Nudds, R. L. and Slove Davidson, J. 2010. A shortening of the manus precedes the attenuation of other wing‐bone elements in the evolution of flightlessness in birds. —Acta Zoologica (Stockholm) 91: 115–122
This is the first study to present evidence for a general pattern of wing‐bone attenuation during the early stages of the evolution of flightlessness. A comparative analysis using phylogenetic independent...
This investigation aimed to determine the morphological characteristics of the tongue, palate and laryngeal entrance of southern lapwing by gross anatomy and scanning electron microscopy. For this purpose, the organs of three birds were used as material. Numerous densely distributed acicular projections were found on the lingual apex. Papillary crest consisting of sharp conical papillae were observed...
The vascular endothelial growth factor (VEGF) family belong to the platelet‐derived growth factor supergene family and is involved in angiogenesis and mitogenesis. The VEGF–VEGFR system regulates endothelial cell proliferation, migration, vascular permeability, secretion and other non‐endothelial cells functions. To clarify the possible role of endothelial and non‐endothelial cells, VEGF and its receptors,...
