“…Apparently vagrant H. clarionensis are occasionally seen at Clipperton Atoll. Indeed, they were observed in the early 1990s Robertson, 1994, 1997), but neither earlier (Baldwin, 1963) nor later (Robertson, personal communication, Béarez and Seret, 2009;Fourriére et al, 2014). This suggest that rare dispersal does occur between the Revillagigedos and Clipperton, consistent with a long pelagic larval duration (approximately 25 days, Thresher and Brothers, 1985), thus providing a mechanism for the origin of H. limbaughi, as was suggested in general terms (Robertson, 2001).…”

a b s t r a c tIn this study we estimated the timing of speciation events in a group of angelfishes using 1186 RADseq markers corresponding to 94,880 base pairs. The genus Holacanthus comprises seven species, including two clades of Panama trans-Isthmian geminates, which diverged approximately 3-3.5 Mya. These clades diversified within the Tropical Eastern Pacific (TEP, three species) and Tropical Western Atlantic (TWA, two species) which our data suggest to have occurred within the past 1.5 My in both ocean basins, but may have proceeded via different mechanisms. In the TEP, speciation is likely to have followed a peripatric pathway, while in the TWA, sister species are currently partially sympatric, thus raising the possibility of sympatric speciation. This study highlights the use of RADseq markers for estimating both divergence times and modes of speciation at a 1-3 My timescale.

“…1), occurring mainly in the surge zone of clear seaward reefs (Lieske & Myers 1994). This specie was reported for the first time in the ETP at Clipperton Atoll, the only known location for this species in the ETP (Bearez & Séret, 2009;Fourriére et al, 2014). The present report details the first record of A. guttatus in Isla del Coco, a new location of this species in the ETP, and the easternmost extension of the species.…”

Background: Acanthurus guttatus is distributed from the Maldives to the Hawaiian Archipelago and the Pitcairn Islands, and as north as Ryukyu Islands and as south as New Caledonia. The only known locality in the Eastern Tropical Pacific is Clipperton Atoll where three vagrant specimens have been observed. Methods: On June 2016 and April 2017 small groups of A. guttatus were observed and photographed during SCUBA diving and snorkeling surveys for touristic suitability at Isla del Coco National Park, Costa Rica. Results: Six specimens of A. guttatus were observed swimming over shallow rocky reefs at Isla del Coco, a volcanic island located in the Eastern Tropical Pacific. Conclusions: This study represents the first record of A. guttatus at Isla del Coco, the second known location of occurrence in the Eastern Tropical Pacific, and the easternmost known range for the Whitespotted surgeonfish.

Marine biodiversity baseline for Área de Conservación Guanacaste, Costa Rica: published records

The diversity of tropical marine organisms has not been studied as intensively as the terrestrial biota worldwide. Additionally, marine biodiversity research in the tropics lags behind other regions. The 43,000 ha Sector Marino of Área de Conservación Guanacaste ( ACG , Marine Sector of Guanacaste Conservation Area), on the North Pacific coast of Costa Rica is no exception. For more than four decades, the terrestrial flora and fauna has been studied continuously. The ACG marine biodiversity was studied in the 1930’s by expeditions that passed through the area, but not much until the 1990’s, except for the marine turtles. In the mid 1990’s the Center for Research in Marine Science and Limnology ( CIMAR ) of the Universidad de Costa Rica ( UCR ) initiated the exploration of the marine environments and organisms of ACG . In 2015, ACG , in collaboration with CIMAR , started the BioMar project whose goal is to inventory the species of the marine sector of ACG (BioMar ACG project). As a baseline, here I have compiled the published records of marine ACG species, and found that 594 marine species have been reported, representing 15.5% of the known species of the Pacific coast of Costa Rica. The most diverse groups were the crustaceans, mollusks and cnidarians comprising 71.7% of the ACG species. Some taxa, such as mangroves and fish parasites are well represented in ACG when compared to the rest of the Costa Rican coast but others appear to be greatly underrepresented, for example, red algae, polychaetes, copepods, equinoderms, and marine fishes and birds, which could be due to sampling bias. Thirty species have been originally described with specimens from ACG , and 89 species are not known from other localities on the Pacific coast of Costa Rica except ACG . Most of the sampling has been concentrated in a few localities in Sector Marino, Playa Blanca and Islas Murciélago, and in the nearby waters of Bahía Santa Elena. In an effort to fill this gap, CIMAR is collaborating with ACG and a private foundation to start an inventory of the marine organisms of the conservation area. The project will be assisted by two marine parataxonomists, and all samples will be catalogued, photographed, bar coded and voucher specimens deposited at the Museo de Zoología, UCR . All the information will be available through Internet. It is anticipated that the BioMar project will fill many of the knowledge gaps and significantly more marine species will be encountered. This project could become a viable model for marine biodiversity inventories in other Costa Rican Conservation Areas (Áreas de Conservación) and in other countries.
