DOCTORAL THESIS a Physio-Ecological Study of Ephyrae
DOCTORAL THESIS A Physio-ecological Study of Ephyrae of the Common Jellyfish Aurelia aurita s.l. (Cnidaria: Scyphozoa), with Special Reference to their Survival Capability under Starvation Zhilu Fu Graduate School of Biosphere Science Hiroshima University September 2014 DOCTORAL THESIS A Physio-ecological Study of Ephyrae of the Common Jellyfish Aurelia aurita s.l. (Cnidaria: Scyphozoa), with Special Reference to their Survival Capability under Starvation Zhilu Fu Department of environmental Dynamics and Management Graduate School of Biosphere Science Hiroshima University September 2014 Abstract The moon jellyfish Aurelia aurita s.l. is the most common scyphozoan jellyfish in the coastal waters around the world, and the mass occurrences of this species have been reported from various regions. In recent decades, A. aurita blooms have become increasingly prominent in East Asian seas, causing serious problems to human sectors such as fisheries and coastal power plant operations. Therefore, it is important to identify causes for the enhancement of A. aurita populations to forecast likely outbreaks prior to the season of medusa blooms. In the population dynamics of scyphozoan jellyfish, the following two factors are important to determine the size of adult (medusa) population: (1) the abundance of benthic polyps, which reproduce asexually and undergo seasonal strobilation to release planktonic ephyrae, and (2) the mortality of ephyrae before recruitment to the medusa stage. Although much knowledge has been accumulated about physio-ecology of the polyp stage by previous studies, only few studies have been conducted for the ephyra stage. The success for survival through larval stage is basically affected by two factors, viz. food availability and predation. -
Reported Siphonostomatoid Copepods Parasitic on Marine Fishes of Southern Africa
REPORTED SIPHONOSTOMATOID COPEPODS PARASITIC ON MARINE FISHES OF SOUTHERN AFRICA BY SUSAN M. DIPPENAAR1) School of Molecular and Life Sciences, University of Limpopo, Private Bag X1106, Sovenga 0727, South Africa ABSTRACT Worldwide there are more than 12000 species of copepods known, of which 4224 are symbiotic. Most of the symbiotic species belong to two orders, Poecilostomatoida (1771 species) and Siphonos- tomatoida (1840 species). The order Siphonostomatoida currently consists of 40 families that are mostly marine and infect invertebrates as well as vertebrates. In a report on the status of the marine biodiversity of South Africa, parasitic invertebrates were highlighted as taxa about which very little is known. A list was compiled of all the records of siphonostomatoids of marine fishes from southern African waters (from northern Angola along the Atlantic Ocean to northern Mozambique along the Indian Ocean, including the west coast of Madagascar and the Mozambique channel). Quite a few controversial reports exist that are discussed. The number of species recorded from southern African waters comprises a mere 9% of the known species. RÉSUMÉ Dans le monde, il y a plus de 12000 espèces de Copépodes connus, dont 4224 sont des symbiotes. La plupart de ces espèces symbiotes appartiennent à deux ordres, les Poecilostomatoida (1771 espèces) et les Siphonostomatoida (1840 espèces). L’ordre des Siphonostomatoida comprend actuellement 40 familles, qui sont pour la plupart marines, et qui infectent des invertébrés aussi bien que des vertébrés. Dans un rapport sur l’état de la biodiversité marine en Afrique du Sud, les invertébrés parasites ont été remarqués comme étant très peu connus. -
Towards Understanding the Phylogenetic History of Hydrozoa: Hypothesis Testing with 18S Gene Sequence Data*
SCI. MAR., 64 (Supl. 1): 5-22 SCIENTIA MARINA 2000 TRENDS IN HYDROZOAN BIOLOGY - IV. C.E. MILLS, F. BOERO, A. MIGOTTO and J.M. GILI (eds.) Towards understanding the phylogenetic history of Hydrozoa: Hypothesis testing with 18S gene sequence data* A. G. COLLINS Department of Integrative Biology and Museum of Paleontology, University of California, Berkeley, CA 94720, USA SUMMARY: Although systematic treatments of Hydrozoa have been notoriously difficult, a great deal of useful informa- tion on morphologies and life histories has steadily accumulated. From the assimilation of this information, numerous hypotheses of the phylogenetic relationships of the major groups of Hydrozoa have been offered. Here I evaluate these hypotheses using the complete sequence of the 18S gene for 35 hydrozoan species. New 18S sequences for 31 hydrozoans, 6 scyphozoans, one cubozoan, and one anthozoan are reported. Parsimony analyses of two datasets that include the new 18S sequences are used to assess the relative strengths and weaknesses of a list of phylogenetic hypotheses that deal with Hydro- zoa. Alternative measures of tree optimality, minimum evolution and maximum likelihood, are used to evaluate the relia- bility of the parsimony analyses. Hydrozoa appears to be composed of two clades, herein called Trachylina and Hydroidolina. Trachylina consists of Limnomedusae, Narcomedusae, and Trachymedusae. Narcomedusae is not likely to be the basal group of Trachylina, but is instead derived directly from within Trachymedusae. This implies the secondary gain of a polyp stage. Hydroidolina consists of Capitata, Filifera, Hydridae, Leptomedusae, and Siphonophora. “Anthomedusae” may not form a monophyletic grouping. However, the relationships among the hydroidolinan groups are difficult to resolve with the present set of data. -

