Full textThe hypothesis of ecological speciation states that the selection of adaptive traits in different ecological niches can causes reproductive isolation, even if populations under divergent selection are not geographically isolated. Documented examples of ecological speciation are scarce, but specialized phytophagous insects feedingon restricted host ranges are good candidates. Indeed, specialization of insect populations of different host plants can cause various forms of reproductive isolation, such as habitat isolation or temporal isolation. The pea aphid, Acyrthosiphon pisum, thus presents genetically differentiated and highly specialized sympatric biotypes feeding on restricted host ranges are good candidates.

Full textSoon after its appearance at the beginning of the Tertiary, the Primate order underwent several successive episodes of diversification which were the basis for the emergence of the higher taxonomic groups that can be observed in nature today. Despite the importance of these events, little is known regarding the factors that governed them, in particular the importance of the ecological factors involved. The Paleocene-Eocene transition in North America and Europe was marked by a period of major global warming. It was during this time that modern primates (Euprimates) appeared and dispersed before experiencing an explosive diversification throughout the Eocene. This study aims to characterize the emergence of this diversity through the identification of ecological factors, such as environment, resource partitioning and competition. In this framework, the study of dental structure and of dental microwear is used to reconstruct the diet of Paleogene primates (Adapiformes, Omomyiformes, Anthropoidea and Plesiadapiformes), one of the best indicators of the ecology of a given animal. In Europe, although exhibiting a dental morphology better suited to insect-eating, the first euprimates (e.g., Donrussellia [adapiformes]) were fruit-eaters, only supplementing their diet with insects. They mostly occupied different niches to co-occurring plesiadapiforms (leaf-, fruit- and gum-eaters). The diversification of euprimates led to the increasing competition among primate communities and to the apparition of different dietary specializations. For example, Adapines, initially having a diet based on fruit, show a dietary shift by incorporating leaves and harder objects in their diet.In Asia, the study of fossil primate communities has highlighted resource partitioning and competition among small-bodied primates (eosimiids, tarsiids, and adapids), which all had a diet based on fruit and insects. Asian anthropoids (amphipithecids) show some singular ecological specialization towards sclerocarpic foraging.In Africa, Eocene primates show a high diversity, with the colonisation of numerous ecological niches such as insect-eating (adapiformes), fruit-eating (adapiformes, strepsirhines and anthropoids) et leaf-eating (adapiformes, anthropoides).This study highlights dietary diversity and variability which can exist for a given primate (extant or fossil) according to factors which can be biological in nature (i.e., competition) or not (i.e., environment, geography). The comparison between the different continents demonstrates that primates (Adapiformes, Omomyiformes, and Anthropoidea) occupied different niches in different primate communities. These differences in resource partitioning and competition are most probably reflected in the different paths these adaptive radiations took

"Histoire évolutive des remaniements chromosomiques en liaison avec la mobilisation d'éléments transposables chez les téléostéens antarctiques Nototheniidae : la radiation adaptative du groupe " Trematomus "." Thesis, Sorbonne université, 2018. http://www.theses.fr/2018SORUS371/document.
Full textIn the last 20 My, multiple glacial-interglacial cycles led to strong and repeated environmental changes on the Antarctic continental shelf. In this changing environment, nototheniid fishes diversified through several rounds of species radiation (one of which within Trematominae), and now constitute the dominant group in Antarctic teleosts. Among Nototheniidae, the group « Trematomus » (genera Cryothenia, Pagothenia, Trematomus and Indonotothenia) exhibits the highest chromosomal diversity, with diploid chromosome numbers ranging between 24 and 58, involving many rearrangements probably linked to speciation. We characterized the nature of these chromosomal repatternings. With an inferred ancestral state of 2n = 48 acrocentric chromosomes, a conserved number of chromosomal structural units, and a constancy of the genomes sizes we measured; the hypothesis of structural modifications is favored rather than a whole genome duplication associated to drastic reductions. In order to reconstruct an evolutionary scenario of such chromosomal rearrangements accompanying the trematomine diversification, we identified interspecific chromosomal homologies. This allowed us to reconstruct the rearrangements events (mostly centric and tandem fusions). We plotted them on a phylogeny we reconstructed based on our own ddRAD-seq data. Contrary to what was reported for the Notothenia, our results are in favor of independent acquisitions. Transposable elements (TEs) can lead to chromosomal rearrangements through ectopic recombination events, hinting at a role as drivers of specific-lineage diversification. Moreover, due to their epigenetic regulation, TEs can be mobilized when thermic changes occur. We focused on three retrotransposon superfamilies (DIRS, Gypsy and Copia) in nototheniid genomes. The DIRS1 showed unexpected accumulation patterns of insertion in the centromeric and pericentromeric regions. Given the mechanism of DIRS1 transposition and their tendency to sometimes insert on pre-existing copies (homing), we suggest a role of DIRS1 elements as facilitators of the fusions that occurred during the trematomine radiation

