Morphology of the extraocular muscles (m. bulbi) in the pre-hatchling and post-hatchling african black ostriches (struthio camelus domesticus L., 1758) (Aves: Struthioniformes) [PDF]

Acta Biologica Hungarica, 2018
The aim of the study was to describe the morphology and the development of the extraocular muscles (EOMs) in the pre-hatchling and post-hatchling African black ostrich. The study involved 50 birds aged between 28 days and 3 years. The EOMs were analyzed morphologically with respect to the location and length of the straight and oblique muscles and the ...

Morphological study of the upper, lower and third eyelids in the African black ostrich (Struthio camelus camelusL., 1758) (Aves: Struthioniformes) during the embryonic and postnatal period [PDF]

Italian Journal of Zoology, 2016
AbstractThe upper, lower and third eyelids are accessory organs of the eye. The aim of this study was to describe the development of the upper, lower and third eyelids in ostriches in the embryonic and postnatal period and to characterise the conjunctiva-associated lymphoid tissue (CALT) in the eyelids.

Diversity in olfactory bulb size in birds reflects allometry, ecology, and phylogeny [PDF]

, 2015
The relative size of olfactory bulbs (OBs) is correlated with olfactory capabilities across vertebrates and is widely used to assess the relative importance of olfaction to a species’ ecology.

Inter-vertebral flexibility of the ostrich neck:implications for estimating sauropod neck flexibility [PDF]

, 2013
The flexibility and posture of the neck in sauropod dinosaurs has long been contentious. Improved constraints on sauropod neck function will have major implications for what we know of their foraging strategies, ecology and overall biology.
