Coupling at Mauna Loa and Kīlauea by stress transfer in an asthenospheric melt layer
Helge M. Gonnermann, James H. Foster, Michael Poland, Cecily J. Wolfe, Benjamin A. Brooks, Asta Miklius
2012, Nature Geoscience (5) 826-829
The eruptive activity at the neighbouring Hawaiian volcanoes, Kīlauea and Mauna Loa, is thought to be linked despite both having separate lithospheric magmatic plumbing systems. Over the past century, activity at the two volcanoes has been anti-correlated, which could reflect a competition for the same magma supply. Yet, during the...
Summer temperature metrics for predicting brook trout (Salvelinus fontinalis) distribution in streams
Donna L. Parrish, Ryan S. Butryn, Donna M. Rizzo
2012, Hydrobiologia (703) 47-57
We developed a methodology to predict brook trout (Salvelinus fontinalis) distribution using summer temperature metrics as predictor variables. Our analysis used long-term fish and hourly water temperature data from the Dog River, Vermont (USA). Commonly used metrics (e.g., mean, maximum, maximum 7-day maximum) tend to smooth the data...

Fred F. Pollitz, Ross S. Stein, Volkan Sevilgen, Roland Burgmann
2012, Nature (490) 250-253
Large earthquakes trigger very small earthquakes globally during passage of the seismic waves and during the following several hours to days1, 2, 3, 4, 5, 6, 7, 8, 9, 10, but so far remote aftershocks of moment magnitude M≥5.5 have not been identified11, with the lone exception of an M=6.9...

2012, Scientific Investigations Report 2012-5115
Mercury in soils, surface water, and groundwater at the William J. Hughes Technical Center , Atlantic County, New Jersey, has been found at levels that exceed established background concentrations in Coastal Plain waters, and, in some cases, New Jersey State standards for mercury in various media. As of 2012, it...

2012, Open-File Report 2012-1190
The Stanardsville 7.5-minute quadrangle is located about 30 kilometers north of Charlottesville, Virginia, in the eastern foothills of the Blue Ridge and within the Blue Ridge physiographic province. The quadrangle contains a small part of the eastern margin of Shenandoah National Park along Saddleback Mountain just north of Swift...
Plant allocation of carbon to defense as a function of herbivory, light and nutrient availability
Donald L. DeAngelis, Shu Ju, Rongsong Liu, John P. Bryant, Stephen A. Gourley
2012, Theoretical Ecology (5) 445-456
We use modeling to determine the optimal relative plant carbon allocations between foliage, fine roots, anti-herbivore defense, and reproduction to maximize reproductive output. The model treats these plant components and the herbivore compartment as variables. Herbivory is assumed to be purely folivory. Key external factors include nutrient availability, degree of...

All cited voucher specimens are deposited at...
Extinction rates in North American freshwater fishes, 1900-2010
Noel M. Burkhead
2012, BioScience (62) 798-808
Widespread evidence shows that the modern rates of extinction in many plants and animals exceed background rates in the fossil record. In the present article, I investigate this issue with regard to North American freshwater fishes. From 1898 to 2006, 57 taxa became extinct, and three distinct populations were extirpated...
Passive thermal refugia provided warm water for Florida manatees during the severe winter of 2009-2010

