Der volle Inhalt der QuelleBody size is a powerful trait to describe how organisms interact with their biotic and abiotic environments. Size distribution in food webs can be formalized by a negative linear relationship between organism size and abundance. This relationship, usually referred as the "size spectrum", is commonly used in marine ecosystems to assess the impacts of commercial fisheries on food webs properties. In this work, our aim was to develop this size-based approach on communities to quantify the effects of global changes on the functioning of lacustrine ecosystems. In a first chapter, we investigated the spatial variation of the fish size spectrum in natural and reservoir lakes on a national scale using various biomonitoring surveys. While bioindicators were significatively affected by eutrophication and biological invasions, our findings highlighted the added value of using the size spectrum to highlight the impacts of habitat alterations. In a second chapter, we quantified the temporal stability of these communities in response to changes in the intensity of global change drivers. Biological invasion had no influence on the fish size spectrum dynamic, but we observed that increased water temperature, as well as increased nutrient loading could be linked to short-term changes in size spectra. In the third chapter, we assessed the relationship between size spectrum slope and the trophic structure of fish communities. Using stable isotope analysis, we showed that a low predator-prey mass ratio, suggesting to higher trophic transfer efficiency, induced flatter size spectrum slopes (higher abundance of large fishes). However, the presence of non-native species disrupted this relationship and reduced the potential for using the size spectrum to reflect energy flux in food webs. In the fourth chapter, our goal was to experimentally identify how changes in the size spectrum reflect changes in ecosystem functioning (e.g. productivity or metabolism). Results demonstrated that size spectrum can be linked to primary and secondary production through bottom-up processes, and changes in the intensity of trophic cascades through top-down processes. Taken together, these results demonstrate the relevance of using size structure to quantify anthropogenic impacts on lacustrine communities and the potential consequences on ecosystem functioning, with possible applications in biomonitoring programs at ecosystem level

Der volle Inhalt der QuelleThis work has tested the assumption of "convergence" according to which communities subjected to the same environmental constraints converge towards a common structure. We chose as a model, fishes of the temperate and tropical streams of four zoogeographical areas: Europe (France), North America (USA), South America (Bolivia) and Africa (Gabon). Hence, ecomorphologic characteristics and trophic structure of fish communities were compared at local, regional and intercontinental scales between various sites and various streams. The results show that local communities’ organization depends on the combination of both local and regional and abiotic and biotic processes, relying on a historical and biogeographical context. These results could be useful for the decision makers to implement efficient conservation and management plans of the lotic systems

Der volle Inhalt der QuelleWhat are the ecological evolutionary mechanisms governing species interactions? I addressed this issue considering the interaction between the parasite Tracheliastes polycolpus and several of its cyprinid hosts. First, I highlighted the role of the environment at a very fine spatial scale (few hundred meters) on the encountering rate between this parasite and its hosts. At larger spatial scale (France) I illustrated the limiting role of resistance of host populations on the distribution of T. polycolpus. I further showed that T. polycolpus manages to infect different host species by relying on a plastic expression of its genes. Finally, I showed that host bacterial communities change after T. polycolpus infection in a co-infection dynamics with the parasite. Through the deployment of various and complementary approaches, it appears that both environmental factors, factors related to the host, to the parasite and to their associated bacterial communities contribute to the success of an intimate interaction such as parasitism

Der volle Inhalt der QuelleThe publication of the handbook of European freshwater fishes by Kottelat and Freyhof in 2007, in which the authors list 16 additional native species in France, set off e taxonomical revision of French and European ichtyofauna. The objective of the present thesis is to revise 5 genera of freshwater fisches of France in an integrative taxonomy framework using morphological, molecular and ecological data : Squalius (chub), Phoxinus (minnow), Gobio (gudgeon), Esox (pike) et gasterosteus (three-spined stickleback). More than 1700 specimens were collected in 283 locations in France, studied and analyzed morphologically, before integration in the MNHN collections. More than 460 specimens were studied genetically, including complete mitogenome sequencing for a subset. Also we compared secondary sexual ornamentation of minnows among basins as well as analysis of the niches occupied by the different gudgeon species. The results confirm the presence of two chub species in France S. Cephalus and S. Laietanus. The use of molecular data invalisates G. Gymnurus, so there is a single species of three-spined stickleback G. Aculeatus. The study of collection materials shows the presence of three pike species : E. Lucius, E. Cisalpinus and a previously undetected new species E. Aquitanicus. Secondary sexual ornamentation corroborated by sequence data discriminates 6 minnow species, including P. Phoxinus, P. Bigerri; P. Septimaniae, P. Marsilii which would be valid, as well as two new species. The use of morphological, molecular and ecological data support 3 out of the 4 gudgeon species (G. Gobio, G. Lozanoi et G. Occitaniae; G. Alverniae would be a junior synonym of G. Occitaniae). The new taxonomical data highlight the gaps in our knowledge of the French freshwater fauna. It oepns new perspectives and opportunities of research in numerous fields of biology. However this kind of in-depth study should be applied to all French taxonomic groups

