| description |
A list of 54 copepod species (Crustacea) in 23 families is presented for the Pacific coast of Costa Rica. Identifications are from zooplankton samples of the Victor Hensen Expedition during December 1993 and February 1994. Samples were taken with a Bongo net (0,60 m net opening. 2.50 m net length) with 200 μm mesh size. Oblique hauls were done from the surface to the ground at a towing speed of aprox. 1 knot. 37 species (68.5%) we re found in the Gulf of Nicoya. 36 in Golfo Dulce (66.6%) and 17 (31.4%) species were common to both gulfs. while only twelve species (22.2%) were found in Coronado Bay. Four species (7.4%) were distributed along the coast and were common to the three regions: Paracalanus parvus, Euchaeta sp., Oithona plumifera and O. similis. Eleven species of calanoids found normally in the Costa Rica Dome show the influence of typical oceanic waters principally at the mouth of Gulf of Nicoya. Differences were observed in the composition and presence of the copepod species when the inner and outer (upper and lower) pans of both gulfs were compared. Gulf of Nicoya was dominated in its upper pan by typical neritic estuarine species like Acartia lilljenborgii. Paracalanus parvus and Hemicyciclops thalassius as well as species of Pseudodiaplomus. On the other hand a more oceanic composition of copepods was observed in the lower part of the gulf. BOth small species, like Oncaea venusta, as well as larger species, such as Pleuromamma rubusta, Eucalanus attenustus, E. elongatus and Rhinalanus nasatus, were typical of these waters. Oithona plumifera and O. similis were found in the lower part too; and both species are typical from oceanic water. Coronado Bay was characterized by the presence of typical oceanic species like Neocalanus gracilis, Euchaeta longicornis, Eucalanus attenuatus and Haloptilus ornatus with more transitional species like Clausocalanus pergens and C. furcatus near the coast. In the Golfo Dulce differences in copepod composition were also observed, but the separation of the species was not so evident. Outer stations were represented by oceanic species like Paracalanus aculeatus, Pleuromamma gracilis, Lucicutia ovalis, Candancia catula, Euchaeta wolfendendeni and Oncaea mediterranea, while the inner station, located at the upper pan of the Gulf, was more characterized by a mixed copepod group. with both neritic species like Pseudodiaptomus wrighti, Acartia danae, A. clausi, Canthoralanus pauper as well as oceanic species like ScolicitricelIa marginata, Saphirina nicramaculata or Oncaea conifera. Two species of Coryceaus, C. flaccus and C. speciosus, were identifed in the outer stations of Golfo Dulce. while C. brehmi was found in inner stations of Gulf of Nicoya. The majority of copepods found are typical of the east Pacific. This paper constitutes an additional work about the copepods in the Gulf of Nicoya and the first report of copepod species for Coronado Bay and Golfo Dulce. |

La identificaci6n de las especies fue hecha de muestras de zooplancton de la Expedición Vfctor Hensen durante diciembre de 1993 y febrero de 1994 en colaboración con el Centro de Ecología Marina Tropical de la Universidad de Bremen, República Federal de Alemania. EI zooplancton fue muestreado con una red tipo Bongo (0.60 m de boca. 2.50 m de longitud) can 200 μm de poro. Se hizo arrastres oblicuos de algunos metros arriba del fonda hasta la superficie a una velocidad de arrastre de aproximadamente un nudo.37 especies (68.5%) fueron identificadas para el Golfo de Nicoya, 36 (66.6%) para el Golfo Dulce y 17 (31.4%) comunes a ambos golfos: 12 especies (22.2%) fueron identificadas para la Bahía de Coronado. Cuatro especies (7.4%) estuvieron distribuídas a largo de la costa y fueron comunes en las tres regiones: Paracalanus parvus, Euchaeta sp., Oithona plumifera y O. similis. Once especies de calanoideos, registrados en el Domo de Costa Rica, muestran la influencia de aguas típicamente oceánicas principalmente en la boca del golfo de Nicoya. Hubo diferencias en la composición y presencia de especies de copépodos cuando fueron comparadas las partes internas y externas de ambos golfos (parte superior y parte inferior). EI golfo de Nicoya estuvo dominado en su parte superior por especies de copepodos típicamente neríticas-estuarinas como Acartia lilljenborgii, Paracalanus parvus, Hemyciciops thalassius así como también por especies del género Pseudodiaptomus. Por otro lado especies mis oceánicas fueron observadas en la parte más baja del golfo. Tanto especies pequeñas como Oncaea venusta, como también especies más grandes como Pleuromamma robusta, Eucalanus attenuatus, E. elongatus y Rhincalanus nasutus fueron típicas de estas aguas. Oithona plumifera y O. similis fueron encontradas en la parte inferior del golfo y son típicas de aguas oceánicas. La región de la Bahía Coronado estuvo caracterizada por la presencia de especies oceánicas como Neocalanus gracilis, Euchaeta longicornis, Neocalanus attenuatus y Haloptilus ornatus con una copepofauna más transicional dominada por especies como Clausocaumus pergens y C. furcalus conforme se acercó a la costa. En el Golfo Dulce también hubo diferencias. pero la separación de las especies no fue tan evidente. Las estaciones externas estuvieron representadas por especies oceánicas como Paracalanus aculeatus, Pleuromamma gracilis, Lucicutia ovalis, Candacia catula, Eucaetta wolfendeni y Oncaea mediterranea. mientras que las estaciones intemas estuvieron más caracterizadas por una mezcla de especies tanto neríticas (Pseudodiaplomus wrigthi, Acartia danae, A. clausi, Canthocalanus pauper) como oceánicas (Scolicithricella marginata. Saphirina nicromaculala y Oncaea conifera). Dos especies de Coryceaus, C. flaccus y C. speciosus fueron identificadas de las estaciones externas del Golfo de Nicoya mientras que C. brehmi fue encontrada en estaciones internas del Golfo de Nicoya. Este artículo constituye un trabajo adicional acerca de los copepodos del Golfo de Nicoya y el primer reporte de especies de copépodos para la región de Barra Coroado y Golfo Dulce.Universidad de Costa Rica1996-12-01info:eu-repo/semantics/publishedVersionArticleartículo originalhttp://purl.org/coar/resource_type/c_2df8fbb1info:eu-repo/semantics/articleapplication/pdfhttps://revistas.ucr.ac.cr/index.php/rbt/article/view/29547Revista de Biología Tropical; Vol. 44 No. S3 (1996): Volume 44 – Supplement 3 – December 1996: Pacific Coastal Ecosystems of Costa Rica with emphasis on the Golfo Dulce and adjacent areas: a synoptic view based on the RV Victor Hensen expedition 1993/1994 and previous studies; 103–113Revista de Biología Tropical; Vol. 44 Núm.
