Post-Early Miocene silicic volcanism in the northern Mojave Desert, California
David M. Miller, Phillip B Gans, Tracey J. Felger, Jorge A. Vazquez
2022, Conference Paper, Volcanoes in the Mojave: 2022 Desert symposium field guide and proceedings
Silicic volcanism that postdates widespread early Miocene volcanism in the Mojave Desert is underappreciated. We compiled age, petrographic, and geochemical data for volcanic rocks in a wide swath of the desert south of the Garlock fault using an age threshold of post-18.8 Ma, approximately the limit of the earlier Miocene...

Bloater, Coregonus hoyi, are deepwater planktivores native to the Laurentian Great Lakes and Lake Nipigon. Interpretations of commercial fishery time series suggest they were common in Lake Ontario through the early 1900s but by the 1950s were no longer captured by commercial fishers. Annual bottom trawl surveys that...
Biomarkers in the Precambrian: Earth’s ancient sedimentary record of life
Christian Hallmann, Katherine L. French, Jochen J. Brocks
2022, Elements (18) 93-99
The hydrocarbon remnants of biologically diagnostic lipids inform our understanding of Earth’s early ecosystems, particularly where morphological vestiges of biology are absent or ambiguous. Yet both the analysis and interpretation of ancient biomarkers require scrutinous approaches. Here, we describe the status quo of...
The ~400 yr B.P. eruption of Half Cone, a post-caldera composite cone within Aniakchak caldera, Alaska Peninsula
Brandon Browne, Christina A. Neal, Charles R. Bacon
2022, Report
Aniakchak volcano is a historically active caldera located on the central Alaska Peninsula. The largest eruption from Aniakchak since the ~3,400 yr B.P. caldera-forming eruption occurred ~400 yr B.P. from Half Cone volcano, an intracaldera composite cone on the northwest floor of the Aniakchak caldera that was largely destroyed by the eruption. The ~400...
Elevating human dimensions of amphibian and reptile conservation, a USA perspective
Deanna H. Olson, David S. Pilliod
2022, Conservation Science and Practice (4)
Increasing threats to amphibian and reptile species raise the urgency of their conservation. However, relative to other vertebrate groups at risk, amphibians and reptiles have low and more variable social capital; they are not generally high-priority natural goods and services valued by people. Consequently, relative to...

Prior to the Perseverance rover landing, the acoustic environment of Mars was unknown. Models predicted that: (i) atmospheric turbulence changes at centimeter scales or smaller at the point where molecular viscosity converts kinetic energy into heat1, (ii) the speed of sound varies at the surface with frequency2,3, and (iii) high...
Post-fledging spatial dispersion and movement behaviour differs between cavity-nesting and open-cup nesting passerines
Necmiye Sahin Arslan, Thomas E. Martin
2022, Ibis (164) 486-493
Spatial dispersion and movement behaviour vary across animal taxa and can affect fitness. The reasons why species differ in movement behaviour of young and why some species form family groups and other species have dispersed young have been rarely addressed. We tested a hypothesis that spatial dispersion and movement behaviour...
Estimating soil moisture, actual evapotranspiration, climatic water deficit, and groundwater recharge during periods of drought for current and future climate conditions in Hawaiʻi
Alan Mair, Delwyn S. Oki
2022, Report
Mid- and end-of-century climate projections for the Hawaiian Islands indicate that rainfall is projected to decrease across large areas. In areas affected by drought or where the future climate becomes drier, reduced groundwater recharge can affect freshwater availability. Reduced rainfall can also reduce soil moisture, which can increase the risk...

2022, Journal of Applied Ecology (59) 1536-1547
Many large mammalian carnivores are facing population declines due to illegal killing (e.g., shooting) and habitat modification (e.g., livestock farming). Illegal killing occurs cryptically and hence is difficult to detect. However, reducing illegal killing requires a solid understanding of its magnitude and underlying drivers, while accounting for the imperfect...
A flexible movement model for partially migrating species
Elizabeth Eisenhauer, Ephraim M. Hanks, Matthew Beckman, Robert Murphy, Tricia A. Miller, Todd E. Katzner
2022, Spatial Statistics (50)
We propose a flexible model for a partially migrating species, which we demonstrate using yearly paths for golden eagles (Aquila chrysaetos). Our model relies on a smoothly time-varying potential surface defined by a number of attractors. We compare our proposed approach using varying coefficients to a latent-state model, which...
Pesticide exposure of wild bees and honey bees foraging from field border flowers in intensively managed agriculture areas
Laura T. Ward, Michelle L. Hladik, Aidee Guzman, Sara Winsemius, Ariana Bautista, Claire Kremen, Nicholas Mills
2022, Science of the Total Environment (831)
Bees are critical for food crop pollination, yet their populations are declining as agricultural practices intensify. Pollinator-attractive field border plantings (e.g. hedgerows and forb strips) can increase bee diversity and abundance in agricultural areas, however recent studies suggest these plants may contain pesticides. Pesticide exposure for wild bees in agricultural...
Evaluation of MPA designs that protect highly mobile megafauna now and under climate change scenarios
Morgan Elizabeth Gilmour, Josh Adams, Barbara A. Block, Jennifer E. Caselle, A. M. Friedlander, Edward T. Game, E. L. Hazen, Nick D. Holmes, Kevin D. Lafferty, S. M. Maxwell, Douglas J. McCauley, E. M. Oleson, Kenneth H. Pollock, S. A. Shaffer, N. H. Wolff, Alex Wegmann
2022, Global Ecology and Conservation (35)
Marine protected area (MPA) designs, including large-scale MPAs (LSMPAs; >150,000 km2), mobile MPAs (fluid spatiotemporal boundaries), and MPA networks, may offer different benefits to species and could enhance protection by encompassing spatiotemporal scales of animal movement. We sought to understand how well LSMPAs could benefit nine highly-mobile marine species in the tropics...

Brian J. Halstead, Andrew M. Ray, Erin L. Muths, Evan H. Campbell Grant, Rob Grasso, Michael J. Adams, Kathleen Semple Delaney, Jane Carlson, Blake R. Hossack
2022, Ecological Indicators (136)
Protected areas like national parks are essential elements of conservation because they limit human influence on the landscape, which protects biodiversity and ecosystem function. The role of national parks in conservation, however, often goes far beyond limiting human influence. The U.S. National Park Service and its system of land units...
Vulnerability of avian populations to renewable energy production
Tara Conkling, Hannah B. Vander Zanden, Taber D Allison, James E. Diffendorfer, Thomas V Dietsch, A. Duerr, Amy L Fesnock, Rebecca R. Hernandez, S. R. Loss, David M. Nelson, Peter M. Sanzenbacher, Julie L. Yee, Todd E. Katzner
2022, Royal Society Open Science (9)
Renewable energy production can kill individual birds, but little is known about how it affects avian populations. We assessed the vulnerability of populations for 23 priority bird species killed at wind and solar facilities in California, USA. Bayesian hierarchical models suggested that 48% of these species were vulnerable to population-level...
