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

Zoo Biology, Volume 45, Issue 3, Page 300-306, May/June 2026.
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

Zoo 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.

Organic Cation Transporter 3 (OCT3) Is Localized to Intracellular and Surface Membranes in Select Glial and Neuronal Cells Within the Basolateral Amygdaloid Complex of Both Rats and Mice [PDF]

, 2016
Organic cation transporter 3 (OCT3) is a high-capacity, low-affinity transporter that mediates corticosterone-sensitive uptake of monoamines including norepinephrine, epinephrine, dopamine, histamine and serotonin. OCT3 is expressed widely throughout the

Diet, phenology and body size shape nutrient release by songbirds

Functional 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,

Cumulative heatwave stress disrupts thermal homeostasis and plumage structure in a Mediterranean passerine

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Heatwaves are becoming increasingly frequent across the Mediterranean and pose critical challenges for small passerines, yet the physiological and morphological limits to their resilience remain poorly understood.

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

Journal 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.

Stress hormone rapidly tunes synaptic NMDA receptor through membrane dynamics and mineralocorticoid signalling

Scientific Reports, 2017
Stress hormones, such as corticosteroids, modulate the transmission of hippocampal glutamatergic synapses and NMDA receptor (NMDAR)-dependent synaptic plasticity, favouring salient behavioural responses to the environment.

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

Integrative 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‐

Living Low and Dry: Costs of and Resilience to Soil Hydric Stress in a Fossorial Amphisbaenian Reptile

Integrative Zoology, EarlyView.
Soil drought imposes moderate, temporary costs on a strictly fossorial amphisbaenian reptile. However, these animals seem to cope with, at least, moderately short droughts thanks to their peculiar adaptations to living in an underground environment. ABSTRACT The physiological traits of animals can be strongly influenced by climatic fluctuations, and ...

Inhibitory Effect of NMDA Receptors in the Ventral Tegmental Area on Hormonal and Eating Behavior Responses to Stress in Rats

Behavioural Neurology, 2014
Background. Stress and its consequences are among the causes of accidents. Objective. The effects of intraventral tegmental area (I-VTA) memantine on the plasma corticosterone and eating parameters disturbance induced by acute stress were investigated ...