Morphological analysis of several specimens showed distinct differences from other known semaestome spe- cies in the Mediterranean Sea and unquestionably identified them as belonging to a new pelagiid species within genus Pelagia. The new species is morphologically distinct from P. noctiluca, currently the only recognized valid species in the genus, and from other doubtful Pelagia species recorded from other areas of the world. Molecular analyses of mitochon- drial cytochrome c oxidase subunit I (COI) and nuclear 28S ribosomal DNA genes corroborate its specific distinction from P. noctiluca and other pelagiid taxa, supporting the monophyly of Pelagiidae. Thus, we describe Pelagia benovici sp. -

An assessment of water quality and plankton in key areas of the East Portland Special Fishery Conservation Area, Jamaica Dexter-Dean S. Colquhoun1*, Gale Persad-Ford1 and Mona K. Webber2 1- Department of Life Sciences, The University of the West Indies (U.W.I.), Mona Campus, Jamaica 2- Center for Marine Sciences, U.W.I., Mona Campus, Jamaica An ecological assessment of selected bays and associated shelf areas in East Portland, Jamaica was conducted from April 2014 to March 2015, prior to designation of the East Portland Special Fishery Conservation Area (E.P-S.F.C.A.); declared July 2016. The assessment employed planktonic and physicochemical indices which could be useful not only for selecting ideal areas for protection but also for generating baseline conditions for East Portland and highlighting potential areas of concern in a new fish sanctuary. These areas of concern were further examined and compared due to their potential impact on the overall efficacy of the E.P-S.F.C.A. Some physicochemical parameters, namely; salinity, Total Dissolved Solids (T.D.S.) and conductivity, proved useful for indicating riverine or enriched water masses in the bays. It was therefore evident that areas like West Channel and Blue Lagoon were experiencing elevated nutrients with relatively high nitrate (NO4-) concentrations (2.68 and 0.67 mg/L respectively); while areas in San San – fresh water seep 3- and Turtle Crawle displayed relatively high phosphate (PO4 ) concentrations (0.111 and 0.07 mg/L respectively). With regard to the biological (planktonic) communities, phytoplankton parameters displayed no significant differences between stations, however total chlorophyll a and distribution of specific size fractions were useful for confirming nutrient-loading at areas such as; Turtle Crawle and Blue Lagoon. -

Mercury can remain in aquatic environments for decades after initial release. Hat-making factories active in the late 19th to early 20th centuries directly released mercury nitrate into the Still River and its various tributaries. Rhinichthys atratulus, Blacknose Dace, is a common non-migratory minnow that is abundantly found in the Still River, CT. The aim of the study is to use R. atratulus to evaluate the environmental quality of historically mercury contaminated sites in comparison to sites with no previous history of point source mercury pollution. Historical sites have more mercury present in their sediment (~10% greater) which should lead to a higher accumulation of mercury in fish. Fish muscle tissues were used as indicators of mercury bioavailable to organisms at study sites. Other biological parameters (i.e. condition factors, age, and population size) were used to assess environmental quality but were found to be similar among populations. Mercury concentrations were unexpectedly highest in sites with no previous history of mercury pollution. These results shed light on the complexity of the mercury cycle and evolutionary processes that may be at play. If mercury is not bioavailable to fish, then muscle measurements will not accurately represent environmental quality.
