Enhancing ecosystem restoration efficiency through spatial and temporal coordination. PNAS 112 (19) 6236-6241; published ahead of print April 27, 2015
We use a return-on-investment framework to assess the value of coordinating restoration efforts in space and time to maximize ecological connectivity between the Laurentian Great Lakes and their tributaries, which are fragmented by hundreds of thousands of dams and road crossings.
Childress, E.S., Papke, R., and P.B. McIntyre (2015) Spawning success and early life history of longnose suckers in Great Lakes tributaries. Freshwater Biology DOI: 10.1111/eff.12220
Fish eggs and larvae are often subject to very high mortality, and variation in early life survival can be important for population dynamics. Although longnose suckers (Catostomus catostomus) are widespread in northern North America, little is known about their early life history.
Childress, E.S., and McIntyre, P.B. (2014) Multiple nutrient subsidy pathways from a spawning migration of iteroparous fish. Freshwater Biology 60: 490-499. DOI: 10.1111/fwb.12494
Our objective was to determine the importance of excretion, eggs and carcasses as nutrient sources from a large migration of longnose suckers into a stream draining a moderately agricultural catchment. Additionally, we evaluated nutrient limitation in the stream using nutrient-diffusing substrates and determined the timing of nutrient releases during egg decomposition using a microcosm experiment.

Our objectives are to (1) summarize the science of hard-part microchemistry; (2) provide guidelines for designing hard-part microchemistry studies, including sample sizes, laboratory analyses, statistical techniques, and inferential limitations; and (3) identify conservation and management applications where these techniques may be particularly useful.

Our goal was to predict road culvert passability, as defined by culvert outlet drop and outlet water velocity, for three fish swimming groups using remotely collected environmental variables that have been shown to influence the passability of road culverts.
Hamann E. J., Kennedy B. P., Whited D. C., and Stanford J. A. (2014) Spatial variability in spawning habitat selection by Chinook salmon (Oncorhynchus tshawytshca) in a wilderness river. River Research and Applications 30: 1099–1109. DOI: 10.1002/rra.2704
To examine how physical habitat variables influenced spawning habitat choice in one central Idaho (USA) wilderness stream, we used remote sensing techniques to classify and quantify the total amount of each aquatic habitat type present to assess how habitat quantity changed as stream order increased. Additionally, we measured physical habitat variables at each redd throughout the entire stream length for one spawning season to assess whether Chinook salmon selected for the same habitat parameters at varying spatial scales.
Hogan, J.D., McIntyre, P., Blum, M., Gilliam, J., and Bickford, N. (2014) Consequences of alternative dispersal strategies in a putatively amphidromous fish. Ecology 95: 2397.
Here we investigate variability in dispersal histories of a freshwater fish, Awaous stamineus, across the species' entire geographic range in the Hawaiian archipelago.
Pracheil, B., Mestl, G., and Pegg, M. (2014) Movement through dams facilitates population connectivity in a large river. River Research and Applications DOI: 10.1002/rra.2751
We used 1995–2008 paddlefish mark–recapture data to perform the following: (i) quantify rates of movement through dams and (ii) examine the influence of dam discharge on fish passing dams.
Childress, E., Allan, J., and McIntyre, P. (2014) Nutrient subsidies from iteroparous fish migrations can enhance stream productivity. Ecosystems 17: 522-534.
To test whether iteroparous species can provide ecologically important nutrient inputs to stream ecosystems, we experimentally blocked the migration of suckers (Catostomidae) midway up an oligotrophic tributary of Lake Michigan.

We propose that certain tributaries, by virtue of their lower degree of alteration, offer underappreciated opportunities for conserving large-river biota.

To prioritize actions aimed at restoring connectivity, we argue that there is a need for systematic inventories of these potential barriers at regional and national scales. Here, we address this limitation for the North American Great Lakes basin by compiling the best available spatial data on the locations of dams and road crossings.

Our goal was to evaluate the potential consequences of future land use on freshwater ecosystems in the coterminous United States by comparing alternative scenarios of land use change (2001–2051) with current patterns of freshwater biodiversity and water quality risk.

Herein, we quantify straying away from natal origins by adult chinook salmon (Oncorhynchus tshawytscha) in a wild population that inhabits a pristine wilderness basin. Using natural isotopic signatures (87Sr/86Sr) to reconstruct the migratory behaviors of unhandled individuals over their entire life cycle, we identified ecological and behavioral factors influencing the propensity to stray.
Pracheil, B., Powell, L., Pegg, M., and Mestl, G. (2012) Swimways: protecting paddlefish through movement-centered management. Fisheries 37: 449-457.
We used 1988–2009 data from the MICRA paddlefish (Polyodon spathula) stock assessment database—a database containing mark-recapture and biometric information on more than 30,000 individually marked wild paddlefish and more than 2 million hatchery origin paddlefish—to estimate survival and movement across large and potentially biologically relevant spatial scales.

This study examines nearly 40 years of young-of-year (yoy) paddlefish recruitment data to investigate the hypothesis that tributaries influence mainstem fish population dynamics.
