Introduction Seiridium cardinale (Wagener) Sutton et Gibson has been wrecking havoc on populations of cypress (particularly Cupressus macrocarpa and C. sempervirens) since its discovery in California in 1927 and its spread to Europe shortly thereafter (Raddi and Panconesi 1981; Wagener 1928). In the 1920’s, disease symptoms in C. macrocarpa were originally attributed to insects (Wagener 1928). Wagener officially identified the causal agent as Coryneum cardinale in 1939, though Sutton and Gibson
Introduction Bucculatrix ainsliella Murtfeldt is a skeletonizing species of Lepidoptera that can cause excessive damage to both forest and urban environments. Causal Agent The Oak Leaf Skeletonizer, Bucculatrix ainsliella is in the order Lepidoptera, which categorizes it as a defoliator in its larval stages (Gelok et al. 1998; Klass 1985; Van Nieukerken et al. 2012). It is a native species to Eastern United States and was once limited to Southern Canada and the Eastern coast of the United States
1. The biodiversity hotspot I choose to write about is the California Floristic Province. 2. The California Floristic Province is located in United States, mainly, in the state of California, reaching Oregon and northern Mexico (BBC, 2004). 3. One important species the live in the California Floristic Province is the Aloe adigratana (it has no common name). According to circumstantial evidence, it has been used as medicine. Another use of this plant is as a boundary fence. (Weber & Demissew, 2013)
Olympic National Park is a diverse ecosystem with 922,651 acres of wilderness, which include 60 glaciers, 13 rivers, 57 miles of coastline, over 600 miles of hiking trails and the largest herd of Roosevelt elk (Cervus canadensis roosevelti) in America. Olympic National Park ecosystems include subalpine forest, meadows, temperate rain forest, and the Pacific coastline; making this a diverse ecosystem. Because of the variety of elevations climate will vary, during october to march temperature will
The equation on the page of his scribbler began to spread out a widening tail, eyed and starred like a peacock's; and, when the eyes and stars of its indices had been eliminated, began slowly to fold itself together again. The indices appearing and disappearing were eyes opening and closing; the eyes opening and closing were stars being born and being quenched. The vast cycle of starry life bore his weary mind outward to its verge and inward to its centre, a distant music accompanying him outward
Alzheimer’s disease (AD) is a cognitive neurodegerative disorder and one of the major forms of dementia; it represents 60-80% of the dementia patients (Barker et at., 2002). It is estimated by the end of 2015, 53 million people of America would be affected and this would almost double by 2025 and triple by 2050, hence making research momentous for the cure (Hebert et al., 2013). It takes almost 8.5 years between the onset of symptoms of the disease and death (Francis, Palmer, Snape et al., 1998)
Some environmental problems in Viet Nam today Thai Cong Tung Abstracts Demographic growth, urbanization, industrialization, infrastructure development...are contributing to increase stress on the natural resource base in Viet Nam today. The paper highlighted those stresses : the rural exodus to the cities due to scarce land resources in the countryside, the pollution problems in the urban environment, the migration of people to forested areas with direct impacts including the deforestation, the watershed
