Changing Jellyfish Populations: Trends in Large Marine Ecosystems
CHANGING JELLYFISH POPULATIONS: TRENDS IN LARGE MARINE ECOSYSTEMS by Lucas Brotz B.Sc., The University of British Columbia, 2000 A THESIS SUBMITTED IN PARTIAL FULFILLMENT OF THE REQUIREMENTS FOR THE DEGREE OF MASTER OF SCIENCE in The Faculty of Graduate Studies (Oceanography) THE UNIVERSITY OF BRITISH COLUMBIA (Vancouver) October 2011 © Lucas Brotz, 2011 Abstract Although there are various indications and claims that jellyfish have been increasing at a global scale in recent decades, a rigorous demonstration to this effect has never been presented. As this is mainly due to scarcity of quantitative time series of jellyfish abundance from scientific surveys, an attempt is presented here to complement such data with non- conventional information from other sources. This was accomplished using the analytical framework of fuzzy logic, which allows the combination of information with variable degrees of cardinality, reliability, and temporal and spatial coverage. Data were aggregated and analysed at the scale of Large Marine Ecosystem (LME). Of the 66 LMEs defined thus far, which cover the world’s coastal waters and seas, trends of jellyfish abundance (increasing, decreasing, or stable/variable) were identified (occurring after 1950) for 45, with variable degrees of confidence. Of these 45 LMEs, the overwhelming majority (31 or 69%) showed increasing trends. Recent evidence also suggests that the observed increases in jellyfish populations may be due to the effects of human activities, such as overfishing, global warming, pollution, and coastal development. Changing jellyfish populations were tested for links with anthropogenic impacts at the LME scale, using a variety of indicators and a generalized additive model. Significant correlations were found with several indicators of ecosystem health, as well as marine aquaculture production, suggesting that the observed increases in jellyfish populations are indeed due to human activities and the continued degradation of the marine environment. -

Ectosymbiotic Behavior of Cancer Gracilis and Its Trophic Relationships with Its Host Phacellophora Camtschatica and the Parasitoid Hyperia Medusarum
MARINE ECOLOGY PROGRESS SERIES Vol. 315: 221–236, 2006 Published June 13 Mar Ecol Prog Ser Ectosymbiotic behavior of Cancer gracilis and its trophic relationships with its host Phacellophora camtschatica and the parasitoid Hyperia medusarum Trisha Towanda*, Erik V. Thuesen Laboratory I, Evergreen State College, Olympia, Washington 98505, USA ABSTRACT: In southern Puget Sound, large numbers of megalopae and juveniles of the brachyuran crab Cancer gracilis and the hyperiid amphipod Hyperia medusarum were found riding the scypho- zoan Phacellophora camtschatica. C. gracilis megalopae numbered up to 326 individuals per medusa, instars reached 13 individuals per host and H. medusarum numbered up to 446 amphipods per host. Although C. gracilis megalopae and instars are not seen riding Aurelia labiata in the field, instars readily clung to A. labiata, as well as an artificial medusa, when confined in a planktonkreisel. In the laboratory, C. gracilis was observed to consume H. medusarum, P. camtschatica, Artemia franciscana and A. labiata. Crab fecal pellets contained mixed crustacean exoskeletons (70%), nematocysts (20%), and diatom frustules (8%). Nematocysts predominated in the fecal pellets of all stages and sexes of H. medusarum. In stable isotope studies, the δ13C and δ15N values for the megalopae (–19.9 and 11.4, respectively) fell closely in the range of those for H. medusarum (–19.6 and 12.5, respec- tively) and indicate a similar trophic reliance on the host. The broad range of δ13C (–25.2 to –19.6) and δ15N (10.9 to 17.5) values among crab instars reflects an increased diversity of diet as crabs develop. The association between C. -

