The effect of stress changes on time-dependent earthquake probabilities for the central Wasatch Fault Zone, Utah, USA
A. Verdecchia, S. Carena, B. Pace, Christopher DuRoss
2019, Geophysical Journal International (219) 1065-1081
Static and quasi-static Coulomb stress changes produced by large earthquakes can modify the probability of occurrence of subsequent events on neighboring faults. This approach is based on physical (Coulomb stress changes) and statistical (probability calculations) models, which are influenced by the quality and quantity of data available in the study...
Water-level data for the Albuquerque Basin and adjacent areas, central New Mexico, period of record through September 30, 2018
Andre B. Ritchie, Amy E. Galanter
2019, Data Series 1116
The Albuquerque Basin, located in central New Mexico, is about 100 miles long and 25–40 miles wide. The basin is hydrologically defined as the extent of consolidated and unconsolidated deposits of Tertiary and Quaternary age that encompasses the structural Rio Grande Rift between San Acacia to the south and Cochiti...
Alongshore momentum balance over shoreface-connected ridges, Fire Island, NY
Conor Ofsthun, Xiaodong Wu, George Voulgaris, John C. Warner
2019, Continental Shelf Research (186) 21-33
Hydrodynamic and hydrographic data collected on the inner shelf of Fire Island, NY, over a region of shoreface-connected ridges (SFCRs) are used to describe wind-driven circulation over uneven topographies along relatively straight coastlines. The data revealed a predominantly alongshore flow, under westward wind forcing, with localized offshore current veering over...
Using a Bayesian network to understand the importance of coastal storms and undeveloped landscapes for the creation and maintenance of early successional habitat
Sara L. Zeigler, Benjamin T. Gutierrez, Emily J. Sturdivant, Daniel H. Catlin, James D. Fraser, A. Hecht, Sarah M. Karpanty, Nathaniel G. Plant, E. Robert Thieler
2019, PLoS ONE (14)
Coastal storms have consequences for human lives and infrastructure but also create important early successional habitats for myriad species. For example, storm-induced overwash creates nesting habitat for shorebirds like piping plovers (Charadrius melodus). We examined how piping plover habitat extent and location changed on barrier islands in New York, New...

Henehan, Brett Metcalfe, Isabel Fenton, Bridget Wade, Lyndsey Fox, Julie Meilland, Catherine V. Davis, Ulrike Baranowski, Jeroen Groeneveld, Kirsty M. Edgar, Aurore Movellan, Tracy Aze, Harry J. Dowsett, Giles Miller, Nelson Rios, Pincelli M. Hull
2019, Paleoceanography and Paleoclimatology (34) 1157-1177
Accurate planktonic foraminiferal species identification is central to many paleoceanographic studies, from selecting specific species for geochemical research to elucidating the biotic dynamics of microfossil communities relevant to physical oceanographic processes and interconnected phenomena such as climate change. However, species identification varies among taxonomic schools, few resources exist to train...
The importance of simulation assumptions when evaluating detectability in population models
Adrian P. Monroe, Gregory T. Wann, Cameron L. Aldridge, Peter S. Coates
2019, Ecosphere (10)
Population monitoring is important for investigating a variety of ecological questions, and N-mixture models are increasingly used to model population size (N) and trends (lambda) while estimating detectability (p) from repeated counts within primary periods (when populations are closed to changes). Extending these models to dynamic processes with serial dependence...

Sean Parks, Lisa M. Holsinger, Michael J. Koontz, Luke S. Collins, Ellen Whitman, Marc-Andre Parisien, Rachel A. Loehman, Jennifer L. Barnes, Jean-Francois Bourdon, Jonathan Boucher, Yan Boucher, Anthony C. Caprio, Adam Collingwood, Ron Hall, Jane Park, Lisa Saperstein, Charlotte Smetanka, Rebecca J. Smith, Nick Soverel
2019, Remote Sensing (11)
Satellite-derived spectral indices such as the relativized burn ratio (RBR) allow fire severity maps to be produced in a relatively straightforward manner across multiple fires and broad spatial extents. These indices often have strong relationships with field-based measurements of fire severity, thereby justifying their widespread use in management and science....

The use of continuous water-quality time-series data to compute nutrient loadings for selected Iowa streams, 2008–17
Jessica D. Garrett
2019, Scientific Investigations Report 2019-5054
In support of nutrient reduction efforts, nitrate (as nitrate plus nitrite) and phosphorus loads and yields were computed for selected streams in Iowa based on continuously monitored sensor data for 2008–17 and 2014–17, respectively. Sample data were used to assess nitrate sensor bias and to create phosphorus-turbidity surrogate models. Where...
Bayesian statistics for beginners: A step-by-step approach
Therese M. Donovan, Ruth M. Mickey
2019, Book
Bayesian statistics is currently undergoing something of a renaissance. At its heart is a method of statistical inference in which Bayes' theorem is used to update the probability for a hypothesis as more evidence or information becomes available. It is an approach that is ideally suited to making initial assessments...

2019, International Journal of Climatology (10)
The North American Monsoon (NAM) delivers precipitation to the southwestern USA during the warm-dry summer season. The seasonal extent of NAM precipitation is highly variable and is likely to change under future climate change. Our objective was to determine how large scale monsoonal patterns as well as local variables influence...
Long-term (37 years) impacts of low-head dams on freshwater shrimp habitat connectivity in northeastern Puerto Rico
Jessica Chappell, S. Kyle McKay, Mary Freeman, Catherine M. Pringle
2019, River Research and Applications (35) 1034-1043
Freshwater migratory shrimp in Puerto Rico depend on watershed connectivity, from stream headwaters to the ocean, to complete their life cycle. Moreover, shrimp populations in different watersheds are known to be connected in an island-wide metapopulation. However, low-head dams paired with water intakes on streams draining the El Yunque National...

2019, Conservation Biology (34) 482-493
Population viability analysis (PVA) is a powerful conservation tool, but one that remains unapproachable for many species. This is particularly true for species with multiple, broadly-distributed populations for which collecting suitable data can be challenging. A recently-developed method of multiple population viability analysis (MPVA), however, addresses many limitations...
Spatial capture-recapture reveals age- and sex-specific survival and movement in stream amphibians
R. Ken Honeycutt, Justin M Garwood, Winsor H. Lowe, Blake R. Hossack
2019, Oecologia (190) 821-833
Life history information sets the foundation for our understanding of ecology and conservation requirements. For many species, this information is lacking even for basic demographic rates such as survival and movement. When survival and movement estimates are available, they are often derived from mixed demographic groups and do not consider...
