Environmental and biological factors influence migratory Sea Lamprey catchability: Implications for tracking abundance in the Laurentian Great Lakes
Sean A. Lewandoski, Gale A Bravener, Peter J. Hrodey, Scott M. Miehls
2019, Journal of Fish and Wildlife Management (11) 68-79
Sea Lamprey Petromyzon marinus population trends in the Great Lakes are tracked by trapping migratory adults in tributaries and using mark and recapture techniques to estimate abundance. Understanding what environmental and biological factors influence Sea Lamprey capture in tributaries is crucial to developing efficient trapping methods and reliable abundance...

2019, Fact Sheet 2019-3062
Using a geology-based assessment methodology, the U.S. Geological Survey estimated undiscovered, technically recoverable mean resources of 144 million barrels of shale oil and 559 billion cubic feet of shale gas in the Mississippian Delle Phosphatic Member of the Woodman Formation in the Eastern Great Basin Province of Nevada, Utah, and Idaho....
Assessment of the American woodcock singing-ground survey zone timing and coverage
J. D. Moore, Thomas R. Cooper, Rebecca D. Rau, David E. Andersen, J. P Duguay, C. Alan Stewart, David G. Krementz
2019, Conference Paper, Proceedings of the eleventh American woodcock symposium
The American woodcock (Scolopax minor; hereafter, woodcock) Singing-Ground Survey (SGS) was developed to inform management decisions by monitoring changes in the relative abundance of woodcock. The timing of the designated survey windows was designed to count resident woodcock while minimizing counting of migrating woodcock. Since the implementation of the SGS...
Estimating density and effective area surveyed for American woodcock
Stefanie M. Bergh, David E. Andersen
2019, Conference Paper, Proceedings of the eleventh American woodcock symposium
The American Woodcock (Scolopax minor; hereafter, woodcock) Singing-ground Survey (SGS) is conducted annually during the woodcock breeding season, and survey points along survey routes are set 0.4 mile (0.65 km) apart to avoid counting individual birds from >1 listening location. The effective area surveyed (EAS) at a listening point is...
Detection probability and occupancy of American woodcock during Singing-ground surveys
Stefanie M. Bergh, David E. Andersen
2019, Conference Paper, Proceedings of the eleventh American woodcock symposium
The Singing-ground Survey (SGS) was designed to exploit the conspicuous breeding-season display of male American woodcock (Scolopax minor; hereafter, woodcock) to monitor these otherwise inconspicuous birds. The SGS was standardized in 1968 and has since been conducted annually to derive an index of abundance and population trend. Counts of singing...
Comparing live-capture methods for nutria: single- versus multiple-capture cage traps
Trevor R. Sheffels, Jacoby Carter, Mark S. Sytsma, Jimmy D. Taylor
2019, Human-Wildlife Interactions (13) 394-399
Herbivory and burrowing by nutria (Myocastor coypus) cause substantial ecological and economic damage. Trapping is a common, effective practice for reducing nutria damage; however, trapping approaches must continually be adapted to keep pace with evolving animal welfare and ethical issues and to more effectively target pest species of interest. Our objective was to evaluate...
Observations of the spawning ecology of the imperiled Clear Lake Hitch Lavinia exilicauda chi
Frederick V. Feyrer
2019, California Fish and Game (105) 225-232
Migrations for the purposes of reproduction are widely documented across the animal kingdom and are particularly common in fishes and other aquatic organisms (Dingle 2014). One important migration strategy in fishes is potamodromy, which is the movement from one location to another entirely within freshwater (Morais and Daverat 2016)....
Reach-scale monitoring and modeling of rivers--Expanding hydraulic data collection beyond the cross section
Brandon T. Forbes, Claire E. Bunch, Geoffrey DeBenedetto, Corey J. Shaw, Bruce Gungle
2019, Fact Sheet 2019-3073
For over 125 years, the U.S. Geological Survey streamgage network has provided important hydrologic information about rivers and streams throughout the Nation. Traditional streamgage methods provide reliable stage and streamflow data but typically only monitor stage at a single location in a river and require frequent calibration streamflow measurements. Direct measurements are...

Yusuke Sawa, Chieko Tamura, Toshio Ikeuchi, Kaoru Fujii, Aisa Ishioroshi, T. Shimada, David H. Ward
2019, Wildfowl (69) 230-241
Effective and efficient capture methods are needed for marking and monitoring individuals in studies of demography, migration and habitat use. We describe a novel use of leg-hold nooses aligned on lines and mats to capture non-breeding Brent Geese Branta bernicla in water at a staging and wintering site in Japan....

We correct a sign error in Figs. 1 and 2. We also correct the equation for the prime meridian position (W) of...
Estimating the degree to which distance and temperature differences drive changes in fish community composition over time in the upper Mississippi River
James H. Larson, Jonathan M. Vallazza, Brent C. Knights
2019, PLoS ONE (14)
Similarity in community composition declines as distance between locations increases, a phenomenon that has been observed in a wide variety of freshwater, marine and terrestrial ecosystems. One driver of the distance-similarity relationship is the presence of environmental gradients that alter the suitability of sites for particular species. Although...

Survival rates and stopover persistence of American Woodcock using Cape May, New Jersey during fall migration
Daniel McAuley, Guthrie S. Zimmerman, B. L. Allen, C. Dwyer, T.R. Cooper
2019, Conference Paper, Proceedings of the eleventh American Woodcock symposium
Cape May, New Jersey is an important stopover area for American woodcock (Scolopax minor, hereafter woodcock) during fall migration along the Atlantic Coast of the United States. Previous research has indicated that many woodcock stop at Cape May prior to crossing Delaware Bay; however, little is known about survival of...

2019, Nature Plants (5) 1222-1228
Mast seeding is one of the most intriguing reproductive traits in nature. Despite its potential drawbacks in terms of fitness, the widespread existence of this phenomenon suggests that it should have evolutionary advantages under certain circumstances. Using a global dataset of seed production time series for 219 plant species from...

Using pointing dogs and hierarchical models to evaluate American woodcock winter occupancy and densities
Daniel S. Sullins, Warren C. Conway, David A. Haukos, Christopher E. Comer
2019, Conference Paper, Proceedings of the eleventh American Woodcock Symposium
Use of dogs has increased for multiple wildlife research purposes ranging from carnivore scat detection to estimation of reptile abundance. Use of dogs is not particularly novel for upland gamebird biologists, and pointing dogs have been long considered an important research tool. However, recent advances in Global Positioning System (GPS)...

2019, Marine and Coastal Fisheries: Dynamics, Management, and Ecosystem Science (11) 437-453
Information on the movement patterns of fishes is essential for managers that are making critical resource decisions. We examined the frequency of a keystone species, Chinook Salmon Oncorhynchus tshawytscha that migrated from different marine basins to the Nisqually River estuary, which lies within the southernmost marine basin (hereafter, “South basin”)...

2019, Economic Geology (114) 1569-1598
The iron oxide-apatite (IOA) deposits of the eastern Adirondack Highlands, New York, are historical high-grade magnetite mines that contain variable concentrations of rare earth element (REE)-bearing apatite crystals. The majority of the deposits are hosted within sodically altered Lyon Mountain granite gneiss, although some deposits occur within paragneiss,...

2019, Management of Biological Invasions (10) 602-616
Colonization of eelgrass (Zostera marina L.) by tunicates can lead to reduced plant growth and survival. Several of the tunicate species that are found on eelgrass in the northwest Atlantic are highly aggressive colonizers, and range expansions are predicted in association with climate-change induced increases in seawater temperature. In 2017, we...
