The Sorcerer II Global Ocean Sampling Expedition: Northwest Atlantic through Eastern Tropical Pacific
TLDR
A metagenomic study of the marine planktonic microbiota in which surface (mostly marine) water samples were analyzed as part of the Sorcerer II Global Ocean Sampling expedition, which yielded an extensive dataset consisting of 7.7 million sequencing reads.
Intraspecific Phylogeography: The Mitochondrial DNA Bridge Between Population Genetics and Systematics
TLDR
This poster presents a probabilistic procedure to characterize the response of the immune system to E.coli bacteria and shows clear patterns in response to the presence of E. coli.
Divergence in proteins, mitochondrial DNA, and reproductive compatibility across the isthmus of Panama.
TLDR
Measurements of biochemical and reproductive divergence for seven closely related, transisthmian pairs of snapping shrimps indicate, however, that isolation was staggered rather than simultaneous, and the four least divergent pairs provide the best estimate for rates of molecular divergence and speciation.
Mitochondrial DNA analysis of Mongolian populations and implications for the origin of New World founders.
TLDR
It is proposed that indigenous populations in east Central Asia represent the closest genetic link between Old and New World populations and is likely that founder effects manifest throughout Asia and the Americas are responsible for differences in mtDNA haplotype frequencies observed in these regions.
Mitochondrial DNA evolution at a turtle's pace: evidence for low genetic variability and reduced microevolutionary rate in the Testudines.
TLDR
Evidence is compiled suggesting a slowdown in mean microevolutionary rate for turtle mitochondrial DNA, and consistency in the direction of the inferred pattern suggests the need for caution in acceptance of a universal mtDNA-clock calibration for higher animals.
Population structure and biogeography of migratory freshwater fishes (Prochilodus: Characiformes) in major South American rivers
TLDR
P phylogenetic analyses showed that each river basin contains a monophyletic group of mtDNA lineages and the branching order places Magdalena in a basal position with subsequent branching of Orinoco, Amazon and Paraná.
Plant DNA barcodes and a community phylogeny of a tropical forest dynamics plot in Panama
TLDR
It is demonstrated that a three-locus DNA barcode when applied to 296 species of woody trees, shrubs, and palms found within the 50-ha Forest Dynamics Plot on Barro Colorado Island, Panama, resulted in >98% correct identifications.
Comparative mtDNA phylogeography of neotropical freshwater fishes: testing shared history to infer the evolutionary landscape of lower Central America
TLDR
The fisheye view of LCA suggests a complex biogeographic history of overlaid cycles of colonization, diversification, sorting and extinction of lineages, a pattern the authors attribute to the continuing development of the landscape due to orogeny and the consequent increase in the insularization of drainage basins.
