Influence of Intramineral Proteins on the Growth of Carbonate Crystals Using as a Scaffold Membranes of Ratite Birds and Crocodiles Eggshells [PDF]

open access: yesMembranes, 2023
The lack of information on structural basis where proteins are involved, as well as the biomineralization processes of different systems such as bones, diatom frustules, and eggshells, have intrigued scientists from different fields for decades.

Egg Incubation Mechanics of Giant Birds [PDF]

open access: yesBiology, 2021
Finite element analysis (FEA) was used to conduct mechanical analyses on eggshells of giant birds, and relate this to the evolution and reproductive behavior of avian species. We aim to (1) investigate mechanical characteristics of eggshell structures of

Brain shapes of large-bodied, flightless ratites (Aves: Palaeognathae) emerge through distinct developmental allometries [PDF]

open access: yesRoyal Society Open Science
Comparative neuroanatomical studies have long debated the role of development in the evolution of novel and disparate brain morphologies. Historically, these studies have emphasized whether evolutionary shifts along conserved or distinct developmental ...

Palaeognath birds innovate to solve a novel foraging problem [PDF]

open access: yesScientific Reports
The ability to innovate implies flexible cognition, and is used as a broad metric of intelligence. Innovation in birds has been intensively studied in the larger and more taxonomically diverse Neognathae clade (particularly crows and parrots) and ...

The Anti-Inflammatory Effect of a γ-Lactone Isolated from Ostrich Oil of Struthio camelus (Ratite) and Its Formulated Nano-Emulsion in Formalin-Induced Paw Edema [PDF]

open access: yesMolecules, 2021
The ostrich oil of Struthio camelus (Ratite) found uses in folk medicine as an anti-inflammatory in eczema and contact dermatitis. The anti-inflammatory effect of a γ-lactone (5-hexyl-3H-furan-2-one) isolated from ostrich oil and its formulated nano ...

The Evolution and Fossil Record of Palaeognathous Birds (Neornithes: Palaeognathae)

open access: yesDiversity, 2022
The extant diversity of the avian clade Palaeognathae is composed of the iconic flightless ratites (ostriches, rheas, kiwi, emus, and cassowaries), and the volant tinamous of Central and South America.

Sex determination in ratite and non ratite birds by molecular method

open access: yesIndian Journal of Animal Sciences, 2016
In spite of number of methods for sex determination in birds, it is very difficult to distinguish sex especially in ratite birds due to lack of sexual dimorphism.
