In the realm of biological and ecological studies, accurate species identification is paramount. Traditional methods often rely on morphological characteristics, which can be subjective and challenging, especially when dealing with cryptic species, juvenile stages, or degraded samples. Our company offers cutting-edge species identification services using molecular markers, providing a reliable and precise approach to unraveling the complexities of biodiversity.

et al., 2022)
Technical Principles
Molecular markers are specific segments of DNA or RNA that exhibit variations among different species. These variations can be detected through sophisticated laboratory techniques, enabling the identification and differentiation of even closely related organisms. The process typically involves the following steps:
- DNA Extraction: High-quality DNA is extracted from the provided biological samples, such as tissue, blood, hair, feathers, or environmental DNA (eDNA).
- PCR Amplification: Specific DNA regions containing molecular markers are amplified using the polymerase chain reaction (PCR) technique.
- Sequencing: The amplified DNA fragments are subjected to DNA sequencing to determine the precise order of nucleotides (A, T, C, G).
- Analysis and Comparison: The obtained sequences are analyzed and compared against extensive reference databases or other known sequences to identify the species.
Technical Features
- Accuracy: Molecular markers offer unparalleled accuracy in species identification, surpassing traditional methods, especially for challenging specimens.
- Versatility: This technique can be applied to a wide range of organisms, including animals, plants, fungi, and microorganisms.
- Objectivity: Molecular identification relies on objective genetic data, eliminating subjectivity associated with morphological identification.
- Sensitivity: Even trace amounts of DNA can be used for identification, enabling analysis of degraded or processed samples.
Applications
- Biodiversity Assessments: Comprehensive surveys of species diversity in various ecosystems, including terrestrial, aquatic, and marine environments.
- Conservation Biology: Monitoring endangered and threatened species, detecting invasive species, and informing conservation management strategies.
- Ecological Studies: Investigating species interactions, food webs, and ecosystem dynamics.
- Evolutionary Biology: Reconstructing phylogenetic relationships, studying speciation events, and understanding evolutionary processes.
- Forensic Science: Identifying species from trace evidence in criminal investigations, wildlife forensics, and food authenticity testing.
- Agriculture: Characterizing plant varieties, detecting pathogens, and managing pests.
- Fisheries Management: Identifying fish stocks, assessing population connectivity, and combating illegal fishing.
Environmental Benefits
- Non-invasive Sampling: In many cases, DNA can be obtained from non-invasive samples like hair, feathers, or eDNA, minimizing disturbance to organisms and their habitats.
- Early Detection of Invasive Species: Rapid and accurate identification of invasive species enables timely intervention and mitigation efforts, protecting ecosystems from harmful impacts.
- Conservation of Endangered Species: Monitoring populations of endangered species through genetic analysis aids in conservation planning and management.
- Sustainable Resource Management: Accurate species identification supports sustainable fisheries and forestry practices by ensuring proper stock assessment and preventing overexploitation.
