Kumavath - Email: [email protected]; *Corresponding author Received August 14, 2014; Accepted August 16, 2014; Published September 30, 2014 Abstract: Turritopsis nutricula (T. nutricula) is the one of the known reported organisms that can revert its life cycle to the polyp stage even after becoming sexually mature, defining itself as the only immortal organism in the animal kingdom. Therefore, the animal is having prime importance in basic biological, aging, and biomedical researches. However, till date, the genome of this organism has not been sequenced and even there is no molecular phylogenetic study to reveal its close relatives. Here, using phylogenetic analysis based on available 16s rRNA gene and protein sequences of Cytochrome oxidase subunit-I (COI or COX1) of T. nutricula, we have predicted the closest relatives of the organism. While we found Nemopsis bachei could be closest organism based on COX1 gene sequence; T. dohrnii may be designated as the closest taxon to T. -
1 Creating a Species Inventory for a Marine Protected Area: the Missing
Katherine R. Rice NOAA Species Inventory Project Spring 2018 Creating a Species Inventory for a Marine Protected Area: The Missing Piece for Effective Ecosystem-Based Marine Management Katherine R. Rice ABSTRACT Over the past decade, ecosystem-based management has been incorporated into many marine- management administrations as a marine-conservation tool, driven with the objective to predict, evaluate and possibly mitigate the impacts of a warming and acidifying ocean, and a coastline increasingly subject to anthropogenic control. The NOAA Office of National Marine Sanctuaries (ONMS) is one such administration, and was instituted “to serve as the trustee for a network of 13 underwater parks encompassing more than 600,000 square miles of marine and Great Lakes waters from Washington state to the Florida Keys, and from Lake Huron to American Samoa” (NOAA, 2015). The management regimes for nearly all national marine sanctuaries, as well as other marine protected areas, have the goal of managing and maintaining biodiversity within the sanctuary. Yet none of those sanctuaries have an inventory of their known species nor a standardized protocol for measuring or monitoring species biodiversity. Here, I outline the steps required to compile a species inventory for an MPA, but also describe some of stumbling blocks that one might encounter along the way and offer suggestions on how to handle these issues (see Appendix A: Process for Developing the MBNMS Species Inventory (PD-MBNMS)). This project consists of three research objectives: 1. Determining what species inventory efforts exist, how they operate, and their advantages and disadvantages 2. Determining the process of creating a species inventory 3. -

The seasonal abundance and distribution of the dominant species of hydromedusae along a salinity gradient within the Gironde Estuary, Atlantic coast of France, were evaluated based on monthly surveys, June 2013 to April 2014. The results confirmed the presence of three species considered to be introduced in many coastal ecosystems around the world: Nemopsis bachei (Agassiz, 1849), Blackfordia virginica (Mayer, 1910), and Maeotias marginata (Modeer, 1791). These species were found at salinities ranging from 0 to 22.9 and temperatures ranging from 14.5 to 26.6 ºC, demonstrating their tolerance to a wide range of estuarine environmental conditions. -

CNIDARIA Corals, Medusae, Hydroids, Myxozoans

Dawson, OscaR OcaÑA V., WILLEM VERvooRT, GARY WILLIAMS, JEANETTE E. Watson, DENNIS M. OPREsko, PETER SCHUCHERT, P. MICHAEL HINE, DENNIS P. GORDON, HAMISH J. CAMPBELL, ANTHONY J. WRIGHT, JUAN A. SÁNCHEZ, DAPHNE G. FAUTIN his ancient phylum of mostly marine organisms is best known for its contribution to geomorphological features, forming thousands of square Tkilometres of coral reefs in warm tropical waters. Their fossil remains contribute to some limestones. Cnidarians are also significant components of the plankton, where large medusae – popularly called jellyfish – and colonial forms like Portuguese man-of-war and stringy siphonophores prey on other organisms including small fish. Some of these species are justly feared by humans for their stings, which in some cases can be fatal. Certainly, most New Zealanders will have encountered cnidarians when rambling along beaches and fossicking in rock pools where sea anemones and diminutive bushy hydroids abound. In New Zealand’s fiords and in deeper water on seamounts, black corals and branching gorgonians can form veritable trees five metres high or more. In contrast, inland inhabitants of continental landmasses who have never, or rarely, seen an ocean or visited a seashore can hardly be impressed with the Cnidaria as a phylum – freshwater cnidarians are relatively few, restricted to tiny hydras, the branching hydroid Cordylophora, and rare medusae. Worldwide, there are about 10,000 described species, with perhaps half as many again undescribed. All cnidarians have nettle cells known as nematocysts (or cnidae – from the Greek, knide, a nettle), extraordinarily complex structures that are effectively invaginated coiled tubes within a cell. -

