The combined effects of tectonism and volcanism had major environmental implications in the Quaternary evolution of the Cauca River causing unprecedented damming of a one of the major torrential tropical rivers in northern South America.
In this study we describe for the first time a comprehensive evolution of the lesions caused by M. tuberculosis in a large animal that might fit the traditional view of control of this infection in humans, which leads to an LTBI.
MLST alleles reflect slow evolution of the genome caused by point mutations and selective pressure.
We can assume that a superinfection developed in these subjects rather than an evolution of the strain caused by drug-selection pressure.
Differences in parasite species and its immunomodulatory properties on the vertebrate host cells impact the outcome of infection, as observed in the evolution of the infection caused by L. (L).
Rather, historical events have led to the evolution of proximate causes of the migratory behaviour by selecting for heritable variation that predisposes birds to respond to appropriate cues with migration.
KVG performed the phylogenetic analysis, detection of positive selection, analysis of protein evolution, suggested the causes for positive selection events.
What does whether birds are migratory or non-migratory have to do with the evolution of the parasite that causes avian malaria?
Replicate populations of natural and experimental organisms often show evidence of parallel genetic evolution, but the causes are unclear.
Furthermore, by using ancillary data obtained from in-situ and ground-based observations, we investigate the origin and the evolution of the ionospheric irregularities causing scintillations, reconstructing the ionospheric background in which such irregularities formed and moved.
