“…In essence, the similarities in analog and ortholog variable components of genomes provide forensic investigation of nonhuman biological substances in the same manner as for human forensics, but distinctions existing in different organisms and species, i.e., genomic architectures, reproductive strategies and genetic diversity, are continuously broadening the dependent scientific areas. The benefits stemming from the extension of forensic genetics toward nonhuman relations were clearly recognized decades ago [225], and the incorporated application of animal, plant or microorganisms has been actualized in a large scale of caseworks, from animal attacks [226,227] to bioterrorism [228], as well as in wildlife crimes [229,230], identification of food composition [231,232], Cannabis sp. chemotyping [233,234], and even the estimation of postmortem interval and skin microbiomes [235,236].…”

The importance of biological traces and evidences related to a criminal matter has been recognized for a long time. The examination of the expression of genetic polymorphism has been an integral part of the multidisciplinary field of medico-legal autopsy for over a century. Since the initial application of blood group antigens for personalization of a putative perpetrator in a murder case, the discipline of forensic genetics has evolved as a standard of forensic sciences. The real breakthrough, the application of molecular tools and processes for the in-vitro replication of genetic substances, has increasingly allowed the exploitation of advances of molecular genetics for both forensic and criminal investigations. Although there are certainly many more applications and scientific fields in the medico-legal arena, the relatively fast progress of genetics, which has accelerated recently with state-of-art technologies, can provide ever more relevant information in relation to a corpse or the cause and manner that resulted in the corpse for autopsy. This topic concerns the currently accepted forensic DNA technology, and the last section reviews commonly used markers for nuclear and mitochondrial DNA analysis as well as ongoing research. This review also focuses on the increasingly important non-human sources of DNA, and shortly covers the main aspects of animal forensic DNA examination.

“…Although genetic differentiation within species was not higher than with microsatellites, the move towards the use of SNPs for traceability is underway, as shown by the use of Blanc-Jolivet et. al.·Silvae Genetica (2015) [182][183][184][185][186][187][188][189][190][191][192][193] DOI:10.1515/sg-2015-0017 edited by Thünen Institute of Forest Genetics this marker type in several animal species (BEKKEVOLD et al, 2015;NEGRINI et al, 2008;OGDEN and LINACRE, 2015), and even in human (O'DUSHLAINE et al, 2010). Screening of large amount of loci, followed by selection of loci showing high genetic differentiation and/or outliers (BEKKEVOLD et al, 2015;GLOVER et al, 2010;OGDEN and LINACRE, 2015) might be a good strategy to develop cost-effective marker sets for genetic traceability.…”

“…Although many studies pro- vided results on genetic assignment, only a subset used this two-step procedure (DEGEN et al, 2013;FRANTZ et al, 2006;HONJO et al, 2008;HOWARD et al, 2009;JOLIVET and DEGEN, 2012;MAUDET et al, 2002;NEGRINI et al, 2008), which provides high security in forensic applications, as the true origin might have not been sampled (MANEL et al, 2002). Other methods for exclusion testing include calculation of likelihood ratios (BEKKEVOLD et al, 2015;OGDEN and LINACRE, 2015). In other words, assignment methods associated with exclusion probabilities estimation can address the question -can the material originate from a given stand?…”

“…As shown by GUICHOUX et al (2013), discrimination among Q. robur and Q. petraea was higher at 262 SNPs selected for high interspecific differentiation than at 12 SSRs. Efficient marker detection and screening methods will allow the setup of SNPs sets containing a strong geographical signal (OGDEN and LINACRE, 2015). Another advantage of SNP over SSR data is the straightforward standardization among laboratories and genotyping methods, which should make possible the development of large-scale datasets for reference stands.…”

Traceability of forest material has received recently increasing interest and European regulations already apply on forest reproductive material and timber. DNA fingerprinting methods allow identification of species and control of geographic origin, providing that genetic reference data is available. In this review, we focus on the two economically important European oak species, Quercus robur and Q. petraea. We describe the available molecular markers and data, and discuss their applicability for traceability systems of forest reproductive material at a European scale. We also provide insights on the use of DNA fingerprinting on timber material.

“…Hunting, as it is done nowadays, is not sustainable because forest areas become smaller, and the number of animals is also reduced [16]. This leads to extinction of different animal species and loss of biodiversity [17]. Although DNA analyses today are very accurate, molecular forensics of wildlife is still complex because there are no standardized laboratory protocols for species identifi cation [13].…”

The main reasons for wildlife forensic research are animal poaching, illegal trade, and falsifi ed game meat products. Small trace amounts, old and degraded materials present the most common samples in revealing criminal activities in this fi eld. This is the reason why it is crucial to use adequate and reliable methods and samples to identify animal species killed outside the hunting season or species protected by law. In this study, different endpoint PCR and real-time PCR protocols were compared in the identifi cation of three Cervidae species (Capreolus capreolus, Cervus elaphus, Dama dama) from old and damaged material found in an enclosed area where the animals were kept. From a total of 129 samples, end point PCR provided results for 119 samples, while real-time PCR was successful in all cases. Also, we created and tested a protocol for simultaneous analyses of different types of samples, which is of great importance as when the amplifi cation is carried out simultaneously it is more cost effi cient and speeds up the process.
