Kauehi (French Polynesia) Aide simple à la plus commune mollusques marins de l'Atoll de Kauehi Guida Semplice ai più comuni Molluschi Marini dell’Atollo di Kauehi Claudio Fanelli member of International Teaching Malacology Project versione 02 .00 pagina 1 Ce guide fait partie d'une série consacrée à l'enseignement de malacología à des événements spécifiques ou dans des cours d'école, et avec une référence particulière à malacofaune des endroits bien définis. Dans ce cas, il se réfère à Kauhi atoll de Polynésie française. Nous voulions illustrer la discussion pour les espèces les plus communes, à savoir ceux qui le néophyte peut effectivement trouver le long de la côte. Dans ce sens, nous avons examiné, parmi les espèces les plus communes, seuls ceux qui ont plus de 5 mm Questa guida è parte di una collana dedicata all’insegnamento della malacologia in specifiche manifestazioni o in lezioni scolastiche e con particolare riferimento alla malacofauna di ben determinate località. In questo caso si fa riferimento all’Atollo di Kauehi nella Polinesia Francese. Si è voluto esemplificare la trattazione alle specie più comuni, quelle cioè che il neofita può realmente rinvenire lungo le coste. In questo senso sono state esaminate, tra le specie più comuni, soltanto quelle con dimensioni superiori ai 5 millimetri pagina 2 Ce travail fait partie du Projet Iinternational pour l'Enseignement de la Malacologie et se consacre à des activités éducatives. Donc, il est à but non lucratif et ne peut être vendu ou utilisé à des fins commerciales. Nous devons remercier tous ceux qui ont mis à disposition leurs photos. Ils sont utilisés uniquement à des fins éducatives dans le projet et ont détaillé scientifique, éducatif et à but non lucratif. Les images utilisées sont la propriété de l'affiche et à cet effet sur les images de la base de données photographique du projet est écrit leur nom. Dans ce travail sont écrits seulement les noms autres que les auteurs de ce volume. Cette première édition sera sûrement l'objet de révisions faites dans le cadre du projet, basé sur des collaborations avec les autres pays participants. Questo lavoro è parte del Progetto Internazionale per l’Insegnamento della Malacologia ed è dedicato ad attività educative. Quindi non è per profitto e non può essere venduto o usato per fini commerciali. Dobbiamo un ringraziamento a tutti coloro che ci hanno messo a disposizione le loro foto. Queste sono usate esclusivamente per finalità educative all’interno del progetto e hanno requisiti scientifici, educativi e non per profitto. Le immagini usate rimangono di proprietà degli autori e a questo scopo sulle immagini del database fotografico del progetto è scritto il loro nome. In questo lavoro sono scritti solo i nomi diversi da quelli degli autori di questo volume. Questa prima edizione sarà sicuramente oggetto di revisioni effettuate, nell'ambito del progetto, sulla base di collaborazioni con gli altri paesi partecipanti. pagina 3 Ayant pris part à la campagne de la recherche malacologique dans le Parc de la Réserve de biosphère de la Commune de Fakarava nous nous demandions si il y avait la possibilité de créer une série de guide simple aux mollusques communs à cette région. La quantité de données et d'images disponibles nous a permis de déterminer les espèces les plus communes, mais avec un critère différent des autres guides de cette série. Le projet n'a pas été prévu pour des activités destinées à ce genre d'information et nous, par conséquent, dirigé de choisir un critère lié à la quantité d'individus observés pour chaque espèce. Nous avons fixé cette valeur à une observation plus de 10 spécimens. Cela ne garantit pas qu'il est "espèces communes" mais elle nous donne une bonne chance qu'ils sont. Dans ces œuvres, reportez- vous à la Polynésie montrer un montant espèces «petits» que la forme d'atolls et de leurs récifs coralliens, il ne permet pas une forte prévalence de bivalves et encourage le développement de micromolluschi plus que la macro. Avendo preso parte alla Campagna di Ricerche Malacologiche nel Parco della Riserva della Biosfera del Comune di Fakarava ci siamo chiesti se ci fosse stata la possibilità di realizzare una serie di Semplici Guide ai Molluschi più comuni di questa area. La mole di dati e di immagini disponibili ci ha permesso di determinare le specie più comuni ma con un criterio diverso dalle altre guide di questa serie. Nel progetto non era prevista una attività destinata a questo tipo di informazioni e ci siamo, quindi, orientati a scegliere un criterio collegato ai quantitativi di esemplari osservati per ciascuna specie. Abbiamo prefissato questo valore ad una osservazione superiore ai 10 esemplari. Questo non garantisce che si tratti di “specie comuni” ma ci offre buone probabilità che lo siano. In questi lavori riferiti alla Polinesia mostreremo una quantità “ridotta” di specie poichè la conformazione degli atolli e delle loro barriere coralline, non consente una alta diffusione dei bivalvi e favorisce lo sviluppo dei micromolluschi più che dei macro. pagina 4 Recherche compagnon parmi les espèces marines en Polynésie Française: Atoll de Kauehi Ricerca guidata tra le specie marine della Polinesia Francese: Atollo di Kauehi Ce guide vous aidera à identifier le nom de l'espèce de l'enveloppe que vous tenez.

