Biomechanical modeling of musculoskeletal function related to the terrestrial locomotion of Riojasuchus tenuisceps (Archosauria: Ornithosuchidae)

open access: yesThe Anatomical Record, Volume 308, Issue 2, Page 369-393, February 2025.
Abstract Riojasuchus tenuisceps was a pseudosuchian archosaur from the Late Triassic period in Argentina. Like other ornithosuchids, it had unusual morphology such as a unique “crocodile‐reversed” ankle joint, a lesser trochanter as in dinosaurs and a few other archosaurs, robust vertebrae, and somewhat shortened, gracile forelimbs.

Effects of laying month and length of the storage period on hatchability of ostrich (Struthio camelus) eggs [PDF]

open access: yes, 2014
The effects of laying month and length of the storage period on hatchability of ostrich (Struthio camelus) eggs were studied. A total of 1,740 hatching eggs gathered between April and May from a farm located in the province of Córdoba, Southern Spain ...

Suitability of emu (Dromaius novaehollandiae) eggs for in ovo imaging research as an alternative to conventional animal model: First experience and non‐invasive investigation of physiological embryonal development on computed tomography

open access: yesActa Zoologica, Volume 106, Issue 1, Page 55-64, January 2025.
Abstract Fertilized bird eggs are an alternative model to conventional animal testing. In recent studies, a preclinical imaging model based on large ostrich eggs was introduced in a clinical research centre using imaging systems designed for humans, thus bypassing the need for dedicated small animal imaging systems.

Circulating miRNAome of avian influenza‐infected ruddy turnstones Arenaria interpres

open access: yesJournal of Avian Biology, Volume 2025, Issue 1, January 2025.
MicroRNAs (miRNAs) are highly conserved small noncoding RNAs that regulate gene expression post‐transcriptionally. Circulating miRNAs – miRNAs that have been released from cells and circulate in the bloodstream – are relatively stable and interesting molecules for wildlife research, where they may form a proxy for gene expression as a function of the ...

CONSUMER CHOICE AMONG ALTERNATIVE RED MEATS [PDF]

open access: yes
A multinomial logit model was estimated and used to analyze consumer choice between the best retail meat cut from four species of alternative livestock or "none of these" (all with equal retail prices).

Kiwi forego vison in the guidance of their nocturnal activities [PDF]

open access: yes, 2007
We propose that the Kiwi visual system has undergone adaptive regression evolution driven by the trade-off between the relatively low rate of gain of visual information that is possible at low light levels, and the metabolic costs of extracting that ...