Hyperia Galba in the North Sea Birgit Dittrich*
HELGOLANDER MEERESUNTERSUCHUNGEN Helgol&nder Meeresunters. 42, 79-98 (1988) Studies on the life cycle and reproduction of the parasitic amphipod Hyperia galba in the North Sea Birgit Dittrich* Lehrstuhl ffir Speziefle Zoologie und Parasitologie, Ruhr-Universit~t Bochum; D-4630 Bochum 1 and Biologische Anstalt Helgoland (Meeresstation); D-2192 Helgoland, Federal Republic of Germany ABSTRACT: The structure of a Hyperia galba population, and its seasonal fluctuations were studied in the waters of the German Bight around the island of Helgoland over a period of two years (1984 and 1985). A distinct seasonal periodicity in the distribution pattern of this amphipod was recorded. During summer, when its hosts - the scyphomedusae Aurelia aurita, Chrysaora hysoscella, Rhizo- stoma pulmo, Cyanea capillata and Cyanea lamarckn'- occur in large numbers, supplying shelter and food, a population explosion of H. galba can be observed. It is caused primarily by the relatively high fecundity of H. galba which greatly exceeds that of other amphipods: a maximum of 456 eggs was observed. The postembryonic development is completed in the medusae infested; only then are the young able to swim and search for a new host. The smallest fr4ely-swimming hyperians obtained from plankton samples were 2.6 mm in body size. The size classes observed as well as moult increment and moulting frequencies in relation to different temperatures suggest that two genera- tions are developed per year: a rapidly growing generation in summer and a slower growing generation in winter that shifts to a benthic mode of life and hibernation. For short periods, adult hyperians may become attached to zooplankters other than scyphomedusae. -

Planktonic Associations Between Medusae (Classes Scyphozoa and Hydrozoa) and Epifaunal Crustaceans
Planktonic associations between medusae (classes Scyphozoa and Hydrozoa) and epifaunal crustaceans Kaden Muffett and Maria Pia Miglietta Department of Marine Biology, Texas A&M University - Galveston, Galveston, Texas, United States ABSTRACT Jellyfish are known to carry various epibionts, including many of the subphylum Crustacea. However, the associations between gelatinous zooplankton and other invertebrates have been chronically overlooked. Crustacea, a massive clade of economically, ecologically, and culturally important species, includes many taxa that utilize gelatinous zooplankton for food, transport, and protection as both adults and juveniles. Here we compile 211 instances of epifaunal crustaceans recorded on Hydromedusae and Scyphomedusae from a century of literature. These include 78 identified crustacean species in 65 genera across nine orders found upon 37 Hydromedusa species and 48 Scyphomedusae. The crustacean life stage, location, nature of the association with the medusa, years, months, and depths are compiled to form a comprehensive view of the current state of the literature. Additionally, this review highlights areas where the current literature is lacking, particularly noting our poor understanding of the relationships between juvenile crabs of commercially valuable species and medusae.

'" t. AMPHIPOD : 1 I ,~j NE WSLETTER 3 V october 1973 This third issue of the Amphipod Newsletter is the first to appear lD off-set. This has become possible through the most welcome help of Zoo- Tax, a "Service CeYit er of Taxonorr.ic Zoology" in Lund, Sweden, and Zoo- Tax is also responsible for the distribution of this issue. Technical Pl'l)blems in connection wi th these changes have caused some delay in the 2oIT,Fleter: ,el"_t of this issue, but I hope this will be counteracted by increased quality and lowered cost: Zoo- Tax is incredibly cheap. I prem.ised to suggest a subscription fee in this lssue. I now propose a fee of 4. German Mark (BRD) annually (or rat'her; for 2 issues) , preferably to be paid by International Money Order to my address in TromS0. As far as I can see, ttis will be sufficient and it will even enable us to send the Newsletter cheaper ( or even free ) to a few COlleagues with very limited budgets. The first subscription will cover Newsletter 2 and 3, and it would be an advantage if many of you could at the same time pay the next subscription, so that I 'll have some credit. I all1 most grateful to those COlleagues who have sent me money earlier, and they 211'e of course not expected to pay now. In the next issue I shall give further details of the financia l situation; meanwhile I shall be glad to have your comments.
