Science to Inform Management of Floodplain Conservation Lands under Non-Stationary Conditions

Within large-river ecosystems, floodplains serve a variety of important ecological functions. A recent survey of 80 managers of floodplain conservation lands along the Upper and Middle Mississippi and Lower Missouri Rivers in the central United States found that the most critical information needed to improve floodplain management centered on metrics for characterizing depth, extent, frequency...

Change in fire probability from baseline to 2040-2069 using HadCM3-projected climate values

Globally, changing fire regimes due to climate is one of the greatest threats to ecosystems and society. This dataset presents projections of historic and future fire probability for the southcentral U.S. using downscaled climate projections and the Physical Chemistry Fire Frequency Model (PC2FM, Guyette et al., 2012). Climate data from 1900-1929 and projected climate data for 2040-2069 and...

XRF_samples_Palmyra_Atoll_2008_and_2010

Soils and organismal tissue from known and potential sources of contamination at Palmyra Atoll were measured for concentrations of 13 elements using a hand-held X-Ray Flourometer (XRF). Measured elements include; Lead (PB), Arsenic (As), Cobalt (Co), Cromium (Cr), Copper (Cu), Antimony (Sb), Iron (Fe), Titanium (Ti), Zinc (Zn), Nickel (Ni), Manganese (Mn), Sulphur (S) and Phosphorous (P)....

US_Navy_facilities_Palmyra_Atoll_1944

Data set contains individual structures and use-areas identifiable from scanned images of 1944 hand-drawn map of buildings and facilities at Palmyra Atoll during World War II, at which time the atoll served as a training facility for the U.S. Navy. Scanned images were georeferenced against control points identifiable from 2007 QuickBird satellite imagery and on control points for which...

Survival, growth and reproduction of the amphipod Hyalella azteca in 42-d water only treatments with and without the addition of bromide

Poor survival, growth and reproduction of the amphipod Hyalella azteca has been observed in exposures using reconstituted waters. Previous studies have reported success in H. azteca water-only exposures with the addition of relatively high concentrations of bromide (Br). This study evaluated the influence of lower environmentally representative concentrations of Br on the response of the...
