Most relevant applications of the zoology, botany, microbiology, and food analysis and traceability sciences to NHFG.
Diverse examples for each of these applications are shown in S1 Table and S2 Table (see also S1 Text) and described in the section applications of NHFG. NHFG, nonhuman forensic genetics.

Pipeline showing the main steps usually involved in processing forensic nonhuman DNA samples.
The exact procedure will depend on the conditions available at each laboratory. The process starts with the evaluation of the case and sample collection (green boxes). The procedure continues in the laboratory, where the DNA is extracted from the biological source material and analyzed according to an appropriate protocol (blue boxes). The genetic information is then compared with reference databases and the results are described in a written report (red boxes).
Fig 3.
Pipeline showing the evolutionary analysis of genetic data oriented to NHFG.
Data and tasks are shown in boxes, and databases and computer frameworks are shown in circles. Population genetic parameters include measures of genetic diversity, genetic differentiation, and demographics. The phylogenetic analysis requires the previous identification of recombination and can be performed ignoring or considering a substitution model of evolution. NHFG, nonhuman forensic genetics.
