Echinoidea Clypeasteroidea
Biodiversity Journal, 2014, 5 (2): 291–358 Analysis of some astriclypeids (Echinoidea Clypeast- eroida) Paolo Stara1* & Luigi Sanciu2 1Centro Studi di Storia Naturale del Mediterraneo - Museo di Storia Naturale Aquilegia, Via Italia 63, Pirri-Cagliari and Geomuseo Monte Arci, Masullas, Oristano, Sardinia, Italy; e-mail: [email protected] *Corresponding author The systematic position of some astriclypeid species assigned through times to the genera Amphiope L. Agassiz, 1840 and Echinodiscus Leske, 1778 is reviewed based on the plating ABSTRACT pattern characteristics of these two genera universally accepted, and on the results of new studies. A partial re-arrangement of the family Astriclypeidae Stefanini, 1912 is herein pro- posed, with the institution of Sculpsitechinus n. g. and Paraamphiope n. g., both of them char- acterized by a peculiar plating-structure of the interambulacrum 5 and of the ambulacra I and V. Some species previously attributed to Amphiope and Echinodiscus are transferred into these two new genera. Two new species of Astriclypeidae are established: Echinodiscus andamanensis n. sp. and Paraamphiope raimondii n. sp. Neotypes are proposed for Echin- odiscus tenuissimus L. Agassiz, 1840 and E. auritus Leske, 1778, since these species were still poorly defined, due to the loss of the holotypes and, for E. auritus, also to the unclear geographical/stratigraphical information about the type-locality. A number of additional nom- inal fossil and extant species of "Echinodiscus" needs revision based on the same method.

STAHEL Zoologiscbes Museum der Universitlit Zi~ricb; Ziirich, Scbweiz ABSTRACT: Environmental conditions affecting the occurrence of Astropecten aranciacus (Asteroidea, Echinodermata). In shallow water off the north coast of Sardinia (western Mediterranean) the frequency of occurrence of the starfish Astropecten aranciacus was recorded in 70 sample areas of 25 ms each. Four environmental factors, namely depth, average sand grain diameter, number of mollusc species, and number of individuals of the genus Echino- cardium proved to be related to the abundance of A. aranciacus. The sediment contained many species, each, as a rule, being present at low abundance. The molluscs found and their sizes are listed.

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. -

FINAL ENVIRONMENTAL ASSESSMENT WAIKIKI BEACH MAINTENANCE Honolulu, Hawaii May 2010 Prepared for: State of Hawaii Department of Land and Natural Resources P.O. Box 621 Honolulu, HI 96813 Prepared by: Sea Engineering, Inc. Makai Research Pier Waimanalo, HI 96795 SEI Job No. 25172 THIS PAGE INTENTIONALLY LEFT BLANK FINDING OF NO SIGNIFICANT IMPACT (FONSI) WAIKIKI BEACH MAINTENANCE, HONOLULU, HAWAII Description of the Proposed Action The project site is located on Waikiki Beach, along the shoreline of Mamala Bay on the south shore of Oahu, Hawaii. The shoreline proposed for beach maintenance extends approximately 1,700 linear feet from the west end of the Kuhio Beach crib walls to the existing groin between the Royal Hawaiian and Sheraton Waikiki hotels. Since 1985 the shoreline has been chronically eroding and receding at an average annual rate of 1.5 feet. The purpose of the project is to restore and enhance the recreational and aesthetic benefits provided by the beach, as well as maintaining lateral access along the shore. The proposed project will include the following primary components: The recovery of up to 24,000 cubic yards (cy) of sand from deposits located 1,500 to 3,000 feet offshore in a water depth of about 10 to 20 feet. Pumping the sand to an onshore dewatering site to be located in an enclosed basin within the east Kuhio Beach crib wall. Transport of the sand along the shore and placement to the design beach profile. The removal of two old deteriorated concrete sandbag groin structures located at the east end of the project area. -

