Perhaps this is due to the pear tree 's reputation for becoming very large , for its history of susceptibility to fire blight disease , or the fact that varieties hardy to our region do not include the well-known and popular ' Bartlett ' or ' Bosc . Schlenter and VanCleve ( 1985 ) have shown that rates of aerobic decomposition in black spruce forests are directly proportional to both temperature and soil moisture . Conducted in the mid 1990s , this trial recruited 6595 men with high LDL cholesterol levels but with no history of heart disease to undergo a test of the drug pravastatin which is produced by Bristol Myers Squib Company . Example applications include measurement of Greenland and Antarctic ice-sheet elevations ( Thomas et al ., 1992 ; Blankenship et al ., 1993 ) , outlet glacier strains and shape changes due to surge events ( Garvin and Williams , 1993 ; Garvin et al ., in revision ) , and the structural properties of vegetation canopy , such as tree height and biomass ( Aldred and Bonnor , 1985 ; Nelson et al ., 1988 a , b ) . In the early days of the University the Rector was its active Head but for several centuries , until modern times , the post was honorific and successful candidates included Gladstone , Disraeli , Balfour , Bonar Law , and the French President , Poincare . The varieties we purchase at the grocery store — ' Bartlett , ' ' Bosc , ' and the pricey Asian pears — are not hardy here .
