Abstract:
Objective: To assess the effect of vegetation cover on soil macrofauna, a study focused on the diversity of soil macrofauna inside and outside reforestation plots of the Great Green Wall in Senegal was carried out. Methodology: The sampling of macrofauna was performed according to the method recommended by the TSBF network (Tropical Soil Biology and Fertility). It involves isolating 10 ground plots along a transect of 50 meters chosen at random in each plot and outside of each plot. The macrofauna was sampled between February and July 2016 during the dry season Results: The results show, in order of importance Hymenoptera, Isoptera, Coleoptera, the Spiders, the isopods and springtails are the taxonomic groups of the study area. The density of each of these taxa is larger inside and outside of the plots. The vertical distribution of macrofauna shows that the 0-10 cm layer is more densely populated than the deeper layers. Conclusion: This study showed a low diversity of soil macrofauna in the area. It also shows that the vegetation cover affects the density of the macrofauna.

Abstract:
The Taphrognathus transatlanticus, Clydagnathus windsorensis, and Gnathodus zones, initially defined in the Codroy Group of Newfoundland, were identified in the Havre-aux-Maisons Formation of the Windsor Group of the Magdalen Islands, Quebec, Canada. Recognition of these zones permits correlation within the islands and with Newfoundland and Nova Scotia. The Taphrognathus transatlanticus and Clydagnathus windsorensis zones correlate with the lower and upper macrofaunal B Subzone, respectively, whereas the Gnathodus Zone corresponds to the C, D, and E macrofaunal subzones.Tectonism and plastic movement of sulphates and chlorides have resulted in fragmentation and transport of parts of the Havre-aux-Maisons Formation. The conodont zonation complements the macrofaunal zonation permitting correlation of fragmented blocks. When macrofaunas are scarce or absent the conodont zonation provides an alternative to one based on macrofauna only. It has been used effectively in assessing previous zonal determinations based on macrofauna.Conodonts of the Magdalen Islands are dominated by Clydagnathus, Cavusgnathus, Mestognathus, and Taphrognathus, all asymmetric cavusgnathiform genera. This dominance, the total lack of Gnathodus, abundant sulphates and chlorides, as well as foraminiferal and algal evidence, suggest that Lower Carboniferous conodonts of the Magdalen Islands lived in shallow-water shelf environments under conditions of fluctuating salinity.

Abstract:
Abstract. Previous studies have shown that microbially produced methane can be a dominant carbon source of lacustrine sedimentary macrofauna in eutrophic lakes, most likely through grazing on methane-oxidizing bacteria. Here we investigate the contributions of different carbon sources to macrofaunal biomass across five lakes in central Switzerland that range from oligotrophic to highly eutrophic. Macrofaunal communities change with trophic state, with chironomid larvae dominating oligotrophic and tubificid oligochaetes dominating eutrophic lake sediments. The 13C-isotopic data suggest that the average contribution of methane-derived carbon to the biomass of both macrofaunal groups is similar but consistently remains minor, ranging from only ∼1 % in the oligotrophic lake to at most 12 % in the eutrophic lakes. The remaining biomass can be explained by the assimilation of detritus-derived organic carbon. Low abundances of methane-cycling microorganisms in macrofaunal specimens, burrows, and surrounding sediment based on 16S ribosomal RNA (rRNA) gene sequences and copy numbers of genes involved in anaerobic and aerobic methane cycling (mcrA, pmoA) support the interpretation of isotopic data. Notably, 16S rRNA gene sequences of macrofauna, including macrofaunal guts, are highly divergent from those in tubes or sediments. Many macrofaunal specimens are dominated by a single 16S rRNA phylotype of Fusobacteria, α-, β-, γ-, or ε-Proteobacteria, Bacteroidetes, or Parcubacteria. This raises the question of whether dominant lake macrofauna live in so far uncharacterized relationships with detrital organic-matter-degrading bacterial endosymbionts.

