Quantifying microplastics in Indiana’s Lake Michigan watershed and submerged aquatic vegetation
Julie R. Peller, Meredith B. Nevers, Muruleedhara Byappanahalli, Mary Anne Evans
2020, Newsletter
Environmental breakdown of plastics produces synthetic microfibers, a class of microplastics that are most prevalent in surface waters. A main source of these pollutants is wastewater treatment plants which discharge into surface waters, including those that flow into Lake Michigan. Microplastics can settle into aquatic sediment or exist for lengths...

Testing hypotheses on signatures of precipitation variability in the river and floodplain deposits of the Paleogene San Juan Basin, New Mexico, USA
Kristine L. Zellman, Piret Plink-Bjorklund, Henry Fricke
2020, Journal of Sedimentary Research (90) 1770-1801
Much progress has been made in recent years towards a set of recognition criteria for river discharge variability in river channel deposits, and thus sedimentary proxies for precipitation variability. Despite this progress, there is currently no consensus on how different styles of discharge variability are reflected in river sedimentary records,...

Pamela J. Lombard, Janet R. Barclay, Dee-Ann E. Crozier
2020, Open-File Report 2020-1148
Below average and infrequent rainfall from May through September 2020 led to an extreme hydrologic drought across much of New England, with some areas experiencing a flash drought, reflecting its quick onset. The U.S. Geological Survey (USGS) recorded record-low streamflow and groundwater levels throughout the region. In September, the U.S....
Mapping Phragmites australis live fractional cover in the lower Mississippi River Delta, Louisiana
Amina Rangoonwala, Rebecca J. Howard, Elijah W. Ramsey III
2020, Open-File Report 2020-1131
In response to a co-occurring non-native scale infestation and Phragmites australis dieback in southeast Louisiana, normalized difference vegetation index (NDVI) satellite mapping was implemented to track P. australis condition in the lower Mississippi River Delta. While the NDVI mapping successfully documented relative condition changes, identification of cause required a quantitative-biophysical...
Reptiles under the conservation umbrella of the greater sage‐grouse
David S. Pilliod, Michelle I. Jeffries, Robert Arkle, Deanna H. Olson
2020, Journal of Wildlife Management (84) 478-491
In conservation paradigms, management actions for umbrella species also benefit co‐occurring species because of overlapping ranges and similar habitat associations. The greater sage‐grouse (Centrocercus urophasianus) is an umbrella species because it occurs across vast sagebrush ecosystems of western North America and is the recipient of extensive...
Management of the brown-headed cowbird: Implications for endangered species and agricultural damage mitigation
Brian D Peer, Barbara E. Kus, Mary J. Whitfield, Linnea S. Hall, Stephen I Rothstein
2020, Human-Wildlife Interactions (14)
The brown-headed cowbird (Molothrus ater; cowbird) is unique among North American blackbirds (Icteridae) because it is managed to mitigate the negative effects on endangered songbirds and economic losses in agricultural crops. Cowbird brood parasitism can further affect species that are considered threatened or endangered due to anthropogenic land...

Underwater photographic reconnaissance and habitat data collection in the Florida Keys—A procedure for ground truthing remotely sensed bathymetric data
Zachery W. Fehr, Kimberly K. Yates
2020, Open-File Report 2020-1118
Bathymetric geoprocessing analyses of the Florida Reef Tract have provided insights into trends of seafloor accretion and seafloor erosion over time and following major storm events. However, bathymetric surveys sometimes capture manmade structures and vegetation, which do not represent the desired bare-earth data. Therefore, ground truthing is essential to maintain...

In 2019, total daily tight oil and gas production increased in the United States month over month, with annualized growth of 14% for oil and 12% for gas. Those gains leveled off in the first quarter of 2020 due to aggressive price competition and increases in international production. Then came...
Using biodiversity metrics to guide conservation planning in altered tropical landscapes
K. E. Battle, Krishna Pacifici, Jaime A. Collazo, B. J. Reigh
2020, Caribbean Naturalist (77)
Biodiversity metrics are frequently used to guide conservation planning because they can summarize biogeographical attributes of plant and animal communities quickly and at multiple scales. Attributes include habitat features of high conservation value, representativeness, and redundancy of biological communities. We conducted a rapid ecological assessment of resident avian species in...

Identifying and assessing priority transboundary aquifers along the United States- Mexico border
Nathaniel Kyle Pasley
2020, Report
Many of the 15 million inhabitants along the United States-Mexico border derive fresh water from transboundary aquifers straddling and extending far beyond the political boundary separating the two countries. The previous lack of a large-scale cooperative and structured data collection effort and groundwater management strategy for the region has left...