Full textThe evolution of mammalian dentition is defined by profound morphological modifications as occlusion and heterodonty. Among rodents, characterized by a reduced dental formula, arvicolines have a highly derived dentition, with prismatic and hypsodont molars. The aim of this Ph.D thesis is to explore various morphological innovations through developmental and adaptive aspects. Geometric morphometric methods were used on molars, incisors and mandibles to investigate the dynamics of development and evolution of dentition. A developmental model predicting molar proportions is tested and confirmed for the rodent order; it could be also extended to the premolar. The relationship between dental morphology, in particular molar proportions, and diet is complex, diet being not directly inferred from one morphological trait. Yet, covariations between molars inform on masticatory movement and thus on function. Our results confirmed that morphologies could be understood from a complex combination of historical, functional and developmental constraints. The various structures of the mandible have a complex hierarchical organization. The development of mammalian dentition is controlled by similar processes but through times, mechanisms as heterochrony may lead to a diversification of phenotypes

Full textImaging is now fully integrated in the radiation therapy process. With on-board CBCT systems, tomography imaging allows not only patient positioning but also treatment planning adaptation with patient anatomy modifications, throughout the entire treatment. This is called adaptive radiation therapy, and is the main subject of this PhD thesis. During this work, we measured the repositioning accuracy of the system used. We also developed a treatment strategy using daily CBCT images and a personalized plan database to adapt treatment plan to patient anatomy. We found a way to select the daily treatment plan that shows superiority over operator selection. Then we also quantified the additional dose delivered while using this technique and the impact with regards to the risks added to patients. As a conclusion, with CBCT imaging, radiation therapy has entered an era where one can see what need to be treated, can treat what has been seen and can control what has been treated

Thesis, Institut polytechnique de Paris, 2019. http://www.theses.fr/2019IPPAX010.
Full textPrenatal exposure to ionizing radiation has been associated with many neurodevelopmental disorders due to the DNA damage induced in neural stem and progenitors cells (NSPC). Thus, genetic stability of NSPC is crucial for brain development and homeostasis. Nevertheless, genomic alterations occurring during development in NSPC may have a potential impact on the physiological neuronal diversity. XLF is a component of the NHEJ (Non-Homologous End-Joining) repair pathway. Here, we show that NSPC from Xlf-/- embryos exhibit increased chromosome instability, leading to premature neurogenesis and consequently neurobehavioral disorders. Using cytogenetic approaches, we compared the chromosome stability of mouse embryonic NSPC and fibroblasts (MEF) exposed to acute (γ-irradiation) or chronic (incorporation of tritiated thymidine into DNA) genotoxic stress. Our results demonstrate the higher capacity of NSPC as compared to MEF to maintain their genomic integrity. We evidenced that NSPC have more efficient DNA repair activity than MEF, allowing them to develop an adaptive response to chronic genotoxic stress. This adaptive response involves XLF and acts together with apoptosis and cell cycle checkpoints to preserve the stability of the genome and to eliminate damaged cells. Altogether, our results provide new insights into the robust DNA damage response in NSPC and highlight the importance of Xlf during brain development
