Mapping Important Shark and Ray Areas (ISRAs) in the Central and South American Pacific: Existing knowledge and data needs

Publications

Chondrichthyans, a class of aquatic vertebrates (sharks, rays, and chimaeras), are facing a global extinction crisis driven by overfishing, habitat degradation, climate change, and pollution. Of the approximately 1,250 species studied, more than one third (37%) are at risk of extinction according to the International Union for Conservation of Nature Red List, making this group the second most threatened among vertebrates. There is limited biological and ecological information available on chondrichthyans, which hinders the identification of critical habitats. As a response, the Important Shark and Ray Areas (ISRA) approach was developed a tool designed to map essential areas for the life cycle processes of these species.

Mapeo de Áreas Importantes para Tiburones y Rayas (ISRAs) en el Pacífico Central y Sudamericano: Conocimientos existentes y necesidades de datos

Publicaciones

Los condrictios, una clase de vertebrados acuáticos (tiburones, rayas y quimeras), enfrentan una crisis global de extinción provocada por la sobrepesca, la degradación del hábitat, el cambio climático y la contaminación. De las aproximadamente 1.250 especies estudiadas, más de un tercio (37%) está en peligro de extinción según la Lista Roja de la Unión Internacional para la Conservación de la Naturaleza, lo que convierte a este grupo en el segundo más amenazado entre los vertebrados. La información biológica y ecológica de los condrictios es escasa, lo que limita la identificación de hábitats críticos. Como resultado de ello, se desarrolló el enfoque de las Áreas Importantes para Tiburones y Rayas (ISRA, por sus siglas en inglés), una herramienta diseñada para mapear zonas esenciales para los procesos del ciclo de vida de estas especies.

Assessment of feeding patterns of the mottled scorpionfish (Pontinus clemensi) in the Galápagos Marine Reserve

Publications

The Spotted Scorpionfish (Pontinus clemensi) is a species of high economic, ecological, and cultural value in the Galápagos Islands. In recent years, it has gained relevance in the artisanal fisheries of the Galápagos Marine Reserve (GMR) due to the overexploitation of traditional species such as bacalao (Mycteroperca olfax) and camotillo (Paralabrax albomaculatus). As a result, its presence in local markets and its consumption within the community have increased. Additionally, it is one of the main prey items in the diet of the Galápagos sea lion (Zalophus wollebaeki), underscoring its importance in ecosystem dynamics. However, there is limited information about its trophic ecology. Understanding its diet is essential for evaluating its ecological role and for developing sustainable fishery management strategies.

Evaluación de los patrones alimentarios del pez escorpión moteado (Pontinus clemensi) en la Reserva Marina de Galápagos.

Publicaciones

El pez escorpión moteado (Pontinus clemensi), conocido localmente como “brujo”, es una especie de alto valor económico, ecológico y cultural en las Islas Galápagos. En los últimos años, ha ganado relevancia en la pesca artesanal de la Reserva Marina de Galápagos (RMG), debido a la sobreexplotación de especies tradicionales como el bacalao y el camotillo. Como resultado, su presencia en los mercados locales y su consumo dentro de la comunidad registran un aumento. Además, es una de las principales presas dentro de la dieta del lobo marino, lo que resalta su importancia en la dinámica del ecosistema. Sin embargo, la información sobre su ecología trófica es escasa. Comprender su dieta es fundamental para evaluar su rol ecológico y establecer medidas de manejo pesquero sostenibles.

Exploring stress and morphology in two songbird species across urban, agricultural, and natural habitats on San Cristóbal Island, Galápagos

Publications

This study analyzed how land use changes affect two bird species in the Galápagos: the small ground finch (Geospiza fuliginosa) and the yellow warbler (Setophaga petechia aureola). The goal was to understand whether habitat alterations, caused by urbanization and agriculture on human-populated islands, affect their size, weight, and levels of the hormone corticosterone, which is linked to stress.

Changes in marine iguana (Amblyrhynchus cristatus) heart rates suggest reduced metabolism during El Niño events

Publications

The marine iguanas of Galápagos (Amblyrhynchus cristatus) have the ability to lower their heart rate to conserve energy—an adaptation developed to cope with El Niño events. During these periods, warmer ocean temperatures reduce algae, their main food source, threatening the survival of the world’s only marine lizard.

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!
