  Fungi-filled forests are critical for endangered orchids

  ScienceDaily (Jan. 24, 2012) ? When it comes to conserving the world’s orchids, not all forests are equal. In a paper to be published Jan. 25 in the journal Molecular Ecology, Smithsonian ecologists revealed that an orchid’s fate hinges on two factors: a forest’s age and its fungi. Roughly 10 percent of all plant species are orchids, making them the largest plant family on Earth. But habitat loss has rendered many threatened or endangered. This is partly due to their intimate relationship with the soil. Orchids depend entirely on microscopic fungi in the early stages of their lives. Without the nutrients orchids obtain by digesting these host fungi, their seeds often will not germinate and baby orchids will not grow. While researchers have known about the orchid-fungus relationship for years, very little is known about what the fungi need to survive. Biologists based at the Smithsonian Environmental Research Center launched the first study to find out what helps the fungi flourish and what that means for orchids. Led by Melissa McCormick, the researchers looked at three orchid species, all endangered in one or more U.S. states. After planting orchid seeds in dozens of experimental plots, they also added particular host fungi needed by each orchid to half the plots. Then they followed the fate of the orchids and fungi in six study sites: three in younger forests (50 to 70 years old) and three in older forests (120 to 150 years old). After four years they discovered orchid seeds germinated….

  Too Few Americans Getting Screened for Common Cancers: CDC (HealthDay)

  THURSDAY, Jan. 26 (HealthDay News) — The number of Americans being screened for colon, breast and cervical cancers still fall below national targets, federal health officials said Thursday. In 2010, 72.4 percent of women were being screened for breast cancer, below the target of 81 percent, for cervical cancer it was 83 percent of women, while the target is 93 percent, and for colon cancer 58.6 percent of Americans were screened, missing the target of 70.5 percent, according to the U.S. Centers for Disease Control and Prevention. “Not all Americans are getting the recommended screening for breast, cervical and colorectal cancer,” said report co-author Mary C. White, branch chief of the CDC’s Division of Cancer Prevention and Control. “There continue to be disparities for certain populations.” The screening rates are particularly low among Asians and Hispanics, according to the report in the Jan. 27 issue of Morbidity and Mortality Weekly Report. Among Asians, the screening rate for breast cancer was 64.1 percent, for cervical cancer it was 75.4 percent, and for colon cancer it was 46.9 percent. Hispanics were less likely than non-Hispanics to have screening for cervical and colon cancer (78.7 percent and 46.5 percent, respectively), the researchers found. Screening is important, said Dr. Stephanie Bernik, chief of surgical oncology at Lenox Hill Hospital in New York City. “Screening saves lives,” she said. “When you catch a cancer at a smaller size it does affect outcome.” Some people may be confused about screening, because different medical groups have different….
