Wildlife Forensics and Genetic Conservation

Wildlife forensics integrates molecular genetics with legal frameworks to detect, trace and deter illegal exploitation of fauna. By applying tools originally developed for human crime investigation—such as DNA profiling, microsatellite analysis and single nucleotide polymorphism (SNP) typing—investigators can identify species, individual animals and geographic origins of seized specimens. These insights enable law enforcement to dismantle trafficking networks and inform targeted protection measures. In parallel, genetic conservation uses population‐level data to monitor genetic diversity, inbreeding and connectivity among remnant populations. Together, these approaches strengthen biodiversity protection by guiding reintroduction programmes, optimising breeding designs and verifying the provenance of biological materials in trade. Advances in non‐invasive sampling, high‐throughput sequencing and portable field platforms are driving a more responsive interface between conservation genetics and wildlife crime scene investigation, with global relevance for threatened species management and policy enforcement.

Research from Nature Portfolio

Recent studies have built and applied multilocus genotype reference databases for trafficked wildlife. In one case study, researchers assembled a comprehensive microsatellite database for a neotropical primate, sampling across all major habitats to create a genotype reference database (GRDB). Bayesian assignment methods correctly reassigned most individuals to their true origin clusters and geographic localities. When applied to confiscated and reintroduced animals, the approach revealed illegal capture hotspots and exposed mismatches between release sites and natural origin, thereby demonstrating how genetic assignment can guide more effective reintroduction strategies and enforce wildlife protection laws.

Technical terms

Forensic genetics: Application of genetic analysis to legal investigations of wildlife crime.

Conservation genetics: Study of genetic variation to guide management and recovery of endangered species.

Microsatellite markers: Short tandem repeats in the genome used to distinguish individuals and populations.

Single nucleotide polymorphism (SNP): A one‐base variation in DNA sequence that serves as a high‐resolution marker for genetic differentiation.

Genotype reference database (GRDB): A curated repository of genetic profiles from known populations, used to assign unknown samples to their geographic origin.
