Galapagos Genetic Code (Barcode)

The Galapagos Genetic Code (Barcode) project was created through collaboration between the Galapagos Science Center (GSC), the Universidad San Francisco de Quito (USFQ), the University of Exeter in the UK, the Agency for Regulation and Control of Biosafety and Quarantine for Galapagos (ABG), and the Galapagos Conservation Trust (GCT). This project arose in response to the economic impact caused by the COVID-19 pandemic on the Galapagos Islands and employed 79 people linked to tourism who had lost their income. Additionally, recognizing that there is limited knowledge about all species that make up the biodiversity of the Galapagos, this project is important both for researchers seeking to learn more about ecosystem health and preservation, and for the local community seeking to conserve their territory. Project funding was made possible thanks to the support of the Research and Innovation Fund and the Newton Fund, both belonging to the Global Challenges Research Fund of the UK Government.

The Galapagos Barcode project aims to catalog the biodiversity of the Galapagos Islands using non-invasive sampling techniques, such as “Environmental DNA (eDNA)” with a focus on marine-coastal ecosystems, and laboratory techniques such as “Metabarcoding” that are capable of generating large amounts of information. This has been done in order to build a more equitable, sustainable, and resilient future in Galapagos, improving knowledge about natural biodiversity and promoting community participation.

The project consisted of several stages, including participant selection, training, equipment acquisition, data collection, information processing, and analysis of results. “Often, scientists are thought of as one group of people and locals as another group of people, who really have nothing in common. During the pandemic, this initiative found a point where community and science could come together and work together. Participants were also able to learn about science, and what different techniques are used, from species recognition to the use of technology in genetics labs,” said Andy Russell, Professor of Animal Behavior at the University of Exeter in the UK.

The process of selecting and training personnel for the Galapagos Barcode project involved selecting 79 people from among 446 applicants. The training was conducted virtually by professors from USFQ in Ecuador, the Charles Darwin Foundation and international researchers from the University of Exeter in the UK, the University of California at Berkeley, and the Monterey Bay Aquarium Research Institute.

From September 2020 to October 2022, the Galapagos Barcode project carried out 28 field trips in the Galapagos Marine Reserve, collecting 1,896 botanical, water, soil, and endemic and invasive species DNA samples, and sequencing 466 assays.

To carry out the project, three laboratories were equipped on three islands: the Galapagos Science Center on San Cristóbal Island, ABG facilities on Santa Cruz Island, and the Municipal GAD facilities on Isabela Island. Each laboratory had state-of-the-art sequencing technology for the analysis of genetic barcodes and the collection and research of species DNA.

Among the preliminary results, it was observed that the soil microbiomes of Isabela, Santa Cruz, and San Cristóbal islands are different from each other, as well as along the altitudinal gradient. Additionally, it was observed that the environmental DNA methodology is capable of detecting at least twice as many species as conventional monitoring mechanisms. Therefore, standardization of this methodology will be sought to apply in the monitoring of marine coastal zones. The results analysis is expected to be completed by June 2023.

In 2022, the Galapagos Science Center (GSC) and the broader UNC & USFQ Galapagos Initiative will celebrate its 10th Anniversary. We are proud to announce the World Summit on Island Sustainability scheduled to be held on June 26–30, 2022 at the Galapagos Science Center and the Community Convention Center on San Cristobal Island.

The content of the World Summit will be distributed globally through social media and results documented through papers published in a book written as part of the Galapagos Book Series by Springer Nature and edited by Steve Walsh (UNC) & Carlos Mena (USFQ) as well as Jill Stewart (UNC) and Juan Pablo Muñoz (GSC/USC). The book will be inclusive and accessible by the broader island community including scientists, managers, residents, tourists, and government and non-government organizations.

While the most obvious goal of organizing the World Summit on Island Sustainability is to celebrate the 10th Anniversary of the GSC and the UNC-USFQ Galapagos Initiative, other goals will be addressed through special opportunities created as part of our operational planning of the World Summit.

For instance, we seek to elevate and highlight the Galapagos in the island conservation discourse, seeking to interact with other island networks in more obvious and conspicuous ways to benefit the Galapagos Islands, the UNC-USFQ Galapagos Initiative, and the world. We will seize the opportunity to further develop the I2N2 – International Islands Network-of-Networks. Further, we wish to highlight and emphasize multiple visions of a sustainable future for the Galapagos Islands and we cannot do this alone. Therefore, engaging the Ecuadorian Ministry of Environment, the Ministry of Tourism, the Government Council of Galapagos, the Galapagos National Park, and local Galapagos authorities, including government and non-government organizations and local citizen groups, is imperative.

Borrowing from Hawaii’s and Guam’s Green Growth Program and the Global Island Partnership, we wish to examine existing global programs that emphasize island sustainability and their incorporation into life, policies, and circumstances in the Galapagos Islands. We will also seek to enhance our connections with the institutional members of our International Galapagos Science Consortium and expand the Consortium through the recruitment of other member institutions. We will also work to benefit islands and their local communities by working with citizen groups as well as important NGOs who seek to improve the natural conditions in the Galapagos and diminish the impact of the human dimension on the future of Galapagos’ ecosystems.

Lastly, we will use the World Summit to benefit UNC & USFQ and our constituencies through a strong and vibrant communication plan about the World Summit, creating corporate relationships as sponsors, identifying funding goals through donors, and benefiting our study abroad program for student engagement in the Galapagos Islands. We plan to develop and issue a Galapagos Sustainability Communique after the World Summit that includes the vision and insights of all its participants for a sustainable Galapagos with applicability to global island settings.

We are eager to hear your perspective and have you join us at the World Summit on Island Sustainability!
