhites are increasingly used to access source populations with sufficient densities for translocation. This study compared the survival and productivity of bobwhites translocated from the South Texas Plains and the Floridian Coastal Plain to the Floridian Coastal Plain, revealing higher survival and fecundity

Kisspeptin as a test of hypothalamic dysfunction in pubertal and reproductive disorders

Andrology, EarlyView.
Abstract The hypothalamic–pituitary–gonadal axis is regulated by the gonadotropin‐releasing hormone pulse generator in the hypothalamus. This is comprised of neurons that secrete kisspeptin in a pulsatile manner to stimulate the release of GnRH, and, in turn, downstream gonadotropins from the pituitary gland, and subsequently sex steroids and ...

Factors that influence the decision to release rehabilitated koalas (Phascolarctos cinereus) to fire‐affected home sites

Australian Veterinary Journal, EarlyView.
This study appraises recent research to critically evaluate knowledge on the factors that influence decisions around the release of rehabilitated koalas to fire‐affected home sites. Availability of koala release sites could be compromised at times in the future by the increasing incidence of large and intense bushfires due to climate change.
