For centuries, naturalists from the Global North have traveled southwards to collect specimens of species from regions where there were many. The legacy of this is that the large natural history collections and the biodiverse regions of the world are often distant from one another. The unique and often disappearing species and ecosystems in these regions need conservation, yet much of the data on this biodiversity resides in collections and with the experts that work in them, rather than in the countries where it is needed. In this poster we zoom in on Grand Cayman, a small island in the Caribbean, facing severe threats to its endemic biodiversity - from habitat loss to introduced species. More specifically we focus on the endemic blue iguana ( Cyclura lewisi ) and the invasive green iguana ( Iguana iguana ). Specimens from the Cayman Islands are dispersed over American and European natural history collections and give data on the species present, their abundances and the interactions among those species (e.g. their food plants and parasites). Such data can be used in risk assessments and conservation planning, and the specimens themselves can inform research, such as population genetics. While the Cayman Islands are small they provide an excellent case study of the issues of conservation, society, climate and other environmental change in the tropics. Islands are highly sensitive to environmental change, but the lessons learned from them can be extended to other areas, including continents. On this poster, we describe the From Blue Iguanas to Blue Vervain project (Fig. 1), which aims to connect the biodiverse Caribbean UK Overseas Territories of Montserrat and the Cayman Islands with natural science collections around the world. We aim to learn ways to address issues of access and benefit-sharing, particularly how residents of these biodiverse places can benefit from the data and research linked to specimens originating in their islands.

This research examines biodiversity specimens from two areas of the Caribbean to understand patterns of collection and the roles of the people involved. Using open data from the Global Biodiversity Information Facility (GBIF) and Wikidata, we aimed to uncover geographic and historical trends in specimen use. This study aims to provide concrete evidence to guide collaboration between collection-holding institutions and the communities that need their resources most. We analysed biodiversity specimens from Montserrat and the Cayman Islands in three steps. First, we extracted specimen data from GBIF, disambiguated collector names, and linked them to unique biographical entries. Next, we connected collectors to their publications and specimens. Finally, we analysed the modern use of these specimens through citation data, mapping author affiliations and research themes. Specimens are predominantly housed in the Global North and were initially used by their collectors, whose focus was largely on taxonomy and biogeography. With digitisation, use of these collections remains concentrated in the Global North and covers a broader range of subjects, although Brazil and China stand out as significant users of digital collection data compared to other similar countries. The availability of open digital data from collections in the Global North has led to a substantial increase in the reuse of these data across biodiversity science. Nonetheless, most research using these data is still conducted in the Global North. For the non-monetary benefits of digitisation to extend to the countries of origin, capacity building in the Global South is crucial, Open Data alone are insufficient.Competing Interest StatementThe authors have declared no competing interest.Footnotes* http://doi.org/10.5281/zenodo.13902532* http://doi.org/10.5281/zenodo.14056058* https://doi.org/10.5281/zenodo.13825234* https://doi.org/10.5281/zenodo.13823446

Sir: It is all too symptomatic of the lack of awareness in UK of its Overseas Territories and its responsibilities to them that you publish (\"Hurricane twice size of Charley to hit US\", 3 September) a satellite image of the hugely powerful Hurricane Frances centred over UK territory (the Turks and Caicos Islands) with some 20,000...
