Gulf Of Nicoya

A checklist of the marine and estuarine fishes of the inner part of the Gulf of Nicoya, Pacific coast of Costa Rica, Central America, was compiled by examining a museum fish collection, resulting in 72 families and 274 species. Of these species, 127 (46.4%) were marine species and 147 (53.6%) were estuarine-associated species. In terms of their life history and considering the habitat type classification, 188 (almost 70% of the total) were categorized as species inhabiting soft-bottom habitats, reflecting the large estuarine environment and rich fish diversity of the Gulf despite its relatively small area in the tropical Eastern Pacific region. Furthermore, the list contains 13 threatened species of IUCN Red List, which need further research to understand their abundance and their exposure to habitat loss in the Gulf. Further detailed studies on its fish fauna and habitat are needed to better understand and conserve biodiversity within the whole Gulf.

The Family

The Panamic biogeographic province has long been thought to harbour a rich pyramidellid fauna. In the compilation of Keen (1971) the family is second only to the Turridae in being the most speciose gastropod family in the region, and no less than 350 species are listed. However a number of these have later been recognized to be synonyms, and in the update of the compilation by Skoglund (2002) the number of pyramidellids was reduced to 258.

A new canuellid, Microcanuella bisetosa gen. n., sp. n., was collected on the Pacific coast (Gulf of Nicoya) of Costa Rica. Though the male is still unknown, a new genus is established, mainly because of the reduced armature of P1, P4, and P5. The small-sized M. bisetosa sp. n. is a mesopsammic species, inhabiting the interstices of coarse sediments of a beach slope.

<p>Existe poca información disponible sobre los sitios de forrajeo de las poblaciones de tortugas marinas del Pacífico Oriental, lo cual dificulta el diseño de estrategias de conservación tanto en el ámbito nacional como internacional.  Realizamos observaciones en cinco sitios a lo largo del Pacífico Norte de Costa Rica (Cabo Blanco, Punta Coyote, Punta Pargos, Punta Argentina y Bahía Matapalito) entre el 2010-2013, utilizando redes de enmalle tortugueras con luz de malla de 45 cm, con el objetivo de explorar y documentar nuevos sitios de forrajeo.  Estandarizamos la Captura Por Unidad de Esfuerzo (CPUE) como tortugas capturada por 100m de relinga superior por hora de inmersión, el cual varió de 0.06 en Punta Pargos hasta 0.58 en Bahía Matapalito para tortugas carey (Eretmochelys imbricata), y de 0.01 en Punta Coyota hasta 0.10 en Cabo Blanco para tortugas verde del Pacífico (Chelonia mydas).  Encontramos rangos de tamaño específicos por sitio para E.imbricata en Bahía Matapalito y Cabo Blanco, con promedio ± Desviación Estándar (SD) del Largo Curvo de Caparazón (CCL) de 42.46 ± 17.66cm y 61.25±13.08cm respectivamente.  Tan solo se encontró un individuo en los demás sitios con CCL de 49.6cm hasta 60.5 cm.  Se capturaron tortugas verde en tres de los sitios observados, con CCL de 67.67±19.44cm en Cabo Blanco, 69.40±9.40cm en Punta Coyote. y un único individuo en Bahía Matapalito con un CCL de 56.2cm. La ausencia de clases de tamaño de adultos para E.imbricata, así como de clases de tamaño de juveniles para la tortuga verde del Pacífico, enfatiza la complejidad de la distribución específica por especies durante las distintas fases de vida de las tortugas marinas en el Pacífico Oriental, y la necesidad emergente de implementar monitoreos a largo plazo en diferentes sitios a lo largo del Pacífico Norte del país para comprender la conectividad entre hábitats. El presente estudio revela la existencia de sitios de forrajeo frágiles desprotegidos para la tortuga carey y verde en el Pacífico norte de Costa Rica, y sirve de guía para futuras iniciativas de investigación para fortalecer estrategias de conservación en el ámbito nacional e internacional.</p>

319 marine mollusk species collected yet on Gorgona Island (Pacific coast of Colombia, Panamic zoogeographic province) by various persons and scientific expeditions are listed. 209 species (65.5%) inhabit the whole province (México to Ecuador or Perú), 21 species (6.6%) are known from the southern part (Central America to Ecuador or Perú) and 4 species (1.3%) have their presently known northern limit in Gorgona and spread south to Ecuador or Peru. 42 species (13.2%) have their presently known southern distribution limit in Gorgona, 14 other species (4.4%) reaching in Gorgona their southernmost point on the continental shelf of South America are also known from Galapagos. 3 species (1.0%) have been collected on the continental shelf only in Gorgona and partly in Costa Rica. The distribution of the remaining 25 species (7-9%) is still not sufficiently known. 119 species from Gorgona have not yet been found on the mainland coast of Colombia. 8 species are amphipacific. The zoogeographic importance of Gorgona Island is based in the fact that the island is the southernmost point on the continental shelf with extensive coraline biotopes within the Panamic-Pacific faunal province.

The Pacific coast of Colombia has been poorly explored, and its fauna is one of the least known in the tropical eastern Pacific. Although knowledge of the decapod fauna from this coast has recently increased, the information is scattered in numerous sources. A review of the literature showed that 378 decapods have been reported from this coast, including the islands of Gorgona and Malpelo. The numbers of species are distributed as follows; Dendrobranchiata, 18; Caridea,79; Thalassinidea, 13; Palinura, 6; Anomura, 61; and Brachyura, 201 .Twenty-seven species are known exclusively from the Colombian coast, three of which are endemic to the islands of Malpelo or Gorgona. A list of nominal species is presented, including information on distribution, important references, and synonyms under which the taxa have been reported for this coast. A summary of the history of explorations of the Pacific coast of Colombia as it relates to decapods, is presented. Zoogeographic affinities are briefly discussed for the marine species based on published distributions. Affinities are greatest with the Gulf of California (51.8%), followed by the Galápagos (28.6%), the Indo-Pacific (8.8%), and the Caribbean- Atlantic (7.7%).

Introduction: The Gulf of Nicoya is the most important estuary on the Pacific coast of Costa Rica. Information on the presence of soft corals is scattered in the literature and in museum collections. Objective: To provide a list of soft corals reported for the estuary. Methods: We compiled the literature (2002-2020) and of the specimens deposited at the Museum of Zoology, University of Costa Rica. Results: Thirty species have been reported for the estuary (Clavulariidae, Gorgoniidae and Plexauridae). Most were collected on the eastern coast of the Nicoya Peninsula, and several species were described based on estuary specimens. Conclusion: The 30 species represent 79 % of those reported for Costa Rica. Despite this relatively high percentage, the sampling effort has been modest and other sites within the estuary should be explored.
