2021, Journal of Parasitology (107) 600-605
Under Wisconsin state law, the greater prairie chicken (GRPC; Tympanuchus cupido pinnatus) has been listed as a threatened species since 1976. In 2014–15, we conducted a pilot study to determine the prevalence and intensity of gapeworms (Syngamus spp.) in female Wisconsin GRPCs collected from 2 monitored populations. We captured 62 female GRPCs...

Paula Burgi, Juddith Hubbard, Syed Humayun Akhter, Dana E. Peterson
2021, Journal of Geophysical Research: Solid Earth (126)
Eastern Bangladesh sits on the seismically active Chittagong-Myanmar fold and thrust belt (CMFB), a north-trending accretionary wedge on the eastern side of the India-Eurasia collision. Earthquakes on the basal décollement and associated thrusts within the CMFB present a hazard to this densely populated region. In this study,...

Carlson, Charles Yackulic, James D. Nichols, James E. Hines, Raymond J. Davis, David W. Lamphear, Christopher McCafferty, Trent L. McDonald, Stan G. Sovern
2021, Proceedings of the National Academy of Sciences of the United States of America (PNAS) (118)
Invasive species can cause extinctions of native species and widespread biodiversity loss. Invader removal is a common management response, but the use of long-term field experiments to characterize effectiveness of removals in benefitting impacted native species is rare. We used a large-scale removal experiment to investigate the demographic...

Jacob Debow, Joshua Blouin, Elias Rosenblatt, Cedric Alexander, Katherina D. Gieder, Walter Cottrell, James Murdoch, Therese M. Donovan
2021, Journal of Wildlife Management (85) 1423-1439
Moose (Alces alces) have experienced considerable declines along the periphery of their range in the northeastern United States. In Vermont, the population declined 45% from 2010 to 2017 despite minimal hunter harvest and adequate habitat. Similarly, nearby populations recently experienced epizootics characterized by >50% mortality. Declines have largely been associated...

2021, Journal of Hydrology (602)
Post-fire hydrologic research typically focuses on the first few years after a wildfire, leading to substantial uncertainty regarding the longevity of impacts. The time needed for hydrologic function to return to pre-fire conditions is critical information for post-fire land...
Forest area to support landbird population goals for the Mississippi Alluvial Valley
Daniel J. Twedt, Anne Mini
2021, Open-File Report 2020-1097
Historically, the Mississippi Alluvial Valley (MAV) (Partners in Flight Bird Conservation Region #26) was predominantly bottomland hardwood forest, but natural vegetation has been cleared from about 80 percent of this ecoregion and converted primarily to agriculture. Because most bird species that are of conservation concern in this region are dependent...

2021, Environment International (152)
Florida manatees depend on freshwater environments as a source of drinking water and as warm-water refuges. These freshwater environments are in direct contact with human activities were glyphosate-based herbicides are being used. Glyphosate is the most used herbicide worldwide and it is intensively used in Florida as a sugarcane ripener...

2021, Limnology and Oceanography (66) 3568-3581
Estuaries exist across a large climatic gradient in the northwestern Gulf of Mexico, capturing a range of hydrologic conditions and estuarine functioning. We examined freshwater inflow, salinity, and stable isotope compositions (δ13C, δ15N) of oysters, suspended particulate organic matter (SPOM), and surface sediment organic matter (SSOM) from five estuaries across...

We found that each design was effective...
New amphibian and reptile parish records from Louisiana, USA
Brad Glorioso
2021, Herpetological Review (52) 364-366
Dundee and Rossman (1989) published distribution maps of Louisiana herpetofaunal species in The Amphibians and Reptiles of Louisiana over 30 years ago. Since then many records have been published, mostly in Herpetological Review, documenting additions to these original maps. Though many are single species additions, several compilations of new Louisiana...

2021, Ornithological Applications (123)
As an obligate salt marsh species, Seaside Sparrows (Ammospiza maritima) are vulnerable to numerous threats including climate change, coastal erosion, sea-level rise, and both natural and anthropogenic disasters. Of the 9 recognized subspecies, 2 are extinct and 1 is endangered. Previous genetic analyses of mitochondrial DNA (mtDNA) and microsatellite loci...

Kim T. Fredricks, Nicholas S. Johnson, Terrance Hubert, Mike Siefkes
2021, Journal of Great Lakes Research (47) S448-S454
Since the identification of 3-trifluoromethyl-4-nitrophenol as a lampricide in the 1950s, control of sea lamprey populations in the Great Lakes has largely relied on lampricides, barriers, and traps. Lampricide treatments target larval lampreys in tributaries of the Great Lakes. The Great...
