Full textAlexandrium minutum is a dinoflagellate producing recurrent toxic blooms along the French Atlantic coast. Originally from the Mediterranean, this species has gradually invaded the European coasts. In this study we examined the processes that may affect population genetic diversity of A. Minutum. We made crossing experiments to determine its reproductive system. Then we used molecular tools to determine the importance of sexual reproduction in natural populations. Finally, we studied the genetic variability of annual blooms for two consecutive years in Penzé and Rance estuaries. Crossing experiments showed that gametes recognition in this species is not a bipolar system but involves different mating types. Using microsatellite markers, we found that blooms have a high genetic and genotypic diversity suggesting that clonal reproduction is not a dominant process during bloom period. The spatio-temporal genetic analyses showed significant differentiation at both spatial and temporal scales and indicates a restricted gene flow between the two sites. The genetic differentiation between estuaries could also be closely linked to the life history traits. Indeed, the rapid development of blooms in a new site, followed by the formation of a large number of cysts accumulated in estuaries could be a particular system characterized by high genetic buffer and limiting arrival of immigrants by competition. Finally, our results suggest that the toxic blooms observed in Rance, in the Morlaix Bay and Brest estuaries correspond to different introductions processes

Full textThis study focuses on the spatio-temporal varibility of reproduction in silver fir (Abies alba), in its French rear edge populations in the Mont Ventoux and Lure mountain. Usually, marginal populations contrast from core populations with lower and more variable densities. In our populations of firs, we found that lower densitiy leads to higher selfing rates through a mass-action law at both population and individual levels. As a consequence, germinative abilities were lower for seeds from lower density populations, mainly because of inbreeeding depression. But this was balanced by a higher survival rates at the seedling stage. A more efficient genetic purge could explain this. However, in our populations, a lower density also induced a lower effective seed production, through an increased rate of empty seeds. This can result from pollen limi tation. Indeed, genetic analyses revealed a rather high spatial genetic structure of pollen pool, indicating a limited dispersal with a mean dispersal distance between 20 and 50m. This limited dispersal also induced a high inter-individual variability of the mating system mainly due to variations of local density and individual pollen production. Finally, we found strong inter-annual variations of the pollen pools : giving an inter-mothers differentiation of 8%, we obtained an inter-annual differenciation of 13% within mothers. The year with the higher pollen productions also presented the lower overall genetic diversity. Thus this study confirms the necessity to consider multiple years in studies on the reproduction of a perennial tree such as fir, either for theoretical concerns of for practical questions focused on the management of genetic diversity

Full textThe ecological functioning of coastal ecosystems is subjected to the synergistic action of climate change and anthropogenic pressures. In Arcachon Bay, the reproductive cycle of the oyster Crassostrea gigas has changed in recent years (e.g. weak gametogenesis, spawning delay). This pattern seems to be associated with global changes in thermal and trophic conditions. The aim of this work was to characterize the spatio-temporal variability in the reproductive investment of oysters in Arcachon Bay. This variability has been investigated in relation to the origin, quantity and quality of the trophic resources. The results revealed important spatial gradients of variability in gonadal development and trophic signal in C. gigas, between inner parts of the bay influenced by river inputs (south-east and north-east) and the external part of the bay, which is influenced by oceanic inputs. Two hydrodynamic factors explained most of the observed variability: immersion time and oceanic water renewal. A comparison of C. gigas gametogenesis and the nutritional value of available food sources between the south-eastern and north-eastern parts of the bay revealed temporal variability in the composition of phytoplankton. This variability was associated with variability in the amounts of essential fatty acids, necessary for gametogenesis. Changes in energy reserves and gamete release cycle were synchronized with the seasonal nutrient variability. These results constitute a first approach in the development of a model predicting the evolution of the energetic needs of C. gigas under the global change in environmental conditions

Full textPrecision livestock farming consists of recording parameters on the animals or their environment using various sensors. In this thesis, the aim is to monitor the behaviour of dairy cows via a real-time localisation system. The data are collected in a sequence of values at regular intervals, a so-called time series. The problems associated with the use of sensors are the large amount of data generated and the quality of this data. The Machine Learning (ML) helps to alleviate this problem. The aim of this thesis is to detect abnormal cow behaviour. The working hypothesis, supported by the biological literature, is that the circadian rhythm of a cow's activity changes if it goes from a normal state to a state of disease, stress or a specific physiological stage (oestrus, farrowing) at a very early stage. The detection of a behavioural anomaly would allow decisions to be taken more quickly in breeding. To do this, there are Time Series Classification (TSC) tools. The problem with behavioural data is that the so-called normal behavioural pattern of the cow varies from cow to cow, day to day, farm to farm, season to season, and so on. Finding a common normal pattern to all cows is therefore impossible. However, most TSC tools rely on learning a global model to define whether a given behaviour is close to this model or not. This thesis is structured around two major contributions. The first one is the development of a new TSC method: FBAT. It is based on Fourier transforms to identify a pattern of activity over 24 hours and compare it to another consecutive 24-hour period, in order to overcome the problem of the lack of a common pattern in a normal cow. The second contribution is the use of fuzzy labels. Indeed, around the days considered abnormal, it is possible to define an uncertain area where the cow would be in an intermediate state. We show that fuzzy logic improves results when labels are uncertain and we introduce a fuzzy variant of FBAT: F-FBAT
