Muskie lunacy: does the lunar cycle influence angler catch of muskellunge (Esox masquinongy)?
Mark R. Vinson, Ted R. Angradi
2014, PLoS ONE (9)
We analyzed angling catch records for 341,959 muskellunge (Esox masquinongy) from North America to test for a cyclic lunar influence on the catch. Using periodic regression, we showed that the number caught was strongly related to the 29-day lunar cycle, and the effect was consistent across most fisheries. More muskellunge...

Rainbow Smelt Osmerus mordax are native to northeastern Atlantic and Pacific–Arctic drainages and have been widely introduced throughout North America. In the Great Lakes region, Rainbow Smelt are known predators and competitors of native fish and a primary prey species in pelagic food webs. Despite their widespread distribution, importance as...
Remote sensing of land surface phenology
G.A. Meier, Jesslyn F. Brown
2014, Fact Sheet 2014-3052
Remote sensing of land-surface phenology is an important method for studying the patterns of plant and animal growth cycles. Phenological events are sensitive to climate variation; therefore phenology data provide important baseline information documenting trends in ecology and detecting the impacts of climate change on multiple scales. The USGS Remote...

2014, Open-File Report 2014-1020
Slug tests were conducted on 56 observation wells open to bedrock at the former Naval Air Warfare Center (NAWC) in West Trenton, New Jersey. Aquifer transmissivity (T) and storage coefficient (S) values for most wells were estimated from slug-test data using the Cooper-Bredehoeft-Papadopulos method. Test data from three wells exhibited...
Spatial variability and landscape controls of near-surface permafrost within the Alaskan Yukon River Basin
Neal J. Pastick, M. Torre Jorgenson, Bruce K. Wylie, Joshua R. Rose, Matthew Rigge, Michelle Ann Walvoord
2014, Journal of Geophysical Research: Biogeosciences (119) 1244-1265
The distribution of permafrost is important to understand because of permafrost's influence on high-latitude ecosystem structure and functions. Moreover, near-surface (defined here as within 1 m of the Earth's surface) permafrost is particularly susceptible to a warming climate and is generally poorly mapped at regional scales. Subsequently, our objectives were to...

2014, Conservation Genetics Resources (6) 349-351
Blackfishes (Esociformes: Esocidae: Dallia), small fishes with relictual distributions, are unique in being the only primary freshwater fish genus endemic to Beringia. Although the number of species of Dallia is debated, disjunct populations and distinct mitochondrial divisions that predate the end of the last glacial maximum are apparent. We developed...
Traditional cultural use as a tool for inferring biogeography and provenance: a case study involving painted turtles (Chrysemys picta) and Hopi Native American culture in Arizona, USA
Jeffrey E. Lovich, Charles T. LaRue, Charles A. Drost, Terence R. Arundel
2014, Copeia (2014) 215-220
Inferring the natural distribution and native status of organisms is complicated by the role of ancient and modern humans in utilization and translocation. Archaeological data and traditional cultural use provide tools for resolving these issues. Although the painted turtle (Chrysemys picta) has a transcontinental range in the United States, populations...

Barnett A. Rattner, Rebecca S. Lazarus, John E. Elliott, Richard F. Shore, Nico van den Brink
2014, Environmental Science & Technology (48) 8433-8445
Despite a long history of successful use, routine application of some anticoagulant rodenticides (ARs) may be at a crossroad due to new regulatory guidelines intended to mitigate risk. An adverse outcome pathway for ARs was developed to identify information gaps and end points to assess the effectiveness of regulations. This...
