Osteohistology of two phorusrhacids reveals uninterrupted growth strategy

The Anatomical Record, EarlyView.
Abstract Phorusrhacidae were apex predators that primarily dominated South America ecosystems for at least 40 million years with their imposing size and predatory lifestyle—yet some aspects of their biology remain poorly understood. Osteohistology is a tool for understanding growth dynamics and biomechanical adaptations.

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

Animal 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

Contrasting properties of predation and scavenging networks governed by megaherbivores in an African savannah

Journal of Animal Ecology, EarlyView.
For the first time, predation and scavenging networks are directly compared within a single ecosystem. Using an 8‐year dataset of African mammals, including megaherbivores, this study reveals distinct structural rules and body mass constraints, providing a scalable framework for studying consumer–resource dynamics and ecosystem function.

A preliminary study on the glycosylation of the reproductive tract in the Ostrich (Struthio camelus camelus)

Reproduction in Domestic Animals, 2020
AbstractGlycosylation of the reproductive tract of an adult female red‐necked ostrich (Struthio camelus camelus) carrying a fully formed calcified egg in her uterus when accidently killed by a blow to the head was examined using lectin histochemistry on samples from the infundibulum, magnum, uterus and vagina.

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

Arabian 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]

Assiut 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.

The Late Agricultural Development of Central Arabian Oases—Archaeobotanical and Archaeozoological Studies of the al‐Kharj Oasis

Arabian Archaeology and Epigraphy, EarlyView.
ABSTRACT While oasis settlements emerged during the Bronze Age in Eastern and Northern Arabia, the settlement process in Central Arabia was different. Excavations at al‐Yamāma—main ancient settlement of the al‐Kharj oasis (Riyadh Province, KSA)—suggest that the latter did not emerge before the second half of the first millennium BCE.

Enterobacteria isolation in ostrich eggs (Struthio Camelus)

Brazilian Journal of Poultry Science, 2012
This study was conducted to determine the presence of enterobacteria in the eggs of ostriches reared on a farm with a history of reproductive failure. Ninety samples from twenty eggs were submitted to bacteriological tests.

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

Journal 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.