Abstract:
Sponges act as important microhabitats in the marine environment and promote biodiversity by harboring a wide variety of macrofauna, but little is known about the magnitude and patterns of diversity of sponge-associated communities. This study uses DNA barcoding to examine the macrofaunal communities associated with Stylissa carteri in the central Saudi Arabian Red Sea, an understudied ecosystem with high biodiversity and endemism. In total, 146 operational taxonomic units (OTUs) were distinguished from 938 successfully-sequenced macrofauna individuals from 99 sponges. A significant difference was found in the macrofaunal community composition of S. carteri along a cross-shelf gradient using OTU abundance (Bray–Curtis dissimilarity index), with more amphipods associated with offshore sponges and more brittle stars and fishes associated with inshore sponges. The abundance of S. carteri also showed a gradient, increasing with proximity to shore. However, no significant differences in macrofaunal community composition or total macrofauna abundance were observed between exposed and sheltered sides of the reefs and there was no significant change in total macrofauna abundance along the inshore–offshore gradient. As climate change and ocean acidification continue to impact coral reef ecosystems, understanding the ecology of sponges and their role as microhabitats may become more important for understanding their full ramifications for biodiversity.

Abstract:
Meio- and macrofauna density and biomass were estimated at the OMEX-transect across the continental slope of the Goban Spur at water depths ranging from 208 to 4460 m in the north-east Atlantic. A linear increase in the ratio between meio- and macrofauna densities with increasing water depth was found. At the continental shelf meiofauna densities were ∼50 times higher than macrofauna densities, whereas in the abyss meiofauna densities were more than 1000 times higher. This change in ratio was due to a significant decrease in macrofauna densities with increasing water depth, whereas the meiofauna densities stayed more or less at the same level. The ratio in biomass between meio- and macrofauna showed a dip at ∼1000 m. At this depth macrofauna biomass was ∼55 times higher than meiofauna biomass, whereas at ∼4500 m macrofauna biomass was only about three times higher. Macrofauna biomass was high at ∼1000 m, due to the high mean individual weight of the macrofauna, whereas meiofauna biomass and mean individual weight were low at this depth.Meiofauna consisted of ∼90% nematodes. Within the macrofaunal fraction (>0.5 mm) a linear increase in the ratio between nematodes and macrofauna sensu stricto with depth was found. At the deepest station ∼20% of the macrofaunal fraction were nematodes, at the shallowest station only ∼2%. Thus, large nematodes became relatively more important with increasing water depth. Within the macrofauna a decrease in the abundance of filter- and surface deposit-feeders relative to the subsurface deposit-feeders with increasing water depth was observed, which may be related to a change in food input. As no decrease in mean individual weight with increasing water depth within either group could be observed, the change in meio:macrofauna ratios along the OMEX-transect merely reflects a change in taxonomic (functional) composition, rather than a change in size.

Abstract:
Soixante-deux taxons benthiques ont ete recoltes en periode estivale dans dix marais maritimes littoraux de l'atlantique francais destines a l'aquaculture semi-extensive de penaeus japonicus. Deux especes, alkmaria romijni et streblospio benedicti sont, en france, de signalisation nouvelle pour ces biotopes; un individu a ete rapporte au genre heteromastides (augener, 1914), non repertorie en europe, mais sa diagnose demande a etre confirmee. La distribution faunistique s'est averee etre geographiquement et temporellement fluctuante et liee, en particulier, aux activites anthropiques, a la predation des elevages, au confinement et a la qualite du sediment, ces deux dernieres caracteristiques permettant de mettre en evidence des affinites biocenotiques entre bassins d'une meme zone de marais. Les biomasses de macrofaune benthique ont varie de 4. 9 a 44. 8 g. M##2 de matiere organique seche.

