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 ...

Functional morphology of trabecular bone in the calcaneus of African apes

open access: yesJournal of Anatomy, EarlyView.
Pan exhibits significantly higher calcaneal tuberosity trabecular thickness (Tb.Th) and bone volume fraction (BV/TV) than Gorilla, potentially reflecting higher triceps surae forces for vertical climbing. Both taxa have significantly higher Tb.Th and BV/TV in the anterior calcaneus; the difference is exaggerated in Gorilla, potentially reflecting ...

Post‐hatching development of the remote‐tactile bill‐tip organ in precocial shorebirds (Scolopacidae)

open access: yesJournal of Anatomy, EarlyView.
Juvenile scolopacid shorebirds possess well‐developed osteological correlates of tactile bill‐tip organs, indicating sensory systems for remote‐touch foraging are present from early life. Ontogenetic changes in bill‐tip morphology suggest ecological specialisation and interspecific variation develop later, after fledging in these highly precocial ...

Efficiency in the Global Prison System: A Systematic Literature Review and Bibliometric Analysis

open access: yesJournal of Economic Surveys, EarlyView.
ABSTRACT This study systematizes the international literature on prison system efficiency, highlighting patterns and research gaps through a multidimensional framework. By situating efficiency within broader institutional, social, and rights‐based contexts, it examines how academic research has assessed carceral performance.
