2001), and large clear-cut areas also encourage competitive species to move in and displace goshawks from established nesting areas (Erdman et al 1998, La Sorte et al. 2004). Goshawks appear to select late-successional forest stands for nesting (e.g., Reynolds et al. 1982).he Federal BBS information can be obtained at http://www.mbr-pwrc.usgs.gov/bbs/bbs.html by clicking on Trend Estimates and selecting the species in question. All estimates are for time period (1966-2005).
Mycoplasma hyopneumoniae. Mycoplasma hyopneumoniae is a species of bacteria known to cause the disease porcine enzootic pneumonia, a highly contagious and chronic disease affecting pigs. As with other mollicutes, M. hyopneumoniae is small in size (400â1200 nm), has a small genome (893â920 kilo-base pairs (kb)) and lacks a cell wall.
In 1898, Nocard and Roux were the first to isolate a mycoplasma species in culture from bovine; however, it was not until 1944 when Mycoplasma pneumoniae, known then as Eaton agent or Eaton's agent, was isolated and described from a patient with primary atypical pneumonia.
