Abstract: Phyllodial pores and the identification of two subspecies of sea urchins in Mexico: Meoma ventri- cosa grandis (Pacific) and Meoma ventricosa ventricosa (Atlantic). The genus Meoma inhabits Mexican waters and is represented by the subspecies Meoma ventricosa grandis in the Pacific and Meoma ventricosa ventricosa in the Atlantic. Both subespecies are morphologically similar. We studied the morphological differences between Meoma ventricosa grandis and Meoma ventricosa ventricosa, specifically in the patterns of phyllodial pore pairs and kind of sediments where they live. The number of pores differs among subspecies until M. ventricosa grandis reaches 110 mm of total lenght. The difference in the number of phyllodial pores can be an adaptation to the size of silt grain. Rev. Biol. Trop. 56 (Suppl. 3): 13-17. Epub 2009 January 05.

Dissodactylus crinitichelis is the only species of the genus reported in Brazil. The pea crab species has been already recorded associated with four species of echinoids in Brazilian waters. This paper reviews the known hosts for D. crinitichelis and registers for the first time the association between the pea crab and the sand dollar Leodia sexiesperforata increasing to five the number of known hosts for the crab. Key Words: Ecological association, ectosymbiont, Pinnotheridae.

Corrected 02-V-2017. Accepted 07-VI-2017. Abstract: Between 1978 and 1982 the ruins of the Templo Mayor of Tenochtitlan were exhumed a few meters northward from the central plaza (Zócalo) of Mexico City. The temple was the center of the Mexica’s ritual life and one of the most famous ceremonial buildings of its time (15th and 16th centuries). More than 200 offerings have been recovered in the temple and surrounding buildings. We identified vestiges of 14 species of echino- derms (mostly as disarticulated plates). These include six species of sea stars (Luidia superba, Astropecten regalis, Astropecten duplicatus, Phataria unifascialis, Nidorellia armata, Pentaceraster cumingi), one ophiu- roid species (Ophiothrix rudis), two species of sea urchins (Eucidaris thouarsii, Echinometra vanbrunti), four species of sand dollars (Mellita quinquiesperforata, Mellita notabilis, Encope laevis, Clypeaster speciosus) and one species of sea biscuit (Meoma ventricosa grandis). -

Priorities for Effective Management of Coral Diseases
Priorities for Effective Management of Coral Diseases Andrew W. Bruckner NOAA Fisheries Office of Protected Resources 1315 East West Highway Silver Spring, MD 20910 [email protected] SUMMARY Diseases of scleractinian corals and associated species have proliferated in recent years, and they are now recognized as important phenomena capable of altering the structure and composition of coral reefs. Since the early 1990s there has been a concerted effort to characterize coral diseases, including the application of novel molecular tools to confirm identities of pathogens and understand mechanisms of host response and resistence. Most of the causative agents of emerging diseases, factors contributing to their occurrence and spread, and consequences on coral populations remain incompletely understood, however. A long-term, multi-disciplinary research and monitoring program for coral diseases is necessary to assist resource managers in identifying and responding to emerging coral diseases. These efforts should involve management-driven strategies that include 1) an early warning system to predict and identify disease outbreaks; 2) documentation of spatial distribution and temporal variations of coral diseases and other syndromes at local to global scales; 3) elucidation of relationships of environmental stressors, localized anthropogenic impacts, and widespread phenomena such as global warming and El Niño on coral health, disease, degradation and recovery; 4) development of standardized terminology for diseases and other syndromes through -

Brachyura: Pinnotheridae)
BULLETIN OF MARINE SCIENCE. 32(2): 584-594, 1982 CORAL REEF PAPER ECHINODERM SPINE STRUCTURE, FEEDING AND HOST RELA TrONSHIPS OF FOUR SPECIES OF DISSODACTYLUS (BRACHYURA: PINNOTHERIDAE) Malcolm Telford ABSTRACT Stomach contents of four species of Dissodactylus living on different host echinoids were examined. Estimates were made of the relative degrees of host dependence of these crabs. Dissodactylus primitivus, collected on the spatangoid urchins, Meoma ventricosa and Plagiobrissus grandis, takes about 50 to 60% of its food from the hosts. Both D. crinitichelis and D. mellitae, symbiotic with the c1ypeastroids Mellita sexiesperforata and M. quin- quiesperforata respectively, obtain over 80% of their food from host tissues whilst D. cal- mani appears to feed exclusively on the tissues of its c1ypeasteroid host, Clypeaster rosa- ceus. Differences in behavior and feeding habits can be attributed partly to the structure of host spines, Allometric analysis and scanning electron microscopy indicate that the spines of C. rosaceus are less porous than those of the other species examined. The spines of Mellita are significantly more porous than others, and those of Plagiobrissus grandis are hollow. On host species with porous spines, considerable areas are denuded by the feeding activity of the crabs. Morphometry of crab chelae is clearly related to feeding activity. Dissodactylus calmani, with slender claws, has not been found with spines in the stomach whereas D. me/litae has relatively small but very robust chelae and was always found to include spines in its diet. Differences in feeding habits, morphometry and life cycles indicate that D. primitivus is truly primitive, D. calmani the most specialized, and that D. -

Abstract: This paper is primarily intended as a guide to researchers who wish to know what echinoid species are available in the Bay of Panama and in the Gulf of Chiriqui, how to recognize them, and what has been published about them up to 2004. Fifty seven species of echinoids have been reported in the literature as occurring in the Pacific waters of Panama, of which I have collected and examined 31, including two species, Caenopedina diomediae and Meoma frangibilis, that have hitherto only been mentioned in the literature from single type specimens. For the 31 species I was able to examine, I list the localities in which they were found, my impression as to their relative abundance, the characters that distinguish them, and what is known about their biology and evolution. -