2012, Marine Ecology Progress Series (462) 287-301
Haloclines induced by freshwater inflow over tidal water have been identified as an important mechanism for maintaining warm water in passive thermal refugia (PTR) used by Florida manatees Trichechus manatus latirostris during winter in extreme southwestern Florida. Record-setting cold during winter 2009–2010 resulted in an unprecedented number of manatee deaths,...
Discordant introgression in a rapidly expanding hybrid swarm
Jessica L. Ward, Mike J. Blum, David M. Walters, Brady A. Porter, Noel Burkhead, Byron Freeman
2012, Evolutionary Applications (5) 380-392
The erosion of species boundaries can involve rapid evolutionary change. Consequently, many aspects of the process remain poorly understood, including the formation, expansion, and evolution of hybrid swarms. Biological invasions involving hybridization present exceptional opportunities to study the erosion of species boundaries because timelines of interactions and outcomes are frequently...
Bird populations on the Island of Tinian: persistence despite wholesale loss of native forests
Richard J. Camp, Frederick A. Amidon, Ann P. Marshall, Thane K. Pratt
2012, Pacific Science (66) 283-298
Bird habitat on the island of Tinian, Mariana Islands, has been substantially altered, and only around 5% of the island has native forest today. The modern bird fauna is likely to be a subset of the original avifauna where only species tolerant to native forest loss and human disturbance have...
Diet and conservation implications of an invasive chameleon, Chamaeleo jacksonii (Squamata: Chamaeleonidae) in Hawaii
Fred Kraus, Arthur Medeiros, David Preston, Catherine S. Jarnevich, Gordon H. Rodda
2012, Biological Invasions (14) 579-593
We summarize information on current distribution of the invasive lizard Chamaeleo jacksonii and predict its potential distribution in the Hawaiian Islands. Potential distribution maps are based on climate models developed from known localities in its native range and its Hawaiian range. We also present results of analysis of stomach contents...
Rapid invasion of the Indo-Pacific lionfishes (Pterois volitans and Pterois miles) in the Florida Keys, USA: evidence from multiple pre-and post-invasion data sets
Benjamin I. Ruttenberg, Pamela J. Schofield, J. Lad Akins, Alejandro Acosta, Michael W. Feeley, Jeremiah Blondeau, Steven G. Smith, Jerald S. Ault
2012, Bulletin of Marine Science (88) 1051-1059
Over the past decade, Indo-Pacific lionfishes, Pterois volitans (Linnaeus, 1758) and Pterois miles (Bennett, 1828), venomous members of the scorpionfish family (Scorpaenidae), have invaded and spread throughout much of the tropical and subtropical northwestern Atlantic Ocean and Caribbean Sea. These species are generalist predators of fishes and invertebrates with the...
Ecology and conservation biology of avian malaria
Dennis A. LaPointe, Carter T. Atkinson, Michael D. Samuel
2012, Annals of the New York Academy of Sciences (1249) 211-226
Avian malaria is a worldwide mosquito-borne disease caused by Plasmodium parasites. These parasites occur in many avian species but primarily affect passerine birds that have not evolved with the parasite. Host pathogenicity, fitness, and population impacts are poorly understood. In contrast to continental species, introduced avian malaria poses a substantial...
Eastern mosquitofish resists invasion by nonindigenous poeciliids through agonistic behaviors
Kevin A. Thompson, Jeffrey E. Hill, Leo G. Nico
2012, Biological Invasions (14) 1515-1529
Florida is a hotspot for nonindigenous fishes with over 30 species established, although few of these are small-bodied species. One hypothesis for this pattern is that biotic resistance of native species is reducing the success of small-bodied, introduced fishes. The eastern mosquitofish Gambusia holbrooki is common in many freshwater habitats...
Estimating pesticide sampling rates by the polar organic chemical integrative sampler (POCIS) in the presence of natural organic matter and varying hydrodynamic conditions
Lucner Charlestra, Aria Amirbahman, David L. Courtemanch, David A. Alvarez, Howard Patterson
2012, Environmental Pollution (169) 98-104
The polar organic chemical integrative sampler (POCIS) was calibrated to monitor pesticides in water under controlled laboratory conditions. The effect of natural organic matter (NOM) on the sampling rates (Rs) was evaluated in microcosms containing -1 of total organic carbon (TOC). The effect of hydrodynamics was studied by...
The driving forces of land change in the Northern Piedmont of the United States
Roger F. Auch, Darrell E. Napton, Steven Kambly, Thomas R. Moreland Jr., Kristi Sayler
2012, Geographical Review (102) 53-75
Driving forces facilitate or inhibit land-use/land-cover change. Human driving forces include political, economic, cultural, and social attributes that often change across time and space. Remotely sensed imagery provides regional land-change data for the Northern Piedmont, an ecoregion of the United States that continued to urbanize after 1970 through conversion of...
