Whole-genome sequencing projects are increasingly populating the tree of life and
characterizing biodiversity 1 , 2 , 3 – 4 . Sparse taxon sampling has previously been proposed to …

Background There is a high prevalence of blood product transfusions in orthopedic surgery.
The reported prevalence of red blood cell transfusions in unselected patients undergoing …

… These parameters, which are scaled to the neutral mutation rate, μ, include: θ 1 =4N 1 μ, θ
2 =4N 2 μ, θ A =4N A μ, t=tμ, m 1 =m 1 /μ, and m 2 =m 2 /μ. The two migration rates, m 1 and m …

… We were also interested in whether M. fortis, the only obligate follower in clade B, occurred
in the same region. Willson’s (2004) community ecology study of army-ant-following birds in …

A major problem with on-site sanitation is nitrate pollution of the groundwater. A tentative
nitrogen budget is established for pit latrines in eastern Botswana. The ammonia volatilisation …

… Output files were manipulated into the input format required by Migrate (see below) using
a Perl script we wrote. We chose the values of θ to span the extremes of variation observed in …

… For transects T2 and T3, clines for the α D -globin polymorphism were centered at 2,930
m and 485 m asl, and estimated cline widths were 1,446 m and 911 m, respectively. Cline …

Quantifying the role of gene flow during the divergence of closely related species is crucial
to understanding the process of speciation. We collected DNA sequence data from 20 loci (…

… Migration rates were calculated with the migration rate per generation parameter (m sx ×
θ x /4 = M sx ), which is the proportion of individuals in population x that arrived by migration …

Study Design. Prospective observational study. Objective. To investigate the potential
association between fibrinogen, bleeding, and transfusion requirements after scoliosis surgery. …
