A shift in anterior–posterior positional information underlies the fin-to-limb evolution
eLife, 2015 The pectoral fins of ancestral fishes had multiple proximal elements connected to their pectoral girdles. During the fin-to-limb transition, anterior proximal elements were lost and only the most posterior one remained as the humerus.

Mapping Atmospheric Moisture Climatologies across the Conterminous United States
PLOS ONE, 2015 Spatial climate datasets of 1981-2010 long-term mean monthly average dew point and minimum and maximum vapor pressure deficit were developed for the conterminous United States at 30-arcsec (~800m) resolution. Interpolation of long-term averages (twelve monthly values per variable) was performed using PRISM (Parameter-elevation Relationships on ...

Extensive regional atmospheric hydrocarbon pollution in the southwestern United States [PDF]
Proceedings of the National Academy of Sciences, 2003 Light alkane hydrocarbons are present in major quantities in the near-surface atmosphere of Texas, Oklahoma, and Kansas during both autumn and spring seasons. In spring 2002, maximum mixing ratios of ethane [34 parts per 10 9 by volume (ppbv)], propane (20 ppbv), and n -butane (13 ppbv) were ...
