Open science in tropical biodiversity holds immense potential for advancing research, conservation, and sustainable development in these ecologically rich regions. By making research findings, data, and methodologies freely accessible to the global community, open science fosters collaboration, accelerates scientific discovery, and enhances transparency in biodiversity studies. In the tropics, where biodiversity hotspots face numerous threats such as habitat loss, climate change, and species extinction, open science offers opportunities to generate comprehensive datasets, monitor ecosystem health, and develop evidence-based conservation strategies. Moreover, open science principles promote inclusivity by enabling broader participation from diverse stakeholders, including local communities, indigenous peoples, and citizen scientists, in biodiversity research and monitoring efforts. By harnessing the power of open science, we can unlock the full potential of tropical biodiversity conservation and ensure the sustainable management of these invaluable ecosystems for future generations.
