Peering into the world of wild passerines with 3D‐SOCS: Synchronized video capture and posture estimation

open access: yesMethods in Ecology and Evolution, Volume 17, Issue 2, Page 339-356, February 2026.
Abstract Collection of large behavioural data‐sets on wild animals in natural habitats is vital in ecology and evolution studies. Recent progress in machine learning and computer vision, combined with inexpensive microcomputers, has unlocked a new frontier of fine‐scale markerless measurements.

Pendulous Crop in Japanese Quail (Coturnix coturnix japonica)

open access: yesPoultry Science, 1974
Abstract Quail chicks from a line selected for growth on a low protein (17.9%) glucose monohydrate-soybean meal diet showed a high incidence, 44.0%, of pendulous crop as compared to 11.8% in the control line fed the same ration. Substituting sucrose for glucose monohydrate did not change the incidence of pendulous crop in either the control or the ...

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
