Gut Health in Ostriches (Struthio camelus): Insights Into Intestinal Structure, Functions, Microbiome, and Improvement Strategies

open access: yesAnimal Research and One Health, EarlyView.
Our paper systematically reviews the intestinal structure, function, and microbiota of ostriches, along with strategies for improving their gut health. We analyze how these factors collectively influence intestinal homeostasis and ostrich welfare, emphasizing probiotics as a promising intervention to enhance gut health, boost population well‐being, and

Bridging the Late Antique Gap in Northwest Arabia: New Archaeological Evidence on the Occupation of Wādī al‐Qurā (al‐ʿUlā [AlUla], Saudi Arabia) Between the Third and Seventh Centuries CE

open access: yesArabian Archaeology and Epigraphy, EarlyView.
ABSTRACT In 2019, the Dadan Archaeological Project (CNRS/RCU/AFALULA) identified a Late Antique village 1 km south of ancient Dadan in the al‐ʿUlā valley (northwest Saudi Arabia). Three excavation seasons at this site (2021–2023) have uncovered a massive building constructed in the late third or early fourth cent.

Causes of mortality among ostriches (Struthio camelus) and emus (Dromaius novaehollandiae) raised commerically in saudi arabia [PDF]

open access: yesAssiut Veterinary Medical Journal, 2008
The incidence and causes of mortality in a mixed ratite farm which produced ostriches and emus were recorded over four production seasons (1998 - 2001). The mean annual mortality rates for ostrich and emu chicks during the rearing phase were 29.1% and 21.

Integrating Indigenous knowledge and modern statistical approaches to model wildlife density based on animal track counts

open access: yesConservation Biology, EarlyView.
Abstract In multiuse areas outside formal protection, sustaining both wildlife and people is critical to wildlife conservation and coexistence efforts. Botswana's Kalahari hosts one of sub‐Saharan Africa’s largest unprotected areas supporting free‐ranging wildlife.

Methane emission by adult ostriches (Struthio camelus)

open access: yesComparative Biochemistry and Physiology Part A: Molecular & Integrative Physiology, 2015
Ostriches (Struthio camelus) are herbivorous birds with a digestive physiology that shares several similarities with that of herbivorous mammals. Previous reports, however, claimed a very low methane emission from ostriches,whichwould be clearly different from mammals.

Layer‐by‐layer soft‐tissue effects on flexion–extension‐dominant passive ex vivo limb joint ROM in quadrupedal mammals: An anatomical contribution to a morphofunctional framework

open access: yesJournal of Anatomy, EarlyView.
Layer‐by‐layer passive ex vivo assessment of flexion–extension‐dominant limb joint ROM across rabbit, pudu deer, chilla fox and pig revealed joint‐, tissue‐ and taxon‐specific responses to progressive tissue removal. Proximal joints often showed increasing ROM, whereas distal joints often showed non‐monotonic responses.

Syrinx anatomy and vocalizations in New World vultures (Aves: Cathartidae): Implications for avian vocal evolution

open access: yesJournal of Anatomy, EarlyView.
New World vultures are the only avian clade proposed to lack a syrinx and have been described as non‐vocal. Using dissection, diceCT, and histology, we demonstrate that cathartid vultures have novel syringeal features that form a syrinx and vocal characterization reveals that they produce more complex vocalizations than previously reported.

Struthio camelus

open access: yes, 2009
STRUTHIO CAMELUS Day 12: This embryo is poorly prepared; however, some general observations are possible. The beak is broad, and the prenasal process does not extend far rostral to the eyes. The distal tip of the prenasal process is directed ventrally. The lower jaw extends only as far as the anterior margin of the orbit.
