DM cases. Hybridizations were performed using commercially available RREB1/ MYB/CCND1 probes and established diagnostic cutoffs. For literature review of test performance in conventional melanoma we performed pubmed searches in combination with manual review of references and tabulated the number of abnormal vs. tested cases for each probe and overall sensitivity comparisons. Routine test performance measures were calculated and statistical signifi cance was defi ned as P<0.05. Results: We performed a total of 123 hybridizations in 15 SM, 4 mixed and 14 DM cases. The assay was overall 88% sensitive (n=29 true positives). Although the sensitivity in DM was substantially lower (10/14=71% DM whereas 18/19=95% SM or 304/360=84% conventional melanoma), the differences did not reach statistical signifi cance (P-range=0.14-1.0; Chi-square). Sensitivity by individual probesets was RREB1 (24/32=75%), MYB (10/27=37%) and CCND1 (6/29=21%). Due to the relatively high sensitivity of RREB1, our results indicate that a consecutive FISH-testing algorithm (Figure 1) can drastically reduce the number of hybridizations (i.e., from n=123 to n=57). Conclusions: The triple FISH assay employing RREB1, MYB and CCND1 probe sets is highly sensitive (88%) in SM/DM. We provide evidence for a practically effi cient consecutive testing algorithm (Figure 1). Notably, the relatively high false negative rate in DM underscores the need for an additional reliable confi rmatory melanoma assay and emphasizes the biological differences in this melanoma subtype.

In 1990, the U.S. Forest Service began a fouryear project to rehabilitate and expand recreational areas at Lost Lake, an area that has been a campground since 1900. Located just east of the Cascade Range crestline at 957 m above sea level, the project area receives 406 cm (160 inches) of precipitation a year, usually in the form of snow. The prevalent vegetation can be described as belonging to the Pacific silver fir (Abies) plant community. The project objective calls for building or reconstructing 133 campsites and 32 day-use sites along with over 4.8 km of roadway. Revegetation is integrated into the construction schedule since the area is accessible only from May through October. Our revegetation goals are 1) to minimize the area disturbed by construction and to salvage as many plants as possible within those areas; 2) to replant all disturbed areas using propagules collected on-site or from adjacent clearcuts; and 3) to protect the integrity of the identified plant subcommunities. Using a classification system developed in The Plant Association and Management Guide for the Pacific Silver Fir Zone (Hemstrom et al 1986), we identified four distinct plant sub-communities within the project area ranging from hydric to xeric. Data about vegetation, environment, and soil characteristics helped us develop a site plan, vegetation management plan, and revegetation specifications. We also used plant succession field data collected from adjacent clearcuts to determine the desired species composition and spacing for replanting. We planned all the work for this multi-year project by preparing revegetation specifications and requirements in the construction contract. Service crews, temporary employees and volunteers were then trained to carry out plant salvage, seed collection and propagation tasks. Each year, in the early spring before road construction begins, workers salvage most plant materials within the construction zone. They dig 10 to 15.25-cm-thick mats of pioneer grasses/forbs and transplant them directly into high-impact areas like
1990年，美国林务局开始了一项为期四年的项目，以恢复和扩大失落湖的休闲区，该地区自1900年以来一直是露营地。位于喀斯喀特山脉峰顶线以东，海拔957米，项目区每年降雨量为406厘米(160英寸)，通常以雪的形式出现。主要植被可描述为属于太平洋银杉(冷杉)植物群落。该项目的目标是建造或重建133个营地和32个日间使用场地，以及超过4.8公里的道路。由于该地区仅在5月至10月期间开放，因此植被恢复被纳入了建设计划。我们的植被恢复目标是:1)尽量减少受建筑干扰的面积，并在这些区域内抢救尽可能多的植物;2)利用在现场或邻近采伐地收集的繁殖体，重新种植所有受干扰地区;3)保护已鉴定植物亚群落的完整性。利用《植物协会和太平洋银杉区管理指南》(Hemstrom et al . 1986)中开发的分类系统，我们在项目区域内确定了四个不同的植物亚群落，从水系到干旱区。关于植被、环境和土壤特征的数据帮助我们制定了场地规划、植被管理计划和植被恢复规范。我们还利用从邻近砍伐地收集的植物演替数据来确定所需的物种组成和补种间距。我们通过在施工合同中准备植被规格和要求来规划这个多年项目的所有工作。然后对服务人员、临时雇员和志愿者进行培训，以执行植物抢救、种子收集和繁殖任务。每年，在道路施工开始前的早春，工人们都会在施工区内打捞大部分植物材料。他们挖出10到15.25厘米厚的先驱草/植物垫，并将它们直接移植到高影响地区，如

: In order to relieve the effects of stand ages and densities on litter nutrients changes and its returns in planted Pinus massoniana forests, we selected four forest types of stand ages (Young stand, Half-mature stand, Mature stand, and Over-mature stand) and four forest types of stand densities (Low density, Middle-low density, Middle-high density, and High density) as the research object (total 8 stands) in Zhenlong Forest Farm of Hengxian County, Nanning, Guangxi Zhuang Autonomous Region; and we measured litter carbon, nitrogen and phosphorus contents and its ratios in the early and latter degradation period of litter. The results were as follows: (1) C contents in early degradation period of litter were relatively higher in Mature and Over-mature stands, N contents were relatively higher in Over-mature and Half-mature stands, but P contents and N:P ratios were not different among four stands, C:N and C:P ratios were highest in mature stand. It indicated that the growth rates were relatively faster in Young stand and Half-mature stand, resulting in Pinus massoniana needing large amounts of N and P in the two stands. (2) In early degradation period of litter, C contents increased but P contents decreased with the increasing stand densities, N contents were not different among four densities. C:P and N:P ratios were relatively higher in Middle-high and High density stands, resulting in Pinus massoniana needing large amounts of N and P and higher P reabsorption in these stands. (3) The C contents and C:N, C:P, and N:P ratios in latter degradation period of litter were lower than those in early degradation period of litter, but N and P contents were adverse. It indicated that N and P were enriched to litters along the advancing degradation periods. (4) The difference of C contents between the early and the latter degradation period of litter was relatively higher in Half-mature, Middle-high, and High density stands, but C:N and C:P ratios was relatively lower, indicating that the degradation rates of litters C were relatively higher in these stands. The above results suggested that Pinus massoniana may need large amounts of N and P in Half-mature, Middle-high, and High density stands, and resulting in high nutrient resorption efficiency; additionally, there were high potential degradation rates of litter carbon, which was beneficial to return litter C to soils in these forest stands.
