Escherichia coli is classified as a rod-shaped, Gram-negative bacterium in the family Enterobacteriaceae. The bacterium mainly inhabits the lower intestinal tract of warm-blooded animals, including humans, and is often discharged into the environment through feces or wastewater effluent. The presence of E. coli in environmental waters has long been considered...
Voluminous arc dacites as amphibole reaction-boundary liquids
Dawnika L. Blatter, Thomas W. Sisson, William B. Hankins
2017, Contributions to Mineralogy and Petrology (172) 1-37
Dacites dominate the large-volume, explosive eruptions in magmatic arcs, and compositionally similar granodiorites and tonalites constitute the bulk of convergent margin batholiths. Shallow, pre-eruptive storage conditions are well known for many dacitic arc magmas through melt inclusions, Fe–Ti oxides, and experiments, but their potential origins deeper in the crust are...

Josephine D’Urban Jackson, Natalie dos Remedios, Kathryn Maher, Sama Zefania, Susan M. Haig, Sara J. Oyler-McCance, Donald Blomqvist, Terry Burke, Michael W. Bruford, Tamas Szekely, Clemens Kupper
2017, Evolution (71) 1313-1326
Sexual selection may act as a promotor of speciation since divergent mate choice and competition for mates can rapidly lead to reproductive isolation. Alternatively, sexual selection may also retard speciation since polygamous individuals can access additional mates by increased breeding dispersal. High breeding dispersal should hence increase gene flow and...
Is biotic resistance enhanced by natural variation in diversity?
James B. Grace, Susan P. Harrison, Howard Cornell
2017, Oikos (126) 1484-1492
Theories linking diversity to ecosystem function have been challenged by the widespread observation of more exotic species in more diverse native communities. Few studies have addressed the underlying processes by dissecting how biotic resistance to new invaders may be shaped by the same environmental influences that determine diversity and other...

Alice E. Alpert, Anne L. Cohen, Delia W. Oppo, Thomas M. DeCarlo, Glenn A. Gaetani, Edwin A. Hernandez-Delgado, Amos Winter, Meagan Gonneea Eagle
2017, Paleoceanography (32) 146-160
Coral skeletons are valuable archives of past ocean conditions. However, interpretation of coral paleotemperature records is confounded by uncertainties associated with single-element ratio thermometers, including Sr/Ca. A new approach, Sr-U, uses U/Ca to constrain the influence of Rayleigh fractionation on Sr/Ca. Here we build on the initial Pacific Porites Sr-U...
