• Sommario/riassunto: S'appuyant sur une importante base de donnees anonymisees livree par le ministere de l'Éducation et de l'Enseignement superieur du Quebec concernant plus de 86 000 etudiants et sur pres de deux millions de resultats scolaires au secondaire et au collegial, cette recherche jette un regard critique sur la reussite scolaire dans l'enseignement collegial quebecois. Elle englobe 20 programmes d'etudes de la formation preuniversitaire et 84 programmes de la formation technique ainsi que tous les etablissements publics et prives. Elle decrypte les facteurs cles menant à l'obtention d'un diplôme d'etudes collegiales (DEC) et propose une avenue à emprunter pour augmenter la reussite scolaire dans les cegeps et les colleges par la mise en place de tests de depistage des etudiants à risque de ne pas obtenir le DEC selon la duree prevue ou deux ans apres la fin de la duree prevue. La recherche remet egalement en question plusieurs idees reçues quant à la place du collegial dans la reussite scolaire, à la presence d'effets de composition et au caractere inegalitaire du systeme d'education quebecois. Elle montre aussi que les etablissements collegiaux exercent un effet non negligeable sur la reussite scolaire, independamment des ; caracteristiques des etudiants à leur arrivee au collegial.

• Sommario/riassunto: Endophytes are commonly known as microorganisms, mainly bacteria and fungi, which live inside plant tissues without inducing symptoms. Since the first volume, endophytes have increasingly been shown crucial in the life-style of their hosts. Considering the long-lived trees, endophytes have an even more emphasized role in preparing their hosts to face extreme weather conditions, drought, heat, cold, and pathogen and herbivore attacks. In our changing world, forests are especially important in buffering Earth’s climate, acting as carbon sinks and producing oxygen. The tiny but extremely diverse companions of trees, endophytes, play an essential part in their health. The current knowledge clearly demonstrates the importance of endophytes in shaping the plant diversity in a forest, and endophytes have an important and, still underutilized capacity for biocontrol of forest diseases. In this second volume of ‘Forest Tree Endophytes’, besides interesting updates on the diversity, host specificity, and mechanisms by which endophytes induce growth and health of their hosts, we have collected chapters focusing on the role of endophytes in forest health, diseases and their biocontrol. Considering endophyte diversity and the range of various compounds and enzymes they can produce, endophytes can be used for various biotechnological applications. The widely understudied and underutilized diversity of bioactive compounds of forest endophytes is discussed in updated chapters. .
