Araucaria angustifolia (Bert.) O. Ktze., a native forest tree from Brazil, is under extinction risk. This tree depends on arbuscular mycorrhizal fungi for growth and development, especially in tropical low-P soils but, despite being a conifer, Araucaria does not form ectomycorrhiza, but only the arbuscular endomycorrhiza. This study aimed at surveying data on the spore density and root coloniza...

The 1990s were remarkably good to U.S. stockholders. Stock returns for the decade averaged 16.1 percent per year, almost twice the historical average of 8.7 percent. The decade began modestly enough, yielding a 5.9 percent annual return to equity from 1990 to 1995, but it f inished exceptionally strong, with an astonishing 26.3 percent average annual return from 1996 to 1999. As returns mounted...

One hundred thirty-three Streptococcus milleri group (S. anginosus) isolates were recovered from 487 surgical patients. The streptococci were recovered from 33 percent of intra-abdominal infection cultures (84/257). 22 percent of samples from penetrating visceral trauma (19/86), 52 percent of perirectal abscess specimens (13/25), 13 percent of nonpuerperal breast abscess cultures (8/60), and 15...