Certains ont abandonné la construction de la coque et sont appelés «limaces de mer" Quella dei Gasteropodi è la classe più numerosa e raggruppa quei molluschi che hanno la conchiglia composta da un solo pezzo conico avvolto ad elica. Alcuni hanno abbandonato la costruzione della conchiglia e vengono chiamati "nudibranchi" page 6 ***** BIVALVIA ***** Dans cette classe, nous trouvons ces mollusques qui ont adopté un abri comme une coquille composée de deux parties mobiles, vannes, joints par une charnière et sommes donc dit bivalves In questa classe troviamo quei molluschi che hanno adottato come riparo un guscio composto da due parti mobili, valve, unite da una cerniera e sono quindi detti Bivalvi page 31 Ces autres classes ne sont pas très commun dans Niau, nous avons ajouté pas des photos.. Queste altre classi non sono molto comuni in Aratika e quindi non abbiamo inserito foto. ***** POLIPLACOPHORA *****A Non molto diffusa nel Mediterraneo, questa classe racchiude animali con la conchiglia composta da 8 placche tenute unite da un legamento organico. Not very common in the Mediterranean, this class includes animals with shells composed of 8 plates held together by an organic ligament. ***** SCAPHOPODA ***** Una conchiglia fatta a forma di "zanna di elefante" o di "scafo", da cui il nome Scafopodi, contraddistingue questa classe A shell shaped like a "elephant tusk" or "hull", hence the name Scafopodi, distinguishes this class ***** CEPHALOPODA ***** Chiamati così perchè hanno il loro sistema nervoso racchiuso nel "piede". Spesso sprovvisti di conchiglia che , in alcuni casi, si è ridotta assumendo la forma di un osso interno fatto come una "penna". So called because their nervous system is enclosed into their "foot". Often without a shell that, in some cases, has been reduced taking the shape of a bone-shaped "pen" inside. pagina 6 GASTROPODA pagina 7 Scutellastra flexuosa (Quoy & Gaimard, 1834) mm 20-56 Trochus niloticus Linnaeus, 1767 mm 24-39 Microtis rubra (Lamarck, 1822) mm 5-7 pagina 8 Turbo argyrostomus argyrostomus (Linnaeus, 1758) mm 30-63 Turbo petholatus petholatus (Linnaeus, 1758) mm Astralium rhodostoma Lamarck, 1822 mm 20-50 pagina 9 Nerita plicata Linnaeus, 1758 mm 13-24 Puperita bensoni (Recluz, 1850) mm 8-13 Phenacolepas pulchella Lischke, 1871 mm pagina 10 Cerithium columna Sowerby I, 1834 mm 20-33 Cerithium echinatum Lamarck, 1822 mm 30-70 pagina 11 Cerithium nesioticum Pilsbry & Vanatta, 1906 mm 18-20 Cerithium punctatum Bruguiere., 1792 mm 10-20

The lagoon of an atoll is separated from the ocean by a rim. As the rim controls the flux of water between ocean and lagoon, its structure is one of the major forcing factors of the biological processes that depend on the renewal rate of lagoonal water. Characterizing rim structure and its degree of hydro­ dynamic aperture is mandatory for comparing the functioning of different atoll lagoons. This paper characterizes at landscape scale the different types of rims of the atolls of the Tuamotu Archipelago (French Polynesia) using SPOT HRV multi-spectral images. The classification of 117 segments of rims highlights nine different rims.

Current statusof the endangeredTuamotu Sandpiper or Titi Prosobonia cancellataand recommendedactions for its recovery.Wader StudyGroup Bull. 105: 93-100. The TuamotuSandpiper or Titi is the only survivingmember of the Tribe Prosoboniiniand is confinedto easternPolynesia. Formerly distributedthroughout the Tuamotu Archipelago,it has been decimatedby mammalianpredators which now occuron nearlyall atollsof the archipelago.Isolated sandpiper populations are currentlyknown from only four uninhabitedatolls in the Tuamotu.Only two of theseare currentlyfree of mammalianpredators, such as cats and rats, and the risks of rat invasionon themare high. This paper outlines tasksnecessary in the shortterm (within five years)to securethe species,together with longerterm actions neededfor its recovery.Short-term actions include increasing the securityof existingpopulations, surveying for otherpotential populations, eradicating mammalian predators on key atolls,monitoring key populations, and preparing a recovery plan for the species. Longer term actions necessaryfor recovery include reintroductions,advocacy and research programmes. INTRODUCTION ecologyof the TuamotuSandpiper as completelyas is cur- rently known, assessesthe

