2017, Scientific Reports (7)
The distribution of rainfed agriculture is expected to respond to climate change and human population growth. However, conditions that support rainfed agriculture are driven by interactions among climate, including climate extremes, and soil moisture availability that have not been well defined. In the temperate regions that support much...

2017, Scientific Reports (7)
Arctic Ocean temperatures influence ecosystems, sea ice, species diversity, biogeochemical cycling, seafloor methane stability, deep-sea circulation, and CO2 cycling. Today's Arctic Ocean and surrounding regions are undergoing climatic changes often attributed to "Arctic amplification" - that is, amplified warming in Arctic regions due to sea-ice loss and other processes, relative to...

Anne J. Jefferson, Aditi S. Bhaskar, Kristina G. Hopkins, Rosemary M. Fanelli, Pedro M. Avellaneda, Sara K. McMillan
2017, Hydrological Processes (31) 4056-4080
Deleterious effects of urban stormwater are widely recognized. In several countries, regulations have been put into place to improve the conditions of receiving water bodies, but planning and engineering of stormwater control is typically carried out at smaller scales. Quantifying cumulative effectiveness of many stormwater control measures on a watershed...

Kyle E. Juracek
2017, Fact Sheet 2017-3083
The availability of adequate water to meet the present (2017) and future needs of humans, fish, and wildlife is a fundamental issue for the Prairie Band Potawatomi Nation in northeast Kansas. Because Soldier Creek flows through the Prairie Band Potawatomi Nation Reservation, it is an important tribal resource. An understanding...
Bathymetric map and area/capacity table for Castle Lake, Washington
Adam R. Mosbrucker, Kurt R. Spicer
2017, Open-File Report 2017-1145
The May 18, 1980, eruption of Mount St. Helens produced a 2.5-cubic-kilometer debris avalanche that dammed South Fork Castle Creek, causing Castle Lake to form behind a 20-meter-tall blockage. Risk of a catastrophic breach of the newly impounded lake led to outlet channel stabilization work, aggressive monitoring programs, mapping...
Novel RAD sequence data reveal a lack of genomic divergence between dietary ecotypes in a landlocked salmonid population
Morten T. Limborg, Wesley Larson, Kyle Shedd, Lisa W. Seeb, James E. Seeb
2017, Conservation Genetics Resources (10) 169-171
Preservation of heritable ecological diversity within species and populations is a key challenge for managing natural resources and wild populations. Salmonid fish are iconic and socio-economically important species for commercial, aquaculture, and recreational fisheries across the globe. Many salmonids are known to exhibit ecological divergence within species, including distinct feeding...
Grooming behaviors of black-tailed prairie dogs are influenced by flea parasitism, conspecifics, and proximity to refuge
David A. Eads, Dean E. Biggins, Samantha L. Eads
2017, Ethology (123) 924-932
Grooming is a common animal behavior that aids in ectoparasite defense. Ectoparasites can stimulate grooming, and natural selection can also favor endogenous mechanisms that evoke periodic bouts of “programmed” grooming to dislodge or kill ectoparasites before they bite or feed. Moreover, grooming can function as a displacement or communication behavior....

Building on that work, this paper describes an objectively derived and globally comprehensive set of 37 distinct volumetric region units, called ecological marine units (EMUs). They are constructed on...
No evidence of critical slowing down in two endangered Hawaiian honeycreepers
Jessica C. Rozek, Richard J. Camp, J. Michael Reed
2017, PLoS ONE (12) 1-18
There is debate about the current population trends and predicted short-term fates of the endangered forest birds, Hawai`i Creeper (Loxops mana) and Hawai`i `Ākepa (L. coccineus). Using long-term population size estimates, some studies report forest bird populations as stable or increasing, while other studies report signs of population decline or impending...

Patrick W. Moran, Lisa H. Nowell, Nile E. Kemble, Barbara Mahler, Ian R. Waite, Peter C. Van Metre
2017, Science of the Total Environment (599-600) 1469-1478
Simultaneous assessment of sediment chemistry, sediment toxicity, and macroinvertebrate communities can provide multiple lines of evidence when investigating relations between sediment contaminants and ecological degradation. These three measures were evaluated at 99 wadable stream sites across 11 states in the Midwestern United States during the summer of 2013 to assess...

Deniz Karagulle, Charlie Frye, Roger Sayre, Sean P. Breyer, Peter Aniello, Randy Vaughan, Dawn J. Wright
2017, Transactions in GIS (21) 1040-1060
In 1964, E.H. Hammond proposed criteria for classifying and mapping physiographic regions of the United States. Hammond produced a map entitled “Classes of Land Surface Form in the Forty-Eight States, USA”, which is regarded as a pioneering and rigorous treatment of regional physiography. Several researchers automated Hammond?s model in GIS....
Biological relevance of streamflow metrics: Regional and national perspectives
Daren Carlisle, Theodore E. Grantham, Ken Eng, David M. Wolock
2017, Freshwater Science (36) 927-940
Protecting the health of streams and rivers requires identifying ecologically significant attributes of the natural flow regime. Streamflow regimes are routinely quantified using a plethora of hydrologic metrics (HMs), most of which have unknown relevance to biological communities. At regional and national scales, we evaluated which of 509 commonly used...