Abstract:
A l’échelle de l’Atlantique Nord-Est, la Manche se situe à un carrefour biogéographique entre les provinces boréale et lusitanienne. Ainsi, de nombreuses espèces y sont en limite d’aire de distribution. L’objectif de cette thèse est d’évaluer les effets du changement climatique récent sur la distribution de la macrofaune benthique subtidale, peu étudiée à ce jour, en se basant sur la comparaison de données collectées à l’échelle de la Manche lors une période froide (i.e. années 1960-70) et lors d’une période chaude (i.e. 2012 et 2014) dans les sédiments grossiers circalittoraux. L’étude de la structure des assemblages inféodés à cet habitat a mis en évidence deux grandes communautés benthiques : la communauté des sédiments grossiers sablo-graveleux et celle des cailloutis et graviers. L’analyse de l’évolution des températures de fond au cours des 30 dernières années a montré l’hétérogénéité spatiale du réchauffement, variant de 0,1 à 0,5°C par décennie d’ouest en est. Ce réchauffement ne se s’est pas traduit par d’importants déplacements de l’aire de distribution des espèces mais par une forte diminution du nombre d’occurrences des espèces d’eaux froides et une forte augmentation de celui des espèces d’eaux chaudes. Le développement de modèles de distribution d’espèces a permis de déterminer l’importance relative des facteurs climatiques et édaphiques dans la distribution des invertébrés benthiques en Manche et d’apprécier l’aptitude des espèces à ajuster leur distribution à la hausse de températures. L’ensemble de ces résultats suggère que le changement climatique en cours pourrait entraîner une diminution de la biodiversité benthique aux limites d’aires de distribution, en particulier si la connectivité entre populations limite l’arrivée de nouveaux individus<br>In the North-East Atlantic, the English Channel constitutes a biogeographical transition zone between the Boreal and Lusitanian provinces. Thus, many species reach there their distribution range limits. The aim of this thesis is to assess the effects of recent climate change on the distribution of the subtidal benthic macrofauna, poorly studied to date, basing on the comparison of data collected during a cool period (i.e. 1960s-70s) and during a warm period (i.e. 2012 and 2014) in the circalittoral coarse sediments. Two large communities were highlighted in the study of the structure of the assemblages found in this habitat: the gravelly coarse sand community and the pebbles and gravels community. The analysis of the evolution of seabed temperature for the last 30 years showed the spatial heterogeneity of the warming, varying from 0.1 to 0.5°C per decade from West to East. This warming did not translate into large species distribution shifts but into a sharp decrease in the number of occurrences of cold-water species and a sharp increase in the number of occurrences of warm-water species. Development of species distribution models allowed to identify the relative importance of climatic and edaphic factors in the distribution of benthic invertebrates in the Channel and to assess the species’ ability to adjust their distribution to the rise in temperature. The whole results suggest that ongoing climate change could lead to a decrease in benthic biodiversity at range limits, especially where connection routes are lacking for new migrants

Abstract:
Les vasières intertidales sont des environnements complexes et changeants, qui abritent des invertébrés enfouis dans le sédiment (la macrofaune benthique) et sont visités de manière saisonnière par de grands migrateurs : les oiseaux limicoles. Ce travail de recherche s’intéresse aux relations proie-prédateur entre les oiseaux limicoles et leur ressource alimentaire : la macrofaune benthique. La thèse est articulée en 8 chapitres qui présentent des études à différentes échelles spatio-temporelles : des saisons à la décennie, et de la baie à la route migratoire. Ces études sont basées sur un échantillonnage régulier des vasières intertidales du Golfe de Gascogne (France) ainsi que d’échantillonnages en mer des Wadden (Pays-Bas) et au Banc d’Arguin (Mauritanie). Les données de macrofaune (qualité, taille, densité, biomasse) sont couplées aux données de comptages de leurs prédateurs ainsi qu’à leur comportement alimentaire (reconstruction du régime alimentaire d’après les isotopes, les fécès, la modélisation ou l’observation de vidéos). Ces huit études apportent un éclairage sur l’écologie de leurs interactions (en intégrant des variables environnementales telles que le temps d’inondation, la granulométrie, la température, la production primaire, ou encore la latitude). Une attention particulière est portée à la variabilité des proies et du comportement alimentaire de leurs prédateurs, dans l’espace et le temps. Des encarts viennent illustrer pour l’un les techniques de reconstruction du régime alimentaire, pour l’autre les défenses développées par les mollusques marins, ou encore la relation entre énergie à disposition et sélection du site pour les limicoles<br>Intertidal mudflats are complex ecosystems undergoing constant changes, home to infaunal invertebrates (benthic macrofauna), and migratory sites for particular birds : shorebirds. This research focuses on predator-prey interactions between shorebirds and their macrobenthic prey. The present thesis is composed of 8 chapters which illustrate different spatio-temporal scales : from seasons to the decade, and from the bay to the migratory flyway. These studies are based on regular benthic sampling of intertidal flats along the Bay of Biscay (France), as well as sampling data from the Dutch Wadden Sea and the Mauritanian Banc d’Arguin. Macrobenthic data (quality, sizes, densities, biomass) are linked with shorebird counts and data about their feeding behaviour (diet reconstruction from isotopes, faeces, modeling and video observations). These eight studies shed light on particular relationships between some prey and their predators, and the ecology of these interactions (including environmental variables such as inundation time, grain size, temperature, primary production, or even latitude). Particular attention is given to the variability of prey and predator behaviour in time and space. Inserts are included in between chapters to illustrate for instance different diet reconstruction techniques, anti-predation traits in marine molluscs, or relation between energy available and site selection in shorebirds

