Mark S. Martell, Richard O. Bierregaard Jr., Brian E. Washburn, John E. Elliott, Charles J. Henny, Robert S. Kennedy, Iain MacLeod
2014, Journal of Raptor Research (48) 309-324
Most North American Ospreys (Pandion haliaetus) are migratory, breeding in northern latitudes and migrating long distances to and from their wintering grounds in the tropics. Although fall migration patterns of North American Ospreys have been described and studied, very little has been published about the spring migration of these birds....
Estimates of natural salinity and hydrology in a subtropical estuarine ecosystem: implications for Greater Everglades restoration
Frank E. Marshall, G. Lynn Wingard, Patrick A. Pitts
2014, Estuaries and Coasts (37) 1449-1466
Disruption of the natural patterns of freshwater flow into estuarine ecosystems occurred in many locations around the world beginning in the twentieth century. To effectively restore these systems, establishing a pre-alteration perspective allows managers to develop science-based restoration targets for salinity and hydrology. This paper describes a process to develop...
Evaluating the long-term management of introduced ungulates to protect the palila, an endangered bird, and its criticial habitat in subalpine forest of Mauna Kea, Hawai'i

2014, Arctic, Antarctic, and Alpine Research (46) 871-889
Under the multiple-use paradigm, conflicts may arise when protection of an endangered species must compete with other management objectives. To resolve such a conflict in the Critical Habitat of the endangered Hawaiian honeycreeper, palila (Loxioides bailleui), federal courts ordered the eradication of introduced ungulates responsible for damaging the māmane (Sophora...

Christopher C. Funk, Andrew Hoell, Shraddhanand Shukla, Ileana Blade, Brant Liebmann, Jason B. Roberts, Franklin R. Robertson
2014, Hydrology and Earth System Sciences (11) 3111-3136
In southern Ethiopia, Eastern Kenya, and southern Somalia poor boreal spring rains in 1999, 2000, 2004, 2007, 2008, 2009 and 2011 contributed to severe food insecurity and high levels of malnutrition. Predicting rainfall deficits in this region on seasonal and decadal time frames can help decision makers support disaster risk...
Population viability of Pediocactus brady (Cactaceae) in a changing climate
Daniel F. Shryock, Todd C. Esque, Lee Huges
2014, American Journal of Botany (101) 1944-1953
• Premise of the study: A key question concerns the vulnerability of desert species adapted to harsh, variable climates to future climate change. Evaluating this requires coupling long-term demographic models with information on past and projected future climates. We investigated climatic drivers of population growth using a 22-yr demographic model for Pediocactus bradyi,...

2014, Marine Science (49) 146-154
The United Nations General Assembly in 2006 and 2009 adopted resolutions that call for the identification and protection of vulnerable marine ecosystems (VMEs) from significant adverse impacts of bottom fishing. While general criteria have been produced, there are no guidelines or protocols that elaborate on the process from initial identification through to...
A legacy of divergent fishery management regimes and the resilience of rainbow and cutthroat trout populations in Lake Crescent, Olympic National Park, Washington
Samuel J. Brenkman, Jeffrey J. Duda, Philip R. Kennedy, Bruce M. Baker
2014, Northwest Science (88) 280-304
As a means to increase visitation, early fisheries management in the National Park Service (NPS) promoted sport harvest and hatchery supplementation. Today, NPS management objectives focus on the preservation of native fish. We summarized management regimes of Olympic National Park's Lake Crescent, which included decades of liberal sport harvest and...
A seasonal agricultural drought forecast system for food-insecure regions of East Africa
Shraddhanand Shukla, Amy McNally, Gregory Husak, Christopher C. Funk
2014, Hydrology and Earth System Sciences (11) 3049-3081
The increasing food and water demands of East Africa's growing population are stressing the region's inconsistent water resources and rain-fed agriculture. More accurate seasonal agricultural drought forecasts for this region can inform better water and agricultural management decisions, support optimal allocation of the region's water resources, and mitigate socio-economic losses...
Effects of distributed and centralized stormwater best management practices and land cover on urban stream hydrology at the catchment scale
John V. Loperfido, Gregory B. Noe, S. Taylor Jarnagin, Dianna M. Hogan
2014, Journal of Hydrology (519) 2584-2595
Urban stormwater runoff remains an important issue that causes local and regional-scale water quantity and quality issues. Stormwater best management practices (BMPs) have been widely used to mitigate runoff issues, traditionally in a centralized manner; however, problems associated with urban hydrology have remained. An emerging trend is implementation of BMPs...
A sub-national scale geospatial analysis of diamond deposit lootability: the case of the Central African Republic
Katherine C. Malpeli, Peter G. Chirico
2014, The Extractive Industries and Society (1) 249-259
The Central African Republic (CAR), a country with rich diamond deposits and a tumultuous political history, experienced a government takeover by the Seleka rebel coalition in 2013. It is within this context that we developed and implemented a geospatial approach for assessing the lootability of high value-to-weight resource deposits, using...

Jeanne L. Hardebeck
2014, Journal of Geophysical Research B: Solid Earth (119) 8239-8266
The focal mechanisms of earthquakes in Southern California before and after four M ≥ 6.7 main shocks provide insight into how fault systems respond to stress and changes in stress. The main shock static stress changes have two observed impacts on the seismicity: changing the focal mechanisms in a given location to favor...
Catinaster virginianus sp. nov.: A new species of Catinaster from the middle Miocene Mid-Atlantic Coastal Plain
Jean M. Self-Trail
2014, Journal of Nannoplankton Research (33) 49-57
High-resolution analysis of sediments from four coreholes associated with the Chesapeake Bay impact crater has resulted in the identification of a new species, Catinaster virginianus. This species is similar to Catinaster coalitus coalitus, but differs in having a proximal stem. The first occurrence of C. virginianus is in Zone NN5, and is older...

2014, Journal of Wildlife Diseases (51) 36-47
Before the discovery of white-nose syndrome (WNS), a fungal disease caused by Pseudogymnoascus destructans, there were no reports of fungal skin infections in bats during hibernation. In 2011, bats with grossly visible fungal skin infections similar in appearance to WNS were reported from multiple sites in Wisconsin, USA, a state outside...
Transcriptomic analysis of the mussel Elliptio complanata identifies candidate stress-response genes and an abundance of novel or noncoding transcripts
Robert S. Cornman, Laura S. Robertson, Heather S. Galbraith, Carrie J. Blakeslee
2014, PLoS ONE (9)
Mussels are useful indicator species of environmental stress and degradation, and the global decline in freshwater mussel diversity and abundance is of conservation concern. Elliptio complanata is a common freshwater mussel of eastern North America that can serve both as an indicator and as an experimental model for understanding mussel...

2014, Herpetological Review (45) 41-42
Information on disease presence can be of use to natural resource managers, especially in areas supporting threatened and endangered species that occur coincidentally with species that are suspected vectors for disease. Ad hoc reports may be of limited utility (Muths et al. 2009), but a general sense of pathogen presence...
