Texte intégralLinear and non-linear models for the analysis of categorical data in animal breeding are reviewed and discussed on account of recent research made in that area. Only non-linear methods based on the threshold liability concept introduced by Wright are described. Emphasis is on describing statistical techniques for estimating genetic merit and parameters of genetic and phenotypic variation. For the non-linear threshold model, it is shown how Bayesian methodology is particularly well suited for estimating location and dispersion parameters in the underlying scale under mixed sources of variation. The generality of this approach is illustrated through a discussion of several situations in which this procedure can be applied (ordered polychotomies, multiple binary responses, mixture of binary and normal traits)

Texte intégralRecent advances in biotechnology allow the monitoring of large quantities of biological data of various types, such as genomics, proteomics, metabolomics, phenotypes. . . , that are often characterized by a small number of samples or observations. The aim of this thesis was to develop, or adapt, appropriate statistical methodologies to analyse highly dimensional data, and to present efficient tools to biologists for selecting the most biologically relevant variables. In the first part, we focus on microarray data in a classification framework, and on the selection of discriminative genes. In the second part, in the context of data integration, we focus on the selection of different types of variables with two-block omics data. Firstly, we propose a wrapper method, which agregates two classifiers (CART or SVM) to select discriminative genes for binary or multiclass biological conditions. Secondly, we develop a PLS variant called sparse PLS that adapts l1 penalization and allows for the selection of a subset of variables, which are measured from the same biological samples. Either a regression or canonical analysis frameworks are proposed to answer biological questions correctly. We assess each of the proposed approaches by comparing them to similar methods known in the literature on numerous real data sets. The statistical criteria that we use are often limited by the small number of samples. We always try, therefore, to combine statistical assessments with a thorough biological interpretation of the results. The approaches that we propose are easy to apply and give relevant results that answer the biologists needs

Texte intégralBreeding plans in honeybees are emerging worldwide, aiming to improve traits such as production and resilience. However, beekeepers lack references and methods to optimize selection. Indeed, three bee specificities complicate the application of general breeding theory: haplo-diploidy, early and polyandrous queen mating, and colony-level trait expression. Considering these specificities, this thesis explores selection strategies, estimation of genetic parameters, and contributes a stochastic simulation tool of bee breeding schemes.Regarding selection strategies, simulations showed that monoandry (queen fertilized by a single male) over 20 years of phenotypic selection favors gain on genetic effects expressed by worker groups over those expressed by queens and leads to similar or lower total genetic gain compared to polyandry, and 25-50% higher inbreeding. Mass selection yields 20% more genetic gain than within-family selection but increases inbreeding by 33%.Early dam selection based on estimated breeding values shortens generation intervals by a third and can increase genetic gain by up to 50%, depending on the breeding goal, despite impeding late-trait phenotyping on dam selection candidates.Regarding the estimation of genetic parameters, the simulations show that when all drones mating a queen originate from a single drone-producing queen (DPQ), standard errors of genetic estimates decrease by 10% compared to when drones originate from three sister-DPQs. However, pedigree uncertainty on which of these two mating strategies is used can severely bias genetic estimates. DPQs are often open-mated because they don't transmit the genetic material obtained from their mates to further generations of the breeding population. It is shown that correction of DPQ-colony phenotypes, by adding a non-genetic effect in the evaluation model for the drone subpopulations mating DPQs, avoids bias in genetic parameter estimates.Using data from a small breeding population in Southern France, genetic parameters for beekeeping traits, fecundity, and resilience traits were estimated. Despite uncertainty due to limited data, most traits, including those related to resilience, indicated potential for selection, while swarming drive and gentleness showed no heritability.This thesis work aims to guide bee breeders in the genetic improvement and inbreeding control of their stock. The simulation tool developed in this thesis is publicly available to explore breeding plans for honeybees further

Texte intégralThe Global Health concept emerged in the early 2000s, on the premise that there is an interrelationship between human actions and the emergence of diseases with pandemic potential. This integrative approach is based on a holistic process linking livestock farming practices, their ecosystems and humans in close or less close contact with these animals.The work presented here relies on the mobilization and development of molecular and analytical tools aimed at securing and optimizing an early phase of our food system: animal selection and reproduction. The production of animal semen, particularly boar semen, is characterized by its widespread fresh production and distribution. As a result, it is usually conditioned, upon dilution, through the use of antibiotics. Antibiotic formulations used in this context are developed empirically. As a result, it provides an original model for studying the emergence of antibiotic-resistant bacteria.Based on this production, which underpins the agri-food industry, the work presented will aim to demonstrate how genomic tools can contribute to a better understanding of the emergence of resistant bacteria, and how they can be applied to provide solutions to reduce the risk of such an emergence. An extension to other contexts will reveal the potential of these approaches to improve the effectiveness of human and animal infection management. The proposed work and itinerary relate, on the one hand, innovative applications built on genomic technologies and, on the other hand, attempt to establish bridges and opportunities for transferring methodologies between livestock and human health applications

Texte intégralFish swim to accomplish such essential activities as prey capture, avoiding predation, migrating, mating. Despite the vital nature of swimming, there is evidence that individuals of a fish species show wide variation in their ability to swim. This thesis investigated individual variation in major traits of aerobic and anaerobic swimming performance in the European sea bass (Dicentrarchus labrax); the extent to which trait variation was stable and repeatable over time, and whether the variation reflected trade-offs between different types of performance. Maximum aerobic swimming speed was remarkably uniform in the sea bass, and highly repeatable, indicating selection for individuals which can preserve maximal aerobic function at all times. By contrast, traits of anaerobic performance, such as maximum anaerobic bursting speed, maximum sprinting speed, and the fast-start escape response, all show a high degree of individual variation. Variation in maximum anaerobic bursting speed may reflect a trade-off whereby high performance requires a significantly longer recovery period. The basis for the variation in sprinting speed and escape response is unknown, although the variation was relatively stable and repeatable over time. There were no clear relationships between the different independent performance traits in the sea bass, despite the fact that a negative relationship (trade-off) between aerobic and anaerobic performance had been predicted on theoretical grounds, as had positive relationships between different types of anaerobic performance. Thus, the large degree of variation in anaerobic performance cannot be explained at present, but may reflect a life cycle of seasonal colonization of diverse habitats, where no single performance phenotype has an adaptive advantage