Abstract:
L’objectif général était d’évaluer la réponse du macrobenthos à la dynamique d’un herbier marin à Zostera noltii (colonisation, maturation, destruction, restauration), dans le Bassin d’Arcachon, une lagune du sud-ouest de la France. Quand l’herbier commence à se développer, la structure de la macrofaune diverge immédiatement entre habitats d’herbier et de sables nus, sans cependant que les indice biotiques testés (BENTIX, BOPA, AMBI) varient. De même, la population du bivalve dominant, la coque (Cerastoderma edule), souffre du développement de l’herbier. Sa communauté parasitaire (trématodes) est modifiée, sans que cela n’influe sur la dynamique des coques. A l’échelle du Bassin, le développement de l’herbier (considéré comme un signe de “bonne santé”) a été comparé à la santé de deux bivalves endogés dominants, la palourde japonaise (Ruditapes philippinarum) et la coque (C. edule), évaluée en termes de prévalence de maladie. Aucune corrélation n’existe entre le taux de recouvrement d’herbier et la prévalence de trois maladies (trématodiase, perkinsose, maladie du muscle marron). Entre 2002 et 2010, la surface d’herbier a diminué de 1/3. En termes de structure de communautés et d’espèces dominantes, peu de différences sont notées au sein de chaque année (entre les 12 stations) et entre années, indépendamment du déclin de l’herbier. Parmi les indicateurs biotiques, l’indice multivarié MISS est en adéquation avec la relative similarité de la structure de la macrofaune benthique entre les groupes discriminés par l’analyse MDS. En 2005, des activités de dragage dans le Bassin d’Arcachon ont abouti à l’enfouissement de 0,32 km2 d’herbier à Z. noltii. La structure du macrobenthos a été immédiatement modifiée sans retour à l’état initial sur les zones couvertes de sable. En revanche, le macrobenthos (endofaune) s’est rapidement rétabli dans les zones couvertes de vase alors que l’herbier n’a commencé à se développer qu’au bout de 5 ans après les travaux. Le dernier chapitre de cette thèse donne un bref aperçu des connaissances actuelles sur les herbiers vietnamiens et des possibles travaux scientifiques à mener<br>The overall objective was to assess macrobenthos response to marine Zostera noltii seagrass dynamics (colonization, maturation, destruction, restoration), in Arcachon Bay, a French Southwestern lagoon.When seagrass starts to develop, the structure of macrofauna community immediately diverges between sand and seagrass habitats, without however modifying tested biotic indices (BENTIX, BOPA, AMBI). As well, population of the dominant bivalve, the cockle (Cerastoderma edule), suffers from seagrass development. Their parasite (trematode) community are impacted, but not sufficiently to explain cockle deficit in seagrass.At the scale of the Bay, seagrass development (considered as a sign of “good health”) is compared to the fitness of the two dominant infaunal bivalves, the Manila clam (Ruditapes philippinarum) and the cockle (Cerastoderma edule), measured in terms of disease prevalence. There was no correlation among seagrass cover rate and the prevalence of three diseases: trematodiosis, perkinsosis and Brown Muscle Disease.Between 2002 and 2010, seagrass cover decreased by 1/3. When looking at community structure and dominant species, there were moderate differences within (among 12 stations) and among years, independently of seagrass decline. Among biotic indicators, multivariate index MISS was in adequation with the relative similarity of macrofauna structure among groups discriminated by MISS analysis.In 2005, dredging activities in Arcachon Bay led in burying 0.32 km2 of Z. noltii. Macrobenthos structure was immediately modified and did not recover in places buried by sand. Conversely, macrobenthos (infauna) recovered rapidly in areas cover by mud, while seagrass began to develop again five years after work. The last chapter of the thesis provides a brief insight of the seagrass in Vietnam, the actual knowledge and what could be investigated

