Spontaneous diseases in captive ratites (Struthioniformes) in northwestern Germany: A retrospective study

PLoS ONE, 2017
A retrospective study was carried out to define the spectrum of spontaneous diseases in ostriches and few other captive ratites, order Struthioniformes, in northwestern Germany. The investigation included 71 ratites necropsied between 1968 and 2014. They

ENHYDROSS: A New Mechanistic Model Supports the Trans-Oceanic Dispersal Capability of Terrestrial Vertebrates. [PDF]

Ecol Evol
We introduce ENHYDROSS, a new mechanistic model that uses optimal swimming speed and minimum cost of transport to estimate maximum dispersal distances and durations for vertebrates, enabling assessment of long‐distance oceanic dispersal potential. Applied to a range of extant and extinct animals, the model's estimates generally align with observed data;

Evolution of bird sex chromosomes: a cytogenomic approach in Palaeognathae species [PDF]

BMC Ecology and Evolution
Background Different patterns of sex chromosome differentiation are seen in Palaeognathae birds, a lineage that includes the ratites (Struthioniformes, Rheiformes, Apterygiformes, Casuariiformes, and the sister group Tinamiformes).

Wildlife Pathogens and Zoonotic Disease Risk Assessment in Vietnam: A Wildlife Trade Hotspot. [PDF]

Transbound Emerg Dis
Vietnam is a wildlife trade hotspot presenting multiple high‐risk interfaces for pathogen spillover from wildlife to humans. However, the zoonotic disease risk remains poorly characterized in the country and needs to be assessed to better inform policy dialog and legislative reforms.

Density and abundance of Rhea pennata garleppi (Struthioniformes: Rheidae) in the Puna ecoregion of Argentina [PDF]

Revista Chilena de Historia Natural, 2014
Rhea pennata is classified internationally as a near-threatened species, with the subspecies R. p. garleppi being listed as endangered. The aim of this study was to provide updated information on the density and abundance of R. p. garleppi in the southern Puna ecoregion of Argentina. Density was estimated indirectly on the basis of monthly feces counts

Palaeognathae: Apterygiformes, Casuariiformes, Rheiformes, Struthioniformes; Tinamiformes

, 2018
The infraclass Palaeognathae includes the flightless ratites (ostrich, emu, rhea, cassowary, kiwi) and the tinamous, a group of related, flighted birds. This chapter focuses on unique anatomy and important non-infectious and infectious diseases of these groups of birds.

The Importance of Olfaction for Mixed Paternity in Birds. [PDF]

Ecol Evol
Olfaction can help individuals finding genetically compatible mates in many animals, while high levels of mixed paternity may reflect a reduced ability to evaluate a mate's profile against their own before mating. We tested this hypothesis by matching estimates of olfactory ability with mixed paternity for a broad range of bird species.
