Wolf Population Survival In An Area Of High Road Density, L. David Mech
Wolf Population Survival In An Area Of High Road Density, L. David Mech
USGS Northern Prairie Wildlife Research Center
Wolf mortality in a high-road-density area of Minnesota exceeds that in an adjacent wilderness, and is primarily human-caused. The wolf population there is maintained primarily by ingress from the adjacent wilderness areas. A road density of 0.58 km/km2 can be exceeded and the area still support wolves if it is adjacent to extensive roadless areas.

The Status Of Erythronium Albidum And E. Mesochoreum (Liliaceae) In Nebraska, Robert B. Kaul
Transactions of the Nebraska Academy of Sciences and Affiliated Societies
Two species of Erythronium grow in the eastern quarter of Nebraska, but there are none elsewhere in the State. Erythronium albidum is locally abundant, mostly in upland bur oak forests, and has been collected in 18 counties since 1864. Erythronium mesochoreum is becoming rare because its habitat--virgin tall-grass prairie--is disappearing. It is known to grow now in six east-central counties, but it probably could be found in some remnant prairies in all counties south and east of the Platte and Big Blue rivers, respectively. Distributional data about these species is herein brought up to date relative to earlier published reports. …
