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. Not surprisingly, most available information concerns abundant shallow water species, while little is known about deep water, rare, or infaunal species. Rev. Biol. Trop. 53(Suppl. 3): 147-170.

Aceptado 04-XI-2014. Abstract: Taxonomy and ecologic biogeography of the irregular Echinoids (Echinoidea: Irregularia) from Mexico. Mexico owns 643 species of echinoderms, almost 10% of the known echinoderm species in the planet. Its geographic location -between the oceanic influences of the Western Central Atlantic and the Eastern Central Pacific- largely explains its enormous biological and ecological diversity. Research on echinoderms in Mexico began in the late nineteenth century; however, there are no reviews on its irregular echinoids. This work reviews the taxonomic and geographic information of irregular echinoids from Mexico, housed in four collections: 1) Colección Nacional de Equinodermos “Ma.

  • Diets and Coexistence of the Sea Urchins Lytechinus Variegatus and Arbacia Punctulata (Echinodermata) Along the Central Florida Gulf Coast
    MARINE ECOLOGY PROGRESS SERIES Vol. 295: 171–182, 2005 Published June 23 Mar Ecol Prog Ser Diets and coexistence of the sea urchins Lytechinus variegatus and Arbacia punctulata (Echinodermata) along the central Florida gulf coast Janessa Cobb, John M. Lawrence* Department of Biology, University of South Florida, Tampa, Florida 33620, USA ABSTRACT: The basis for coexistence of similar species is fundamental in community ecology. One mechanism for coexistence is differentiation of diets. Lytechinus variegatus and Arbacia punctulata coexist in different microhabitats along the Florida gulf coast. Their great difference in morphology might affect their choice of microhabitats and diet. We analyzed diets of both species at 1 offshore and 1 nearshore site where both occurred in relatively equal numbers, an offshore site dominated by A. punctulata and an offshore site dominated by L. variegatus. Gut contents were analyzed to deter- mine the diet. A. punctulata prim. consumed sessile invertebrates except on dates when algal avail- ability was higher than normal. L. variegatus primarily consumed macroflora except on dates when macroflora was extremely limited. Electivity indices revealed no strong preferences for particular species of algae, although L. variegatus consumed many drift species. A. punctulata and L. variega- tus both fed in a random manner, although they avoided particular species of algae known to contain high concentrations of secondary metabolites. The diet of A. punctulata was correlated with algae only over rubble outcroppings at the offshore site with the highest biomass. Diets of offshore popula- tions were more similar to each other, regardless of the presence of conspecifics, than to those of populations at Caspersen Beach (nearshore site).

E-mails: [email protected], [email protected] 2Corresponding author Abstract Diadema setosum (Leske, 1778), a widespread tropical echinoid and key herbivore in shallow water environments is cur- rently expanding in the Mediterranean Sea. It was introduced by unknown means and first observed in southern Turkey in 2006. From there it spread eastwards to Lebanon (2009) and westwards to the Aegean Sea (2014). Since late 2016 spo- radic sightings of black, long-spined sea urchins were reported by recreational divers from rock reefs off the Israeli coast. Numerous attempts to verify these records failed; neither did the BioBlitz Israel task force encounter any D. setosum in their campaigns. Finally, a single adult specimen was observed on June 17, 2017 in a deep rock crevice at 3.5 m depth at Gordon Beach, Tel Aviv. Although the specimen could not be recovered, spine fragments sampled were enough to genet- ically verify the visual underwater identification based on morphology. Sequences of COI, ATP8-Lysine, and the mito- chondrial Control Region of the Israel specimen are identical to those of the specimen collected in 2006 in Turkey, unambiguously assigning the specimen to D.

    Hopkins and Smith, SI Appendix SI Appendix for Hopkins, Melanie J, and Smith, Andrew B. Dynamic evolutionary change in post-Paleozoic echinoids and the importance of scale when interpreting changes in rates of evolution. Corrections to character matrix Before running any analyses, we corrected a few errors in the published character matrix of Kroh and Smith (1). Specifically, we removed the three duplicate records of Oligopygus, Haimea, and Conoclypus, and removed characters C51 and C59, which had been excluded from the phylogenetic analysis but mistakenly remain in the matrix that was published in Appendix 2 of (1). We also excluded Anisocidaris, Paurocidaris, Pseudocidaris, Glyphopneustes, Enichaster, and Tiarechinus from the character matrix because these taxa were excluded from the strict consensus tree (1). This left 164 taxa and 303 characters for calculations of rates of evolution and for the principal coordinates analysis. Other tree scaling methods The most basic method for scaling a tree using first appearances of taxa is to make each internal node the age of its oldest descendent ("stand") (2), but this often results in many zero-length branches which are both theoretically questionable and in some cases methodologically problematic (3). Several methods exist for modifying zero-length branches. In the case of the results shown in Figure 1, we assigned a positive length to each zero-length branch by having it share time equally with a preceding, non-zero-length branch (“equal”) (4). However, we compared the results from this method of scaling to several other methods. First, we compared this with rates estimated from trees scaled such that zero-length branches share time proportionally to the amount of character change along the branches (“prop”) (5), a variation which gave almost identical results as the method used for the “equal” method (Fig.

    www.nature.com/scientificreports OPEN Phylogeography, colouration, and cryptic speciation across the Indo‑Pacifc in the sea urchin genus Echinothrix Simon E. Coppard1,2*, Holly Jessop1 & Harilaos A. Lessios1 The sea urchins Echinothrix calamaris and Echinothrix diadema have sympatric distributions throughout the Indo‑Pacifc. Diverse colour variation is reported in both species. To reconstruct the phylogeny of the genus and assess gene fow across the Indo‑Pacifc we sequenced mitochondrial 16S rDNA, ATPase‑6, and ATPase‑8, and nuclear 28S rDNA and the Calpain‑7 intron. Our analyses revealed that E. diadema formed a single trans‑Indo‑Pacifc clade, but E. calamaris contained three discrete clades. One clade was endemic to the Red Sea and the Gulf of Oman. A second clade occurred from Malaysia in the West to Moorea in the East. A third clade of E. calamaris was distributed across the entire Indo‑Pacifc biogeographic region. A fossil calibrated phylogeny revealed that the ancestor of E. diadema diverged from the ancestor of E. calamaris ~ 16.8 million years ago (Ma), and that the ancestor of the trans‑Indo‑Pacifc clade and Red Sea and Gulf of Oman clade split from the western and central Pacifc clade ~ 9.8 Ma. Time since divergence and genetic distances suggested species level diferentiation among clades of E. calamaris. Colour variation was extensive in E. calamaris, but not clade or locality specifc. There was little colour polymorphism in E. diadema. Interpreting phylogeographic patterns of marine species and understanding levels of connectivity among popula- tions across the World’s oceans is of increasing importance for informed conservation decisions 1–3.
