User’s manual to update the National Wildlife Refuge System Water Quality Information System (WQIS)
Kimberly A. Chojnacki, Chad J. Vishy, Jo Ellen Hinck, Susan E. Finger, Michael J. Higgins, Kevin Kilbride
2013, Techniques and Methods 11-C8
National Wildlife Refuges may have impaired water quality resulting from historic and current land uses, upstream sources, and aerial pollutant deposition. National Wildlife Refuge staff have limited time available to identify and evaluate potential water quality issues. As a result, water quality–related issues may not be resolved until a problem...

2013, Global Change Biology (19) 911-922
Although climate change is predicted to place mountain-top and other narrowly endemic species at severe risk of extinction, the ecological processes involved in such extinctions are still poorly resolved. In addition, much of this biodiversity loss will likely go unobserved, and therefore largely unappreciated. The Haleakalā silversword is restricted to...

Building from existing probabilistic methods for assessing the volumes of energy and mineral resources, we provide an algorithm for consistent,...
Relating hyporheic fluxes, residence times, and redox-sensitive biogeochemical processes upstream of beaver dams
Martin A. Briggs, Laura Lautz, Danielle K. Hare
2013, Freshwater Science (32) 622-641
Abstract. Small dams enhance the development of patchy microenvironments along stream corridors by trapping sediment and creating complex streambed morphologies. This patchiness drives intricate hyporheic flux patterns that govern the exchange of O2 and redox-sensitive solutes between the water column and the stream bed. We used multiple tracer techniques, naturally...

The ChemCam instrument, which provides insight into martian soil chemistry at the submillimeter scale, identified two principal soil types along the Curiosity rover traverse: a fine-grained mafic type and a locally derived, coarse-grained felsic type. The mafic soil component is representative of widespread martian soils and is similar in composition...

2013, Book chapter, Reptiles in research: investigations of ecology, physiology, and behavior from desert to sea
Locations of important foraging areas are not well defined for many marine species. Unraveling these mysteries is vital to develop conservation strategies for these species, many of which are threatened or endangered. Satellite-tracking is a tool that can reveal movement patterns at both broad and fine spatial scales, in all...
Predicting thermal reference conditions for USA streams and rivers
Ryan A. Hill, Charles P. Hawkins, Daren M. Carlisle
2013, Freshwater Science (32) 39-55
Temperature is a primary driver of the structure and function of stream ecosystems. However, the lack of stream temperature (ST) data for the vast majority of streams and rivers severely compromises our ability to describe patterns of thermal variation among streams, test hypotheses regarding the effects of temperature on macroecological...
Avoiding The Inevitable? Capacity Loss From Reservoir Sedimentation
John R. Gray, Timothy J. Randle, Kent L. Collins
2013, Eos, Transactions, American Geophysical Union (94) 4-4
The inexorable loss of capacity of the nation's reservoirs—sooner or later threatening water supplies for municipal, agricultural, and industrial uses—is but one of a number of deleterious effects wrought by sediment deposition. Trapped sediments can also damage or bury dam outlets, water intakes, and related infrastructure. Downstream effects of sediment...

Epizootic mortality in several geese species, including cackling geese (Branta hutchinsii) and Canada geese (Branta canadensis), has been recognized in the Willamette Valley of Oregon for over a decade. Birds are generally found dead on a body of water or are occasionally observed displaying neurologic clinical signs such as an...
The coming megafloods
Michael D. Dettinger, B. Lynn Ingram
2013, Scientific American (308) 64-71
Geologic evidence shows that truly massive floods, caused by rainfall alone, have occurred in California about every 200 years. The most recent was in 1861, and it bankrupted the state. Such floods were most likely caused by atmospheric rivers: narrow bands of water vapor about a mile above the ocean...
