Single origin of a pan-Pacific bird group and upstream colonization of Australasia

Article Abstract:

Molecular phylogenetic data from a bird family, originally used to justify the simple one-way downstream flow origin of fauna in the Pacific archipelagoes, is used to illustrate that a diverse array of island genera and species are the product of a single-radiation that diversified across major Pacific archipelagos and subsequently settled in continental areas by upstream colonization. Results reveal evolutionary patterns and indicate that the widespread islands are a reason for biodiversity.

A coorelation between the cosmic microwave background and large-scale structure in the Universe

Article Abstract:

The correlations between recent Cosmic Microwave Background (CMB) data and two probes of large-scale structure, the X-ray background and the distribution of radio galaxies, is detected. Reports indicating consistency of correlations with those predicted by dark energy, suggests imprint of dark energy on the growth of structure in the Universe.

Strong population substructure is correlated with morphology and ecology in a migratory bat

Article Abstract:

Research indicates a close correlation of genetic and morphological differentiation in the migratory species bat population substructures. Results show the strong population substructure is accompanied by philopatry in both sexes as determined by nuclear and mitochondrial DNA inheritance patterns.
