Bridging genetic knowledge gaps in a biodiversity hotspot through conservation training

The Mesoamerican biodiversity hotspot is extraordinarily rich, yet most invertebrate genetic diversity remains invisible, hampering effective conservation planning amid accelerating biodiversity loss. How can this hidden diversity be revealed while simultaneously building local scientific capacity? Panama BioResearch, a hands-on molecular course, addressed this issue by embedding DNA barcoding within training and conservation contexts. Participants collected terrestrial and marine invertebrates across three protected areas and generated 158 DNA barcode sequences, two-thirds of which represented first genetic records for their species. Comparisons with public databases revealed striking under-representation of Mesoamerican taxa, especially non-iconic groups with key ecosystem roles. Barcoding also enabled the rapid detection of two invasive species, prompting immediate management responses. Beyond documenting biodiversity, this experience demonstrates that small, low-cost educational initiatives can produce actionable data, foster local expertise, and inform conservation priorities. Embedding molecular tools in education provides a scalable model for linking research, training, and management in species-rich but data-deficient regions.
