Immune-neuroendocrine phenotypic expression changes through life in Coturnix japonica quails

This study examines changes in immune-neuroendocrine profiles (INPs) in quails across life stages, showing shifts toward polarized profiles after stress exposure.

Sex differences in the relationship between maternal and foetal glucocorticoids in a free-ranging large mammal

The paper examines sex differences in the relationship between maternal and fetal glucocorticoids in fallow deer, finding a positive association only in female offspring.

Age and spatio-temporal variations in food resources modulate stress-immunity relationships in three populations of wild roe deer

This study examines how age and environmental food resources affect the relationship between cortisol levels and immune markers in wild roe deer across three populations.

Experimenter familiarization is a crucial prerequisite for assessing behavioral outcomes and reduces stress in mice not only under chronic pain conditions

This study examines how experimenter familiarization affects pain-related behavior and stress in mice with chronic pain, finding it reduces stress but does not significantly alter pain severity.

Effects of more natural housing conditions on the muscular and skeletal characteristics of female C57BL/6J mice

This study examines the effects of different housing conditions on musculoskeletal characteristics and body weight in female C57BL/6J mice, finding that semi-naturalistic environments improve musculoskeletal parameters and reduce stress hormone levels.

Glucocorticoids negatively relate to body mass on the short-term in a free-ranging ungulate

The paper examines the relationship between baseline glucocorticoid levels and body mass in roe deer, finding a negative correlation that persists across different environmental contexts.

Effect of different ambient temperatures on reproductive outcome and wellbeing of lactating females in two mouse strains

This study examines the effects of ambient temperatures on reproductive outcomes and stress hormone levels in two mouse strains during lactation, finding that 30°C impairs reproductive performance but not adrenocortical activity.

Co-variation between glucocorticoids, behaviour and immunity supports the pace-of-life syndrome hypothesis: an experimental approach

The study examines co-variation between glucocorticoids, behaviour, and immunity in roe deer, supporting the pace-of-life syndrome hypothesis.

Stress activity is not predictive of coping style in North American red squirrels

The paper tests if physiological and behavioral stress responses are correlated in wild red squirrels and finds they are independent.

Individual variation in phenotypic plasticity of the stress axis

The paper investigates individual variation in endocrine plasticity of red squirrels in response to fluctuating conspecific density, finding significant individual differences in both mean endocrine phenotype and plasticity.

Experimental increases in glucocorticoids alter function of the HPA axis in wild red squirrels without negatively impacting survival and reproduction

This study shows that experimental increases in cortisol in wild red squirrels alter HPA axis function but do not affect survival or reproduction.
