DIFFERENCES IN HETEROCHROMATIN BETWEEN SOME AVIAN SPECIES

The Histological Differences of the Ureter in Japanese Quail (Coturnix japonica) Compared With Some Other Domestic Avian Species

The aim of this investigation was to determine the histological differences of anatomical regions of the ureter in Japanese quail compared with some other domestic avian species such as pigeon, European starling and fowl. Tissue samples from proximal, middle and distal regions of each ureter were obtained and stained with H & E, Alcian blue (pH 2.5), Periodic acid-Schiff, Masson’s trichrome, Ve...

Species delimitation in systematics: inferring diagnostic differences between species.

Species are fundamental units in studies of systematics, biodiversity and ecology, but their delimitation has been relatively neglected methodologically. Species are typically circumscribed based on the presence of fixed (intraspecifically invariant or non-overlapping) diagnostic morphological characters which distinguish them from other species. In this paper, we argue that determining whether...

Species-specific Relative Ahr1 Binding Affinities of 2,3,4,7,8- 1 Pentachlorodibenzofuran Explain Avian Species Differences in Its

Molecular phylogeny of some avian species using Cytochrome b gene sequence analysis

Veritable identification and differentiation of avian species is a vital step in conservative, taxonomic, forensic, legal and other ornithological interventions. Therefore, this study involved the application of molecular approach to identify some avian species i.e. Chicken (Gallus gallus), Muskovy duck (Cairina moschata), Japanese quail (Coturnix japonica), Laughing dove (Streptopelia senegale...

Some Interesting Differences between Verbs and Nouns

Verbs are different from;nouns in ways that go beyond chair syntactic privileges . Verbs are harder to remember, more broadly defined, more prone to be altered in meaning when conflict of meaning occurs, less stable in translation between languages, and slower to be acquired by children than nouns . In this paper I argue that the differences stem in part from a basic cognitive distinction that,...
