atomic number 20 bay medallions in serpentine blemish are more resistant to sudden Oak Death
Sudden Oak Death (SOD), a disease caused by the pathogen genus Phytophthora ramorum, is an increasing environmental issue since it was discovered in California in 1995. Today, 17 years later SOD has reached pestilential proportions especially up the coastal regions of central California and Confederate Oregon. Sonoma County has been greatly affected by SOD because its environment is prospered by the pathogen. The horrifying factor is that very few plenty know about this disease and therefore very midget is known. As this issue is slowly increasing in popularity, P ramorum is spreading extraordinarily fast infecting and killing over 20 different species and 12 plant families loosely in coniferous and Redwood forests (Rizzo et al. 2002b; Garbelotto et al. 2003.) This pathogen has greatly affected the environment and the ecosystem of this area. The dead and anxious(p) trees are affecting the wild animal life that relies on these trees for food or survival, along with increasing hazards such as: injuries, death, and property damage and fire rates.
The origin of P ramorum is cool off unknown, however it appears to be present in Europe as well. In 1993, P ramorum was recovered in dead and decease Rhododendrons and Viburnums in Germany and the Netherlands.



Later studies on the mating types of European and American P ramorum species states that the pathogen may have originated in a third gear unknown location and then transported from there. It is also known that the pathogen mostly favors tan oaks (Lithocarpus denisflora), coast live oak (Quercus agrifolia), California black oak (Quercus kellogii), Shreves oak (Quercus parvula var shrevei), and even California bay laurel (Umbellularia Californica) in Northern California.
Phytophthora Ramorum is a fungal equal pathogen because it produces hyphae and spores, but it also has protistal characteristics since it has a cell wall and is diploid. P. Ramorum favors hard and wet...If you want to get a full essay, order it on our website: Orderessay
