Echinoid Associated Traces (EAT)

Elizabeth Petsios, Roger Portell, Shamindri Tennakoon, Tobias Grun, Michal Kowalewski, Lyndsey Farrar & Carrie Tyler
Predation traces found on fossilized prey remains can be used to quantify the evolutionary history of biotic interactions. Fossil mollusk shells bearing these types of traces provided key evidence for the rise of predation during the Mesozoic Marine Revolution (MMR), an event which is thought to have reorganized global marine ecosystems. However, predation pressure on prey groups other than mollusks has not been explored adequately. Consequently, the ubiquity, tempo, and synchronicity of the MMR cannot...

Genome-wide RAD sequencing resolves the evolutionary history of serrate leaf Juniperus and reveals discordance with chloroplast phylogeny

Kathryn Uckele, Robert Adams, Thomas Parchman & Andrea Schwarzbach
Juniper (Juniperus) is an ecologically important conifer genus of the Northern Hemisphere, the members of which are often foundational tree species of arid regions. The serrate leaf margin clade is native to topologically variable regions in North America, where hybridization has likely played a prominent role in their diversification. Here we use a reduced-representation sequencing approach (ddRADseq) to generate a phylogenomic data set for 68 accessions representing all 22 species in the serrate leaf margin...