Abstract:
Discriminer l'influence des activités humaines de celle des processus naturels sur les changements environnementaux récents est un enjeu scientifique important. Dans ce but, les mollusques et les foraminifères fossiles des Pertuis Charentais (ouest de la France) ainsi que les sédiments déposés pendant l'Holocène dont ils sont issus ont été étudiés. L'objet d'étude central est un drapage vaseux qui constitue une grande partie du comblement sédimentaire terminal des Pertuis. Les résultats obtenus montrent qu'il est composé de sédiments fins d'origine continentale déposés à partir de 1400 AD. Il est la conséquence d'une augmentation de l'érosion des sols, favorisée par la déforestation entreprise au Moyen-Age. Le taux de sédimentation de cette vase a augmenté brutalement, suite à une période d'augmentation des précipitations hivernales à la fin du Petit Age Glaciaire qui a accéléré l'érosion des sols sur ces territoires fragilisés car déforestés. Le dépôt brutal de sédiments fins dans les Pertuis Charentais a eu peu de répercussions sur les communautés de mollusques benthiques, excepté l'extinction locale du bivalve \textit{Lepton squamosum} de la baie de Marennes-Oléron. En revanche, l'augmentation des apports sédimentaires a été à l'origine d'une succession écologique au sein des communautés de foraminifères (résistance - perturbation - adaptation). Les résultats obtenus démontrent comment des milieux perturbés par les activités humaines deviennent plus sensibles aux changements climatiques. Ils soulignent aussi le potentiel de la paléoécologie dans la compréhension des changements environnementaux récents dans les zones côtières à une échelle millénaire à séculaire.

Abstract:
Ce travail de recherche s'inscrit dans le contexte de contamination des sols par les pesticides utilisés en agriculture. Cette problématique est un enjeu majeur et actuel puisque l'étendue spatio-temporelle de la contamination est méconnue. Il s'agit donc ici de mieux comprendre la dynamique des herbicides dans les écosystèmes pour mieux en évaluer les risques a priori et plus précisément de savoir dans quelle mesure et par quels mécanismes les organismes édaphiques régulent leurs dynamiques physiques et chimiques. Deux hypothèses alternatives ont été testées avec la molécule herbicide modèle, l'atrazine : i) la macrofaune lombricienne contribue à la dégradation partielle ou totale de l'atrazine en stimulant l'activité de la microflore dégradante et ii) la macrofaune lombricienne favorise la liaison de l'atrazine avec les complexes argilo-humiques du sol, au sein de microsites favorisant la rétention et la rémanence de l'herbicide. Des expérimentations en présence et en absence de Lumbricus terrestris et Aporrectodea caliginosa ont été effectuées à différentes échelles spatiales et temporelles, avec de l'atrazine-14C. S'agissant du rôle de la macrofaune lombricienne, les résultats expérimentaux obtenus ont montré que : • l'ingestion du sol par la macrofaune lombricienne favorise l'adsorption de l'atrazine et conduit à un redistribution des quantités d'atrazine et de ses résidus liés dans les biostructures (avec dans l'ordre : parois de galeries - déjections excrétées dans les galeries – déjections en surface ou turricules – contenus intestinaux ou endentères) par rapport au sol non ingéré et due à un enrichissement en carbone organique conjugué à une plus forte microporosité. • inversement, la minéralisation de l'atrazine n'est pas stimulée voire ralentie en présence de vers. C'est le passage du sol dans le tractus digestif, au cours duquel la structuration des communautés bactériennes initiales du sol est modifiée, qui limite la dégradation totale de l'atrazine par voie microbienne. • une diminution significative du potentiel génétique dégradant (gènes atz) consécutive à l'ingestion a été mise en évidence, suggérant une forte déplétion de la population bactérienne dégradante Pseudomonas sp. ADP. De ces résultats originaux, il est conclu que l'activité de la macrofaune lombricienne dans les sols tendrait à augmenter le temps de résidence du polluant et donc sa rémanence mais s'opposerait à son élimination par biodégradation naturelle par les bactéries.

