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.","PeriodicalId":105419,"journal":{"name":"Restoration & Management Notes","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-01-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115372168","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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","PeriodicalId":105419,"journal":{"name":"Restoration & Management Notes","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134417424","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.","PeriodicalId":105419,"journal":{"name":"Restoration & Management Notes","volume":"8 Suppl 2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126762742","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

An example of the latter is a wetland mitigation plan that used white alder (Alnus rhombifolia) even though the species is not found in the area of the mitigation. Taking more time to analyze the feasibility of the mitigation at the conceptual stage would help to alleviate these situations. Third, problems occur when a conceptual mitigation plan is given to a landscape architect who lacks familiarity with the species in the revegetation plan or their ecological niches in the landscape. They inevitably produce construction documents (planting plans, irrigation plans, and specifications) that do not reflect the intent of the conceptual plan. This problem is then often confounded by revegetation designers who are unable to correct such mistakes because they cannot read landscape architecture documents. Yet, it is these documents, not the conceptual plans, that are used to install projects. The use of white aider at several wetland mitigation sites in the San Diego area are perfect examples. The plans call for planting this tree six to nine meters (20 to 30 feet) above the water table when it naturally occurs within 0.3 to 1.2 meters (1 to 4 feet) along the stream edge. Likewise, this species is often placed on landscape plans out of all proportion to its presence in natural populations simply because it is the only species the landscape architects are familiar with in the plant palette. To resolve this problem revegetation designers should know planting and irrigation plan symbolism well enough to review and approve all construction documents. In most cases they should either be in a position to produce the initial landscape planting plan or provide the landscape architect in the conceptual mitigation plan with typical habitat planting layouts using landscape architectural symbols. These layouts should show both mature spread of species and describe their ideal ecological locations. Finally, the revegetation designer must be able to modify standard landscape specification packages to suit revegetation project requirements° Fourth, the revegetation designer must be enough of a nurseryman to know what native plants are available and which ones will do well under the environmental regime created at the project site. Plans should not specify a multitude of species not currently in production without making adequate provision for their collection or production. Contract growing should be required to alleviate problems of obtaining plants and revegetation designers should oversee plant production. Designers should aiso severely limit substitutions in the specifications, as such latitude usually leads to an oversimplification of the plant paiette. Designers should write specifications in order to procure or grow important but difficult to obtain species. 236","PeriodicalId":105419,"journal":{"name":"Restoration & Management Notes","volume":"74 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-07-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114803704","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
