Six decades of seismology at South Pole, Antarctica: Current limitations and future opportunities to facilitate new geophysical observations
Robert Anthony, Adam T. Ringler, M. DuVernois, K. Anderson, David C. Wilson
2021, Seismological Research Letters (92) 2718-2735
Seismograms from the South Pole have been important for seismological observations for over six decades by providing (until 2007) the only continuous seismic records from the interior of the Antarctic continent. The South Pole, Antarctica station has undergone many updates over the years, including conversion...
Supporting the development and use of native plant materials for restoration on the Colorado Plateau (Fiscal Year 2020 Report)
Robert Massatti, Daniel E. Winkler, Sasha C. Reed, Michael C. Duniway, Seth M. Munson, John B. Bradford
2021, Report
A primary focus of the Colorado Plateau Native Plant Program (CPNPP) is to identify and develop appropriate native plant materials (NPMs) for current and future restoration projects. Multiple efforts have characterized the myriad challenges inherent in providing appropriate seed resources to enable effective, widespread restoration and have identified a broad...
Long-term salinity change and growth of the harmful alga, Prymnesium parvum
Emily T. Richardson, Reynaldo Patino
2021, Journal of Phycology (57) 1335-1344
Prymnesium parvum is a euryhaline, toxin-producing microalga. Although its abundance in inland waters and growth potential in the laboratory is reduced at high salinity (>20), the ability of inland strains to adjust their growth after long-term residence in high salinity is uncertain. An inland strain of P. parvum maintained at salinity of 5 in...

Sean B. Smith, Phillip J. van Mantgem, Dennis Odion
2021, Natural Resource Report NPS/KLMN/NRR—2021/2236
The Klamath Network of the National Park Service consists of six park units located in northern California and southern Oregon. The Network began implementing a vegetation monitoring protocol in 2011 to identify ecologically significant vegetation trends in the parks. The premise of the protocol is that multivariate analyses of species...

Marine fish movement plays a critical role in ecosystem functioning and is increasingly studied with acoustic telemetry. Traditionally, this research has focused on single species and small spatial scales. However, integrated tracking networks, such as the Integrated Tracking of Aquatic Animals in the Gulf of Mexico (iTAG) network, are building...
Angler-caught salmonid diets illustrate Lake Ontario Alewife population and predator-prey dynamics
Brian Weidel, Scott P. Minihkeim, Michael Connerton, Christopher Legard, Nicholas Farese, Christopher Osborne, Jana Lantry
2021, Report
Lake Ontario fisheries decision makers use information about the status and trajectory of prey fish populations, such as alewife, for salmonid sport fish management. In 2020, the April bottom trawl survey, typically used to assess alewife, was canceled the day after it began due to Coronavirus health concerns. This prompted...

2021, Herpetological Review (52) 29-39
Pathogens and their associated diseases have the potential to severely affect wildlife populations, including herpetofauna. Concern is increasing for transmission pathways of herpetofaunal diseases, especially for amphibians affected by the fungal pathogens Batrachochytrium dendrobatidis (Bd: Longcore et al. 1999) and B. salamandrivorans (Bsal: Martel et al. 2013), and amphibians and...

2021, Remote Sensing (13)
Declines in riparian ecosystem greenness and water use have been observed in the delta of the Lower Colorado River (LCR) since 2000. The purpose of our case study was to measure these metrics on the U.S. side of the border between Hoover and Morelos Dams to see...
Relative energy production determines effect of repowering on wildlife mortality at wind energy facilities
Manuela Huso, Tara Conkling, Daniel Dalthorp, Melanie J Davis, Heath Smith, Amy Fesnock-Parker, Todd E. Katzner
2021, Journal of Appllied Ecology (58) 1284-1290
Reduction in wildlife mortality is often cited as a potential advantage to repowering wind facilities, that is, replacing smaller, lower capacity, closely spaced turbines, with larger, higher capacity ones, more widely spaced. Wildlife mortality rates, however, are affected by more than just size and spacing of turbines, varying with...
Regional ensemble modeling reduces uncertainty for digital soil mapping
Colby C. Brungard, Travis W. Nauman, Michael C. Duniway, Kari E. Veblen, Kyle C. Nehring, David S. White, Shawn W. Salley, Julius Anchang
2021, Geoderma (397)
Recent country and continental-scale digital soil mapping efforts have used a single model to predict soil properties across large regions. However, different ecophysiographic regions within large-extent areas are likely to have different soil-landscape relationships so models built specifically for these regions may more accurately capture these relationships relative to...

Biological correlates of sea urchin recruitment in kelp forest and urchin barren habitats
Ben Weitzman, Brenda H. Konar
2021, Marine Ecology Progress Series (663) 115-125
Shifts between the alternate stable states of sea urchin barren grounds and kelp forests correspond to sea urchin density. In the Aleutian Archipelago, green sea urchins Strongylocentrotus polyacanthus are the dominant herbivores that graze kelp forests. Sea urchin recruitment is an important driver that influences sea urchin density, particularly in the absence...

Range-wide greater sage-grouse hierarchical monitoring framework—Implications for defining population boundaries, trend estimation, and a targeted annual warning system
Peter S. Coates, Brian G. Prochazka, Michael S. O’Donnell, Cameron L. Aldridge, David R. Edmunds, Adrian P. Monroe, Mark A. Ricca, Gregory T. Wann, Steve E. Hanser, Lief A. Wiechman, Michael P. Chenaille
2021, Open-File Report 2020-1154
Incorporating spatial and temporal scales into greater sage-grouse (Centrocercus urophasianus) population monitoring strategies is challenging and rarely implemented. Sage-grouse populations experience fluctuations in abundance that lead to temporal oscillations, making trend estimation difficult. Accounting for stochasticity is critical to reliably estimate population trends and investigate variation related to deterministic factors...
A rock record of complex aeolian bedforms in a Hesperian desert landscape: The Stimson formation as exposed in the Murray Buttes, Gale Crater, Mars

2021, Journal of Geophysical Research - Planets (126)
Lithified aeolian strata encode information about ancient planetary surface processes and the climate during deposition. Decoding these strata provides insight regarding past sediment transport processes, bedform kinematics, depositional landscape, and the prevailing climate. Deciphering these signatures requires a detailed analysis of sedimentary architecture to reconstruct dune morphology, motion, and the...
