Je le remercie vivement de m’avoir accueillie au sein de son laboratoire et d’avoir accepté de présider ce jury de thèse. Je souhaite exprimer tous mes remerciements à mes deux directeurs de thèse : Guy Bachelet, pour avoir permis que cette aventure de quatre ans se réalise, pour avoir financé divers colloques grâce à ses budgets et pour avoir corrigé ce manuscrit malgré le peu de temps laissé… mais heureusement les plumes et le goudron ont été évités de peu… Xavier de Montaudouin, pour m’avoir, déjà lorsque j’étais encore toute petite avec mes longues nattes, donné la chance de découvrir le monde fabuleux des parasites. Je vous remercie plus que grandement pour votre confiance tout au long de ces quasi 5 années passées ensemble, de votre attention, de vos conseils avisés, de votre bonne humeur permanente, de votre soutien sur le terrain jusqu’aux manip. de motopompe ‘by night’ et j’en passe car la liste des remerciements serait trop grande. Enfin pour conclure, il est vrai que de partager votre bureau a ses avantages : réponses immédiates à mes nombreuses questions, partage de boîtes de chocolats…etc… En revanche, vous me devez quasi 4 ans de salaire en tant que secrétaire de M. de Montaudouin…. Mais, je me contenterai d’une part du gâteau super facile à faire et dont vous avez la recette… Je souhaite également exprimer ma profonde gratitude aux rapporteurs et membres du Jury : à Madame le Professeur Fernanda Russell-Pinto, pour avoir accepté d’être rapporteur dans ce jury de thèse, pour m’avoir initiée à la découverte des parasites en 3D grâce à la M.E.B. et pour m’avoir accueillie par deux fois à Porto toujours avec beaucoup de gentillesse et de disponibilité. Obrigada. à Monsieur Serge Morand, Directeur de Recherches au CNRS de Montferrier sur Lez, pour avoir apporté son regard avisé sur ce travail de thèse, en acceptant d’être rapporteur mais aussi en me donnant de précieux conseils et avis lors de la soutenance. à Monsieur Frédéric Thomas, Chargé de Recherches au CNRS de Montpellier, examinateur de cette thèse, pour avoir accepté de faire parti de ce jury, malgré un emploi du temps chargé et des nuits à chasser des criquets parasités. Merci également pour les pistes à creuser pour le futur dont la recherche de post-doc. I wish to thank Dr Kurt Thomas Jensen for taking part in this PhD examining board and consequently disrupting his holidays travel way. I’m also very grateful for his review and useful advices concerning the article published in DAO (2002); for reviewing this manuscript and attending the oral communication despite the French language I used in both cases. Je suis très honorée de votre présence à tous dans mon jury de thèse. Je ne saurai oublier toute l’équipe du LOB : Merci Isa pour m’avoir cédé ta place en DEA, me laissant l’opportunité de réaliser cette thèse passionnante. Pour moi il est évident que tu fais toujours parti de la ‘parasite familly’. Hugues, tu te doutais bien qu’un minuscule paragraphe ne résume pas quasi 5 années de vie commune au sein du labo 5. Tout d’abord merci pour ton amitié, ta gentillesse, ta patience, ta capacité à écouter mes blagues à 2 frs 6 sous, pour avoir supporté mes humeurs parfois dévastatrices et m’avoir lors de ces moments là appris à modérer mes écrits et mes dires et merci ….. pour tes talents culinaires lors des pique-niques terrain…(1/0 pour moi).

In vitro cultivation of digeneans would aid the development of effective treatments and studies of the biology of the parasites. The goal of this study was to optimize culture conditions for the trematode, Gynaecotyla adunca. Metacercariae of the parasite from fiddler crabs, Uca pugnax, excysted in trypsin, were incubated overnight to permit fertilization, and were cultured in different conditions to find those that resulted in maximum worm longevity and egg production. When cultured in media lacking serum, worms lived longer in Hanks balanced salt solution and Dulbecco’s Modified Eagle medium/F-12 (DME/F-12) than in RPMI-1640 but produced the most eggs in DME/F-12. Worm longevity and egg production increased when worms were grown in DME/F-12 supplemented with 20% chicken, horse, or newborn calf serum but the greatest number of eggs was deposited in cultures containing horse or chicken serum.

A loss of natural enemies, such as parasites, is one mechanism proposed to contribute to that success. While several studies have shown NIS are initially less parasitized than native conspecifics, fewer studies have investigated whether parasite richness changes over time. Moreover, evaluating the role that parasites have in invaded communities requires not only an understanding of the parasite diversity of NIS but also the species with which they interact; yet parasite diversity in native species may be inadequately quantified. In our study, we examined parasite taxonomic richness, infection prevalence, and infection intensity in the invasive Asian shore crab Hemigrapsus sanguineus De Haan, 1835 and two native mud crabs (Panopeus herbstii Milne-Edwards, 1834 and Eurypanopeus depressus Smith, 1869) in estuarine and coastal communities along the east coast of the USA.

