Ancient DNA Reveals Late Pleistocene Existence of Ostriches in Indian Sub-Continent.

open access: yesPLoS ONE, 2017
Ancient DNA (aDNA) analysis of extinct ratite species is of considerable interest as it provides important insights into their origin, evolution, paleogeographical distribution and vicariant speciation in congruence with continental drift theory. In this

Evaluation of the Impact of Alginate Coating Infused With Nanoemulsified Eryngium Campestre Essential Oil on the Physicochemical and Microbial Quality of Ostrich Thigh Meat

open access: yesJournal of Food Processing and Preservation, Volume 2026, Issue 1, 2026.
The aim of this study was to evaluate the impact of a sodium alginate (SA) coating incorporating Eryngium campestre (zulang) essential oil (EO) nanoemulsion (EON) regarding the preservation characteristics of ostrich meat under cold storage condition. The primary constituents of the EO were germacrene D, α‐bisabolol, campestrolide, and salvial‐4(14)‐en‐

Metabolismo oxidativo de heterófilos de avestruzes jovens Oxidative metabolism by heterophils from young ostriches

open access: yesCiência Rural, 2009
Foi avaliada a hipótese que, à semelhança dos neutrófilos de mamíferos, a produção de superóxido pelos heterófilos de avestruzes está associada com a maturidade funcional dessas células. Foram utilizados 20 avestruzes de ambos os sexos, divididos em dois

The island syndrome in plants on New Zealand's outlying islands: a review

open access: yesNew Zealand Journal of Botany, Volume 63, Issue 5, Page 2300-2324, December 2025.
ABSTRACT The island syndrome is defined as a suite of predictable and consistent differences between island and mainland organisms. In seed plants, much of what we know about the island syndrome comes from work in the Southwest Pacific, which is comprised of the three main islands of New Zealand and ten surrounding archipelagos.
