Full textThe success of revegetation or ecological restauration highly depends on our knowledge of mechanisms underlying changes in composition and structure of the vegetation along the ecological succession. Natural or human-induced disturbances of varying intensity and frequency often occur simultaneously to influence vegetation temporal dynamics. However, the influence of a recurrent disturbance combined with ecological changes along plant succession remains poorly documented.Plant communities growing on road slopes are particularly appropriate to study this issue. Construction work and management history are well documented, so that the age of the vegetation and its disturbance regime by mowing can be precisely informed. Thus, road slopes plant communities represent an in situ quasi-experimental framework particularly adapted to study processes affecting community assembly along the ecological succession under the influence of a recurrent disturbance.The principal objective of this study is to characterise the successional dynamic initiated after road slope construction in the Mediterranean area, and to identify the ecological processes and environmental factors influencing this dynamic. We particularly focused on the influence of recurrent mowing on this dynamic.We studied the floristic composition and the diversity of functional traits (mainly leaf traits and flowering phenology traits) in a 70-year long chronosequence of French Mediterranean (Hérault, France) road slopes, each including both mown and unmown vegetation.The analysis of taxonomical variations between road slopes plant communities reveals a large species turnover along the ecological succession. This floristic turnover relates with functional changes within communities. These functional changes are structured by environmental filters influencing flowering synchrony within communities on one hand, and the diversity of a combination of functional traits between communities of similar age on the other hand. These environmental filters changing along the succession relate with changing soil parameters and increasing spatial heterogeneity of light and temperature conditions with canopy closure.Mowing alters floristic and functional trajectories along the succession, notably through the decrease of speed in resource-use strategy changes along the succession in mown communities compared to unmown communities. In addition, this recurrent disturbance increases taxonomic and functional diversity within communities, while it decreases taxonomic and functional turnover between communities of the same age. Finally, mowing acts as an additional environmental filter on community assembly along the succession and homogenises vegetation between communities of the same age.The conclusions of this study provide basic knowledge in ecology. It also has implications for the management of road slopes plant communities in the perspective of their revegetation after construction work. Our conclusions suggest, amongst others, that combining mown and unmown vegetation could provide habitats for a higher diversity of associated fauna. In addition, it would allow vegetation to be pleasant to road users, while still ensuring a good visibility for road safety

Full textMany species of autotrophic dinoflagellates can be parasitized by multiple eukaryotic parasitoids. These parasitoids have a specific life cycle resulting in the death of the host and the release of hundreds of zoospores that can infect a new host. Several studies have demonstrated their potential to control the host population in a few days as well as their great diversity and suggests a very complex dynamics of infection in this kind of environment. The objective of this thesis is to understand the parasitoid-dinoflagellates infection dynamics in a highly mixed estuary and a better understanding of the different interactions taking place within this system. To address this problem, we used the modeling approach (IBM). This approach has enabled to show that the hosts excystment process, also used by the parasites to survive the winter, helps to explain the persistence of the system. It has also demonstrated the potential influence of different types of parasitoid on the dynamics infection and succession of dinoflagellates species, with increased diversity of the host population in the presence of specialists and decreased with generalists. The estimation improvement of the parameter used to calculate the rate of encounter between hosts and parasites with experimental and numerical methods was also attempted. The results showed a significant change in this parameter depending on behavior and the need to take it into account for a better parameterization

Full textAfter a short presentation, of the physical geography of Upper-Normandy, where we can find more widely shown unpublished climatic datas, we describe all the ecologic factors which govern the aquatic and amphibious ecosystems of this area : ponds, watercourses, pool, alluvial gravel-pits, canals, dykes, marshes, moorlands. Then we examine how the notion of ecological niche, of ecocomplex, of vegetal sequencies could be applied, to these environments. From a pattern extracted from 300 plant distribution maps drawn for this research, a chorologic study founded, for the major part, on climatic datas shows a close correlation between the distribution of some species with peculiar repartition and the setting up of 3 contrasted climatic regions : a wide zone with an oceanic regime, several areas marked by a more or less strong continentality, an important zone penetrated by south influences. The phytosociologic study is based on a previous reflexion in order to restore the classical approach of aquatic and amphibious environments. The whole "stucturalist" knowledge is analysed : morphological structures and adaptation to the environment, the structure of communities in space and time, the structures in relation with the partition of the ecological niche. From the notion of adaptation which is very bound with aquatic communities liable to change under numerous forms, we suggest the notion of "waiting sociations". This notion enables us, more especially, to better understand the place occupied by some phytocenoses in the ecocomplex and to introduce the synsystem in a more natural way. The we study, with 160 associations, from Lemnetea to Alnetea, the application of these new concepts and a revision of the customary classifications, more especially for Potametea. Finally, to organize the protection of aquatic environment, solutions of ecologic management oriented on the control of flood are purposed. Those solutions are illustrated by experiments conducted in Upper-Normandy for ten years

