Evidence of sound production by spawning lake trout (Salvelinus namaycush) in lakes Huron and Champlain
Nicholas S. Johnson, Dennis Higgs, Thomas R. Binder, J. Ellen Marsden, Tyler John Buchinger, Linnea Brege, Tyler Bruning, Steve A. Farha, Charles C. Krueger
2018, Canadian Journal of Fisheries and Aquatic Sciences (75) 429-438
Two sounds associated with spawning lake trout (Salvelinus namaycush) in lakes Huron and Champlain were characterized by comparing sound recordings to behavioral data collected using acoustic telemetry and video. These sounds were named growls and snaps, and were heard on lake trout spawning reefs, but not on a non-spawning reef,...
Crater density differences: Exploring regional resurfacing, secondary crater populations, and crater saturation equilibrium on the moon
R. Z. Povilaitis, M. S. Robinson, C. H. van der Bogert, Harald Hiesinger, H. M. Meyer, Lillian R. Ostrach
2018, Planetary and Space Science (162) 41-51
The global population of lunar craters >20 km in diameter was analyzed by Head et al., (2010) to correlate crater distribution with resurfacing events and multiple impactor populations. The work presented here extends the global crater distribution analysis to smaller craters (5–20 km diameters, n = 22,746). Smaller craters form at a higher rate than...

Microhabitat and biology of Sphaerium striatinum in a central New York stream
Dawn E. Dittman, James H. Johnson, Christopher C. Nack
2018, Hydrobiologia (810) 367-374
In many lotic systems, drastic declines in freshwater bivalve populations, including fingernail clams (Sphaeriidae), have created concerns about biodiversity and future ecosystem services. We examined the local occurrence of the historically common fingernail clam, Sphaerium striatinum, in a central New York stream. We sampled the density of sphaeriids...

The NMIC...
Spawning site fidelity and apparent annual survival of walleye (Sander vitreus) differ between a Lake Huron and Lake Erie tributary
Todd A. Hayden, Thomas Binder, Christopher M. Holbrook, Christopher Vandergoot, David G. Fielder, Steven J. Cooke, John M. Dettmers, Charles C. Krueger
2018, Ecology of Freshwater Fish (27) 339-349
Fidelity to spawning habitats can maximise reproductive success of fish by synchronising movements to sites of previous recruitment. To determine the role of reproductive fidelity in structuring walleye Sander vitreus populations in the Laurentian Great Lakes, we used acoustic telemetry combined with Cormack–Jolly–Seber capture–recapture models to estimate spawning site fidelity...

2018, Plant and Soil (422) 183-194
Background and aimsWe characterized fungal endophytes of seeds of invasive, non-native Phragmites from three sites in the Great Lakes region to determine if fungal symbiosis could contribute to invasiveness through their effects on seed germination and seedling growth.MethodsField-collected...

Erin S. Dunlop, Robert L. McLaughlin, Jean V. Adams, Michael L. Jones, Oana Birceanu, Mark R. Christie, Lori A. Criger, Julia Hinderer, Robert M. Hollingworth, Nicholas S. Johnson, Stephen R. Lantz, Weiming Li, James R. Miller, Bruce J. Morrison, David Mota-Sanchez, Andrew M. Muir, Maria S. Sepulveda, Todd B. Steeves, Lisa Walter, Erin Westman, Isaac Wirgin, Michael P. Wilkie
2018, Canadian Journal of Fisheries and Aquatic Sciences (75) 152-168
Rapid evolution of pest, pathogen and wildlife populations can have undesirable effects; for example, when insects evolve resistance to pesticides or fishes evolve smaller body size in response to harvest. A destructive invasive species in the Laurentian Great Lakes, the sea lamprey (Petromyzon marinus) has been controlled with the pesticide...
Interoperability in planetary research for geospatial data analysis

