Stable isotope ratios of carbon and nitrogen from diamondback terrapins and resources within Southern Everglades and Key West National Wildlife Refuge, sampled 2012-2013

This study was initiated to provide baseline data and to determine the utility of stable isotope analysis to evaluate the foraging strategies of an opportunistic reptile predator. Stable isotope ratios of carbon and nitrogen were evaluated from multiple tissues from terrapin populations to determine spatial or temporal variations in resource use within mangrove habitats in Southern Florida. We sampled Diamondback terrapin (Malaclemys terrapin) and potential resources within mainland and island habitats, and evaluated their δ13C and δ15N values. We fit linear regression models to determine the best predictors of isotopic values for both terrapins and their prey, and SIBER analysis to examine terrapin isotopic niche space and overlap between groups. We identified differences in terrapin isotopic δ13C and δ15N values among all sites. Blood and scute tissues revealed different isotopic compositions and niche overlap between sites, suggesting diets or foraging locations may change over time, and amount of variation is site specific. Niche overlap between size classes was larger for blood (short-term) versus scute (long-term), suggesting greater variability in food resource use and/or isotopic signal of those food resources over short and long timescales.

Salt marsh carbon dynamics under altered hydrologic regimes and elevated CO2 conditions, Louisiana, USA (2014-2015)

Plant-mediated processes are often important in determining carbon cycling and storage in ecosystems. With climate-induced changes in the environment, plant-associated processes may also shift. Salt marshes in particular are useful systems to investigate plant-mediated carbon cycling, as these systems experience both sea-level rise and increased carbon dioxide concentrations due to climate change, in addition to stochastically experiencing extreme drought and flood conditions. We measured biomass, soil, and gas carbon pools and the fluxes between those pools using a mesocosm approach in a salt marsh system, to investigate the response of plant-mediated carbon cycling to near-term climate change.

Accuracy of Rapid Crop Cover Maps of Conterminous United States for 2008 - 2016

Spatially accurate annual crop cover maps are an important component to various planning and research applications; however, the importance of these maps varies significantly with the timing of their availability. Utilizing a previously developed crop classification model (CCM), which was used to generate historical annual crop cover maps (classifying nine major crops: corn, cotton, sorghum, soybeans, spring wheat, winter wheat, alfalfa, other hay/non alfalfa, fallow/idle cropland, and ‘other’ as one class for remaining crops), we hypothesized that such crop cover maps could be generated in near real time (NRT). The CCM was trained on 14 temporal and 15 static geospatial datasets, known as predictor variables, and the National Agricultural Statistics Service (NASS) Cropland Data Layers (CDL) was used as the dependent variable. We were able to generate a NRT crop cover map by the first day of September through a process of incrementally removing weekly and monthly data from the CCM and comparing the subsequent map results with the original maps and NASS CDLs. Initially, our NRT results revealed training error of 1.4% and test error of 8.3%, as compared to 1.0% and 7.6%, respectively for the original CCM. Through the implementation of a new 'two-mapping model' approach, we were able to substantially improve the results of the NRT crop cover model. We divided the NRT model into one 'crop type model' to handle the classification of the nine specific crops and a second, binary model to classify crops as presence or absence of the ‘other’ crop. Under the two-mapping model approach, the training errors were 0.8% and 1.5% for the crop type and binary model, respectively, while test errors were 5.5% and 6.4% for crop type and binary model, respectively. With overall mapping accuracies for annual maps reaching in 60s to 70s percent, this approach shows strong potential for generating crop type maps of current year in September.

Brady Canal hydrologic restoration (TE-28): 2016 habitat classification

The Louisiana State Legislature created Coastal Wetlands Planning, Protection, and Restoration Act (CWPPRA) in order to conserve, restore, create and enhance Louisiana's coastal wetlands. The wetland restoration plans developed persuant to these acts specifically require an evaluation of the effectiveness of each coastal wetlands restoration project in achieving long-term solutions to arresting coastal wetlands loss. This data set includes mosaicked aerial photographs for the Brady Canal Hydrologic Restoration (TE-28) project for 2016. This data set is used as a basemap for habitat classification. It also serves as a visual tool for project managers to help them identify any obvious problems or land loss within their project boundary. To better evaluate the effectiveness of restoration efforts, a habitat classification is performed on specific CWPPRA sites to help assess landscape changes.

Carnivore Hotspots in Peninsular Malaysia

A raster surface identifying hotspots of conservation priority based on 375 location records (89 unique geographic locations) of 28 species of Carnivora in Peninsular Malaysia.  Hot spot analysis was conducted by calculating the Getis-Ord Gi* (pronounced G-i-star) statistic, using IUCN Red List status rank for each species as a weighting variable.  Raster cell values represent a kernel density of z-scores measuring the statistical significance of clustering or dispersion of species of conservation concern.  Areas of high clustering (high z-scores) correspond to areas on Peninsular Malaysia where carnivore communities of conservation concern are more likely to persist, and delineate priority regions for carnivore conservation.  Two identified carnivore hotspots are spatially concordant with two of the peninsula’s largest and most contiguous forest complexes (Taman Negara National Park and Royal Belum State Park).  A cold spot occurs in the southwestern region of the Peninsula.

Suspended sediment concentration and loads for the Nooksack River at Ferndale, Washington, 2012-2017 water years

Turbidity was continuously monitored at the USGS streamgage Nooksack River at Ferndale (12213100) from October 29, 2011 to September 30, 2017. A DTS-12 turbidity sensor (Forest Technology Systems) at the streamgage measured turbidity at 15-minute intervals. Suspended-sediment samples were collected at the streamgage over a range of discharge and turbidity conditions. Regression equations were developed to estimate the suspended-sediment concentration (SSC) and the concentration of fine suspended-sediment (fSSC; &lt;0.0625 mm) using turbidity as an explanatory variable. A 15-minute time series of SSC, fSSC, and the uncertainty of individual estimates (prediction intervals with 90 percent confidence) was computed and is provided. A daily time series of suspended-sediment load (SSL) and fine suspended-sediment load (fSSL), derived from either 15-minute or daily SSC and discharge data, was computed for the 2012-2017 water years.
