The cassiduloid echinoid Calilampas californiensis n. gen. and sp. is described from middle lower Eocene (“Capay Stage”) shallow-marine sandstones in both the middle part of the Bateque Formation, Baja California Sur, Mexico, and the lower part of the Llajas Formation, southern California. The new genus is tentatively placed in family Pliolampadidae. The cassiduloid Cassidulus ellipticus Kew, 1920, previously known only from the “Capay Stage” in California, is also present in “Capay Stage” shallow-marine sandstones of the Bateque Formation.

In order to determine if eastern Pacific green turtles (Chelonia mydas) exhibit feeding preferences samples of recently ingested food items were compared to the food resources available in the marine environment where C. mydas congregates. Stomach samples were collected by conducting gastric lavage and, at the same time, vegetation transects were conducted during spring and winter. Green turtles in our study selectively consumed seaweeds, with Codium amplivesiculatum and Gracialaria textorii as preferred species. Differences in the consumption of species were found across the two mentioned seasons and were consistent with changes in the availability of different algae species in the environment. Based on these results, it is recommended that sea turtle conservation plans along the Baja California Peninsula include Pacific coastal mangrove channels with a high diversity of algae species as priority areas for protection.

Two species of terebratulide brachiopods are described from the upper part of the Bateque Formation (middle Eocene) on the Pacific coast of Baja California Sur, Mexico, Terebratulina cf. Terebratulina louisianae Stenzel, 1940, and Terebratalia batequia n. sp. Terebratalia batequia n. sp. is the earliest confirmed record of the genus Terebratalia Beecher, 1893, which has been an important component of Pacific brachiopod faunas through to the present day. The occurrence of Terebratulina cf. Terebratulina louisianae Stenzel is one of the earliest records of the genus from the west coast of North America. These brachiopods, like other elements of the Bateque invertebrate fauna, may record Eocene migration from the Atlantic to Pacific Ocean via the Central American seaway.

The coastal lagoon system Bahía Magdalena / Almejas (BM/A) at the Pacific coast of Baja California Sur, México, is a large water body extremely important for ecological, economic and social reasons. Because of its natural environment BM/A was declared as one of the areas deserving marine conservation priority. The exact number of fishermen and their families living around the Bay is not known, and neither is the currently registered small boats in service, nor the fishing efforts, expenses and yields. Recently, several civil organizations started working in the BM/A with the mission to solve some of the identified environmental and social problems. However, because of the lack of reliable data, wide spread corruption, and undirected and uncoordinated research make it very difficult to suggest ways to improve the livelihood of the small-scale shrimp fishermen without endangering the environment. Some promising options are small-scale aquaculture projects, mainly for off-shore mollusks production, and to offer eco-tourist activities as well as eco-friendly sport fishing. Both bring local employment opportunities while maintaining a quality environment. En busca de sustentabilidad de la pesquería de camarón a baja escala en el sistema lagunar Magdalena-Almejas Baja California Sur, México: una revisión El sistema lagunar Bahía Magdalena / Almejas (BM/A) ubicado en la costa oeste de Baja California Sur, México, es un cuerpo de agua de extrema importancia bajo las perspectivas ecológica, económica y social. Dado su ambiente natural, BM/A es considerada un área prioritaria en términos de conservación marina. Se desconoce cuántas familias de pescadores viven entorno a la bahía, así como el número registrado de embarcaciones pequeñas en activo, el esfuerzo pesquero, sus gastos, o su rendimiento. Recientemente, varias organizaciones civiles comenzaron labores en BM/A bajo la consigna de resolver algunos de los problemas ambientales y sociales identificados. Sin embargo, debido a la falta de datos confiables y a la corrupción, aunados a investigación mal dirigida y sin coordinación, dificultan la posibilidad de sugerir maneras de mejorar la sustentabilidad de la pesca menor de camarón sin poner en riesgo el ambiente. Algunas alternativas prometedoras son los proyectos acuaculturales a pequeña escala, principalmente para producción de moluscos lejos de la costa, así como las actividades ecoturísticas y la pesca deportiva ecológicamente amigable, dado que ambas abren oportunidades de empleo locales conservando la calidad del ambiente.
