Using machine learning techniques with incomplete polarity datasets to improve earthquake focal mechanism determination
Robert Skoumal, David R. Shelly, Jeanne L. Hardebeck
2023, Seismological Research Letters (94) 294-304
Earthquake focal mechanisms are traditionally produced using P‐wave first‐motion polarities and commonly require well‐recorded seismicity. A recent approach that is less dependent on high signal‐to‐noise exploits similar waveforms to produce relative polarity measurements between earthquake pairs. Utilizing these relative polarity measurements, it is possible...

Brian D. Healy, Phaedra E. Budy, Charles Yackulic, Brendan P. Murphy, Robert C. Schelly, Mark C. McKinstry
2023, Conservation Biology (37)
Invasive species can dramatically alter ecosystems, but eradication is difficult, and suppression is expensive once they are established. Uncertainties in the potential for expansion and impacts by an invader can lead to delayed and inadequate suppression, allowing for establishment. Metapopulation viability models can aid in planning...
Environmental DNA metabarcoding read numbers and their variability predict species abundance, but weakly in non-dominant species
James Skelton, Allison Cauvin, Maggie Hunter
2023, Environmental DNA (5) 1092-1104
Metabarcoding of environmental DNA (eDNA) provides more comprehensive, efficient, and non-invasive sampling of biological communities than conventional methods. However, limitations of metabarcoding include taxon-specific biases in amplification and sequencing that distort assessments of community composition. Further, hyper-abundant species may disproportionately affect community composition assessments and impair the detection of rare...
Microbial endophytes and compost improve plant growth in two contrasting types of hard rock mining waste
Courtney Creamer, Mary-Catherine Leewis, Francesca C. Governali, John Freeman, Floyd Gray, Emily G. Wright, Andrea L. Foster
2023, International Journal of Phytoremediation (25) 781-788
The re-vegetation of mining wastes with native plants is a comparatively low-cost solution for mine reclamation. However, re-vegetation fails when extreme pH values, low organic matter, or high concentrations of phytotoxic elements inhibit plant establishment and growth. Our aim was to determine whether the combined addition of municipal...
