High genetic diversity and limited genetic connectivity in 2 populations of an endemic and endangered coral species: Porites sverdrupi

The coral Porites sverdrupi is the only scleractinian endemic to the Gulf of California. Over the last 2 decades its populations have been restricted to 3 areas, La Paz Bay, Loreto Bay, and Concepción Bay. As this species faces a high risk of extinction, there is an urgent need for biological, ecolo...

Over the last 2 decades its populations have been restricted to 3 areas, La Paz Bay, Loreto Bay, and Concepción Bay. As this species faces a high risk of extinction, there is an urgent need for biological, ecological, and genetic information for the guidance of conservation efforts. This is the first study on genetic diversity and connectivity in the species. For this, we analyzed coral colonies from Loreto Bay and Concepción Bay. Our results show that there is high genetic diversity in P. sverdrupi at both sites, with significant genetic structure between them. This condition is caused by a combination of short pelagic larval duration, low dispersal potential between the populations, and local adaptation. Our results emphasize the need for more research in order to establish adequate conservation strategies.  El coral Porites sverdrupi es el único coral escleractinio endémico del golfo de California. En las últimas 2 décadas sus poblaciones se han restringido a 3 áreas, bahía de La Paz, bahía de Loreto y bahía Concepción. Debido a que esta especie enfrenta un elevado riesgo de extinción, existe una urgente necesidad de generar información biológica, ecológica y genética que guíe los esfuerzos de conservación de la especie. Este es el primer trabajo sobre la diversidad y la conectividad genética en la especie, para lo cual analizamos las colonias coralinas de bahía de Loreto y bahía Concepción. Nuestros resultados muestran alta diversidad genética en ambas poblaciones de P. sverdrupi, con una estructura genética significativa entre ellas. Esta condición es causada por el tiempo de duración larval corto, el potencial de dispersión bajo entre las poblaciones y la adaptación local. Nuestros resultados enfatizan la necesidad de realizar más investigación para establecer estrategias adecuadas de conservación. 2018-03-22 2021-06-03T03:55:37Z 2021-06-03T03:55:37Z info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Peer-reviewed Article Artículo Arbitrado https://www.cienciasmarinas.com.mx/index.php/cmarinas/article/view/2790 10.7773/cm.v44i1.2790 https://hdl.handle.net/20.500.12930/7536 eng https://www.cienciasmarinas.com.mx/index.php/cmarinas/article/view/2790/420420427 Copyright (c) 2018 Ciencias Marinas application/pdf Iniversidad Autónoma de Baja California Ciencias Marinas; Vol. 44 No. 1 (2018); 49-58 Ciencias Marinas; Vol. 44 Núm. 1 (2018); 49-58 2395-9053 0185-3880
