La conservation de la biodiversité et l’impact de l’être humain sur celle-ci est au centre de nos préoccupations depuis quelques années. La génomique est une arme puissante qui, associée à de nombreux domaines, permet des avancées considérables. La compréhension du déclin de certaines espèces sauvages et ses répercussions sur le génome et la reproduction, font l’objet de recherches. Dans ce travail, les principes de l’analyse de la qualité de la semence et les principes de la génomique seront abordés. Par la suite, un lien entre ces deux grands domaines sera établi afin de l’appliquer à la problématique de la conservation animale. En effet, si la consanguinité est bien négativement corrélée avec le succès de la reproduction, les causes et les conséquences exactes régissant ce lien ne sont pas claires. C’est pourquoi, à travers l’hypothèse que le degré d’hétérozygotie influence certains paramètres de qualité du sperme, le lien établi entre consanguinité et reproduction peut potentiellement être décodé. Cette hypothèse sera testée sur quarante-six espèces menacées et cinq espèces de références. Enfin, quatre espèces de canidés seront ensuite prises pour exemple. Les résultats obtenus permettent de confirmer statistiquement le lien entre l’hétérozygotie et le pourcentage de spermatozoïdes normaux mais réfutent le lien entre hétérozygotie et motilité. Dans cette étude, un lien est également établi entre l’hétérozygotie et la concentration en spermatozoïdes de l’éjaculat. Il serait donc nécessaire de poursuivre et approfondir les études avant de pouvoir tirer certaines conclusions. The conservation of biodiversity and the impact of the human being on it has been at the center of our concerns for a few years now. Genomics is a powerful weapon that, combined with many disciplinary fields, allows for significant advances. Understanding the decline of some wildlife species and its implications on the genome and reproduction are being studied. In this work, the principles of semen quality analysis and the principles of genomics will be discussed. Subsequently, a link between these two main areas will be established in order to apply it to the issue of animal conservation. Indeed, if consanguinity is correlated with the success of reproduction, the exact causes and consequences governing this link are unclear. Therefore, assuming that the degree of heterozygosity influences certain sperm quality parameters, the link established between consanguinity and reproduction can potentially be decoded. This hypothesis will be tested on forty-six threatened species and five reference species. Finally, four species of canids will then be taken as an example. The results obtained statistically confirm the link between heterozygosity and the percentage of normal spermatozoa but refute the link between heterozygosity and motility. In this study, a link is also established between heterozygosity and the concentration of spermatozoa in the ejaculate. It would therefore be necessary to continue and deepen the studies before drawing certain conclusions.

This book will provide the most recent knowledge and advances in Sample Preparation Techniques for Separation Science. Everyone working in a laboratory must be familiar with the basis of these technologies, and they often involve elaborate and time-consuming procedures that can take up to 80% of the total analysis time. Sample preparation is an essential step in most of the analytical methods for environmental and biomedical analysis, since the target analytes are often not detected in their in-situ forms, or the results are distorted by interfering species. In the past decade, modern sample preparation techniques have aimed to comply with green analytical chemistry principles, leading to simplification, miniaturization, easy manipulation of the analytical devices, low costs, strong reduction or absence of toxic organic solvents, as well as low sample volume requirements.Modern Sample Preparation Approaches for Separation Science also provides an invaluable reference tool for analytical chemists in the chemical, biological, pharmaceutical, environmental, and forensic sciences.

This Topical Collection of Molecules provides the most recent advancements and trends within the framework of food analysis, confirming the growing public, academic, and industrial interest in this field. The articles broach topics related to sample preparation, separation science, spectroscopic techniques, sensors and biosensors, as well as investigations dealing with the characterization of macronutrients, micronutrients, and other biomolecules. It offers the latest updates regarding alternative food sources (e.g., algae), functional foods, effects of processing, chiral or achiral bioactive compounds, contaminants, and every topic related to food science that is appealing to readers. Nowadays, the increasing awareness of the close relation among diet, health, and social development is stimulating demands for high levels of quality and safety in agro-food production, as well as new studies to fill gaps in the actual body of knowledge about food composition. For these reasons, modern research in food science and human nutrition is moving from classical methodologies to advanced instrumental platforms for comprehensive characterization. Nondestructive spectroscopic and imaging technologies are also proposed for food process monitoring and quality control in real time.
