A method can include receiving a document associated with a checklist item. A method can include identifying a template associated with the document. A method can include identifying an area of the document associated with a value of a key-value pair based at least in part on the template. A method can include extracting, using a first optical character recognition process, the value from the area. A method may cause display of the value. A method can include receiving a corrected value from the user. A method may include extracting, using a second optical character recognition process, full text of the document. A method may include determining a location of the corrected value in the document. A method may include updating the first optical character recognition process, wherein updating the first optical character recognition process causes the first optical character recognition to extract the value from the location.

The invention belongs to the field of ecology, and particularly relates to a habitat transformation and regression method for promoting field population reconstruction of northern cypripedium plants, which comprises the following steps of: firstly, evaluating habitat suitability based on terrain, soil, vegetation and interference factors, and screening out places to be regressed; performing habitat transformation on the regression site from four dimensions of an arbor layer, a shrub layer, a herbaceous layer and soil; then cooperatively planting northern cypripedium plant seedlings and seed bags filled with northern cypripedium plant seeds to realize adult individual library establishment and natural update potential reserve; and finally, fixing, tracking and monitoring the regression population, and evaluating the regression effect. According to the method, the regression success rate of the northern cypripedium plants is increased from less than 30% to 60%, population self-maintenance is realized, the method is successfully applied in Liaoning Baichi national natural reserve, and scientific and northern technical support is provided for field population reconstruction of northern cypripedium species such as cypripedium macranthum.

The invention discloses an SNP (Single Nucleotide Polymorphism) marker combination for Yangtze alligator individual population tracing and application thereof, and belongs to the technical field of In order to solve the problem that a reliable, simple and low-cost Yangtze alligator population tracing method is lacked in the prior art, the invention provides an SNP marker combination for Yangtze alligator individual population tracing, and compared with a molecular biology molecular marker STR or SNP amplification method in the prior art, the SNP marker combination does not need to design and optimize amplification primers, and has the advantages of high specificity, high specificity, high specificity and high sensitivity. The experimental operation process involved in the traceability process is greatly simplified, the experimental complexity is reduced, and many other interference factors are eliminated. By screening high-quality SNP loci, a rapid, reliable and low-cost Chinese alligator individual population tracing method is established, and a new technical guarantee is provided for captive breeding genetic management and field population protection.