Full textL’environnement lumineux de l’Océan Arctique est unique en raison d’interactions complexes entre la lumière et le couvert de glace de mer enneigé, et les oscillations de photopériodes extrêmes. Le succès des organismes photosynthétiques arctiques suggère donc des mécanismes de régulation flexibles qui permettent la survie lors de longues périodes d’obscurités, la capture de photons dans la pénombre sous la glace et la photoprotection rapide lors d’éclairements excessifs soudains. Les diatomées sont les producteurs primaires arctiques principaux. Elles exploitent le continuum de niches lumineuses induit par la transformation saisonnière de leur habitat au cours d’une succession de formes de vie sympagiques (glace) et planctoniques (eau). Lorsque la photosynthèse sature, les diatomées dissipent l’énergie lumineuse excessive en chaleur via le quenching non-photochimique (NPQ), principalement contrôlé par l’action du cycle des pigments xanthophylles (XC). Généralement, chez les diatomées, l’opération de ces mécanismes de photoprotection est finement adaptée à leur niche lumineuse. Cependant, peu d’études se sont intéressées aux souches arctiques, malgré les profonds contrastes de niches lumineuses qu’elles surmontent (glace, sous la glace, eaux de fontes, eaux libres). Ce manque de données entrave nos capacités à anticiper l’impact de l’intensification de l’environnement lumineux de l’océan Arctique, causée par la réduction de la superficie et de l’épaisseur du couvert neige-glace, sur l’intégrité écosystémique. Nous avons étudié les réponses à la lumière de cinq espèces de diatomées arctiques représentatives des différentes phases et habitats de leur succession saisonnière. Les espèces sympagiques ont exprimé une stratégie photoadaptative survivaliste, caractérisée par une croissance saturée à faible éclairement et un fort NPQ longuement maintenu à l’obscurité. Les espèces planctoniques ont montré une plus grande flexibilité d’exploitation de la lumière et une importante photoprotection activée par des éclairements intense et l’obscurité prolongée. Ces stratégies photoadaptatives divergentes gouverneront probablement des réponses hétérogènes à l’intensification de l’environnement lumineux arctique.
Over their highly productive seasonal succession, Arctic diatoms occupy shifting habitats and contrasted light climates defined by snow/ice cover dynamics and extreme photoperiod variations. These unique light environment features suggest Arctic diatoms are well adapted to survive prolonged darkness periods, exploit minimal light in snow-covered sea-ice and overcome spontaneous excessive, and potentially harmful, light exposures. Diatoms mitigate photooxidative damages by dissipating oversaturating light energy as heat via the non-photochemical quenching (NPQ), mainly regulated by the xanthophyll cycle (XC). How heterogeneous light niches influence Arctic diatoms photoadaptative traits remains largely unknown and a crucial missing link to apprehend Arctic Ocean’s response to shrinking sea-ice and increasing illumination. To address this question, we selected five Arctic diatoms species harbouring diverse life traits and representative of distinct phases across the seasonal light niche continuum: from snow-covered dimly lit bottom sea-ice to summer stratified waters. To access how Arctic diatoms cope with a heterogeneous light environment, we studied their acclimation to two light intensities and subsequent darkness incubations, and parametrized NPQ-XC induction upon light shifts. Our results highlight the sea-ice cover as a strong selective force shaping Arctic diatoms photoadaptative strategies. Ice-related species exhibited a survivalist photoadaptive strategy with growth saturating at low irradiance and strong photoprotective capabilities sustained even in darkness. Open-water species photophysiology was more dynamic, expressing flexible light utilisation capacities and great photoprotection capacities triggered by high light and darkness. Ice-edge species showed strong adaptation to light fluctuations and dark physiology fine-tuned depending upon light history. We argue that diverging photoadaptative strategies foster Arctic diatom success in their respective seasonal niches and will likely drive uneven responses to a transforming Arctic Ocean.
