Respuestas divergentes de la estructura del tamaño del cuerpo de los peces pelágicos y bentónicos a la lejanía y la protección de los humanos

Estructura del tamaño del cuerpo de los peces


La variación del tamaño corporal de los animales influye en múltiples procesos en los ecosistemas marinos, pero la heterogeneidad del hábitat ha impedido una evaluación exhaustiva del tamaño en los sistemas pelágicos (aguas medias) y bentónicos (fondo marino) a lo largo de gradientes antrópicos. En este trabajo, derivamos indicadores del tamaño de los peces a partir de 17,411 implementaciones de video estéreo con cebo para probar las diferencias entre las respuestas pelágicas y bentónicas a la lejanía de las presiones humanas y la efectividad de las áreas marinas protegidas (AMP). A partir de registros de 823.849 peces individuales, informamos respuestas divergentes entre sistemas, con una estructura de tamaño pelágico más profundamente erosionada cerca de los mercados humanos que la estructura de tamaño bentónica, lo que significa una mayor vulnerabilidad de los sistemas pelágicos a la presión humana. Se puede lograr una protección efectiva de la estructura de tamaño del bentónico mediante AMP ubicadas cerca de los mercados, contribuyendo así a la restauración del hábitat bentónico y la recuperación de los peces asociados. Por el contrario, la recuperación de los peces más grandes y más amenazados del mundo en sistemas pelágicos requiere la creación de áreas altamente protegidas en lugares remotos, incluso en alta mar, donde los esfuerzos de protección van a la zaga.

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!
