The sudy of the physical ability of sickle cell trait carriers(SCTc) during different kind of exercise (more or less important duration and intensity) reports controversial results. In a first study, we have identified the presence of STCc in a sprint elite population (national French team). The percentages of titles and etablished records of male SCTc are able to performon as well as non-STCc, and eve to have best performances in explosive and brief exercises at the highest level in relation with HbS. The asset of a heightened anaerobic ability in SCTc could be the consequence of a reduced aerobic ability, related to an impaiment of oxygen tranport system consecutive to the decrease of HbS affinity to oxyge. The study of ventilatory and lactic responses during an incremental exercise test did not show any significant difference between groups and did not allow confirming this hypothesis (study n°2). Similary, during three repeated incremental exercise tests, the ventilatory and lactic responses were not significantly different between groups and witnessed to a similar aerobic ability between SCTc and control subjects (study n°3). Regarding the controversy, the data of our studies inclined towards "at least" a similar physical ability between SCTc and non-STCc whatever the contribution of the aerobic metabolism

The tomato spider mites pests Tetranychus evansi and T. Urticae are difficult to control in tomato greenhouses. Their abilities to quickly develop resistances to acaricides, along with the exudation of toxic compounds from hairy solanaceous plants such as tomato and the drought occurring in tomato greenhouses, are important factors that hinder the control of tetranychids in tomato. A predaceous mite of the family Phytoseiidae, Phytoseiulus longipes, is a potential candidate for controlling spider mites outbreaks in these crops. Among the four known populations of this predator, two (from Argentina and Brazil) are able to develop and reproduce well fed on T. Evansi on tomato, while the two others (from Chile and Sout Africa) cannot. After having shown that all those populations actually belong to the same species, studies about the life history and attractiveness of several of those populations depending on prey species/ plant supports allowed to characterize the relationships in the tritrophic system tomato – spider mites – P. Longipes and to confirm that there are two distincts feeding behaviours in this predatory mite species. This phenomena is probably due to a host-plant mediated specialisation for the prey, itself coming from a coevolution between the predator and the complex tomato - T. Urticae and/ or tomato - T. Evansi. Study about the egg hatching response to humidity of P. Longipes showed that this predator is among the four most drought tolerant species studied to date. Furthermore, an analysis of the indirect ecological effects of a possible introduction of P. Longipes, along with the confirmation from semi-field trials that this predator is able to control spider mite pests in tomato greenhouses, lead to the conclusion that P. Longipes is an excellent candidate for the biological control of T. Evansi and T. Urticae in tomato protected crops in Europe

The human remains and excavation archives from 5 cemeteries from the Kadruka concession represented a unique opportunity for the study of the evolution of Neolithic populations and funerary practices in Neolithic Upper Nubia. The aim of this doctoral thesis was to reconstruct the biology of these populations (their health and lifeways) as well as to examine the specific practices at work in the different sequences of the funerary cycle within a chronological framework. Through the study of the 643 individuals (for the biological analysis) and 734 structures (for the archaeological analysis) from KDK 1, KDK 2, KDK 18, KDK 21 and KDK 23 and their comparison, it was possible to discuss the homogeneity of these populations from a biological and cultural standpoint. While the analysis of non-metric anatomical variation (specifically the discrete dental traits) points toward an overall continuity and uniformity throughout the Neolithic, though arguments may also be advanced based on this data for thinking flexibly about population admixture and processes of acculturation following migration patterns that may be multiple and discontinuous. Mortality profiles, non-specific stress markers, and other palaeopathological and occupational indicators, provide evidence of significant variability with biological, as well as cultural implications. Elements related to the processes of change at work within these societies, at a critical chronological and cultural juncture in the Prehistory of Upper Nubia, are perceptible through the study of these funerary groups. For example the exclusion of younger infants within burial areas otherwise including the remains of older individuals, the percentage of carious teeth incidence within populations and the use of teeth as tools, all speak to shifts in economy, subsistence and the structuring of society. While our analysis of funerary practice appears globally homogenous, our data also points to significant variability within an otherwise established and stable funerary sequence (important shifts in grave goods, variable occupation and structuring of the cemetery space, etc.). Finally, this work takes a critical look at the place the Kadruka concession now occupies within the greater understanding of the funerary experience in Prehistoric Sudan, as well as along the Nile river valley and across the Sahara. In examining data from a synchronic and diachronic perspective, across a wide variety of regions and contexts, we achieved our goal of identifying cultural undercurrents, evolutions and particularities for the Kadruka ensemble, as well as for the Sudanese Neolithic more broadly

