Exposure to the Oestrogenic Pollutant 17α‐Ethinyl Estradiol (EE2) Does Not Alter the Behaviour of a Coastal Marine Fish, Cristiceps australis

open access: yesEthology, EarlyView.
Environmental contamination with the synthetic estrogen 17α‐ethinyl estradiol (EE2) is widespread in coastal ecosystems, yet behavioural effects in marine fishes remain poorly understood. We exposed southern crested weedfish (Cristiceps australis) to low and high EE2 concentrations for 14 days and assessed boldness and anxiety using a refuge‐use assay.

Estimation of growth parameters of body weight and body nutrient deposition in males and females of meat- and laying-type quail using the Gompertz model

open access: yesRevista Brasileira de Zootecnia, 2018
The objective of this study was to estimate the growth parameters of body weight and body nutrient deposition in males and females of one meat- (Coturnix coturnix coturnix) and two laying-type quail strains (Coturnix coturnix japonica), designated either

Role of carbon dioxide and ion transport in the formation of sub-embryonic fluid by the blastoderm of the Japanese quail [PDF]

open access: yes, 2002
1. The explanted blastoderm of the Japanese quail was used to explore the role of ions and carbon dioxide in determining the rate of sub-embryonic fluid (SEF) production between 54 and 72 h of incubation. 2.

Courtship display behavior influences tail myology in Centrocercus minimus (Gunnison sage‐grouse)

open access: yesJournal of Anatomy, EarlyView.
Courtship displays among birds are widespread, particularly those which incorporate raised tail feathers for extended periods of time. The Gunnison sage‐grouse (Centrocercus minimus) is such a species. When we compared the tail muscles of the sage‐grouse to birds which do not engage in erected tail fan postures, both morphology proportional mass ...

‘O sibling, where art thou?’ – a review of avian sibling recognition with respect to the mammalian literature [PDF]

open access: yes, 2004
Avian literature on sibling recognition is rare compared to that developed by mammalian researchers. We compare avian and mammalian research on sibling recognition to identify why avian work is rare, how approaches differ and what avian and mammalian ...

Body surface temperatures as biomarkers of physiological environmental adaptation in wild birds and mammals

open access: yesBiological Reviews, Volume 101, Issue 1, Page 336-363, February 2026.
ABSTRACT The ability of individuals to cope with their environment, and therefore the likelihood that they survive and pass on their genes (i.e. fitness), is largely determined by physiological state. Tracking physiological state in wild animals, however, is challenging.

Are biologically meaningful effect sizes a factor in study design? A systematic review of translational chronic variable stress studies

open access: yesExperimental Physiology, Volume 111, Issue 2, Page 349-356, 1 February 2026.
Abstract The design of in vivo studies using laboratory animals is normally guided by the 3Rs: Replacement, Reduction and Refinement. The concept of Reduction is particularly important in the context of estimating sample size; the selected sample size should allow the detection of a predetermined effect size using appropriate statistical tests, but not
