Contrasting patterns of selection between MHC I and II across populations of Humboldt and Magellanic penguins [PDF]

open access: yes, 2016
Indexación: Web of ScienceThe evolutionary and adaptive potential of populations or species facing an emerging infectious disease depends on their genetic diversity in genes, such as the major histocompatibility complex (MHC). In birds, MHC class I deals

W(h)ither Fossils? Studying Morphological Character Evolution in the Age of Molecular Sequences [PDF]

open access: yes, 2008
A major challenge in the post-genomics era will be to integrate molecular sequence data from extant organisms with morphological data from fossil and extant taxa into a single, coherent picture of phylogenetic relationships; only then will these ...

Complete mitochondrial genome sequence of an Australian little penguin (Eudyptula minor novaehollandia, J.R. Forster, 1781)

open access: yesMitochondrial DNA. Part B. Resources, 2017
In this paper, we report the complete mitochondrial genome of an Australian little penguin (Eudyptula minor novaehollandia). The mitogenome sequence has been found to be circular, and 17,608 bp in length. Similar to other Spheniscidae species, the genome
