| description |
The nesting colony of green sea turtles (Chelonia mydas) at Guanahacabibes Peninsula Biosphere Reserve and National Park is one of the largest in the Cuban archipelago; however, little information about its nesting ecology is available. Temporal and spatial variation in nesting and reproductive success as well as morphometric characteristics of gravid females were used to ecologically characterize this colony. Nine beaches of the Southernmost coast of Guanahacabibes Peninsula were monitored for 14 years (1998-2012) to determine green turtle nesting activity, from May to September (peak nesting season in this area). Beach dimensions were measured to determine nest density using the length and the area. Afterward the beaches were divided in two categories, index and secondary. Females were measured and tagged to compare new tagged females (823) with returning tagged females (140). Remigration interval was also determined. Temporal variation was identified as the annual number of nesting emergences and oviposits per female, with apparent peaks in reproductive activity on a biennial cycle in the first six years followed by periods of annual increase in nest number (2003-2008) and periods of decreasing number of nests (2010-2012). We also found intra-seasonal variation with the highest nesting activity in July, particularly in the second half of the month. The peak emergence time was 22:00-02:00hr. In terms of spatial variation, smaller beaches had the highest nest density and nesting was more frequent 6-9m from the high tide line, where hatchling production was maximized although hatchling success was high on average, above 80%. Morphometric analysis of females was made and newly tagged turtles were smaller on average than remigrants. Our results are only a first attempt at characterizing Guanahacabibes’ populations but have great value for establishing conservation priorities within the context of national management plans, and for efficient monitoring and protection of nesting beaches. |

Por ello utilizamos la variación espacial y temporal de la anidación así como el éxito reproductivo y las características morfométricas de las hembras grávidas para realizar la primera caracterización ecológica de esta colonia. Se estudiaron nueve playas durante 14 años (1998-2012) desde mayo hasta septiembre (pico de anidación). Estas se dividieron en dos categorías: índices y secundarias. Las hembras fueron medidas y marcadas para comparar las nuevas hembras marcadas (823) con las remigrantes (140). Se detectó una variación temporal en la anidación a tres niveles: interanual, dentro de la temporada y durante la noche. Se observa un ciclo bienal en los primeros seis años, luego un incremento anual (2003-2008) seguido por un período de decrecimiento en las anidaciones (2010-2012). Dentro de la temporada se encontró un pico en el mes de julio aunque cambia de la primera quincena a la segunda en años diferentes y la hora de emergencia preferentemente de 22:00-02:00hr. En la variación espacial, las playas pequeñas tuvieron mayor densidad de anidación, especialmente entre los 6-9m hasta la línea media de marea alta, donde se maximiza la producción de neonatos, aunque el éxito de emergencia de los neonatos se mantuvo como promedio por encima del 80% en toda la playa. Morfométricamente las hembras remigrantes resultaron mayores como promedio que las marcadas por primera vez. Estos resultados son una primera aproximación para la caracterización de la colonia de Guanahacabibes pero tienen gran valor para establecer prioridades de conservación dentro del contexto de los planes de manejo nacionales así como para garantizar un monitoreo eficiente y la protección de las playas de anidación.Universidad de Costa Rica2013-12-01info:eu-repo/semantics/publishedVersionartículo originalhttp://purl.org/coar/resource_type/c_2df8fbb1info:eu-repo/semantics/articleapplication/pdfhttps://revistas.ucr.ac.cr/index.php/rbt/article/view/1286910.15517/rbt.v61i4.12869Revista de Biología Tropical; Vol. 61 No. 4 (2013): Volume 61 – Regular number 4 – December 2013; 1935–1945Revista de Biología Tropical; Vol. 61 Núm. 4 (2013): Volumen 61 – Número regular 4 – Diciembre 2013; 1935–1945Revista Biología Tropical; Vol. 61 N.º 4 (2013): Volumen 61 – Número regular 4 – Diciembre 2013; 1935–19452215-20750034-774410.15517/rbt.v61i4reponame:Portal de Revistas UCRinstname:Universidad de Costa Ricainstacron:UCRenghttps://revistas.ucr.ac.cr/index.php/rbt/article/view/12869/12126Derechos de autor 2013 Revista de Biología Tropicalacceso abiertohttp://purl.org/coar/access_right/c_abf2info:eu-repo/semantics/openAccess2022-10-13T15:04:37Zoai:portal.ucr.ac.cr:article/12869Portal de revistashttps://revistas.ucr.ac.cr/Universidadhttp://www.ucr.ac.crhttps://revistas.ucr.ac.cr/index.php/index/oaijorge.polanco@ucr.ac.crCosta RicaNo aplicaNo aplicaNo aplicaopendoar:2025-08-13T10:15:51.206Portal de Revistas UCR - Universidad de Costa Ricafalse |
