Abstract:

DNA barcoding is a powerful diagnostic technique in which short DNA sequences are employed for species identification (Savolainen et al., 2005). This method relies on sequencing a standardized genomic region from the target organism and comparing it to reference sequences in established databases. Such rapid and accurate species identification plays a critical role in biodiversity assessment and large-scale ecological monitoring programs. Among molecular approaches, DNA arrays and DNA barcodes have received considerable attention for their efficiency and reliability (Hajibabaei et al., 2007). In this research, DNA barcoding was applied as a tool to quantify biodiversity within a defined microhabitat at Cold Spring Harbor Laboratory. Plant and insect samples, representing 12 distinct specimens, were collected from an area of approximately one square meter. Sampling was conducted using insect nets and crackers as bait to attract arthropods. To ensure DNA quality under time constraints, d
