Multispecies modeling for adaptive management of horseshoe crabs and red knots in the Delaware Bay
Conor P. McGowan, David R. Smith, J. A. Sweka, Julien Martin, James D. Nichols, R. Wong, J. E. Lyons, L. J. Niles, K. Kalasz, J. Brust, M. Klopfer, B. Spear
2011, Natural Resource Modeling (24) 117-156
Adaptive management requires that predictive models be explicit and transparent to improve decisions by comparing management actions, directing further research and monitoring, and facilitating learning. The rufa subspecies of red knots (Calidris canutus rufa), which has recently exhibited steep population declines, relies on horseshoe crab (Limulus polyphemus) eggs as their...
Estimating age from recapture data: Integrating incremental growth measures with ancillary data to infer age-at-length
Mitchell J. Eaton, William A. Link
2011, Ecological Applications (21) 2487-2497
Estimating the age of individuals in wild populations can be of fundamental importance for answering ecological questions, modeling population demographics, and managing exploited or threatened species. Significant effort has been devoted to determining age through the use of growth annuli, secondary physical characteristics related to age, and growth models. Many...
Structured decision making as a proactive approach to dealing with sea level rise in Florida
J. Martin, P.L. Fackler, James D. Nichols, B. C. Lubow, Mitchell J. Eaton, Michael C. Runge, Bradley Stith, Catherine A. Langtimm
2011, Climatic Change (107) 185-202
Sea level rise (SLR) projections along the coast of Florida present an enormous challenge for management and conservation over the long term. Decision makers need to recognize and adopt strategies to adapt to the potentially detrimental effects of SLR. Structured decision making (SDM) provides a rigorous framework for the management...
Analysis of the North American Breeding Bird Survey using hierarchical models
John R. Sauer, William Link
2011, The Auk (128) 87-98
We analyzed population change for 420 bird species from the North American Breeding Bird Survey (BBS) using a hierarchical log-linear model and compared the results with those obtained through route-regression analysis. Survey-wide trend estimates based on the hierarchical model were generally more precise than estimates from the earlier analysis. No...

Chemical, mineralogic, and lithologic ground truth was acquired for the first time on Mars in terrain units mapped using orbital Mars Reconnaissance Orbiter's High Resolution Imaging Science Experiment (MRO HiRISE) image data. Examination of several dozen outcrops shows that Mars is geologically complex at meter length scales, the record of...
Fire and vegetation shifts in the Americas at the vanguard of Paleoindian migration
N. Pinter, S. Fiedel, Jon E. Keeley
2011, Quaternary Science Reviews (30) 269-272
Across North and South America, the final millennia of the Pleistocene saw dramatic changes in climate, vegetation, fauna, fire regime, and other local and regional paleo-environmental characteristics. Rapid climate shifts following the Last Glacial Maximum (LGM) exerted a first-order influence, but abrupt postglacial shifts in vegetation composition, vegetation structure, and...
Timing constraints on remote sensing of wildland fire burned area in the southeastern US
Joshua J. Picotte, Kevin Robertson
2011, Remote Sensing (3) 1680-1690
Remote sensing using Landsat Thematic Mapper (TM) satellite imagery is increasingly used for mapping wildland fire burned area and burn severity, owing to its frequency of collection, relatively high resolution, and availability free of charge. However, rapid response of vegetation following fire and frequent cloud cover pose challenges to this...
Developmental rate and behavior of early life stages of bighead carp and silver carp
Duane Chapman, Amy E. George
2011, Scientific Investigations Report 2011-5076
The early life stages of Asian carp are well described by Yi and others (1988), but since these descriptions are represented by line drawings based only on live individuals and lacked temperature controls, further information on developmental time and stages is of use to expand understanding of early life stages...

Travis S. Schmidt, William H. Clements, Robert E. Zuellig, Katharine A. Mitchell, Stan E. Church, Richard B. Wanty, Carma A. San Juan, Monique Adams, Paul J. Lamothe
2011, Environmental Science & Technology (45) 7004-7010
Whole body Zn concentrations in individuals (n = 825) from three aquatic insect taxa (mayflies Rhithrogena spp. and Drunella spp. and the caddisfly Arctopsyche grandis) were used to predict effects on populations and communities (n = 149 samples). Both mayflies accumulated significantly more Zn than the caddisfly. The presence/absence of Drunella spp. most reliably distinguished sites with low and...

Chemical and microbiological analyses of water from 230 wells and 35 springs in the Valley and Ridge Physiographic Province, sampled between 1993 and 2002, indicated that bedrock type (carbonate or siliciclastic rock) and land use were dominant factors influencing groundwater quality across a region extending from northwestern Georgia to New...
Human casualties in earthquakes: Modelling and mitigation
R.J.S. Spence, E.K.M. So
2011, Conference Paper, Proceedings of the Ninth Pacific Conference on Earthquake Engineering: Building an earthquake resilient society
Earthquake risk modelling is needed for the planning of post-event emergency operations, for the development of insurance schemes, for the planning of mitigation measures in the existing building stock, and for the development of appropriate building regulations; in all of these applications estimates of casualty numbers are essential. But there...

David H. Bennion, Bruce A. Manny
2011, Scientific Investigations Report 2011-5122
The Detroit River is one of the most biologically diverse areas in the Great Lakes basin. It has been an important international shipping route since the 1820s and is one of the busiest navigation centers in the United States. Historically, it supported one of the most profitable Lake Whitefish (Coregonus...
Annual peak streamflow and ancillary data for small watersheds in central and western Texas
Glenn R. Harwell, William H. Asquith
2011, Fact Sheet 2011-3082
Estimates of annual peak-streamflow frequency are needed for flood-plain management, assessment of flood risk, and design of structures, such as roads, bridges, culverts, dams, and levees. Regional regression equations have been developed and are used extensively to estimate annual peak-streamflow frequency for ungaged sites in natural (unregulated and rural or...
