Multiscale habitat factors explain variability in stream fish occurrence in the Ozark Highlands ecoregion, USA
Robert Mollenhauer, Yan Zhou, Shannon K. Brewer
2019, Copeia (107) 219-231
The dynamic, multiscale nature of stream systems makes it challenging to establish basic ecological principles to guide stream fish conservation and management. For example, finer-scale instream habitat is often constrained by coarser-scale characteristics driving observed species distributions. Additionally, instream environmental variability can result in patchy species distributions within general upstream–downstream...

Aluminum mobility in mildly acidic mine drainage: Interactions between hydrobasaluminite, silica and trace metals from the nano to the meso-scale
Manuel A. Caraballo, Richard Wanty, Philip Verplanck, Leonardo Navarro-Valdivia, Carlos Ayora, Michael Hochella
2019, Chemical Geology (519) 1-10
Aluminum precipitates control the hydrochemistry and mineralogy of a broad variety of environments on Earth (e.g., acid mine drainage, AMD, coastal wetlands, boreal and alpine streams, tropical acid sulfate soils, laterites and bauxites, …). However, the geochemical and mineralogical processes controlling Al (and other associated metals and metalloids) transport and removal in those environments...

John R Reinfelder, Sarah E. Janssen
2019, Journal of Hazardous Materials (375) 121-129
Spatial redistribution of legacy mercury (Hg) contamination in the Hackensack River estuary (New Jersey, USA) was evaluated using mercury stable isotopes. Total Hg varied from 0.06 to 3.8 µg g-1 in sediment from the tidal Hackensack River and from 15 to 154 µg g-1 near historically contaminated sites in...

Matthew Vaughan, William B. Bowden, James B. Shanley, Andrew W. Vermilyea, Andrew W. Schroth
2019, Biogeochemistry (143) 275-291
The quantity and character of dissolved organic matter (DOM) can change rapidly during storm events, affecting key biogeochemical processes, carbon bioavailability, metal pollutant transport, and disinfection byproduct formation during drinking water treatment. We used in situ ultraviolet–visible spectrophotometers to concurrently measure dissolved organic carbon (DOC) concentration...
Temporal and abiotic fluctuations may be preventing successful rehabilitation of soil-stabilizing biocrust communities
Kristina E. Young, Matthew A. Bowker, Sasha C. Reed, Michael C. Duniway, Jayne Belnap
2019, Ecological Applications (29)
Land degradation is a persistent ecological problem in many arid and semi-arid systems globally (drylands hereafter). Most instances of dryland degradation include some form of soil disturbance and/or soil erosion, which can hinder vegetation establishment and reduce ecosystem productivity. To combat soil erosion, researchers have identified a need...

2019, Book chapter, Ecosystem consequences of soil warming: Microbes, vegetation, fauna and soil biogeochemistry
The tropics are a region encircling the equator, delineated to the north by the Tropic of Cancer (23°26′14.0″N) and to the south by the Tropic of Capricorn (23°26′14.0″S). While we often think of the tropics as consistently warm and wet throughout the year, in reality, the tropics maintain a myriad of...

The uplift history of the Colorado Plateau has been debated for over a century with still no unified hypotheses for the cause, timing, and rate of uplift. 40Ar/39Ar and K/Ar dating of recurrent basaltic volcanism over the past ∼6 Ma within the Virgin River drainage system, southwest Utah, northwest Arizona, and...
Drought forecasting for streams and groundwaters in northeastern United States
Samuel H. Austin, Robert W. Dudley
2019, Fact Sheet 2019-3015
BackgroundWhen rainfall is lower than normal over an extended period, streamflows decline, groundwater levels fall, and hydrological drought can occur. Droughts can reduce the water available for societal needs, such as public and private drinking-water supplies, farming, and industry, and for ecological health, such as maintenance of water quality and...

2019, Journal of Geophysical Research C: Oceans (124) 3490-3507
Offshore permafrost plays a role in the global climate system, but observations of permafrost thickness, state, and composition are limited to specific regions. The current global permafrost map shows potential offshore permafrost distribution based on bathymetry and global sea level rise. As a first‐order estimate, we employ a heat transfer...