2018, Planetary and Space Science (150) 36-42
For more than a decade there has been a push in the planetary science community to support interoperable methods for accessing and working with geospatial data. Common geospatial data products for planetary research include image mosaics, digital elevation or terrain models, geologic maps,...
Diet of the Antillean manatee (Trichechus manatus manatus) in Belize, Central America
Aarin Conrad Allen, Cathy A. Beck, Robert K. Bonde, James A. Powell, Nicole Auil Gomez
2018, Journal of the Marine Biological Association of the United Kingdom (98) 1831-1840
Belize contains important habitat for Antillean manatees (Trichechus manatus manatus) and provides refuge for the highest known population density of this subspecies. As these animals face impending threats, knowledge of their dietary habits can be used to interpret resource utilization. The contents of 13 mouth, 6 digestive tract (stomach, duodenum...
Shallow bedrock limits groundwater seepage-based headwater climate refugia
Martin A. Briggs, John W. Lane Jr., Craig D. Snyder, Eric A. White, Zachary Johnson, David L. Nelms, Nathaniel P. Hitt
2018, Limnologica - Ecology and Management of Inland Waters (68) 142-156
Groundwater/surface-water exchanges in streams are inexorably linked to adjacent aquifer dynamics. As surface-water temperatures continue to increase with climate warming, refugia created by groundwater connectivity is expected to enable cold water fish species to survive. The shallow alluvial aquifers that source groundwater seepage to headwater streams, however, may also be...

John A. Barron, David Bukry, Linda E. Heusser, Jason A. Addison, Clark R. Alexander Jr.
2018, Quaternary International (469) 109-119
Piston core TN062-O550, collected about 33 km offshore of Eureka, California, contains a high-resolution record of the climate and oceanography of coastal northernmost California during the past ∼7.34 kyr. Chronology established by nine AMS ages on a combination of planktic foraminifers, bivalve shell fragments, and wood yields a mean sedimentation rate of...
Slip history of the La Cruz fault: Development of a late Miocene transformin response to increased rift obliquity in the northern Gulf of California
Scott E.K. Bennett, Michael E. Oskin, Alexander Iriondo, Michael J. Kunk
2018, Tectonophysics (693) 409-435
The Gulf of California rift has accommodated oblique divergence of the Pacific and North America plates in north-western México since Miocene time. Due to its infancy, its rifted margins preserve a rare onshore record of early continental break-up processes and an opportunity to investigate the role of rift obliquity in...
Bioenergetic evaluation of diel vertical migration by bull trout (Salvelinus confluentus) in a thermally stratified reservoir
Madeleine Eckmann, Jason B. Dunham, Edward J. Connor, Carmen A. Welch
2018, Ecology of Freshwater Fish (27) 30-43
Many species living in deeper lentic ecosystems exhibit daily movements that cycle through the water column, generally referred to as diel vertical migration (DVM). In this study, we applied bioenergetics modelling to evaluate growth as a hypothesis to explain DVM by bull trout (Salvelinus confluentus) in a thermally stratified reservoir...

Climate-induced seasonal changes in smallmouth bass growth rate potential at the southern range extent
Christopher R. Middaugh, Brin Kessinger, Daniel D. Magoulick
2018, Ecology of Freshwater Fish (27) 19-29
Temperature increases due to climate change over the coming century will likely affect smallmouth bass (Micropterus dolomieu) growth in lotic systems at the southern extent of their native range. However, the thermal response of a stream to warming climate conditions could be affected by the flow regime of...

Michael R. Rosen, Arica Crootof, Liam Reidy, Laurel Saito, Bakhriddin Nishonov, Julian A. Scott
2018, Journal of Paleolimnology (59) 201-219
The economy of the Khorezm Province in Uzbekistan relies on the large-scale agricultural production of cotton. To sustain their staple crop, water from the Amu Darya is diverted for irrigation through canal systems constructed during the early to mid-twentieth century when this region was part of the Soviet Union. These...