Mes objectifs consistaient à : (1) fournir une description de l'état actuel des communautés de la macrofaune benthique du golfe du Lion et à étudier leur variations temporelles entre 1998 et 2010 à partir de 91 stations, (2) tester le contrôle de la macrofaune par les variables climatiques à partir du suivi de 4 stations pendant 10 ans en baie de Banyuls-sur-Mer, (3) évaluer l’impact des apports du Rhône sur la macrofaune à partir de 5 stations échantillonnées dans le panache de dilution à 4 périodes hydrologiques différentes, et (4) actualiser le statut de qualité écologique des habitats benthiques du golfe. Mes résultats ont montré la conservation des communautés entre 1998 et 2010,confirmé l’influence de la NAO et du Rhône sur la composition des communautés benthiques de l’ensemble du golfe. Ils ont aussi confirmé le contrôle des descripteurs de la macrofaune par les oscillations climatiques, en particulier par la WeMO qui semble influencer le plus la macrofaune surtout en hiver. Les stations les plus impactées par les variations de débit du Rhône se situent à proximité immédiate de son embouchure. Les communautés benthiques y sont négativement affectées en périodes de crues et positivement affectées en période d’étiage estival. J'ai enfin mis à jour les niveaux de sensibilité/tolérances des espèces méditerranéennes, confirmer l’existence de disparités importantes entre les résultats dérivés de l’utilisation d’indices biotiques différents et montrer que les indices testés indiquent tous une tendance générale à la stabilité<br>My main aims consisted in: (1) assessing the present state and recent (1998-2010)changes in benthic macrofauna composition of the Gulf of Lions soft-bottom communities through the long term comparison of 91 stations; (2) testing the current paradigm regarding the control of those communities by climatic parameters through a 10-year monitoring of 4 stations located in the Bay of Banyuls-sur-Mer; (3) assessing the influence of Rhône River inputs on the composition of benthic macrofauna through the sampling, of 5 stations , under 4 hydrological regimes; and (4) updating the ecological quality status of Gulf of Lions benthic habitats. My results have shown the persistence ofthe same 3 communities between 1998 and 2010, the strong influence of both the NAO and the Rhône River on benthic macrofauna composition in the whole Gulf. They also showed a control of benthic macrofauna by climatic oscillations with the WeMO contributing most especially during wintert ime. Moreover, the stations most impacted by Rhône River inputs were located close to its mouth. They are negatively affected during floods and positively affected during dry periods. Lastly, Ihave updated the sensitivity/tolerance levels of Mediterranean species and confirmed the existence of major discrepancies in the results derived from different biotic indices used, although all tested indices indicated an overall stability in the ecological quality status of benthic habitats between 1998 and 2010

Abstract:
The effect of the addition of detrital subsidy on the winter wheat ecosystem was evaluated. Already during the first growing season after the addition, detrital subsidy led to an increase in yield by 17% and twofold population growth of soil saprophagous macrofauna. A significant correlation (r = 0.39) between abundance of Collembola species P. notabilis and Fusarium species in soil was revealed.

Abstract:
Mass bleaching and subsequent mortality of scleractinian corals in response to elevated seawater temperatures has been considered as one of the most impacts of global climate change. Three extensive coral bleaching events in the Andaman Sea were reported, in the years 1991, 1995 and 2010. Studies on survival of coral colonies, coral recruitment and community structure of coral reef associated macrofauna would predict the trends for coral recovery from the impacts of coral bleaching events. The present study aimed to examine the status of coral communities, density of coral recruits and coral reef associated macrofauna at nearshore coral reefs in Phangnga Province, the Andaman Sea following the 2010 coral bleaching event. The dead coral cover was high (&gt;50%) while the live coral cover was in the range of 13-21%. There was high diversity of coral recruits on natural substrates. The average densities of macrobenthic fauna varied from 1.9 to 2.6 individuals.m-2, with significant differences among study sites. The dominant macrobenthic species were a soft coral (Lobophytum sp.), a sea star (Linckia laevigata) and a sea urchin (Echinostrephus molaris). Coral recovery at these coral reefs would be possible but local anthropogenic stressors must be overwhelmingly reduced in order to enhance coral reef resilience. The long-term monitoring programs in the Andaman Sea are required for decision makers to support their adaptive management approaches.
