“…Alvarado & Cortés (2009), reported it as M. stokessi from the Gulf of Nicoya, and the Museum of Zoology of the University of Costa Rica has specimens (MZUCR-420), collected from this estuary. It has been reported as Encope (Mellitella) stokesii from El Salvador (Pacific, Gulf of Fonseca), by Barraza & Hasbún (2005).…”

“…More recently it has been reported from offshore waters of the Gulf of California and from coastal waters of Sinaloa (Mexico) by Solís-Marín et al (2005). Alvarado & Cortés (2009) the sampling period. Dexter (1977) also found that M. stokesii migrates towards the sediment surface during low tide, when the sediment is list of marine echinoderms of Costa Rica, and the Museum of Zoology of the University of Costa Rica has specimens from the Gulf of Nicoya (MZUCR-421).…”

“…The availability of long term data sets for tropical echinoderms is rare in the literature, and published reports deal maily with the description of benthic population patterns over the annual cycle, as in M. stokesii from Panama (Dexter 1977), or on the abundance of planktonic larvae over longer periods, as in Williams & García-Sais (2010). A total of 229 species of echinoderms have been reported from Costa Rica, with the Echinoidea (55 species) and the Ophiuroidea (69), as the more diverse groups (Alvarado & Cortés 2009) but little information is available on the ecology of species from intertidal sedimentary habitats. Thus, the objective of this note is to make accesible data on, M. stokesii and A. geminata found on a tidal flat in Gulf of Nicoya estuary.…”

Information on changes over time in the biodiversity and ecology of tropical systems is of increasing importance against the background of local, regional, and global dynamics. This study aimed to contribute with long-term data on the abundance fluctuations of two species of echinoderms from a tropical tidal flat. From February 1984 to December 1986, March 1985 to April 1987, and July 1994 to September 1996, core samples (17.7cm 2 , 15cm deep) were collected at low tide at a mud-sand flat in the mid upper Gulf of Nicoya estuary, Costa Rica, as part of a survey of the benthic community. Among more than 100 taxa, the burrowing brittle star, Amphipholis geminata, and the sand dollar, Mellitella stokesii, consistently appeared in the samples over the study period. A total of 63 M. stokesii and 149 A. geminata were collected. The 43 sand dollars found during 1984-1985, give an approximate density of 35 ind./m 2 , which is within the range reported for this species. M. stokesii was almost absent from 1994 to 1996, while A. geminata had its peak of abundance at the end of 1995. Low abundances of the sand dollar during the rainy seasons (May-November) and slight increments in dry seasons (December-April) cores, also agrees with a report from the region. A. geminata also presented an irregular pattern of abundance, with slight increases at the end of the rainy seasons or during the dry seasons, when higher salinities are more suitable for echinoderms. The patchy spatial distribution of both species makes difficult the detection of patterns with a corer. Nevertheless, this information is unique due to its extensive time coverage and provides a baseline for future surveys designed specifically for the study of tropical intertidal estuarine echinoderms.

“…These localities are all located in the Indian Ocean and Red Sea regions. Only once has this species been reported from a locality outside the Indo-Pacific: Cocos Island, in the Tropical Eastern Pacific (TEP; Lessios et al 1996, Alvarado andCortés, 2009). These authors argue that the warm phase of El Niño Southern Oscillation could favor the dispersal and settlement of this species, and considering this recent discovery, we believe this could be a plausible explanation for its occurrence at Gorgona Island.…”

“…The genus Cassidulus is an ancient group with species recorded since the upper Eocene while having a circumtropical distribution restricted to shallow waters (Mortensen, 1948;Kier, 1962). The irregular sea urchin Cassidulus caribaearum has been reported in Belize, the US Virgin Islands (excluding St Croix), San Marteen, Panama (Kier, 1975;Gladfelter, 1978), the Mexican and the Costa Rican Caribbean (Bravo-Tzompantzi et al, 1999;Laguarda-Figueras et al, 2005;Alvarado et al, 2008;Alvarado & Cortés, 2009). The species is encountered at depths ranging from 0.5 to 197 m and it aggregates at densities up to 100 ind./m 2 while burying in coarse sand (Gladfelter, 1978;Bravo-Tzompantzi et al, 1999).…”

Journal of the Marine Biological Association and was launched in April 2009. It is a response to the growing interest in research on the identification of marine organisms in locations where they have not formerly been found, as well as the effects of human activities on the ecology and distribution of marine and estuarine species. The new online journal evolved from the JMBA2 Marine Biodiversity Records online resource which was published from 2005 on the MBA website (www.mba.ac.uk/jmba/jmba2biodiversityrecords.php) as a free peer-reviewed resource to collate these valuable records for the marine community. Lists of the papers published online were printed in the end of year issues of the Journal of the Marine Biological Association as a guide to readers. The new formal journal includes original research articles and commissioned reviews of changes in geographical range of species, the effects of the introduction of novel species to ecosystems, the effects of pollution on established ecosystems, policy and implementation of conservation issues, effects of other human activities, including aquaculture, biodiversity
