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...
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...

Coggins Jr., Michael D. Yard
2011, Fact Sheet 2011-3093
The humpback chub (Gila cypha) is an endangered native fish found only in the Colorado River Basin. In Grand Canyon, most humpback chub are found in the Little Colorado River and its confluence with the Colorado River. For decades, however, nonnative rainbow trout (Oncorhynchus mykiss) and brown trout (Salmo trutta),...

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...

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...
Annual peak streamflow and ancillary data for small watersheds in central and western Texas
Glenn R. Harwell, William H. Asquith

Deglaciation and postglacial treeline fluctuation in the northern San Juan Mountains, Colorado
Paul E. Carrara
2011, Professional Paper 1782
The San Juan Mountains of southwestern Colorado contain numerous lakes and bogs at and above treeline. In June 1978, Lake Emma, a tarn above present-day treeline, was suddenly drained by the collapse of underground mine workings. This study was initiated because the draining exposed a well-preserved archive of subfossil coniferous...
