44th ALBERT L. TESTER MEMORIAL SYMPOSIUM APRIL 10-13th, 2019 THE DEPARTMENT OF BIOLOGY UNIVERSITY OF HAWAIʻI AT MĀNOA HISTORY of the ALBERT TESTER MEMORIAL SYMPOSIUM The Albert L. Tester Memorial Symposium is held in honor of Professor Albert Tester who, at the time of his death in 1974, was Senior Professor of Zoology at the University of Hawaiʻi at Mānoa. The faculty and students of the Department of Zoology proposed an annual symposium of student research papers as a means of honoring, in a continuing and active way, Dr. Tester’s lively encouragement of student research in a broad range of fields within marine biology. Today the Tester Memorial Symposium welcomes research from any scientific field.

Ivanenko 6,9 Corals harbor complex and diverse microbial communities that strongly impact host ftness and resistance to diseases, but these microbes themselves can be infuenced by stresses, like those caused by the presence of macroscopic symbionts. In addition to directly infuencing the host, symbionts may transmit pathogenic microbial communities. We analyzed two coral gall-forming copepod systems by using 16S rRNA gene metagenomic sequencing: (1) the sea fan Gorgonia ventalina with copepods of the genus Sphaerippe from the Caribbean and (2) the scleractinian coral Stylophora pistillata with copepods of the genus Spaniomolgus from the Saudi Arabian part of the Red Sea. We show that bacterial communities in these two systems were substantially diferent with Actinobacteria, Alphaproteobacteria, and Betaproteobacteria more prevalent in samples from Gorgonia ventalina, and Gammaproteobacteria in Stylophora pistillata. In Stylophora pistillata, normal coral microbiomes were enriched with the common coral symbiont Endozoicomonas and some unclassifed bacteria, while copepod and gall-tissue microbiomes were highly enriched with the family ME2 (Oceanospirillales) or Rhodobacteraceae. In Gorgonia ventalina, no bacterial group had signifcantly diferent prevalence in the normal coral tissues, copepods, and injured tissues. The total microbiome composition of polyps injured by copepods was diferent.

The ecological success of Cnidaria is predicated on several fascinating organismal innovations including symbiosis, colonial body plans and elaborate life histories, however, understanding the origins and subsequent diversification of these traits remains difficult due to persistent uncertainty surrounding the evolutionary relationships within Cnidaria. While recent phylogenomic studies have advanced our knowledge of the cnidarian tree of life, no analysis to date has included genome scale data for each major cnidarian lineage. Results: Here we describe a well-supported hypothesis for cnidarian phylogeny based on phylogenomic analyses of new and existing genome scale data that includes representatives of all cnidarian classes.

Yet little is known about symbiotic copepods, abundant and numerous microscopic crustaceans inhabiting almost every living coral colony. In this thesis, I investigate the genetic diversity of different groups of copepods associated with reef-building corals in distinct parts of the Indo-Pacific; determine species boundaries; and reveal patterns of biogeography, endemism, and host-specificity in these symbiotic systems. A non-destructive method of DNA extraction allowed me to use an integrated approach to conduct a diversity assessment of different groups of copepods and to determine species boundaries using molecular and taxonomical methods. Overall, for this thesis, I processed and analyzed 1850 copepod specimens, representing 269 MOTUs collected from 125 colonies of 43 species of scleractinian corals from 11 locations in the Indo-Pacific.

While one-third of the world’s reef corals are known to face heightened extinction risk from global climate and local impacts, prospects for the coral fauna in the South China Sea region amidst these threats remain poorly understood.

Box 9517, 2300 RA Leiden, The Netherlands [email protected] Abstract Most marine palaemonid shrimp species live in symbiosis with invertebrates of various phyla. These as- sociations range from weak epibiosis to obligatory endosymbiosis and from restricted commensalism to semi-parasitism. On coral reefs, such symbiotic shrimps can contribute to the associated biodiversity of reef corals. Among the host taxa, mushroom corals (Cnidaria: Anthozoa: Fungiidae) are known to harbour various groups of symbionts, including shrimps. Some but not all of these associated species are host-specific. Because data on the host specificity of shrimps on mushroom corals are scarce, shrimp spe- cies of the genus Periclimenes were collected from mushroom corals during fieldwork in Lembeh Strait, © RAUCH ET AL., 2019 | doi:10.1163/18759866-20191357 This is an open access article distributed under the terms of the prevailing cc-by license at the time of publication.

Hoeksema,2,4 Roland Butôt,2 and Jaaziel E. García-Hernández3 Abstract: The coral crab Fungicola fagei (Decapoda: Brachyura: Cryptochiridae) is recorded for the first time from the Hawaiian Islands, where it was discovered in a previously unknown association with the solitary, free-living mushroom coral Lobactis scutaria (Anthozoa: Scleractinia: Fungiidae). The associated crab species was discovered off Hilo on the island of Hawai‘i, where it appeared to be relatively common. It could have been previously overlooked because of its small size (max. ca. 1 cm long) and its hidden life style inside the host coral. Species identification is based on the morphology of the carapace and use of the cyto- chrome oxidase subunit I (COI ) barcode gene as molecular marker. Fungicola fagei is known from other localities in the Indo-West Pacific region, where it is only hosted by mushroom coral species of the genera Podabacia and Sandalolitha. The record of F.

Sabrina Pankey5 , Aki H. Ohdera4 , Monica Medina4 , David C. Plachetzki5* , Allen G. Collins1,6 and Joseph F. Ryan7,8* Abstract Background: The phylogeny of Cnidaria has been a source of debate for decades, during which nearly all-possible relationships among the major lineages have been proposed. The ecological success of Cnidaria is predicated on several fascinating organismal innovations including stinging cells, symbiosis, colonial body plans and elaborate life histories. However, understanding the origins and subsequent diversification of these traits remains difficult due to persistent uncertainty surrounding the evolutionary relationships within Cnidaria. While recent phylogenomic studies have advanced our knowledge of the cnidarian tree of life, no analysis to date has included genome-scale data for each major cnidarian lineage. Results: Here we describe a well-supported hypothesis for cnidarian phylogeny based on phylogenomic analyses of new and existing genome-scale data that includes representatives of all cnidarian classes. Our results are robust to alternative modes of phylogenetic estimation and phylogenomic dataset construction. We show that two popular phylogenomic matrix construction pipelines yield profoundly different datasets, both in the identities and in the functional classes of the loci they include, but resolve the same topology. We then leverage our phylogenetic resolution of Cnidaria to understand the character histories of several critical organismal traits.

For ease of navigation, this Annex is divided into seven sections: Annex 6A: Mammals pages 2 - 8 Annex 6B: Birds (to be reviewed in conjunction with Annex 5) pages 9-36 Annex 6C: Reptiles pages 37-44 Annex 6D: Amphibians pages 45-46 Annex 6E: Cartilaginous and bony Fishes pages 47-48 Annex 6F: Invertebrates other than corals pages 49-50 Annex 6G: Corals pages 51-86 In the column ‘Appendix’, the CITES Appendix in which the species or higher taxon is listed is given; in many but not all cases, the Annex in which the species is placed in EU regulation (A, B or C) is also listed. In Annexes 6A, 6C, 6D, 6E and 6F, multiple references are sometimes cited that each document the described nomenclatural change; in those cases, individual references within the table cell are separated by ‘##’. In Annexes 6B and 6G specific symbols are used to indicate nomenclatural splits, lumps and other changes, as follows: The symbol '<' is used to indicate species lumps, i.e. taxa currently recognised as separate, but that have been grouped together as synonym or subspecies under another name in the associated reference.
