This data release includes data and metadata containing (1) study site locations and elevation where bolts (tree stem sections) infected with Ceratocystis lukuohia and/or C. huliohia were collected on Hawai'i Island, (2) the ambrosia beetle (Coleoptera: Scolytinae) species that were reared from bolts, (3) Ceratocystis spp. viability results from culturing tests of the beetles' frass, (4)...
40Ar/39Ar Isotopic Data and Ages for Rocks from the Yukon-Tanana Upland of Eastern Alaska and the Northern Aleutian Range of South-Central Alaska 40Ar/39Ar Isotopic Data and Ages for Rocks from the Yukon-Tanana Upland of Eastern Alaska and the Northern Aleutian Range of South-Central Alaska
This dataset contains 40Ar/39Ar isotopic data and ages for rocks from the Yukon-Tanana upland of eastern Alaska and the northern Aleutian Range of south-central Alaska. The entire sample suite was collected as part of geological mapping and supporting geochemical and geochronological analysis were conducted from 2013 to 2019 by the Mineral Resources Program of the U.S. Geological Survey...
Data for Determining Age of Barrow's Goldeneye (Bucephala islandica) from External Characteristics, Alaska and Canada, 2007-2015 Data for Determining Age of Barrow's Goldeneye (Bucephala islandica) from External Characteristics, Alaska and Canada, 2007-2015
These data describe an exercise in which known age and sex class of 100 Barrow's goldeneyes (Bucephala islandica), determined by expert examination bursa and plumage, was contrasted with age and sex classes estimated from photos by trained observers.
Discharge, nutrient, and suspended sediment data for selected streams in the Lake Tahoe watershed Discharge, nutrient, and suspended sediment data for selected streams in the Lake Tahoe watershed
A time series of nutrient and mean daily discharge data were used to create models of daily concentration and loads for selected streams of the Lake Tahoe watershed. A total of 15 sites have records ranging from as early as 1972 to 2017. Nutrients in the data set include nitrate, ammonium, Kjeldahl Nitrogen, orthophosphate, and total phosphorus. Total suspended sediment concentrations...
Pre- and Post-Treatment Fuels and Vegetation Data from the Great Basin, 2006-2018 (ver. 2.0, September 2020) Pre- and Post-Treatment Fuels and Vegetation Data from the Great Basin, 2006-2018 (ver. 2.0, September 2020)
The project was conducted to study the effects of land management options. It was conducted across a regional network of sites in sagebrush communities. Using this regional network of sites allowed us to understand the thresholds between healthy and unhealthy sagebrush communities over a broad range of conditions across the Great Basin. Sites were located in sagebrush communities...
