Bee-Gap: Ecology, Life-History, and Distribution of Bee Species in the United States 2017 Bee-Gap describes the ecology, life-history, and distribution of 3,925 bee species in the United States that have geographical data and verified taxonomy. The database was constructed by compiling information from a broad range of internet sources and peer-reviewed journal articles. The 10 traits included in the database are: native status (native versus exotic/introduced), state and territory presence/absence, adult habitat, nesting strategy, voltinism, sociality, host bee species (for parasitic bees only), foraging strategy (generalist vs specialist), known host plants, and tongue length.

The post glacial chronosequence includes sand dunes and moraines, representing a successional gradient from woodland transition, to oak savanna, woodland and forest, to oak hickory forests on the Lake Border Moraine. Soil samples were collected from August 24, 2017 to September 1, 2017; vegetation cover data (percent cover by species) were collected from 1/4-meter squared plots (0.5 by 0.5 m) where the soil samples were taken. DNA extracted from soil and rhizosphere samples were analyzed for bacterial communities...

The Pilot Area is a region of the northern Great Lakes Basin between Ashland, WI and the Keweenaw Peninsula and is bounded by Lake Superior in the north and the basin boundary in the south, including a 70 km buffer. Each year the TH&C selects project proposals for funding within the pilot area. These proposals involve either restoration, research, or land acquisition aimed at improving or increasing forest connectivity in this area. The intended purpose of each year’s update is to understand the effects... Tags: Connectivity, Ecology, Great Lakes, Land Use Change, Open Habitat, All tags...

Each pixel represents the relative contribution that cell provides to connectivity between and among the protected areas. When aggregated the pixel values produce a map of all possible pathways between protected areas, providing the end user with an understanding of each pathway's potential to facilitate or impede species movement. The relative contribution values are determined using the National Land Cover Dataset, where each land use pixel is converted into a value representing its resistance to movement. That is, how easy or difficult movement through that land... Tags: Ecology, Great Lakes, Land Use Change, Remote Sensing, USGS Science Data Catalog (SDC), All tags...

Soil samples were processed for standard soil chemistry, texture, and nutrients. DNA extracted from soil samples were analyzed for bacterial communities using 16S rRNA amplicon sequencing technique to understand the composition and distribution of these communities along the successional gradient. Soils samples were collected in 2015 and 2017. Vegetation data were collected only in 2017, as the vegetation was dormant in 2015. We collected the data to examine the relationships among soils, vegetation, and composition of the microbial communities along a dunal chronosequence. A dunal chronosequence is a series...