Fournier, Alice. "Modéliser et prédire les invasions biologiques." Thesis, Université Paris-Saclay (ComUE), 2018. http://www.theses.fr/2018SACLS144/document.
Biologicals invasions, the second cause of biodiversity loss worldwide, represent a major threat that our societies have to face. Invasive species correspond to species that, due to human activities, cross geographic and reproduction barriers and expand into new areas in large numbers. This spread into new ecosystems may have severe socio-economic or ecological impacts. The most efficient way to limit these impacts is to predict and avoid biological invasions before they occur by setting up appropriate management plans.The aim of this PhD thesis is to demonstrate that existing predictive models can be further developed and combined together to improve biological invasion predictions. All of the methods developed in this thesis have been applied to social Hymenoptera: ant species (Formicidae) and the Asian hornet (Vespa velutina nigrithorax), but they are generalizable to any other taxa. The questions asked are: can we predict future invader species? Can we improve the spatial predictions of their distribution? Can we predict invasive species impact?First, I show in this thesis that it is possible to develop a model that detects future invasive species, even before they have had the chance to be moved outside their native range. I apply this screening tool to more than 2000 ant species, provide a list of the 15 ant species that are highly likely to become invasive and map their global suitability to highlights the area the most at risk from these invasions. All continents are threatened by at least one of these potential invasions. Second, I set up a methodological framework to improve species distribution predictions by combining multi-scale drivers. I apply this method to the invasive Asian hornet, identify its high affinity habitats, and use this information to refine suitability maps. I show that integrating multiple drivers, while still respecting their scale of effect, produced a potential range 55.9% smaller than that predicted using a climatic model alone. Finally, I propose a method to predict invasive species impacts in a spatially explicit way and I apply it to the estimate the Asian hornet’s impact on honeybee colonies in France. To do so, I estimate the Asian hornet nest density across France and combine it with an agent-based hive model to estimate honeybee mortality risk. I show that up to 41% of the honeybee colonies are likely to collapse due to the Asian hornet.Overall, these studies demonstrate how modelling techniques can provide valuable inputs to improve invasive species management decision by offering tools to optimize prevention strategies and target areas, species or habitats where action is needed in priority. Biological invasions involve our scientific, political and cultural perceptions in an intricate way; this PhD thesis highlights the usefulness of bringing together modelling techniques and the rest of biological invasion knowledge to better grasp invasion science complexity

Genetic resistances provide an efficient control of crop diseases but are limited by pathogen adaptation.In pepper, the durability of the pvr23 allele, conferring resistance to Potato virus Y (PVY), was demonstrated todepend on the plant genetic background. The aim of my PhD thesis was to characterize the host genetic factorsaffecting the durability of the major resistance gene pvr23 and to answer to the following question s: (i) What istheir action on the evolution of the viral population? (ii) Is there identity between the QTLs (quantitative traitloci) controlling the partial resistance and the QTLs affecting the durability of pvr23? (iii) Are these genetic factorswidespread among the genetic resources of pepper? Various experiments including resistance testing,experimental evolution and competition between various PVY variants, enabled to show that the genetic factorsaffecting the durability of pvr23 acted in: (i) decreasing the viral accumulation, (ii) decreasing the probability ofacquisition of resistance breaking (RB) mutations by PVY and (iii) slowing down the selection of RB variants. QTLdetection and mapping of genetic factors affecting the frequency of pvr23 RB showed that four loci actingadditively and in epistatic interactions explained together 70% of the variance of pvr23 breakdown frequency.Comparative mapping between these QTLs and QTLs affecting partial resistance showed that three of the fourQTLs controlling the frequency of pvr23 RB are also involved in quantitative resistance, suggesting that QTLs forquantitative resistance have a pleiotropic effect on the durability of the major resistance gene. Analysis of acollection of 20 pepper accessions, carrying pvr23 or pvr24 (allele closely related to pvr23) in various geneticbackgrounds, showed that genetic backgrounds favorable to the durability of the pvr2-mediated resistance arewidespread in the genetic resources of pepper. These results highlight that the durability of a major resistancegene can be strongly increased when associated with genetic factors decreasing the pathogen multiplication.Moreover, the frequency of a major gene RB is a highly heritable trait and QTLs detection for this trait isachievable. The direct selection for such QTLs opens new prospects to preserve the durability of major resistancegenes used by breeders

This thesis provides some evolutionary insights on biological invasions, which represent a growing threat on ecology, economy and public health.Biological invasions are a place of rapid and important evolutionary changes that can be the cause or the consequence of invasion success.These changes can be caused by differences in selective pressures between the native and the invaded area.They can also be due to demo-genetic events such as demographic bottlenecks and admixture (emph{i.e.} intra-specific hybridisation) between genetically distinct populations.Evolutionary changes affect life-history traits (including reproductive traits) as well as the genetic load and inbreeding depression.Genetic drift can be strong during a bottleneck and can induce the rapid purging or fixation of deleterious alleles responsible for the genetic load.Reproductive traits can also influence the fate of an invasion by changing the demographic growth rate.Moreover, they can have an indirect impact on the success of introduction by altering the intensity of demo-genetic events.Throughout this thesis, I studied the evolution of the genetic load and of reproductive traits by the mean of (i) laboratory experiments using the invasive Harlequin ladybird Harmonia axyridis as a model species and (ii) through the study of a theoretical model of the dynamics of allele frequencies during a bottleneck.My results show that invasive populations have better reproductive traits than those from the native area.Particularily, invasive females display an increased fecundity and fertilize their eggs with the sperm of a higher number of males.In this species, there is no obvious mechanism of inbreeding avoidance, even though native populations suffer to inbreeding depression contrarily to invasive ones.Inbreeding depression can evolve quickly in this species if the population goes through a severe bottleneck.In my experiments, deleterious alleles were often fixed in the population during the bottleneck, but were sometimes purged.Finally, the theoretical model studied described show that the probability of complete loss or fixation of a deleterious recessive allele can both increase by drift during a bottleneck.These results highlight the importance of chance on the success of a biological invasion.Because the probability of emergence of genomic combinations that can favour an invasion increases with the number of introduction events, limiting the number of introduction events might be an efficient way to prevent or minimise upcoming biological invasions
