CALIBRATING DIVERGENCE TIMES ON SPECIES TREES VERSUS GENE TREES: IMPLICATIONS FOR SPECIATION HISTORY OF APHELOCOMA JAYS

Estimates of the timing of divergence are central to testing the underlying causes of speciation. Relaxed molecular clocks and fossil calibration have improved these estimates; ...

Model Misspecification and Probabilistic Tests of Topology: Evidence from Empirical Data Sets

Probabilistic tests of topology offer a powerful means of evaluating competing phylogenetic hypotheses. The performance of the nonparametric Shimodaira-Hasegawa (SH) test, the p...

Temporal analysis of archived samples indicates marked genetic changes in declining North Sea cod (<i>Gadus morhua</i>)

Despite increasing evidence that current exploitation rates can contribute to shifts in life-history traits and the collapse of marine fish stocks, few empirical studies have in...

Large multi-gene phylogenetic trees of the grasses (Poaceae): Progress towards complete tribal and generic level sampling

The Phusion Assembler

The Phusion assembler has assembled the mouse genome from the whole-genome shotgun (WGS) dataset collected by the Mouse Genome Sequencing Consortium, at ∼7.5× sequence coverage,...

Anyone interested in The University of Iowa will enjoy browsing through this storehouse of bibliographic information.Earl Rogers of the University Archives has compiled some 575...

Individual development in a bio-cultural perspective.

Biological and cultural inheritance deeply influence daily human behavior. However, individuals actively interact with bio-cultural information. Throughout their lives, they pre...

States of excellence.

Research from the individual-differences tradition pertinent to the optimal development of exceptional talent is reviewed, using the theory of work adjustment (TWA) to organize ...

Subtle population structuring within a highly vagile marine invertebrate, the veined squid <i>Loligo forbesi</i>, demonstrated with microsatellite DNA markers

Microsatellite DNA markers were applied for the first time in a population genetic study of a cephalopod and compared with previous estimates of genetic differentiation obtained...
