Mapping the geographic origin of captive and confiscated Hermann's tortoises: a genetic toolkit for conservation and forensic analyses
<p>The illegal trade has been threatening tortoise populations worldwide for decades. Nowadays, however, DNA typing and forensic genetic approaches allow us to investigate the geographic origin of confiscated animals and to relocate them into the wild, providing that suitable molecular tools and reference data are available. Here we assess the suitability of a small panel of microsatellite markers to investigate patterns of illegal translocations and to assist forensic genetic applications in the endangered Mediterranean land tortoise <em>Testudo hermanni hermanni</em>. Specific allelic ladders were created for each locus and tested on several reference samples. We used the microsatellite panel to (i) increase our understanding of the population genetic structure in wild populations with new data from previously unsampled geographic areas (overall 461 wild individuals from 28 sampling sites); (ii) detect the presence of non-native individuals in wild populations; and (iii) identify the most likely geographic area of origin of 458 confiscated individuals hosted in Italian seizure and recovery centers. Our analysis initially identified six major genetic clusters corresponding to different geographic macro-areas along the Mediterranean range. Long-distance migrants among wild populations, due to translocations, were found and removed from the reference database. Assignment tests allowed us to allocate approximately 70% of confiscated individuals of unknown origin to one of the six Mediterranean macro-areas. Most of the assigned tortoises belonged to the genetic cluster corresponding to the area where the respective captivity center was located. However, we also found evidence of long-distance origins of confiscated individuals, especially in centers along the Adriatic coast and facing the Balkan regions, a well-known source of illegally traded individuals. Our results clearly show that the microsatellite panel and the reference dataset can play a beneficial role in reintroduction and repatriation projects when confiscated individuals need to be re-assigned to their respective macro-area of origin before release, and can assist future forensic genetic applications in detecting the illegal trade and possession of <em>Testudo hermanni</em> individuals.</p>
A case of forensic genomics in Uganda reveals animal ownership and low exotic genetic introgression in indigenous cattle
<p class="MsoNormal"><span>The cattle industry contributes to Uganda's agricultural output. It however faces challenges that include theft and parentage ascertainment. These challenges can benefit from recent developments in genomics and bioinformatics technologies. In the current study, we provided a proof-of-concept conflict resolution method based on the available bovine genomic tools. Briefly, two farmers we refer to as A and B contested for ownership of a group of 9 cattle. To offer objective and data-based guidance to resolving this conflict, we sampled hair samples of the 9 contested cattle as well as 7 and 2 cattle from farmers A and B respectively that were identified by these farmers as the closest relatives of the contested animals. DNA was extracted from each of the collected hair samples and subsequently genotyped on the Illumina BovineSNP50-24 version 3 BeadChip for 53218 DNA Single Nucleotide Polymorphisms (SNP) variants. Upon genotype data cleaning we retained ~30,000 SNPs which were used for different genomic analyses including principal component analysis, identity by state (IBS) analysis, and hierarchical clustering analysis, to establish the genetic relationships within and between the investigated animal groups.</span></p>

Data from: Broad-scale genetic diversity of Cannabis for forensic applications
Cannabis (hemp and marijuana) is an iconic yet controversial crop. On the one hand, it represents a growing market for pharmaceutical and agricultural sectors. On the other hand, plants synthesizing the psychoactive THC produce the most widespread illicit drug in the world. Yet, the difficulty to reliably distinguish between Cannabis varieties based on morphological or biochemical criteria impedes the development of promising industrial programs and hinders the fight against narcotrafficking. Genetics offers an appropriate alternative to characterize drug vs. non-drug Cannabis. However, forensic applications require rapid and affordable genotyping of informative and reliable molecular markers for which a broad-scale reference database, representing both intra- and inter-variety variation, is available. Here we provide such a resource for Cannabis, by genotyping 13 microsatellite loci (STRs) in 1 324 samples selected specifically for fibre (24 hemp varieties) and drug (15 marijuana varieties) production. We showed that these loci are sufficient to capture most of the genome-wide diversity patterns recently revealed by NGS data. We recovered strong genetic structure between marijuana and hemp and demonstrated that anonymous samples can be confidently assigned to either plant types. Fibres appear genetically homogeneous whereas drugs show low (often clonal) diversity within varieties, but very high genetic differentiation between them, likely resulting from breeding practices. Based on an additional test dataset including samples from 41 local police seizures, we showed that the genetic signature of marijuana cultivars could be used to trace crime scene evidence. To date, our study provides the most comprehensive genetic resource for Cannabis forensics worldwide.
