Senior Geology major Opal Perron-Feller is co-author in Current Biology

Lamsdell, J. C., V. E. McCoy, Opal A. Perron-Feller, and M. J. Hopkins. 2020. Air Breathing in an Exceptionally Preserved 340-Million-Year-Old Sea Scorpion. Current Biology 30:4316-+.

From the abstract: 

"Arachnids are the second most successful terrestrial animal group after insects and were one of the first arthropod clades to successfully invade land. Fossil evidence for this transition is limited, with the majority of arachnid clades first appearing in the terrestrial fossil record. Furthermore, molecular clock dating has suggested a Cambrian-Ordovician terrestrialization event for arachnids, some 60 Ma before their first fossils in the Silurian, although these estimates assume that arachnids evolved from a fully aquatic ancestor. ... Here, we present details of the respiratory organs of Adelophthalmus pyrrhae sp. nov. from the Carboniferous of Montagne Noire, France, revealed through micro computed tomography (m-CT) imaging. ... The discovery of air-breathing structures in eurypterids indicates that characters permitting terrestrialization accrued in the arachnid stem lineage and suggests the Cambrian-Ordovician ancestor of arachnids would also have been semi-terrestrial."  Published by Cell Press, online at Elsevier's ScienceDirect.com.

Michael Moore Publishes in Gene, with Collaborators at Hainan Univ, China


 Wang, J., Moore, Michael J., Wang, H., Zhu, Z., & Wang, H. (2021). Plastome evolution and phylogenetic relationships among Malvaceae subfamilies. Gene, 765, 145103. 10.1016/j.gene.2020.145103

From the abstract: "Malvaceae s.l. is the largest family of Malvales, comprising more than 4225 species. Within Malvaceae, the phylogenetic relationships among subfamilies remain controversial. To resolve these relationships and explore plastome evolution in Malvaceae, we assembled a complete plastome data set of 39 Malvales species, including newly reported sequences for 13 Malvaceae and two Dipterocarpaceae species. ...Phylogenetic reconstructions based on 78 protein-coding genes strongly supported nearly all relationships among Malvaceae subfamilies. The diversification of the subfamilies of Malvaceae was dated to the late Cretaceous and early Eocene, during a time of global warmth."

Malvaceae, also known as the mallow family, includes Hibiscus, okra, cotton, and cacao.  More from Britannica.com.

Matthew Elrod publishes in ACS Earth and Space Chemistry

journal cover
Matthew Elrod, Robert and Eleanor Biggs Professor of Natural Science and Professor of Chemistry and Biochemistry, co-authored this paper with three currently enrolled students: senior Erika Aoki, junior Jon Sarrimanolis, and junior Sophie Lyon.

Aoki, E., Sarrimanolis, J. N., Lyon, S. A., & Elrod, M. J. (2020). Determining the relative reactivity of sulfate, bisulfate, and organosulfates with epoxides on secondary organic aerosol. ACS Earth and Space Chemistry, 4(10), 1793-1801. 10.1021/acsearthspacechem.Oc00178

From the abstract: "The relative reactivities (nucleophilic strengths relative to water) of sulfate, bisulfate, and methyl sulfate anion were measured through a series of model epoxide-nucleophile experiments using nuclear magnetic resonance (NMR) spectroscopy."

This is a relatively new journal from the American Chemical Society.  From an editorial in the first issue, published in 2017:  "The launch of ACS Earth and Space Chemistry presents an opportunity to deepen and expand the conversation about the integral role that chemistry plays in the study of fundamental and applied research in the fields of geology, astronomy, oceanography, and atmospheric science."
