AmeriFlux ecosystem observation datasets - Walnut Gulch Experimental Watershed - Kendall Grasslands

NAL Geospatial Catalog

Energy and CO2 Fluxes have been monitored from 1997 to 2007 using Bowen Ratio technique, and since spring of 2004 with eddy covariance. This is located in a small intensively-studied, experimental watershed within USDA-ARS's Walnut Gulch Experimental Watershed.

Ameriflux data: Goodwin Creek, Mississippi, 1980-2014

NAL Geospatial Catalog

This dataset links to a data download from the Daymet website. Data parameters are Latitude: 34.2547 Longitude: -89.8735 X & Y on Lambert Conformal Conic: 897941.75 -822030.73; Tile: 11206; Elevation: 91 meters; Years: 1980-2014. Archived and distributed through the Oak Ridge National Laboratory Distributed Active Archive Center (ORNL DAAC), the Daymet dataset for Goodwin Creek provides gridded estimates of daily weather parameters for North America, including daily continuous surfaces of minimum and maximum temperature, precipitation occurrence and amount, humidity, shortwave radiation, snow water equivalent, and day length.

AmeriFlux ecosystem observation datasets - University of Nebraska, Lincoln, Agricultural Research Service rainfed maize-soybean rotation site

NAL Geospatial Catalog

The study site is one of three fields (all located within 1.6 km of each other) at the University of Nebraska Agricultural Research and Development Center near Mead, Nebraska. While the other two sites are equipped with irrigation systems, this site relies on rainfall. A tillage operation (disking) was done just prior to the 2001 planting to homogenize the top 0.1 m of soil, incorporate P and K fertilizers, as well as previously accumulated surface residues. Since initiation of the study in 2001, this site has been under no-till management.

Data from: Late Glacial and Holocene records of tree-killing conifer bark beetles in Europe and North America: Implications for forest disturbance dynamics

This study identifies existing fossil records containing bark beetle remains from the end of the Last Glacial Maximum (~14,000 cal. yr BP) to present day using the online databases Neotoma and BugsCEP and literature searches, and compares these data with modern distribution data of selected tree-killing species.

Data from: Phylogeography of the Wheat Stem Sawfly, Cephus cinctus Norton (Hymenoptera: Cephidae): Implications for Pest Management

The wheat stem sawfly is a key pest of wheat in the northern Great Plains of North America, and damage resulting from this species has recently expanded southward. The genetic divergence between samples collected in North America and northeastern Asia using two mitochondrial regions (COI and 16S) are examined. The structure of genetic diversity in the main wheat producing areas in North America are also characterized using a combination of mtDNA marker and microsatellites in samples collected both in wheat fields and in grasses in wildlands.

Data from: Global distribution of mating types shows limited opportunities for mating across populations of fungi causing boxwood blight disease

Boxwood blight is a disease threat to natural and managed landscapes worldwide. To determine mating potential of the fungi responsible for the disease, *Calonectria pseudonaviculata* and *C. henricotiae*, we characterized their mating-type (MAT) loci. Genomes of *C. henricotiae*, *C. pseudonaviculata* and two other *Calonectria* species (*C. leucothoes*, *C. naviculata*) were sequenced and used to design PCR tests for mating-type from 268 isolates collected from four continents.
