Full textThis thesis provides a complete taxonomic review of South African hermatypic Scleractinian reef corals, a description of coral communities on northern Natal coral reefs, experiments isolating the influence of the most important abiotic factors forcing these communities and finally management suggestions for the marine reserves within which these reefs are situated, based on the results of the ecological investigation. The taxonomic part reviews the entire hermatypic scleractinian coral fauna of South Africa and Southern Mozambique, including also material from the Atoll Bassas da India in the Mozambique channel. The study of coral communities on Northern Natal coral reefs revealed major differences in the nature of the reefs and the community structure of the reef corals from typical coral reefs in the Inda-Pacific. The study lead to the assumption that wave-action and sedimentation are the most important abiotic factors influencing these coral communities. These hypotheses were experimentally tested in the field and in the laboratory, using indicator species for specific community types, as identified in the community study. Testing fragment survival of the hard coral Acropora austera confirmed the assumption that wave action is an important factor shaping coral communities by only allowing this species to dominate in depths greater than 18m. Four hard- and five soft coral species were used to quantify the effects of sedimentation on the coral communities. It was demonstrated that long-term sedimentation had greater influence on soft corals than on hard corals, leading to tissue necroses and local bleaching. These experiments confirmed the assumption that sedimentation is a major forcing factor on South African coral communities. The final part of thesis provides management options for the St. Lucia and Maputaland Marine Reserves focussing on conservation of the coral communities. The findings obtained in the ecological investigation allowed to identify which activities in the reserves have to be controlled in order to minimize damage to the coral communities by park visitors.

Full textL'environnement marin présente moins de barrières au flux génétique que ses équivalents terrestres et d'eau douce. De plus, les phases planctoniques larvaires prévalences chez les espèces marines peuvent potentiellement maintenir un flux génétique a travers de grandes distances géographiques. Ces observations soulèvent deux questions fondamentales. Comment se développent de nouvelles espèces dans le milieu marin? Considérant le flux génétique potentiellement important, il demeure incertain dans quelle mesure la spéciation allopatrique peut expliquer la grande diversité observée dans le milieu marin, si la speciation opère également en présence de "flux génétique, et si oui par quels mécanismes. Quelle distance parcourent les phases larvaires planctoniques avec les courants marins? La structure génétique généralement faible parmi les populations marines suggère une dispersion extensive, mais les larves planctoniques sont notoirement difficiles a suivre en raison de leur petite taille et par conséquent I’ échelle spatiale de la dispersion marine échappe encore largement aux écologues.lci, je considère les poissons de récifs coralliens brillamment colores du genre HypopJectrus (Serranidae) comme systeme modèle pour aborder ces deux questions. Je démontre comment la speciation écologique avec flux génétique peut opérer dans ce système par I’ effet plëiotropique du patron de coloration, qui semble être impliquée dans le mimétisme ainsi que dans le choix d'un partenaire sexuel. Je montre que des processus locaux opèrent a I’ échelle des Caraïbes dans ce systeme, ce qui suggère une dispersion limitée. Je teste et confirme cette hypothèse en reportant de I’ isolement génétique par la distance chez HypopJectrus puella des échelles spatiales allant de 175 a3,200 km. Afin d'estimer la distance de dispersion moyenne je complémente les données génétiques avec des relèves de densités de population couvrant

Full textFish spawning aggregation (FSA) sites are areas where repeated concentration of conspecific fish gathers for the purpose of spawning. Despite of their importance in the reproduction of many coral reef fishes, few FSA sites are actively managed. The aim of this study, conducted in the Seychelles, was to improve general understanding on the ecology of FSA sites to facilitate their management. It focuses on both the individuals that aggregate at FSA sites to spawn and those that are resident at FSA sites. Acoustic telemetry and underwater visual census were used to study three species that form spawning aggregations (spinefoot shoemaker (Siganus sutor), Camouflage grouper (Epinephelus polyphekadion) and Brown-marbled grouper (E. fuscoguttatus)) and the resident fish assemblages at FSA sites. Acoustic detections found individual S. sutor to have high fidelity to individual FSA sites and to show significant periodicity with the full moon period in the timing of their arrival and departure from FSA sites. Conversely, spawning aggregations of E. fuscoguttatus and E. polyphekadion overlapped spatially and temporally, with strong periodicity for spawning aggregation to form with the new moon period. The formation of E. fuscoguttatus and E. polyphekadion FSAs caused complex changes in the fish assemblage that is resident at the FSA site. The effect of lunar phase on the resident fish assemblages at S. sutor FSA sites appeared to be scale-dependent, having greater impact at the larger than the smaller FSA site. Information on the spatial and temporal dynamics of aggregating and resident fish species is used to propose management actions to improve the protection of FSA sites