Der volle Inhalt der QuelleThe purpose of these experimental studies was to assess the variability of quality in farmed and wild Eurasian perch (Perca fluviatilis) and its determinism. Quality is divided into three components: organoleptical (morphology and color), technological (filleting yield, morpho-anatomical index) and nutritional (total lipids content and fatty acids composition in fillet). The quality of perch shows variability according to the geographic origin, season and rearing systems. Farmed perch differ from wild counterparts by technological and nutritional components: perivisceral fat content and n-6 poly-unsaturated fatty acids (PUFA) increase with the intensification level of farmed system, whereas n-3 PUFA decrease. Thus, there is not only one perch quality but rather many perch qualities. Consequently, hypothesis have been formulated about factors responsible for the variability of quality and then tested. Two populations of wild perch from different geographic origin were reared in laboratory from eggs stage, in the same environmental and trophic conditions. The results show that only nutritional component displays differences between the two populations. Thus, phenotypical expression of the quality is under control of both origin (genotype) and environmental factors. Among these factors, 4 factors with 2 modalities were tested in 8 experimental units using a fractional factorial design: dietary lipids origin, feeding rate, density and domestication. Domestication and dietary lipids origin (simple factor or interaction) were found as the main factors of the determinism of perch quality

Der volle Inhalt der QuelleParasite species with global distribution and complex life cycle offer a rare opportunity to study mechanisms of speciation and evolution. Ligula intestinalis (L. ) (Cestoda, Diphyllobothriidea) has a widespread distribution and a life cycle with several hosts Available records indicate that the host spectra used by this species is not uniform across the investigated populations and show differences in the pathology between sympatric cyprinid species. Furthermore, complication of L. Intestinalis picture stems from the indication that this species may be paraphyletic with the species Ligula colymbi and Digramma interrupta. The aim of this study was to understand the origin of eco-biological differences and phylogenetic discrepancies and to test the hypothesis of the existence of several strains/species. . For this purpose, phylogeny and genetic structure have been analyzed for Ligula plerocercoids native to different host species and geographic regions at a global scale. Data based on genomic sequences and hypervariable markers show different evolutionary patterns: At a local scale, a flat genetic structure was found and is most likely due to bird migration preventing the creation of different genetic strains/species. In contrast, at a global scale, genetically distant and well separated clusters are present, indicating a conspicuous correspondence between genetics and geography. Beside geography, obvious host-specific-based structures are found. Ligula specimens identified as L. Colymbi are partitioned in separate clades of L. Intestinalis thus questions the reliability of species identification primarily based on definitive host species when morphological characters are inconclusive. Samples of Digramma show a clear differentiation from the analysed Ligula specimens. However, their monophyletic clade appears within Ligula specimens indicating that D. Interrupta may well represent a valid species of the genus Ligula rather than of Digramma

Der volle Inhalt der QuelleClimate change has been a subject of great interest across the past few years but its influence on population dynamics has seldom been considered. In this thesis, we demonstrate that climatic factors and in particular water temperatures have an influence on population dynamics of several freshwater fish species found in French rivers. Although common mechanisms acting at large spatial scales have been identified for the different species, considerable variations among populations have been revealed due to spatial heterogeneity of environmental conditions. Intrinsic characteristics of species appeared as important determinants of interspecific differences in population dynamics, contrary to their evolutionary history. Our results could be used to set up management conservation planning to limit the consequences of climate warming on freshwater fish species
Cilleros, Kévin. „Diversité et règles d'assemblage des communautés de poissons d'eau douce de Guyane“. Thesis, Toulouse 3, 2017. http://www.theses.fr/2017TOU30287/document.
Der volle Inhalt der QuelleTropical ecosystems, especially Amazonian ecosystems, host a great diversity of terrestrial and aquatic organisms. However, the causes and the processes behind this high diversity for freshwater fish assemblages are little known, but their identification will be an asset in the assessment of anthropogenic impacts that are increasing in these regions. We studied the processes that shape the diversity and the structure of freshwater fish assemblages of non-impacted streams and rivers located in French Guiana. Within-assemblage diversity increased along an upstream/downstream gradient and was higher in sites where the habitat was diversified. Species identity changed along this gradient, which created zones along the stream. Spatial relationships between assemblages and their isolation also greatly impacted species assemblages. Using information about species traits (functional diversity) and their phylogenetic relationships (phylogenetic diversity), we showed that within-assemblage diversity was not influenced by the environment or by species interactions. We also confirmed that dispersal limitation, linked with the past history of drainage basins, had a strong effect on assemblage structure in both streams and in rivers. Future investigations on the processes structuring fish assemblages will need to acquire more exhaustive biological data, and therefore to develop an efficient, and non-destructive sampling method. To this aim, we evaluated the efficiency of environmental metabarcoding applied to aquatic assemblages (the molecular identification of species present from a water sample) and compared it to traditional sampling methods. Currently, metabarcoding gives complementary information to traditional sampling. It thus needs developments and further tests to increase its efficiency and allow its use for assembly processes studies. Pursuing the formalization of a conceptual framework to investigate assembly rules together with the development of an efficient fish sampling protocol are now needed to better understand the structure of tropical fish assemblages. Those theoretical and practical developments will contribute to better evaluate anthropogenic disturbances on aquatic ecosystems
