Frontiers in Zoology, 2012 Background The avian glottis channels air from the oropharynx to the trachea and is situated on an elevated structure, the laryngeal mound. It is imperative that the glottis be protected and closed during swallowing, which in mammals is achieved by ...

Avian Lifespan Network Reveals Shared Mechanisms and New Key Players in Animal Longevity
Aging Cell, Volume 24, Issue 9, September 2025.In this work, we found that birds with similar lifespans exhibit convergent evolution in specific genes, suggesting that shared evolutionary pressures shape the genetic basis of lifespan similarity across species. By investigating protein–protein interactions across genes evolving convergently in long‐ and short‐lived species, we identified a network ...

Characterization of Chicken Tumor Necrosis Factor-α, a Long Missed Cytokine in Birds
Frontiers in Immunology, 2018 Tumor necrosis factor-α (TNF-α) is a pleiotropic cytokine playing critical roles in host defense and acute and chronic inflammation. It has been described in fish, amphibians, and mammals but was considered to be absent in the avian genomes.

Contrasting morphological evidence for the presence of taste buds in Dromaius novaehollandiae and Struthio camelus (Palaeognathae, Aves) [PDF]
Zoomorphology, 2015 This study, facilitated by the use of immunohistochemistry, indicated the presence of taste buds in Dromaius novaehollandiae but not in Struthio camelus. Seen at the light microscope level, the taste buds consisted of follicular cells and receptor cells.

Molecular Ecology, Volume 34, Issue 15, August 2025.Abstract Colour signals play pivotal roles in different communication systems, and the evolution of these characters has been associated with behavioural ecology, integumentary production processes and perceptual mechanisms of the species involved. Here, we present the first insight into the molecular and histological basis of skin colour polymorphism ...

A focus on females can improve science and conservation
Ibis, Volume 167, Issue 3, Page 819-827, July 2025.As a field, ecology has historically misunderstood or overlooked female organisms, or assumed that they are ‘similar enough’ to males. The typical unit of study for ecology research stops at the species level, but that can be too coarse and can obscure important intraspecific differences.

Ecology and Evolution, Volume 15, Issue 5, May 2025.We have developed a new, quantitative method of assessing the variation on paleosurfaces. This method uses functions from the molaR package of R, including new functions detailed here. This paper tests the functions on the eggshell surfaces of extant emu (Dromaius novaehollandiae) and fossil oviraptorosaur eggs of the ootaxon Macroelongatoolithus ...