  • A Comparison of Commercial Sea Cucumber Communities in the French Polynesia and New Caledonia Atolls Listed As UNESCO Man and Biosphere and World Heritage Areas
    SPC Beche-de-mer Information Bulletin #40 – March 2020 5 A comparison of commercial sea cucumber communities in the French Polynesia and New Caledonia atolls listed as UNESCO Man and Biosphere and World Heritage Areas Serge Andréfouët1* and Amélie Tagliaferro1 Abstract Sea cucumber communities in the UNESCO2 Man and the Biosphere Fakarava Reserve of French Polynesia and in the Entre- casteaux group of the Lagoons of New Caledonia’s World Heritage Area were assessed in 2012–2013. These two UNESCO- listed areas only include atolls, of various sizes and depth. The 2012–2013 period marked the official end of recent exploitations of sea cucumbers in both areas. The same survey methodology was used at both locations, which allowed us to compare the commercial communities. The Entrecasteaux group had more commercial species than Fakarava Reserve, but densities overall were similar. Bohadschia was the most abundant genus in the Man and Biosphere Reserve, while Thelenota ananas was the most abundant species in Entrecasteaux. Compared with many sites in the Pacific, these atolls still harbour significant sea cucumber populations, and it is expected that their status will remain positive in 2020 due to their protection and management. The two locations, however, have been fished since at least 2016: Entrecasteaux is exposed to international poaching, and several of the Fakarava Reserve atolls are legally fished every year. This exploitation, legal or illegal, calls for the periodic re-assessment of the status of sea cucumbers through dedicated holothurian surveys. Key-words: UNESCO, Man and the Biosphere, Fakarava Reserve, Entrecasteaux, World Heritage Area, Lagoons of New Caledonia, Atoll Introduction also benefits since 2018 from a new zoning plan with several natural reserves and strict nature reserves3.

Marine protected areas Meanwhile, some areas are internationally recognized nes protégées and awarded by UNESCO’s “Man and Biosphere” program in French Polynesia (Fakarava atolls) and by the RAMSAR convention on the international importance of wetlands (Moorea lagoon). French Polynesia also host traditional community-based management measures such as the “Rahui”, which are still used nowadays in Rapa and Maiao, for instance. Finally, French Polynesia has marine sanctuaries covering the entire waters under national jurisdiction for marine mammals and sharks. in partnership with : Crédits: P.Bachet/Au vent des îles ; S.D.

  • Particulate Organic Matter in Sixteen Tuamotu Atoll Lagoons (French Polynesia)
    MARINE ECOLOGY PROGRESS SERIES Published May 22 Mar Ecol Prog Ser I Particulate organic matter in sixteen Tuamotu atoll lagoons (French Polynesia) Loi'c Charpyl-*,Philippe Dufourl, Nicole Garcia2 'ORSTOM. Centre d'Oceanologie de Marseille, Rue de la Batterie des Lions, F-13007 Marseille, France 'LOB OSU, Luminy, 163 AV. de Luminy, F-13288 Marseille Cedex 09, France ABSTRACT. The stand~ngstock and chemical composition of suspended particles were monitored In 16 Tuamotu atoll lagoons and surrounding oceanic water between 1983 and 1996 Temporal and spatial variability was estimated from 18 surveys performed in Takapoto. Atoll lagoon partlculate organic matter (POM) concentrations were compared using data taken during the same months (March and November) and at the same time (morning). It appears that the lagoonal particulate organic carbon concentration depends on the latltude of each lagoon. We interpret this result as an influence of the waters deriving from the Peruvian and equatorial upwellings. Phytoplankton biomass (chlorophyll) concentration was inversely related to the water exchange between lagoon and ocean. Therefore, the best atolls for pearl oyster farming seem to be those located north of the Tuamotu Archipelago and with snlall exchange with the occan. POM concentration cvas 2 to 5 tunes higher in the atoll lagoons than in the surrounding oceanlc water, wlth a hlgher C:N ratio and a lower N:P ratio. The small size of organic particles (70'% < 3 pm) and the low contl-ibution of phytoplankton to particulate organlc carbon (POC) (S to 19%) in the lagoons must be taken into account when calculating the potential of pearl oysters, which cannot exceed the nutritional potential of Tuamotu atoll lagoons.