Abstract Background: Polypodium hydriforme is a parasite with an unusual life cycle and peculiar morphology, both of which have made its systematic position uncertain. Polypodium has traditionally been considered a cnidarian because it possesses nematocysts, the stinging structures characteristic of this phylum. However, recent molecular phylogenetic studies using I8S rDNA sequence data have challenged this interpretation, and have shown that Polypodium is a close relative to myxozoans and together they share a closer affinity to bilaterians than cnidarians. -

Previous phylogenetic analyses show strong support for Hydroidolina monophyly, but the relationships between and within its subgroups remain uncertain. In an effort to further clarify hydroidolinan relationships, we performed phylogenetic analyses on 97 hydroidolinan taxa, using DNA sequences from partial mitochondrial 16S rDNA, nearly complete nuclear 18S rDNA and nearly complete nuclear 28S rDNA. Our findings are consistent with previous analyses that support monophyly of Siphonophorae and Leptothecata and do not support monophyly of Anthoathecata nor its component subgroups, Filifera and Capitata. Instead, within Anthoathecata, we find support for four separate filiferan clades and two separate capitate clades (Aplanulata and Capitata sensu stricto). Our data however, lack any substantive support for discerning relationships between these eight distinct hydroidolinan clades. -

DAVID BURKE Gulf Coast Research Laboratory, Ocean Springs, Mississippi 39564 ABSTRACT Investigations were made in Mississippi Sound and adjacent waters from March 1968 through March 1971 to record the occurrence and seasonality of planktonic cnidarians. About 700 plankton samples were taken from estuarine and oceanic areas. From these samples, 26 species of hydromedusae were identified, 12 of which were collected from Mis- sissippi Sound. In addition, 25 species of siphonophorae were identified from Mississippi waters, although only 6 species were collected in Mississippi Sound. From an examination of about 500 trawl samples taken during this period, 10 species of Scyphozoa were found in Mississippi waters, 6 of which occurred in Mississippi Sound.

Bacterial Communities Associated with Scyphomedusae at Helgoland Roads
Marine Biodiversity https://doi.org/10.1007/s12526-018-0923-4 ORIGINAL PAPER Bacterial communities associated with scyphomedusae at Helgoland Roads Wenjin Hao1 & Gunnar Gerdts2 & Sabine Holst3 & Antje Wichels2 Received: 31 August 2017 /Revised: 21 September 2018 /Accepted: 26 September 2018 # The Author(s) 2018 Abstract Different modes of asexual and sexual reproduction are typical for the life history of scyphozoans, and numerous studies have focused on general life history distribution, reproductive strategies, strobilation-inducing factors, growth rates, and predatory effects of medusae. However, bacteria associated with different life stages of Scyphozoa have received less attention. In this study, bacterial communities associated with different body compartments and different life stages of two common scyphomedusae (Cyanea lamarckii and Chrysaora hysoscella) were analyzed via automated ribosomal intergenic spacer analysis (ARISA). We found that the bacterial community associated with these two species showed species- specific structuring. In addition, we observed significant differences between the bacterial communities associated with the umbrella and other body compartments (gonads and tentacles) of the two scyphomedusan species. Bacterial commu- nity structure varied from the early planula to the polyp and adult medusa stages. We also found that the free-living and particle-associated bacterial communities associated with different food sources had no impact on the bacterial community associated with fed polyps.
