Cette branche de la biologie qui s'occupe les animaux est connue sous le nom de biosystématique animale ; ce qui concerne les plantes, comme Botanique. La biosystématique animale peut être définie comme l'ensemble des faits et doctrines dérivées de l'étude scientifique des animaux. Une étude scientifique exige une observation précise et minutieuse avec une fin définie dans la vue, l'étude scientifique de la biosystématique animale tente de comprendre la structure et l’activités des animaux. Il ne s'occupe pas seulement des animaux en soi, mais aussi avec les relations avec les éléments organiques et inorganiques mondes. Ce polycopié vise à observer les animaux dans leur écosystème, analyse leurs relations avec l'environnement, leurs comportements, leur nutrition. Il participe aux projets de protection d'une ou plusieurs espèces, en alertant éventuellement les autorités publiques sur le danger d'une extinction animale. Par conséquent, ce polycopié constitue de donner aux étudiants, qu'ils se destinent à la recherche ou à la gestion de la biodiversité, les bases nécessaires de phylogénie, de biologie et d'identification morphologiques des principaux groupes animaux. 2025-01-01T00:00:00Z http://dspace.univ-setif.dz:8888/jspui/handle/123456789/6671 Titre: Zoology : The Second year Biology License LMD Auteur(s): LAADEL, Noureddine Résumé: Zoology is the science that studies the animal kingdom. It is a science that utilizes the findings of several disciplines: general anatomy, comparative anatomy, histology, physiology, embryology, paleontology, ecology, and genetics. Taxonomy (or taxinomy): Is the science of biological classification and the development of its laws, based on systematic knowledge. It includes the classification, nomenclature, and identification of specimens. Systematics: Is the arrangement of organisms into groups or taxa according to their similarity or evolutionary relationship, in a coherent system. Nomenclature: Is the branch of taxonomy concerned with assigning names to taxonomic units, according to strict rules (International Code). Identification (or determination): Is the practical application of taxonomy to find the identity of a biological sample and recognize its belonging to an already described taxon. 2025-01-01T00:00:00Z http://dspace.univ-setif.dz:8888/jspui/handle/123456789/6664 Titre: Cell biology Course : For student first year bachelor’s degree in agricultural science Auteur(s): MANSOUR, Linda Maya Résumé: Cell biology is a central discipline in the life sciences. It focuses on the study of cells, which are considered to be the basic structural and functional units of all living organisms. Whether bacteria, animals, plants or fungi, all organisms are made up of cells, which perform all the functions necessary for life: nutrition, reproduction, communication, adaptation, etc. The emergence of cell biology dates back several centuries, but it was in the 19th century that cell theory was formulated, stating that all living beings are composed of cells, and that every cell comes from another cell. Since then, technological advances, particularly in microscopy and molecular biology, have led to a better understanding of the structure and functioning of cells, as well as their interactions within organisms. This course aims to provide the essential foundations for understanding how cells are organised, how they function, how they reproduce and how they communicate with each other. This knowledge is fundamental not only to biology, but also to applied fields such as biotechnology and agricultural science research, including plant and animal breeding. 2026-01-01T00:00:00Z http://dspace.univ-setif.dz:8888/jspui/handle/123456789/6580 Titre: Nutrition and Biochemistry : Course for Master II students Auteur(s): MADOUI, Soraya Résumé: Nutrition and biochemistry are two essential and complementary scientific fields that play a central role in understanding how the human body functions and how it interacts with food. Nutrition focuses on the study of food, its components such as carbohydrates, lipids, proteins, vitamins, minerals and how these nutrients influence health, growth, metabolism, and disease prevention. It also encompasses nutritional needs at different stages of life, eating habits, and the interactions between diet, environment, and society. Biochemistry, on the other hand, examines the chemical and molecular processes that occur within living cells. It helps us understand how nutrients are digested, absorbed, transported, transformed, and utilized at the cellular and tissue levels. Through biochemistry, we can analyze the complex metabolic pathways that convert food into energy, building blocks for cells, and signaling molecules essential for the proper functioning of the body. The connection between nutrition and biochemistry is therefore crucial. Together, they allow us to better understand how our dietary choices directly affect our health at the molecular level. This link is particularly important in today’s context, marked by a rise in chronic diseases related to diet, such as type 2 diabetes, obesity, cardiovascular diseases, and certain cancers. Moreover, recent advances in nutritional biochemistry are paving the way for more personalized approaches to nutrition, taking into account individual metabolism, genetic background, and lifestyle. Studying nutrition through the lens of biochemistry not only deepens our knowledge of the body’s inner workings but also helps develop effective strategies to promote healthy eating, prevent nutritional imbalances, and improve overall quality of life. 2025-01-01T00:00:00Z
