msocc: Fit and analyse computationally efficient multi‐scale occupancy models in R
Christian Stratton, Adam J. Sepulveda, Andrew B. Hoegh
2020, Methods in Ecology and Evolution (11) 1113-1120
Environmental DNA (eDNA) sampling is a promising tool for the detection of rare and cryptic taxa, such as aquatic pathogens, parasites and invasive species. Environmental DNA sampling workflows commonly rely on multi‐stage hierarchical sampling designs that induce complicated dependencies within the data. This complex dependence structure can be intuitively...

2020, Open-File Report 2020-1013
Tribal communities may benefit from land management activities that enhance their use of resources on tribal lands. The Bureau of Indian Affairs is implementing a 5-year vegetation management program to provide support for projects that develop and use natural and cultural resources and improve opportunities for agricultural activities to benefit...
In situ observations of wave transformation and infragravity bore development across reef flats of varying geomorphology
Olivia M. Cheriton, Curt D. Storlazzi, Kurt J. Rosenberger
2020, Frontiers in Marine Science (7)
The character and energetics of infragravity (IG, 25 s 250 s) waves over coral reef flats can enhance shoreline erosion or accretion, and also govern extreme shoreline events such as runup, overwash, and flooding on coral reef-lined coasts. Here...
Selective sediment transport during Hurricane Sandy on Fire Island (New York, USA): Inferences from heavy-mineral assemblages
Joao Cascalho, Pedro Costa, Guy R. Gelfenbaum, SeanPaul La Selle, Bruce E. Jaffe
2020, Journal of Sedimentary Research (90) 269-285
In October 2012, Hurricane Sandy caused severe erosion on beaches and dunes of Fire Island (New York, USA). Major shoreline changes occurred with erosional dominance in the upper shoreline and aggradation in the lowermost section of the beach due to the deposition of eroded upper beach and dune sediment. Sand...
Space use and relative habitat selection for immature green turtles within a Caribbean marine protected area
Lucas P Griffin, Brian J. Smith, Michael Cherkiss, Andrew Crowder, Clayton G Pollock, Zandy Hillis-Starr, Andy J. Danylchuk, Kristen Hart
2020, Animal Biotelemetry (8)
Background A better understanding of sea turtle spatial ecology is critical for the continued conservation of imperiled sea turtles and their habitats. For resource managers to develop the most effective conservation strategies, it is especially important to examine how turtles use and select for habitats within their developmental foraging grounds. Here,...

Peter H. Diaz, Erik L. Orsak, Floyd W. Weckerly, Mike A. Montagne, David A. Alvarez
2020, Journal of Fish and Wildlife Management (11) 287-299
We studied the ecological health of springs experiencing varying levels of urban development to assess impacts to rare endemic salamanders (Eurycea spp.) of Central Texas. We evaluated measures of invertebrate species richness, water quality, and contaminant uptake by salamanders to determine how springs and their inhabitants were being affected by urban...

Rebecca Lazensky, Margaret Hunter, David M. Amador, Basima Al-Khedery, Fahong Yu, Cathy Walsh, Matthew A. Gitzendanner, Katie Tripp, Mike Walsh, Nancy D. Denslow
2020, PLoS ONE (15)
To investigate a Florida manatee (Trichechus manatus latirostris) mortality event following a red tide bloom in Southwest Florida, an RNA sequencing experiment was conducted. Gene expression changes in white blood cells were assessed in manatees rescued from a red tide affected area (n = 4) and a control group (n...

Animals exhibit a diversity of movement tactics [1]. Tracking resources that change across space and time is predicted to be a fundamental driver of animal movement [2]. For example, some migratory ungulates (i.e., hooved mammals) closely track the progression of highly nutritious plant green-up, a phenomenon called “green-wave surfing” [3-5]....
Wildfire-driven changes in hydrology mobilize arsenic and metals from legacy mine waste
Sheila F. Murphy, R. Blaine McCleskey, Deborah A. Martin, JoAnn M. Holloway, Jeffrey H. Writer
2020, Science of the Total Environment (743)
Wildfires burning in watersheds that have been mined and since revegetated pose unique risks to downstream water supplies. A wildfire near Boulder, Colorado that burned a forested watershed recovering from mining disturbance that occurred 80-160 years ago allowed us to 1) assess arsenic and metal contamination in streams draining the...

2020, Science of the Total Environment (743)
Mercury concentrations in freshwater food webs are governed by complex biogeochemical and ecological interactions that spatially vary and are often mediated by climate. The Arctic Coastal Plain of Alaska (ACP) is a heterogeneous, lake-rich landscape where variability in mercury accumulation is poorly understood. Earlier...

Development of a new open-source tool to map burned area and burn severity
Joshua J. Picotte
2020, Conference Paper, Proceedings of the fire continuum- Preparing for the future of wildland fire
Accurate and complete geospatial fire occurrence records are important in determining postfire effects, emissions, hazards, and fuel loading inventories. Currently, the Monitoring Trends in Burn Severity (MTBS) project maps the fire perimeter and burn severity of all large fires on public lands. Although the MTBS project maps a large proportion...
The potential of using dynamic strains in earthquake early warning applications
Noha Sameh Ahmed Farghal, Andrew J Barbour, John Langbein
2020, Seismological Research Letters (91) 2817-2827
We investigate the potential of using borehole strainmeter data from the Network of the Americas (NOTA) and the U.S. Geological Survey networks to estimate earthquake moment magnitudes for earthquake early warning (EEW) applications. We derive an empirical equation relating peak dynamic strain, earthquake moment magnitude, and hypocentral distance, and investigate...
Living on the edge: Multi-scale analyses of bird habitat use in coastal marshes of Barataria Basin, Louisiana, USA
Brett Patton, J. A. Nyman, Megan K. La Peyre
2020, Wetlands (40) 2041-2054
Coastal marsh loss, combined with expected sea-level rise, will cause inundation and extensive shifts to vegetation and salinity regimes that may affect the bird species dependent on coastal ecosystems worldwide. Within coastal marsh habitats, birds provide key targets for coastal management goals. However, limited information on bird-habitat relationships within coastal...
Regionally continuous Miocene rhyolites beneath the eastern Snake River Plain reveal localized flexure at its western margin: Idaho National Laboratory and vicinity
Kyle L. Schusler, David M. Pearson, Michael J. McCurry, Roy C. Bartholomay, Mark H. Anders
2020, The Mountain Geologist (57) 241-270
The eastern Snake River Plain (ESRP) is a northeast-trending topographic basin interpreted to be the result of the time-transgressive track of the North American plate above the Yellowstone hotspot. The track is defined by the age progression of silicic volcanic rocks exposed along the margins of the ESRP. However, the...

Changing disturbance regimes and climate can overcome forest ecosystem resilience. Following high-severity fire, forest recovery may be compromised by lack of tree seed sources, warmer and drier postfire climate, or short-interval reburning. A potential outcome of the loss of resilience is the conversion of the prefire forest to a different...

The U.S. Geological Survey...
Projected climate and land use changes drive plant community composition in agricultural wetlands
Rachel K. Owen, Elisabeth B. Webb, David A. Haukos, Keith W. Goyne
2020, Environmental and Experimental Botany (175) 1-12
Playa wetlands in the Great Plains, USA support a wide variety of plant species not found elsewhere in this agriculturally-dominated region due to the ephemeral presence of standing water and hydric soils within playas. If longer dry periods occur due to climate change or if changes in surrounding land...
