Data from: The dynamic role of genetics on cortical patterning during childhood and adolescence

J. Eric Schmitt, Michael C. Neale, Bilqis Fassassi, Javier Perez, Rhoshel K. Lenroot, Elizabeth M. Wells & Jay N. Giedd
Longitudinal imaging and quantitative genetic studies have both provided important insights into the nature of human brain development. In the present study we combine these modalities to obtain dynamic anatomical maps of the genetic contributions to cortical thickness through childhood and adolescence. A total of 1,748 anatomic MRI scans from 792 healthy twins and siblings were studied with up to eight time points per subject. Using genetically informative latent growth curve modeling of 81,924 measures...

Data from: Reduction of the pectoral spine and girdle in domesticated Channel Catfish is likely caused by changes in selection pressure

Michael L. Fine, Shweta Lahiri, Amanda D. H. Sullivan, Mark Mayo, Scott H. Newton & Edward N. Sismour
Locked pectoral spines of the Channel Catfish Ictalurus punctatus more than double the fish’s width and complicate ingestion by gape-limited predators. The spine mates with the pectoral girdle, a robust structure that anchors the spine. This study demonstrates that both spine and girdle exhibit negative allometric growth and that pectoral spines and girdles are lighter in domesticated than in wild Channel Catfish. This finding could be explained by changes in selection pressure for spine growth...

Data from: The gravity of pollination: integrating at-site features into spatial analysis of contemporary pollen movement.

Pollen-mediated gene flow is a major driver of spatial genetic structure in plant populations. Both individual plant characteristics and site-specific features of the landscape can modify the perceived attractiveness of plants to their pollinators and thus play an important role in shaping spatial genetic variation. Most studies of landscape-level genetic connectivity in plants have focused on the effects of inter-individual distance using spatial and increasingly ecological separation; yet have not incorporated individual plant characteristics or...