  • The Influence of Ocean Warming on the Provision of Biogenic Habitat by Kelp Species

Smale (Marine Biological Association of the UK) Secondary Supervisors: Professor Stephen J. Hawkins (Marine Biological Association of the UK, University of Southampton), Dr Pippa Moore (Aberystwyth University) i UNIVERSITY OF SOUTHAMPTON ABSTRACT FACULTY OF NATURAL AND ENVIRONMENTAL SCIENCES Ocean and Earth Sciences Doctor of Philosophy THE INFLUENCE OF OCEAN WARMING ON THE PROVISION OF BIOGENIC HABITAT BY KELP SPECIES by Harry Andrew Teagle Kelp forests represent some of the most productive and diverse habitats on Earth, and play a critical role in structuring nearshore temperate and subpolar environments. They have an important role in nutrient cycling, energy capture and transfer, and offer biogenic coastal defence. Kelps also provide extensive substrata for colonising organisms, ameliorate conditions for understorey assemblages, and generate three-dimensional habitat structure for a vast array of marine plants and animals, including a number of ecologically and commercially important species. This thesis aimed to describe the role of temperature on the functioning of kelp forests as biogenic habitat formers, predominantly via the substitution of cold water kelp species by warm water kelp species, or through the reduction in density of dominant habitat forming kelp due to predicted increases in seawater temperature. The work comprised three main components; (1) a broad scale study into the environmental drivers (including sea water temperature) of variability in holdfast assemblages of the dominant habitat forming kelp in the UK, Laminaria hyperborea, (2) a comparison of the warm water kelp Laminaria ochroleuca and the cold water kelp L.

Galaktionovl, Jan Ove ~ustnes~l* 'Zoological Institute of the Russian Academy of Sciences, White Sea Biological Station, Universitetskaja nab., 1, St Petersburg, 199034, Russia 'Norwegian Institute for Nature Research, Department of Arctic Ecology, The Polar Environmental Centre. 9296 Tromse, Norway ABSTRACT: An important component of the parasite fauna of seabirds in arctic regions are the flukes (Digena).Different species of digeneans have life cycles whch may consist of 1 intermediate host and no free-living larval stages, 2 intermediate hosts and 1 free-living stage, or 2 intermediate hosts and 2 free-living larval stages. This study examined the distribution of such parasites in the intertidal zones of the southern coast of the Barents Sea (northwestern Russia and northern Norway) by investigating 2 species of periwinkles (Littorina saxatilis and L. obtusata) which are intermediate hosts of many species of digeneans. A total of 26020 snails from 134 sampling stations were collected. The study area was divided into 5 regions, and the number of species, frequency of occurrence and prevalence of different digenean species and groups of species (depending on life cycle complexity) were compared among these regions, statistically controlling for environmental exposure. We found 14 species of digeneans, of which 13 have marine birds as final hosts. The number of species per sampling station increased westwards, and was hlgher on the Norwegian coast than on the Russian coast.

Adams et A. Adams, 1852 as currently conceived, are reviewed. With the exception of O. semicostata (Montagu, 1803) and O. aculeus (Gould, 1841) that range mostly in the European North-Eastern Atlantic and are rarely found in the Western Mediterranean, this genus is represented by six species with rather limited ranges: O. dimassai Amati et Nofroni, 1991; O. josae Moolenbeek et Hoenselaar, 1987; O. guzmani Hoenselaar et Moolenbeek, 1987; O. tarifensis Hoenselaar et Moolenbeek, 1987; O. gianninii (Nordsieck, 1974) and O. oliverioi Smriglio et Mariottini, 2000. A further possibly undescribed species is figured. For all species comparative morphometrics are provided. Onoba josae Moolenbeek et Hoenselaar, 1987 is here recorded for the first time in Italy, with the easternmost locality in this range.

Discovery Sheet 51 Conservation Designation: Inishmore Island SAC 000213, pNHA 000213 General description: Situated on the northwest coast of Inishmore, 2.5km northwest of the town of Kilmurvy (Cill Mhuirbhigh). A small (4ha), shallow (<2m) natural karst lagoon with a cobble barrier. The bed of the lagoon is mostly limestone pavement and stones, with soft mud in the centre and cobbles along the barrier. Seawater presumably percolates through the cobble barrier but also through limestone fissures. Salinity is close to that of seawater and measured 33.5psu at the time of sampling (8/8/2006). Figure 45.1 Location map of Loch Dearg, Inishmore. 249 IL045 Loch Dearg Loch Dearg was surveyed on 8/8/06 for aquatic fauna and flora. This is a small lagoon and was sampled as a single sampling station along the southern shore of the lagoon (Figure 45.2, Table 45.1) This part of the lagoon is quite homogeneous, comprised of limestone pavement and stones, with soft mud in central areas. The northern shore is a relatively steep mobile bank of cobbles with no apparent vegetation and very little fauna.
