Study Notes
Species Identification
- Involves identifying species from remains, products, or parts found in wildlife crime scenes
- Methods used:
- Morphological analysis (e.g., shape, size, color)
- Microscopic analysis (e.g., hair, feathers, scales)
- Chemical analysis (e.g., proteins, lipids)
- Molecular analysis (e.g., DNA, PCR)
- Importance: accurate species identification is crucial in wildlife forensic investigations to determine the origin and legality of seized items
DNA Analysis
- Used to identify species, determine ancestry, and link evidence to specific individuals
- Techniques used:
- PCR (Polymerase Chain Reaction) for DNA amplification
- DNA sequencing for species identification
- DNA profiling for individual identification
- Mitochondrial DNA analysis for species identification
- Applications:
- Identifying species from trace evidence (e.g., hair, saliva)
- Linking evidence to specific individuals (e.g., poached animals)
- Determining the origin of seized items (e.g., ivory, rhino horn)
Wildlife Crime Scene Investigation
- Involves collecting, processing, and analyzing evidence from wildlife crime scenes
- Steps involved:
- Securing the crime scene
- Documenting the scene (e.g., photographs, videos)
- Collecting evidence (e.g., physical, biological, trace)
- Processing and analyzing evidence
- Importance: thorough crime scene investigation is crucial in gathering evidence and reconstructing the crime
Poaching Investigation
- Involves investigating the illegal killing, capture, or trade of wildlife
- Methods used:
- Physical evidence collection (e.g., carcasses, traps, weapons)
- Interviewing witnesses and suspects
- Analyzing financial and trade records
- Using undercover operations and sting operations
- Importance: investigating poaching crimes is essential in disrupting illegal wildlife trade networks and bringing perpetrators to justice
Trace Evidence
- Involves analyzing small, often overlooked evidence found at wildlife crime scenes
- Types of trace evidence:
- Hair, feathers, scales, and other biological materials
- Fibers, textiles, and other man-made materials
- Paint, glass, and other substances
- Soil, pollen, and other environmental materials
- Importance: trace evidence can provide crucial links between suspects, victims, and crime scenes in wildlife forensic investigations
Species Identification
- Identifies species from remains, products, or parts found in wildlife crime scenes
- Involves morphological analysis, examining shape, size, and color
- Microscopic analysis examines hair, feathers, and scales
- Chemical analysis examines proteins and lipids
- Molecular analysis examines DNA and uses PCR
DNA Analysis
- Identifies species, determines ancestry, and links evidence to specific individuals
- PCR amplifies DNA for analysis
- DNA sequencing identifies species
- DNA profiling identifies individuals
- Mitochondrial DNA analysis identifies species
- Applications include identifying species from trace evidence, linking evidence to individuals, and determining the origin of seized items
Wildlife Crime Scene Investigation
- Collects, processes, and analyzes evidence from wildlife crime scenes
- Secures the crime scene to prevent contamination
- Documents the scene with photographs and videos
- Collects physical, biological, and trace evidence
- Processes and analyzes evidence to reconstruct the crime
Poaching Investigation
- Investigates the illegal killing, capture, or trade of wildlife
- Collects physical evidence, such as carcasses, traps, and weapons
- Interviews witnesses and suspects
- Analyzes financial and trade records
- Uses undercover operations and sting operations to disrupt illegal trade networks
Trace Evidence
- Analyzes small, often overlooked evidence found at wildlife crime scenes
- Includes biological materials, such as hair, feathers, and scales
- Includes man-made materials, such as fibers, textiles, and paint
- Includes environmental materials, such as soil and pollen
- Provides crucial links between suspects, victims, and crime scenes
