Human assisted plant invasions from Europe to North America have been more common than the reverse. We tested endophyte-mediated performance of tall fescue in parallel three year experiments in Europe and the USA using endophyte infected and uninfected wild and cultivated plants. Experimental plants were subjected to nutrient and water treatments. Whereas endophyte infection increased tall fescue performance in general, the effects of endophytes on plant growth and reproduction varied among plant origins under different environmental conditions. Naturally endophyte-free Finnish cultivar ‘Retu’ performed equally well as ‘Kentucky-31’ in both geographic locations. All Eurasian origin plants performed well in the US. …

Heavy-Oil And Bitumen Resources Of The Big Clifty Sandstone, Northeastern Grayson County And Adjacent Hardin County, Kentucky, J. Richard Bowersox
Report of Investigations--KGS
Rock asphalt (bitumen-saturated sandstone) was produced from the Big Clifty Sandstone near Tar Hill and Big Clifty in northeastern Grayson County, and at Summit in adjacent Hardin County, from 1889 to 1940. Noncommercial amounts of oil were distilled from Big Clifty rock asphalt before 1930. Resource assessments conducted throughout the area during the mid-1920's described substantial rock-asphalt deposits. Later assessments in 1951, 1965, and the early 1980's, however, overlooked the northeastern Grayson County area. A new evaluation in 2015 estimated that the historically developed area between Clifty Creek and meeting Creek, and between the Summit Fault and Eveleigh Fault Zone, …