Texte intégralSince the early 2000s, the development of genomics, which enables extensive knowledge of the DNA of living entities, has transformed the way in which living entities are evaluated, selected (genomic selection of plants and animals) and marketed. Coupled with political and regulatory changes, this technology contributes to modify the national institutional arrangements in the targeted field of animal genetic improvement, practices of actors. The current liberalization process questions both the collective dimension of genetic progress and the property rights of the genetic resources. In a comparative perspective between France, Ireland and The Netherlands, the objective of this thesis is to analyze the plurality of institutional arrangements pertaining to the Holstein cattle breed’s genomic selection. This thesis is situated within the recent evolutions of the neo-institutional theory focused on organizational heterogeneity and materiality of institutions. Firstly, it highlights three institutional regimes that reveal different arrangements particularly between public and private organizations. Secondly, this diversity of arrangements is completed by an analysis of contractual tools between breeding companies and animal breeders through models of production strategies and exchanges related to genetic resources (both biological and informational forms). These models emphasize a variety of property forms of genetic resources between companies and breeders and also show that actors’ roles in genetic selection activities are redefined. These results provide a better understanding of the development of a liberal logic (The Netherlands) in duality with the reinforcement (Ireland) or weakening (France) of a cooperative logic for the production of improved animal genetics
Estivals, Guillain. « Spéciation sympatrique chez les cichlidés en Amazonie ? : spéciation et sélection sexuelle dans le modèle Apistogramma agassizii (Steindachner, 1875) ». Thesis, Paris, Muséum national d'histoire naturelle, 2020. http://www.theses.fr/2020MNHN0002.
Texte intégralWe chose the Apistogramma agassizii model to test for rapid, potentially sympatric, speciation in Amazonian cichlids. A. agassizii shares many similarities with Haplochromines cichlids which are remarkable examples of adaptive radiations in vertebrates. Like the Haplochromines, A. agassizii is philopatric, and show: an important colour polymorphism with marked sexual dimorphism, a differential partner selection, and parental care. We sampled 1170 individuals of A. agassizii from 36 popsites (smallest collection unit) located in the Loreto region of the Peruvian Amazon. The genetic variability of A. agassizii throughout the study area was studied using 2 mitochondrial markers (COI and Cyt b) and 10 microsatellite loci.The 1170 individuals was genotyped, of which 104 were sequenced for both mitochondrial markers. A total of 44 haplotypes were obtained from the concatenated sequences. The results revealed 3 vicarious "species flocks" (named, Sp1, Sp2 and Sp3) that would have started to diverge from their most recent common ancestor (MRCA) 1.83 Ma ago (calibration from fossils).The degrees of genetic differentiation of the 3 "species flocks" would be fractally organised according to the hierarchy of the hydrographic network. The values of genetic differentiation (FST estimator θ) that we observed within the "species flocks" had never before been observed on such small geographical scales for a fish in the Amazon (Sp1: 0.04 - 0.37, avg. = 0.16 ± 0.06 (σ); Sp2: 0.08 - 0.40, avg. = 0.17 ± 0.09 (σ)). Thus, large rivers within sub-watersheds, such as the Marañon, Ucayali and Amazon, would constitute the hierarchical level of rank 1. They would limit the dispersion of the 3 evidenced "species flocks" Sp1, Sp2, Sp3, by constituting barriers to genes flow and possible allopatric speciation. The micro-watersheds would constitute the lower hierarchical level of rank 2, with genetic differentiations of variable amplitude structuring the species flocks in sympatry. The term "sympatry" being used here in the broad sense, considering that these micro-watersheds are very close to each other and are connected by a main river on the same bank. Finally, within the micro-watersheds, the streams would constitute the hierarchical level of rank 3 in which proto-species (genetic unit whose speciation process may be reversible) would diverge in strict sympatry, between connected streams, or even within the same stream (within the same popsite or collecting site). We have shown that the evolutionary history of the "species flock" Sp1 had been conditioned by multiple hydro-geomorphological events which would have alternately favoured fragmentation or dispersion events inducing mixtures of populations in secondary contact. Mate choice experiments were carried out taking into account the 3 identified hierarchical levels. At hierarchy level 1 (sub-watersheds), females Sp1 and Sp2 preferentially chose males of their own "species flock" (Sp1: p-value = 0.0005; Sp2: p-value = 0.0029). Mate choice experiment for level 2 (micro-watersheds) and 3 (stream) were carried out within the species flock Sp1. We tested the choice of females by offering them a male from their stream (same micro-watersheds) and a male from a stream in another micro-watersheds. For level 3 we tested the choice of females by offering them a male from their stream and a male from another stream belonging to the same micro-watersheds. In both configurations, females generally showed sexual preference according to male origin, but this could not be tested in sufficient depth to corroborate that sexual selection would play a driving role in the process of sympatric speciation.The evolutionary mechanisms highlighted in the Apistogramma agassizii model could also be involved in the diversification of other Cichlid species, or even other groups of organisms in the Amazon, and partly explain the exceptional species diversity in the world's largest watershed
