Effects of Simulated Dusk and Dawn on Activity and Feeding of Puerto Rican Crested Toads (Peltophryne lemur) in Captivity

open access: yesZoo Biology, EarlyView.
Puerto Rican crested toads (Peltophryne lemur) that were provided with dim night lights to simulate a natural dusk and dawn moved more frequently than those kept in complete darkness at night. Toads moved more at dusk and dawn than in the middle of the night. ABSTRACT Night light may affect captive amphibians in alternative ways. Captive amphibians may

Finding Mr. Right: Housing Quality Affects Male Mouse Attractiveness to Females, With Implications for Conservation Captive Breeding

open access: yesZoo Biology, EarlyView.
Housing quality affects male mouse attractiveness to females ABSTRACT Females generally prefer mates with traits indicating low stress (e.g., large size; good health). In captivity, stress from suboptimal housing might therefore reduce male attractiveness.

Diet, phenology and body size shape nutrient release by songbirds

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Animals can dramatically alter ecosystem structure and function through the cycling and transport of nutrients in their waste. While birds are particularly capable of influencing nutrient cycles due to their high mobility, abundance, metabolism and functional diversity,

Effects of environmental enrichment on behavioral responses to novelty, learning, and memory, and the circadian rhythm in cortisol in growing pigs [PDF]

open access: yes, 2000
Previously we showed that pigs reared in an enriched environment had higher baseline salivary cortisol concentrations during the light period than pigs reared under barren conditions.

Corticosterone in Commercial Broilers

open access: yesJournal of Applied Poultry Research, 2005
Abstract The welfare of commercially produced broilers is of concern to producers and consumers. When birds are reared under stressful conditions they often exhibit several adaptive responses. The major response is secretion of the stress hormone, corticosterone (CS), by the adrenal glands.

Maternal glucocorticoids have persistent effects on offspring social phenotype irrespective of opportunity for social buffering

open access: yesJournal of Animal Ecology, EarlyView.
This study tests whether early‐life maternal association buffers offspring from the effects of prenatal stress in a facultatively social lizard. Despite clear effects of maternal glucocorticoids on growth and social behaviour, social associations did not mitigate these effects, revealing limits to social buffering in this species.

Consequences of the Lack of IL-10 in Different Endotoxin Effects and its Relationship With Glucocorticoids [PDF]

open access: yes, 2019
Sepsis constitutes one of the major causes of death in ICUs. In sepsis induced by gram-negative, although lipopolysaccharide (LPS) initially induces an exacerbated secretion of proinflammatory cytokines leading to endotoxic shock and death resembling a ...

Sex‐Specific Involvement of Gut Microbiota in Behavioral and Endocrine Responses to Chronic Predator Odor in Brandt's Voles

open access: yesIntegrative Zoology, EarlyView.
18 days of predator odor exposure altered gut microbiota, increased anxiety‐like behaviors, and elevated hypothalamic–pituitary–adrenal axis activity in Brandt's voles, with males showing behavioral habituation and females remaining sensitive. Cecal microbiota transplantation experiments confirmed that only female recipients of microbiota from predator‐
