2018, Data Series 1094
Because coastal areas in Connecticut, Rhode Island, and Massachusetts were heavily affected by Hurricane Sandy in October 2012, the U.S. Geological Survey (USGS), under a mission agreement with the Federal Emergency Management Agency, collected storm tide high-water marks in those coastal areas. This effort was undertaken to better understand the...

Enrico Pirotta, Todd E. Katzner, Tricia A. Miller, Adam E. Duerr, Melissa A. Braham, Leslie New
2018, Functional Ecology (32) 2205-2215
Characterising the spatiotemporal variation of animal behaviour can elucidate the way individuals interact with their environment and allocate energy. Increasing sophistication of tracking technologies paired with novel analytical approaches allows the characterisation of movement dynamics even when an individual is not directly observable.In this study, high‐resolution movement data collected...

The Brook Floater (Alasmidonta varicosa) is a small (<100 mm), stream dwelling freshwater mussel (Family: Unionidae) from Atlantic Slope drainages in the eastern U.S. (Nedeau 2008). Brook Floater have dramatically contracted in distribution over recent decades, and there is limited evidence of recruitment in most locations, despite minimal effort to...
Sediment transport and deposition
Joel B. Sankey, Amy E. East, Jason R. Kreitler, Christina (Naomi) Tague
2018, Book chapter, Central Coast Summary Report. California’s Fourth Climate Change Assessment
Sediment transport and deposition (sedimentation) occurs from natural and anthropogenic sources in rivers, lakes, and reservoirs. Substantial changes in sediment transport (such as a major increase or decrease in sediment supply) can impact aquatic ecosystems that depend on a particular sediment quantity and particle size, for example, through altering stream-channel...
The risk of rodent introductions from shipwrecks to seabirds on Aleutian and Bering Sea islands
Martin Renner, Eric Nelson, Jordan Watson, Alan Haynie, Aaron Poe, Martin D. Robards, Steve C. Hess
2018, Biological Invasions (20) 2679-2690
Accidental introductions of rodents present one of the greatest threats to indigenous island biota, especially seabirds. On uninhabited remote islands, such introductions are likely to come from shipwrecks. Here we use a comprehensive database of shipwrecks in Western Alaska to model the frequency of shipwrecks per Aleutian and Bering Sea...

Divisions of geologic time—Major chronostratigraphic and geochronologic units
U.S. Geological Survey Geologic Names Committee
2018, Fact Sheet 2018-3054
IntroductionEffective communication in the geosciences requires a consistent nomenclature for stratigraphic units and, especially, for divisions of geologic time.

2018, Canadian Journal of Zoology (96) 1353-1365
Understanding full annual cycle movements of long-distance migrants is essential for delineating populations, assessing connectivity, evaluating crossover effects between life stages, and informing management strategies for vulnerable or declining species. We used implanted satellite transmitters to track up to 2 years of annual cycle movements of 52 adult female White-winged...

Jeb A. Barzen, Sarah J. Converse, Peter H. Adler, Anne E Lacy, Elmer Gray, Andrew Gossens
2018, Condor (120) 632-649
Understanding multiple challenges that restrict conservation success is a central task of applied ecology, especially when resources are limited and actions are expensive, such as with reintroduction programs. Simultaneous consideration of multiple hypotheses can expedite identification of factors that most limit conservation success. Since 2001, reintroduction of a migratory population...