Full textDans les populations qui sont soumises à une forte mortalité locale, l'immigration à court terme - via la relocalisation du domaine vital - a d'importantes implications pour la dynamique des métapopulations, l'exploitation soutenable des ressources, la lutte contre les espèces introduites et invasives et la conservation. Malgré son importance, il n'existe pas de théorie prédisant l'immigration dans une zone exploitée à partir d'une zone protégée adjacente. Il existe aussi très peu d'information sur les facteurs influençant l'intensité de l'immigration. J'ai développé un modèle d'immigration compensatoire afin de prédire les effets d'une réduction locale de la densité sur l'immigration en utilisant des scénarios hypothétiques variant dans l'inclusion de facteurs limitant. Le modèle prédit que l'immigration peut contribuer à la récolte totale et à la récupération des populations exploitées et peut affecter la démographie dans la zone protégée. L'immigration et la récolte totale sont reliées de façon complexe et non-linéaire avec l'exploitation cumulative en relation avec la taille de l'aire protégée, le taux initial de remplacement des individus récoltés, la mobilité et les interactions comportementales. Des expériences sur le terrain m'ont permis de valider le modèle et d'estimer l'influence relative de facteurs limitant à l'immigration (i.e. la taille de la population dans la zone protégée, la qualité de l'habitat relative et la connectivité fonctionnelle entre la zone exploitée et la zone protégée). J'ai utilisé la demoiselle noire (Stegastes dienaceus) et la demoiselle brune (S. adustus) et leur habitat comme système modèle. J'ai examiné en premier lieu la connectivité fonctionnelle en relocalisant des demoiselles afin d'investiguer quelles caractéristiques de l'habitat ou caractéristiques sociales peuvent représenter une barrière au mouvement lors du comportement de retour au territoire (ang. « homing »). Les petites étendues de sable constituent une barrière partielle au mouvement mais l'effet de la taille de l'étendue de sable varie en fonction de la configuration des récifs. Les poissons minimisent les mouvements au-dessus des territoires de leur conspécifiques. J'ai également entrepris une réduction expérimentale, incrémentée et répliquée de populations de demoiselles qui a servi à examiner les mécanismes régissant la relocalisation du domaine vital à l'échelle du territoire et l'immigration à l'échelle du paysage. À l'échelle du territoire, la probabilité qu'un territoire soit recolonisé diminue avec une réduction de la densité. Les territoires ont tendance à être recolonisés par des individus de la même espèce, du même sexe et de taille comparable à celle de l'occupant original. Les territoires occupés initialement par les individus les plus gros ont une probabilité plus forte d'être recolonisés. À l'échelle du paysage, les modèles qui assument un remplacement constant mais partiel des individus récoltés ont un meilleur support statistique que les modèles incluant soit un remplacement incomplet ou une absence de remplacement. Dans plusieurs sites où la densité à été manipulée, le modèle ayant le meilleur support statistique incluait également des paramètres modélisant de la densité dépendance (i.e. changement de direction et d'intensité en relation avec la récolte cumulative). La récolte totale et la proportion des individus récoltés qui étaient remplacés par les immigrants étaient corrélées avec l'effet combiné de la qualité de l'habitat et de la connectivité fonctionnelle. En conclusion, ma thèse propose et test un modèle d'immigration compensatoire prédisant l'immigration d'individus habitant les aires protégées vers les zones exploitées. Ce modèle considère la variation de la mobilité, la qualité de l'habitat, la connectivité fonctionnelle et les interactions comportementales afin de prédire les effets de l'immigration dans un contexte d'exploitation soutenable et de conservation à l'échelle de la métapopulation.
