Decoupling the Roles of Corticosterone in Mediating Effects of Methylmercury and Chytrid Fungus (Bd) on Amphibian Survival 解构皮质酮在介导甲基汞与壶菌 (Bd) 对两栖动物生存影响中的双重作用

open access: yesWildlife Letters, EarlyView.
Effects of methylmercury bioaccumulation on survival of Columbia Spotted Frogs were modified by sex and length and were mediated by corticosterone (a glucocorticoid hormone) whereas effects of chytrid fungus were limited. ABSTRACT Amphibians have suffered widespread declines caused by many interacting factors whose effects are often difficult to ...

The Effects of Human Presence, Restraint, and Stressed Neighbors on Corticosterone Levels in Domesticated Budgerigars (Melopsittacus undulatus)

open access: yesZoo Biology, EarlyView.
Female budgerigars (Melopsittacus undulatus) did not significantly elevate their plasma corticosterone levels in response to human presence at the beginning of the experiment. However, plasma corticosterone was significantly elevated by restraint stress, the return of a neighbor that received restraint stress, and human presence at the end of the ...

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

open access: yesFunctional 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.

Mate desertion affects offspring survival, development and physiology in a songbird with multiple parental strategies

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Sexual conflict affects the amount and duration of offspring care each parent invests, resulting in multiple parental care strategies sometimes coexisting within a single population.

Thyroid thermogenesis in adult rat hepatocytes in primary monolayer culture: direct action of thyroid hormone in vitro. [PDF]

open access: yes, 1979
We have studied the effect of 3,5,3'-triiodothyronine (T3) on the respiration of adult rat hepatocytes in primary monolayer culture prepared from hypothyroid rat liver. After addition of T3 to the culture medium at a concentration of 2 x 10(-7) M, oxygen

Does nocturnal light pollution impair immune function in a wild‐living amphibian?

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Light pollution is among the most rapidly growing anthropogenic stressors on Earth. As it spreads far beyond its original source, it affects natural protected areas playing a key role in protecting biodiversity.

Early handling and repeated cross-fostering have opposite effect on mouse emotionality [PDF]

open access: yes, 2015
Early life events have a crucial role in programming the individual phenotype and exposure to traumatic experiences during infancy can increase later risk for a variety of neuropsychiatric conditions, including mood and anxiety disorders.
