Abundance-occupancy patterns of black bass in an impounded river
Leandro E. Miranda
2023, Fisheries Magazine (48) 29-37
A positive relationship has been documented for a wide diversity of taxa between the percentage of transects sampled in which a species is recorded (i.e., occupancy) and the average abundance of the species at transects where recorded. This positive relationship implies that abundance increases faster than occupancy, so populations that...

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, Margaret 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...

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...

Leah Langer, Stephen Beller, Evan Tyler Hirakawa, Jeroen Tromp
2023, Geophysical Journal International (232) 569-580
Earthquakes often occur in regions with complex material structure, such as sedimentary basins or mantle wedges. However, the majority of co-seismic modelling studies assume a simplified, often homogeneous elastic structure in order to expedite the process of model construction and speed up calculations. These co-seismic forward models are used...
