Ungulate reproductive parameters track satellite observations of plant phenology across latitude and climatological regimes
David Stoner, Joseph O. Sexton, Jyoteshwar Nagol, Heather H. Bernales, Thomas C. Edwards Jr.
2016, PLoS ONE (11) 1-19
The effect of climatically-driven plant phenology on mammalian reproduction is one key to predicting species-specific demographic responses to climate change. Large ungulates face their greatest energetic demands from the later stages of pregnancy through weaning, and so in seasonal environments parturition dates should match periods of high primary productivity. Interannual...

Constraints on the source parameters of low-frequency earthquakes on the San Andreas Fault
Amanda M. Thomas, Gregory C. Beroza, David R. Shelly
2016, Geophysical Research Letters (43) 1464-1471
Low-frequency earthquakes (LFEs) are small repeating earthquakes that occur in conjunction with deep slow slip. Like typical earthquakes, LFEs are thought to represent shear slip on crustal faults, but when compared to earthquakes of the same magnitude, LFEs are depleted in high-frequency content and have lower corner frequencies, implying longer...

James D. Muirhead, Alexa R. Van Eaton, Giuseppe Re, James D. L. White, Michael H. Ort
2016, Bulletin of Volcanology (78) 1-16
Although monogenetic volcanic fields pose hazards to major cities worldwide, their shallow magma feeders (<500 m depth) are rarely exposed and, therefore, poorly understood. Here, we investigate exposures of dikes and sills in the Hopi Buttes volcanic field, Arizona, to shed light on the nature of its magma feeder system. Shallow...
