International Journal for Parasitology: Parasites and Wildlife, 2014 A new species of coccidian (Protozoa: Apicomplexa: Eimeriidae) obtained from rheas, Rhea americana, is reported in Brazil. Oocysts of Isospora rheae sp. nov. are spherical to subspheroidal, measuring 22.6 × 21.0 µm, and have a double and smooth wall that

The complete mitochondrial genome of Psammomys obesus (Rodentia: Muridae)
Mitochondrial DNA. Part B. Resources, 2018 The fat sand rats (Psammomys obesus) can easily induce obesity and acquire type 2 diabetes mellitus when they are fed with high-carbohydrate diets. P. obesus is often used as an animal model for studies on diabetes and obesity.

Cardiac morphological and morphometric analysis of Ardea alba
The Anatomical Record, EarlyView.Abstract Ardea alba (Linnaeus, 1758) is a widely distributed heron species whose cardiovascular morphology remains poorly described. This study aimed to characterize the cardiac morphology and morphometry of adult A. alba. Ten specimens were analyzed using radiographic, morphometric, histological, scanning electron microscopy, and three‐dimensional ...

Morphology of the tongue of the emu (Dromaius novaehollandiae). II. Histological features
Onderstepoort Journal of Veterinary Research, 2009 Although a number of brief, fragmented descriptions have been provided on the gross morphology of the ratite tongue, very few studies have documented the histological structure of this organ.

Exceptional preservation informs the paleobiology of tapinocephalid dinocephalians
The Anatomical Record, EarlyView.Abstract The tapinocephalid dinocephalian Moschops is one of the most iconic taxa of the middle Permian, yet its paleobiology remains one of the least well‐known. Here, we address some aspects of paleoneurology and paleobiology of Moschops using CT scanning of four well preserved skulls from the upper Abrahamskraal Formation of South Africa. Two of the

Journal of Anatomy, EarlyView.Sternum morphology varies among birds and is a function of body mass and order. The area of the sternum is inversely related to the area of the keel suggesting that the increase in bone mass associated with a large keel has been mitigated by a reduction in bone mass of the sternum.

Ancient DNA analyses reveal contrasting phylogeographic patterns amongst kiwi (Apteryx spp.) and a recently extinct lineage of spotted kiwi. [PDF]
PLoS ONE, 2012 The little spotted kiwi (Apteryx owenii) is a flightless ratite formerly found throughout New Zealand but now greatly reduced in distribution. Previous phylogeographic studies of the related brown kiwi (A. mantelli, A. rowi and A.

Journal of Morphology, Volume 287, Issue 8, August 2026.Integration of detailed hindlimb anatomy with biomechanical analyses demonstrates that pedal performance in the red‐and‐green macaw is driven by specialized muscle architecture and force distribution. Hypertrophy of digit IV flexor musculature, together with modifications of the intrinsic and extensor muscles, enhances grasping stability, climbing, and

Broad-scale recombination pattern in the primitive bird Rhea americana (Ratites, Palaeognathae). [PDF]
PLoS ONE, 2017 Birds have genomic and chromosomal features that make them an attractive group to analyze the evolution of recombination rate and the distribution of crossing over.

Austral Ecology, Volume 51, Issue 6, June 2026.ABSTRACT Presently, there are three main hypotheses to explain why the leaves of many Australian mistletoes resemble their hosts. The eco‐physiological convergence hypothesis suggests that mistletoes must manage their physiology, especially their water relations, to match those of the host, to avoid killing themselves or the host branch they have ...