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. -

Crab Predators Are More Important at Higher Latitudes

To understand large-scale variation in biotic interactions, we quantify consumption (predation and herbivory) along 2500 km of the Chilean coast (19°S–42°S). We deployed tethering assays at ten sites with three diferent baits: the crab Petrolisthes laevigatus as living prey for predators, dried squid as dead prey for predators/scavengers, and the kelp Lessonia spp. for herbivores. Underwater videos were used to characterize the consumer community and identify those species consuming baits. The species composition of consumers, frequency of occurrence, and maximum abundance (MaxN) of crustaceans and the blenniid fsh Scartichthys spp. varied across sites. Consumption of P. laevigatus and kelp did not vary with latitude, while squid baits were consumed more quickly at mid and high latitudes. This is likely explained by the increased occurrence of predatory crabs, which was positively correlated with consumption of squidpops after 2 h. -
The Echinoderm Fauna of Turkey with New Records from the Levantine Coast of Turkey
Proc. of middle East & North Africa Conf. For Future of Animal Wealth THE ECHINODERM FAUNA OF TURKEY WITH NEW RECORDS FROM THE LEVANTINE COAST OF TURKEY Elif Özgür1, Bayram Öztürk2 and F. Saadet Karakulak2 1Faculty of Fisheries, Akdeniz University, TR-07058 Antalya, Turkey 2İstanbul University, Faculty of Fisheries, Ordu Cad.No.200, 34470 Laleli- Istanbul, Turkey Corresponding author e-mail: [email protected] ABSTRACT The echinoderm fauna of Turkey consists of 80 species (two Crinoidea, 22 Asteroidea, 18 Ophiuroidea, 20 Echinoidea and 18 Holothuroidea). In this study, seven echinoderm species are reported for the first time from the Levantine coast of Turkey. These are, five ophiroid species; Amphipholis squamata, Amphiura chiajei, Amphiura filiformis, Ophiopsila aranea, and Ophiothrix quinquemaculata and two echinoid species; Echinocyamus pusillus and Stylocidaris affinis. Turkey is surrounded by four seas with different hydrographical characteristics and Turkish Straits System (Çanakkale Strait, Marmara Sea and İstanbul Strait) serve both as a biological corridor and barrier between the Aegean and Black Seas. The number of echinoderm species in the coasts of Turkey also varies due to the different biotic environments of these seas. There are 14 echinoderm species reported from the Black Sea, 19 species from the İstanbul Strait, 51 from the Marmara Sea, 71 from the Aegean Sea and 42 from the Levantine coasts of Turkey. Among these species, Asterias rubens, Ophiactis savignyi, Diadema setosum, and Synaptula reciprocans are alien species for the Turkish coasts.

Taiwans irregular sea urchin fauna now comprises 19 valid species in 11 families. New records include Fibularia ovulum Lamarck (Fibulariidae), Astriclypeus manni Verrill (Astriclypeidae), Linopneustes sp. (Palaeopneustidae), Schizaster lacunosus (Linnaeus) (Schizasteridae), Brissus latecarinatus (Leske), and Rhynobrissus pyramidalis A. Agassiz (Brissidae). Species accounts and figures of 14 species collected by the author are presented. Key words: Sea urchins, Irregular urchins, Echinoderms, Taiwan, Taxonomy. Sea urchins may be either regular or irregular. Regular urchins have an almost spherical symmetry. Irregular urchins display varying degrees of bilateral symmetry. They are common macrobenthic organ- isms along the coasts of Taiwan. However, only a few papers dealing with them have been published (Tokunaga 1900, Ohshima 1927, Hayasaka 1948, Peng and Tiao 1971, Chen and Chang 1981, Shigei 1981, Wang 1984) on the ecology and systematics of these animals from the waters of Taiwan. The regu- lar sea urchins from Taiwan have been revised by Chen and Chang (1981). However, there has been no study of the irregular urchins from Taiwan since Hayasaka (1948) except for a new species, Tai- wanaster mai (now Sinaechinocyamus mai), de- scribed by Wang (1984).
